Currently there is little practical advice on which treatment effect estimator to use when trying to adjust for observable differences. A recent suggestion is to compare the performance of estimators in simulations that somehow mimic the empirical context. Two ways to run such "empirical Monte...

Difference-in-difference estimation is a popular tool to gauge the effects of economic policies. In recent years, many papers have applied this tool to the German deregulation of the crafts sector in 2004 to draw lessons regarding the economic effects of occupational licensing. However, a...

We investigate the finite sample performance of causal machine learning estimators for heterogeneous causal effects at different aggregation levels. We employ an Empirical Monte Carlo Study that relies on arguably realistic data generation processes (DGPs) based on actual data. We consider 24...
