This paper is devoted to the study of diversification and specialization influence on one of the main indicators of Russian labour market, the unemployment growth. The purpose of the work is to find out which effects dominate in the Russian regions, Marshallian or Jacobs, and whether this...

We exploit the variation in admission cutoffs across colleges at a leading Indian university to estimate the causal effects of enrolling in a selective college on cognitive attainment, economic preferences, and Big Five personality traits. Using a regression discontinuity design, we find that...

We analyse how the financial support for long-term elderly care affects the household’s propensity to save. Using the difference-in-differences estimator, we investigate the 2002 Scottish reform, which introduced free formal personal care for all the Scottish elderly aged 65 and above. We find...

In this paper we use a large official employer-employee dataset, which includes almost the whole universe of business firms, to document and decompose the rising graduates postgraduates’ wage differentials in Portugal. Using a non-parametric matching exercise, we pay particular attention to...

Recent studies have proposed causal machine learning (CML) methods to estimate conditional average treatment effects (CATEs). In this study, I investigate whether CML methods add value compared to conventional CATE estimators by re-evaluating Connecticut's Jobs First welfare experiment. This...

We derive nonparametric sharp bounds on average treatment effects with an instrumental variable (IV) and use them to evaluate the effectiveness of the Job Corps training program for disadvantaged youth. We focus on the population average treatment effect (ATE) and the average treatment effect on...

We investigate the impact of a policy reform, which introduced free formal personal care for all those aged 65 and above, on caregiving behaviour. Using a difference-indifferences estimator, we estimate that the free formal care reduced the probability of co-residential informal caregiving by...

A common problem with differences-in-differences (DD) estimates is the failure of the parallel-trend assumption. To cope with this, most authors include polynomial (linear, quadratic…) trends among the regressors, and estimate the treatment effect as a once-in-a-time trend shift. In practice...

Peacetime military service has both positive and negative effects on human capital. While it depreciates academic abilities it also enhances non-cognitive skills. The net effect of conscription is hard to identify due to issues of self-selection, endogenous timing and omitted variables bias. We...

This study examines the impact that over-education has on the earnings of private and public sector workers in Trinidad and Tobago. Using individual person's data from the Continuous Sample Survey of the Population (CSSP) for the period 1991-2015, the returns of over-educated workers is...
