Multivariate Adaptive Regression Spline (MARS) is a simple and powerful non-parametric machine learning algorithm that automatizes the selection of non-linear terms in regression models. In this study, we propose using MARS in a spatial regression framework to account for potential non-linearities and spatial effects in spatial regression models. Using a relatively large data set of 17,000 dwellings ...
We construct a global index of epidemic news based on text analysis of newspapers from 17 countries. We apply the index to study the economic consequences of epidemics on the world economy in structural vector autoregressions. Epidemic shocks exert significantly and persistently negative effects on output and prices that last for up to two years. There is no quick recovery and no overshooting. The ...
Subjective well-being (SWB) is a complex multidimensional construct with manifold positive implications. However, research on the structure of SWB faces some challenges, as empirical results regarding the popular tripartite model of SWB are inconclusive, and domain satisfaction is often not sufficiently considered when analyzing the structure of SWB. Furthermore, since the different SWB components...
The German economy has returned to a recovery course following a slight recession over the winter. Although the war in Ukraine, record inflation, and feared gas shortages have taken their toll on the German economy, a drastic slump failed to materialize. The German economy remained relatively unscathed, only experiencing a slight recession over the past six months; in the final quarter of 2022 and ...
Heat pumps are a key technology for reducing fossil fuel use in the heating sector. A transition to heat pumps implies an increase in electricity demand, especially in cold winter months. Using an open-source power sector model, we examine the power sector impacts of a massive expansion of decentralized heat pumps in Germany in 2030, combined with buffer heat storage of different sizes. Assuming that ...
This article presents the new linked employee-employer study of the Socio-Economic Panel (SOEP-LEE2), which offers new research opportunities for various academic fields. In particular, the study contains two waves of an employer survey for persons in dependent work that is also linkable to the SOEP, a large representative German annual household panel (SOEP-LEE2-Core). Moreover, SOEP-LEE2 includes ...
This study investigates whether public procurement mitigates or exacerbates innovative enterprises’ financial constraints. We distinguish between general and environmentally beneficial innovative enterprises. Theory suggests that the treatment effects of public procurement, particularly when mediated by the demand-pull effect, may lower a company’s funding constraints for innovation. We test this theory ...
