When he does this, the marginal cost of the last shirt he produces is , which is than the price Sam receives for each shirt he sells. The marginal cost of producing an additional shirt (that is, one more shirt than would maximize his profit) is , which is than the price Sam receives for each shirt he sells. Therefore, Sam's profit-maximizing quantity corresponds to the intersection of the curves. Because Sam is a price taker, this last condition can also be written as .arrow_forward

As an economic advisor to the governor, you have been asked to provide a recommendation on whether the minimum wage should be increased based on economic theory. Consider the labor market data provided. Prepare a brief report that: 1. Explains whether the labor market is currently efficient at the equilibrium wage of $15 per hour. How would you know? At equilibrium, what (dollar amount) is the Total Surplus this market provides? Show your rationale with numbers. 2.
