  摘要：This paper examines the impact of intellectual property judicial institutions on innovation, focusing on the intellectual property courts (IPCs) reform in China. We find that IPCs reform leads to a significant 22.6 % increase in the number of invention patents at the city level, equating to an average rise of 215 annually. Notably, we rule out the possibility of inter-region and intra-conglomerate transfer of patents, indicating that the effect of the IPCs reform on innovation is not a zero-su...
• Confined to stay: Migration restrictions, natural disasters, and poverty AI翻译

  摘要：How do restrictions to international migration affect communities' ability to cope with natural disasters? We exploit the implementation of an emigration ban for millions of Indonesians wanting to migrate to Saudi Arabia as a natural experiment. Our identification strategy relies on pre-determined migration networks and on the exogenous timing of the ban and of natural disasters. Using a panel of the universe of Indonesian villages and a triple difference approach, we demonstrate that poverty ...
• The agricultural productivity gap: Informality matters AI翻译

  摘要：The measured agricultural productivity gap (APG) in developing countries typically compares agriculture with the entire non-farm economy, implicitly treating the latter as homogeneous. In developing countries, most nonfarm employment is informal, concentrated in small, unregistered enterprises with low productivity. This paper compares the productivity of agriculture to the informal and formal non-farm sectors in India. Using Indian sectoral data from the India KLEMS database linked with natio...
• Beyond poverty reduction: Evidence from a multifaceted program on poverty, nutrition and child development AI翻译

  摘要：We study the impacts of a multifaceted program implemented in Burkina Faso that targets ultra-poor households with young children or pregnant women. The design includes a cash transfer program (T1), T1 plus animal transfer (T2) and T2 plus a nutrition bundle which includes fortified flour, a gardening kit and nutrition education (T3). We find that the program reduces extreme poverty in all treatment branches, but only T3 positively impacts child nutrition. T3 also impacts motor and cognitive d...
• The mismeasure of weather: Using earth observation data for estimation of socioeconomic outcomes AI翻译
  作者：Josephson, Anna; Michler, Jeffrey D.; Kilic, Talip; Murray, Siobhan

  摘要：The availability of weather data from remotely sensed earth observation (EO) products has reduced the cost to economists of including weather variables in econometric models. Weather variables are common instrumental variables used to predict socioeconomic outcomes and serve as an input into modeling crop productivity in rainfed agriculture. The use of EO data in econometric applications has only recently been met with a critical assessment of the suitability and quality of this data in econom...
• Do minimum wage hikes lead to employment destruction? Evidence from a regression discontinuity design in Argentina AI翻译
  作者：Abbate, Nicolas; Jimenez, Bruno

  摘要：In this study, we examine the impact of eight minimum wage increases in Argentina during the early 21st century by analyzing administrative records of registered employment. Utilizing a regression discontinuity design, we compare job separation rates between a group affected by the minimum wage hikes and a control group slightly out of their legal scope. Our findings indicate that, overall, these minimum wage hikes had no significant impact on separation rates. However, the 2008 increase trigg...
• From open to closed societies: Inequality, migration, and women's rights AI翻译

  摘要：We study six centuries of institutional change in the governance of the commons across over three hundred Italian communities. Wealthier communities, facing migration pressure due to unequal resource endowments, restricted access to common property resources by excluding women from membership, thereby limiting migration through marriage. Using archival data and an agent-based model, we show that this endogenous closure spread via a domino effect and persisted until a centralized Napoleonic ref...
• Saving an old regime with new elites? The unintended effects of co-opting foreign-educated councilors in China AI翻译

  摘要：How does the co-optation of foreign-educated elites influence local stability? This study exploits a quasiexperimental setting created by the establishment of provincial Consultative Bureaus in China in 1909 to examine the political consequences of integrating Japan-educated returnees into local governance. Using an original, prefecture-by-month panel dataset across 262 prefectures from 1901 to 1911, we find that co-opting foreign-educated elites produced unintended effects: it significantly r...
• Understanding social safety nets and intra-household food allocation: Experimental evidence from Bangladesh AI翻译

  摘要：Evidence shows that social protection can improve diets, but little is known about how impacts vary within households, the extent to which the modality of the transfer affects how it is distributed across all household members, whether adding training on the importance of nutrition and diets alters the way transfer resources are allocated within the household, relative to a transfer alone, and if differences in allocations are shaped by differences in livelihood opportunities. We use individua...
• Increasing women's empowerment: Evaluating two interventions in Uganda AI翻译

  摘要：We conduct a randomized controlled trial to test a novel intervention for increasing women's empowerment in Uganda. The intervention includes a within-household transfer of a productive asset, which has a lower cost than an external transfer. We find that transferring control of some of the household's sugarcane to the wife significantly increases her access to resources and decision-making power. We also document increases in women's empowerment arising from a cross-randomized couples' worksh...
