This paper investigates price setting when firms produce with increasing returns and customers are imperfectly informed about prices but customers can search. It is shown that there exists a unique randomization equilibrium where each customer is offered a random price by each firm known to him....

Traditional monetary models of hyperinflation suffer from severe stability problems: equilibria with realistic comparative-static properties are unstable while those with unrealistic comparative statics are stable. In the present paper I develop a model of hyperinflation which is based on an...

We develop a market model which explains how prices react to short-run demand variations when the number of active price-setting firms is held fixed on its long-run level. We assume that for each firm the average production cost function is U-shaped, that customers are imperfectly informed about...

In this paper I investigate the effect of different stages of international trade on market structure and prices when production involves overhead cost, markets are intransparent, and customers have to search for offers. I show that two stages have to be distinguished: a first stage where each...
