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 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...

Consider a competitive bank whose illiquid asset portfolio is funded by short-term debt that has to be refinanced before the asset matures. We show that in this setting maximal transparency is not socially optimal, and that the existence of social externalities of bank failures further lowers...

The innovation activities of companies has long been a topic of interest in economics. Game theory models of oligopoly have since the start of the 1980s played a central role in the economics of innovation. In this study three game theory duopoly models are presented and each is used to analyse...

We consider the impact of mandatory information disclosure on bank safety in a spatial model of banking competition in which a bank’s probability of success depends on the quality of its risk measurement and management systems. Under Basel II capital requirements, this quality is either fully...

We investigate the impact of bank competition on the use of collateral in loan contracts. We develop a theoretical model incorporating information asymmetries in a spatial competition framework where banks choose between screening the borrower and asking for collateral. We show that presence of...

This paper studies relationship lending in a framework where the cost of switching banks measures the degree of banking competition. The relationship lender’s (insider bank’s) informational advantage creates a lock-in effect, which is at its height when the switching cost is infinitesimal....

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...
