This paper analyses the role of information in the search process. Ibuild a simple model of a good with two random … which neither affect expected utility norits variance. These changes have a great impact on the search behaviour …:the customer may start to search the characteristics and buy the goodeven if she did not do so before. The optimal search rule is …

. If two agents search simultaneously, the incentive tocontinue searching is affected by the information found by theother … agent. This forces the principal to leave rents to theagents. If agents search sequentially, the reward can be …

This paper builds a consumer search model where the cost of going back to stores already searched is explicitly taken … into account. We show that the optimal search rule under costly recall is very different from the optimal search rule under … perfect recall. Under costly recall, the optimal search behaviour is nonstationary and, moreover, the reservation price is not …

I examine a search model a la' Burdett and Judd (1983). Consumers are embedded in a consumers network, they may costly … search for price quotations and the information gathered are non-excludable along direct links. This allows me to explore the … effect of endogenous consumers externalities on market functioning. I first show that when search costs are low consumers …
