RESUMO
Since WWII, the two most important global trends in family planning have been fertility decline and abortion liberalisation. But are they related? Specifically: Does abortion liberalisation affect changes in fertility rates? The demographic literature has yet to answer this important question and instead offers two opposing predictions. Some studies argue that liberalisation of this medical procedure reduces fertility rates. By contrast, others note that such legal reforms may merely have an average, negligible effect on fertility levels. We adjudicate between the two approaches by conducting, in our view, the most comprehensive global, quantitative analysis of the relationship between those legal reforms and changing fertility rates. The analysis relies on two-way fixed models and three different indicators of abortion policy liberalism created by independent research teams to estimate the relationship between abortion liberalisation and total fertility changes. The data cover 185 independent states between 1970 and 2019. Fertility rates are significantly related to average public education levels and alternative contraceptive use. Using multiple model specifications, however, abortion reforms do not have a robust association with the outcome.

RESUMO
We use Spanish military records stemming from the late-19th to the mid-20th century to assess internal migrants' self-selection. We find that migrants were, on average over the whole period, around one centimeter taller than non-migrants, and in the booming 1920s, the height advantage of movers reached three centimeters. The positive self-selection was larger for migrants originating in poorer provinces and traveling longer distances. A further finding is that migrants were positively selected in terms of literacy and socio-economic status according to their occupation. Professionals were most likely to have migrated internally and farmers least.
