Economic thought on climate policy as an instance of environmental regulation is strongly influenced by the principle of a uniform carbon price. Economists acknowledge that this principle breaks down in a second-best world with other distortions, such as taxes and market power in domestic and...

We collect data on 24,000 state aid cases within the European Union to create granular measures of national environmental support and study their interactions with the European Union Emissions Trading System (EU ETS). Exploiting variation in regulated installations' exposure to carbon prices and...

We quantitatively characterize optimal carbon, capital, and labor income taxes in an economy-climate integrated assessment model that features overlapping generations and distortionary fiscal policy. First, we show that the optimal carbon tax significantly differs from the Pigouvian carbon levy...

Economic models of climate policy (or policies to combat other environmental problems) typically neglect psychological adaptation to changing life circumstances. People may adapt or become more sensitive, to different degrees, to a deteriorated environment. The present paper addresses these...

A major concern in climate negotiations is that decarbonization may significantly hurt the development process. This paper shows that international specialization can contribute to making environmental and economic objectives compatible. When carbon efficiency differs between two trading...

This paper analyzes the efficiency consequences of local revenue policies if jurisdictions try to attenuate the pressures of inter-regional competition for mobile factors by substituting attention-grabbing tax instruments that spotlight an additional tax burden with rather inconspicuous ones. We...
