CIVIL WAR EXPOSURE AND VIOLENCE

In recent years scholars have begun to focus on the consequences of individuals' exposure to civil war, including its severe health and psychological consequences. Our innovation is to move beyond the survey methodology that is widespread in this literature to analyze the actual behavior of individuals with varying degrees of exposure to civil war in a common institutional setting. We exploit the presence of thousands of international soccer (football) players with different exposures to civil conflict in the European professional leagues, and find a strong relationship between the extent of civil conflict in a player's home country and his propensity to behave violently on the soccer field, as measured by yellow and red cards. This link is robust to region fixed effects, country characteristics (e.g. rule of law, per capita income), player characteristics (e.g. age, field position, quality), outliers, and team fixed effects. Reinforcing our claim that we isolate the effect of civil war exposure rather than simple rule breaking or something else entirely, there is no meaningful correlation between our measure of exposure to civil war and soccer performance measures not closely related to violent conduct. The result is also robust to controlling for civil wars before a player's birth, suggesting that it is not driven by factors from the distant historical past.     

Fatal fluctuations? Cyclicality in infant mortality in India

This paper investigates the impact of aggregate income shocks on infant mortality in India and investigates likely mechanisms. A recent OECD-dominated literature reports the provocative finding that mortality at most ages is pro-cyclical. Similar analyses for poorer countries are scarce, and both income risk and mortality risk are greater in poor countries. This paper uses data and methods designed to avoid some of the specification problems in previous studies and it explores mechanisms and extensions that have not been previously considered. It uses individual data on infant mortality for about 150,000 children born in 1970-1997, merged by cohort and state of birth with a state panel containing information on aggregate income. Identification rests upon comparing the effects of annual deviations in income from trend on the mortality risks of children born at different times to the same mother, conditional upon a number of state-time varying covariates including rainshocks and state social expenditure. Rural infant mortality is counter-cyclical, the elasticity being about − 0.33. This is despite the finding that relatively high-risk women avert birth or suffer fetal loss in recessions. It seems in part related to recessions stimulating distress labor amongst mothers, in contrast to the case in richer countries, where they discourage labor market participation. Health-care seeking declines in recessions, and this appears to be related to the opportunity cost of maternal time. Disaggregation reveals that the average results are driven by rural households in which the mother is uneducated or had her first birth in teenage, and that it is only girls that are at risk; boys are protected from income shocks. Exposure to poor conditions in the fetal and neonatal period appears to have a larger effect on infant mortality than similar exposure in the postneonatal period.     

ACTIVITY CHOICES OF INTERNALLY DISPLACED PERSONS AND RETURNEES: QUANTITATIVE SURVEY EVIDENCE FROM POST‐WAR NORTHERN UGANDA

We investigate post‐war economic activity choices of displaced and just‐returned individuals. In particular, the effect of living in an internally displaced persons camp on the choice of economic activities is analysed. Because individuals relocating away from camps may be different from those staying in them, a recursive bivariate probit procedure is used to control for selection on unobservables. The empirical procedure also relies on merging survey data with the micro‐level dataset on conflict events. This allows us to incorporate conflict in the framework, but also to use a bivariate probit procedure to control for endogeneity (selection of households out of camps). This work contributes to literature on household labour allocation and economics of conflict. Results show that residing in a camp has varied effects on the choice of economic activities. Individuals in camps may be more inclined than those who choose to return home, to engage in certain economic activities. One of the key lessons that could be drawn from this paper is that internally displaced persons may possess important livelihood skills that post‐conflict development interventions need to take advantage of, in order to fast‐track recovery.     

The long-term effects of civil conflicts on education,earnings, and fertility: Evidence from Cambodia

This paper examines the long-term effects of exposure to civil war and genocide on the educational attainment, earnings, and fertility of individuals in Cambodia. Given the well-documented causal links between schooling and labor productivity, it is surprising that past studies show that civil conflicts reduce educational attainment, but generally not earnings of individuals. Using variation in the degree of Cambodians’ exposure to civil conflicts during primary school age, we find that disruption to primary education during civil conflicts decreases educational attainment and earnings, increases fertility, and has negligible effects on health of individuals several decades later. Our findings suggest that the effect of conflict on schooling disruption has adverse consequences on long-term labor productivity and economic development.     

Growing up in a civil war and political participation: Evidence from Guatemala*

Guatemala experienced a 36-year-long civil war from 1960 to 1996. I use this event to understand whether growing up in an area of political violence has any impact on future political participation. I combine data from the distribution of the number of human rights violations during Guatemala's civil war with nationally representative data on political participation from the 2001 Living Standard Measurement Survey. Results suggest that exposure to conflict during youth affects political participation in adulthood. Exposure to conflict has a small negative association with formal political engagement and it has no effect on community participation. The results also indicate a negative relationship between growing up in an area of political violence and trust in the judicial system as adults.     

The intergenerational transmission of historical conflicts: An application to China’s trade

We study the legacy effect and transmission mechanisms of historical conflicts on contemporary trade. Using new data on the regional dispersion of civilian deaths due to massacres in the Sino-Japanese war (1931–1945), we find that local conflict intensity predicts international trade patterns of Chinese corporations three generations later. We further explore the transmission mechanism of collective war memory. Conflict intensity correlates with measures of anti-Japanese sentiments inferred from survey data and it appears to be transmitted both through war dramas in the mass media as well as official commemorations. We also find evidence that the trade-inhibiting effect increases with the time exposed to collective war memory.

Crop burning and forest fires: Long-term effect on adolescent height in India

This paper examines the effect of biomass burning on adolescent health in India. The biomass burning problem is quite acute especially in North India, with some states experiencing forest fires and few states actively engaging in crop burning practice. We combine remote sensing data on biomass burning events with a pan-India survey on teenage girls (TAG survey). We exploit regional and temporal variation in our data to establish the link between occurrence of extremely high levels of biomass burning during early life and adolescent height for girls in India. Our results indicate that exposure to extremely high level of biomass burning during prenatal and postnatal period is associated with lower height (by 0.7 percent or 1.07 cm) later in life. Girls from North India are found to be especially vulnerable to the harmful effects of exposure to biomass burning.     

Nepal's civil war and the changing sources of income: The role of sectoral shifts and remittances in mitigation and recovery

Given the increased worldwide unrest and a large number of displaced individuals, understanding the economic impacts of civil war has been the subject of growing attention by academics and policymakers. The 10‐year civil war in Nepal from 1996 to 2006 provides an opportunity to assess the impact of civil unrest on income sources and remittance patterns. In this study, we examine the changes in household income generating processes over the period of the Nepali civilwar. Using survey data from the Nepal Living Standards Survey (NLSS) in 1995/1996 and 2010/2011, we observe household income and remittance patterns before and after the civil war. Specifically, we employ a difference‐in‐difference estimator that focuses on the heterogeneity in civil unrest within Nepal to examine how the civil war impacted the sources of household income. Within the context of a slower growth rate of income after the revolution for those in the hardest hit districts, we find that there was also a change in the composition of income sources. In particular, our results suggest that there was a shift from a reliance on wages in the nonagricultural sector to wages in the agricultural sector; that there was a shift from external remittances to internal remittances; and finally that home production—the market value of items produced and consumed within the household—may be taking the place of income in regions hit by unrest. “People living in zones of war are maimed, killed, and see their property destroyed. They may be displaced or prevented from attending school or earning a living. To the extent that these costs are borne unequally across groups, the conflict could intensify economic inequality as well as poverty. The destruction (and deferred accumulation) of both human and physical capital also hinder macroeconomic performance, combining with any effects of war on institutions and technology to impact national income growth. Understanding the economic legacies of conflict is important to the design of post‐conflict recovery” (Blattman & Miguel, 2010).     

The effect of armed conflict on accumulation of schooling: Results from Tajikistan

This paper uses differences in regional and temporal exposure to the 1992-1998 armed conflict in Tajikistan to study the effect of violent conflict on schooling outcomes. Data on the past damage to a household's residences from the 1999 Tajik Living Standards Survey is used as well as data on the events during the conflict within a conceptual framework that controls for important individual, household and community characteristics. Girls who were of school age during the conflict and lived in affected regions were less likely to complete their mandatory schooling than girls of the same age who lived in the regions relatively unaffected by conflict. The results also indicate that exposure to violent conflict had a large and statistically significant negative effect on the enrollment of girls. No effect of regional and household conflict exposure on education of boys was found. The results are robust to community and household fixed effects, selection into violence and migration.     

Trade flows in a spatial oligopoly: gravity fits well,but what does it explain?

Abstract .  Large distance and border effects on trade flows in some industries may result from the collusive division of geographic markets. In the Brazilian cement industry, traditional gravity equations fit the data well, yet limited regional flows are due to firms' strategic behaviour. Thanks to a unique institutional setting and an unusually rich data set, I directly control for trade costs, which – despite their importance – cannot account for the observed segmentation of local markets at current prices. The paper highlights how collusive behaviour can magnify the effects of distance, as firms use geography to coordinate on higher prices and less cross-hauling.     

The human capital consequences of civil war: Evidence from Guatemala

We combine data from the 2002 National Population Census and the distribution of the number of human rights violations and victims across 22 departments to examine how Guatemala's 36-year-long civil war affected human capital accumulation. The year of birth and the department of birth jointly determine an individual's exposure during school age to three different periods of the civil war, namely the initial period (1960-1978), the worst period (1979-1984), and the final period (1985-1996). We find a strong negative impact of the civil war on the education of the two most disadvantaged groups, namely rural Mayan males and females. Among rural Mayan males, those who were school age during the three periods of the civil war in departments where more human rights violations were committed completed 0.27, 0.71, and 1.09 years less of schooling respectively whereas rural Mayan females exposed to the three periods of the war completed 0.12, 0.47, and 1.17 years less of schooling respectively. Given an average of 4.66 and 3.83 years of schooling for males and females, these represent declines of 6, 15, and 23% for males and 3, 12, and 30% for females. Our results are robust to the inclusion of indicators for department of residence, year of birth, and controls for different trends in education and human development in war-affected and peaceful departments of Guatemala and suggest that the country's civil war may have deepened gender, regional, sectoral, and ethnic disparities in schooling.     

Something in the water: contaminated drinking water and infant health

This paper provides estimates of the effects of in utero exposure to contaminated drinking water on fetal health. To do this, we examine the universe of birth records and drinking water testing results for the state of New Jersey from 1997 to 2007. Our data enable us to compare outcomes across siblings who were potentially exposed to differing levels of harmful contaminants from drinking water while in utero. We find small effects of drinking water contamination on all children, but large and statistically significant effects on birth weight and gestation of infants born to less educated mothers. We also show that those mothers who were most affected by contamination were the least likely to move between births in response to contamination.     

Indian residential schools: Height and body mass post‐1930

We study the effects of Canadian Indian residential schooling on two anthropometric measures of health during childhood: adult height and body weight. We use repeated cross‐sectional data from the 1991 and 2001 Aboriginal Peoples Survey and leverage detailed historical data on school closures and location to make causal inferences. We find evidence that, on average, residential schooling increases adult height and the likelihood of a healthy adult body weight for those who attended. These effects are concentrated after the 1950s, when the schools were subject to tighter health regulations and students were selected to attend residential school based partly on their need for medical care that was otherwise unavailable. Residential schooling is only one policy in Canada that had an impact on the health of status First Nations peoples, so our results must be understood in the broader social context. Taken in context, our results suggest that health interventions in later childhood can have significant impacts on adult health. We also document significant increases in height and body weight for status peoples born after the 1960s, suggesting substantial changes in diet and living conditions during this period.     

Self‐rated Health Status of Japanese and Europeans in Later Life: Evidence from JSTAR and SHARE

Using panel data from two surveys in Japan and Europe, we examine the comparability of the self‐rated health of the middle‐aged and elderly across Japan and European countries and across the survey periods. We find that a person's own health is evaluated using different standards (thresholds) across the different countries and survey waves. When evaluated using common thresholds, the Japanese elderly are found to be healthier than their counterparts in the European countries. Reporting biases causing discrepancies between the changes in individuals' self‐rated health and their actual health over the survey waves are associated with education and country of residence.     

Violent conflict and online segregation: An analysis of social network communication across Ukraine's regions

Does the intensity of a social conflict affect political division? Traditionally, social cleavages are seen as the underlying cause of political conflicts. It is clear, however, that a violent conflict itself can shape partisan, social, and national identities. In this paper, we ask whether social conflicts unite or divide the society by studying the effects of Ukraine's military conflict with Russia on online social ties between Ukrainian provinces (oblasts). In order to do that, we collected original data on the cross-regional structure of politically relevant online communication among users of VKontakte social networking site. We analyze the panel of provinces spanning the most active phases of domestic protests and military conflict and isolate the effects of province-specific war casualties on the nature of inter-provincial online communication. The results show that war casualties entice strong emotional response in the corresponding provinces, but do not necessarily increase the level of social cohesion in inter-provincial online communication. We find that the intensity of military conflict entices online activism, but activates regional rather than nation-wide network connections. We also find that military conflict tends to polarize some regions of Ukraine, especially in the East. Our research brings attention to the underexplored areas in the study of civil conflict and political identities by documenting the ways the former may affect the latter.     

Effects of Economic Shocks on Children's Employment and Schooling in Brazil

This paper uses longitudinal employment survey data to analyze the impact of household economic shocks on the schooling and employment transitions of young people in metropolitan Brazil. The paper uses data on over 100,000 children ages 10-16 from Brazil's Monthly Employment Survey (PME) from 1982 to 1999. Taking advantage of the rotating panels in the PME, we compare households in which the male household head becomes unemployed during a four-month period with households in which the head is continuously employed. Probit regressions indicate that an unemployment shock significantly increases the probability that a child enters the labor force, drops out of school, and fails to advance in school. The effects can be large, implying increases of as much as 50% in the probability of entering employment for 16-year-old girls. In contrast, shocks occurring after the school year do not have significant effects, suggesting that these results are not due to unobserved characteristics of households that experience unemployment shocks. The results suggest that some households are not able to absorb short-run economic shocks, with negative consequences for children.     

Bilateral war in a multilateral world: carrots and sticks for conflict resolution

Abstract.  This paper constructs a three-country, specific-factor, trade-theoretic model in which two of the countries are in conflict and where war effort is determined endogenously in a Nash equilibrium. The third country does not take part in the war, but trades with the warring countries. In the framework, we examine, inter alia, how war and welfare are affected by globalization and by two instruments available to the third country – one carrot and one stick. Our overall conclusion is that the third parties do have the incentives for, and can play an effective role in, conflict resolution. JEL classification: F02, F11, H56, H77     

Make Trade Not War?

This paper analyses theoretically and empirically the relationship between military conflicts and trade. We show that the conventional wisdom that trade promotes peace is only partially true even in a model where trade is economically beneficial, military conflicts reduce trade, and leaders are rational. When war can occur because of the presence of asymmetric information, the probability of escalation is lower for countries that trade more bilaterally because of the opportunity cost associated with the loss of trade gains. However, countries more open to global trade have a higher probability of war because multilateral trade openness decreases bilateral dependence to any given country and the cost of a bilateral conflict. We test our predictions on a large data set of military conflicts on the 1950–2000 period. Using different strategies to solve the endogeneity issues, including instrumental variables, we find robust evidence for the contrasting effects of bilateral and multilateral trade openness. For proximate countries, we find that trade has had a surprisingly large effect on their probability of military conflict.     

Son Preference,Number of Children,Education and Occupational Choice in Rural Nepal

A unique family survey was conducted in Nepal to investigate the economic consequences of having a first‐born girl. Women have more children, but we find no causal effect of number of children on economic outcomes, but independently of the number of children there is a positive effect on boys’ education of having a first‐born sister, who presumably takes care of household work so the boys can focus on school. This indicates a stronger son preference in Nepal than that found in studies from neighboring countries.
