摘要：Can schools use the internet to promote reading and learning? We provided Wikipedia access to randomly-selected students in Malawian boarding secondary schools. Students used the online resource broadly and intensively, and found it trustworthy, including for information about news and safe sex. We find a 0.10 sigma impact on English exam scores, and a higher impact among low achievers (0.20 sigma). Students used Wikipedia to study Biology, and exam scores increased for low achievers (0.14 sig...

摘要：In this paper, we examine the effect of computer-assisted learning on students' long-term development. We explore the implementation of a large ed-tech intervention that connected some of China's best teachers to more than 100 million rural students through satellite internet. By leveraging the staggered installation of computer equipment in different areas of the country, we find evidence that exposure to the program improved students' academic achievement, labor performance, and computer usa...

摘要：We use plant level census data to identify spillovers from FDI in Ethiopia's manufacturing sector. Spillovers are identified by comparing changes in total factor productivity (TFP) among domestic plants in districts where a large greenfield foreign plant produces and districts where FDI in the same industry was licensed but not yet operational. Over the four years starting with the year of the FDI opening, the TFP of domestic plants is 11 percent higher in treated districts, employment in dome...

摘要：Farmers in developing countries routinely misperceive or misreport input quality for various reasons, which introduces substantial measurement error in farm survey data. In this paper, we motivate and illustrate, both analytically and empirically, the inferential and behavioral implications of misperception and misreporting using a unique crop variety identification data from Nigeria. Using a non-parametric framework for testing the presence of measurement error, we show that crop variety misc...

摘要：Globalization can lead to either conservation or depletion of natural resources that are used in the production of traded goods. Rising prices may lead to better resource management. Alternatively, stronger incentives to extract these resources may exacerbate their decline. I examine the impact of agricultural trade promotion on the groundwater extraction in India using nationally representative data from 1996-2005. I find evidence that trade promotion led to increased extraction of the reserv...

摘要：This paper asks how academic breaks after high school affect individuals' college and labor market outcomes. We exploit a policy that altered academic calendars in two regions of Colombia, which caused thousands of high school graduates to have to wait an extra semester to start college. Using administrative data and a synthetic control design, we show that the academic break caused many students to forgo enrolling in college at all. The academic break reduced the early-career earnings of stud...

摘要：In this paper, we provide systematic evidence of how historical religious institutions affect the rule of law. In a difference-in-differences framework, we show that districts in Pakistan where the historical presence of religious institutions is higher, rule of law is worse. This deterioration is economically significant, persistent, and likely explained by religious leaders gaining political office. We explain these findings with a model where religious leaders leverage their high legitimacy...

摘要：This paper reports on the effects of a training-based intervention seeking to increase household engagement in poultry production in Burkina Faso, analyzing data from a large-scale cluster randomized trial in which 1798 households in 60 communes were observed over a period of three years. The intervention SELEVER - entailing a short series of trainings for households as well as capacity building for local animal health and credit services - had little effect on household poultry production and...

摘要：We study the effect of women's public leadership in times of crisis. We use a regression discontinuity design in close mayoral races between male and female candidates to understand the impact of having a woman as a mayor during the COVID-19 pandemic in Brazil. Female leadership reduced deaths and hospitalizations per 100 thousand inhabitants while increasing enforcement of non-pharmaceutical interventions. These results are not due to measures taken before the pandemic or other observable may...

摘要：Labor productivity differences between developing and developed countries are much larger in agriculture than in non-agriculture. We show that differences in agricultural composition across countries explain a substantial part of these labor productivity differences. To this end, we group agricultural products into two sectors: capital-intensive and labor-intensive agriculture. As the economy develops and capital accumulates, the price of labor-intensive agricultural goods relative to capital-...
