摘要：How does violence affect social capital? I argue that its impact depends on two factors: (i) the ability to identify the perpetrating group, and (ii) the intensity of the violence. These factors help to reconcile the seemingly contradictory effects of violence on social capital presented in the literature. I study this question in the context of Colombia by exploiting changes in violence attributed to cross-border shocks on coca markets in neighboring countries interacted with a novel index of...

摘要：Menstrual hygiene practices in low-income countries are often limited by lack of finances and information, with potentially adverse consequences for women's well-being and workplace outcomes. In a randomized controlled trial with around 1,900 female workers from four Bangladeshi garment factories, we relax both constraints individually and jointly by providing free sanitary pads and information on hygienic menstrual practices. Both access to sanitary pads and information improve menstrual prac...

摘要：The number of Global Mobile Inventors (GMIs), inventors moving across borders during their career, has increased more than tenfold over the past two decades, and the corridors of mobility have shifted towards a growing presence of emerging markets. We document that GMIs that have patented in a given technology before moving are 70% more likely to be among the pioneering inventors in that technology once they arrive at destination, which we interpret as evidence of knowledge diffusion across bo...

摘要：We study the effect of energy and transport policies on pollution in two developing country cities. We use a quantitative equilibrium model with choice of housing, energy use, residential location, transport mode, and energy technology. Pollution comes from commuting and residential energy use. The model parameters are calibrated to replicate key variables for two developing country cities, Maputo, Mozambique, and Yogyakarta, Indonesia. In the counterfactual simulations, we study how various t...

摘要：We study the effects of an increase in post-secondary educational opportunities on teen fertility by exploiting policy-induced variation from Ser Pilo Paga (SPP), a generous college financial aid program in Colombia that dramatically expanded college opportunities for low-income students. Our preferred empirical approach uses a triple difference design that leverages variation in the share of female students eligible for the program across municipalities and the fact that the introduction of S...

摘要：This paper identifies export accelerations at the country pair -product level that are large enough to drive aggregate export growth in the medium run. In a sample of 100 countries, these export big hitsare rare, less than 2 percent of all export spells, yet account for over two-thirds of export growth in a given country. The paper then explores their microfoundations using matched customs -census firm -level data for France. We find that typically, two firms are sufficient to generate a big h...

摘要：This paper examines the impacts of vocational training for persons with disabilities (PWDs). In heavily mined areas of rural Cambodia, adults with limb amputation or paralysis were randomly assigned to either a treatment group (invited to participate in an intensive training program in mechanics and services) or a control group (not invited to participate). Over 30% of PWDs in the treatment group participated in the program and none in the control group did so. Although being assigned to the t...

摘要：This paper estimates the welfare gains from the construction of rural roads that connect agricultural villages to market centers. I take theoretical predictions from Ricardian trade models to a rich high spatial resolution micro data on agricultural production from Ethiopia, which coincides with a period of extensive rural road construction. I estimate that the road construction resulted in an approximately 13% increase in real agricultural income, on average, and show that this increase is at...

摘要：We study the impacts of market access on forest loss in Ghana through a program designed to increase smallholder participation in oil palm commodity markets. Improved market access is facilitated through production contracts in which smallholders receive credit to establish production, a guaranteed price and quantity for the contract duration, and output pickup at the village. Using a variety of difference-in-differences approaches, we find substantial increases in forest loss in targeted vill...

摘要：This paper measures the effect of seed quality misperceptions on bidding behavior and demand for high-quality seed using an information-provision experiment within an incentive-compatible Vickery Second Price (SPA) auction mechanism that mimics seed purchasing decisions in the presence of seed market frictions. We find that most individuals are prone to quality misperception and revise their bids upwards (downwards) in response to positive (negative) quality signals. In addition, by exploiting...
