Collaborative Research: Learning and Efficient Matching

项目摘要这是一个关于不确定条件下动态匹配环境下社会剩余的实现和分配的项目。项目I提出了一个动态的双边匹配模型，当比赛双方都有关于比赛价值的不完全信息时。由随机变量给出的两个个体之间每个匹配的值。通过重复采样可以获得有关每个可行匹配的真实值的更多信息。该项目分析了当比赛伙伴在价格上存在竞争时的跨期定价和比赛形成。在劳动力市场的应用中，确定了有效地将工人分配到任务的充分条件。项目II关注的是动态竞价行为，其假设是，在一开始，所有各方都不知道该物品的真实价值，而在每个时期被授予该物品的投标人则收到关于其真实价值的额外(私人)信息。项目III继续研究在由不同偏好的买家组成的市场中体验良好扩散的模型。我们研究购买者根据可支配收入和其他特征的不同而决定采用一种新产品的决定。分析了不同的进入和创新战略，适用于以下环境：新产品表现为(I)对现有产品的潜在改进，或(Ii)潜在价值不高于现有产品的替代品。

Project Abstract This is a project to conduct three projects concerned with the realization and division of social surplus in dynamic matching environments under uncertainty. Project I presents a dynamic and two-sided matching model when there is imper fect information about the value of the match on both sides of the match. The value of each match between two individuals given by a random variable. More information about the true value of each feasible match can be acquired by repeated sampling. The project analyzes intertemporal pricing and match forma tion when there is competition in prices for the match partners. In an application to the labor market, sufficient conditions for efficient assignment of workers to tasks are identified. Project II is concerned with dynamic bidding behavior under the assumption that the true value of the object is unknown to all parties at the outset, while the bidder that is awarded the object in each period receives additional (private) information about its true worth. Project III continues research on a model of experience good diffusion in a market consisting of buyers with heterogeneous preferences. We study the decisions to adopt a new product by buyers that differ according to their disposable income and other characteristics. Different entry and innovation strategies are analyzed for environments where the new product presents (i) a potential improvement over the established product or (ii) is potentially a substitute of no higher value than the established product.
