In the abscence of a global agreement to reduce greenhouse gas emissions, individual countries have introduced national climate policies. Unilateral action involves the risk of relocating emissions to regions without climate regulations, i.e., emission leakage. A major channel for leakage are...

In absence of joint global climate action, several jurisdictions unilaterally restrict their domestic demand for fossil fuels. Another policy option for fossil fuel producing countries, not much explored, is to reduce own supply of fossil fuels. We explore analytically and numerically how...

Recent literature on biofuels has questioned whether biofuels policies are likely to reduce the negative effects of climate change. In this paper we make two contributions to the literature. First, we study the market effects of a renewable fuel standard in a dynamic model taking into account...
