Question

According to the Solow model, an increase in the capital-labor ratio will a. always increase steady state consumption per worker b. reduce steady state consumption per worker if the capital-labor ratio is below the Golden rule capital stock c. always reduce steady state consumption per worker d. increase steady state consumption per worker if the capital-labor ratio is below the Golden rule capital stock

2. In a steady state a. capital and labor, by definition, are inversely related to one another b. both consumption per worker and the capital-labor ratio are constant c. consumption per worker can change, but the capital-labor ratio is constant d. consumption per worker is constant, but the capital-labor ratio can change

4. In the long run, a reduction in productivity will cause a. an increase in the capital-labor ratio and a decrease in consumption per worker b. a decrease in the capital-labor ratio and a decrease in consumption per worker c. a decrease in the capital-labor ratio and an increase in consumption per worker d. an increase in the capital-labor ratio and an increase in consumption per worker

5. An increase in the growth rate of population in a steady-state economy would cause a. a pivot down and to the right in the investment line b. a parallel shift downward in the investment line c. a pivot up and to the left in the investment line d. a parallel shift upward in the investment line 1 2

6. In the efficiency wage model, an increase in productivity would a. have no effect on either output or the real wage b. increase output but have no effect on the real wage c. decrease the real wage but have no effect on output d. increase output but decrease the real wage
