Explore how production translates capital and labor into output in the short run and long run. Examine costs, and the average and marginal product of labor in a competitive market.

The value of marginal product of labor equals the price of output times the marginal product of labor. Wages rise with higher output prices or efficiency when marginal product increases.

Analyze the marginal value product of labor and its influence on wages, then define explicit, implicit, sunk, fixed, and variable costs, and outline short-run cost curves with diminishing returns.

Explore market structures from perfect competition to monopoly, including monopolistic competition and oligopoly, and analyze how supply, demand, price, and marginal revenue shape outcomes.
