We study risk and return characteristics of CDOs using the market standard models. We find that fair spreads on CDO tranches are much higher than fair spreads on similarly-rated corporate bonds. Our results imply that credit ratings are not sufficient for pricing, which is surprising given their...

This paper uses the market-standard Gaussian copula model to show that fair spreads on CDO tranches are much higher than fair spreads on similarly-rated corporate bonds. It implies that credit ratings are not sufficient for pricing, which is surprising given their central role in structured...

Previous risk management in the venture capital industry has focused mainly on qualitative risk management, such as team selection and due diligence. As investment volume has increased during the past decade, and as venture capital becomes more important as an asset class for institutional...

Attribution of economic joint effects is achieved with a random order model of their relative importance. Random order consistency and elementary axioms uniquely identify linear and proportional marginal attribution. These are the Shapley (1953) and proportional (Feldman (1999, 2002) and Ortmann...

Lenders use rating and scoring models to rank credit applicants on their expected performance. The models and approaches are numerous. We explore the possibility that estimates generated by models developed with data drawn solely from extended loans are less valuable than they should be because...

We adapt a metric of Kandel and Stambaugh (1995) to evaluate linear asset pricing models. The quot;KS-ratioquot; criterion rates a model's usefulness based on the mean portfolio return a mean-variance decision maker obtains for any variance choice by using the model for optimal portfolio...

This study constructs and evaluates a risk model for the venture capital industry in which the CreditRisk+ model is adjusted to calculate loss distributions for venture capital portfolios. A forward entry regression with macroeconomic factors as independent variables is used as the procedure to...

Expected Shortfall (ES) has been proposed as an alternative, almost coherent, risk measure to Value-at-Risk (VaR), as it considers expected loss beyond VaR. In this paper, we compare the performance of different models in estimating VaR and ES using historical data. Daily returns of popular...

This paper introduces impulse response analysis for nonlinear processes based on the concept of nonlinear innovation. Our approach borrows from the traditional linear impulse response analysis in that we consider shocks to innovations of a process. It also extends the methods of nonlinear...

The treatment of this article renders closed-form density approximation feasible for univariate continuous-time models. Implementation methodology depends directly on the parametric-form of the drift and the diffusion of the primitive process and not on its transformation to a unit-variance...
