The reciprocal relationship between psychiatric and substance use disorders is well-known, yet it remains largely unknown whether mental health morbidity causally leads to addictive behaviours. This paper utilises a fixed effects instrumental variables model, which is identified by time-varying...

The growth of self-employment and in particular gig work may explain part of the declining fertility rates observed in many countries. This study examines this question drawing on longitudinal data to compare women’s fertility, proxied by maternity leave uptake, when self-employed or wage...

The growth of novel flexible work formats raises a number of questions about their effects upon health and the potential public policy implications. However, answering these questions is hampered by data and identification constraints. This is the first paper that draws on comprehensive...

This paper studies the dynamics of fertility in 180 countries in the period 1950-2015 and investigates the determinants of the onset of fertility transitions. The application of Phillips and Sul's (2007) test to fertility rates provides evidence of convergence in three groups of countries. 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...

This paper contributes to the literature on overeducation by empirically investigating the wage penalty of job-education mismatch among Ph.D. holders who completed their studies in Italy; a country where the number of new doctoral recipients has dramatically increased over recent years while...

This essay delivers two main innovations with respect to the existing literature. First, and foremost, by extending the work of Nicaise (2010) relative to the reservation wage to the case of overeducation, we propose a statistical test to discriminate between alternative theoretical...

This is the first study to investigate whether age gaps between classmates (that is, relative age) affect life-satisfaction gaps in adolescence. To this end, we analyse data from the multi-country Health Behaviour in School-Aged Children (HBSC) survey. We find evidence that relative age...

Historically, the Spanish labor market has been quite unstable. The unexpected arrival of COVID-19 in 2020 has stressed these vulnerabilities. In this paper, we analyze the immediate impact of the pandemic on Spanish labor market outcomes. We find that, during the lockdown period, individuals...
