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...

Introduction: Two next-generation pneumococcal conjugate vaccines (PCVs), a 15- and a 20-valent PCV (PCV15 and PCV20), have recently been licensed for use in adults (PCV15: EC decision Oct 14, 2021; PCV20: EC decision Feb 14, 2022). We developed a dynamical transmission model specific for Germany,...

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...

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...

In this paper, we analyze how a nationwide population-based skin cancer screening program (SCS) implemented in Germany in 2008 has impacted the number of hospital discharges following malignant skin neoplasm diagnosis (ICD–10 code C43_C44) and the malignant melanoma mortality rate (ICD–10...

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...

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...

The paper studies the current COVID-19 pandemic by applying an adapted epidemiologic model, where each individual is in one of the five states “susceptible”, “infected”, “removed”, “immune healthy” or “dead”. We extend the basic model with time-invariant transition rates...
