摘要:An updating rule specifies how an agent reacts to information. It is Blackwell monotone if more information is always better for an agent in any decision problem and strictly Blackwell monotone if, in addition, every strict information improvement is strictly better in some decision problem. Bayes's law is strictly Blackwell monotone. Within a broad class of updating rules-those that distort Bayesian posteriors in a signal-independent manner-it is the only strictly Blackwell-monotone updating ...

摘要:This paper investigates the weekly evolution of skills as measured by unique data from a widely emulated early-childhood home-visiting program in rural China. The design of the study avoids input endogeneity issues and lack of comparable measures of skills that plague previous studies. Skills, nominally classified as the same, in fact, do not appear to share a common unit scale across levels. They are produced by skill- and life cycle-stage-specific learning processes. A novel dynamic stochast...

摘要:Using a natural experiment from a retail gasoline antitrust case, we study how asymmetric information sharing affects oligopoly pricing. Empirically, price competition softens when, following case settlement, information sharing shifts from symmetric to asymmetric, with one firm losing access to high-frequency granular rival price data. We provide theory and empirics illustrating how strategic ignorance creates price commitment, leading to higher price-cost margins. Using a structural model, w...

摘要:We develop a model of competition in prices and infrastructure among mobile network operators. Although consolidation increases market power, it can lead to more efficient data transmission due to economies of scale, which we derive from physical principles. After estimating our model with French consumer and infrastructure data, equilibrium simulations reveal that while prices decrease with the number of firms, so do download speeds. Our framework also allows us to quantify the impact of spec...

摘要:We study the macroeconomic implications of asymmetric information in capital markets. We build a model in which heterogeneous capital is traded in illiquid markets, with sellers better informed about its quality than buyers. Asymmetric information distorts the terms of trade for sellers of high-quality capital, who list higher prices and accept lower trading probabilities to signal their type. Guided by the model, we measure these distortions from the relationship between listed prices and tra...

摘要:Algorithm designers increasingly care not only about accuracy but also about fairness across predefined groups. We study the trade-off between these objectives and characterize it by a fairness-accuracy frontier: the set of outcomes that cannot be simultaneously improved in both dimensions. The shape of this frontier is governed by a simple property of the inputs, which we call group skew. In particular, reducing accuracy for both groups to increase fairness is justified if and only if inputs ...

摘要:We develop and estimate a structural model of arbitration, accounting for asymmetric risk attitudes and learning. Using data on public sector wage disputes in New Jersey, we compare the efficiency of two popular arbitration formats: final offer and conventional. We find that although conventional arbitration hinders the transmission of case-relevant information from the disputants to the arbitrator, this format outperforms final offer arbitration by affording discretion to select awards. We al...

摘要:State and local governments in the United States compete to attract firms by offering discretionary subsidies. I use a private value English auction to model the subsidy bidding process and quantify the welfare effects of competition. The allocation of rents between states and firms depends on the heterogeneity in states' valuations for firms and the substitutability of locations. I find that competition increases welfare by less than 5% over a subsidy ban, and states compete away the surplus,...

摘要:We combine classic occupational choice (Roy model) and frictionless matching (following Sattinger) to explain earnings by occupation and firm in a way that is consistent with double assignment. In our model, within-firm inequality is globally nonzero whenever there is asymmetry in the revenue function or the occupational skill distribution across occupations. Occupational earnings overlap each other, and, unlike in the Roy model, the distributions of potential earnings are endogenous. In line ...
