We collected data on children at the beginning of the school year, and applied 12 tests of math, language and executive function (EF) at the end of the year. All teachers were filmed teaching for a full day, and the videos were coded using a wellknown classroom observation tool, the Classroom Assessment Scoring System (or CLASS). We find substantial classroom effects: A one-standard deviation increase in classroom quality results in 0.11, 0.11, and 0.07 standard deviation higher test scores in language, math, and EF, respectively. Teacher behaviors, as measured by the CLASS, are associated with higher test scores. Parents recognize better teachers, but do not change their behaviors appreciably to take account of differences in teacher quality.

Health and income are strongly correlated both within and across countries, yet the extent to which improvements in income have a causal effect on health status remains controversial. We investigate whether short-term fluctuations in aggregate income affect infant mortality using an unusually large data set of 1.7 million births in 59 developing countries. We show a large, negative association between per capita GDP and infant mortality. Female infant mortality is more sensitive than male infant mortality to negative economic shocks, suggesting that policies that protect the health status of female infants may be especially important during economic downturns. © 2011 The President and Fellows of Harvard College and the Massachusetts Institute of Technology.

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expressed in this paper are entirely those of the authors.

A large body of research indicates that child development is sensitive to early-life environments, so that poor children are at higher risk for poor cognitive and behavioral outcomes. These developmental outcomes are important determinants of success in adulthood. Yet, remarkably little is known about whether poverty-alleviation programs improve children's developmental outcomes. We examine how a government-run cash transfer program for poor mothers in rural Ecuador influenced the development of young children. Random assignment at the parish level is used to identify program effects. Our data include a set of measures of cognitive ability that are not typically included in experimental or quasi-experimental studies of the impact of cash transfers on child well-being, as well as a set of physical health measures that may be related to developmental outcomes. The cash transfer program had positive, although modest, effects on the physical, cognitive, and socioemotional development of the poorest children in our sample.

The Peruvian Social Fund (FONCODES) was created by President Alberto Fujimori in 1991 with the stated objectives of generating employment, alleviating poverty, and improving access to social services. This article uses province-level data on monthly expenditures, socioeconomic indicators, and electoral outcomes to analyze political influences on the timing and geographic distribution of FONCODES expenditures between 1991 and 1995. I reach three main conclusions. First, these expenditures increased significantly before national elections. Second, FONCODES projects were directed at provinces in which the marginal political effect of expenditures was likely to be largest. Third, these projects favored the poorest provinces, which suggests that the program also had a redistributive function. The results are robust to a large number of specifications and controls. The Peruvian data support predictions made in the literature on political business cycles as well as the literature on political influences on the allocation of discretionary funds.

Do aggregate income shocks, such as those caused by macroeconomic crises or droughts, reduce child human capital? The answer to this question has important implications for public policy. If shocks reduce investments in children, they may have a long-lasting impact on poverty and its intergenerational transmission. The authors develop a simple framework to analyze the effects of aggregate economic shocks on child schooling and health. They show that the expected effects are theoretically ambiguous because of a tension between income and substitution effects. They then review the recent empirical literature on the subject. In richer countries, like the United States, child health and education outcomes are counter-cyclical: they improve during recessions. In poorer countries, mostly in Africa and low-income Asia, the outcomes are procyclical: infant mortality rises and school enrollment and nutrition fall during recessions. In the middle-income countries of Latin America, the picture is more nuanced: health outcomes are generally procyclical and education outcomes counter-cyclical. Each of these findings is consistent with the simple conceptual framework. The authors discuss possible implications for expenditure allocation. JEL codes: I30, J13, O15 Investments in children's health and education have long-term consequences. In both the United States and the United Kingdom, low levels of cognitive development in childhood, measured by a child's performance in tests administered as early as 22 months of age, have been shown to be important predictors of adult wages (Currie and Thomas 1999; Case and Paxson 2008). In developing countries, long-term panels suggest that adverse experiences in early childhood result in worse outcomes in adulthood. A well-known study in Jamaica shows that children who were stunted (had height-forage two standard deviations or more below that of a reference population) in early childhood were significantly more likely to have deficits in cognition and school achievement in adolescence

Long regarded as a region beset by macroeconomic instability, high inflation, and excessive poverty and inequality, Latin America has undergone a major transformation over the last 20 years. The region has seen improved macroeconomic management and substantial and sustained reductions in poverty and inequality. In this paper, we argue that social policy, including human capital and education, social insurance, and redistribution, need special attention if achievements of the last two decades are to be sustained and amplified. Starting in the mid 1990s, many governments in the region introduced a variety of programs, including noncontributory pensions and health insurance, and cash transfers targeted to the poor. Social spending in Latin America increased sharply. These policies have been widely praised, and we believe they have resulted in substantial improvements in the lives of the poor in the region. However, a more nuanced view shows some worrisome trends. Moving forward, we believe it is necessary to pay much closer attention to the quality of services, particularly in education; to the incentives generated by the interplay of some programs, particularly in the labor market; to a more balanced intertemporal distribution of benefits, particularly between young and old; and to sustainable sources of finance, particularly to the link between contributions and benefits.
