On the incentives to form strategic coalitions in ATM markets

This paper studies ATM coalitions in retail banking. We ask when it is profitable for banks to make agreements which ban direct ATM transaction fees. In the case of a coalition banks loose income from ATM transactions but relax competition in the banking market. We find that such agreements are profitable when the interchange fee is sufficiently high. When banks can collude on the interchange they always form a coalition. Coalitions may harm consumers but lead to higher total welfare. Moreover, we find that smaller banks have larger incentives to form ATM coalitions. Investment in ATM networks is typically higher with a coalition. --Banking competition,ATM networks,collusion

Liberalization of Opening Hours with Free Entry

This paper studies competition in prices and opening hours in a model with free entry. It is shown that under free competition a market failure arises: Entry is excessive and opening hours are under-provided. Restrictions on opening hours aggravate this failure. I analyze the impact of a liberalization of opening hours. The model predicts that in the short run prices will remain constant, but increase in the long run. Concentration in the retail sector will rise and opening hours will increase in two steps, immediately after deregulation and further over time. Finally, employment in the retail sector increases.Opening hours, retailing, deregulation

Transparency, entry, and productivity

This paper studies the relationship between transparency on the consumer side and productivity of firms. We show that more transparent markets are characterized by higher average productivity as firms with low productivity abstain from entering these markets. --Market Transparency,Firm Productivity,Salop Model,Heterogeneous Firms

Getting beer during commercials: adverse effects of Ad-Avoidance

This paper studies the impact of ad-avoidance behavior in media markets. We consider a situation where viewers can avoid advertisement messages. As the media market is a two-sided market, increased ad-avoidance reduces advertisers' value of placing an ad. We contrast two financing regimes, free-to-air and pay-TV. We find that increased avoidance opportunities decrease profits and entry in the free-to-air regime. In contrast, in the pay-TV regime, lower income from advertisements are compensated by higher subscription income leaving profits and the number of channels unaflected. Bypassing advertising messages affects welfare ambiguously. --Media Markets,Two-Sided Markets,Ad-avoidance

Regulating advertising in the presence of public service broadcasting

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 asymmetric regulation of ad levels on competition for viewers and advertisers in a duopoly framework where a public and a private broadcaster compete. If both broadcasters face the same advertising cap, regulation can be profit-increasing for both channels. If the public broadcaster is more strictly regulated, this may benefit the commercial rival if higher revenues in the advertising market outweigh the loss in viewership. --media markets,two-sided markets

A Note on the Excess Entry Theorem in Spatial Models with Elastic Demand

This paper revisits the excess entry theorem in spatial models à la Vickrey (1964) and Salop (1979) while relaxing the assumption of inelastic demand. Using a demand function with a constant demand elasticity, we show that the number of firms that enter a market decreases with the degree of demand elasticity.We find that the excess entry theorem does only hold when demand is sufficiently inelastic. Otherwise, there is insufficient entry. In the limiting case of unit elastic demand, the market is monopolized. We point out when and how a public policy can be desirable and broaden our results with a more general transportation cost function.Elastic demand, spatial models, excess entry theorem

Price-dependent demand in spatial models

This paper introduces price-dependent individual demand into the circular city model of product differentiation. We show that for any finite number of firms, a unique symmetric price equilibrium exists provided that demand functions are not too convex. As in the case of unit demand, the number of firms under free entry decreases in the fixed cost of entry while increases in the transportation cost of consumers. However, this number is no longer always in excess of the socially optimal level. Insufficient entry occurs when the fixed and transportation costs are high. --spatial models,price-dependent demand,horizontal product differentiation,demand elasticity,excess entry theorem

Indirect network effects with two Salop circles: the example of the music industry

This paper analyses the interdependency between the market for music recordings and concert tickets, assuming that there are positive indirect network effects both from the record market to ticket sales for live performances and vice versa. Using a model with two interrelated Salop circles we show that prices in both markets are corrected down- wards when compared to the standard Salop model. Furthermore, we show that the effects of file sharing on firms' profitability and on variety are ambiguous. File sharing can increase profits through increased concert ticket demand and thereby also lead to additional market entry and additional variety. --Music Industry,Indirect Network Effects,Salop Model,File Sharing

On file sharing with indirect Network effects between concert ticket sales and music recordings

This paper analyses the interdependency between the market for music recordings and concert tickets, assuming that there are positive indirect network effects both from the record market to ticket sales for live performances and vice versa. In a model with two interrelated Hotelling lines prices in both markets are corrected downwards when compared to the standard Hotelling model. Also, file sharing has ambiguous effects on firms' profitability. As file sharing can indirectly increase demand for live performances overall profits can either increase or decrease, depending on the strength of indirect network effects. Finally, file sharing may induce firms to switch from the traditional business model with two separate firms to an integrated business model where one agency markets both records and concerts (so-called 360 degree deals). --
