Do immigrants shield the locals? Exposure to COVID-related risks in the European Union.

This article investigates the relationship between immigration and the exposure of native workers to health and labor-market risks arising from the COVID-19 pandemic in Europe. Using various measures of occupational risks based on European Union labor force survey data, we find that immigrant workers, especially those from lower-income member countries in Eastern Europe or from outside the EU, face greater exposure than their native-born peers to both income and health-shocks related to COVID-19. We also show that native workers living in regions with a higher concentration of immigrants are less exposed to some of the income and health risks associated with the pandemic. To assess whether this relationship is causal, we use a Bartik-type shift-share instrument to control for potential bias and unobservable factors that would lead migrants to self-select into more vulnerable occupations across regions. The results show that the presence of immigrant workers has a causal effect in reducing the exposure of native workers to various risks by enabling the native-born workers to move into jobs that could be undertaken from the safety of their homes or with lower face-to-face interactions. The effects on the native-born population are more pronounced for high-skilled workers than for low-skilled workers, and for women than for men. We do not find significant effect of immigration on wages and employment-indicating that the effects are mostly driven by a reallocation of natives from less safe jobs to safer jobs.

The effect of height on earnings: Is stature just a proxy for cognitive and non-cognitive skills?

While taller workers are regularly observed to earn more, there is debate concerning the independent contribution of stature to labor earnings. This study investigates the degree to which the association of height and earnings in Pakistan is independent of other cognitive and socio-emotional skills. Next, the relationship between height and earnings is explored when measures of cognitive ability and an index of socio-emotional capacity are included separately. The paper finds only a modest attenuation in the contribution of height to earnings after controlling for additional dimensions of human capital, suggesting that height provides independent information on labor productivity. This result is robust to treating height as endogenous. The paper also examines non-linearities in the relationship between height and earnings. In contrast to results from relatively few other contributions to research on this non-linear relationship, height is associated with earnings only when an individual is taller than the median height. This lends some support to the role of status and confidence in the yet unresolved question as to the relative contribution of direct and indirect influence of height on earnings.

Is consanguinity an impediment to child development?

Marriages between blood relatives-also known as consanguineous unions-are widespread in North Africa, Central and West Asia, and South Asia. Researchers have suggested that consanguinity has adverse effects on child development, but assessing its impact is not straightforward, as the decision to marry a relative might be endogenous to other socio-economic factors. Using a unique data set collected in rural Pakistan, this paper assesses the extent to which consanguinity is linked to children's cognitive and physical development. It exploits grandfathers' land ownership (current and past) and maternal grandparent mortality to identify the effect of endogenous consanguinity on child development. Children born into consanguineous unions have lower cognitive scores, lower height-for-age, and a higher likelihood of being severely stunted. More importantly, adverse effects are greater after accounting for the endogeneity of consanguinity, suggesting that impacts on child development are substantial, and likely to be larger than suggested in previous studies.
