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...

We consider a dynamic competition game among three players, where each player can vary the extent of his competition on a per-rival basis. We call such competition targeted. We show that if the players are myopic, the weaker players eventually lose the game to their strongest rival. If instead...

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...

When limited to heterosexual marriage, agents of different genders are not guaranteed to harvest the same payoff even conditional on having the same type, and even if all other factors, such as search costs or the distribution of partner types, are the same across genders. If same-sex marriage...

We consider an information design problem when the sender faces ambiguity regarding the probability distribution over the states of the world, the utility function and the prior of the receiver. The solution concept is minimax loss (regret), that is, the sender minimizes the distance from the...

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...
