摘要：This paper provides evidence on the scope and incentive mechanisms of long-term relationships in the US truckload freight industry. In this setting, shippers and carriers engage in repeated interactions under fixed-rate contracts that allow for inefficient opportunism. The main dynamic mechanism involves shippers using the threat of relationship termination to deter carriers from short-term opportunism. This threat and the potential of future rents induce more carrier cooperation. We test this...

摘要：We examine the effects of overlapping ownership among existing firms deciding whether to enter a product market. We show that in most cases-and especially when overlapping ownership is already widespread-an increase in the extent of overlapping ownership will harm welfare by softening product market competition, reducing entry, and thereby (in contrast to standard results) inducing insufficient entry and magnifying the negative impact of an increase of entry costs on entry. Overlapping ownersh...

摘要：We consider the identification of empirical models of supply and demand with imperfect competition. We show that a restriction on the covariance between unobserved demand and cost shocks can resolve endogeneity and identify the price parameter. We demonstrate how to employ this approach in estimation, and we compare it to the method of instrumental variables. Our formal results also indicate that weaker covariance restrictions can bound the price parameter. We illustrate the covariance restric...

摘要：We propose a method to augment conventional demand estimation approaches with crowd-sourced data on the product space. Our method obtains triplets data (product A is closer to B than it is to C) from an online survey to compute an embedding-i.e., a low-dimensional representation of the latent product space. The embedding can either replace data on observed characteristics in mixed logit models, or provide pairwise product distances to discipline cross-elasticities in log-linear models. We illu...

摘要：Preferences for mixing can reveal ambiguity perception and attitude on a single event. The validity of the approach is discussed for multiple preference classes, including maxmin, maxmax, variational, and smooth second-order preferences. An experimental implementation suggests that participants perceive almost as much ambiguity for the stock index and actions of other participants as they do for the Ellsberg urn, indicating the importance of ambiguity in real-world decision-making. (JEL C72, D...

摘要：Empirical search cost estimates are often large and increasing in the size of the transaction. We conduct an online search experiment in which we manipulate the price scale while keeping the physical search effort per price quote constant. Additionally, we obtain a direct measure of subjects' opportunity costs of time. Using a standard search model, we confirm that search cost estimates are large and increasing in the price scale. We then modify the model to incorporate context effects with re...

摘要：We study information aggregation with a decision-maker aggregating binary recommendations from symmetric agents. Each agent's recommendation depends on her private information about a hidden state. While the decision-maker knows the prior distribution over states and the marginal distribution of each agent's recommendation, the recommendations are adversarially correlated. The decision-maker's goal is choosing a robustly optimal aggregation rule. We prove that for a large number of agents for ...

摘要：We model decisions to apply for college admission, attend job auditions, or run for C-suite positions as costly entry into meritocracies, where the entrant with the highest ability wins a reward. Ability is privately known and players generically differ in commonly known characteristics such as ability distributions, entry costs, or payoffs from winning. Any infinitesimal difference leads to wildly different equilibrium entry probabilities, explaining large dispersion in representation of comp...

摘要：Half of all transactions in the $6 trillion market for manufactured goods in the United States were intermediated by wholesalers in 2012, up from 32 percent in 1992. Seventy percent of this increase is due to the growth of superstar firms-the largest 1 percent. Estimates based on detailed administrative data show that the rise of the largest firms was driven by an intuitive linkage between their sourcing of goods from abroad and an expansion of their domestic distribution network to reach more...

摘要：In the United States, electoral districts must be equipopulous. This requirement is known as the one man, one vote doctrine. We propose welfare-based justifications for this requirement under the economic view, according to which voters care about the policy, and under the political view, according to which voters care about representation. Both justifications assume that the districter is partisan. If the districter is benevolent, one man, one vote is harmless under the economic view but may ...
