This paper analyzes selection biases in the project choice of complementary technologies that are used in combination to produce a final product. In the presence of complementary technologies, patents allow innovating firms to hold up rivals who succeed in developing other system components....

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...

The recent fall in oil prices has led to extensive capital rationing, and thereby given rise to a renewed focus on parameters for project selection which supplement net present value. While the financial crisis was creating capital constraints, the oil industry seemed to be paying great...

Carbon Capture and Storage (CCS) is regarded as one of the most important technologies to mitigate climate change while providing fossil-fuel based energy security. During the past decade, projects in support of the development and deployment of the technology have been initiated across the...

We show that essentially every communication equilibrium of any finite Bayesian game with two players can be implemented as a strategic form correlated equilibrium of an extended game, in which before choosing actions as in the Bayesian game, the players engage in a possibly infinitely long (but...

We analyze the short and long run effects of demographic ageing - increased longevity and reduced fertility - on per-capita growth. The OLG model captures direct effects, working through adjustments in the savings rate, labor supply, and capital deepening, and indirect effects, working through...

This paper introduces the concept of emotions into the standard litigation contest. Positive (negative) emotions emerge when litigants win (lose) at trial and are dependent in particular on the level of defendant fault. Our findings establish that standard results of litigation contests change...

In a partial equilibrium setting without price uncertainty, the balanced-budget substitution of an ad valorem tax on output for a specific (unit) tax can enhance welfare in imperfectly competitive markets and is without impact in a competitive world. This paper demonstrates that a substitution...

Tax competition between two governments who choose nonlinear income tax schedules to maximize the average utility of its residents when skills are unobservable and labor is perfectly mobile is examined. We show that there are no Nash equilibria in which there is a skill type that pays positive...

We examine how allowing individuals to emigrate to pay lower taxes abroad changes the optimal non-linear income tax scheme in a Mirrleesian economy. An individual emigrates if his domestic utility is less than his utility abroad net of migration costs, utilities and costs both depending on...
