This paper considers the modelling of collateralized debt obligations (CDOs). We propose a top-down model via forward rates generalizing Filipović, Overbeck and Schmidt (2009) to the case where the forward rates are driven by a finite dimensional Lévy process. The contribution of this work is twofold: we provide conditions for absence of arbitrage in this generalized framework. Furthermore, we ...

This paper considers the pricing and hedging of collateralized debt obligations (CDOs). CDOs are complex derivatives on a pool of credits which we choose to analyse in the top down model proposed in Filipović et al. [4]. We reflect on the implied forward rates and bring them in connection with the top-down framework in Lipton and Shelton [8] and Schönbucher [11]. Moreover, we derive variance-mi...

One of the most significant developments in international credit markets in recent years has been the trade in Collateralized Debt Obligations (CDO), which has enabled financial institutions to repackage the credit risk of an asset portfolio into tranches to be transferred to investors. The present paper evaluates the credit risk of such a portfolio and the related tranches by applying two prom...

During the past decade, a structured financial product called “Collateralized Debt Obligation (CDO)” has been drawing much attention of researchers and practitioners, and is now traded with growing liquidity. However, the approach for CDO pricing has been rather limited in the literature, largely because it is necessary to evaluate the time dependent distribution of the underlying cumulative lo...

any of the myriad problems in the u.s. mortgage market could have been contained, but together they caused a crisis that spread across the globe T HE causes of the crisis in subprime mortgages have become clear. They started with poor underwriting practices, which became legion. But damage was propagated at each stage of the complicated process in which a risky home loan was originated, then be...

Asset-backed securitization (ABS) has become a viable and increasingly attractive risk management and refinancing method either as a standalone form of structured finance or as securitized debt in Collateralized Debt Obligations (CDO). However, the absence of industry standardization has prevented rising investment demand from translating into market liquidity comparable to traditional fixed in...

Correlation-dependent derivatives, such as Asset-Backed Securities (ABS) and Collateralized Debt Obligations (CDO), have grown rapidly. Factor models in the conditional independence framework are widely used in practice to capture the correlated default events of the underlying obligors. An essential part of these models is the accurate and efficient evaluation of the expected loss of the speci...

This study investigates the effect of the external debt burden on economic growth and development of Nigeria .It adopted regression analysis of OLS on secondary data sourced from CBN, Economical and Financial review, Business times, Financial Standard and relevant publication from Nigeria on variable like National Income, Debt Service Payment, External Reserves, Interest rate among others. The ...

This paper analyses whether sovereign default episodes can be seen as contingencies of optimal international lending contracts. The model considers a small open economy with capital accumulation and without commitment to repay debt. Taking first order approximations of Bellman equations, I derive analytical expressions for the equilibrium level of debt and the optimal debt contract. In this env...
