I study a model of oligopolistic competition in which consumers search for prices, but have no idea about the underlying price distribution. Consumers' behaviour satisfies four consistency requirements such that beliefs about the underlying distribution maximize Shannon entropy. I derive the...

This paper examines the optimal sequencing of sales in the presence of network externalities. A firm sells a good to a group of consumers whose payoff from buying is increasing in total quantity sold. The firm selects the order to serve consumers so as to maximize expected sales. It can serve...

This paper examines the effect of price matching guarantees (PMGs) in a sequential search model. PMGs are simultaneously chosen with prices and some consumers (shoppers) know the firms' decisions before buying, while others (non-shoppers) enter a shop first before observing a firm's price and...

In this paper we analyse a model of oligopolistic competition in which consumers search without priors. Consumers do not have prior beliefs about the distribution of prices charged by firms and thus try to use a robust search procedure: they minimise the loss relative to the searcher, who knows...

This paper analyzes dynamic selection effects in markets for credence goods where price structures are determined by a regulator or by central management. There are different types of consumers and each type requires a different service or treatment level. We show that for a large class of price...

When consumers do not know the prices at which different firms sell, they often also do not know production costs. Consumer search models which take asymmetric information about production costs into account continue focusing on reservation price equilibria (RPE) and their properties. We argue...
