Answer to Question 1

Economists have three main uses for the model. First, its assumptions are reasonably close to actual conditions in some markets. Second, if a market satisfies some but not all of the assumptions, we often start from perfect competition and then see what happens when we replace the usual assumptions with more realistic ones. Third, the perfectly competitive market is a standard for analyzing consumer and producer benefits.
