Poverty reduction in a refugee-hosting economy: A natural experiment

The role of migration in reducing poverty in developing countries has been investigated mainly from the perspective of migrants and their relatives. This paper exploits the time and spatial variations in the way households in the region of Kagera (Tanzania) traced between 1991 and 2004 have been affected by massive refugee inflows to assess how migration may affect poverty in the hosting communities. Large population inflows from Burundi and Rwanda have improved the welfare of the hosting population, particularly for the poor. Despite the process of structural transformation observed in the refugee-hosting economy, such pro-poor development is mainly explained by improved agricultural labor productivity and income diversification among the poor.Migration, Poverty, Refugees, Structural transformation,

The transmission of health across 7 generations in China, 1789-1906

We study the intergenerational transmission of health using linked registered data from China between 1789 and 1906. We first document the intergenerational correlations across 7 generations. We then identify intergenerational causal associations comparing children born from twin mothers or fathers. In particular, we find a strong and persistent intergenerational elasticity between mothers and children of about 0.52. The intergenerational association from fathers is much weaker and seems to be largely driven by genetic factors. The estimates remain relatively stable up to generation 5 and are robust to different checks. Overall, our results highlight the nurturing role of women in explaining the intergenerational transmission of health, stressing the key role played by women in affecting children's health outcomes in developing countries

In utero seasonal food insecurity and cognitive development: Evidence from Ethiopia

Food insecurity is pervasive and highly seasonal in Ethiopia. In this study, we investigate the effect of seasonal food insecurity on child development. Exploiting the Young Lives Ethiopia dataset, we study the impact of in utero exposure to seasonal food insecurity on cognitive development for children of age 8 up to 12. We find that at age 8 in utero exposure to food insecurity shocks negatively, although insignificantly, affects cognitive development. But, at age 12, such exposure significantly reduces cognitive development. In utero exposure to seasonal food insecurity translates into a loss of 0.52 standard deviations in maths achievements score. Exposure during the first and second trimesters of pregnancy are found to have stronger detrimental effects. We also find stronger effects for boys

The development push of refugees:evidence from Tanzania

We exploit a 1991–2010 Tanzanian household panel to assess the effects of the temporary refugee inflows originating from Burundi (1993) and Rwanda (1994). We find that the refugee presence has had a persistent and positive impact on the welfare of the local population. We investigate the possible channels of transmission, underscoring the importance of a decrease in transport costs as a key driver of this persistent change in welfare. We interpret these findings as the ability of a temporary shock to induce a persistent shift in the equilibrium through subsequent investments rather than a switch to a new equilibrium in a multiple-equilibrium setting

National or political cake?:the political economy of intergovernmental transfers in Nigeria

Analysing the effect of opportunistic fiscal transfers on the electoral fortune of incumbent politicians can be very difficult due to problems of endogeneity. In this paper, we use oil windfalls as an exogenous variation in the political discretion an incumbent government can exert in rule-based transfers. Exploiting within-state variation between 2007 and 2015 in Nigeria, an increase in VAT transfers induced by higher oil windfalls is found to improve the electoral fortune of an incumbent government. Our results question the role of rule-based transfers as an efficient institutional arrangement in resource-abundant countries

Weather shocks, maize yields and adaptation in rural China

Based on panel household data collected between 2004 and 2010, we assess the impact of weather shocks on maize yields in the two main producing regions in China, the Northern spring maize zone and the Yellow-Huai Valley summer maize zone. Temperature, drought, wet conditions, and precipitations have detrimental effects on maize yields in the two maize zones. Nonetheless, the magnitude of those effects appears to be low compared to other parts of the world. Adaptation seems to be key in the region where the largest impact is estimated. On the contrary, the lower impact found in the other region, the Yellow-Huai Valley summer maize zone, is low but likely to intensify

Local warming and violent conflict in North and South Sudan

Our article contributes to the emerging micro-level strand of the literature on the link between local variations in weather shocks and conflicts by focusing on a pixel-level analysis for North and South Sudan between 1997 and 2009. Temperature anomalies are found to strongly affect the risk of conflict, whereas the risk is expected to magnify in a range of 24–31% in the future under a median scenario. Our analysis also sheds light on the competition over natural resources, in particular water, as the main driver of such relationship in a region where pastoralism constitutes the dominant livelihood

Environmental migration and labor markets in Nepal

While an emerging literature cites weather shocks as migration determinants, scant evidence exists on how such migration affects the markets of receiving communities in developing countries. We address this knowledge gap by investigating the impact of weather-driven internal migration on labor markets in Nepal. An increase of 1 percentage point in net migration reduces wages in the formal sector by 5.7%. A similar change in migration augments unemployment by 1 percentage point. The unskilled bear greater consequences. Understanding entrepreneurial constraints and drivers of labor market exits will inform pathways to resilience

While an emerging literature cites weather shocks as migration determinants, scant evidence exists on how such migration impacts the markets of receiving communities in developing countries. We address this knowledge gap by investigating the impact of weather-driven internal migration on labor markets in Nepal. An increase of 1 percentage point in net migration reduces wages in the formal sector by 4.8 percentage points. The absence of wage effects in the informal sector is consistent with the exit of low-skilled native workers from the labor market. Understanding entrepreneurial constraints and drivers of labor market exits will inform pathways to resilience
