Do we have effective competition between the gasoline's big five oligopolists (Aral, Shell, Esso, Total and Jet) and fringe gasoline stations? Using 2014 Market Transparency price data from 66 cities with populations between 60,000 and 100,000, we analyze which brands lead price increases, the...

We investigate the effects of passive backward acquisitions in their efficient upstream supplier on downstream firms' ability to collude in a dynamic game of price competition with homogeneous goods. We find that passive backward acquisitions impede downstream collusion. The main driver of our...

We analyze a sample of consumer-electronics products sold by the US NewEgg online-retailer to study the impact of Price Matching Guarantees (PMGs) policies on prices. By applying aDifference-in-Differences approach,we find that prices of the policy-adopting retailer increase by 4.7% during the...

Standard models of collusion require that all firms are forward-looking and strategic. When one firm displays naive behavior—i.e., when it is myopic, memoryless, or non-strategic—typical collusive strategies cannot be supported in equilibrium. Motivated by the increasing adoption of...

We study empirically the price effects of upstream cartels that sell through downstream retailers to final consumers. We focus on a German coffee producer cartel that colluded under two different regimes: (i) involving wholesale prices in 2003 and (ii) with additional resale price maintenance...

This paper examines the competitive effects of resale price maintenance (RPM) through inventory decisions under demand uncertainty. We focus on the Japanese publishing industry where RPM is allowed. We develop and estimate a model of RPM in which price and inventory are determined before demand...

Motivated by a recent competition policy debate on retailers' collusion in online marketplaces, this paper studies a simple model to shed light on the competitive and welfare effects of this conduct. I find that, when retailers sell their products through a monopolistic e-commerce platform,...

We analyze the best price clauses (BPCs) of online travel agents (OTAs) using meta-search price data of more than 45,000 hotels in different countries. Although OTAs apparently have not changed their standard commission rates following the partial ban of BPCs in Europe, we find that BPCs do...

We provide a theory of how RPM facilitate upstream cartels absent any information asymmetries using a model with manufacturer and retailer competition. Because retailers have an effective outside option to each manufacturer’s contract, the manufacturers can only ensure contract acceptance by...
