In the augmented Solow model, what is the effect of a permanent increase in the productivity level A on the long-run rental rate of capital (R*)? Assume that Y = AFUQ, ZtNt) = AKf(ZtNt)1_G. A. Higher A increases the marginal product of capital, which increases the demand for capital and then increases 53*. B. Higher A increases the marginal product of capital, which increases the demand for capital and then R". However, it also increases investment, which then increases the supply of capital in the long-run. The total effect is a decrease in R*. C. Higher A increases the marginal product of capital, which increases the demand for capital and then 5"\". However, it also increases investment, which then increases the supply of capital in the long-run. The total effect is an increase in If\". D. Higher A increases the marginal product of capital, which increases the demand for capital and then R". However, it also increases investment, which then increases the supply of capital in the longrun. Both effects cancel out and R\" is unchanged. In the augmented Solow model, which of the following shocks generate no jump (contemporaneous change) in the evolution of any per-efficiency unit variable k, y, c, i ? A. A higher saving rate (s). B. An increase in population growth (n). C. A change in the importance of capital in production (a). D. An increase in productivity ( A)
