Abstract

The paper argues that the several theories used to support the traditional thesis of a dependence of investment on the interest rate are all unconvincing. The following theories are reviewed: pre-Keynesian, Keynes, array of opportunities, Lerner, Jorgenson, adjustment costs, Tobin's q. It is concluded that the difficulties, which empirical research finds in confirming a significant dependence of aggregate investment on the interest rate, are not surprising: there is simply no convincing theoretical reason why such a dependence should be observed.
