Theoretical and empirical shortcomings of the Kaleckian investment function

The specification of the accumulation function is critical for the properties and implications of structuralist and post-Keynesian models. A large Kaleckian literat- ure assumes that investment is relatively insensitive to variations in the utilization rate of capital, and this extension of a standard short-run "Keynesian stability con- dition" to the long run has been defended by Lavoie and Dutt, among others. This paper examines the theoretical and empirical arguments for and against a Kaleckian specification. JEL Categories: E12, E32
