A backward-bending labor supply curve could possibly imply which of the following cases?

A) Leisure is an inferior good.
B) Leisure is a normal good.
C) Leisure is a normal good at low wages and inferior at high wages.
D) None of the above.

Question 2

To dig a trench, each worker needs a shovel. Workers can only use one shovel at a time. Workers without shovels do nothing, and shovels cannot operate on their own.

What kind of production technology is this? Graphically (with isocost and isoquant lines) determine the optimal number of shovels and workers used by a firm to dig two trenches when w = r = 10. What will be the (long-run) total cost of the two trenches? What will happen if the rental rate drops to 5 while the wage remains at 10? Add the relevant lines to your graph and compute the new optimal quantity of inputs and total cost.

Answer to Question 1

B

Answer to Question 2

This is the fixed-proportion production technology. In order to dig two trenches, it must be that L = 2 and K = 2, so the total cost will be 40. If the rental rate drops, the optimal K and L remain unchanged and the cost falls to 30.
