Biography
Renos Vakis is a Lead Economist with the Poverty and Equity Global Practice where he co-leads the Mind, Behavior, and Development Unit (eMBeD). The unit integrates behavioral science in the design of anti-poverty policies in a wide range of issues such as financial inclusion, early childhood development, social protection, health and education. As a member of the Living Standards Measurement Study (LSMS) team in the Development Data Group of the World Bank, he also conducts experiments to improve household survey measures of behavioral dimensions of well-being. He has written extensively on issues related to poverty dynamics and mobility, risk management, social protection, market failures and rural development, especially in Latin America and South Asia and has led the design of impact evaluation of anti-poverty interventions in various settings. Most recently, he has completed a book on Chronic Poverty in Latin America and the Caribbean. Renos has also taught economics at Johns Hopkins University (SAIS). He holds a Ph.D. from the University of California, Berkeley.

Cash Transfers, Behavioral Changes, and Cognitive Development in Early Childhood : Evidence from a Randomized Experiment
(World Bank, Washington, DC, 2008-10)A variety of theories of skill formation suggest that investments in schooling and other dimensions of human capital will have lower returns if children do not have adequate levels of cognitive and social skills at an early age. This paper analyzes the impact of a randomized cash transfer program on cognitive development in early childhood in rural Nicaragua. It shows that the program had significant effects on cognitive outcomes, especially language. Impacts are larger for older pre-school age children, who are also more likely to be delayed. The program increased intake of nutrient-rich foods, early stimulation, and use of preventive health care-all of which have been identified as risk factors for development in early childhood. Households increased expenditures on these inputs more than can be accounted for by the increases in cash income only, suggesting that the program changed parents' behavior. The findings suggest that gains in early childhood development outcomes should be taken into account when assessing the benefits of cash transfer programs in developing countries. More broadly, the paper illustrates that gains in early childhood development can result from interventions that facilitate investments made by parents to reduce risk factors for cognitive development. -

Spatial Specialization and Farm-Nonfarm Linkages
(World Bank, Washington, DC, 2008-04)Using individual level employment data from Bangladesh, this paper presents empirical evidence on the relative importance of farm and urban linkages for rural nonfarm employment. The econometric results indicate that high return wage work and self-employment in nonfarm activities cluster around major urban centers. The negative effects of isolation on high return wage work and on self-employment are magnified in locations with higher agricultural potential. The low return nonfarm activities respond primarily to local demand displaying no significant spatial variation. The empirical results highlight the need for improved connectivity of regions with higher agricultural potential to urban centers for nonfarm development in Bangladesh. -

Improving Gender and Development Outcomes through Agency : Policy Lessons from Three Peruvian Experiences
(Lima: World Bank, 2013-07)Peruvian public policy is currently focused on economic growth with social inclusion. The Ministry of Development and Social Inclusion (MIDIS)-created in October 2011-leads the sector and promotes evidence-based public policy using three strategic guidelines: 1) matching criteria and mechanisms for the selection of areas and target population, 2) generation of instruments for inter-sectorial and inter-governmental result-based coordination, and 3) activation of monitoring and evaluation procedures to measure interventions' progress and results. This study is about the incredible and frequently underestimated role of agency-the ability to make choices to achieve desired outcomes-in economic development. The authors share the view that agency has inherent value for development: it is an attribute and manifestation of development, or using Sen's words, it is constituent to development. This study however, focuses on the instrumental role of agency for more tangible manifestations of development, such as, poverty reduction and economic growth. It attempts to show that expanding individual agency is a powerful catalyst for improving welfare, as measured by these concrete and widely used metrics of policy success. Moreover, it argues that in many cases, improving development outcomes through agency is highly cost-effective. This study centers on several policy initiatives in Peru, which as will be subsequently shown, have improved the agency of their beneficiaries. The purpose of this study is twofold. First, it aims at bridging this information gap, providing a review of evidence that shows how the psychological components of agency, such as aspirations and self-esteem, can effectively contribute to more traditional development objectives-ranging from higher investments in human capital to increased income. Second, the study reviews and synthesizes research on several policy interventions in Peru, which have empowered their beneficiaries. In this way, the study aims to derive practical recommendations on how to incorporate psychological elements of agency into policy interventions in order to achieve better development outcomes. The study is structured as follows: the next section discusses the concept of agency, providing examples of its broad role in achieving development objectives. The following section reviews the quantitative and qualitative research that served as the basis for this study and elaborates on the methodologies used to derive the conclusions presented in the ensuing section. The last section synthesizes the conclusions of the review of different interventions in Peru into six practical 'policy lessons'. -

Wealth Gradients in Early Childhood Cognitive Development in Five Latin American Countries
(World Bank, Washington, DC, 2014-02)Research from the United States shows that gaps in early cognitive and noncognitive abilities appear early in the life cycle. Little is known about this important question for developing countries. This paper provides new evidence of sharp differences in cognitive development by socioeconomic status in early childhood for five Latin American countries. To help with comparability, the paper uses the same measure of receptive language ability for all five countries. It finds important differences in development in early childhood across countries, and steep socioeconomic gradients within every country. For the three countries where panel data to follow children over time exists, there are few substantive changes in scores once children enter school. These results are robust to different ways of defining socioeconomic status, to different ways of standardizing outcomes, and to selective non-response on the measure of cognitive development. -

Cash Transfers, Behavioral Changes, and Cognitive Development in Early Childhood : Evidence from a Randomized Experiment
(American Economic Association, 2012-07)Cash transfer programs have become extremely popular in the developing world. A large literature analyzes their effects on schooling, health and nutrition, but relatively little is known about possible impacts on child development. This paper analyzes the impact of a cash transfer program on early childhood cognitive development. Children in households randomly assigned to receive benefits had significantly higher levels of development nine months after the program began. There is no fade-out of program effects two years after the program ended. Additional random variation shows that these impacts are unlikely to result from the cash component of the program alone. -

Left Behind: Chronic Poverty in Latin America and the Caribbean
( 2016-07-20)One out of every five Latin Americans—about 130 million people—have never known anything but poverty, subsisting on less than US$4 a day throughout their lives. These are the region's chronically poor, who have remained so despite unprecedented inroads against poverty in Latin America and the Caribbean since the turn of the century. This book takes a closer look at the region’s entrenched poor, who and where they are, and how existing policies need to change to effectively assist the poor. The book shows significant variations of rates of chronic poverty across and within countries. The book posits that refinements to the existing policy toolkit —as opposed to more programs—may come a long way in helping the remaining poor. These refinements include intensifying efforts to improve coordination between different social and economic programs, which can boost the income-generation process and deal with the intergenerational transmission of chronic poverty by investing in early childhood development. In addition, there is an urgent need to adapt programs to directly address the psychological toll of chronic poverty on people’s mindsets and aspirations, which currently undermines the effectiveness of existing policy efforts. -

You Are What (and Where) You Eat: Capturing Food Away from Home in Welfare Measures
(World Bank, Washington, DC, 2015-05)Consumption of food away from home is rapidly growing across the developing world. Surprisingly, the majority of household surveys around the world haven not kept up with its pace and still collect limited information on it. The implications for poverty and inequality measurement are far from clear, and the direction of the impact cannot be established a priori, since consumption of food away from home affects both food consumption and the poverty line. This paper exploits rich data on food away from home collected as part of the National Household Survey in Peru, shedding light to the extent to which welfare measures differ depending on whether they properly account for food away from home. Peru is a relevant context, with the average Peruvian household spending 28 percent of their food budget on food away from home by 2010. The analysis indicates that failure to account for the consumption of food away from home has important implications for poverty and inequality measures as well as the understanding of who the poor are. First, accounting for food away from home results in extreme poverty rates that are 18 percent higher and moderate poverty rates that are 16 percent lower. These results are also consistent, in fact more pronounced, with poverty gap and severity measures. Second, consumption inequality measured by the Gini coefficient decreases by 1.3 points when food away from home is included, a significant reduction. Finally, inclusion of food away from home results in a reclassification of households from poor to non-poor status and vice versa: 20 percent of the poor are different when the analysis includes consumption of food away from home. This effect is large enough that a standard poverty profile analysis results in significant differences between the poverty classification based on whether food away from home is included or not. The differences cover many dimensions, including demographics, education, and labor market characteristics. Taken together, the results indicate that a serious rethinking of how to deal with the consumption of food away from home in measuring well-being is urgently needed to properly estimate and understand poverty around the world. -

The Behavioral Professional: Improving Decision-Making and Performance in the Public Sector
(Washington, DC : World Bank, 2022)Over the past decade, governments, multilateral organizations, and think tanks have been increasingly using behavioral science as an additional tool to understand and tackle complex policy challenges in several sectors. Yet despite this increase in the use of behavioral science for policy design, little attention has been given so far to those individuals responsible for designing and implementing public policies and programs: policy professionals. This note aims to achieve three objectives. first, it highlights recent examples building on work done by the eMBeD team and the World Bank at large on how behavioral bottlenecks can hinder key development goals, from ensuring inclusive and equitable education for all (SDG4) to ensuring good health and well-being (SDG3), among others. Second, the note presents a behavioral framework highlighting the individual, group and institutional contexts that affect policy professionals. Finally, it showcases the relevance of the behavioral approach to a broad range of areas - including public service design, corruption and accountability, service design, access and delivery, civil servants’ performance - by pinpointing common bottlenecks faced, and potential solutions to overcome them. -

Intra-generational Mobility and Repeated Cross-Sections : A Three-country Validation Exercise
( 2011-12-01)This paper validates a recently proposed method to estimate intra-generational mobility through repeated cross-sectional surveys. The technique allows the creation of a "synthetic panel" -- done by predicting future or past household income using a set of simple modeling and error structure assumptions -- and thus permits the estimation of lower and upper bounds on directional mobility measures. The authors validate the approach in three different settings where good panel data also exist (Chile, Nicaragua, and Peru). In doing so, they also carry out a number of refinements to the validation procedure. The results are broadly encouraging: the methodology performs well in all three settings, especially in cases where richer model specifications can be estimated. The technique does equally well in predicting short and long-term mobility patterns and is robust to a broad set of additional "stress" and sensitivity tests. Overall, the paper lends support to the application of this approach to settings where panel data are absent. -

You Are What (and Where) You Eat: Capturing Food Away from Home in Welfare Measures
(Elsevier, 2017-10)Consumption of food away from home is rapidly growing across the developing world, and will continue to do so as GDP per person grows and food systems evolve. Surprisingly, the majority of household surveys have not kept up with its pace and still collect limited information on it. The implications for poverty and inequality measurement are far from clear, and the direction of the impact cannot be established a priori. This paper exploits rich data on food away from home collected as part of the National Household Survey in Peru, to shed light on the extent to which welfare measures differ depending on whether food away from home is accounted for or not. Peru is a relevant context, with the average Peruvian household spending over a quarter of their food budget on food away from home since 2010. The analysis indicates that failure to account for this consumption has important implications for poverty and inequality measures as well as the understanding of who the poor are. First, accounting for food away from home results in extreme poverty rates that are 18 percent higher and moderate poverty rates that are 16 percent lower. These results are also consistent, in fact more pronounced, with poverty gap and severity measures. Second, consumption inequality measured by the Gini coefficient decreases by 1.3 points when food away from home is included – a significant reduction. Finally, the inclusion of food away from home results in a reclassification of households across poor/non-poor status – 20 percent of the poor are different, resulting in small but significant differences in the profile of the poor in dimensions such as demographics, education, and labor market characteristics. Taken together, the results indicate that a serious rethinking of how to deal with the consumption of food away from home in measuring well-being is urgently needed to properly estimate and understand poverty around the world.
