This paper compares alternative procedures to mitigate the procyclicality of the new risk-sensitive bank capital regulation (Basel II). We estimate a model of the probabilities of default (PDs) of Spanish firms during the period 1987-2008, and use the estimated PDs to compute the corresponding...

Perceptron learning is discussed in the context of so-called scoring systems used for assessing creditworthiness as stipulated in the Basel II central banks capital accord of the G10-states. The solution of a related ranking problem using a generalised version of the pocket algorithm is...

In contrast to recent successful developments in macro monetary policies, the modelling, measurement and management of systemic financial stability has remained problematical. Indeed, the focus of most effort has been on improving individual, rather than systemic, bank risk management; the Basel...

The stability of International banking system has emerged as a key concern for regulators in rapidly changing global banking scenario. In order to strengthen the soundness and stability of banks, Basel Committee on Banking Supervision (BCBS) came out with a comprehensive, flexible and risk...

In this paper, we examine the relationship between banks’ approval for the internal ratings-based (IRB) approaches of Basel II and the ratio of risk-weighted over total assets. Analysing a panel of 115 banks from 21 OECD countries that were eventually approved for applying the IRB to their...

We present a simple model of an economy with heterogeneous banks that may be funded with uninsured deposits and equity capital. Capital serves to ameliorate a moral hazard problem in the choice of risk. There is a fixed aggregate supply of bank capital, so the cost of capital is endogenous. A...

Purpose – The IRB capital requirements of Basel II define the minimum level of capital that the bank has to retain to cover the current risks of its portfolio. The major risk that many banks are facing is credit risk and Basel II provides an approach to calculate its capital requirement. It is...

We consider capital allocation in a hierarchical corporate structure where stakeholders at two organizational levels (e.g., board members vs line managers) may have conflicting objectives, preferences, and beliefs about risk. Capital allocation is considered as the solution to an optimization...

Banking and finance are inherently pro-cyclical, a condition exacerbated by a combination of Basel II and mark-to-market accounting. But these latter measures have many advantages, so the need is to devise other counter-cyclical macroprudential policies. This fragility was further enhanced by a...
