This paper investigates the reversibility of the effects of transport infrastructure investments, based on a programme that removed much of the rail network in Britain during the mid-20th Century.We find that a 10% loss in rail access between 1950 and 1980 caused a persistent 3% decline in local population relative to unaffected areas, implying that the 1 in 5 places most exposed to the cuts saw 24 percentage points less population growth than the 1 in 5 places that were least exposed.The cuts reduced local jobs and shares of skilled workers and young people.
Human capital—that is, resources associated with the knowledge and skills of individuals—is a critical component of economic development 1 , 2 . Learning metrics that are comparable for countries globally are necessary to understand and track the formation of human capital. The increasing use of international achievement tests is an important step in this direction 3 . However, such tests are administered primarily in developed countries 4 , limiting our ability to analyse learning patterns in developing countries that may have the most to gain from the formation of human capital. Here we bridge this gap by constructing a globally comparable database of 164 countries from 2000 to 2017. The data represent 98% of the global population and developing economies comprise two-thirds of the included countries. Using this dataset, we show that global progress in learning—a priority Sustainable Development Goal—has been limited, despite increasing enrolment in primary and secondary education. Using an accounting exercise that includes a direct measure of schooling quality, we estimate that the role of human capital in explaining income differences across countries ranges from a fifth to half; this result has an intermediate position in the wide range of estimates provided in earlier papers in the literature 5 – 13 . Moreover, we show that average estimates mask considerable heterogeneity associated with income grouping across countries and regions. This heterogeneity highlights the importance of including countries at various stages of economic development when analysing the role of human capital in economic development. Finally, we show that our database provides a measure of human capital that is more closely associated with economic growth than current measures that are included in the Penn world tables version 9.0 14 and the human development index of the United Nations 15 .
During the late 19th century, the increasing popularity of pudding in England, along with the outbreak of phylloxera plague in French vineyards had an unintended effect in the agrarian economy of Greece. In particular, these events escalated the international demand and production of currants in Greece during the 1870s, causing an unprecedented positive shock that was transmitted through trade in the agricultural population. Using novel data from historical archives, we explore how this exogenous event affected investment towards human capital. Consistent with expectations, in an agrarian economy that specializes in unskilled labour-intensive agricultural goods, this shock had a negative effect on human capital formation.
Asylum seekers who migrate from developing countries to Europe frequently experience victimization events during their journey. The consequences of these events for their economic integration into destination countries are not yet well explored. In this paper, we analyze how victimization during asylum seekers’ journeys affects their labor market integration in Germany by using survey data collected in the aftermath of the 2015 refugee crisis. Our data allow us to account for the exact timing and geography of migration, such that samples of physically victimized and nonvictimized refugees are balanced along a wide range of characteristics. We find that, compared to nonvictimized refugees, refugees who were physically victimized during their journey to Germany favor joining the labor force and taking up low-income employment rather than investing in host country human capital. To explain these findings, we explore a range of potential mechanisms and find suggestive evidence that experiencing physical victimization in vulnerable situations is not only associated with a decline in mental health but also with a “loss of future orientation” among physically victimized refugees, leading them to discount future payoffs more heavily.
We exploit exogenous variation in China’s export taxes to investigate the impact of Chinese foreign direct investment (FDI) in Ethiopia. Higher sector-specific export taxes in China lead to more Chinese FDI in Ethiopian districts specialized in those sectors and generate highly heterogeneous effects. Domestic firms competing with Chinese FDI reduce their sales, investment, inputs and prices, while firms in upstream and downstream sectors expand. We build a 20-year district panel of night lights and observe that Chinese FDI leads to no instantaneous impact on local growth, but significant and persistently positive effects after 6-12 years.
