We evaluate German purchase subsidies for battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs) using data on new vehicle registrations in Germany during 2015-2022. We account for confounding time trends and interacting EU-level CO2 standards using neighboring countries as a control group. The program was cost-ineffective, as only 40% of BEV and 25% of PHEV registrations were ...
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 ...
How does previous exposure to massive immigrant inflows affect concerns about current immigration and the integration of refugees? To answer this question, we investigate attitudes toward newcomers among natives and previous immigrants. In areas that in the 1990s received higher inflows of immigrants of German origin—so-called ethnic Germans—native Germans are more likely to believe that refugees are ...
We study the effectiveness, spillovers, and well-being effects of low emission zones in Germany, an emission-intensity-based driving restriction rapidly growing in popularity. Using regression discontinuity and group-time difference-in-differences designs, we show that previous estimates of the policy’s impact on traffic-related air pollution significantly underestimate its effectiveness. We provide ...
Panel data has become the gold standard for causal assessments of complex human behaviour in quantitative social science. The objective of this review is to examine and discuss how panel data and related methods contribute to the identification of causal relationships in spatial mobility research. We illustrate this by providing a succinct overview of recent progress in spatial mobility research, drawing ...
