摘要：Despite growing enthusiasm, there is still much to be learned about how well energy-efficiency investments work in practice. Evidence is particularly lacking from low- and middle-income countries, despite a widespread view that these countries have many of the best opportunities. This paper evaluates a field trial in Mexico in which a quasi-experimental sample of new homes was provided with insulation and other energy-efficient upgrades. A novel feature of our study is that we deploy large num...

摘要：Smaller farms and plots appear more productive per hectare than larger ones in most developing country data. Using unique plot-level panel data from Uganda, with agricultural plots matched over a decade using geospatial location, we estimate the size-productivity relationship using variation in plot size over time under plot fixed effects, as well as variation in plot size within a farm, under household-period fixed effects. Like many other authors, we find that the observed inverse relationsh...

摘要：Numerous evaluations of conditional cash transfer (CCT) programs show positive short-term impacts, but there is only limited evidence on whether these benefits translate into sustained longer-term gains. This paper uses the municipal-level randomized assignment of a CCT program implemented for five years in Honduras to estimate long-term effects 13 years after the program began. We estimate intent-to-treat effects using individual-level data from the population census, which allows assignment ...

摘要：This paper estimates the effect of mass media on public willingness to pay (WTP) for better environmental quality. We exploit the exogenous shock of the environmental documentary Under the Dome with a regression discontinuity design by using its release as the assignment and the number of days away from the release date as the running variable. Using longitudinal survey data collected in Nanjing, China, we find that Under the Dome increases people's WTP for better air quality by 24.9%, which i...

摘要：Between 1964 and 1973, the U.S. dropped two million tons of bombs on Laos. As the legacy of war, unexploded ordnance (UXO) contaminates a quarter of villages. This paper studies the long-term impact of UXO on education, exploiting the instrumental variable that originates from the geography of U.S. bombing campaigns in Laos. It finds that bombing not only interrupts the education of wartime cohorts, but also has strong and persistent negative impacts on the education of postwar cohorts through...

摘要：Recent influential papers claim that single men's saving competition for marriage intensified by an increase in the male-to-female ratio in the pre-marital cohort explains 60 percent of the rise of China's aggregate household savings rate. In this paper, we analyze whether the marriage competition remains a first-order effect on saving, when another margin of adjustment to sex ratio imbalance, men's postponement of marriage, is considered. We construct a theoretical and quantitative life-cycle...

摘要：This paper examines the aggregate and distributional labor-market impacts of a large-scale marine environmental crisis caused by an industrial pollution in Vietnam. Combining labor force surveys with a novel satellite data on fishing-boat detection, the analysis finds negative and heterogeneous impacts on fishery incomes and employment, and uncovers interesting coping patterns. Satellite data suggest that the affected upstream fishers traveled north to unaffected area to continue fishing. Thes...

摘要：Using a quasi-experimental design and panel data from 2004 to 2014, I estimate how temporary 30% corporate income tax cuts affected firm investment, employment, profits, and tax revenue during the Global Financial Crisis in Vietnam. I find that investment increased during the policy year and came back to its pre-policy level after the policy ended. The evidence does not suggest there were any significant changes in employment. Reported profits of eligible foreign-owned firms doubled in the pol...

摘要：We provide evidence that dowry costs motivate son-preferring behaviors in India. Since gold is an integral part of dowry, we study parental responses to shocks in the world gold price. Exploiting monthly variation in gold prices across 35 years we find that monthly changes in gold prices lead to an increase in girl relative to boy neonatal mortality and that surviving girls are shorter. After the introduction of prenatal sex determination technology, we find that gold price shocks during pregn...

摘要：Does better population health lead to growth in per capita income? Theory is ambiguous and empirical evidence is very limited. In 2001, a steep fall in antiretroviral (ARV) drug prices triggered rapid and massive expansion of ARV therapy coverage in lower-income countries. Exploiting the sharp resultant changes in population health, I show that ARV therapy coverage expansion led to growth in GDP per capita. The positive effects on growth most likely persist for around four years. ARV therapy c...
