This paper investigates the economic and environmental effects of pay-as-you-throw (PAYT) waste programs. Using a newly constructed longitudinal dataset of Italian municipalities and a staked-by-event design, we obtain three main findings: (i) PAYT programs significantly reduce total waste...

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...

Recently, there has been a growing interest in newly developed econometric tools to conduct counterfactual analysis when a treated unit experiences a policy intervention, and an artificial control group has to be constructed. Adopting novel penalized synthetic control methods, we quantify the...

We exploit a recent state-level reform in Germany that granted parents the right to decide on the highest secondary school track suitable for their child, changing the purpose of the primary teacher's recommendation from mandatory to informational. Applying a disaggregated synthetic control...

We investigate the unemployment pathway to retirement in Germany and study the causal effects of two early retirement reforms. Reform 1 (NRA) increased normal retirement age stepwise from 60 to 65. Simultaneously, it became possible to use early retirement with benefit discounts. Reform 2 (ERA)...

One of the perceived advantages of difference-in-differences (DiD) methods is that they do not explicitly restrict how units select into treatment. However, when justifying DiD, researchers often argue that the treatment is "quasi-randomly" assigned. We investigate what selection mechanisms are...

We use (donut) regression discontinuity design and difference-in-differences estimators to estimate the impact of a one-shot hiring subsidy targeted at low-educated unemployed youths during the Great Recession recovery in Belgium. The subsidy increases job-finding in the private sector by 10...

Aiming to reduce the number of brown (polluting) cars on the road, several countries currently promote the purchase and use of green (emission-free) cars through financial and non-financial incentives. We study how such incentives affect consumers who continue to drive brown cars. Using a simple...

We identify and examine a novel welfare channel of fuel economy standards through the in-teraction with public transit and households' location choices. A stricter emission standard for cars decreases the marginal cost of driving and triggers a shift in modal choice from public to private...

This paper exploits the introduction of the German carbon tax in 2021 as well as excise tax rebates on fuel in both France and Germany, consecutive to the 2022 oil crisis, to infer how fuel tourism responds to changes in relative prices. Based on French high-frequency transaction-level data...
