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...

Society drifts apart in many dimensions. Economists focus on income of the poor and rich and the distribution of income but a broader spectrum of dimensions is required to draw the picture of multiple facets of individual life. In our study of multidimensional polarization we extend the income...

The economic literature has largely overlooked the importance of repeat and circular migration. The paper studies this behavior by analyzing the number of exits and the total number of years away from the host country using count data models and panel data from Germany. More than 60% of migrants...

It is time which enables and restricts individual activities and is a further brick to a more comprehensive picture of individual well-being. In our study we focus on a prominent part...

Empirical analyses using cross-sectional and panel data found significantly higher levels of job satisfaction for self-employed than for employees. We argue that those estimates in previous studies might be biased by neglecting anticipation and adaptation effects. For testing we specify several...

In this paper we study the economic effects of risk attitudes, time preferences, trust and reciprocity while we compare natives and second generation migrants. We analyze an inflow sample into unemployment in Germany, and find differences between the two groups mainly in terms of risk attitudes...

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...
