Most traditional studies of R&D do not consider that the use of leverage to finance R&D may affect total R&D expenditures in a patent race. We show that debt acts as a commitment to a smaller amount of total R&D spending (debt+equity) than would occur if firms were entirely equity financed. A commitment to lower R&D expenditure can be strategically beneficial; under a flow-cost model, debt indu...

Through a cost-minimizing approach, this paper derives four joint indicators to assess the ef…ciency of the mix of sovereign debt currencies between the countries belonging to the European Monetary Union (EMU). This theoretical insight enables us to explain why and how the introduction of the euro and the adoption of a common monetary policy may have led to signi…cant changes in debt structure ...

: Collateralized debt obligatons (CDOs) constitute an important subclass of asset backed securities. The evaluation of CDOs relies on mathematical modeling and on simulation as well as analytic and semi-analytic approaches, depending on the underlying asset pool and the cash flow structure of the transaction. This paper is an introductory survey on CDO modeling. It starts with a ‘mini course’ o...

I conduct an empirical investigation into the pricing of subprime asset-backed collateralized debt obligations (CDOs) and their contagion effects on other markets. Using data for the ABX subprime indexes, I find strong evidence of contagion in the financial markets. The results support the hypothesis that financial contagion was propagated primarily through liquidity and risk-premium channels, ...

In recent years the financial world has seen an increasing demand for faster risk simulations, driven by increasing contract complexity and client portfolio growth. Traditionally many financial models employ Monte-Carlo simulation, which can take excessively long to compute in software. Hence, commonly a hardware accelerator is sought out. This thesis focuses on accelerating structured financia...

This paper uses distortions of the bivariate Gaussian copula to produce a heavy tail for expected portfolio loss distribution in the context of synthetic Collateralized Debt Obligations (CDOs). We demonstrate that when the distorted copulas are used within the JP Morgan CDO pricing formula, as an example, we can simulate quite realistic tranche prices. Furthermore, we need only one dependence p...

Collateralized Debt Obligations (CDOs) are sophisticated financial products that offer a range of investments, known as tranches, at varying risk levels backed by a collateral pool typically consisting of corporate debt (bonds, loans, default swaps, etc.). The analysis of the risk-return properties of CDO tranches is complicated by the highly nonlinear and time dependent relationship between th...

This paper provides a general framework for doubly stochastic term structure models for portfolio of credits, such as collateralized debt obligations (CDOs). We introduce the defaultable (T, x)-bonds, which pay one if the aggregated loss process in the underlying pool of the CDO has not exceeded x at maturity T , and zero else. Necessary and sufficient conditions on the stochastic term structur...

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 ...
