Endogenous Market Structures and Innovation by Leaders: an Empirical Test
Simple models of competition for the market with endogenous entry show that, contrary to the Arrow view, an endogenous entry threat in a market induces the average firm to invest less in R&D and the incumbent leader to invest more. We test these predictions based on a unique dataset and survey for the German manufacturing sector (the Mannheim Innovation Panel). In line with our predictions, endogenous entry threats as perceived by the firms reduce R&D intensity for the average firm, but they increase it for an incumbent leader. These results hold after a number of robustness tests with instrumental variable regressions.
