摘要：We document that U.S. employment polarization in the 1980-2017 period is largely generated by women. In addition, we provide evidence that the increase of employment shares at the bottom of the skill distribution is generated in market sectors producing services representing home production substitutes. We use a calibrated macroeconomic model to show that a rising skill premium induces high-skilled women to participate more in the labor market, reduce home working hours, and demand more home s...

摘要：Can the optimal tariff be zero for a growing large country? To pursue the possibility, we extend the Rivera-Batiz-Romer lab-equipment model of endogenous technological change to include asymmetric countries, import tariffs, and either homogeneous or heterogeneous firms. Each country's domestic revenue share is a sufficient statistic for its long-run growth rate, but it is not for its long-run welfare. A unilateral tariff reduction by either country always increases the balanced growth rate. A ...

摘要：This paper develops a spatial equilibrium model with skill heterogeneity and agglomeration forces that stem from local idea exchange. I structurally estimate the model using American census data to study policy effects on real wage inequality between and within college and noncollege workers. Using the estimated model, I find: (1) Skill composition and local spillovers, respectively, account for 30% and 70% of the city-level relationship between productivity and employment. (2) Recent skill-bi...

摘要：Investigating a unique large data set, we find that automobile insurance policyholders are more likely to encounter accidents during the last month of the insurance policy term than during any other month. Our interpretation is that this effect is driven by the sunk cost fallacy held by policyholders, which exacerbates their moral hazard. The explanation is that in the last month, policyholders may become concerned that they may waste the premiums paid upfront if they have not encountered an a...

摘要：Trade data are typically aggregated across space. In this article, we investigate the sensitivity of gravity estimation to spatial aggregation. We build a model in which micro regions are aggregated into macro regions. We then apply the model to the large literature on border effects in domestic and international trade. Our theory shows that aggregation leads to border effect heterogeneity. Larger regions and countries are systematically associated with smaller border effects. We test our theo...

摘要：I study how initial wealth affects lifetime earnings inequality when labor markets are frictional. To do this, I construct a model life-cycle model with search frictions, incomplete markets, and endogenous human capital accumulation. In the model, incomplete markets prevent low-wealth workers from smoothing consumption, causing them to accept low pay jobs while unemployed. In anticipation, they build savings instead of human capital while employed. This amplifies the importance of initial weal...

摘要：We propose endogenous, value preserving (VP) welfare weights as an alternative to equal weights utilitarianism. VP weights require that the contribution of an agent's endowments to social welfare is proportional to the contribution of the final allocation to his welfare. Under three axioms, the per unit contribution of a good to welfare is shown to equal the gradient of the welfare function. VP weights coincide with Negishi weights in frictionless environments but prescribe redistribution towa...

摘要：The large and growing industry of price comparison websites (PCWs) or web aggregators is poised to benefit consumers by increasing competitive pricing pressure on firms by acquainting shoppers with more prices. However, these sites also charge firms for sales, which feeds back to raise prices. I find that introducing any number of PCWs to a market increases prices for all consumers, both those who use the sites, and those who do not. I then use my framework to identify ways in which a more com...

摘要：This article provides identification and estimation methods for a model of contracting with externalities and imperfect information. In this model, one principal offers a contract of trade quantity to each of multiple agents, and the negotiated payment for each agent is determined via Nash bargaining. Beliefs matter due to the privacy of bilateral contracting and the externalities from the dependence of each agent's payoff on all agents' trade quantities. We provide a test to determine whether...

摘要：This article estimates the importance of temptation for consumption smoothing and asset accumulation in a life-cycle model. We use two complementary estimation strategies: first, we estimate the model-implied Euler equation; second, we match liquid and illiquid wealth accumulation using the method of simulated moments. In both cases, we find that the utility cost of temptation is one-quarter of the utility benefit of consumption. Further, temptation is crucial for correctly estimating the elas...
