We consider a market model with n rational firms (doctors) and a continuum of boundedly rational consumers (patients). Following Spiegler (2006a), we assume that patients are not familiar with the market and rely on anecdotes. We analyze the price setting game played by doctors with given, different healing qualities. Doctors know their own quality, as well as the qualities of their competitors...

We analyze a model in which two profit-maximizing firms compete in two-attribute products over agents who follow a non-compensatory choice procedure that responds purely to ordinal quality rankings: sticking to a default option when no market alternative dominates another, and focusing on a random attribute when choosing by default is impossible. Our equilibrium analysis highlights the effect o...

I present a simple framework for modeling two-firm market competition, where each firm chooses a market alternative as well as a costless “marketing message”. Consumers follow a frame-dependent choice function, where the frame is a probabilistic function of the firms’ marketing messages. This framework embeds several recent models in the literature on markets with boundedly rational consumers. ...
