3.Colleges in Washington state offer many programs in information technology and computer science. Productivity of workers increases dramatically
(a)Draw a graph to show how the increase in labor productivity will affect the loanable funds market.
b)Would GDP increase or decrease?
4.Can real interest rate be higher than nominal interest rate? Explain.
3) a) Increase in labor productivity will increase demand for labor. Firms are likely to use more labor and less capital. This implies that the demand for capital will decrease and the investment should decrease. Hence the demand for funds decreases in the loanable funds market. This reduces the rate of interest
b) Effect on GDP is ambiguous. Decrease in investment would shift AD left but higher production should shift AS right. GDP can increase because higher productivity will raise income of workers and this might raise consumption
4) Real interest rate = nominal interest rate - expected inflation. If expected inflation is greater than nominal interest rate then real interest can be higher than nominal interest rate
