An extensive empirical literature indicates that, even without formal intellectual property rights, innovators enjoy a variety of first-mover advantages and that `imitation' is itself a costly activity. There is also accumulating evidence that an `open' approach to knowledge production can...

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...

This paper examines the implications of Open Source License (OSL) selection on software innovation, and suggests how modifying the Open Source Definition, or modifying certain provisions in OSLs that have become de-facto standard licenses in open source development, could better accommodate the...

The traditional view of innovation, which implies that companies innovate on their own, has been recently challenged by the 'open' innovation concept promoting the use of external knowledge. Collaboration between firms has always existed in one way or another, however, large-scale open...

This paper aims to make contributions to comparative analysis of regional economic dynamics in China and the US from the methodological perspective. More specifically, some recent advances in exploratory space-time data analysis (ESTDA) will be suggested and implemented to conduct this task in...

We study an endogenous growth model where a profit-motivated R and D sector coexists with the introduction of free blueprints invented by philanthropists. These goods are priced at marginal cost, contrary to proprietary ones which are produced by a monopoly owned by the inventor. We show that...

Much of today's software relies on programming code shared openly online. Yet, it is unclear why volunteer developers contribute to open-source software (OSS), a public good. We study OSS contributions of some 22,900 developers worldwide on the largest online code repository platform, GitHub,...
