The World's nations have yet to reach a truly effective treaty to control the emission of greenhouse gases.  The importance of compatibility with private incentives of individual countries has been acknowledged (at least by game theorists) in designing climate policies for the post-Kyoto...

Game harmony is a generic game property that describes how harmonious (non-conflictual) or disharmonious (conflictual) the interests of players are, as embodied in the payoffs. It can be used to predict cooperation in two-player games. We show how, for large enough positive harmony...

It is common to model costs of carrying out strategies in games in relation to the complexity, in some sense, of the strategies. We show a particularly general definition of complexity for this purpose, one that subsumes many alternatives as special cases. We explore how this definition can be...

A person is said to be `trust responsive` if she fulfils trust because she believes the truster trusts her. The experiment we report was designed to test for trust responsiveness and its robustness across payoff structures, and to disentangle it from other possible factors making for...

Africa is well endowed with potential for hydro and solar power, but its other endowments - shortages of capital, skills, and governance capacity - make most of the green options relatively expensive, while its abundance of hydro-carbons makes fossil fuels relatively cheap.  Current power...

While it is clear that natural disasters have serious welfare consequences for affected populations, less is known with respect to how local labour markets in low income countries adjust to such large shocks in particular the general equilibrium effects of the increase in the demand for...

Climate policy requires that much of the world's reserves of fossil fuels remain unburned.  This paper makes the case for implementing this directly through policy to close the global coal industry.  Coal is singled out because of its high emissions intensity, low rents per unit value, local...

Climate physics predicts that the intensity of natural disasters will increase in the future due to climate change.  One of the biggest challenges for economic modeling is the inherent uncertainty of climate events, which crucially affects consumption, investment, and abatement decisions.  We...

We study the effects of greenhouse gas emissions on optimum growth and climate policy by using an endogenous growth model with polluting non-renewable resources.  Climate change harms the capital stock.  Our main contribution is to introduce and extensively explore the naturally determined...

There is widespread concern that an international agreement on stringent climate policies will not be reached because it would imply too high costs for fast growing economies like China.  To quantify these costs we develop a general equilibrium model with fully endogenous growth.  The...
