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...

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...

We study how net neutrality regulations affect a high-bandwidth content provider's (CP) investment incentives in quality of services (QoS). We find that the effects crucially depend on network capacity levels. With limited capacity, as in mobile networks, prioritized delivery services are...

What is the best way to reward innovation? While prizes avoid deadweight loss, intellectual property selects high social surplus projects. Optimal innovation policy thus trades off the ex-ante screening benefit and the ex-post distortion. It solves a multidimensional screening problem in the...

Colombian manufacturing exporting firms survey results are analyzed highlighting innovation, promotion, and learning, as well as the influence of factors such as: size, ownership, output objectives, destination of exports, competition and pricing, export incentives, and firm configuration, in...

In this paper, we study entrepreneurial innovations in an industry characterized by network effects. We show that the presence of network externalities tends to make the entrepreneur prefer sale to entry. Moreover, we also show that the incentive to innovate for entry decreases when network...

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...

“Software platforms are the invisible engines that have created, touched, or transformed nearly every major industry for the past quarter century. They power everything from mobile phones and automobile navigation systems to search engines and web portals. They have been the source of enormous...
