| 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. | |

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.
