Question 1

In drawing an individual demand curve for a commodity, all but which of the following are kept constant:&#10;A)individual's money income&#10;B)the prices of the related commodity&#10;C)price of the commodity under consideration&#10;D)tastes of the consumer

Accepted Answer

In drawing an individual demand curve, the price of the commodity under consideration is not kept constant; it is the variable that changes to show how quantity demanded varies with price. All other factors (A, B, D) are held constant to isolate the effect of price changes on quantity demanded.

Question 2

When an individual's income rises, when everything else remains the same, his demand for normal goods:&#10;A)rises&#10;B)falls&#10;C)remains the same&#10;D)any of the above is possible

Accepted Answer

When an individual's income rises, the demand for normal goods typically increases because people have more money to spend and are willing to buy more of these goods.

Question 3

When an individual's income falls, when everything else remains the same, his demand for inferior goods:&#10;A)increases&#10;B)decreases&#10;C)remains unchanged&#10;D)cannot say

Accepted Answer

Inferior goods are those goods for which demand increases when income decreases, assuming all other factors remain constant. This is because consumers may switch to less expensive alternatives as their purchasing power declines.

Question 4

When the price of the substitute commodity of X falls, the demand for X:&#10;A)rises&#10;B)falls&#10;C)remains unchanged&#10;D)all of the above is possible

Accepted Answer

When the price of a substitute commodity falls, consumers are more likely to purchase the substitute instead of commodity X, leading to a decrease in the demand for X.

Question 5

If the quantity demanded remains unchanged as the price of the commodity falls, the coefficient of price elasticity of demand is:&#10;A)greater than&#10;B)one equal to one&#10;C)smaller than one&#10;D)zero

Accepted Answer

The coefficient of price elasticity of demand is zero when the quantity demanded remains unchanged as the price of the commodity falls, indicating perfectly inelastic demand.

Question 6

If the income elasticity of demand is greater than one, then the commodity is:&#10;A)necessity&#10;B)luxury&#10;C)inferior&#10;D)non-related commodity

Accepted Answer

The answer of If the income elasticity of demand is...

Question 7

Which of the following is an exception to the law of demand?&#10;A) giffen good&#10;B)normal good&#10;C)superior good&#10;D)all of the above

Accepted Answer

Giffen goods are an exception to the law of demand because as their prices increase, people consume more of them, contrary to what the law of demand would predict. This behavior is typically due to the lack of close substitutes and the fact that these goods take up a significant portion of the consumer's budget.

Question 8

The law of diminishing marginal utility was popularized by:&#10;A)keynes&#10;B)marshall&#10;C)smith&#10;D)samuelson

Accepted Answer

The law of diminishing marginal utility was popularized by Alfred Marshall, a British economist known for his significant contributions to the principles of economics.

Question 9

If the income elasticity of demand for a commodity is found to be 0.4, then the commodity concerned is:&#10;A)luxury&#10;B)necessity&#10;C) giffen's goods&#10;D)independent good

Accepted Answer

Necessity goods have an income elasticity of demand between 0 and 1, indicating that demand increases with income, but at a slower rate than income increases. An elasticity of 0.4 fits this description.

Question 10

Cross elasticity of demand in the case of substitutes:&#10;A)zero&#10;B)negative&#10;C)positive&#10;D)infinity

Accepted Answer

The cross elasticity of demand for substitutes is positive because as the price of one good increases, the demand for its substitute increases.

Question 11

If a small change in price leads to infinitely large change in quantity demanded, then the demand is:&#10;A)perfectly elastic&#10;B)perfectly inelastic&#10;C)elastic&#10;D)inelastic

Accepted Answer

The answer of If a small change in price leads...

Question 17

When there are only few sellers of the commodity, the market is called:&#10;A)monopoly&#10;B)duopoly&#10;C)oligopoly&#10;D)monopsony

Accepted Answer

The answer of If the supply curve of the commodity...

Question 19

From the position of stable equilibrium, the market supply of a commodity decreases, while the market demand remains unchanged, then:&#10;A)equilibrium price falls&#10;B)equilibrium quantity rises&#10;C)both equilibrium price and equilibrium quantity decreases&#10;D)equilibrium price rises, but equilibrium quantity falls

Accepted Answer

The answer of From the position of stable equilibrium, the...
