In addition to efficiency standards and consumer information, car-related taxes constitute one of three pillars of the European Commission¿s strategy to reduce CO2 emissions from passenger cars. A longstanding question concerns the effectiveness of such taxes in determining the car-purchasing...

This paper presents evidence that the accumulating cost of Germany’s ambitious plan to transform its system of energy provision – the so-called Energiewende – is butting up against consumers’ willingness-to-pay (WTP) for it. Following a descriptive presentation that traces the German...

This paper looks into the 'fine print' of boosting for economic forecasting. By using German industrial production for the period from 1996 to 2014 and a data set consisting of 175 monthly indicators, we evaluate which indicators get selected by the boosting algorithm over time and four...

Interaction effects capture the impact of one explanatory variable x1 on the marginal effect of another explanatory variable x2. To explore interaction effects, so-called interaction terms x1x2 are typically included in estimation specifications. While in linear models the effect of a marginal...

Drawing on household data from Germany, this study econometrically analyzes the determinants of automobile ownership, focusing specifically on the extent to which decreases in family size translate into changes in the number of cars at the national level. Beyond modeling several variables over...

The use of large datasets for macroeconomic forecasting has received a great deal of interest recently. Boosting is one possible method of using high-dimensional data for this purpose. It is a stage-wise additive modelling procedure, which, in a linear specification, becomes a variable selection...

Rebound effects measure the behaviorally induced offset in the reduction of energy consumption following efficiency improvements. Using both panel estimation and quantile regression methods on household travel diary data collected in Germany between 1997 and 2009, this study investigates the...

Business climate indicators are used to receive early signals for turning points in the general business cycle. Therefore methods for the detection of turning points in time series are required. Estimations of slopes of a smooth component in the data can be calculated with local polynomial...

Drawing on individual-level mobility data from Germany between 1996 and 2009, this analysis econometrically investigates the determinants of automobile, public transit, and nonmotorized travel. The paper explores whether gender plays a role in determining the relative use of motorized and...
