Evidence is provided on the relationship between changes in product characteristics and product prices by constructing constant quality price indexes for hubs, a category of equipment for Local Area Networks (LANs). Relying on a database of more than 500 hubs marketed between 1990 and 1999...

We study the role that switching costs, compatibility, and mergers and acquisitions, play in influencing the evolution of a multi-market industry. By looking at the case of the Local Area Networking industry, we propose a 'history friendly model' to replicate its evolution during the 1990s. Our...

This paper presents a History Friendly Model which addresses the issue of the bifurcation in technological styles" between US and Britain during the nineteenth century. The model aims at gaining a better understanding of the micro-dynamics that gave rise to different patterns of innovation in...

We study how technological leadership affects persistence in product innovation. Relying upon a database of 1818 products marketed between 1990 and 1999 by 265 firms active in three markets of the Local Area Network (LAN) industry we first construct a measure of technological leadership and then...

We use patent citation networks to study the dynamics of technical change in Ethernet, a standard for data communication. We first consider the evolution of the broad technological system of local area networks (LANs) and we identify the most significant inventions within the specific subfield...
