Using a natural experiment from a retail gasoline antitrust case, we study how asymmetric information sharing affects oligopoly pricing. Empirically, price competition softens when, following case settlement, information sharing shifts from symmetric to asymmetric, with one firm losing access to...

We propose an attention-based mechanism for habit formation and contrast its predictions with those from Stigler and Becker's consumption-based mechanism. We develop a habit formation model that nests both mechanisms and structurally estimate it using data from a large-scale field experiment in...

Competition and consumer search costs can lead to price dispersion in an oligopoly. IO research has long identified the existence of search costs and estimated their distribution and is now beginning to study which consumers sit where in the distribution. This paper argues for a view of consumer...
