Interest rate marginal productivity of capital
In this passage he appears to accept the view set forth above, that the rate of interest determines the point to which new investment will be pushed, given the schedule of the marginal efficiency of capital. If the rate of interest is 3 per cent., this means that no one will pay £100 for a machine unless he hopes thereby to add £3 to his The marginal cost of debt is a component in the marginal cost of capital. It is the interest rate that investors expect, adjusted for taxes. For instance, a business raises a new debt at an interest rate of 7% and the tax rate is 15%. In this case, the marginal cost of debt would be 0.07*(1-0.15) 5.95%. Investment Demand Function. According to J.M. Keynes, investment depends on the market rate of interest and the marginal efficiency of capital. A schedule that shows the relation between interest rates and marginal efficiency of capital is termed as investment demand schedule. conditions approximating perfect competition on the capital market the MPK equals the rate of return to capital, and that the latter multiplied by the capital stock equals capital income. Hence, the aggregate marginal product of capital can be easily recov-ered from data on total income, the value of the capital stock, and the capital share in
In equilibrium, the interest rate (the return on saving) is equal to the net marginal product of capital after depreciation. If the interest rate is less than the growth rate, the economy
This curve after a point is a downward sloping curve. While deciding about an investment, the entrepreneur, however, compares the marginal productivity of capital with the prevailing market rate of Interest. Marginal Productivity of Capital = the marginal physical product of capital x the price of the product.

The national income and product rises, and the rate of growth of national income and interest rate is the marginal product of capital; and the real wage is the
Investment, Tobin’s q, and Interest Rates Chong Wangy Neng Wangz Jinqiang Yangx January 8, 2013 Abstract The interest rate is a key determinant of rm investment. We integrate a widely-used term structure model of interest rates, CIR (Cox, Ingersoll, and Ross (1985)), with the qtheory of investment (Hayashi (1982) and Abel and Eberly (1994)). We With the existence of credit money, Wicksell argued, two interest rates prevail: the "natural" rate and the "money" rate. The natural rate is the return on capital – or the real profit rate. It can be roughly considered to be equivalent to the marginal product of new capital.
The national income and product rises, and the rate of growth of national income and interest rate is the marginal product of capital; and the real wage is the
If the supply price of a capital asset is Rs. 20,000 and its annual yield is Rs. 2000, then the marginal efficiency of this asset is 2000/20000 x 100 = 10 percent. Thus the marginal efficiency of capital is the percentage of profit expected from a given investment on a capital asset. Given Equation 5, the marginal product of capital is equal to the interest rate (Equation 7) if and only if Equation 9 holds [5]: (9) Proof: Equation 10 gives the total differential of both sides of Equation 5: (10)Thus, the interest rate is equal to the marginal product of capital (Equation 7) if and only if Equation 11 holds: (11)Equation 9 follows. The capitalist compares the marginal efficiency of capital and the rate of interest. Investments are made only when the rate of interest on capital is lower than the expected rate of profit from invested capital. As the gap between these two indicators increases, the capitalist’s incentive to invest becomes stronger.
Keywords: capital flows, marginal product of capital, panel data capital flows and Z is a financial indicator and is either the real interest rate or one of the four.
interest rate and the return to capital are equal. Rt+1 =αyt+1λ The marginal product of capital depends on how much capital one uses, but it also depends on how much labor is employed. If interest rates fall, the marginal labor) is a constant times the average product of capital (resp. labor). These marginal rates depend on the units used for measuring the quantities. The ratio of the
The marginal product of capital (MP K) is the additional output resulting, ceteris paribus ("all things being equal"), from the use of an additional unit of physical capital. It equals the reciprocal of the incremental capital-output ratio. Mathematically, it is the partial derivative of the production function with respect to capital. corollary, the interest rate has then been ascribed to the marginal product of capi-tal. Now, for many practical purposes, including those which Lerner had in mind, there is probably no great harm in this procedure, since the rate of interest is closely related to the marginal product of capital. Nevertheless, the procedure is In mainstream economics, it is commonplace for people to say that in a competitive equilibrium, the interest rate equals the “marginal product of capital.” This is considered to be analogous to the claim that in a competitive equilibrium, the wage rate equals the marginal product of labor.
