This paper derives fundemental arbitrage pricing results in finite dimensions in a simple unified framework using Tucker's theorem of the alternative. Frictionless results plus those with dividends, periodic interest payments, transaction costs, different interest rates for lending and...

Due to their underlying assumptions, the standard concepts of risk aversion and preference for the present are generally defined separately and represented by scalar measures, and this implies many shortcomings. More specifically, if measured by a scalar, the risk aversion remains unchanged,...

Credit Default Swaps (CDS) are in the process of becoming, liquid and extremelyinformative instruments of default risk. Yet, default swap market has severalnovel aspects that have not received much attention. In this paper we studyan aspect of CDS´s that relates to the prediction of financial...

In this paper, we investigate how investors who face both equity risk andcredit risk would optimally allocate their financial wealth in a dynamic continuous-time setup. We model credit risk through the defaultable zero-coupon bond and solve the dynamics of its price after pricing it. Using...

In this paper we develop a structural model of counterparty risk . In particular we provide closed form formulae for the price of risky debt and equity, which depend up on the lending/borrowing relationships in the economy. Our model applies to completely general lender/borrower relationships,...

This paper presents a utility-based approach to value the borrower optimal behavior in presence of credit risk. The paper solves for the dynamic portfolio choices of a borrower. We thereby show that the presence of debt leads to a substantial modification in the borrower's behavior across states...

This paper shows that a stock market is evolutionary stable if andonly if stocks are evaluated by expected relative dividends. Any othermarket can be invaded by portfolio rules that will gain market wealthand hence change the valuation. In the model the valuation of assetsis given by the wealth...

We develop intuitive expressions for the spread between a forwardcontract and a similar futures contract taking into account the pos-sibility of counterparty default. We evaluate these expressions nu-merically and show that the forward-futures spread is significant forrealistic parameter...

n this paper we analyse recovery rates on defaulted bonds using the Standard and Poors / PMD database for the years 1981-1999. Due to the specific nature of the data (observations lie within 0 and 1), we must rely on nonstandard econometric techniques. The recovery rate density is estimated...

Most derivative contracts are traded over-the-counter, i.e., bilaterally between two counterparties. Recently, clearing services have become available that allow to transfer over-the-counter derivatives to a central counterparty (clearing house). We develop a framework to determine the effects...
