This is the first paper that examines economies of scale in stock exchanges. The data employed in the study include cost and output statistics for 37 stock exchanges in four continents around the world for the year 1997. I estimate two traditional cost functions and find that ray (overall) scale...

This paper investigates the existence and extent of economies of scale and scope among stock exchanges. Evidence from 38 exchanges in 32 countries and 4 continents around the world for the years 1989-1998 indicates the existence of significant economies of scale and scope. The degree of such...

In recent years, demutualized stock exchanges have increasingly engaged in M&A and alliance activities. To shed light on this topic, we investigate short-run share price responses to the formation of 110 stock exchange M&As and alliances in the period 2000–2008. Our findings show that the...

Using lenders becoming members of the Task Force on Climate-Related Financial Disclosures (TCFD) as a plausible exogeneous shock, we examine whether and how lenders’ commitment to transparent climate-related disclosures affects borrower firms’ environmental performance. We find that client...

Using a spatial competition model of retail payment networks, this paper discusses the likely economic consequences associated with the formation of the Single Euro Payments Area (SEPA). The model considers an expansion of positive network externalities on the demand side and adjustment cost on...

We study the long standing issue of whether markets can supply banks with sufficient liquidity or whether markets should be complemented with a lender of last resort (LOLR). For this purpose, we develop an extended version of the recent model of Holmstrouml;m and Tirole (1998) on the supply of...

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 tests the hypothesis that the more fragile a banking system is, the more likely it is to experience problems when an unexpected shock hits. The empirical framework where this test is conducted is a reduced form model, where macroeconomic factors explain banks' loan losses. The...

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...

Basel II framework requires banks to conduct stress tests on their potential future minimum capital requirements and consider 'at least the effect of mild recession scenarios'. We propose a stress testing framework for minimum capital requirements in which banks' corporate credit risks are...
