Using machine learning methods in a quasi-experimental setting, I study the heterogeneous effects of introducing waste prices - unit prices on household unsorted waste disposal - on waste demands and social welfare. First, using a unique panel of Italian municipalities with large variation in prices and observables, I show that waste demands are nonlinear. - find evidence of constant elasticities at ...

We analyse the impact of transportation infrastructure capital and its maintenance status on regionaleconomic production, exploiting panel data on the German county level (N = 401) between 2007 and2016 in a spatial translog production function. Various SLX and SDEM models are estimated usingFGLS and GMM estimators accounting for endogeneity. We find a positive impact of the transportinfrastructure ...
We examine whether the financial strength of companies, in particular, small and medium-sized enterprises (SMEs) is causally linked to the award of a public procurement contract (PP), especially in the environmentally friendly “green” area (GPP). For this purpose, we build a combined procurement company data set from the Tenders Electronic Daily (TED) and the SME database AMADEUS, which includes ten ...
This study analyzes the causal effect of an increase in the retirement age on health. We exploit a sizable cohort-specific pension reform for women using two complementary empirical approaches - a Regression Discontinuity Design and a Difference-in- Differences approach. The analysis is based on official records covering all individuals insured by the public health system in Germany and including all ...
