The paper analyses the problem of evaluating a guarantee contract against default risk in which the guarantor party is defaultable and the default risks of the guarantor and of the borrower are correlated. This problem has several relevant applications within the present sovereign risk crisis....

I provide a complete characterization of equilibrium with risk of default in sequential economies under uncertainty. Default induces permanent exclusion from financial markets and not-too-tight solvency constraints prevent debt repudiation at equilibrium. The method of analysis relies on a...

This paper investigates the price for contingent claims in a dual expected utility theory framework, the dual price, considering arbitrage-free nancial markets. A pricing formula is obtained for contingent claims written on n underlying assets following general Itô processes and without any...

In this paper, we consider economies with (possibly endogenous) solvency constraints under uncertainty. Constrained ine±ciency corresponds to a feasible redistribution yielding a welfare improvement beginning from ev- ery contingency reached by the economy. A sort of Cass Criterion (Cass [10])...

In recent years both practitioners and academics have realised that traditional discounted cash flow models erroneously consider the option value embedded in firms. Hence equity and debt valuation methodologies based on option theory have recently become quite popular. Such methodologies take...

This paper investigates the price for contingent claims in a dual expected utility theory framework, the dual price, considering complete arbitrage-free nancial markets. In this framework this dual price is obtained, for the rst time in the literature, without any comonotonicity hypothesis and...

This paper is concerned with the valuation of European continuous-installment options where the aim is to determine the initial premium given a constant installment payment plan. The distinctive feature of this pricing problem is the determination, along with the initial premium, of an optimal...

In this paper we present an integral equation approach for the valuation of European-style installment derivatives when the premium payments, made continuously throughout the contract’s life, are assumed to be a function of the asset price and time variables. The contribution of this study is...

We prove indeterminacy of competitive equilibrium in sequential economies, where limited commitment requires the endogenous determination of solvency constraints preventing debt repudiation (Alvarez and Jermann [3]). In particular, we show that, for any arbitrary value of social welfare in...

In this paper we present an integral equation approach for the valuation of American-style installment derivatives when the premium payments, made continuously throughout the contract’s life, are assumed to be a function of the asset price and time. The contribution of this study is...
