This paper analyses the dynamic aspects of knowledge sharing in R&D rivalry. In a model where research projects consist of N sequential stages, our goal is to explore how the innovators' incentives to share intermediate research outcomes change with progress and with their relative positions in...

This paper builds a theoretical foundation for the dynamics of knowledge sharing in private industry. In practice, research and development projects can take years or even decades to complete. We model an uncertain research process, where research projects consist of multiple sequential steps....

We consider a model of innovation that distinguishes between ideas and innovations. While innovation responds to incentives, ideas are a scarce resource that provide an exogenous constraint on the rate of innovation. We investigate how the optimal reward structure is shaped by the scarcity of...

We consider mergers between multi-product firms in a market with monopolistically competitive fringe of single-product firms. Aggregate product variety is determined by product variety choices of multi-product firms and entry/exit decisions of single-product firms. Mergers can generate marginal...

This paper considers the potential for the cultural transmission of attitudes toward work, welfare, and individual responsibility to explain the intergenerational correlation in welfare receipt. Specifically, we investigate whether 18-year olds' views about social benefits and the drivers of...

We develop a model of strategic contractual incompleteness that identifies conditions under which principals might omit even costlessly verifiable terms. We then use experiments to test comparative statics predictions of the model. While it is well known that verifiability imperfections can...

Cultural traits play a significant role in the determination of economic outcomes and institutions. This paper presents evidence from laboratory experiments on the cultural integration of individuals of Chinese ethnicity in Australia, focusing on social preferences, preferences for competition,...
