Ted's main research focus is African economic development, including work on the economic causes and consequences of violence; the impact of ethnic divisions on local collective action; interactions between health, education, environment, and productivity for the poor; and methods for transparent social science research. He has conducted field work in Kenya, Sierra Leone, Tanzania, and India. Many of the datasets used in his research are posted online, either on the relevant article page (on this website) or on Dataverse.
This study estimates long-run impacts of a child health investment, exploiting community-wide experimental variation in school-based deworming. The program increased labor supply among men and education among women, with accompanying shifts in labor market specialization. Ten years after deworming treatment, men who were eligible as boys stay enrolled for more years of primary school, work 17% more hours each week, spend more time in non-agricultural self-employment, are more likely to hold manufacturing jobs, and miss one fewer meal per week. Women who were in treatment schools as girls are approximately one quarter more likely to have attended secondary school, halving the gender gap. They reallocate time from traditional agriculture into cash crops and non-agricultural self-employment. We estimate a conservative annualized financial internal rate of return to deworming of 32%, and show that mass deworming may generate more in future government revenue than it costs in subsidies.

Understanding the possible pitfalls of survey data is critical for empirical research. Among other things, poor data quality can lead to biased regression estimates, potentially resulting in incorrect interpretations that mislead researchers and policymakers alike. Common data problems include difficulties in tracking respondents and high survey attrition, enumerator error and bias, and respondent reporting error. This paper describes and analyzes these issues in Round 1 of the Kenyan Life Panel Survey (KLPS-1), collected in 2003-2005. The KLPS-1 is an innovative longitudinal dataset documenting a wide range of outcomes for Kenyan youths who had originally attended schools participating in a deworming treatment program starting in 1998. The careful design of this survey allows for examination of an array of data quality issues.

We study cultural norms and legal enforcement in controlling corruption by analyzing the parking behavior of United Nations officials in Manhattan. Until 2002, diplomatic immunity protected UN diplomats from parking enforcement actions, so diplomats' actions were constrained by cultural norms alone. We find a strong effect of corruption norms: diplomats from high-corruption countries (on the basis of existing survey-based indices) accumulated significantly more unpaid parking violations. In 2002, enforcement authorities acquired the right to confiscate diplomatic license plates of violators. Unpaid violations dropped sharply in response. Cultural norms and (particularly in this context) legal enforcement are both important determinants of corruption.

This chapter is devoted to discussions of how assessments of early childhood development (ECD) interventions in developing countries can be improved and extended. There are estimates that ECD problems are widespread in developing countries, increasing evidence that what happens in early childhood affects significantly options and productivities over the life cycles but very little systematic evidence to support that the impacts of these ECD programs are large or, more importantly, that the benefit-to-cost ratios of ECD interventions are high – particularly in light of the heterogeneous market, policy, and cultural contexts across developing countries that may limit the transferability of inferences from one context to another. Therefore the returns are potentially great not only for those who already are persuaded that more resources should be devoted to EDC interventions in developing countries in order that they can make their case more persuasively but also for those who are concerned more broadly about prioritizing resource allocations across what might seem to be a number of strong but difficult-to-compare alternatives ranging from other human resource investments to physical infrastructure investments to...

AIDS deaths could have a major impact on economic development by affecting the human capital accumulation of the next generation. We estimate the impact of parent death on primary school participation using an unusual five-year panel data set of over 20,000 Kenyan children. There is a substantial decrease in school participation following a parent death and a smaller drop before the death (presumably due to pre-death morbidity). Estimated impacts are smaller in specifications without individual fixed effects, suggesting that estimates based on cross-sectional data are biased toward zero. Effects are largest for children whose mothers died and, in a novel finding, for those with low baseline academic performance.

Dozens of countries around the world have suffered civil conflicts in the past few decades, with the highest concentration in Sub-Saharan Africa. The direct humanitarian consequences of war for survivors are enormous in physical insecurity, loss of property, and psychological trauma. There may also be lasting economic development costs for societies that experience violent civil conflicts. And the international “spillover” effects of conflicts can be large for neighboring countries faced with refugee flows, lawlessness on their borders, and the illicit trades in drugs, arms, and minerals that proliferate in conflict zones. This insecurity has foreign policy implications for the United States along multiple dimensions. But what causes this insecurity and what can be done about it? In this chapter, I first describe recent academic research that finds a strong link leading from poverty to violence in less developed countries. I then lay out some of the implications of this core finding for public policy and in particular for the design of foreign aid.

Many contend that President Bush's reelection and increased vote share in 2004 prove that the Iraq War was either electorally irrelevant or aided him. We present contrary evidence. Focusing on the change in Bush's 2004 showing compared to 2000, we discover that Iraq casualties from a state significantly depressed the President's vote share there. We infer that were it not for the approximately 10,000 U.S. dead and wounded by Election Day, Bush would have won nearly 2% more of the national popular vote, carrying several additional states and winning decisively. Such a result would have been close to forecasts based on models that did not include war impacts. Casualty effects are largest in "blue" states. In contrast, National Guard/Reservist call-ups had no impact beyond the main casualty effect. We discuss implications for both the election modeling enterprise and the debate over the "casualty sensitivity" of the U.S. public.

We use a randomized evaluation of a Kenyan deworming program to estimate peer effects in technology adoption and to shed light on foreign aid donors' movement towards sustainable community provision of public goods. Deworming is a public good since much of its social benefit comes through reduced disease transmission. People were less likely to take deworming if their direct first-order or indirect second-order social contacts were exposed to deworming. Efforts to replace subsidies with sustainable worm control measures were ineffective: a drug cost-recovery program reduced take-up 80 percent; health education did not affect behavior, and a mobilization intervention failed. At least in this context, it appears unrealistic for a one-time intervention to generate sustainable voluntary local public goods provision.

Hundreds of millions of children in less developed countries suffer from poor health and nutrition. Children in most less developed countries also complete far fewer years of schooling, and learn less per year of schooling, than do children in developed countries. Recent research has shown that poor health and nutrition among children reduces their time in school and their learning during that time. This implies that programs or policies that increase children's health status could also improve their education outcomes. Given the importance of education for economic development, this link could be a key mechanism to improve the quality of life in less developed countries. Many researchers have attempted to estimate the impact of child health on education outcomes, but there are formidable obstacles to obtaining credible estimates. Data are often scarce, although much less scarce than in previous decades. Even more importantly, there are many possible sources of bias when attempting to estimate relationships between child health and education. This Chapter provides an overview of what has been learned thus far. Although significant progress has been made, much more research is still needed -- especially in estimating the long term impact of child health status on living standards. The...

Anemia is among the most widespread health problems for children in developing countries. This paper evaluates the impact of a randomized health intervention delivering iron supplementation and deworming drugs to Indian preschool children. At baseline, 69 percent were anemic and 30 percent had intestinal worm infections. Weight increased among assisted children, and preschool-participation rates rose by 5.8 percentage points, reducing absenteeism by one-fifth. Gains were especially pronounced for those most likely to be anemic at baseline. Results contribute to a growing view that school-based health programs are an effective way of promoting school attendance in less developed countries.
