Climate-economy models aiming at quantifying the costs and effects of climate change impacts and policies have become important tools for climate policy decision-making. Although there are several important dimensions along which models differ, this paper focuses on a key component of climate...

The purpose of environmental taxes is to correct the market when it fails to take environmental damages into account, i.e. to internalize the Pigouvian element. In addition, fiscal taxes are levied on both polluting and clean goods, which may follow the Ramsey principle. In practical policy,...

The distributive incidence of environmental policies has not been widely investigated whereas more attention has been focused on the efficiency of environmental reforms. According to the Kyoto Protocol, domestic policies aimed at reducing carbon emissions can include carbon/energy taxes,...

Political parties compete over income tax functions, and voters vote and decide whether to pay full taxes or to make an e®ort to modify their tax bur- den. We show that political parties only propose e±cient income tax func- tions, in a similar manner to the probabilistic voting theory....

This working paper maps out the structure and value chains of the wind industry, analyzes the wind industry's increasing global integration via cross-border trade and investment flows, and offers recommendations to policymakers for the design of investment and trade policies to help realize wind...

This paper characterizes optimal income taxation when individuals respond along both the intensive and extensive margins. Individuals are heterogeneous across two dimensions: specifically, their skill and disutility of participation. Preferences over consumption and work effort can differ with...

We propose a canonical model of optimal nonlinear redistributive taxation with matching unemployment. In our model, agents are endowed with different skill levels and labor markets are perfectly segmented by skill. The government only observes negotiated wages. More progressive taxation leads to...

 We analyze the effects of trade liberalization on environmental policies in a strategic setting when there is transboundary pollution. Trade liberalization can result in a race to the bottom in environmental taxes, which makes both countries worse off. This is not due to the terms of trade...

This paper analyzes the economic and investment implications of a series of climate mitigation scenarios, characterized by different levels of ambition in terms of long term stabilization goals and the transition to attain them. In particular, the implications of fairly ambitious scenarios are...

This paper studies the implications for climate policy of the interactions between environmental and knowledge externalities. Using a numerical analysis performed with the hybrid integrated assessment model WITCH, extended to include mutual spillovers between the energy and the non-energy...
