Document Summary

The price paid for factors affects: the money incomes of households the allocation of resources among different firms and industries the quantities of different resources employed to produce a particular product. The factor demand curve for a competitive firm slopes downward because of: Correct answer: the law of down-sloping demand the law of diminishing returns decreasing returns to scale the reduction in output price required to increase sales. All but one of the following would shift the demand curve for a factor. Correct answer: a change in technology a change in the price of the other inputs used in production a change in the price of the factor a change in the price of the output. A profit-maximizing firm will hire an input up to the point where: the law of diminishing returns no longer holds average cost of production is minimized marginal product begins to fall marginal revenue product equals marginal factor cost.

	True
	False

As the wage rate rises, the marginal revenue product of labor increases.

	True
	False

A competitive firmâs demand for labor always slopes down in the short-run, but may slope upwards or downwards in the long run.

	True
	False

When labor an capital are complements in production, a higher wage will cause a firm to use more capital in the long run.

	True
	False

If labor is a regressive factor, then a firmâs long-run demand for labor may or may not be downward sloping.

	True
	False

The short-run demand curve for labor for a firm in any type of market for its output coincides with

	the upward-sloping portion of the marginal revenue product curve.
	the downward-sloping portion of the marginal revenue product curve.

	the downward-sloping portion of the marginal product curve.
	the marginal labor cost curve.

An increase in the price of labor will, in the short run, cause a competitive firmâs

	marginal cost to increase, the quantity it sells to decrease, and therefore reduce the quantity of labor demanded.
	price of its output to increase, leaving the quantity of labor demanded unchanged.

	marginal revenue product of labor to decrease, and therefore reduce demand for labor.
	marginal revenue product of labor to increase, and therefore increase demand for labor.

Which of the following would cause the firmâs short-run demand curve for labor to shift to the right?

	A decrease in the wage rate.
	An increase in the price of the firmâs product.

	An increase in the rental rate paid to capital.

	labor and capital are substitutes in production.
	labor is a Giffen factor.

When is the law of demand violated for labor? That is, with regards to the law of labor demand, when does an increase in the wage not lead to a reduction in the quantity of labor demanded?

	Never.
	When the substitution and scale effects are in opposition, with the scale effect being the larger.

	When labor is a regressive factor.
	When labor earns zero economic rent.

If the wage rate rises, then the firmâs long-run marginal costs change, which in turn affects the firmâs output level and its employment of labor. This phenomenon is known as

	the substitution effect.
	the scale effect.

	the regressive-factor effect.
	the factor-price effect.

When will the scale effect of a wage increase cause a reduction in the quantity of labor demanded?

	Always.
	When labor is not a regressive factor.

	When labor and capital are substitutes in production.
	When labor and capital are complements in production.

Consider the usual case where a higher wage rate increases a firmsâ marginal costs. In this case, the industryâs demand curve for labor

	contains only substitution effects but no scale effects.
	is horizontal at the going wage rate.

A firmâs revenue minus its factor payments equals

	zero.
	the profits or losses earned by the firm.

	always decreases.

A profit-maximizing price taker will produce at a level where

	the wage equals the marginal product of labor.
	the marginal revenue product of labor equals the price of their output.

	the wage rate equals the price of their output.
	the marginal revenue product of labor equals the wage rate.

If the wage rate is $10 per hour and one worker can produce 2 units of output per hour, then the marginal cost of production is

	$5.
	$10.

	$20.

In the indifference curve budget line model of labor supply,

	labor is measured along the horizontal axis and leisure is measured along the vertical axis.
	labor is measured along the horizontal axis and consumption is measured along the vertical axis.

	consumption is measured along the horizontal axis and labor is measured along the vertical axis.
	consumption is measured along the horizontal axis and leisure is measured along the vertical axis.

In the indifference curve budget line model of labor supply, the slope of the indifference curve is used to measure

	the wage rate.
	laborâs marginal product.

	the workerâs nonlabor income.
	the marginal value of leisure.

If a worker has chosen a quantity of labor where the marginal value of leisure exceeds the wage rate, she would be better off by

	choosing less leisure.
	providing fewer hours of labor.

	providing more hours of labor.
	staying at this combination of labor and consumption.

When there is an increase in the wage rate there will be

	both a substitution effect and an income effect.
	only a substitution effect.

	only a substitution effect.
	either a substitution effect or an income effect.

When the wage rate rises, the substitution effect leads a worker to

	increase consumption while the income effect leads to a decrease in consumption.
	decrease consumption while the income effect leads to an increase in consumption.

	increase consumption, as does the income effect.
	substitution sleep for other leisure.

Consider the indifference curve budget line model of labor supply, and assume consumption and leisure are both normal goods. A higher wage rate would result in

	more consumption and less leisure.
	a reduction in the workerâs marginal value of leisure.

	reduced consumption if the income effect is larger than the substitution effect.
	increased labor only if the substitution effect outweighs the income effect.

When the wage rate rises, a worker chooses to replace some leisure hours with work hours, even if he would remain equally well off. This phenomenon is known as

	compensating differential.
	the income effect.

	the substitution effect.
	intertemporal substitution.

Which of the following will shift a workerâs labor supply curve to the left?

	Higher nonlabor income.
	A lower wage rate, assuming the substitution effect dominates the income effect.

	New machinery that substitutes for labor and lowers its marginal product.
	A decrease in the marginal value of leisure.

Which of the following would cause a rightward shift in the labor demand curve?

	Manna from heaven.
	A rise in the wage rate.

	A rise in workersâ marginal productivity.
	A decline in workersâ nonlabor incomes.

When some jobs are inherently more risky or unpleasant than other jobs, different workers will be paid different wages because of

	differences in human capital.
	differing access to capital.

	compensating differentials
	discrimination.

Discrimination is difficult to measure empirically because

	it is hard to measure and control for differences in marginal productivity.
	data on racial and gender differences is rarely available.

	discrimination is practiced by very few employers.
	economists find no significant wage differentials due to gender or race.

Intertemporal substitution dictates that

	people will work less in periods of high productivity.
	people will spend more in periods of high productivity.

	people will work more in periods of high productivity.
	people will spend less in periods of high productivity.

A decrease in the wage rate causes the budget line to

	become flatter.
	become steeper.

	shift upward.
	shift downward.

An increase in the marginal productivity of labor will tend to

	shift the labor supply curve rightward if the change is temporary.
	result in an increase in employment if the change is temporary.

	result in an increase in employment if the change is permanent.
	all of the above.

A downward shift in a workerâs budget line is a result of

	an increase in the wage rate.
	a decrease in the wage rate.

	an increase in nonlabor income.
	a decrease in nonlabor income

One deficiency of the labor-leisure indifference curve analysis is that because indifference curves are always tangent to the workerâs budget line, the model cannot explain why some people choose not to work.

	True
	False
