摘要：We provide a finite sample inference method for the structural parameters of Manski's semiparametric binary response model under a conditional median restriction. This is achieved by exploiting distributional properties of observable outcomes conditional on the observed sequence of exogenous variables. Moment inequalities conditional on the size n sequence of exogenous covariates are constructed, and the proposed test statistic is a monotone function of violations of the corresponding sample m...

摘要：I introduce a generic method for inference about a scalar parameter in research designs with a finite number of heterogeneous clusters where only a single cluster received treatment. This situation is commonplace in difference-in-differences estimation, but the test developed here applies more broadly. I show that the test controls size and has power under asymptotics where the number of observations within each cluster is large but the number of clusters is fixed. The test combines weighted, ...

摘要：This paper proposes that strong institutions provide comparative advantage in clean industries, and thereby improve a country's environmental quality. I study financial, judicial, and labour market institutions. Five complementary tests evaluate and assess implications of this hypothesis. First, industries that depend on institutions are clean. Second, strong institutions increase relative exports in clean industries. Third, an industry's complexity helps explain the link between institutions ...

摘要：Industrial policies are widely used across the world. In practice, designing and implementing these policies is a complicated task. In this paper, we assess the long-term performance of different industrial policy instruments, which include production subsidies, investment subsidies, entry subsidies, and consolidation policies. To do so, we examine a recent industrial policy in China aiming to propel the country's shipbuilding industry to the largest globally. Using firm-level data from 1998 t...

摘要：This article studies the impact of the arbitrator selection process on consumer outcomes. Using data from consumer arbitration cases in the securities industry over the past two decades, where we observe detailed information on case characteristics, the randomly generated list of potential arbitrators presented to both parties, the selected arbitrator, and case outcomes, we establish several motivating facts. These facts suggest that firms hold an informational advantage over consumers in sele...

摘要：Complementarities between partners' characteristics are often held responsible for the patterns of assortative mating observed in marriage markets along different dimensions, such as race and education. However, when the marriage market is segmented into racially and educationally homogeneous clusters, people naturally have more match opportunities with their likes. In this paper, we build an empirically tractable dynamic matching model with endogenous separation and remarriage. In every perio...

摘要：Quality provision is often low in many developing markets, and firms commonly lack a reputation for quality. This article examines this issue both theoretically and empirically in the context of retail watermelon markets in China. I first demonstrate the existence of significant asymmetric information on quality between sellers and buyers, as well as the absence of a quality premium at baseline. To explain this, I develop a theoretical model that highlights the role of consumer beliefs and cos...

摘要：This paper documents that production networks play an essential role in the job search and matching process. We document five facts about worker mobility in production networks using employer-employee data matched with the universe of firm-to-firm transactions for the Dominican Republic: (1) workers move between buyers and suppliers almost twice as much as predicted by standard labour market characteristics, (2) movers between buyers and suppliers experience larger earnings increases than othe...

摘要：Diversity can pose fundamental challenges to state building and development. The Tanzanian Ujamaa policy-one of post-colonial Africa's largest state-building experiments-addressed these challenges by resettling a diverse population in planned villages, where children received political education. We combine differences in exposure to Ujamaa across space and age to identify long-term impacts of the policy. Analysis of contemporary surveys shows persistent, positive effects on national identity ...

摘要：We study the effect of diminishing search frictions in markets with adverse selection by presenting a model in which agents with private information can simultaneously contact multiple trading partners. We highlight a new trade-off: facilitating contacts reduces coordination frictions but also the ability to screen agents' types. We find that, when agents can contact sufficiently many trading partners, fully separating equilibria obtain only if adverse selection is sufficiently severe. When th...
