We introduce a simple new model of sequential search among finitely many options that fits many economic applications …, and so resolves major selection effects. 1. Search intensifies over time, as one increasingly exercises the current option … search models: which stochastic changes lead one to search longer? Answer: more dispersed payoffs.3. The stationary search …

We formulate and solve dynamic programming models extending search theory to (1) multiple indivisible units and (2 … (2). The seller can partially exercise orders - hence, search at the margin.The optimal selling strategy adjusts as the … inframarginal units. This depresses reservation prices at the margin. For instance, model (1) subsumes the wage search model, but we …

We explore costly sequential search among finitely many risky options, and an outside option. Payoffs are the sum of a … known and hidden random factor.(a) We resolve a long open question about how riskier payoffs impact search duration …: expected search time is higher for more dispersed idiosyncratic noise.(b) Since options differ ex ante, we incorporate …
