Low Emission Zones Improve Air Quality and Health but Temporarily Decrease Life Satisfaction

Air pollution results in high economic costs arising from its negative impacts on human health, especially in urban areas. Driving restriction policies such as low emission zones (LEZs) are designed to improve air quality. Indeed, empirical analyses in this Weekly Report confirm that LEZs reduce traffic-related air pollution. However, the analyses also reveal unintended adverse effects on secondary ...

Discounting Behavior in Problem Gambling

Problem gamblers discount delayed rewards more rapidly than do non-gambling controls. Understanding this impulsivity is important for developing treatment options. In this article, we seek to make two contributions: First, we ask which of the currently debated economic models of intertemporal choice (exponential versus hyperbolic versus quasi-hyperbolic) provides the best description of gamblers’ discounting ...

Extracting Agency and Communion from the Big Five: A Four-Way Competition

Agency and communion are the two fundamental content dimensions in psychology. The two dimensions figure prominently in many psychological realms (personality, social, self, motivational, cross-cultural, etc.). In contemporary research, however, personality is most commonly measured within the Big Five framework. We developed novel agency and communion scales based on the items from the most popular ...

Analyzing Nonresponse in Longitudinal Surveys Using Bayesian Additive Regression Trees: A Nonparametric Event History Analysis

Increasing nonresponse rates is a pressing issue for many longitudinal panel studies. Respondents frequently either refuse participation in single survey waves (temporary dropout) or discontinue participation altogether (permanent dropout). Contemporary statistical methods that are used to elucidate predictors of survey nonresponse are typically limited to small variable sets and ignore complex interaction ...

Heteroskedastic Proxy Vector Autoregressions: Testing for Time-Varying Impulse Responses in the Presence of Multiple Proxies

We propose a test for time-varying impulse responses in heteroskedastic structural vector autoregressions that can be used when the shocks are identified by external proxy variables as a group. The test can be used even if the shocks are not identified individually. The asymptotic analysis is supported by small sample simulations which show good properties of the test. An investigation of the impact ...

Mentoring as a Grassroots Effort for Integrating Refugees – Evidence from a Randomised Field Experiment

About 80 million people were displaced worldwide at the end of 2020. To support this highly vulnerable group, in recent years, local bottom-up initiatives proliferated to support refugee integration in hosting communities. This study examines a network intervention for refugees in collaboration with a social start-up whose mission is to match refugees and local volunteers to form friendships. We apply ...

Measurement Equivalence in Probability and Nonprobability Online Panels

Nonprobability online panels are commonly used in the social sciences as a fast and inexpensive way of collecting data in contrast to more expensive probability-based panels. Given their ubiquitous use in social science research, a great deal of research is being undertaken to assess the properties of nonprobability panels relative to probability ones. Much of this research focuses on selection bias, ...

Sexual and Gender Minority (SGM) Research Meets Household Panel Surveys: Research Potentials of the German Socio-Economic Panel and Its Boost Sample of SGM Households

There are numerous challenges to studying structural inequality in sexual and gender minority (SGM) populations, from the difficulty of obtaining a representative sample to issues comparing data across populations. This data brief illustrates how the largest household panel survey in Germany, the German Socio-Economic Panel (SOEP), and its recent nationwide boost sample of SGM households, Sample Q, ...

Facebook Shadow Profiles

Data is often at the core of digital products and services, especially when related to online advertising. This has made data protection and privacy a major policy concern. When surfing the web, consumers leave digital traces that can be used to build user profiles and infer preferences. We quantify the extent to which Facebook can track web behavior outside of their own platform. The network of engagement ...

Comparison of Local Projection Estimators for Proxy Vector Autoregressions

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 ...
