The Rule of Reason, which has come to dominate modern antitrust law, allows defendants the opportunity to justify their conduct by demonstrating “procompetitive” effects. Seizing the opportunity, defendants have begun offering increasingly numerous and creative explanations for their...

Should the FTC have allowed Zillow to acquire its foremost rival, Trulia? It is increasingly well-accepted that digital platforms tend toward dominance in their immediately adjacent relevant-product markets. Google, for example, has long held a majority share of the markets for general-search...

Economists typically assume that demand curves are downward sloping. We present evidence that increasing the price of an item from $44 to $49 may increase unit demand by up to 30%. This effect is substantial, has broad application, is easily replicated, and contradicts the downward-sloping...

We have developed a method for directly learning relative preferences from histories of comparison information without an intermediate utility computation. Our method infers preferences that are rational in a psychological sense, where agent choices result from Bayesian inference of what to do...

This paper contributes to the theory of rational choice under multiple criteria. We perform a preliminary study of the properties of decision made by the sequential application of rational choices. This is then used to obtain a characterization of set-valued choice functions that are rational by...
