This dissertation presents four independent papers that advance experimental methods and test theories on saving using experimentally elicited characteristics. The first two papers test two behavioral theories on precautionary saving based on the characteristics loss aversion and prudence by...

We show how the rootogram - a graphical tool associated with the work of J. W. Tukey and originally used for assessing goodness of fit of univariate distributions - can help to diagnose and treat issues such as overdispersion and/or excess zeros in regression models for count data. Two empirical...

Feed-in tariffs under the Renewable Energy Sources Act, the so-called Erneuerbare-Energien-Gesetz (EEG), have triggered a massive expansion of electricity from renewable energy sources in Germany over the last decade.
