Using a stacked differences-in-differences approach, we study the effects of Low Emission Zones (LEZs) in Germany. The implementation of stage 1 and 2 LEZs, which banned the most pollution-intensive vehicles from city centers, significantly reduced PM10 concentrations. The most restrictive third...

In response to COVID-19, dramatic safer-at-home policies were implemented. The understanding of their impacts on social distancing, travel and pollution is in its infancy. We pair a differences-in-differences framework and synthetic control methods with rich cellular tracking and high frequency...

Using administrative DVLA data matched with micro-data from Understanding Society - the UK Household Longitudinal Study we estimate income-related inequalities in ownership of vehicles with a set of safety features and we apply a regression-based decomposition method for rank-dependent...

We study the effects of a large car scrappage scheme in Germany on new car purchases and local air quality by combining vehicle registration data with data on local air pollutant emissions. For identification we exploit cross-sectional variation across districts in the number of cars eligible...

This paper analyzes how life-cycle unemployment of former apprentices depends on the size of the training firm. We start from the hypotheses that the size of training firms reduces long-run cumulated unemployment exposure, e.g. via differences in training quality and in the availability of...

In this paper we provide the first analysis of whether rushed privatizations, usually carried out under fiscal duress, increase or decrease firms' efficiency, scale of operation (size) and employment. Using a large panel of firm-level data from Poland over 1995-2015, we show that rushed...

This paper explores how a minimum wage affects a firm's behavior with a competitive labor market and an uncertain export cost. The model provides several novel insights which are consistent with recent empirical evidence. Thus, a minimum wage increases an exporter's foreign-market size and may...
