We analyze the use of patent protection as a new policy to direct technical change to clean technology. Contrary to popular belief, it is dirty (and not clean) innovations that should be excluded from patent protection to reduce emissions. In the shortrun, removing patent protection on dirty...

There is widespread concern that climate policy is moving too slowly and that decarbonization of economic development is coming too late for effective climate protection. We analyze three different effects that emerge endogenously during decarbonization and amplify current policies: growing...

Subglobal climate policies induce changes in international competitiveness and favor a relocation of carbon-emitting activities to non-abating regions. In this paper, we evaluate the potential for CO2 abatement and the emissions `leakage' effect in the copper industry, a prominent...

How should governments best allocate their budget to support private research activities? The consensus in the literature is that sector-specific R&D support policies should be increasing in the degree of compatibility of sectoral innovation with the practices of the wider economy. Using a...

Countries such as Germany and Switzerland have included the energy transition in their policy programs, setting specific targets in terms of energy production from renewables. However, the energy transition has a cost, which so far has been partly covered by subsidizing the clean production....

There are concerns that climate-related physical and political risks are not yet properly reflected in asset prices. To address these concerns, we develop a dynamic asset pricing framework with two sources of rare disasters: macroeconomic events and climate change. We link carbon emissions and...

We study clean energy subsidies in a quantitative climate-economy model. Clean energy subsidies decrease carbon emissions if and only if they lower the marginal product of dirty energy. The constrained-efficient subsidy equals the marginal external cost of dirty energy multiplied by the marginal...

Soils are often subject to environmental shocks which are caused by negative extern- alities linked to overexploitation. We present a stochastic model of a dynamic agricultural economy where natural disasters are sizeable, multiple, and random. Expansion of agricultural activities raises...

We determine optimal climate policy using a dynamic climate model that accounts for the damages to capital and human health from burning fossil fuels. Our theoretical macroeconomic approach incorporates a separate health sector into an integrated climate-economy framework and provides...

We study theoretically and numerically the effects of an environmental tax reform using endogenous growth theory. In the theoretical part, mobile labor between manufacturing and R&D activities, and elasticity of substitution between labor and energy in manufacturing lower than unity allow for a...
