We examine the role of latecomers’ optimal resource allocation between innovation and imitation in latecomers’ catch-up under diverse technological regimes. Building on Nelson and Winter (1982), we develop computational models of technological leadership change. The results suggest that...

The issue of whether a new incompatible technology can challenge an established technology has been controversial in the literature on network effects. Some argue that such incompatible entry is difficult when the established technology has built up its installed base. Others argue that history...

The emergence of a giant cluster, in which bits and pieces of otherwise unconnected parts of a system come together, has been extensively studied in nonsocial contexts. This phenomenon has attracted substantial attention because it allows researchers to understand and predict the collective...
