We analyze competition in product lines by multi-product oligopolists that have preferential access to a local market but can supply a rival's market by incurring distance costs. We show that the width and degree of overlap in the product lines is greater in large markets and when the products...

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...

How do changes in competitive intensity affect trade patterns? Some cartels may find it advantageous to eliminate cross-hauling and divide markets geographically. We exploit a quasi-natural experiment associated with increased antitrust enforcement to determine if market division strategies were...

We illustrate conditions under which a trade platform selling its own products alongside third-party sellers benefits or harms consumers. This benefits consumers by lowering prices in a suite of models: a gatekeeper platform facing a competitive fringe of sellers, when fringe sellers also have...

We analyze firms' entry, production and hedging decisions under imperfect competition. We consider an oligopoly industry producing a homogeneous output in which risk-averse firms face an entry cost upon entering the industry, and then compete in Cournot with one another. Each firm faces...

Markets for many commodities are characterized by imperfectly competitive production as well as substantial storage by speculators who are attracted by significant price volatility. We examine how speculative storage affects the behavior of an oligopoly producing a commodity for which demand is...

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...

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...

This paper examines the effect of price matching guarantees (PMGs) on market outcomes in a sequential search model. PMGs are simultaneously chosen with prices and some consumers (shoppers) know the firms’ decisions before buying, while others (non-shoppers) enter a shop before observing the...

We investigate the R&D portfolio choices of multiproduct firms. When a firm increases cost-reducing R&D investment in a given product, its rivals will modify their entire R&D portfolios by reducing R&D investments in that particular product and increasing R&D investments in other competing...
