Suppose that a firm has a budget of $12,000, that the wag rate is $10 per hour, and that the rental rate of capital is $10 per hour. If the wage rate increases to $15 per hour and the rental rate of capital rises to $120 per hour, what happens to the producer budget or isocost line? What will happen to I equilibrium level of output because of this change in facto prices? What will happen to the relative usage of labor and capital because of the change in factor prices? Explain.
