We consider vertical contracts where the retail market may involve search frictions. Minimum advertised price restrictions (MAP) act as a restraint on customers' information and so can increase search frictions in the retail sector. Such restraints, thereby, soften retail competition--an impact...

An upstream manufacturer can use minimum retail price maintenance (RPM) to exclude potential competitors. RPM lets the incumbent manufacturer transfer profits to retailers. If entry is accommodated, upstream competition leads to fierce down- stream competition and the breakdown of RPM. Hence,...

New Keynesian models of price setting under monopolistic competition involve two kinds of inefficiency: the price level is too high because firms ignore an aggregate demand externality, and when there are costs of changing prices, price stickiness may be an equilibrium response to changes in...

Entry represents a fundamental threat to cartels engaged in price fixing. We study the extent and effect of this behavior in the largest price fixing case in US history, which involves generic drugmakers. To do so, we link information on the cartel's internal operations to regulatory filings and...

We analyze tacit collusion in an industry characterized by cyclical demand and long-run scale decisions; firms face deterministic demand cycles and choose capacity levels prior to competing in prices. Our focus is on the nature of prices. We find that two types of price wars may exist. In one,...

Most of the theoretical work on collusion and price wars assumes identical firms and an unchanging environment, assumptions which are at odds with what we know about most industries. Further that literature focuses on the impact of collusion on prices. Whether an industry can support collusion...

Competition policy aims to prevent anticompetitive agreements and mergers, limiting the abusive exercise of market power. The formulation and application of this policy presents significant challenges, which include showing that proposed mergers are anticompetitive, proving that firms are...

Information frictions play a central role in the formation of household inflation expectations, but there is no consensus about their origins. We address this question with novel evidence from survey experiments. We document two main findings. First, individuals in lower-inflation contexts have...

I examine the outcomes of cases of entry by merchant shipping lines into established markets around the turn of the century. These established markets are completely dominated by an incumbent cartel composed of several member shipping lines. The cartel makes the decision whether or not to begin...

This paper examines the consequences of the 2015 reform on the London fixing in the interbank forex market, which resulted from finding and imposing a penalty on banks' collusive behavior around the fixing window. The banks changed their behavior after the reform, and the volume spike in the...
