On the unexplained causes of the gender gap in the labour market

Purpose This paper investigates the causes of the gender gap in the labour market that cannot be explained by classical human capital theory. Design/methodology/approach To this end, the authors integrate the Gender Gap in the Labour Market Index (GGLMI), a composite index developed in previous research, with further information on some social aspects that could affect the female work commitment, directly or indirectly. In particular, the authors want to verify if family care and home duties, still strongly unbalanced against women, and the welfare system play a significant role in the gender gap. Findings Results highlight a very complex scenario, characterized by the persistence of gender inequalities everywhere, even if at different degrees, with very strong imbalances in the time spent at work in response to the family commitments. Research limitations/implications The actual determinants of gender disparities in the labour market are very difficult to identify because of the lack of adequate data and the difficulties in measuring some factors determining female behaviour. The additional information used in this research can only partially accomplish this task. Originality/value However, for the first time, this paper uses information on different aspects and causes of the gender gap, including proxies of mainly unobservable aspects, in order to achieve at least partial measurement of this phenomenon.
