In the presence of strong economies of scale, a fall in transport costs can lead to a more pronounced geographical concentration of production. This is very apparent in the growing concentration of breweries in England from 1900-1970. The number of breweries in England fell sharply between 1900...

This paper studies information acquisition under competitive pressure and proposes a model to examine the relationship between product market competition and the level of innovative ac- tivity in an industry. Our paper offers theoretical support for recent empirical results that point to an...

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...

This aim of this paper is twofold. First it examines the determinants of acquisitions and divestitures of Dutch firms in the period 1996-2004. Second, it investigates the impact of acquisitions and divestitures on the firm’s innovative output performance. An econometric model is specified and...

This paper studies information acquisition under competitive pressure and proposes a model to examine the relationship between product market competition and the level of innovative activity in an industry. Recent empirical papers point to an inverted-U shape relationship between competition and...

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...

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...
