## You will increase capacity as long as (a) the expected marginal product of capital is positive. (b) the expected marginal product of capital is greater than or equal to the marginal product of capital. (c) the expected marginal product of capital is greater than or equal to the expected marginal product of labor.

### Interest rates are the rate of growth of money per unit of time. It is one of the most fundamental factors in investments, since so many financial assets depend on its value. It is used to determine the present and future value of money and of annuities.Many securities either pay interest or the payoff depends on the interest rate.

b. the nominal interest rate must be equal to expected inflation. a. higher nominal interest rates (i) in the medium run and no change in real interest rates (r ) in

### of Interest, where he argued that the nominal interest rate would be equal to the real interest rate plus the expected level of inflation. The equation: i = r + πe.

The assumption of long-run ex ante PPP implies that r = r in the long run to the extent that the real interest rate differential reflects an expected long-run The ex post real return on a nominal bond is equal to R t d t, the nominal interest rate, plus the realized rate of depreciation of the purchasing power of money, Parameters of the low-frequency variables are constrained to be equal across countries, which higher real interest rates might reflect increases in expected future profitability. where: r is the low frequency long-term real interest rate,.

of Interest, where he argued that the nominal interest rate would be equal to the real interest rate plus the expected level of inflation. The equation: i = r + πe. The Original Fisher Model. Irving Fisher's theory of interest rates relates the nominal interest rate i to the rate of inflation π and the "real" interest rate r. The than long bonds, and x is the expected rate of growth of real dividends.2. If both Sy and x were equal to zero, DIP would equal R.
