Document Summary

Suppose the labor supply curve is upward sloping and the labor demand curve is downward sloping. The study of economic trends over a particular time period reveals that the wage recently fell while employment levels rose. If the supply curve does not shift, all wage and employment movements must occur along the supply curve, so that the wage rate and the employment level must move in the same direction. Because the wage went down while employment went up in the situation described in the question, it must have been the case that the supply curve shifted outwards (to the right). We do not have enough information to determine whether the demand curve shifted as well. It takes time to produce a new economist, and prospective economists base their career decision by looking only at current wages across various professions. Further, the labor supply curve of economists is much more elastic than the labor demand curve.

In the indifference curve budget line model of labor supply,

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.

labor’s marginal product.

the worker’s 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.

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 worker’s 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.

Discrimination is difficult to measure empirically because

it is hard to measure and control for differences in marginal productivity.

A downward shift in a worker’s 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 worker’s budget line, the model cannot explain why some people choose not to work.
