This paper investigates the relationship between wealth, ageing and saving behaviour of private households by using pooled cross sections of German consumption survey data. Different components of wealth are distinguished, as their impact on the savings rate is not homogeneous. On average, the...

We analyze the pass-through of cost changes to retail tariffs in the German electricity market over the 2007 to 2014 period. We find an average pass-through rate of around 60%, which significantly varies with demand factors: while the pass-through rate to baseline tariffs, where firms have...

In 2008, the European Commission investigated E.ON, a large and vertically integrated electricity company, for the alleged abuse of a joint dominant position by strategically withholding generation capacity. The case was settled after E.ON agreed to divest 5,000 MW generation capacity as well as...

This paper empirically investigates the relevance of liquidity constraints and excess sensitivity in intertemporal household consumption. Using a pseudo panel that has been constructed on rich German consumption survey data, we estimate the consumption responses to permanent and transitory...

We investigate the welfare impact of parallel imports using a large panel data set containing monthly information on sales, ex-factory prices, and further product characteristics for all 700 anti-diabetic drugs sold in Germany between 2004 and 2010. We estimate a two-stage nested logit model of...

We study the impact of broadband availability on firms’ total factor productivity (TFP) using German firm-level data between 2010 and 2015. We adopt a control function approach to causally identify and separately estimate productivity for 46 two-digit manufacturing and service sectors. Over...

We provide an evaluation of the impact of public subsidy schemes that aimed to support the development of basic broadband infrastructure in rural areas of Germany. Such subsidies are subject to state aid control by the European Commission (EC). While the EC increasingly recognises the role of...

There is by now a lot of evidence showing a sharp increase in cross-sectional wage and earnings inequality during the 2000s in Germany. Our study is the first to decompose this cross-sectional variance into its permanent and transitory parts for years beyond 2000. Using data from the German...

This paper empirically investigates distributional and welfare effects of Germany's year 2000 income tax reform. The reform is simulated in an ex-ante behavioral microsimulation approach. Dead weight loss of changes in capital income taxation is estimated in a structural model for household...

This paper empirically investigates the effects of differential income taxation on households' portfolio choice and asset allocation applying a two-stage budgeting model of asset demand to German survey data. The model is structured into the discrete asset choice and the continuous asset choice,...
