Question

Quizplus · Accepted Answer

A decrease in the number of popcorn producers will decrease the supply of popcorn, as there will be fewer producers able to produce popcorn for market. A technological advance in the production of popcorn would increase the supply of popcorn, as it would make production more efficient and increase the output of popcorn. An increase in the price of popcorn would increase the supply of popcorn, as it would provide an incentive for producers to produce and sell more popcorn. A decrease in the price of popcorn would not directly impact the supply of popcorn, and may even increase demand and thus increase the supply required to meet that demand.
