In Silicon Valley's computer cluster, skilled employees are reported to move rapidly between competing firms. This job-hopping facilitates the reallocation of resources towards firms with superior innovations, but it also creates human capital externalities that reduce incentives to invest in...

Observers of Silicon Valley's computer cluster report that employees move rapidly between competing firms, but evidence supporting this claim is scarce. Job-hopping is important in computer clusters because it facilitates the reallocation of talent and resources toward firms with superior...

The information technology sector in Europe, comprising the production of computer hardware and software, is disproportionately located on the continent’s western periphery. The vast bulk of computers sold in Europe in the 1990s were assembled either in Ireland or Scotland, while Ireland also...

This paper analyzes decisions on (in)compatibility and product design of two competing hardware suppliers in the presence of network effects. We show that they either establish compatibility and differentiate their variants strongly or maintain incompatibility and locate their variants at the...

In this paper we present a history-friendly model of the changing vertical scope of computer firms during the evolution of the computer and semiconductor industries. The model is history friendly, in that it attempts at replicating some basic, stylized qualitative features of the evolution of...

This paper analyzes the compatibility decision of a dominant hardware supplier. There are two substitutive variants of the hardware component of a hardware-software system, they are horizontally differentiated, and one of the two has a quality advantage. Among other things, we show under what...
