摘要：Utilizing a novel database including nearly 2.2 billion booking records in China, we examine whether people escape from pollution by traveling to cleaner places. Combining an instrumental variable approach with high- dimensional fixed effects, we find a 50-unit increase in the AQI gap between a city pair leads to a 1.30% (1.33%) increase in train and airline ticket bookings from the origin to the destination city departing within one day (2-7 days). In addition, the destination of such polluti...

摘要：We present a novel method-called risk equivalents-that uses a single measure to elicit discount rates while avoiding concerns about the shape of the utility function. The method is valid under discounted expected utility (DEU), and also under several of its behavioral extensions including more general models that account for a biased perception of time and risk (such as time- or likelihood -insensitivity). We implement the method in a field experiment in India measuring inter -temporal discoun...

摘要：Increasing evidence shows the significance of de jure land ownership in determining agricultural productivity, yet the causal evidence of the effectiveness of land rights is scarce. We leverage experimental variation induced by nudging Indian farmers to obtain formal land titles. We find that titling increases agricultural investments, crop productivity, and paddy profits. We identify the tenancy security as the potential channel for impact from titling on the labour market and collateral effe...

摘要：Educational market integration have become a common practice in various countries, changing potentially student's application and enrollment behavior. We implement a difference-indifference estimation exploiting student's geographic exposure to market integration in Chile to understand student's gain and losses from this process. Using administrative data, we show that the market integration process has no effect on overall university enrollment but changes the enrollment composition: new plat...

摘要：Theoretically, the welfare effects of cash-based assistance depend on how businesses respond to the demand shock and on resulting effects on prices. Such market effects have been largely overlooked in the literature. In this study, we examine the business and price effects of cash-based assistance to refugees in Kenya. Monthly restricted cash transfers worth 3 to 13 dollars were provided to 400,000 refugees in the form of digital money exclusively usable for food purchases at licensed shops. W...

摘要：We structurally estimate the firm-level frictions across prefectures in China and quantify their aggregate and distributional implications. Based on a general equilibrium model with input and output distortions and migration, we show that the firm-level frictions are less dispersed and less correlated with firm productivity in richer prefectures. Counterfactual exercises show that reducing the within-prefecture misallocation increases aggregate welfare, discourages migration toward large prefe...

摘要：In Central India, the Narmada River separates two regions that have been ruled by different types of government only during the colonial period, and for reasons independent of their initial economic development. I implement a spatial RDD on village population in the Nineteenth Century as well as in 1901, and I run the same model on proxies of welfare in 2015. My results highlight that divergence has realised where the river overlapped with the colonial border, but not in a neighbouring area wh...

摘要：This paper assesses the reliability of poverty maps derived from off-the-shelf remote-sensing data. Employing data for Malawi, it first obtains small area estimates of poverty by combining household expenditure survey data with population census data. It then ignores the population census and obtains a second poverty map by combining the survey with predictors of poverty derived from remote sensing data. The two approaches reveal the same patterns in the geography of poverty. However, there ar...

摘要：Using a nationally representative dataset from China, we exploit an event study approach to trace out the consequences of land expropriation on household economic behaviors and health outcomes. The expropriated rural households receive an average compensation per capita of over 6 thousand yuan (60 percent of pre-event income) immediately after expropriation and thus have a higher income level. Among the people in these households, the likelihood of working in the agricultural sector decreases ...

摘要：Did violence increase social distancing and decrease COVID-19 cases? We investigated the effects of massacres on social distancing and subsequent impacts on COVID-19 cases in Colombia. Using an augmented synthetic control method model, we find that massacres reduced human mobility toward parks by six percentage points compared to unaffected areas. However, we did not find significant changes in workplace mobility. Moreover, alterations in social interactions caused by the violence had minimal ...
