Water management provides a critical lens onto the development process. For the last several centuries, improvements in clean water and sanitation have contributed to better health and increased life expectancies. Currently, however, developing countries seem unable to make much progress in...

Where nations depend on resources originating outside their borders, such as river water, some believe that the resulting international tensions may lead to conflict. Homer-Dixon (1999) and Toset et al. (2000) argue such conflict is most likely between riparian neighbours, with a militarily...

In this report, we outline a method for approximating a Markovian (or feedback-Nash) equilibrium of a dynamic game, possibly subject to coupled-constraints. We treat such a game as a "multiple" optimal control problem. A method for approximating a solution to a given optimal control problem via...

Governments sometimes promote rules backed by sanctions too weak to make obedience privately optimal. Factors that may help make such rules effective include the presence of informal sanctions by peers, and implementation through voting. I study the impact of non-deterrent formal sanctions on...

I show how improper conditioning of beliefs can lead to under-contribution in public goods environments with interdependent values. I consider a simple model of a binary, excludable public good. In equilibrium, provision of the public good is good news about its value. Naive players who...

Studies show that identifying contributors increases contributions to public goods. In practice, viewing identifiable information is costly, which may discourage people from accessing it. We design a public goods experiment in which participants can pay to view information about identities and...

We experimentally investigate the impact of visibility of contributors and cost of information on public good contributions. First, we vary recognizing all, highest or lowest contributors. Second, we investigate the effect of imposing a cost on viewing contributors. Recognizing all contributors...

We analyze a team formation process that generalizes matching models and network formation models, allowing for overlapping teams of heterogeneous size. We apply different notions of stability: myopic team-wise stability, which extends to our setup the concept of pair-wise stability, coalitional...
