Airplanes were invented by hobbyists and experimenters, and some personal computers were as well. Similarly, many open-source software developers are interested in the software they make, and not focused on profit. Based on these cases, this paper has a model of agents called tinkerers who want...

We attempt to extend the static analysis of innovator networks by providing case study based insights into the dynamic, developmental or evolutionary pattern of such networks. In the theoretical part, we develop some building blocs that are considered central to a theory of network evolution....

Modern software development involves collaborative efforts and re-use of existing software packages and libraries, to reduce the cost of developing new software. However, package dependencies expose developers to the risk of contagion from bugs or other vulnerabilities. We study the formation of...

In the last fifteen years, income differences among European Member States have been strongly narrowing while the process has been matched with a widening of the inter-regional variance within single countries. Traditionally, regional economic disparities in Europe have been ascribed to...

Based on a novel dataset constructed with the supplier-consumer paired sample, this paper uses a difference-in-differences approach to evaluate the impact of national high-tech zones on firm performance. We find that the supplier's sales growth rate increased by about 61.35% after the approval...

We investigate how political ideology affects corporate innovation by using the expansion of Sinclair Broadcasting, the largest conservative media network in the U.S., as a plausible shock to the local ideology. We find that innovation quantity (patent counts) and quality (citation counts per...

This paper discusses the technological upgrading of China in photovoltaics technology. It explores the patterns of innovation and network embeddedness and their impact on economic performance at the firm level. Identifying the main innovators over 1995-2014 with patent and market share...
