This paper provides an empirical analysis of the effects of new product versus process innovations on export propensity at the firm level. Product innovation is a key factor for successful market entry in models of creative destruction and Schumpeterian growth. Process innovation helps securing...

This paper investigates how different damage rules in patent infringement cases shape competition when intellectual property rights are probabilistic. I develop a simple model of oligopolistic competition to compare two main liability doctrines that have been used in the US to assess...

This paper considers a dynamic model of the evolution of open source software projects, focusing on the evolution of quality, contributing programmers, and users who contribute customer support to other users. Programmers who have used open source software are motivated by reciprocal altruism to...

A long period of rig scarcity and high rates has led to innovation in the procurement of rig services and in relationships between oil companies and rig contractors. Discussions have been conducted on joint ventures between companies and contractors, for instance. This paper describes and...

It has been argued that monetary incentives restrain individual creativity and hamper performance in jobs requiring out of the box thinking. This paper reports from an experiment designed to test if the negative incentive effect is present also when individuals work together to solve such...

In a standard adverse selection world, asymmetric information about product quality leads to quality deterioration in the market. Suppose that a higher investment level makes the realization of high quality more likely. Then, if consumers observe the investment (but not the realization of...

School systems regularly use student assessments for accountability purposes. But, as highlighted by our conceptual model, different configurations of assessment usage generate performance-conducive incentives of different strengths for different stakeholders in different school environments. We...

There is an emerging consensus that carbon emissions must be limited. An attractive approach to promoting carbon reductions is to encourage reductions in deforestation. But any such strategy must confront a basic problem: agents that might be induced to reduce their actions which would reduce...

I study an indefinitely repeated game where firms differ in size. Attempts to form cartels in such an environment, for example by rationing outputs in a manner linked to firm size differences, have generally struggled. Any successful cartel has to set production shares in a manner that ensures...

We construct a Hotelling-type model of two media providers, each of whom can issue fake and/or real news and each of whom can invest in the debunking of their rival's fake news. The model assumes that consumers have an innate preference for one provider or the other and value real news. However,...
