We develop a tractable macroeconomic model with employment risk and labor market search in order evaluate the effects of labor market reform on unemployment, growth, and welfare. The model has a large number of risk-averse households who can invest in risk-free physical capital and risky human...

This paper analyzes the impact increased offshoring has on labor income risk. It is therefore distinct from a large number of studies explaining the level effects of globalization on the labor market in that it takes a look at effects on second moments, i.e. the variance of incomes. It provides...

This paper analyses the link between human capitaland information technology(IT ) in the service production process. The analysis is based on 1994 cross-sectional data for 1929 German. Firms drawn from the first wave of the Mannheim Service Innovation Panel (MIP-S). Factor demand functions are...

We explore the design of self-financing tax-subsidy schemes to solve hold-up problems in environmental regulation. The announcement of the tax rate seems to be preferable to solve hold-up problems with respect to the investment in environmental R&D. In contrast, only the announcement of the...

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

The paper characterises the building blocks of a framework to enforce antipredation rules and subsequently evaluates selected enforcement options in a Cournot-type duopoly predation model. Differentiating between a no rule approach, an ex ante approach and two ex post approaches, it is shown...

We present a decomposition approach for integrated assessment modeling of climate policy based on a linear approximation of the climate system. Our objective is to demonstrate the usefulness of decomposition for integrated assessment models posed in a complementarity format. First, the...

In the tax policy debate, differentiation of value-added taxes is often justified by distributional concerns. Our quantitative analysis for Germany indicates that such concerns are misplaced. We find that the abolition of VAT differentiation has only negligible redistributive effects. Instead,...

This paper explores the impact of R&D subsidies on the concentration of R&D in an economy. First, governments are often criticized of subsidizing predominantly larger firms and thus contribute to persistence of leadership in markets and higher barriers to entry, and, hence, reduced competition...
