Question 1

Suppose that,as a result of a decrease in the market supply of labor,the wage rate has risen 10%.After adjusting its employment level,a firm finds its total wage bill has decreased.This occurrence indicates that the firm's labor demand:

Accepted Answer

If the total wage bill has decreased after the wage rate has risen 10%, it means that the firm has either decreased its employment level, decreased the number of hours worked, or replaced some workers with other factors of production. This indicates that the firm's labor demand is responsive to changes in the wage rate, and therefore, elastic over this range of wages. If the demand were inelastic, the firm would have increased its total wage bill despite the rise in the wage rate because it would not have been able to reduce the amount of labor it employed. Therefore, option B is the best choice.

Question 2

Since 1980,the number of jobs in manufacturing has:

Accepted Answer

The decrease in manufacturing jobs since 1980 is partly due to the increased reliance on workers from temporary help agencies, among other factors such as automation and globalization. This shift allows companies to be more flexible with their workforce, often resulting in fewer traditional, long-term manufacturing positions.

Question 3

Suppose that the decline in prices of personal computers has reduced the demand for labor at a particular firm.We may conclude that at this firm:

Accepted Answer

If the decline in prices of personal computers has reduced the demand for labor at a particular firm, it indicates that computers and labor are gross substitutes. This means that the firm can replace labor with computers to produce the same amount of output at a lower cost. If computers and labor were complements, a decline in computer prices would lead to an increase in the demand for labor, as more computers would require more workers to operate them.

Question 4

A union leader told its membership that a wage increase,while resulting in some layoffs,would nonetheless increase the total incomes of its membership.The firm replied that a wage increase would reduce the total incomes of its membership.We can conclude that:

Accepted Answer

The union leader's statement suggests that they believe that a wage increase will lead to job losses, indicating that they think labor demand is inelastic. However, they also believe that the resulting wage increase will more than make up for the job losses in terms of total income for its members, indicating they think labor supply is elastic. The firm's response suggests they think labor demand is elastic - if they believed it to be inelastic, they would expect a wage increase to lead to fewer layoffs but total income staying the same or decreasing. Therefore, the union believes labor demand is inelastic while the firm believes it to be elastic.

Question 5

In the textile industry,industrial robots and assembly line workers are gross substitutes.Accordingly,the drop in the price of robots has:

Accepted Answer

In this scenario, industrial robots and assembly line workers are gross substitutes, meaning that they can easily replace each other in the production process. A drop in the price of robots would make them relatively cheaper compared to assembly line workers, leading to a decrease in the demand for assembly line workers. As a result, choice C, "decreased the demand for assembly line workers," is the best choice.

Question 6

In comparing two otherwise identical industries X and Y,an economist finds that labor demand is more elastic in industry X.Which of the following would support this finding?

Accepted Answer

Labor demand elasticity is often related to the elasticity of product demand. Therefore, industry X may have a more elastic labor demand because product demand in that industry is more elastic than in industry Y. This means that small changes in price result in greater changes in quantity demanded, which in turn requires firms in industry X to adjust their labor demand more frequently.

Question 7

In comparing two otherwise identical industries X and Y,an economist finds that labor demand is less elastic in industry X.Which of the following would support this finding?

Accepted Answer

Labor demand is less elastic in industry X because capital and labor are less easily substituted for one another in X than in Y. This means that even if the wage rate increases in industry X, firms may not be able to substitute capital for labor easily, so the demand for labor will not decrease as much as it would in industry Y where capital and labor are easily substitutable.

Question 8

Which of the following can be predicted to increase the demand for labor?

Accepted Answer

The answer of Which of the following can be predicted...

Question 9

In which industries does the Bureau of Labor Statistics project the fastest employment growth over the next ten years?

Accepted Answer

The Bureau of Labor Statistics projects the fastest employment growth over the next ten years in the industries of health care and computers. This is due to the increasing demand for healthcare services and the continued growth in technology and digitalization of almost all industries.

Question 10

The contingent work force:

Accepted Answer

The contingent work force has grown about 4 times as fast as the rest of the work force over the last two decades. This includes temporary workers, independent contractors, and freelancers who work on a project basis or short-term contracts. It also includes workers who are involuntarily employed part-time. Therefore, option A is the best choice. Option B and C are incorrect as they only consider one type of worker in the contingent workforce. Option D is also incorrect as the contingent workforce has grown, not shrunk, over the years.

Question 11

Skilled labor will benefit from an increase in the wage rate paid to unskilled labor if:

Accepted Answer

The substitution effect refers to the tendency for employers to substitute unskilled labor for skilled labor when the wage rate for unskilled labor increases. The output effect refers to the tendency for employers to increase production when the wage rate for unskilled labor increases. If the substitution effect outweighs the output effect, then skilled labor will benefit from an increase in the wage rate paid to unskilled labor.

Question 12

If energy and unskilled labor are gross complements,an increase in the price of energy will:

Accepted Answer

If energy and unskilled labor are gross complements, an increase in the price of energy will make it more expensive to produce goods that require both inputs. This will lead to a decrease in the demand for unskilled labor, thereby decreasing the unskilled wage.

Question 13

Assume that skilled labor and energy are substitutes in production. An increase in energy prices is then predicted to:

Accepted Answer

An increase in energy prices will increase the cost of production, leading firms to substitute away from energy and towards skilled labor if possible. This is the substitution effect. However, if the increase in energy prices leads to a decrease in output (due to lower profits or higher prices for consumers), the demand for skilled labor may decrease as well due to a decrease in overall production. This is the output effect. If the output effect outweighs the substitution effect, then the demand for skilled labor will decrease. Therefore, the best choice is D.

Question 14

The market wage increases from $9 to $11and the firm responds by reducing its labor force by 16%.The wage elasticity coefficient is:

Accepted Answer

The wage elasticity of demand for labor is calculated as the percentage change in quantity of labor demanded divided by the percentage change in wage. Here, the wage increases by 22.22% (from $9 to $11 is a $2 increase on $9, which is 2/9 = 0.2222 or 22.22%), and the labor force is reduced by 16%. Thus, the elasticity coefficient = -16% / 22.22% = -0.72 (approximately -0.8 when rounded), indicating inelastic demand since the absolute value is less than 1. The negative sign is often omitted when discussing elasticity, focusing on the magnitude.

Question 15

Suppose that,as a result of an increase in the market supply of labor,the wage rate has fallen 10%.After adjusting its employment levels,a firm finds its total wage bill has decreased.This occurrence indicates that the firm's labor demand:

Accepted Answer

When a firm's total wage bill decreases after a wage rate reduction, it indicates that the percentage decrease in the wage rate is not fully compensated by the percentage increase in the quantity of labor employed, suggesting that the firm's labor demand is inelastic over this range of wages. Elastic demand would have resulted in an increase or no change in the total wage bill if the firm hired more workers to offset the lower wage rate.

Question 16

(appendix)An isoquant shows all combinations of:

Accepted Answer

An isoquant is a curve that represents all the combinations of labor and capital that result in the same level of output, making option D the correct answer.

Question 17

(appendix)At the least-cost combination of capital and labor:

Accepted Answer

At the least-cost combination, the marginal rate of technical substitution (MRTS) of labor for capital equals the ratio of the price of labor to the price of capital, ensuring cost minimization for a given level of output.

Question 18

In his comparison of over 100 studies of labor demand,Hamermesh concludes the overall long-run elasticity of labor demand in the United States to be:

Accepted Answer

Hamermesh's conclusion from his comparison of studies indicates that the long-run elasticity of labor demand in the United States is approximately 1.0, meaning that a 1% increase in wages would lead to a 1% decrease in the quantity of labor demanded.

Question 19

Which of the following can be predicted to increase the demand for labor?

Accepted Answer

An increase in product demand will lead to an increase in production which in turn will lead to an increase in the demand for labor.

Question 20

International trade:

Accepted Answer

International trade can lead to an increase in demand for labor in some industries (such as exporting industries) while reducing demand for labor in other industries (such as import-competing industries). This is because international trade changes the composition of the economy, leading to a shift in demand for different types of goods and services, and thereby affecting labor demand in different sectors. However, overall, the impact of international trade on labor demand can be positive if the gains in efficiency and productivity resulting from trade lead to overall economic growth and job creation.
