Classical competition and regulating capital: theory and empirical evidence

Abstract In this article we discuss the salient features of the classical and neoclassical theories of competition and we test their fundamental propositions using data from Greek manufacturing industries. The cross section data of 3-digit (total 91) industries of the three (pooled together) census years show no evidence of a direct statistical relationship between the degree of concentration and profitability. The econometric analysis of time series data for 2-digit industries lends support to the hypothesis for the long-run tendential equalization of incremental rates of profit to the economy’s average.
