Working Paper No. 66. Eliasson, Gunnar & Johansson, Dan (2005). Firm Tunrover and the Rate of Macroeconomic Growth – Simulating the Macroeconomic Effects of Schumpeterian Creative Destruction.
Abstract: The positive effects of new innovative entry and fast and efficient allocation of resources are balanced against the efficiency of price signaling in markets in a non-linear micro based simulation model of an Experimentally Organized Economy (EOE). In this model increasingly rapid reallocation of resources over markets, moved by innovative new entry and competitive exit (the rate of firm turnover) generates faster growth in output, but eventually, if too fast, is shown to affect the reliability of price signaling in markets and to raise the frequency of investment mistakes. Beyond a certain level of the rate of firm turnover the aggregate effects at the macro level, therefore, turn negative. This optimal growth trajectory depends on the balance between the rates of entry and exit and on the performance of new firms compared to incumbents, their size compared to incumbents and the variation in the same characteristics.
