Search Design and Broad Matching
We study decentralized mechanisms for allocating firms into search pools. The pools are created in response to noisy preference signals provided by consumers, who then browse the pools via costly random sequential search. Surplus-maximizing search pools are implementable in symmetric Nash equilibrium. Full extraction of the maximal surplus is implementable if and only if the distribution of con...
متن کاملBroad Matching and the Market for Search Platforms∗
We construct a two-sided market model, in which consumers can only provide a noisy signal of the type of product they want. Each signal functions as a platform, to which (multi-homing) firms get access if they pay its competitive market price. A "broad match" function, designed ex-ante by the search intermediary, links signals to one another: a firm that attaches itself to one signal (by paying...
متن کاملMatching, Search, and Heterogeneity
This paper explores the efficiency of decentralized search behavior and matching patterns in a model with ex ante heterogeneity and a constant returns to scale search technology. We show that a linear tax or subsidy on search intensity decentralizes the social optimum. In the absence of the tax, high productivity agents are too willing to match, yet they search too little. Low productivity agen...
متن کاملAssortative Matching and Search
In Becker’s (1973) neoclassical marriage market model, matching is positively assortative if types are complements: i.e. match output f(x, y) is supermodular in x and y. We reprise this famous result assuming timeintensive partner search and transferable output. We prove existence of a search equilibrium with a continuum of types, and then characterize matching. After showing that Becker’s cond...
متن کاملDistributed Search and Pattern Matching
Peer-to-peer (P2P) technology has triggered a wide range of distributed applications including file-sharing, distributed XML databases, distributed computing, server-less web publishing and networked resource/service sharing. Despite of the diversity in application, these systems share common requirements for searching due to transitory nodes population and content volatility. In such dynamic e...
