The arm's length principle states that the transfer price between two associated enterprises should be the price that would be paid for similar goods in similar circumstances by unrelated parties dealing at arm's length with each other. This paper examines the effect of the arm's length...

By analysing an infinitely repeated game where unit costs alternate stochastically between low and high states and where firms follow a price-matching punishment strategy, we demonstrate that the best collusive prices are rigid over time when the two cost levels are sufficiently close. This...

We examine the incentives of a monopolistic search engine, funded by advertising, to provide reliable search results. We distinguish two types of search results: sponsored and organic (not-paid-for). Organic results are most important in searches for online content, while sponsored results are...

We consider a two-period model with two sellers and one buyer. Although we assume it is efficient for the buyer to purchase from both sellers in each period, we show that when the buyer's valuations are inter-temporally linked and at least one seller is financially constrained, exclusion can...

In this paper we examine how trade liberalization affects collusive stability in the context of multimarket interactions. The model we consider is a segmented-markets duopoly with differentiated goods in which price-setting firms pool their incentive constraints across markets to sustain their...

When commodity prices rise, wholesalers and retailers of products derived from basic commodities respond by passing along at least a portion of the price increase to consumers. In this paper we examine whether firms respond differently to positive commodity price shocks than to negative...

We examine the consumer welfare effect of a firm's partial ownership of a competitor and compare the implications of alternative forms of divestiture. We identify conditions under which turning voting shares into non-voting shares is preferable to selling the shares to the firm's current...

In procurement settings, mergers among suppliers reduce buyers' choice sets and can harm buyers by eliminating their preferred supplier or reducing their negotiating leverage. I develop a stochastic economic model that predicts the effects of mergers based on information that commonly is...

Theoretical work has suggested that contact between firms in different markets can facilitate tacit collusion. Empirical work on this link has been limited. We address the paucity of empirical evidence with a novel plant-level dataset for the cement industry during the Great Depression. We find...
