The Association Between Urbanisation and Household Food Security in Nigeria
A growing number of studies have shown that urbanisation is commonly associated with a change in dietary or consumption patterns towards more expensive and exotic foods. Previous attempts to investigate the implications of urbanisation on household food security have commonly employed dichotomous or binary indicators of urbanisation. Unlike previous studies, we employ satellite-based night-time light intensity data from the US Air Force Defense M…
The Long-Term Effects of Civil Conflict on Psychological Well-being
A growing literature shows that exposure to civil conflict could have long-term effects on psychological well-being in adulthood. This paper examines the long-term effects of exposure to the Nigerian civil war on the psychological well-being of heads of household using a difference-in-differences approach. We find that exposure to the civil war is associated with an increase in depressive score or symptoms in later life. We also find gender and l…
Women’s Inheritance Rights and Child Health Outcomes in Kenya
In recent years, many developing countries implemented inheritance rights reforms, aimed at abolishing any forms of gender discrimination in the arena of property rights. A few studies examine the interrelationship between inheritance rights reform and qualitative indicators of women’s well-being in terms of bargaining power at the household level, exposure to domestic violence, health outcomes and participation in labour markets. However, quanti…
Exploring how mobile money adoption affects nutrition and household food security
This paper explores how using mobile money services affects food security and nutritional status of households in Tanzania. This study uses data obtained from three waves of the Tanzanian National Panel Surveys and the instrumental variable (IV) approach. The evidence from this paper shows that using mobile money services resulted in household's enhanced nutritional and food security status. Households' receipt of remittances is the main pathway …
Long-Term Effects of Childhood Exposure to War on Domestic Violence
This paper highlights the scarring effects of early life exposure to civil war, by examining the impact of exposure to conflict in childhood on the incidence of domestic violence in adulthood among married women. To estimate these effects, we use a difference-in-differences model which exploits variation in exposure to Nigeria’s 30-month-long civil war by year of birth and ethnicity. Our results, based on the 2008 Nigerian Demographic Health Surv…
Mobile money, child labour and school enrolment
This paper analyses the impact of household adoption of mobile money services on child labour and schooling in Tanzania. The paper uses data drawn from the Tanzania National Panel Surveys (TNPS), for the survey periods as follows: 2008/09, 2010/11, 2012/13, and 2014/15. The TNPS are national representative surveys conducted by the National Bureau of Statistics of Tanzania in collaboration with the World Bank Living Standards Measurement Study-Int…
Impact of Intergovernmental Transfers on Household Multidimensional Well-Being
Do intergovernmental transfers affect the multidimensional well-being of households? This paper investigates the relationship between intergovernmental transfers and household multidimensional well-being, using the revenue allocation by the federal government to sub-national or state governments in Nigeria. We follow Alkire & Foster to compute a multidimensional poverty index (MPI), which is the weighted sum of three broad dimensions of povertyhe…
Reforming of Women’s Litigant Rights and Child Wellbeing: Evidence from Nigeria
Does a legal reform with patriarchal interpretations of the religious law codes affect the wellbeing of the children? In this study, we show that reforming the legal system by adopting a religious law, with high enforcement in some Nigerian states, affects a woman's bargaining power and utility outside marriage, which could adversely affect a child's wellbeing. We find empirical support for this framework by using a difference-in-differences desi…

The association between terrorist attacks and mental health: Evidence from Nigeria
This study examines the relationship between the Boko Haram conflict in Northeast Nigeria and the mental health of heads of households. The information on depressive symptoms (as a proxy for mental health) of household heads was collected using the Centre of Epidemiological Studies Short Depression Scale (CESD-10). The information on household coordinates provided in the 2015 wave of the Nigerian General Household Survey (GHS) was used to measure…
Women’s Inheritance Rights and Child Health Outcomes in India
Does a legal change in women’s inheritance rights have long-term effects on child health outcomes? This paper examines the effect of an improvement in women’s inheritance rights on child nutritional health outcomes in India using a difference-in-differences estimation approach. We use the staggered implementation of the Hindu Succession (Amendment) Act, 2005 to investigate the impact of the reform on anthropometric indictors of child health: bein…
The impact of timing of in utero drought shocks on birth outcomes in rural households: Evidence from Sierra Leone
This paper investigates the impact of timeline-bound fetal exposure to drought shocks on birth outcomes in rural Sierra Leone. We link repeated cross-section birth record data across 11 years from the Sierra Leone Demographic and Health Surveys to district-level geolocation precipitation data from the University of Delaware weather repository. The methodology uses spatial distribution of precipitation across districts to identify the impacts of e…
Coping with negative shocks and the role of the farm input subsidy programme in rural Malawi
This study uses household panel data from Malawi's 2010/11 and 2012/13 Integrated Household Panel Survey to investigate the mitigating role of its Farm Input Subsidy Programme (FISP) against the deleterious impacts of negative rainfall shock on households’ welfare in rural Malawi. The study finds that the FISP has a cushioning role on the negative impact of rainfall shocks. The use of a farm input subsidy scheme enables rural households to substa…
The Long-term Effects of Violent Conflict on Women’s Intra-Household Decision-Making Power
Does exposure to civil war during childhood affect women’s later-life intra-household decision-making power? This paper examines the long-term effects of early-life exposure to the Nigerian Civil War on women’s decision-making power within the household, using data from the 2008 Nigerian Demographic and Health Survey. To identify the effects, we adopt a difference-in-differences approach which exploits variation in exposure to the civil war by ye…
The Mitigating Impact of Land Tenure Security on Drought-Induced Food Insecurity: Evidence from Rural Malawi
This paper explores household variation in land tenure security and drought shocks across villages to investigate the extent to which land tenure systems matter in households’ capacity to cope with adverse impacts of weather shocks for agricultural dependent households in rural Malawi. Our findings reveal that land tenure security cushions the effects of drought regimes on food security. Further, we establish access to credit facilities for farm …
The impact of financial inclusion on mental health
This paper examines the impact of financial inclusion on the mental health of heads of household in Nigeria. The study employed data from the 2015/2016 Nigerian General Household Survey (GHS), matched with georeferenced data concerning financial services obtained from the Insight2Impact (i2i) GIS interface. The results indicate that financial inclusion has a strong positive impact on mental health. The study used a robust instrumental variable me…
Parental Disability and Children's Educational Outcomes: Evidence from Tanzania
This paper examines the relationship between parental disability and children's educational outcomes in Tanzania. This paper uses data from the 2010–2011 and 2014–2015 waves of the Tanzania National Panel Survey (TNPS) and a fixed effects estimation approach. The findings of this paper show that parental disability is associated with children being less likely to enrol in school and pass examinations. Also, we find a negative association between …
Impact of Shocks on Labour and Schooling Outcomes and the Role of Public Work Programmes in Rural India
The effectiveness of the National Rural Employment Guarantee Scheme (NREGS) on rural labour market dynamics in India has been widely debated in the literature. However, the impact of the NREGS on non-agricultural labour market and children schooling outcomes in reference to exogenous rainfall shock is unclear from the existing literature. This paper exploits the Indian National Sample Survey and rainfall measures from the precipitation archive of…
Parental income, child labour, and human capital accumulation: Evidence from trade liberalisation in India
This article examines whether parental income affects decisions on children’s human capital investment and labour market participation. India’s sudden and unanticipated trade liberalisation was a national policy that created an exogenous variation in industry-specific tariff rates over time. The policy consequently led to variation in workers’ earnings according to their industrial affiliations. The disparity in earnings across industries provide…
Gender and locational dimensions of shocks on household welfare: Empirical evidence from Nigeria
Many households in developing countries are exposed to numerous adverse events. The absence of a complete market for insurance and imperfect risk-sharing among households can lead to a significant effect on household welfare from shocks. This article examines the heterogeneous effects of income shocks on household welfare using two waves of the Nigerian General Household Survey Panel datasets from 2010/11 and 2012/13. The study adopted the househ…
