Abstract:

The levels of violence in Mexico have dramatically increased in the last few years due to structural changes in the drug trafficking business. The increase in the number of drug trafficking organizations (DTOs) fighting over the control of territory and trafficking routes has resulted in a substantial increase in the rates of homicides and other crimes. This study evaluates the economic costs of drug-related violence. We propose electricity consumption as an indicator of the level of municipal economic activity and use two different empirical strategies to test this. To estimate the marginal effect of violence in the rate of homicides (per 100,000 inhabitants) we use an instrumental variable regression created by Mejía, Castillo and Restrepo (2012). For the average municipality, the marginal negative effect of the increase in homicides rates is substantive for earned income and the proportion of business owners, but not for energy consumption. Although negative and statistically significant, the effects are mild for labor participation. We also employ the methodology of synthetic controls to evaluate the effect that inter-narco wars have on local economies. The analysis indicates that the drug wars in those municipalities that saw dramatic increases in violence between 2006 and 2010 significantly reduced their energy consumption in the years after the change occurred, which is interpreted as a significant reduction in GDP per capita for these municipalities.

Speaker Bio:

Gabriela Calderon holds a Ph.D. in Economics from Stanford University. Her research interests include policies that affect gender differences in developing countries, policy evaluation, violence in Latin America and the effect of institutions and governance on the provision of public goods and health/education outcomes. She did her master's degree in economic theory and bachelor's degree in economics at the Instituto Tecnológico Autónomo de México. Currently, in the Program on Poverty and Governance, her research analyzes the way institutions and democracy affect the provision of public goods, and the impact they have on health outcomes like infant mortality trends. She is also studying the effects of government interventions that combat drug-trafficking organizations over violence in Mexico.

Her research has focused on the topics of development, public finance, and the evaluation of public policy programs in Mexico. For example, during the summers of 2009/2010, she conducted a field experiment in Zacatecas, Mexico with Giacomo de Giorgi, an assistant professor from Stanford University, and Jesse Cuhna, a former Stanford student. The main task was to evaluate the impact of financial literacy classes on underprivileged women entrepreneurs in the region. To successfully complete an evaluation in an untreated region, they proposed collaborating with the Mexican NGO CREA on a joint project. They contacted local interviewers, trained them, and identified all women entrepreneurs in the 17 communities, in which we conducted the experiment. Preliminary results suggest that the female entrepreneurs who were randomly assigned to treatment earned higher profits, had larger revenues, and served a greater number of clients. They also found that they were more likely to implement formal accounting techniques.

She has also studied programs that are not randomly assigned as an experiment. For example, she has analyzed the effects of a national policy in Mexico of child care services, called Estancias Infantiles para apoyar a Madres Trabajadoras (EI), using administrative, census and household data. Her empirical research strategy identifies the effects of the program on both the men and women who were eligible for the program. She used time, location and eligibility variation, and considered a major threat to identification of the actual effects: for example, a manufacturer who moves into a municipality at approximately the same time as the EI program and who happens to disproportionately demand the skills of women who were eligible to the program happened to have. To ensure that such scenarios do not affect her results, she chose not triple difference strategy, in which all ineligible people are treated as “controls” for the EI-eligible families. Instead, she employs Synthetic Control Methods, using the same methodology as Abadie and Gardeazabal (2003) and Abadie, Diamond and Hainmueller (2010) to ensure that her control group has the same mix of skills and preferences as the EI-eligible group. She adapted the Synthetic Control Method to analyze repeated cross-sectional household data, which are data that are typically available in developing countries

OBJECTIVE: To determine whether children in rural areas have worse health than children in urban areas after liver transplantation (LT). STUDY DESIGN: We used urban influence codes published by the US Department of Agriculture to categorize 3307 pediatric patients undergoing LT in the United Network of Organ Sharing database between 2004 and 2009 as urban or rural. Allograft rejection, patient death, and graft failure were used as primary outcome measures of post-LT health. Pediatric end-stage liver disease/model of end-stage liver disease scores >20 was used to measure worse pre-LT health. RESULTS: In a multivariate analysis, we found greater rates of allograft rejection within 6 months of LT (OR 1.27; 95% CI 1.05-1.53) and a lower occurrence of posttransplantation lymphoproliferative disorder (OR 0.64; 95% CI 0.41-0.99) in patients in rural areas. The difference in allograft rejection was eliminated at 1 year of LT (OR 1.18; 95% CI 0.98-1.42). Rural location did not impact other outcome measures. CONCLUSION: We conclude that rural location makes a negative impact on patient health within the first 6 months of LT by increasing the risk for allograft rejection, although patients in rural areas may have lower rates of developing posttransplantation lymphoproliferative disorder. Long-term adverse health effects were not seen.

Currently, more than two-thirds of the population in Africa must leave their home to fetch water for drinking and domestic use. The time burden of water fetching has been suggested to influence the volume of water collected by households as well as time spent on income generating activities and child care. However, little is known about the potential health benefits of reducing water fetching distances. Data from almost 200 000 Demographic and Health Surveys carried out in 26 countries were used to assess the relationship between household walk time to water source and child health outcomes. To estimate the causal effect of decreased water fetching time on health, geographic variation in freshwater availability was employed as an instrumental variable for one-way walk time to water source in a two-stage regression model. Time spent walking to a household’s main water source was found to be a significant determinant of under-five child health. A 15-min decrease in one-way walk time to water source is associated with a 41% average relative reduction in diarrhea prevalence, improved anthropometric indicators of child nutritional status, and a 11% relative reduction in under-five child mortality. These results suggest that reducing the time cost of fetching water should be a priority for water infrastructure investments in Africa.

In this paper we report the results of a randomized controlled trial designed to measure the impact of a parental training program on the nutritional status of primary school students in rural Shaanxi Province, in Northwest China. Using hemoglobin (Hb) levels as the outcome variable, we first measure the overall impact of a nutritional training program, then measure the impact separately by gender. We use both descriptive and multivariate analyses.

The results for the descriptive and econometric results were robust and consistent with the literature. Overall, we find no impact on students’ Hb levels when we trained their parents about undernutrition and anemia. In both the descriptive and multivariate results, there was no difference in the change of Hb levels between control and treatment students. Parents in the treatment group did learn more about anemia than parents in the control group, but this increased knowledge did not lead to sharp changes in behavior, in general. We did find, however, that there was a measurable impact of parental training on the Hb levels of female students. In both the descriptive and econometric results we found that the Hb levels of female students rose more than that of male students, and that this difference was statistically significant. We conjecture that the parents of female students may have recognized from the training that they were not providing their daughters with sufficient nutrition. Our data show that parents in the treatment group responded by increasing the daily provision of meat, fish, eggs and beans, relative to parents of girls in the control group.

Professor Hidehiko Ichimura of the University of Tokyo will share recent results from his research on the health of older adults and the retirement process in Japan. His research draws upon a unique data source, the Japanese Study of Aging and Retirement (JSTAR). This rich dataset provides information on how middle-aged and elderly Japanese live in terms of economic, social, and health outcomes, and how these interact with their family status. The JSTAR project aims to provide longitudinal data enabling detailed policy-relevant comparisons to other industrialized countries (e.g. the Survey on Health, Aging and Retirement in Europe, the U.S. Health and Retirement Study, the English Longitudinal Study on Aging, and similar surveys now launched in Korea, China, and India).

Professor Ichimura received his BA in economics from Osaka University in 1981 and his PhD in economics for the Massachusetts Institute of Technology in 1988. He has taught at the University of Minnesota, the University of Pittsburgh, and University College London. He is currently a professor in the Graduate School of Public Policy and Graduate School of Economics at the University of Tokyo.
