During the early 1990s Germany received over half a million Yugoslavians fleeing war. By 2000, many of these refugees were repatriated. In their new paper, Dany Bahar and his co-authors exploit this episode to provide causal evidence on the role migrants play in contributing to productivity shifts in their home countries after their return, as explained by changes in comparative advantage.
They find that the elasticity of exports to return migration is between 0.1 to 0.24 in industries where migrants were employed during their stay in Germany. In order to deal with endogeneity issues they use historic exogenous rules of allocation of asylum seekers across different German states to construct an instrumental variable for the treatment. They also find their results to be externally valid when expanding the sample to all countries, and, furthermore, that they are mostly driven by workers in occupations intensive in characteristics more prevalent among managerial positions. These results point to knowledge diffusion as the main channel driving the link between migration and productivity shifts.
Indian agriculture remains vulnerable to the vagaries of weather, and the looming threat of climate change may expose this vulnerability further. Using district-level data on temperature, rainfall and crop production, Siddharth Hari’s paper first documents a long-term trend of rising temperatures, declining average precipitation and increase in extreme precipitation events. One key finding is that the impact of temperature and rainfall are felt only in the extreme: when temperatures are much higher, rainfall is significantly lower, and the number of “dry days” greater is than normal. He also finds that these impacts are significantly more adverse in unirrigated areas (and hence rainfed crops) compared to irrigated areas. Can policy makers react to the challenges of climate change and find ways to get “more crop for every drop?"
Estimating intergenerational mobility in developing countries is difficult because matched parent-child income records are rarely available and education is measured very coarsely. In particular, there are no established methods for comparing educational mobility for subsamples of the population when the education distribution is changing over time.
In their recent paper, Sam Asher and coauthors present new methods and new administrative data to overcome this gap, and study intergenerational mobility across groups and across space in India. They find that the intergenerational mobility for the population as a whole has remained constant since liberalization, but cross-group changes have been substantial. Rising mobility among historically marginalized "Scheduled Castes" is almost exactly offset by declining intergenerational mobility among Muslims, a comparably sized group that has few constitutional protections. These findings contest the conventional wisdom that marginalized groups in India have been catching up on average. The paper also explores heterogeneity across space, generating the first high-resolution geographic measures of intergenerational mobility across India, with results across 5600 rural subdistricts and 2300 cities and towns.
AidEx is a two day event, which encompasses a conference, exhibition, meeting areas, awards and workshops. Its fundamental aim is to engage the sector at every level and provide a forum for aid & development professionals to meet, source, supply and learn. AidEx was created to help the international aid and development community engage the private sector in a neutral setting, drive innovation and support the ever-growing need for emergency aid and development programmes.
