This paper theoretically analyzes and empirically investigates the importance of local interaction between individuals of different linguistic groups for the provision of public goods at the national level. Depending on whether local interaction mitigates or reinforces antagonism towards other groups, the micro-founded theory we develop predicts that a country's provision of public goods (i) decreases in its overall linguistic fractionalization, and (ii) either increases or decreases in how much individuals locally learn about other groups. After constructing a 5 km by 5 km geographic dataset on language use for 223 countries, we compute measures of overall fractionalization and local learning, and investigate their relation to public good provision at the country level. While overall fractionalization worsens outcomes, we find a positive causal relation between local learning and public goods. Local mixing therefore mitigates the negative impact of a country's overall linguistic fractionalization. An IV strategy shows that this result is not driven by the possible endogenous spatial distribution of language speakers within countries.
This paper contributes to a burgeoning literature that uses sub-national micro data to identify the causes of civil conflicts. In particular, we study the Maoist/Naxalite conflict in India by constructing a comprehensive district level database using conflict data from four different terrorism databases and combining it with socioeconomic and geography data from myriad sources. In addition to exploiting the within country regional heterogeneity, we use the micro structure of the data to construct group-level characteristics. Using data on 360 districts for 3 time periods, we find evidence on how land inequality and lower incomes are important for the Maoist conflict. Moreover, making use of the micro structure of the data we are able to ask whether exclusion of the low castes and tribes from the growth story of India is important. We find that while the income levels of the different ethnic groups are not important, the growth of incomes of Scheduled Tribes significantly decreases the intensity of the conflict. Finally, we show how historical property rights institutions from colonial times that go back centuries can affect present day conflict outcomes through their impact on economic outcomes, social relations and the political environment in the district.
We show that ethnic distances lead to worse child health outcomes by impeding access to health-related information. We combine individual level micro data from DHS surveys for fourteen sub-Saharan African countries, with a high-resolution dataset on the spatial distribution of ethnic groups at the 1 × 1 sq. km level constructed using an Iterative Proportional Fitting algorithm. We show that children whose mothers are linguistically more distant to their neighbours face higher mortality rates and are shorter in size. Linguistically distant mothers are also less likely to know about the oral rehydration product for treating children with diarrhoea.
We examine the role of FM radio in mitigating violent conflict. We collect original data on radio broadcasts encouraging defections during the Lord’s Resistance Army (LRA) insurgency. This constitutes the first quantitative evaluation of an active counterinsurgency policy that encourages defections through radio messages. Exploiting random topography-driven variation in radio coverage along with panel variation at the grid-cell level, we identify the causal effect of messaging on violence. Broadcasting defection messages increases defections and reduces fatalities, violence against civilians, and clashes with security forces. Income shocks have opposing effects on both the conflict and the effectiveness of messaging. (JEL D74, L82, O17)
provides economic analysis and policy advice with the aim of promoting sustainable and equitable development. The Institute began operations in 1985 in Helsinki, Finland, as the first research and training centre of the United Nations University. Today it is a unique blend of think tank, research institute, and UN agency-providing a range of services from policy advice to governments as well as freely available original research. The Institute is funded through income from an endowment fund with additional contributions to its work programme from Finland, Sweden, and the United Kingdom as well as earmarked contributions for specific projects from a variety of donors.
Millions of women continue to die during and soon after childbirth, even where the knowledge and resources to avoid this are available. We posit that raising the share of women in parliament can trigger action. Leveraging the timing of gender quota legislation across developing countries, we identify sharp sustained reductions of 8-10 percent in maternal mortality. Investigating mechanisms, we find that gender quotas lead to increases in percentage points of 5-8 in skilled birth attendance and 4-8 in prenatal care utilization, alongside a decline in fertility of 6-7 percent and an increase in the schooling of young women of about 0.5 years. The results are robust to numerous robustness checks. They suggest a new policy tool for tackling maternal mortality.
We show that large declines in maternal mortality can be achieved by raising women's political participation. We estimate that the recent wave of quotas for women in parliament in low income countries has resulted in a 9 to 12% decline in maternal mortality. Among mechanisms are that gender quotas lead to an 8 to 10% increase in skilled birth attendance, a 6 to 12% increase in prenatal care utilization, and a 4 to 11% decrease in birth rates.
