It is commonplace to link neoclassical economics to 18th- or 19th-century physics and its notion of equilibrium, of a pendulum once disturbed eventually coming to rest. Likewise, an economy subjected to an exogenous shock seeks equilibrium through the stabilizing market forces unleashed by the...

This paper investigates the United States dollar's role as the international currency of choice as a key contributing factor in critical global developments that led to the crisis of 2007-09, and considers the future role of the dollar as the global economy emerges from that crisis. It is argued...

Yet another rescue plan for the European Monetary Union (EMU) is making its way through central Europe, but no one is foolish enough to believe that it will be enough. Greece's finance minister reportedly said that his nation cannot continue to service its debt, and hinted that a 50 percent...

We introduce a framework for analyzing the interplay between credit risk and collateralmarket risk on loan pricing. To do this, we decompose any loan into an unsecured and asecured part. Further we explicitly consider the recovery process. The framework allows usto develop semi-analytical...

We examine the quantification of operational risk for banks. We adopt a financial-economics approach and interpret operational risk management as a means of optimizing the profitability of an institution along its value chain. We start by defining operational risk and then propose a...

In this paper, we characterize explicitly the first derivative of the Value at Risk and the Expected Shortfall with respect to portfolio allocation when netting between positions exists. As a particular case, we examine a simple Gaussian example in order to illustrate the impact of netting...

Like many financial contracts, derivatives are subject to default risk. A very popular mechanism in derivatives markets to mitigate the risk of non-performance on contracts is margining. By attaching collateral to a contract, margining supposedly reduces default risk. The broader impacts of the...

Economic cycles are the key credit portfolio risk driver and they are autocorrelated over time. We then show that it is economically meaningful to define risk for credit portfolios in a multi period setup. Since one period expected shortfall fails to measure risk adequately in a multi period...

We introduce an adaptive importance sampling method for the loss distribution of credit portfolios based on the Robbins-Monro stochastic approximation procedure. After presenting the subtle construction of the algorithm, we apply our adaptive scheme for calculating the risk figures of a typical...

In this paper, we study the economic benets from using credit scoring models. We contribute to the literature by relating the discriminatory power of a credit scoring model to the optimal credit decision. Given the Receiver Operating Characteristic (ROC) curve of the credit scoring model, we...
