Firm entry and turnover: the nexus with profitability and growth

The paper presents a new sectoral taxonomy, which classifies industries according to the opportunity and cost of experimentation. Econometric tests show for a sample of 24 countries that in the 1990s 'entrepreneurial' industries with a mutable and growing firm population experienced the highest growth in terms of value added and employment, but also the lowest growth of labour productivity. 'Entrepreneurial' industries generally earned a better profit-ratio than 'routinised' industries with an inertial population. The results are consistent with entrepreneurial theories of market competition, which suggest that entry follows profit opportunities but does not deplete them.
