Reducing fixed cost duplication - a common justification for concentrated market structure - motivated the US government to relax the number of radio stations a firm could operate in any local market. After deregulation the number of firms per market decreased. The implied cost saving depends on...

It is often claimed that large buyers wield buyer power.  Existing theories of this effect generally assume upstream monopoly.  Yet the evidence is strongest with upstream competition.  We show that upstream competition can yield buyer power for large buyers by generating supplier-level...

This paper surveys new research concerning bargaining within supply chains and its implications for buyer power.  The paper explores the implications of the research on supermarket supply chains for primary, secondary and private-label branded goods.  The empirical base in support of the...

This paper evaluates alternative strategic models of competition and market structure in online retailing, and makes comparisons with traditional retailing. Online consumers are less concerned than traditional consumers about spatial characteristics and more concerned about hidden quality...

This paper develops an asymmetric price setting oligopoly model of store opening and closure decisions in the UK supermarket industry which is estimated using a survey of consumer choices and a dataset of store characteristics. The model is used to examine the strategic local entry and exit...

When a supermarket cuts its price for one product category it may increase the demand for another by drawing more consumers into the store. We call this a multi-category effect. We contrast the prominent role that the multi-category nature of supermarket shopping has enjoyed in competition...

We study vertical contracting through bargaining between an upstream supplier and downstream retailers. We consider the effect of supplier uncertainty as to final volumes on the efficient bargains struck. Uncertainty causes retail price effects: large buyers wield countervailing power (deliver...

This paper considers buyer power in the presence of upstream competition to supply a homogeneous product. A likely consequence of upstream competition is that each supplier is uncertain of its final output, because it does not know how many downstream buyers will select it as a seller. We...

I use a consumer choice model for the British supermarket industry to compare the incentives of firms, selecting store characteristics, with the interests of consumers. I perform a series of counterfactual changes to store size and location and rank the alternatives by gains per unit of fixed...

While online consumers are less concerned than traditional consumers about firm location, they may be more concerned about unobservable quality and, to signal this, online retailers rely more on advertising than traditional retailers. Imperfect price competition may arise because of vertical...
