Which of the following scenarios would likely shift the supply curve for potatoes to the right (increase in supply)?

a. Potato growers expect the price of potatoes to be lower this year than last year.
b. A new harvester enables farmers to bring in ripe potatoes twice as fast as they did before.
c. The price of fertilizer increases.
d. Teenagers in potato-farming towns leave to go to college

The correct answer is option b.

Explanation:

The supply curve for potatoes can shift to the right because of an increase in the supply. The supply for a product may arise because of several reasons such as improvement in technology or reduction in the cost of production.

In the given options, the use of new harvester that allows the farmer to bring in ripe potatoes at twice the speed than earlier will help the farmer to increase supply. This will further cause the supply curve to move to the right.
