We study the impact of broadband availability on firms’ total factor productivity (TFP) using German firm-level data between 2010 and 2015. We adopt a control function approach to causally identify and separately estimate productivity for 46 two-digit manufacturing and service sectors. Over the sample period, broadband availability, measured by 16 Mbps transmission rates, more than doubled in German ...
Given the high number of refugee children and adolescents around the globe, it is critical to determine conditions that foster their adaptation in the receiving country. This study investigated the psychological adaptation of recently arrived adolescent refugees in Germany. We focused on whether psychological adaptation reflects the organizational approach taken by the school that refugee adolescents ...
Different local projection (LP) estimators for structural impulse responses of proxy vector autoregressions are reviewed and compared algebraically and with respect to their small sample suitability for inference. Conditions for numerical equivalence and similarities of some estimators are provided. Two generalized least squares (GLS) projection estimators are found to be more accurate than the other ...
Public debates and current research on “digitalization” suggest that digital technologies could profoundly transform the world of work. While broad claims are common in these debates, empirical evidence remains scarce. This calls for reliable data for empirical research and evidence-based policymaking. We implemented a data module in the Socio-Economic Panel to gather information on digitalization ...
Negative interest rates remain a controversial policy for central banks. We study a novel signalling channel and ask under what conditions negative rates should exist in an optimal policymaker’s toolkit. We prove two necessary conditions for the optimality of negative rates: a time-consistent policy setting and a preference for policy smoothing. These conditions allow negative rates to signal policy ...
Several studies have suggested that the rank-order stability of personality increases until midlife and declines later in old age. However, this inverted U-shaped pattern has not consistently emerged in previous research; in particular, a recent investigation implementing several methodological advances failed to support it. To resolve the matter, we analyzed data from two representative panel studies ...
We examine the relationship between parenting activities and center-based care using time diary and survey data for mothers in Germany. While mothers using center-based care spend significantly less time in the presence of their child, we find that differences in the time spent on specific activities such as reading, talking, and playing with the child are relatively small or zero. The pattern of results ...
Equivalence Scales are a tool for removing the heterogeneity of household sizes in the measurement of inequality, and affect poverty assessments and poverty lines. We address the disadvantage that poor households may suffer due to their reduced ability to share goods within the household. This disadvantage is important to estimate and embed in standard analysis, as it seems to have a substantial quantitative ...
Rent control is a highly debated social policy that has been omnipresent since World War I. Since 2010s, it has been experiencing a true renaissance, for many cities and countries facing housing shortage are desperately looking for solutions of the chronic housing shortage and direct their attention to controlling housing rents and to other restrictive policies. Is rent control useful or does it create ...
