This paper surveys the literature on scale and scope economies in the water and sewerage industry. The magnitude of scale and scope economies determines the cost efficient configuration of any industry. In the case of a regulated sector, reliable estimates of these economies are relevant to...

This paper analyzes competition in a two-period differentiated-products duopoly in the presence of both switching costs and network effects. We show that they have opposite implications on the demand side, specially in the first period. Switching costs reduce demand elasticities and network...

We consider an industry where an upstream firm determines the size of a network used by two downstream firms. We contrast ownership unbundling and legal unbundling, where the upstream firm maximizes its total profit, including the profit of its downstream subsidiary(ies), but does not...

Regional sports networks (RSNs) have become among the most important and expensive programming carried by multi-channel video programming distributors (MVPDs), many of which have acquired RSNs in whole or in part. Under Nash bargaining theory, vertical integration creates incentives to charge...

We consider an industry where an upstream firm determines the size of a network used by two downstream firms. We contrast ownership unbundling and legal unbundling, where the upstream firm maximizes its total profit, including the profit of its downstream subsidiary(ies), but does not...

In this paper we analyze a network market in which it is beneficial for a producer to invite competitors to share a market, even when this is not needed in order to affect consumer beliefs. Because of the nature of such goods, the demand curve for network markets typically rises and then falls....

The internet presumably reduces search costs and creates an “efficient” market. Prior research quantifying the dispersion in the electronic market, however, has yielded mixed results. Some recent research has documented very low levels of dispersion in internet attributing it to the use of...

Television advertising levels in Europe are regulated according to the "Audiovisual Service Media Directive", where member states of the European Union usually impose stricter regulation on their Public Service Broadcasting (PSB) channels. The present model evaluates the effects of symmetric and...

While some studies have assumed that mature and well-established platforms do not exhibit feedback loop effects, other recent contributions have suggested that these effects may exist. Using a unique database that provides detailed information on both cardholder and merchant sides of the Spanish...

This paper reviews recent developments in online and mobile banking in the United States that provide bank account holders with low-cost interfaces to manage account-to-account electronic money transfers. The paper analyzes the emerging decentralized market in which A2A money transfers are...
