摘要：We study two interventions for poor and underemployed Ethiopian youth: a $300 grant to spur self-employment, and a job offer to an industrial firm. Each one is designed to help overcome two common barriers to employment: financial market imperfections and matching frictions. We find significant impacts on occupational choice, income, and health in the first year. After five years, however, we see no evidence of long run effects of either intervention. The grant led short-run increases in self-...

摘要：Do users value a free technology less than one they pay for? In a two-stage randomized trial of improved grain storage technology in India, we test whether subsequent user willingness-to-pay is affected by free distribution compared to a small positive price. We find paying an initial price of zero has a strong negative effect on users' long-run willingness-to-pay but is not associated with differences in either reported use or benefits derived from the technology. The lower valuation implies ...

摘要：Index insurance has been seen as an important tool for managing the risks faced by farmers in developing countries but uptake has been disappointingly low. Basis risk is often cited as one of the main reasons for the lack of uptake. We investigate the role of basis risk in greater depth by considering contracts that allow farmers to choose the level of the index that triggers an indemnity in addition to coverage. We show that risk averse farmers will select trigger levels to protect against ca...

摘要：This paper studies costly conflict over private and public goods. Oil is an example of the former, political and civil rights an example of the latter. Our theory predicts that groups in conflict are likely to be small when the prize is private, and large when the prize is public. We examine these implications empirically using a global dataset of conflict at the ethnic group level. Our theoretical predictions find significant confirmation in this setting, and the analysis sheds new light on g...

摘要：As part of their commitments under the WTO's Agreement on Trade Facilitation, many developing countries will adopt risk management, a strategy for selecting import shipments for inspection. In this paper we formalize key enforcement issues related to risk management. We argue that the complexities of international trade oversight mean that inspecting agencies lack certainty about the conditional probability that a given shipment will comply with import regulations. Ambiguity of this sort is li...

摘要：We study how the structure of tournament incentive schemes in education can influence the level and distribution of student outcomes. Through a field experiment among upper-primary students in Malawi, we evaluate two scholarship programs: a Population-based scholarship that rewarded overall top performers on an exam and a Bin-based scholarship that rewarded the top performers within smaller groups of students with similar baseline scores. We find that the Population-based scholarship decreased...

摘要：During the period 2003-2016, China's infrastructure investment as a share of GDP outpaced, by a large margin, the average GDP share of entire government investment in advanced, developing, or emerging economies. A dynamic multi-sector model is constructed to assess the growth effects of this extraordinary investment episode. The model features sectoral heterogeneity in infrastructure intensity and positive externalities from aggregate infrastructure for firms and consumers. Along the model's t...

摘要：Several African countries have recently centralized their agricultural markets by launching a commodity exchange. What will be the impact of such a move? Who will be the winners and the losers? We develop a simple search model to study the impact of introducing a commodity exchange in a village economy where traders and farmers exchange on a bilateral basis. We study the efficiency gains from moving from the status quo to a trading regime where farmers have the option of selling their produce ...

摘要：This paper investigates the differential impacts of a unique car restriction policy - the car purchase lottery in Beijing - on the housing markets across locations within the city. I use a difference-in-differences approach to compare heterogeneous neighborhoods before and after the implementation of the policy. Housing prices experience a relative increase at locations closer to common destinations (employment centers: 0.7% per kilometer; primary schools: 3.3% per kilometer) and with better a...

摘要：I study the welfare effects of trade in the presence of large firms producing multiple varieties. Large multiproduct exporters dominate trade flows and their scope decisions have new implications for the welfare gains from trade. Using exporter-level data from 11 source countries, I document two stylized facts for large multiproduct exporters. First, the product scope increases with the level of development of the destination proxied by per capita income. Second, as evidence of cannibalization...
