My aim is to develop a comparative political economy of sustainable development. In doing so, I aim to understand the constraints and opportunities of various institutional arrangements for responding to ecological and social challenges. Elements of this research agenda include 1) what forms of state-business relations can facilitate directed technical change? 2) how can we institutionalize the consideration of the long-term? 3) what is the political role of different forms of citizen participation? 4) can some institutions facilitate collective learning? 5) how do different types of property rights affect the robustness of social-ecological systems?
