We study the role of inter-group differences in the emergence of conflict. In our setting, two groups compete for the right to allocate society’s resources, and we allow for costly inter-group mobility. The winning group offers an allocation, that the opposition can either accept, or reject...

Over the period of 1995-2005 an increasing number of differentiated products have been exported from developing countries. For example, while Chinese products had exported to 40.5% more markets on average, the corresponding numbers for Japan and the United States were almost constant. Using the...

This paper tests the robustness of the "two-tiered market" in which efficient bilateral contracts emerge between firms and workers (Brown, Falk and Fehr, 2004). Our experiment introduces stochastic interruptions in firms' ability to offer contracts. Involuntarily laid off workers are eager to be...

This paper describes a randomized field experiment testing the impact of a savings competition on the behavior of homeless individuals staying at a transitional shelter. When monetary prizes were offered for achieving the highest savings rates within a particular month, savings increased while...

This paper introduces a model of endogenous growth through basic and applied research. Basic research differs from applied research in the nature and the magnitude of the generated spillovers. We propose a novel way of empirically identifying these spillovers and embed them in a general...

We develop a microeconomic model of endogenous growth where clean and dirty technologies compete in production and innovation-in the sense that research can be directed to either clean or dirty technologies. If dirty technologies are more advanced to start with, the potential transition to clean...

There is substantial heterogeneity across industries in the level of interdependence between new and old technologies. I propose a measure of this interdependence—an index of sequentiality in innovation—which is the transfer rate of patents in a particular industry. I find that...
