This paper reviews recent studies on the links between competition, innovation and productivity growth in the long run. From a long-run perspective, one can see that gains from competition-enhancing regulatory reform are likely to exceed static gains observed in the short run since firms will...

We study the effect of market structure on a personal computer manufacturer's decision to adopt new technology. This industry is unusual because there exist two horizontally segmented retail markets with different degrees of competition: the IBM-compatible (or PC) platform and the Apple...

This paper evaluates how different lengths of entry regulation impact market structure and market performance using a dynamic structural model. We formulate an oligopoly model in the tradition of Ericson and Pakes (1995) and allow entry costs to vary over time. Firms have the opportunity to...

The mixed-demand model allows for very flexible specification of what should be considered endogenous and exogenous in demand system estimation. This paper introduces a revealed preference framework to analyze the mixed-demand model. The proposed methods can be used to test whether observed data...

Firms use both innovation and advertising to increase their profits, markups, and market shares. While they serve the same purpose from the firms' perspective, their broader implications vary substantially. In this paper, we study the interaction between these two intangible inputs and analyze...

This paper analyses the impact of common ownership on markups and innovation and adds to the discussion of the recently observed patterns of a long term rise in market power. We shed light on the inconclusiveness of results regarding the effects of common ownership on markups in the existing...

In this paper, we review the literature on declining business dynamism and its implications in the United States and propose a unifying theory to analyze the symptoms and the potential causes of this decline. We first highlight 10 pronounced stylized facts related to declining business dynamism...

I analyze the innovation incentives under monopoly and duopoly provision of horizontally differentiated products purchased via bilateral negotiations, integrating the market structure and innovation literature with the holdup literature. I show that competition can improve local incentives for...

The central prediction of the Aghion et al. (2005) model is an inverted U-shaped relation between innovation and competition. The model is built on the assumption of a product market and has not yet been empirically tested on service-sector firms. Using detailed firm-level data, we find the...
