UGC NET Paper 2: Economics 2nd Mar 2023 Shift 1 (Previous Year Paper)

Option 4 is the right answer. 

Key Points

• The Producer’s equilibrium is the point where all of the variables used in production are at their respective minimum amounts.
• At this point, all costs would be zero, meaning that there would be no prices involved, and everyone would receive a profit. However, it is not entirely true that the Producer’s equilibrium is reached at this point.
• To achieve his goal of producing maximum output with minimal costs, the Producer must also have cash on hand to pay for such items as raw materials, labour services, and rent on fixed capital equipment.
• 
• Producer's equilibrium occurs at the tangency of isocost and isoquant, where MRTS equals factor price ratios.
• MRTS=w/r.

The correct answer is Indifference curve for two normal goods is a downward sloping straight line.

Key Points

• The Indifference curves are usually convex or bowed inward.
• The reason indifference curves are usually convex, or bowed inward, towards the origin is due to a principle known as diminishing marginal rate of substitution (MRS).
• The marginal rate of substitution is the amount of a good a person is willing to give up to get an additional unit of another good, and still remain equally satisfied (on the same indifference curve). As a person consumes more and more of one good, the willingness to give up units of the second good to get more of the first good declines. This is the idea of diminishing marginal rate of substitution.
• Indifference curve for two goods that are perfect compliments is shaped as right angles.
• An indifference curve is a graph that shows a combination of two goods that a consumer considers equally preferable, meaning they have the same level of satisfaction (or utility) with any of the combinations.
• When the two goods are perfect complements, it means they are used together in a fixed ratio. Think of a car and gasoline, or a pen and ink. You need both together to achieve the desired use. Increasing one without the other doesn't add any value or satisfaction to the consumer.
• Indifference curve for two goods that are perfect substitutes is a downward sloping straight line.
• Two goods are considered perfect substitutes if the consumer is perfectly okay with consuming one good instead of the other. That means the two goods are completely interchangeable from the consumer's viewpoint. For example, imagine if you had two brands of plain bottled water – most people would be indifferent as to which brand of water they drink.

Non-zero sum game. 

Key Points

• A Non-Zero-Sum Game is a situation where one's win does not necessarily mean another's loss, and one's loss does not necessarily mean that the other party wins.
• In a Non-Zero-Sum Game, all parties could gain, or all parties could lose. This is in direct contrast to a Zero-Sum Game where one party's win necessitates another party's loss, such as in competitive games like basketball,  where if one team wins, the other automatically loses.
• A classic example of a Non-Zero-Sum Game situation is called the Prisoner's Dilemma, where two prisoners are interrogated separately, and are offered a bargain where if one confesses, he is set free, while the other prisoner is convicted for 10 years.
• If both confess, they both face 2 years in prison. If both keep their mouth shut, they would both serve 6 months for a minor crime.
• Obviously, the optimal choice for both of them would be to keep silent and serve the 6 months. But since they don't know what the other person intends to do, they will both fear that the other one might confess, leaving them to suffer the 10 years.

The condition of preferring a risky income to a certain income with the same expected value is refered as risk loving. 

Key Points 

• Risk lovers gravitate towards investments with extremely high potential payouts even if the potential for loss is comparatively larger.
• The types of investment a risk lover is willing to consider are the same ones that common valuation methods filter out.
• Risk lovers play an important market function by helping de-risk the market for more conservative investors.

Economies of Scope is the right answer. 

Key Points

• An economy of scope means that the production of one good reduces the cost of producing another related good.
• Economies of scope occur when producing a wider variety of goods or services in tandem is more cost effective for a firm than producing less of a variety, or producing each good independently.

In such a case, the long-run average and marginal cost of a company, organization, or economy decreases due to the production of complementary goods and services.

 Additional Information

• While economies of scope are characterized by efficiencies formed by variety, economies of scale are instead characterized by volume. The latter refers to a reduction in marginal cost by producing additional units.
• Economies of scale, for instance, helped drive corporate growth in the 20^th century through assembly line production.

Bertrand model is the correct answer. 

Key Points

• Bertrand competition is a model of competition used in economics, named after Joseph Louis François Bertrand (1822–1900).
• It describes interactions among firms (sellers) that set prices and their customers (buyers) that choose quantities at the prices set. The model was formulated in 1883 by Bertrand in a review of Antoine Augustin Cournot's book Recherches sur les Principes Mathématiques de la Théorie des Richesses (1838) in which Cournot had put forward the Cournot model.
• Cournot's model argued that each firm should maximise its profit by selecting a quantity level and then adjusting price level to sell that quantity.
• The outcome of the model equilibrium involved firms pricing above marginal cost; hence, the competitive price.
• In his review, Bertrand argued that each firm should instead maximise its profits by selecting a price level that undercuts its competitors' prices, when their prices exceed marginal cost.
• The model was not formalized by Bertrand; however, the idea was developed into a mathematical model by Francis Ysidro Edgeworth in 1889.

The correct answer is Adam Smith.

Key Points

• When the division of labour has been thoroughly established, it is but a very small part of a man’s wants that the produce of his labour can supply. He supplies the far greater part of them by exchanging that surplus part of the produce of his labour, which is over and above his consumption, for such parts of the produce of other men’s labour as he has occasion for. Every man thus lives by exchanging or becomes in some measure a merchant, and the society itself grows to be what is properly a commercial society.
• "The Wealth of Nations," written by the influential economist Adam Smith. Published in 1776, the book provides one of the world's best-known rationales for free trade, competition, and the efficiency of market economics.

The correct answer is Real wage rises.

Key Points

• If the demand for labor increases, typically two main outcomes can be expected in the labor market.
• Wage increases: Higher demand for labor generally results in an increase in wages, as firms are willing to pay more to attract the workers they need. This is based on the basic economic principle of supply and demand -- as demand rises while supply remains the same, the price, in this case, wages, should rise.
• Employment increases: If the demand for labor increases, it means more jobs are being created in the economy, which leads to an increase in employment. Companies hiring more workers can lead to a reduction in unemployment rates, assuming there's a sufficient supply of workers.
• These outcomes, however, rely on a number of assumptions, like the flexibility of wage rates, the preparedness and ability of the labor force to fill the new jobs, and how effectively the labor market matches workers to jobs. For example, there could be a situation where the demand for labor increases in a certain high-skill industry, but there may not be a sufficient supply of workers who possess these specific skills. Furthermore, changes might not be immediate as labor market adjustments often take time.

The correct answer is The upward-sloping short-run aggregate supply curve.

Key Points

• The Sticky-Price Model is an economic concept used in macroeconomics to explain how prices of goods and services adjust in the short run. According to this model, prices don't adjust instantly to changes in supply and demand but instead change slowly over time.
• The term "sticky" implies that prices tend to remain fixed or adjust only gradually.

Additional Information

• Price stickiness, or sticky prices, is the failure of market price(s) to change quickly, despite shifts in the broad economy suggesting a different price is optimal.
• When prices cannot adjust immediately to changes in economic conditions or in the aggregate price level, there is an inefficiency or disequilibrium in the market.
• Often the price stickiness operates in just one direction—for instance, prices will rise far more easily than they will fall.
• The concept of price stickiness can also apply to wages. When sales fall, the company doesn’t resort to cutting wages

The correct answer is Monetary economy.

Key Points

• To sum up, macroeconomics distinguishes between the real economy and the monetary economy. The real economy deals with the production and consumption of goods and services, while the monetary economy deals with the creation, distribution, and use of money.
• The monetary economy refers to the part of the economy that deals with the creation, distribution, and use of money. It includes institutions such as banks, central banks, and financial markets. In the monetary economy, money is used as a medium of exchange, a store of value, and a unit of account. The monetary economy is measured by indicators such as money supply, interest rates, and exchange rates.

The correct answer is Constant.

Key Points

• In accelerator theory, the capital-output ratio (also known as the capital coefficient) is typically assumed to be constant. The theory is based on the notion that investment levels are determined by rates of change in income or consumption. It is seen as a response to changes in the rate of economic growth.
• This constant capital-output ratio assumption suggests a fixed relation between the capital stock necessary to produce a given level of output. If the demand for output increases, causing output to rise, firms will correspondingly need to increase their capital stock to meet this new demand level—thus, maintaining the constant capital-output ratio.
• However, one should note that this is an assumption to simplify the model, and in the real world, the capital-output ratio can change due to multiple factors, including advances in technology, changes in labor efficiency, and shifts in production processes

The correct answer is All of the above

Key Points

• Government spending refers to money expended by the public sector, funded by national revenues, to administer and manage the state and its objectives. The sources of such funds can be taxes, government borrowing, or revenue from government-controlled entities.
• Government spending can be categorized into three main types:
• Current Spending (or revenue spending): These are recurring and usually cover wages, rents, and daily expenditures.
• Capital Spending: These are expenditures that result in the acquisition of assets or the enhancement of existing assets. These could include infrastructure projects, such as highways, airports, schools, hospitals, etc.
• Transfer Payments: This is money the government gives without receiving goods or services in return, like social security benefits, unemployment benefits, welfare payments, and pensions.
• The allocation and volume of government spending can have a significant impact on a country's economy, affecting everything from economic stability, and income distribution, to the level of infrastructure development.

Key Points 

• When tossing two coins simultaneously, the possible outcomes for the number of heads are 0, 1, and 2. Let's denote the random variableX as the number of heads. The probability distribution for ���

  X is as follows:

• P(X=0)=1/4

• P(X=1)=1/2

• P(X=2)=1/4

Additional Information

• μ= 0.(1/4)+1(1/2)+2.(1/4)

• μ=1

• let's find the variance (�2�2�2

  σ2) using the formula:

• Variance= (0-1)² . 1/4 +(1-1)² .1/2 + (2-1)². 1/4

• Variance= (1/4)+(1/4)

• Variance=1/2

The correct answer is 32 / 9.

Key Points

• To find the Producer's Surplus, we must first determine the Market Equilibrium by setting the Demand Function equal to the Supply Function. The given functions are Pd = 20 - 5x and Ps = 4x + 8.
• Equating the two: 20 - 5x = 4x + 8. Solving for x (the equilibrium quantity), we get 9x = 12, which simplifies to x = 12 / 9 or x = 4 / 3. This is the equilibrium quantity (x0).
• Next, we find the equilibrium price (P0) by substituting x = 4 / 3 into the supply function: Ps = 4(4 / 3) + 8 = 16 / 3 + 8 = (16 + 24) / 3 = 40 / 3.
• The formula for Producer's Surplus (PS) is: PS = (P0 * x0) - ∫[0 to x0] S(x) dx.
• Calculation of P0 * x0: (40 / 3) * (4 / 3) = 160 / 9.
• Integration of the supply function: ∫ (4x + 8) dx from 0 to 4 / 3 = [2x^2 + 8x] evaluated from 0 to 4 / 3.
• Evaluation: 2(4 / 3)^2 + 8(4 / 3) = 2(16 / 9) + 32 / 3 = 32 / 9 + 96 / 9 = 128 / 9.
• Finally, Producer's Surplus = 160 / 9 - 128 / 9 = 32 / 9. Hence, the correct answer is 32 / 9.

Additional Information

• Producer's Surplus: It is an economic measure of the difference between the amount a producer of a good receives and the minimum amount the producer is willing to accept for the good. It is the area above the supply curve and below the equilibrium price.
• Consumer's Surplus: While not asked here, it is the counterpart to producer surplus. It is the difference between the maximum price a consumer is willing to pay and the actual price they do pay. It is the area below the demand curve and above the equilibrium price.
• Supply Function (Ps): The function 4x + 8 represents a linear supply curve with a price intercept of 8. This means producers require at least a price of 8 to start supplying any quantity of the good.
• Demand Function (Pd): The function 20 - 5x represents a downward-sloping demand curve where 20 is the choke price (the price at which demand becomes zero).
• Economic Significance: The sum of Consumer's Surplus and Producer's Surplus is known as Total Social Surplus. In a perfectly competitive market, the equilibrium point maximizes this total surplus, ensuring allocative efficiency.

Important Points

• Calculus in Economics: The use of definite integrals is fundamental in determining welfare measures like surpluses. The integration represents the total variable cost (the area under the supply curve) when calculating producer surplus.
• Numerical Values: Note that the equilibrium price (40/3) is approximately 13.33 and the equilibrium quantity (4/3) is 1.33. The resulting Producer's Surplus (32/9) is approximately 3.55 units of currency.
• Assumptions: These calculations assume that the market is in static equilibrium and that the functions are continuous and integrable over the range from 0 to the equilibrium point.
• Application: Government agencies and economists use these metrics to evaluate the impact of taxes, subsidies, and price ceilings on the welfare of producers and consumers in a country.

the cross - price elasticities of demand at PA = 6, Y = 500, PB = 10 is 0.016 approximately.

Key Points

• Cross-price elasticity measures how sensitive the demand of a product is over a shift of a corresponding product price.
• Often, in the market, some goods can relate to one another. This may mean a product’s price increase or decrease can positively or negatively affect the other product’s demand.
• Cross E of x and y equals % change in Qx with respect to % change in Px Where:

Qx = Average quantity between the previous quantity and the changed quantity, calculated as (new quantityX + previous quantityX) / 2

• Py = Average price between the previous price and changed price, calculated as (new pricey + previous pricey) / 2

Δ = The change of price or quantity of product X or Y

• Substitute PA=6,Y=500,PB=10

into the demand function to calculate QA

: QA=100−2(6)+0.2(500)+0.3(10)=100−12+100+3=191.

• Substitute the values into the elasticity formula:  E_C = 0.3 {10}/{191} = {3}/{191} = 0.016.
• The cross-price elasticity of demand is therefore 0.016

The correct answer for the given question is option 1. The Elasticity of Substitution of Constant elasticity of substitution (CES) Production function is greater than 1 when the substitution parameter lies between 0

The correct answer is '7 / 18.'

Key Points

• Probability Basics:
• Probability is the measure of the likelihood that an event will occur, calculated by dividing the number of favorable outcomes by the total number of possible outcomes.
• When selecting items without replacement, the probability changes as items are removed from the pool.
• Calculating the Desired Probability:
• We need to find the probability that one glove is left-handed and the other is right-handed when two gloves are selected without replacement from a box of nine gloves (2 left-handed and 7 right-handed).
• The total number of ways to choose 2 gloves out of 9 (29​)=2!(9−2)!9!​=36.
• The number of favorable outcomes where one glove is left-handed and the other is right-handed can be calculated by multiplying the number of ways to choose 1 left-handed glove from 2 and 1 right-handed glove from 7 is 14.
• Therefore, the probability of selecting one left-handed glove and one right-handed glove is 14/36 = 7/18
• Therefore, the correct answer is '7 / 18.'

Third Five Year Plan. 

Key Points

• The focus was on agriculture and improvement in the production of wheat.
• States were entrusted with additional development responsibilities. Ex- States were made responsible for secondary and higher education.
• Panchayat elections were introduced to bring democracy to the grassroots level.
• The target growth rate was 5.6% and the actual growth rate only achieved 2.4%
• This indicated a miserable failure of the Third Plan, and the government had to declare "Plan Holidays" (1966-67, 1967-68, and 1968-69). The Sino-Indian War and the Indo-Pak War, which caused the Third Five Year Plan to fail, were the primary causes of the plan holidays.

The correct answer is Real money supply.

Key Points

• The nominal money supply is the total amount of money in circulation in an economy. It includes all the currency and other liquid instruments in a country's economy as of a particular time. The nominal money supply does not adjust for inflation and is not related to the purchasing power of the money. It's simply the face value of the money in circulation.
• Real narrow money refers to the money supply in an economy, adjusted for inflation, and considering only the most liquid forms of money. Narrow money usually refers to the most liquid instruments, such as currency in circulation (coins and banknotes) and other money equivalents that can be quickly converted into physical cash, like checking accounts.
• Nominal broad money is the measure of broad money that has not been adjusted for inflation. The term "nominal" means that the measurement has not factored in inflation, so increases in nominal broad money could be due to real growth (more money being held), inflation (the value of money decreasing), or a combination of both.
• Real money supply' means the total amount of money available in the economy, but with the effect of inflation taken into account. This provides a measure of the purchasing power of the money supply—how much goods and services this money can actually It helps to provide a more accurate sense of the economic reality and the available liquidity in the economy.

The correct answer is 60,000/ - crore.

Key Points

• The "Har Ghar Nal se Jal" scheme or the Jal Jeevan Mission is a program initiated by the Government of India with the aim to provide piped water supply (Har Ghar Nal se Jal) to all rural and urban households by 2024. The program was launched in August 2019 by Prime Minister Narendra Modi.
• An allocation of Rs. 60,000 crore has been made to cover 3.8 crore households in 2022-23 under Har Ghar, Nal Se Jal Scheme.
• Finance Minister said that the currect coverage of Har Ghar, Nal Se Jal is 8.7 corres.
• Outof which 5.5 crore households were provided tap water in the last two years itself.

Additional Information

• Over 8.60 Crore Tap Water Connections provided in last 4 Years Up from 3.23 Crore in 2019 to 11.84 Crore till date One tap connection every second during January – March 2023
• At the time of the announcement of the Jal Jeevan Mission, only 3.23 crore (16.65%) rural households had tap water connections. Under the Mission, in a short span of less than four years, more than 8.60 Crore rural households have been provided with tap water connections. Thus, as on April 27, 2023, over 11.84 Crore (60.92%) rural households have a functional tap water supply in their homes. Further, Union Budget 2023-24 has allocated a massive Rs. 70,000 Crore for the implementation of the Jal Jeevan Mission.

The tax multiplier is measured using the formula -1(MPC/1-MPC).

The correct answer is - Analyse structural break in data

Key Points

• Analyse structural break in data
• The regression model provided includes interaction terms (e.g., Dt, a dummy variable) and the product of the dummy variable with Yt.
• This setup is used to detect structural breaks, i.e., significant changes in the relationship between variables over time or across subsets of data.
• Structural breaks can occur due to policy changes, economic crises, or other events that alter the underlying data-generating process.
• The interaction terms allow the model to estimate different coefficients for subsets of the data, helping identify and analyze the break points.

Additional Information

• Deseasonalize a time series data
• Deseasonalization removes the seasonal component from data to analyze trends and cycles more effectively.
• This process typically involves using methods like moving averages, seasonal indices, or decomposition techniques rather than regression models with structural terms.
• Analyze the seasonal trend in data
• Seasonal trends refer to periodic fluctuations within a specific time frame (e.g., monthly sales patterns).
• While regression can capture trends, specialized time series models such as SARIMA or decomposition techniques are more commonly employed for this purpose.
• Analyse piecewise linear relationship in data
• Piecewise linear relationships are analyzed using segmented regression or spline models.
• The provided regression model focuses on detecting structural changes, not explicitly modeling piecewise linear relationships.

The correct answer is United National Development Programme. 

Key Points

• The Human Development Report is published annually by the United Nations Development Programme (UNDP). This report provides comprehensive data about global poverty, literacy, education, lifespan, and other factors as a way to measure and compare overall human development across different countries.
• The United Nations Development Programme (UNDP) was established on November 22, 1965.
• The International Monetary Fund (IMF) is an international organization headquartered in Washington, D.C., United States. It was established in 1944 at the Bretton Woods Conference and formally created in 1945. The IMF's primary goal is to ensure the stability of the international monetary system—the system of exchange rates and international payments that enables countries (and their citizens) to transact with one another.
• World Bank is an international organization dedicated to providing financing, advice, and research to developing nations to aid economic advancement.
• Headquaters: Washington D.C.
• Established: July 7, 1944 Bretton Woods, Conference.

• Headquaters: Manila, Philippines

The correct answer is when number of beneficiaries is large and exclusion of any one of them is impossible.

Key Points

• The free rider problem is an economic concept of a market failure that occurs when people are benefiting from resources, goods, or services that they do not pay for. If there are too many free riders, the resources, goods, or services may be overprovided.
• ​Public Goods and the Free Rider Problem
• Public goods commonly face a free rider problem due to the two characteristics of a public good:
• Non-rival: Consumption of the good or service by one individual does not reduce the availability of the good to others.
• Non-excludable: It is impossible to prevent other consumers from consuming the good or service
• The Free-rider problem occurs in situations where individuals can benefit from a resource, good, or service without paying for it, leading to under-provision or depletion of that resource.
• Answer:C. When the number of beneficiaries is large and exclusion of any one of them is impossible:Non-excludability: It is difficult or impossible to exclude individuals from using the good. This means that once the good is provided, it is available to all, and no one can be effectively excluded from its use. For example, national defense or clean air.Non-rivalry: One person’s use of the good does not reduce its availability to others. For instance, when one person enjoys a fireworks display, it does not prevent others from enjoying it as well.Because of these characteristics, individuals may choose not to contribute to the cost of providing the good, knowing they can still benefit from it without paying. This behavior leads to the Free-rider problem, where everyone relies on others to pay for the provision of the good, resulting in it being underfunded or not provided at all.

The correct answer is - ∞ to + ∞.

Key Points

• In a logit model, the logit (L) of a probability (Pi) is calculated as the natural logarithm of the odds ratio, which is given by Pi / (1 - Pi).
• As Pi goes from 0 to 1 (exclusive), the logit L varies from negative infinity to positive infinity. Specifically:
• When Pi approaches 0, the logit L approaches negative infinity.
• When Pi approaches 1, the logit L approaches positive infinity.
• Therefore, the logit function maps probabilities from the (0, 1) interval to the entire real line (-∞ to +∞)

Augmented Dickey - Fuller test is used to test stationary of a time series in the presence of correlated error term.

Key Points

• In statistics, an augmented Dickey–Fuller test (ADF) tests the null hypothesis that a unit root is present in a time series sample.
• The alternative hypothesis is different depending on which version of the test is used, but is usually stationarity or trend-stationarity.
• It is an augmented version of the Dickey–Fuller test for a larger and more complicated set of time series models.

The correct answer is The benefit principle.

Key Points

• The Benefit Principle of taxation asserts that those who receive more benefits from government programs should pay more taxes to support these programs. Accordingly, in the case of tolls, drivers who use toll roads, and thus benefit from them, and the ones who pay for that usage via toll fees.
• Horizontal Equity: If everyone who uses the toll road pays the same fee, it can reflect horizontal equity in that people in the same economic situation are treated equally.
• Vertical Equity (which argues that those with a greater ability to pay, i.e., wealthier individuals, should pay more) or.
• Tax Progressivity (where the tax rate increases as the taxable amount increases),
• unless the toll fee is variable based on the type of vehicle or time of day, potentially correlating with the ability to pay. In the general case, tolls are flat fees regardless of the driver's income or wealth, which might be seen as regressive rather than progressive.

The correct answer is Uruguay

Key Points

• The World Trade Organization (WTO) is an international body that regulates and facilitates international trade between nations. Its main function is to ensure that trade flows as smoothly, predictably, and freely as possible.
• World  Trade Organization was founded on  1 January 1995, but its trading system is half a century older. Since 1948, the General Agreement on Tariffs and Trade (GATT) has provided the rules for the system.

Kydland and Prescott.

Key Points 

Time inconsistency refers to the following idea: • the government has a policy rule; • the people make commitments, based on an expectation of continuation of the policy rule; • later, the government can benefit society by changing its policy rule, taking advantage of the commitments made by the people.

The correct answer is 'economy'

Key Points

• Value - Trade Ratio:
• The Value - Trade ratio is a metric used to measure the volume of trade relative to the size of a country's economy.
• This ratio is important as it indicates how much of a country's economic activity is generated through trade.
• A higher Value - Trade ratio implies that a significant portion of the economy is engaged in international trade, which can be a sign of economic openness and integration into the global market.
• This ratio helps in assessing the impact of trade policies and economic strategies on a country's overall economic performance.

Additional Information

• Market:
• The term "market" refers to the arena in which buyers and sellers interact to exchange goods and services. It does not specifically relate to the size of the economy when considering trade volume.
• While market size can influence trade, it is the broader economy that provides the context for understanding the Value - Trade ratio.
• Market and Economy:
• The combination of both market and economy is not specifically captured by the Value - Trade ratio. This ratio is more directly related to the size of the economy rather than the market alone.
• Focusing on the economy provides a clearer picture of how trade affects the overall economic activities of a country.

"Under-developed countries are the slums of the world economy", is a statement given by Cairncross.

The correct answer is - A → III, B → IV, C → I, D → II

Key Points

• A → III. Price of Risk
• The extra risk that an investor must incur to enjoy a higher expected return is referred to as the Price of Risk.
• Investors expect to be compensated for taking on additional risk, which is the fundamental concept behind the price of risk.
• B → IV. Endowment Effect
• The Endowment Effect is a cognitive bias where individuals tend to value an item more when they own it than when they do not.
• This effect often leads to people overvaluing their possessions, even if they would not have paid that much for the item initially.
• C → I. Risky Asset
• A Risky Asset provides an uncertain flow of money or services to its owner because the returns are not guaranteed.
• Examples of risky assets include stocks and bonds, which carry different levels of risk depending on market conditions.
• D → II. Moral Hazard
• Moral Hazard occurs when one party's actions, which are unobserved by others, affect the likelihood of a specific event or payment, often in situations like insurance policies.
• It refers to situations where the behavior of the insured party is influenced by the knowledge that they are protected from the full consequences of their actions.

Additional Information

• Price of Risk
• Price of risk refers to the compensation an investor demands for taking on additional risk. It is the difference between the return of a risky asset and a risk-free asset.
• Higher risk generally requires higher returns as compensation to the investor.
• Endowment Effect
• The Endowment Effect is a bias that affects the perceived value of an owned object compared to an identical one that is not owned. It influences decision-making and consumer behavior.
• Risky Asset
• Risky assets are investments that have uncertain returns. Common examples include stocks, commodities, and currencies.
• The uncertainty in returns is what makes them risky, and investors require compensation for bearing that risk.
• Moral Hazard
• Moral hazard is a situation where one party to a transaction can affect the risk taken by another party without bearing the full consequences of that risk.
• This is a common issue in insurance and financial markets, where the insured party may take on riskier behavior because they do not bear the full cost of their actions.

A - I, B - IV, C - III, D - II is the right answer. 

Key Points

• The Phillips curve is an economic theory that inflation and unemployment have a stable and inverse relationship. Developed by William Phillips, it claims that with economic growth comes inflation, which in turn should lead to more jobs and less unemployment
• Taxable Capacity means the maximum capacity of the people of a country to bear the burden of taxation without much hardship. It is nothing but the maximum limit that a government can tax the people- Findlay Shirras
• The life-cycle hypothesis (LCH) is an economic theory that describes the spending and saving habits of people over the course of a lifetime. The theory states that individuals seek to smooth consumption throughout their lifetime by borrowing when their income is low and saving when their income is high.
• The concept was developed by economists Franco Modigliani and his student Richard Brumberg in the early 1950s.

A - III, B - I, C - IV, D - II is the right answer. 

Key Points

• Tobit Model - When your regression model involves an interaction term, it is advisable to use a centered score regression model. It is because this transformation can yield a proper interpretation of the data, and also make the scales of the dependent and independent variables comparable.
• A probit model-  a type of regression where the dependent variable can take only two values, for example married or not married. The word is a portmanteau, coming from probability + unit.
• A distributed lag model - a model for time series data in which a regression equation is used to predict current values of a dependent variable based on both the current values of an explanatory variable and the lagged (past period) values of this explanatory variable.
• The partial adjustment model- has been used in many areas of applied economics as a description of optimal behavior in the face of adjustment costs. The model requires a specification of how expectations are formed; for example static or adaptive expectations are frequently specified.

The correct option is 'A - III, B - I, C - IV, D - II'.

Key Points

• Two-Variable Linear Regression Model:
• A two-variable linear regression model explains the relationship between a dependent variable (γ) and an independent variable (X) through a linear equation.
• γ = β1 + β2X:
• This equation represents a simple linear regression where β1 is the intercept and β2 is the slope coefficient.
• In this context, elasticity is represented by β2(X / M), which indicates the responsiveness of γ to changes in X proportionate to the mean value M.
• In γ = β1 + β2X:
• This equation is a semi-logarithmic model where the dependent variable (γ) is logarithmically transformed.
• Here, elasticity is represented by β2X, showing how percentage changes in γ are related to changes in X.
• γ = β1 + β2 ln X:
• This equation is another form of a semi-logarithmic model where the independent variable (X) is logarithmically transformed.
• Elasticity in this model is represented by β2(1 / γ), indicating how changes in γ respond to changes in X inversely proportional to γ.
• In γ = β1 + β2 ln X:
• This equation represents a double-logarithmic model where both the dependent and independent variables are logarithmically transformed.
• In this context, elasticity is given by β2, showing a constant proportional change in γ with respect to proportional changes in X.

Additional Information

• Elasticity:
• Elasticity measures how one variable responds to changes in another variable, typically expressed as a percentage.
• In regression models, elasticity helps understand the sensitivity of the dependent variable (γ) to changes in the independent variable (X).
• Different functional forms of regression models capture different types of elasticity, providing insights into the relationship between variables.

Therefore the correct pairing is:

A - III: γ = β1 + β2X - β2(X / M)

B - I: In γ = β1 + β2X - β2X

C - IV: γ = β1 + β2 ln X - β2(1 / γ)

D - II: In γ = β1 + β2 ln X - β2

A - II, B - I, C - III, D - IV is the right answer.

• Typical examples include tourism, education, and healthcare services availed abroad.
• Mode 3 – Commercial Presence (C - II)
• This mode involves the establishment of a business or subsidiary in another country to provide services.
• It is characterized by foreign direct investment (FDI) in the service sector.
• Examples include foreign banks, telecom companies, or insurance firms setting up branches in another country.
• Mode 4 – Movement of Natural Persons (D - III)
• This mode refers to the temporary movement of individuals across borders to supply services.
• It includes professionals such as consultants, doctors, engineers, and IT experts providing services abroad for a limited period.

 Key Points​

• To determine the chronological sequence of the implementation of various taxes in India, we need to examine the years each tax was introduced. This process is somewhat similar to organizing historical events, much like you would do while preparing notes on economic systems or educational reforms.
• Income Tax: The Income Tax Act was enacted in 1961 and came into effect on 1^st April 1962. Income tax has been a significant part of India's tax system since its implementation.
• Expenditure Tax: The Expenditure Tax Act was introduced in 1987. This tax aimed to levy charges on expenditure incurred on certain specified items.
• Service Tax: Service Tax was introduced in 1994. Initially, it applied to a limited number of services but was gradually expanded to cover most services.
• State VAT (Value Added Tax): State VAT was implemented starting in 2005. This tax replaced the earlier sales tax and aimed to create a more efficient and transparent system for state-level indirect taxes.
• Goods and Services Tax (GST): GST was implemented on 1^st July 2017. This tax subsumed most of the indirect taxes, including VAT, service tax, and excise duty, aiming to unify the tax system across India.
• So, the correct chronological sequence is D, B, A, C, E

The correct answer is - A, E, D, C, B

Key Points

• Government's Role in Treasury Bills
• The government is the sole issuer of T-bills in India, and they are used primarily for financing the budgetary deficit.
• T-bills are sold at a discount to face value and redeemed at par value at maturity.

The correct answer is Statement I is correct but Statement II is incorrect.

Key Points

• The contract curve in economics represents the set of efficient combinations of goods, where it's impossible to find a different allocation that both parties would prefer. This concept comes from the Edgeworth Box, a popular graphical representation in general equilibrium theory.
• The contract curve reflects different allocations that are Pareto efficient, meaning you can't make one individual better off without making at least one other individual worse off. But this doesn't necessarily mean that the resources are equally distributed among individuals or that all individuals have the same level of welfare.

For instance, you might have a Pareto efficient point on the contract curve where one individual has a lot of both goods and the other has very little. That's Pareto efficient because you can't give more to the person with less without taking away from the person with more. But it's not equal – you could say one person is better off in that situation.

The correct answer is '(A) is true but (R) is false'

Key Points

• Assertion (A): The low-income countries are far more likely to borrow money to finance their public sector expenditure.
• Low-income countries often have limited internal resources and revenues, making it necessary for them to seek external financial assistance to fund their public sector projects and services.
• Borrowing is a common practice among these countries to bridge the gap between their expenditures and revenues, especially for infrastructure development, healthcare, and education.
• International financial institutions like the World Bank and International Monetary Fund (IMF) often provide loans to these countries under various terms and conditions.

Additional Information

• Reason (R): Governments need not repay their loans, along with interest payment.
• This statement is false. Governments are typically required to repay the loans they receive, along with the agreed-upon interest, unless specific debt relief programs or restructuring agreements are in place.
• Failure to repay loans can lead to a debt crisis, affecting the country's credit rating and its ability to secure future funding.
• Debt relief initiatives, such as those from the IMF and World Bank, aim to provide struggling nations with more manageable repayment terms but do not imply that loans need not be repaid at all.

The correct answer is Both Statement I and Statement II are true.

Key Points

• In supply-side fiscal policy, tax cuts, lower interest rates, and deregulation help foster increased production.
• Supply-side fiscal policy was formulated in the 1970s as an alternative to Keynesian, demand-side policy.
• Privatization is indeed the process of transferring ownership or control of state-owned assets to private entities, such as individuals or corporations. The primary goals of privatization are often as you mentioned to increase competition, productivity, and efficiency in the economy.

The correct answer is 'C, B, E, A, D'.

Key Points

• Bank Rate (C):

• This rate is a critical tool for controlling inflation and managing the country's economic stability through liquidity adjustments.
• Standing Deposit Facility rate (E):
• The Standing Deposit Facility (SDF) rate is relatively new and allows the RBI to absorb liquidity from the banking system without needing collateral. As of December 2022, the SDF rate was 6.00%.
• This facility is part of the RBI's liquidity management framework and aids in stabilizing short-term interest rates.
• Cash Reserve Ratio (A):
• The Cash Reserve Ratio (CRR) is the percentage of a bank's total deposits that must be kept with the RBI as reserves. As of December 2022, the CRR was 4.50%.
• While CRR is not an interest rate, it plays a crucial role in ensuring liquidity and financial stability in the banking system.
• Reverse Repo Rate (D):
• The Reverse Repo Rate is the rate at which the RBI borrows funds from commercial banks. As of December 2022, the Reverse Repo Rate was 5.75%.
• This rate is used primarily to manage liquidity in the economy and is typically lower than the Repo Rate.

The correct answer is 'B, D, E, A, C'

• Milton Friedman’s contributions to monetarism came later, emphasizing the importance of controlling money supply for economic stability.

The correct answer is Both Statement I and Statement II are true.

Key Points

• High-interest rates can lead to a larger portion of the nation's Gross National Product (GNP) being committed to interest payments on government debt. This payment, in turn, is financed through taxation, which can impose a deadweight loss. Deadweight loss refers to the lost economic efficiency when the equilibrium for a good or service is not achieved, in this case, because taxation has diverted resources away from more productive uses.
• Crowding-out effect happens when government spending increases interest rates, which leads to a reduction in private investment that offsets the increase in government spending. A rising rate of interest payment in the budget means that more of the budget is being dedicated to paying off interest rather than being spent on other public programs. This reduction in government spending on public programs is the crowding-out effect.

The correct answer is D, A, B, C, E. 

Key Points

• Gross Value Added (GVA)

• This is the first stage where the Budget is formally presented to the Legislative Assembly by the Finance Minister.
• It includes the financial statement of the government for the upcoming fiscal year.
• General Discussion:
• After the presentation, a general discussion on the Budget takes place.
• Members of the Legislative Assembly debate the overall Budget proposals without going into details.
• Appropriation Bill:
• Following the general discussion and voting on demands, the Appropriation Bill is introduced.
• This bill authorizes the government to withdraw funds from the Consolidated Fund of India to meet the expenditure.
• Finance Bill:
• After the Appropriation Bill, the Finance Bill is introduced.
• It includes the government's taxation proposals and other financial measures.
• Voting on the Demand for Grants:

Key Points

• The root cause of the crash of the knowledge economy is the intellectual monoplies, i.e. the huge protection inherent to Intellectual Property Rights.
• It is evident from statement - "U. Pagano and M.A. Rossi (2009) have advanced a hypothesis that states that, 'the crash of the knowledge economy is due to the intellectual monopolies, i.e. the huge protection inherent to Intellectual Property Rights (IPRs)."

Key Points

• The authors have stated - the institutions, which are facilitating IPRs are responsible for the crash.
• It is evident from statement from passage.

The IPRs have raised the cost of investments for countries that had neither abundant cheap labour nor high amount of IPR resources, hence it acted as a super tariff.

Key Points

• According to the authors, IPRs have acted as 'super - tariffs' as they have raised the cost of investment for countries that had neither abundant cheap labour nor high amounts of IPR resources. The IPRS may have subsequently exerted negative effect even on IP (Intellectual Property) rich firms or the conflicting rights of the firm may affect each other's investments and result in a situation of a savings glut.

The IPRs have given rise to conflicting rights for different firms, which has affected the volume of investment negatively and resulted in a situation of a savings glut. 

Key Points

• The IPRS may have subsequently exerted negative effect even on IP (Intellectual Property) rich firms or the conflicting rights of the firm may affect each other's investments and result in a situation of a savings glut.
• Therefore, the authors suggested - "if intellectual monopolies are one of the causes of the crash, the remedies should not only focus on monetary policy, financial regulation or even on standard Keynesian policies, rather regulation should be made to decrease the level of intellectual monopolization of economy".

The recovery of the knowledge economy from the crisis can be achieved through the regulations, which can decrease the level of intellectual monopolisation (IPRS) in the economy.

Key Points

• Therefore, the authors suggested - "if intellectual monopolies are one of the causes of the crash, the remedies should not only focus on monetary policy, financial regulation or even on standard Keynesian policies, rather regulation should be made to decrease the level of intellectual monopolization of economy".
• The policy measures they propose, however, aimed at redressing the balance between public and private knowledge, would not only have strong short - run super - multiplicative effects but would have long - run benefits as well.

• W. Arthur Lewis: Theory of Economic Growth

The correct answer is 'Factor substitutions and technological advances can alleviate resource scarcities.'

Key Points

• Malthusian Perspective on Population:
• The Malthusian theory, proposed by Thomas Malthus, suggests that population growth is potentially exponential while the growth of the food supply or other resources is linear.
• Malthus argued that without control, population growth would lead to resource depletion, resulting in poverty and famine.

Additional Information

• Human Population Growth:
• According to Malthus, human population will invariably grow where the means of subsistence increase, as increased resources reduce the mortality rate and allow for larger families.
• Fixed Amount of Land:
• Malthus believed that the total amount of land available for agriculture is immutably fixed, meaning that there is a finite limit to how much food can be produced.
• Food Availability and Population Growth:
• The growth of the population is limited by the amount of food available for subsistence. If food supply cannot keep up with population growth, it results in famine, disease, and mortality.
• Technological Advances:
• Malthus did not account for factor substitutions and technological advances in his theory. These can significantly alleviate resource scarcities by increasing agricultural productivity and finding alternative resources.

The correct answer is All of the above.

Key Points

• Ensuring that for each firm, the marginal abatement cost is equal to the marginal damage from pollution - This is often known as the Pigovian condition where the optimal amount of pollution occurs where the social cost equals the private cost.
• Achieving equality of marginal abatement costs across polluters - This is important to ensure efficiency and fairness. If two firms have different costs of reducing pollution (marginal abatement costs), there's potential for overall cost savings if the firm with the lower abatement cost does more of the reducing.
• Minimising the total cost of the externality to the society - The overall objective of any environmental policy is to reduce the negative impacts (externalities) of pollution on society, and do so in a way that minimizes the total cost, including both the cost of abatement and the cost of the remaining pollution

The correct answer is 'It is an amoral concept'

Key Points

• Externality:
• An externality is an economic concept referring to a cost or benefit incurred by a third party who did not choose to incur that cost or benefit.
• Externalities can be positive or negative and occur due to production or consumption activities affecting third parties.
• Examples include pollution (negative externality) or education (positive externality).
• Amoral Concept:
• Externalities are considered amoral because they do not inherently involve moral judgments about the actions causing them.
• The focus is on the economic impact rather than the ethical implications of the actions.
• Policymakers address externalities to correct market failures, not to pass moral judgment on the activities.

Additional Information

• Human Interactions:
• Externalities are directly related to human interactions since they arise from economic activities involving people.
• Consumer Sovereignty:
• Externalities are not tied to consumer sovereignty, which is the idea that consumers' preferences dictate the production of goods and services.
• Externalities often result from production processes and affect parties not involved in the market transaction.
• Judgements of Right and Wrong:
• While externalities can have ethical implications, the concept itself is not based on higher order judgments of right and wrong.
• It focuses on unintended economic impacts and the need for policy intervention to address market failures.

The correct answer is Growth in poorer nations would actually be self-defeating. 

Key Points

• The term 'Immiserising growth' was coined by the Indian economist Jagdish Bhagwati in 1958.
• 'Immiserizing growth' is a concept in economics that suggests growth in poorer nations may lead to a situation where the overall welfare or well-being of the nation decreases despite economic growth. In simpler terms, it means that the negative consequences of economic growth, such as increased debt or unfavorable terms of trade, may outweigh the positive impacts, causing a decline in the overall standard of living.
• This theoretical situation happens when a country's economic growth leads to a decline in its terms of trade. The country produces and exports more, but the prices of its exports fall relative to the prices of its imports. This can cause the total purchasing power of a country to decrease rather than increase.

Key Points

• In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable.
• The parameter ���

 is the mean or expectation of the distribution (median/mode), while the parameter Unknown node type: strongUnknown node type: strongUnknown node type: strong

 is its standard deviation

• The variance of the distribution is �2�2�2

. A random variable with a Gaussian distribution is said to be normally distributed, and is called a normal deviate.

Additional Information

• A normal distribution is sometimes informally called a bell curve. However, many other distributions are bell-shaped (such as the Cauchy, Student's t, and logistic distributions)

• Referring to the probability bell curve diagram

• Distance from the mean ordinates in terms of ± σ at Z = ± 1.96 is 0.95 is true

• Distance from the mean ordinates in terms of ± σ at Z = ± 2.0 is 0.9544 is true.

• Distance from the mean ordinates in terms of ± σ at Z = ± 3.0 is 0.9973 is true

Key Points The assumptions of Classical Linear Regression Model are :

• The regression model is linear in the parameters
• Zero mean value of disturbance Ui
• The number of observations must be greater than the number of parameters to be estimated

A,  B and C is correct answer.

Key Points

• Statement 1 is  A ∩ Ø = Ø is correct. The intersection of any set (A) with the empty set results in the empty set. Since the empty set has no elements, there are no elements to be shared between (A) and (empty set).
• Statement 2 is A ∩ (B ∪ C) = (A ∩ B) ∪ (A ∩ C) is correct.
• This is known as the Distributive Law of sets. It states that if you have a set (A) intersected with the union of sets (B) and (C), you can distribute (A) across the union. As a result, it becomes the union of two intersections: (A) with (B) and (A) with (C).
• Statement 3 A ∩ A' = Ø is correct. (A') denotes the complement of (A), meaning it contains all the elements not in (A). The intersection between a set and its complement is always the empty set, as they have no elements in common by definition.
• Statement 4 B - A = B' ∩ A' This statement is False. The correct relationship for the difference between two sets (B) and (A) ((B - A)) can be expressed using the intersection of (B) with the complement of (A), not as stated. The correct formulation is (B - A = B $\cap A$').
• (A ∪ B)' = A' ∪ B' is incorrect. It negates De Morgan's law

Key Points

• Revenue yield should be adequate:
• This statement is correct.
• A good tax system should ensure that the revenue generated is sufficient to meet the government's expenditure needs and support public services.
• Administrative and compliance cost of tax should be as minimum as possible:
• This statement is correct.
• Minimizing the administrative and compliance costs of a tax system is crucial for efficiency. Lower costs make the system more effective and less burdensome for taxpayers and the government.
• Tax system should not permit scope for tax leakage and tax evasion:
• This statement is correct.
• A good tax system should be designed to minimize opportunities for tax evasion and leakage, ensuring that taxes are collected fairly and effectively.
• Tax system should be so that different income groups of people pay tax equally:
• This statement is incorrect.
• A good tax system should be progressive, meaning that higher-income groups should pay a higher percentage of their income in taxes compared to lower-income groups, to promote fairness and equity.
• Tax should be chosen to maximise interference with market efficiency:
• This statement is incorrect.
• A good tax system should minimize interference with market efficiency, allowing markets to function smoothly and efficiently without unnecessary distortions.

Additional Information

• Features of a Good Tax System:
• Equity: A good tax system should be equitable, meaning that it should distribute the tax burden fairly among different groups, typically through progressive taxation.
• Efficiency: The tax system should be efficient, causing minimal distortion to economic decisions and market functioning.
• Simplicity: The tax code should be simple and easy to understand to reduce compliance costs and administrative burdens.
• Certainty: Taxpayers should be certain about how much tax they owe and the timing of tax payments, ensuring stability in the tax system.
• Flexibility: The tax system should be flexible enough to adapt to changing economic conditions and fiscal needs.
• Importance of Minimizing Tax Evasion and Leakage:
• Reducing tax evasion and leakage ensures that the government collects the revenues it is due, allowing for better funding of public services and infrastructure.
• It also promotes fairness in the tax system, as all taxpayers are required to pay their fair share.

The correct answer is Stage - III.

Key Points

• The Product cycle model is a marketing concept that describes the stages a product goes through from when it first enters the market until it is removed from the market.
• The stages typically include introduction, growth, maturity, and decline.
• Introduction Stage: This is the period of slow sales growth as the product is introduced in the market. Profits are nonexistent in this stage because of the heavy expenses of product introduction and marketing efforts.
• Growth Stage: A period of rapid market acceptance and substantial profit improvement often characterizes the growth stage. The company begins to recognize substantial profit and invest more in promotional activities to maximize the potential of this stage.
• Maturity Stage: This is a period of slow sales growth because the product has achieved acceptance by most potential buyers. The aim here is to prolong the life cycle of the product, maintain market share and defend from competitors.
• Decline Stage: The decline stage is characterized by diminishing market interests and sales drop. The reason could be technological advances, shifts in consumer tastes, or increased competition. Companies need to decide whether to maintain the product (possibly rejuvenating it) or discontinue it

The correct answer is $T = 1 - \frac{|X - M|}{X + M}$ 

Key Points

• The intra-industry index (T) measures the level of intra-industry trade. It is calculated as the ratio of the trade within a particular industry to the total trade of that industry. The formula for the intra-industry index (T) is:
• $[ T = \frac{{\text{{Intra-Industry Trade}}}}{{\text{{Total Trade of the Industry}}}} \times 100$
• Intra-industry trade refers to the exchange of similar types of goods or services between countries within the same industry. The index helps assess the extent to which a particular industry engages in intra-industry trade as opposed to inter-industry trade.

B, D and E only

Key Points

• The loanable funds doctrine is a theory of the market interest rate. According to this approach, the interest rate is determined by the demand for and supply of loanable funds. The term loanable funds includes all forms of credit, such as loans, bonds, or savings deposits.
• The loanable funds doctrine extends the classical theory, which determined the interest rate solely by saving and investment, in that it adds bank credit.
• The total amount of credit available in an economy can exceed private saving because the bank system is in a position to create credit out of thin air. Hence, the equilibrium (or market) interest rate is not only influenced by the propensities to save and invest but also by the creation or destruction of fiat money and credit.
• If the bank system enhances credit, it will at least temporarily diminish the market interest rate below the natural rate.
• Wicksell had defined the natural rate as that interest rate which is compatible with a stable price level. Credit creation and credit destruction induce changes in the price level and in the level of economic activity. This is referred to as Wicksell's cumulative process.

Key Points

• A current account surplus means an economy is exporting a greater value of goods and services than it is importing. A country with a current account surplus will have a deficit on the financial/capital account. i.e. a country with a current account surplus will have surplus foreign exchange it can use to invest in other countries.
• There is no hard and fast rule about what will happen if a country has a current account surplus. It depends on the size of the current account and the reasons for the current account surplus.
• In theory, you could expect a current account surplus (X-M) to boost employment because it is indicative of higher domestic demand.
• Currency appreciation is very likely to happen because of stronger domestic currency against foreign currency.
• This will automatically lead to higher standard of living for domestic residents.

Key Points

• Probability is used to denote the happening of a certain event, and the occurrence of that event, based on past experiences.
• The mathematical expectation is the events which are either impossible or a certain event in the experiment.
• Probability of an impossible event is zero, which is possible only if the numerator is 0. Probability of a certain event is 1 which is possible only if the numerator and denominator are equal.

Additional Information  

• Mathematical expectation, also known as the expected value, which is the summation of all possible values from a random variable.
• It is also known as the product of the probability of an event occurring, denoted by P(x), and the value corresponding with the actually observed occurrence of the event.
• For a random variable expected value is a useful property. E(X) is the expected value and can be computed by the summation of the overall distinct values that is the random variable.
• E(X)= Σ (x1p1, x2p2, …, xnpn),

where, x is a random variable with the probability function, f(x),

p is the probability of the occurrence,

and n is the number of all possible values.

• Properties of Mathematical Expectation:

• E(X+Y)=E(X)+E(Y)

• E(XY)=E(X)E(Y)

• E(a+f(X))=a+E(f(X)),

• E(aX+b)=aE(X)+b,

• E(∑aiXi)=∑ ai E(Xi)

Where, ai, (i=1…n) are constants.

A,D and E is correct answer. 

Key Points

• Expansionary monetary policy works by expanding the money supply faster than usual or lowering short-term interest rates.
• It is enacted by central banks and comes about through open market operations, reserve requirements, and setting interest rates.
• Expansionary fiscal policy includes tax cuts, transfer payments, rebates and increased government spending on projects such as infrastructure improvements
• For example, it can increase discretionary government spending, infusing the economy with more money through government contracts.

A, C and D only.

Key Points

• Independent events are those events whose occurrence is not dependent on any other event.
• For example, if we flip a coin in the air and get the outcome as Head, then again if we flip the coin but this time we get the outcome as Tail.
• In both cases, the occurrence of both events is independent of each other. It is one of the types of events in probability.
• If A and B are two independent events, then

P(A ∩ B) = P(B) .P(A)

The correct answer is A, B, C and E only.

Key Points 

• The demand curve of an oligopolistic market is indeterminate:  This is due to the interdependent nature of firms in an oligopoly. Each firm's demand depends not only on its own prices but also on the prices of its competitors. Also, the reactions of competitors to a firm's actions are uncertain, making the demand curve less defined.
• There is a possibility of only two sellers:  An oligopoly can have a few dominant firms controlling the market. A duopoly, which is a specific type of oligopoly with exactly two sellers, is a possible scenario in an oligopoly.
• The product may be homogenous or differentiated:  In an oligopoly, the firms can either sell identical products (like in the petroleum industry) or differentiated products (like in the auto industry).
• There is an importance of advertisement cost: specially in oligopolies with differentiated products, advertisement and branding can play a significant role to stand out and increase demand.
• There is free entry into and free exit out of the market: One characteristic of oligopolistic markets is the existence of barriers to entry. These could include high startup costs, control over a key resource, or regulations that prevent easy entry into the market. Therefore, free entry and exit is not typical.
• So, options A, B, C, and E are true for an oligopolistic market
