For a market with a finite number of agents, pairwise matching, and bargaining, it is shown that, even when the market is frictionless, the equilibrium is not necessarily competitive. It depends on the amount of information agents use. If their behavior is conditioned only on the sets of agents...

We explore how allowing votes to be traded separately of shares may affect the efficiency of corporate control contests. Our basic set-up and the nature of the questions continue the work of <xref ref-type="bibr" rid="bib15">Grossman and Hart (1980)</xref>, <xref ref-type="bibr" rid="bib17">Harris and Raviv (1988)</xref>, and Blair, Golbe and Gerard (1989). We consider three...

The model features a dynamic market in steady state in which prices ar e determined in first-price auctions. It combines competition over ti me, familiar from the pairwise meeting models, with instantaneous bid ding competition. It inquires how different properties of the model d etermine the...

We consider a market in which an expert must exert costly but unobservable effort to identify the service that meets the consumer's need. In our model, experts offer competing contracts and the consumer may gather multiple opinions. We explore the incentives that a competitive sampling of prices...

We develop a framework for modelling choice in the presence of framing effects. An extended choice function assigns a chosen element to every pair (A, f) where A is a set of alternatives, and f is a frame. A frame includes observable information that is irrelevant in the rational assessment of...

We develop a framework for modelling choice in the presence of framing effects. An "extended choice function "assigns a chosen element to every pair ("A", "f") where "A "is a set of alternatives, and "f "is a "frame". A frame includes observable information that is irrelevant in the rational...

An individual displays various preference orderings in different payoff-irrelevant circumstances. It is assumed that the variation in the observed preference orderings is the outcome of some cognitive process that distorts the underlying preferences of the individual. We introduce a framework...
