In the Solow model, an increase in investment leads to: a. an increase in growth rates in the short run but a return to zero growth in the long run as the economy converges to a new, higher steady state. b. an increase in growth rates in both the short run and the long run, as new investment will lead to permanently higher levels of the capital stock. c. a decrease in growth rates in both the short run and the long run, as fewer resources are available for production following the increase in investment. d. no change in growth rates. a 19. Growth in nominal GDP can be caused by: a. only an increase in prices over time. b. only an increase in production over time. Test 1 Prep c. an increase in either prices or production over time. d. neither an increase in prices nor an increase in production over time. c 20.
