BINARY CHOICE QUESTIONS -

1. Consider the market for Idaho potatoes. The supply is very inelastic in the short run since farmers in Idaho cannot increase or decrease the supply of potatoes in the fall since the supply depends on how many seed potatoes they put in the ground in March.

Given this information, if the government levies an excise tax on Idaho potato farmers, who will bear more of the economic tax burden?

a. Potato farmers in Idaho

b. Consumers of Idaho potatoes
