摘要：Many households are confined to remote rural villages in the developing world. This study examines the Anti-Poverty Relocation Program in China, considering the village-to-town relocation from agricultural to non-agricultural sectors induced by the program. While exploring a novel administrative data set on impoverished people in a Chinese county, we discovered that the program significantly increased the participants' income by 9.61%, driven mainly by the increase in wage income. The empirica...

摘要：Prices are fundamental to economists, but there is little guidance on how to collect accurate data on prices in developing countries. I compare antimalarial drug prices collected using three different approaches at outlets in Uganda: vendor inventory listings, prices reported by real customers, and standardized patient (mystery shopper, or SP) purchases. I find that prices collected from SPs and real customers are the same after accounting for the composition of drugs purchased, but prices rep...

摘要：Traditions can limit investment in early life health, even if they have been abandoned. We introduce data on historic twin infanticide and merge it with recent birth records from 23 African countries. We use the full sample and a border sample of adjacent societies with and without past twin infanticide. Both samples provide no evidence that past twin infanticide predicts greater differential twin mortality today. This null result is likely a consequence of suppression efforts by Africans, mis...

摘要：This paper shows that concerns about social stigma cause individuals to avoid HIV tests. People have inaccurate beliefs about the stigma environment but are open-minded about taking on new information. A simple message that shares the local community's true (low) degree of stigmatizing attitudes can help individuals overcome the stigma barrier and result in more testing. The information intervention led to 36% more HIV testing among those who had overestimated stigma. The treatment effect is c...

摘要：This paper analyzes the effect of mobile money adoption on tax revenue performance in a large sample of 104 developing countries over the period 1990-2019. Estimations, based on the entropy balancing method, show that mobile money significantly increases tax revenue in mobile money countries relative to non-mobile money countries. This result remains robust to various robustness tests and may depend on time perspective, the type of mobile money service, and some structural factors, including a...

摘要：Decision-making about fertility differs between monogamous and polygynous households. In an experiment in Burkina Faso that gives women access to free contraceptives, either alone or with their husband, involving the husband decreases contraceptive use among monogamous women, but not among polygynous women. Where there is co-wife rivalry, it increases contraceptive use. This is consistent with a model where monogamous women have a stronger preference for contraceptives than their husband, whil...

摘要：Does the internet enable the recruitment of transnational terrorists? Using geo-referenced population census data and personnel records from the Islamic State in Iraq and the Levant - a highly tech-savvy terrorist organization - this paper shows that internet access has facilitated the organization's recruitment of foreign fighters from Tunisia. The positive association between internet access and Daesh recruitment is concentrated among younger cohorts.

摘要：We study two interventions in Beijing, China, that provide patients with information on antibiotic resistance via text message to discourage the overuse of antibiotics. The messages were sent once a month for five months. One intervention emphasizes the threat to the recipient's own health and is found to have negligible effects. The other intervention, which highlights the overall threat to society, reduces antibiotics purchases by 17% in dosage without discouraging healthcare visits and othe...

摘要：I exploit the staggered introduction of 3G mobile Internet technology across South Africa to estimate its impact on political participation, electoral competition, voters' preferences, and protests. Combining granular coverage data with administrative records on municipal elections, I show that in 2016 mobile Internet availability caused a 2-percentage-point increase in voter turnout and a 3-percentage-point reduction in the vote share of the ruling party. The main opponents gained from mobile...

摘要：How does territorial control by organized crime groups affect the enforcement of public policies? We answer this question by studying the enforcement of social distancing policies in Rio de Janeiro during the COVID-19 crisis. Two criminal groups with distinct governance have de facto control over several areas of the city: drug trafficking organizations (DTOs) and paramilitary groups (PGs). While the former funds itself mainly through the drug business, the second obtains most of its profits f...
