Domestic producers represent a small portion of the world market and have no influence on the product price. The firm's elasticity of demand for labor is ?0.5. Suppose the wage increases by 6 percent. What will happen to the number of workers hired by the firm? What will happen to the marginal productivity of the last worker hired by the firm? Explain.
