Evidence during the nineties about the response of real wages to shocks highlights that this response is substantially lower in European countries than in the United States and that there are important differences among European countries. Which are the reasons that explain these different reactions? In this paper, we apply meta-analytical techniques in order to provide a quantitative summary of the ...

Attitudes towards the Euro: An Empirical Study Based on the German Socio-Economic Panel (SOEP)

This paper investigates changing attitudes towards the euro over time in Germany using longitudinal micro-data from the German Socio Economic Panel Study. We observe that a large part of the German population was worried about the new currency both before and after its introduction. Social psychological theories provide insight into these attitudes. Concerns regarding the euro are apparently connected ...

The Environmental and Economic Effects of European Emissions Trading

In this article, we analyse the effects of emissions trading in Europe, with special reference to Germany. We look at the value of the flexibility gained by trading compared to fixed quotas. The analysis is undertaken with a modified version of the GTAP-E model using the latest GTAP version 6 database. It is based on the national allocation plans (NAP) as submitted to and approved by the EU. We find ...

Apply with Caution: Introducing UK-Style In-Work Support in Germany

Estimates of the labour supply effects of recent UK reforms in the area of direct taxes and benefits show that policy can have significant influence on the level of employment. We confirm this in a simulation of an in-work support system introduced into the German tax and benefit system. Our simulation results suggest that introducing in-work tax credits in Germany would increase the employment of ...

Testing the Effectiveness of French Work-sharing Reform: A Forecasting Approach

The macroeconomic impact of the French work-sharing reform of 2000 (a reduction of standard working hours in combination with wage subsidies) is analysed. Using avector error correction model (VECM) for several labour market variables, as well as inflation and output, out-of-sample forecasts for 2000/2001 are produced. A comparison of these forecasts - which serve as a benchmark simulation without ...

One specification includes EMU industrial production and a real external value based on consumer prices, the other two use different EMU investment aggregates, the orresponding real external ...

Traditional issues in electricity sector benchmarking are addressed, such as the role of scale effects and optimal utility size, as well as new evidence specific to the situation in Germany. Labour, capital, and peak load capacity are used as inputs, and units sold and the ...

Agglomeration and Tax Competition

Tax competition may be different in "new economic geography settings" compared to standard tax competition models. If the mobile factor is completely agglomerated in one region, it earns an agglomeration rent which can be taxed. Closer integration first results in a "race to the top" in taxes before leading to a "race to the bottom". We reexamine these issues in a model that produces stable equilibria ...
