We present the estimated large-scale three-region DSGE model GEAR picturing Germany, the Euro Area and the Rest of the world. Compared to existing models of this type, GEAR incorporates a comprehensive fiscal block, involuntary unemployment and a complex international structure. We use the model...

Using an estimated large-scale New-Keynesian model, we assess welfare and business cycle consequences of a fiscal union within EMU. We differentiate between three different scenarios: public revenue equalisation, tax harmonisation and a centralised fiscal authority. Relative to the status quo,...

Budget-neutral tax wedge reductions rank high in the policy agenda of several EMU member states. Using a New Keynesian DSGE model of a monetary union with a complex labour market structure and a comprehensive public sector, we evaluate the macroeconomic and welfare effects of reducing the firms'...

In a dynamic, three-region environmental multi-sector general equilibrium model (called EMuSe), we find that carbon pricing generates a recession initially as production costs rise. Benefits from lower emissions damage materialize only in the medium to long run. A border adjustment mechanism...

We examine the capital market reaction to the announcement of the European Union (EU) to introduce a public tax country-by-country reporting (CbCR) regime. By employing an event study methodology, we find a significant cumulative average abnormal return (CAAR) of -0.699%, which translates into a...

Upon more than 400 judgements on direct taxation, the case law of the European Court of Justice has considerably shaped Member States' tax systems. Based on Member States' tax law adjustments in the context of four landmark rulings on corporate income taxation, we analyse whether case law is a...

What are the macroeconomic implications of re-allocating taxing rights away from source countries (where goods are produced) to market countries (where goods are consumed) and introducing minimum rates in international profit taxation? We assess this question in a dynamic macroeconomic model...
