$$C = 30$$, $$U = \sqrt{30} \times \sqrt{5}$$

Q: Suppose a worker's utility function is $$U = C$$^{0.5}$$L^{0.5}$$, wage $$w = 2$$, and asset income $$A = 20. If $$the worker chooses $$L = 8$, what is their consumption and utility?

$$C = 36$$, $$U = \sqrt{36} \times \sqrt{8}$$

Q: Suppose a worker's utility function is $$U = C$$^{0.5}$$L^{0.5}$$, wage $$w = 2$$, and asset income $$A = 20. If $$the worker chooses $$L = 6$, what is their consumption and utility?

$$C = 32$$, $$U = \sqrt{32} \times \sqrt{6}$$

Question 1

Suppose a worker faces the budget constraint $$C = wL + A$$, where $$C is $$consumption, $$w is $$the wage rate, $$L is $$hours worked, and $$A is $$asset income. If $$w = 2$$ and $$A = 20$$, what is the maximum amount of consumption the worker can achieve if they work 10 hours?

Accepted Answer

$$C = 40$$

Question 2

Given the utility function $$U = C$$^{0.5}$$L^{0.5}$$, where $$C is $$consumption and $$L$ is leisure, which of the following best describes the marginal rate of substitution (MRS) between leisure and consumption?

Accepted Answer

$$MRS = \frac{L}{C}$$

Question 3

A worker receives a wage of $$w = 3$$ dollars per hour and has asset income $$A = 18$$ dollars per day. If the worker chooses to work $$L$$ hours, what is the equation for their budget line?

Accepted Answer

$$C = 3L + 18$$

Question 4

If a worker's wage increases, which of the following best describes the substitution effect?

Accepted Answer

The worker will supply more labor because leisure becomes more expensive.

Question 5

Suppose a worker has a utility function $$U = C$$^{0.5}$$L^{0.5}$$, a wage of $$w = 2$$, and asset income $$A = 16$. If the worker chooses not to work at all, what is their consumption?

Accepted Answer

$$C = 16$$

Question 6

A worker faces two job offers: Job A pays $$w_A = 2$$ per hour with $$A_A = 16$$ asset income, and Job B pays $$w_B = 1$$ per hour with $$A_B = 24$$ asset income. If the worker wants to maximize consumption by working 8 hours, which job should they choose?

Accepted Answer

Job B, because $$C_B = 32$$

Question 7

If the wage rate increases from $$w = 2 to$$ $$w = 3$$ and asset income remains at $$A = 20$$, what happens to the slope of the budget line in a consumption-leisure diagram?

Accepted Answer

The slope becomes steeper, indicating a higher opportunity cost of leisure.

Question 8

A worker with utility $$U = C$$^{0.5}$$L^{0.5}$$, wage $$w = 2$$, and asset income $$A = 20$$ faces a budget constraint $$C = 2L + 20. If $$the worker chooses $$L = 5$, what is their consumption and utility?

Accepted Answer

$$C = 30$$, $$U = \sqrt{30} 	imes \sqrt{5}$$

Question 9

If leisure is a normal good, what happens to the amount of leisure chosen when non-labor income increases?

Accepted Answer

Leisure increases.

Question 10

Suppose a household is a saver in capital markets and faces a budget constraint $$C_1$$ + \frac{$$C_2$$}{1+r} = $$Y_1$$ + \frac{$$Y_2$$}{1+r}$$, where C_1$ and C_2$ are consumption in periods 1 and 2, Y_1$ and Y_2$ are incomes, and r$ is the interest rate. If r$ increases, what happens to the opportunity cost of current consumption?

Accepted Answer

It increases, making future consumption relatively cheaper.

Question 11

A worker with utility $$U = C$$^{0.5}$$L^{0.5}$$, wage $$w = 2$$, and asset income $$A = 20$$ faces a budget constraint $$C = 2L + 20. If $$the worker chooses $$L = 0$, what is their consumption and utility?

Accepted Answer

$$C = 20$$, $$U = 0$$

Question 12

If a worker's reservation wage is $$w^* = 4$$ and asset income is $$A = 16$$, what is the minimum wage at which the worker will supply labor?

Accepted Answer

$$w = 4$$

Question 13

Suppose a worker's utility function is $$U = C$$^{0.5}$$L^{0.5}$ and the wage rate increases. Which effect describes the tendency to substitute labor for leisure?

Accepted Answer

Substitution effect

Question 14

A worker with $$U = C$$^{0.5}$$L^{0.5}$$, wage $$w = 2$$, and asset income $$A = 20$$ faces a budget constraint $$C = 2L + 20. If $$the worker chooses $$L = 10$, what is their consumption?

Accepted Answer

$$C = 40$$

Question 15

If the marginal rate of substitution (MRS) between leisure and consumption is high, what does this indicate about the worker's preferences?

Accepted Answer

The worker values leisure much more than consumption.

Question 16

Suppose a worker's utility function is $$U = C$$^{0.5}$$L^{0.5}$$, wage $$w = 2$$, and asset income $$A = 20. If $$the worker chooses $$L = 8$, what is their consumption and utility?

Accepted Answer

$$C = 36$$, $$U = \sqrt{36} 	imes \sqrt{8}$$

Question 17

If a worker's wage increases and leisure is an inferior good, what happens to the amount of leisure chosen?

Accepted Answer

Leisure decreases.

Question 18

A household faces a budget constraint $$C_1$$ + \frac{$$C_2$$}{1+r} = $$Y_1$$ + \frac{$$Y_2$$}{1+r}$$ in the capital market. If the interest rate r$ increases, what is the effect on the household's saving behavior?

Accepted Answer

The household is likely to save more because future consumption becomes relatively cheaper.

Question 19

Suppose a worker's utility function is $$U = C$$^{0.5}$$L^{0.5}$$, wage $$w = 2$$, and asset income $$A = 20. If $$the worker chooses $$L = 6$, what is their consumption and utility?

Accepted Answer

$$C = 32$$, $$U = \sqrt{32} 	imes \sqrt{6}$$
