On normal days, the temperature decreases with altitude, allowing air pollutants to rise and disperse. During inversion episodes, a warmer air layer at higher altitude traps pollutants close to the ground. We show how readily available NASA satellite data on vertical temperature profiles can be...

"Matching" is a statistical technique used to evaluate the effect of a treatment by comparing the treated and non-treated units in an observational study. Matching provides an alternative to older estimation methods, such as ordinary least squares (OLS), which involves strong assumptions that...

This paper evaluates the impact of a vocational training programme on the labour market outcomes of unemployed youth in Latvia. The programme is part of the Youth Guarantee scheme for the period 2014-2020, the largest action launched by the European Union to reduce youth unemployment rate and to...

This paper discusses pairing double/debiased machine learning (DDML) with stacking, a model averaging method for combining multiple candidate learners, to estimate structural parameters. We introduce two new stacking approaches for DDML: short-stacking exploits the cross-fitting step of DDML to...

This paper evaluates the impact of a vocational training programme on the labour market outcomes of unemployed youth in Latvia. The programme is part of the Youth Guarantee scheme for the period 2014-2020, the largest action launched by the European Union to reduce youth unemployment rate and to...

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

We use administrative tax data to analyze the cumulative, long-run effects of California's 2004 Paid Family Leave Act (CPFL) on women's employment, earnings, and childbearing. A regression-discontinuity design exploits the sharp increase in the weeks of paid leave available under the law. We...

Do ruling parties positively discriminate in favour of their own constituencies in allocating public resources? If they do, do they gain electorally in engaging in such a practice? This paper tests whether partisan alignment exists in the allocation of funds for India's largest social protection...

This paper compares the net fiscal position (NFP) of immigrants versus natives using data from the European Survey on Living Conditions (EU-SILC) for the period 2007-2015. By employing a quantile regression approach, we find that European and non-European migrants have a different fiscal...

The value of a statistical life (VSL) is a very controversial topic, but one which is essential to the optimization of governmental decisions. Indeed, our society faces any number of risks (health, transportation, work, etc.) and, as resources are limited, their complete elimination is...
