Incomplete information on the degree to which governments internalize the long-run interests of the state is an essential element of information asymmetry in international relations. A reputational model with such incomplete information captures two observed facts: i. costly activities, among...

A standard Ak-model of endogenous growth has been extended to allow for an intertemporal conflict between capitalists and workers. For the dynamic game thus obtained, an equilibrium solution in feedback Nash (Markovian) strategies have been computed. However, many equilibria in trigger...

Global warming is an example of a global tragedy of the commons. The atmosphere is a global common property resource. The global nature of this resource makes global warming a particularly difficult problem to solve. The reason for this is that there is no world government that can introduce and...

This paper develops a theoretical foundation for the social cost of carbon (SCC). The model highlights the source of debate over whether countries should use the global or domestic SCC for regulatory impact analysis. I identify conditions under which a country's decision to internalize the...

We show that a technological breakthrough that reduces CO2 emissions per output can exacerbate the climate change problem: countries may respond by raising their emissions resulting in an increase of the stock of pollution that may reduce welfare. Using parameter values based on empirical...

We model countries' choice of greenhouse gas (GHG) emissions as a dynamic game. Emissions generate immediate benefits to the emitting country but also increase atmospheric GHG concentrations that negatively affect present and future welfare of all countries. Because there are no international...

This paper presents a theory of optimal multilateral trade agreements with public political shocks. Optimal multilateral agreements exhibit "forbearance'' – where one country withholds retaliation when its trading partner receives a shock. This provides a rationale for countries not acting on...
