Gender,Weather Shocks and Welfare: Evidence from Malawi

This paper explores the gender-differentiated effects of weather shocks on households’ welfare in Malawi using panel data aligned with climatic records. Results show that temperature shocks severely affect household welfare, reducing consumption, food consumption and daily caloric intake. The negative welfare effects are more severe for households where land is solely managed by women, a finding that sheds light on the gender-unequal impact of temperature shocks. Our evidence also suggests that women’s vulnerability to temperature shocks is linked to women’s land tenure security, as temperature shocks significantly impact women’s welfare only in patrilineal districts, where statistics show that investment in agricultural technologies is lower.     

Weather Shocks and Spatial Market Efficiency: Evidence from Mozambique

The aim of this paper is to study the association between weather shocks (droughts and floods) and agricultural market performance in Mozambique. To do so, we employ a dyadic regression analysis on monthly maize prices, transport costs, and spatial identification of markets as well as droughts and flooded areas. Our estimates show that, while a drought reduces price differences between markets, price dispersion increases during flood periods, an effect that is mainly driven by increases in transport costs. Finally, floods are found to affect price differences more if markets are closer to each other and if the road infrastructure quality is poor. An important implication of our results is that markets show some degree of efficiency during supply shock periods in Mozambique. However, spatial market integration continues to be insufficient, probably due to high transfer costs.     

Cash Transfers Enable Households to Cope with Agricultural Production and Price Shocks: Evidence from Zambia

Climate change is projected to dramatically disrupt rainfall patterns and agricultural yields in sub-Saharan Africa. These shocks to food production can mire farming households in poverty traps. This study investigates whether unconditional cash transfers can help households cope with agricultural production and price shocks. We find that cash empowers poor, rural households facing these negative shocks to employ coping strategies typically used by the non-poor and enables them to substantially increase their food consumption and overall food security. Extending relatively small cash payments unconditionally to the rural poor is a powerful policy option for fostering climate-resilient development.     

Livestock Production,Rural Poverty,and Perceived Shocks: Evidence from Panel Data for Vietnam

This paper assesses the contribution of livestock to reducing rural poverty and examines the determinants of livestock assets with panel data from Vietnam. The findings show that livestock production contributes to reducing poverty and livestock assets are influenced by the number of shocks that households faced during the last three years, access to credits, farmland size, education of household head, irrigation system, and access to the national electricity. We suggest that empowering rural households to better cope with shocks contributes to developing livestock and consequently to reducing rural poverty.     

Impacts of Migration on Household Production Choices: Evidence from China

Abstract

The great migration from Chinese farms to cities during the past several decades ranks among the most economically consequential of modern population movements. We use a national sample of rice-producing Chinese households to examine the effects of that migration on agricultural production. Our assessment involves evaluating four alternative theories of labour market equilibrium in the framework of an expanded agricultural household model. Migration’s farm production impacts appear to be slight, not on account of farm labour market perfections or remittance-financed technological improvements, but by substituting a reduction in leisure and other low-return activities for lost labour.     

Child Schooling,Child Health,and Rainfall Shocks: Evidence from Rural Vietnam

Abstract

We study the effect of rainfall shocks on child schooling outcomes and on standardised height for age (a measure of child health) in rural Vietnam. We find that adverse rainfall shocks during pregnancy adversely affect children’s school entry delay and progress through school. Adverse rainfall shocks in the third year of life adversely affect both schooling and child health. These effects differ by region, as a result of constraints that reflect regional economic heterogeneity. We predict that policies that help rural families smooth income shocks will result in increases in human capital and in substantial cumulative returns over a worker’s working life.     

Agricultural Production and the Nutritional Status of Family Members in Tanzania

Abstract

The paper studies the effect of crop output value and livestock ownership on the nutrition of children, adolescents and adults in agricultural households. Using anthropometric data to measure nutritional status, this paper finds that both crop values and large livestock ownership have positive and significant effects on the nutrition of children under age 10. The effects persist after controlling for household socioeconomic status. Higher crop values and ownership of livestock are linked to better long-term indicators of nutrition (height-for-age) among the youngest children and better short-term indicators (BMI-for-age and weight-for-age) among older children. The effects also vary between boys and girls.     

Credit Availability and Internal Migration: Evidence from Thailand

This study investigates the relationship between borrowing and internal migration. Exploiting the micro-finance scheme Village Fund in Thailand, it investigates the short- and medium-term effects of borrowing since the policy’s introduction. Employing an instrumental variables approach, borrowing is instrumented using the inverse number of households per village at the beginning of the policy to capture potential credit availability. The findings suggest that internal migration in Thailand is not credit constrained and its interaction with credit is time-related. Borrowing reduces internal migration in the medium-term, but is found not to affect migration when the policy is first introduced.     

The Role of Empowerment in Agricultural Production: Evidence from Rural Households in Niger

We use new household and individual level WEAI data from the Tahoua region of Niger and estimate a variable coefficient Cobb-Douglas production function in which traditional inputs interact with two human capital variables – empowerment and formal education. Our estimation results reveal that human capital matters for productivity. So much so that it can be considered as technology-changing, significantly affecting a household’s production technology by enhancing returns to equipment. In fact, differentiating households by their status as dual or primary with only an adult female or male reveals that the productivity elasticity of empowerment is large for dual households in which women are the least empowered. Enhancing the empowerment of women in this group of households, by increasing their leadership skills or tenure security, would yield important productivity gains.     

Remittances and Chain Migration: Longitudinal Evidence from Bosnia and Herzegovina

Abstract

Most of the literature on remittances focuses on their implications for the welfare of family members in the country of origin and disregards their role as facilitator of chain migration. We address this issue with the use of longitudinal data from Bosnia and Herzegovina, one of the primary exporters of migrants and recipients of remittances in the world. We find that remittances have a significant positive impact on the migration prospects of their recipients. Better-endowed people are most likely to migrate, which highlights a potential negative implication of migration and remittances.     

Modernisation and Time Preferences in Tanzania: Evidence from a Large-Scale Elicitation Exercise

Assumptions about individual time preferences are important for explanations of poverty and development. Data from a large-scale elicitation exercise in Tanzania show significantly higher levels of impatience in urban areas than in rural areas. This result remains robust to adding controls for socio-economic differences between rural and urban areas, which possibly correlate with time preferences. We attribute this to differences in ‘modernisation’ between urban and rural areas, with modernisation leading to increased impatience. This is corroborated by the observed positive correlation between impatience and education; the latter being an important vehicle of modernisation for traditional societies in Tanzania.     

Estimating the Effects of Climate Shocks on Collective Violence: ARDL Evidence from India

This paper examines the causal relationship between climate shocks and collective violence in India using annual data over the period 1954–2006. We use the ARDL bounds testing approach to deal with problems of autocorrelation and non-stationarity of key variables. Rather than rainfall, we find that it is maximum temperature that has long and short run effects on collective violence, with unidirectional causality from temperature shocks to riots. A one standard deviation increase in maximum temperature over the long run average increases the number of riots by 55 per cent. Return to long run equilibrium after a temperature shock takes approximately 15 years. The insignificance of rainfall holds whether we consider rainfall levels or rainfall growth. Given the absence of long run relationships between income levels /growth and riots, it is unlikely that the income channel is the one through which climate affects riots in India. Instead, the evidence suggests a psychological channel through which temperature affects riots in India, with hotter temperatures being associated with increased levels of aggression.     

Education,Employment and Earnings of Secondary School and University Leavers in Tanzania: Evidence from a Tracer Study

This study uses a tracer survey of secondary school completers in Tanzania to analyse the impact of educational qualifications on labour market earnings. We show that the rates of return to the highest educational qualifications for wage employees are not negligible and, at the margin, provide an investment incentive. However, we find little evidence of human capital effects in the earnings determination process for the self-employment sector. Introducing controls for father's educational background and a set of school fixed effects designed to proxy for school quality and potential labour market network effects reduces the estimated rates of return to educational qualifications. A comparison of our results with the available evidence from other countries in the region suggest that, despite an extremely small secondary and university education system, the private rates of return to education in the Tanzanian wage employment sector are comparatively low.     

Junior Farmer Field Schools,Agricultural Knowledge and Spillover Effects: Quasi-Experimental Evidence from Northern Uganda

We analyse the impact of a junior farmer field school project in Northern Uganda on students’ agricultural knowledge and practices. We also test for the presence of intergenerational learning spillover within households. We use differences-in-differences estimators with ex-ante matching and find evidence that the programme had positive effects on students’ agricultural knowledge and adoption of good practices. The project also produced spillover effects in terms of improvements of household agricultural knowledge and food security. Overall, our results point to the importance of adapting the basic principles of farmer field schools to children.     

How Does Information About Elite Tax Evasion Affect Political Participation: Experimental Evidence from Tanzania

We present results of a randomised field experiment where voters in Tanzania were given information about elite use of tax havens. Information provided in a neutral form had no effect, while information phrased in more morally charged terms led to a reduction in voting intentions. Rather than increase the perceived importance of voting, charged information tends to undermine confidence in political institutions and the social contract. The effects are particularly pronounced among the less well off, indicating that increased transparency in the absence of perceived agency may not improve political participation.     

Policy Shocks: On the Legal Auspices of Latin American Migration to the United States

In this paper, I compare the transition into legal permanent residence (LPR) of Mexicans, Dominicans, and Nicaraguans. Dominicans had the highest likelihood of obtaining residence, mostly sponsored by parents and spouses. Mexicans had the lowest LPR transition rates and presented sharp gender differentials in modes: women mostly legalized through husbands while men were sponsored through IRCA, parents. Nicaraguans stood in-between, presenting few gender differences in rates and modes of transition and a heavy dependence on asylum and special provisions such as IRCA and NACARA. I argue these patterns stem from the interplay of conditions favoring the emigration of and the specific immigration policy context faced by migrant pioneers; the influence of social networks in reproducing the legal character of flows; and differences in the actual use of kinship ties as sponsors. I discuss the implications of these trends on the observed gendered patterns of migration from Latin America.     

Uninsured Health Shocks and Agricultural Productivity among Rural Households: The Mitigating Role of Micro-credit

This article investigates how health shocks affect farm productivity in the presence of microcredit. It is expected that microcredit increases agricultural productivity by enhancing allocative and technical efficiency and by overcoming financial constraints that reduce purchase of inputs. However, microcredit will have competing uses in the event of uninsured health shocks to the household. Using an endogenous switching regression model and after accounting for self-selection, the results reveal that microcredit has a significant mitigating effect on farm productivity losses. Thus, microcredit generates a double dividend among smallholders serving as insurance against health shocks in rural areas and improving agricultural productivity.     

Agricultural Production,Dietary Diversity and Climate Variability

Abstract

Nonseparable household modelsoutline the interlinkage between agricultural production and household consumption, yet empirical extensions to investigate the effect of production on dietary diversity and diet composition are limited. While a significant literature has investigated the calorie-income elasticity abstracting from production, this paper provides an empirical application of the nonseparable household model linking the effect of exogenous variation in planting season production decisions via climate variability on household dietary diversity. Using degree days, rainfall and agricultural capital stocks as instruments, the effect of production on household dietary diversity at harvest is estimated. The empirical specifications estimate production effects on dietary diversity using both agricultural revenue and crop production diversity. Significant effects of both agricultural revenue and crop production diversity on dietary diversity are estimated. The dietary diversity-production elasticities imply that a 10 per cent increase in agricultural revenue or crop diversity result in a 1.8 per cent or 2.4 per cent increase in dietary diversity respectively. These results illustrate that agricultural income growth or increased crop diversity may not be sufficient to ensure improved dietary diversity. Increases in agricultural revenue do change diet composition. Estimates of the effect of agricultural income on share of calories by food groups indicate relatively large changes in diet composition. On average, a 10 per cent increase in agricultural revenue makes households 7.2 per cent more likely to consume vegetables, 3.5 per cent more likely to consume fish, and increases the share of tubers consumed by 5.2 per cent.     

Private Sector Incentives and the Diffusion of Agricultural Technology: Evidence from Developing Countries

The role of intellectual property rights (IPRs) has been extensively debated in the literature on technology transfers and agricultural productivity growth in developing countries. However, few studies offer cross-country evidence on how IPRs affect yield growth by incentivising private sector investment in cultivar improvement. We address this knowledge gap by testing technology diffusion patterns for six major crops using a unique dataset for the period 1961–2010 and an Arellano–Bond linear dynamic panel-data estimation approach. Findings indicate that biological and legal forms of IPRs promote yield gap convergence between developed and developing countries, although effects vary by crop.
