Several approaches for subset recovery and improved forecasting accuracy have been proposed and studied. One way is to apply a regularization strategy and solve the model selection task as a continuous optimization problem. One of the most popular approaches in this research field is given by...

Stock picking is the field of financial analysis that is of particular interest for many professional investors and researchers. In this study stock picking is implemented via binary classification trees. Optimal tree size is believed to be the crucial factor in forecasting performance of the...

This paper contributes to the analysis of policy measures that attempt to reduce health care expenditures of insurers. We examine the impact of a cash bonus program for preventive health behavior of a German health insurer on prevention effort and health care expenditures using a unique...

In a randomized controlled trial involving 700 obese persons assigned to three experimental groups, we test whether financial incentives have heterogeneous effects on weight reduction. While two treatment groups obtain EUR 150 and EUR 300, respectively, for achieving an individually-assigned...

This study explores the impact an exogenous improvement in childhood health has on later-life outcomes. Using extensive and detailed register data from the Swedish Interdisciplinary Panel, we follow individuals exposed to the introduction of the first vaccine against polio in Sweden (birth...

Starting in 2009, the German state of Saxony distributed sports club membership vouchers among all 33,000 third graders in the state. The policy's objective was to encourage them to develop a long-term habit of exercising. In 2018, we carried out a large register-based survey among several...

From a theoretical viewpoint, there can be market failures resulting in an underprovision of occupational health and safety. Works councils may help mitigate these failures. Using establishment data from Germany, our empirical analysis confirms that the incidence of a works council is...
