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...

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...

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...

Central securities depositories (CSDs) have opened mutual links, but most of them are seldom used. Why are idle links established? By allowing a foreign CSD to offer services through the link the domestic CSD invites competition. The domestic CSD can determine the cost efficiency of the rival by...

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...

This paper presents a model depicting cross-border payment systems as a mixed oligopoly. A private net settlement system that maximises profit competes with the central banks’ gross settlement system that maximises welfare. It may be optimal for the central bank system to encourage increased...

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...
