We build a simple model to study service fee competition between an incumbent and an independent ATM deployer, and its optimal regulation. We use the model to analyze an actual regulation of such a market by competition authorities in Finland. We find that socially optimal first-best fees would...

The 5th joint SUERF/Bank of Finland joint conference was held in Helsinki on 13 June 2013. The general theme of the conference was to focus on the regulatory reforms after the global financial crisis and, in particular, how structural reforms of banking ("Volcker, Vickers and Liikanen") could...

This paper tests for the existence of market power in banking, using data on demand deposit rates of households and corresponding market rates in five euro area countries. An implicit measure for market power is based on a partial adjustment model that also allows for an asymmetric response of...

This paper tests market power in the banking industry. Price-cost margins predicted by different oligopoly models are calculated using discrete-choice demand estimates of own-price and cross-price elasticities. These predicted price-cost margins are then compared with price-cost margins computed...

In this paper a game theoretic duopoly model is developed to analyse the development of an interbank payment system. There are two competing banks in the model, and payment services offered to the public are among their main products. The customer of the larger bank uses mainly intrabank payment...

We study the adverse selection problem in imperfectly competitive credit markets and illustrate the circumstances where a separating equilibrium emerges, even without collateral. The borrowers are heterogeneous in their preferences concerning the banks. Separation obtains in market segments...

Cards and cash are competing payment instruments at point-of-sale. The twosided market platform theory, based on general benefit assumptions, supports the use of multilateral interchange fees for card payments as a means of promoting the use of cards. However, analysis of the issue from the...

This paper presents a duopoly model of the securities settlement industry. Because pooling a large amount of payments can help in using liquidity efficiently, issuers prefer systems where a large number of securities are issued. If the central securities depositories establish a mutual link that...

Persistent shifts in equilibria are likely to arise in oligopolistic markets and may be detrimental to the measurement of conduct, related markups and intensity of competition. We develop a cointegrated VAR (vector autoregression) based approach to detect long-run changes in conduct when data...

This paper proposes and tests an explanation as to why rational managers seeking to maximize shareholder value can pursue value-decreasing mergers. It can be optimal to overpay for a target firm and decrease shareholder value if the loss is less than in an alternative where the merger is...
