Practically all industrialized economies restrict the length of time that credit bureaus can retain borrowers’ negative credit information. There is, however, a large variation in the permitted retention times across countries. By exploiting a quasi-experimental variation in this retention...

Swedish law mandates the removal of information about past credit arrears from the individuals’ credit reports after three years. By exploiting a quasi-experimental variation in retention times caused by a change in the credit bureau’s timing of arrear removal, we are able to examine the...

We study the specific corporate governance problems of central banks in their complex role of inflation guardians, bankers' banks, financial industry regulators/supervisors and, in some cases, competition authorities and deposit insurance agencies. We review the current institutional...

In this paper we empirically study interactions between real activity and the financial stance. Using aggregate data we examine a number of candidate measures of the financial stance of the economy. We find strong evidence for substantial spillover effects on aggregate activity from our...

The new Basel II regulation contains a number of new regulatory features. Most importantly, internal ratings will be given a central role in the evaluation of bank loans' riskiness. Another novelty is that retail credit and SME loans will receive a special treatment in recognition of the fact...

A drawback of available portfolio credit risk models is that they fail to allow for default risk dependency across loans other than through common risk factors. Thereby, these models ignore that close ties can exist between companies due to legal, financial and business relations. In this paper,...

Despite a surge in the research efforts put into modelling credit risk during the past decade, few studies have incorporated the impact that macroeconomic conditions have on business defaults. In this paper, we estimate a duration model to explain the survival time to default for borrowers in...

To evaluate loan applicants, banks increasingly use credit scoring models. The objective of such models typically is to minimize default rates or the number of incorrectly classified loans. Thereby they fail to take into account that loans are multiperiod contracts for which reason it is...

The Internal Ratings Based (IRB) approach for capital determination is one of the cornerstones in the proposed revision of the Basel Committee rules for bank regulation. We evaluate the IRB approach using historical business loan portfolio data from a major Swedish bank for the period 1994 to...

The Internal Ratings Based (IRB) approach for determining banks' capital adequacy is one of the cornerstones of the Basel Committee's proposed revision of the Basel Accord for banking regulation. This article presents the ideas behind the IRB approach and its fundamental features, and discusses...
