Drawing on panel data from Germany, this paper analyzes the correlates of happiness, with an eye toward isolating the role of parenthood over the lifecycle. The analysis couples a panel quantile regression with an empirical specification that captures different phases of parenthood, from the...

The overestimation of willingness-to-pay (WTP) in hypothetical responses is a well-known finding in the literature. Various techniques have been proposed to remove or, at least, reduce this bias. Using about 30,000 responses on WTP for a variety of power mixes from a panel of 6,500 German...

Using household travel diary data collected in Germany between 1997 and 2012, we employ an instrumental variable (IV) approach that enables us to consistently estimate both fuel price and efficiency elasticities at once. The aim is to gauge the relative impacts of fuel economy standards and fuel...

Ziel dieser Studie ist die Schätzung des Energieverbrauchs privater Haushalte in Deutschland für die Jahre 2011 bis 2013 mittels einer Stichprobenerhebung, die mittlerweile auf einem aus rund 15 000 Haushalten bestehenden repräsentativen Panel des forsa-Instituts basiert. Die Haushalte werden...

We identify the causal effect of a reduction in military personnel on a number of socioeconomic indicators within the periphery of the military base. The base realignments and closures (BRACs) within the German armed forces is an exogenous source of variation that allows for the estimation of...

This note investigates the pass-through of global Brent oil notations to fuel prices across the oligopoly of retail majors in Germany. We assemble a high-frequency panel data set that encompasses millions of price observations and allows us to distinguish effects by brand. Upon establishing a...

Sample selection models, variants of which are the Heckman and Heckit models, are increasingly used by political scientists to accommodate data in which censoring of the dependent variable raises concerns of sample selectivity bias. Beyond demonstrating several pitfalls in the calculation of...

This note demonstrates that in applied regression analysis, the variance of a coefficient of interest may decrease from the inclusion of a control variable, contrasting with Clarke’s assertion (2005, 2009) that the variance can only increase or stay the same. Practitioners may thus be well...

Using detailed data originating from several hundred households of the German Residential Energy Survey (GRECS), this paper empirically investigates the returns on investment in home-equipped photovoltaics (PV) installations. We find that these returns were particularly high in the years 2009 to...
