Which of the following factors does NOT influence the demand for a good?

The cost of production is a determinant of supply, not demand. Demand is influenced by factors such as price of related goods, income, and future expectations.
Sumera Nawaz ECONOMICS   -   Microeconomics

If the demand for a product increases while its supply remains constant, what will happen to the equilibrium price and quantity?

An increase in demand with constant supply will lead to an increase in both equilibrium price and quantity traded.
Sumera Nawaz ECONOMICS   -   Microeconomics

Which of the following statements about elasticity of demand is true?

Elasticity of demand measures how much quantity demanded responds to a change in price. Elastic demand means consumers are sensitive to price changes.
Sumera Nawaz ECONOMICS   -   Microeconomics

Which of the following events would lead to a decrease in the equilibrium price of oranges?

A decrease in the price of a complement to oranges (orange juice) would increase the demand for oranges, leading to a decrease in equilibrium price.
Sumera Nawaz ECONOMICS   -   Microeconomics

If demand is perfectly elastic, what is the value of price elasticity of demand?

Perfectly elastic demand means any change in price results in an infinite change in quantity demanded.
Sumera Nawaz ECONOMICS   -   Microeconomics

When is the price elasticity of supply perfectly inelastic?

Perfectly inelastic supply means the quantity supplied does not change at all in response to changes in price.
Sumera Nawaz ECONOMICS   -   Microeconomics

If both supply and demand increase but the increase in supply is larger, what will happen to equilibrium price and quantity?

When both supply and demand increase, but the increase in supply is larger, the increase in quantity supplied will outweigh the increase in quantity demanded, leading to a decrease in price and an increase in quantity.
Sumera Nawaz ECONOMICS   -   Microeconomics

If the price elasticity of demand is less than 1, it indicates that quantity demanded is not very responsive to changes in price, hence the demand is considered inelastic.
Sumera Nawaz ECONOMICS   -   Macroeconomics

Which of the following is NOT included in the calculation of Gross Domestic Product (GDP)?

Transfer payments are not counted in GDP as they do not represent production of goods and services.
Sumera Nawaz ECONOMICS   -   Macroeconomics

Which of the following measures is used to adjust Gross Domestic Product (GDP) for inflation?

Sumera Nawaz ECONOMICS   -   Macroeconomics

If Gross Domestic Product (GDP) is $10 trillion and Gross National Product (GNP) is $11 trillion, what is the value of net factor income from abroad (NFIA)?

GNP - GDP = NFIA, so $11 trillion - $10 trillion = $1 trillion.
Sumera Nawaz ECONOMICS   -   Macroeconomics

Which of the following transactions would be included in the calculation of Gross Domestic Product (GDP)?

If a country's Gross Domestic Product (GDP) is $800 billion and its Gross National Product (GNP) is $750 billion, what is the value of net factor income from abroad (NFIA)?

GNP - GDP = NFIA, so $750 billion - $800 billion = -$50 billion. Since NFIA is negative, it means the country has a net outflow of income to the rest of the world, so the absolute value of NFIA is $50 billion.
Sumera Nawaz ECONOMICS   -   Econometrics

What is the primary purpose of using Instrumental Variables (IV) in econometrics?

Instrumental Variables (IV) are used in econometrics to address endogeneity problems, which occur when an explanatory variable is correlated with the error term. IVs help in obtaining consistent estimates by providing a source of variation that is correlated with the endogenous explanatory variable but uncorrelated with the error term.
Sumera Nawaz ECONOMICS   -   Econometrics

When is the use of a fixed-effects model preferable to a random-effects model in panel data analysis?

The fixed-effects model is preferable when the individual effects are correlated with the explanatory variables. This model accounts for unobserved heterogeneity by allowing each cross-sectional unit to have its own intercept, thus controlling for time-invariant characteristics.
Sumera Nawaz ECONOMICS   -   Econometrics

Which test is commonly used to detect autocorrelation in the residuals of a regression model?

The Durbin-Watson test is commonly used to detect autocorrelation in the residuals of a regression model. It tests the null hypothesis that there is no first-order autocorrelation in the residuals, with values near 2 indicating no autocorrelation and values approaching 0 or 4 indicating positive or negative autocorrelation, respectively.
Sumera Nawaz ECONOMICS   -   Econometrics

Why is multicollinearity a problem in multiple regression analysis?

Multicollinearity is a problem because it causes the standard errors of the regression coefficients to be inflated, which can lead to less precise estimates and make it difficult to determine the individual effect of each explanatory variable. This reduces the reliability of hypothesis tests.
Sumera Nawaz ECONOMICS   -   Econometrics

How to address heteroskedasticity in a regression model?

Heteroskedasticity can be addressed by applying robust standard errors, which provide consistent standard error estimates even when heteroskedasticity is present. This adjustment ensures that inference drawn from the regression coefficients remains valid despite the presence of non-constant variance in the error terms.
Sumera Nawaz ECONOMICS   -   Managerial Economics

What is the main reason for a firm to engage in price discrimination?

Price discrimination allows a firm to charge different prices to different customers based on their willingness to pay. By doing so, the firm can capture more consumer surplus and convert it into additional revenue, thereby maximizing its overall revenue.
Sumera Nawaz ECONOMICS   -   Managerial Economics

When should a firm continue producing in the short run even if it is incurring losses?

A firm should continue producing in the short run if its total revenue covers variable costs. This is because, in the short run, fixed costs are sunk and must be paid regardless of production. If the firm can cover its variable costs, it minimizes its losses by contributing to fixed costs.
Sumera Nawaz ECONOMICS   -   Managerial Economics

Where is the optimal point of production for a firm operating under perfect competition in the long run?

In the long run, a perfectly competitive firm will produce at the point where marginal cost (MC) equals average total cost (ATC), and this is also where MC equals marginal revenue (MR). At this point, the firm is making normal profit (zero economic profit), as any deviation would prompt market entry or exit, driving profits to zero.
Sumera Nawaz ECONOMICS   -   Managerial Economics

How to determine the profit-maximizing output level for a monopolist?

A monopolist maximizes profit by producing the output level where marginal revenue (MR) equals marginal cost (MC). At this point, the additional revenue from selling one more unit equals the additional cost of producing that unit, maximizing the firm's profit.
Sumera Nawaz ECONOMICS   -   Managerial Economics

Which factor can lead to economies of scale in production?

Economies of scale occur when a firm's per-unit costs decrease as production increases. One way this can happen is through bulk purchasing of raw materials at a discounted rate, which reduces the average cost of inputs and contributes to lower overall production costs.
Fani Warraich ECONOMICS   -   Managerial Economics

Which pricing strategy involves setting a high initial price for a new or innovative product to "skim" segments of the market willing to pay the higher price?

Price skimming involves setting a high initial price for a new or innovative product to capture the maximum consumer surplus from segments of the market willing to pay the higher price. As these segments are exhausted, the price is gradually lowered to attract more price-sensitive customers.
Fani Warraich ECONOMICS   -   Managerial Economics

How to determine the optimal capital structure for a firm according to the Modigliani-Miller theorem without taxes?

According to the Modigliani-Miller theorem without taxes, in an efficient market, the value of a firm is unaffected by its capital structure. The theorem posits that the firm's value is determined by its operating income and the risk of its underlying assets, not by how it is financed.
Fani Warraich ECONOMICS   -   Managerial Economics

Why is the kinked demand curve model used in oligopoly markets?

The kinked demand curve model is used to explain why prices in oligopoly markets tend to be rigid. The model suggests that firms are reluctant to change prices because they expect competitors to match price decreases but not price increases, leading to a kink in the demand curve and resulting in price stability.
Fani Warraich ECONOMICS   -   Managerial Economics

What is the primary characteristic of a Nash Equilibrium in game theory?

A Nash Equilibrium occurs when players choose strategies such that no player can benefit by unilaterally changing their strategy. At this equilibrium, each player's strategy is optimal given the strategies of all other players, leading to no incentive for any player to deviate.
Fani Warraich ECONOMICS   -   Managerial Economics

When analyzing a firm's cost structure, what does the term "economies of scope" refer to?

Economies of scope refer to cost savings that a firm experiences by producing a variety of products. These savings arise when the production of one good reduces the cost of producing another related good, often due to shared resources, technologies, or distribution channels.
