Several studies have analyzed the trade and output effects of the Transatlantic Trade and Investment Partnership (TTIP) between the United States and the European Union, but our paper is the first attempt to study its welfare effects. We measure the welfare effect of TTIP as the percentage of...

We analyze the positive and normative effects of a progressive tax on wages in a nonlinear New Keynesian DSGE model in the presence of demand and technology shocks. The non-linearity allows us to disentangle the effects of the progressive tax on the volatility and the level of macroeconomic...

We analyze the effects of a large place-based policy, subsidizing up to 50% of investment costs of manufacturing firms in East Germany after reunification. We show that a 1-percentage-point decrease in the subsidy rate leads to a 1% decrease in manufacturing employment. We document important...

In the context of climate protection policy it has been suggested that global CO2 emissions should be reduced significantly (contraction) and that per capita emissions should gradually be equalized across countries (convergence). This paper uses a dynamic multi-region computable general...

The allocation of emission entitlements across countries is the single most controversial issue in international climate policy. Extreme positions within the policy debate range from entitlements based on current emission patterns (CEP) to equal-per-capita (EPC) allocations. Convergence (COV)...
