Recently there has been some interest in the credit risk literature in models which involve stopping times related to excursions. The classical Black-Scholes-Merton-Cox approach postulates that default may occur, either at or before maturity, when the firm's value process falls below a critical...

We propose and examine a simple model for credit migration and spread curves of a single firm both under the real-world and the risk-neutral measure. This model is a hybrid of a structural and a reduced-form model. Default is triggered either by successive downgradings of the firm or an...

We propose a structural credit risk model for consumer lending using option theory and the concept of the value of the consumer’s reputation. Using Brazilian empirical data and a credit bureau score as proxy for creditworthiness we compare a number of alternative models before suggesting one...

This paper tests empirically the performance of three structural models of corporate bond pricing, namely Merton (1974), Leland (1994) and Fan and Sundaresan (2000). While the first two models overestimate bond prices, the Fan and Sundaresan model reveals an extremely good performance. When...

An exogenous impact function is defined as the derivative of a structural function with respect to an endogenous variable, other variables, including unobservable variables held fixed. Unobservable variables are fixed at specific quantiles of their marginal distributions. Exogenous impact...

This essay will consider the relevance of the social sciences - especially economics - to the foundations of sustainable development. Looming environmental crises have served as a prime motivating force for reevaluating fundamental principles. In particular, the concept of sustainability,...

Productive consumption enables the satisfaction of current needs and, at the same time, increases the productive potential of labour. Theoretical as well as empirical evidence suggests that productive consumption is primarily relevant to low-income countries. From the perspective of growth...

By the end of 1999 HIV/AIDS was present in at least 200 countries and approximately 34.3 million people were living with the disease, 5.3 million of whom had been infected in that year alone (WHO 2000). Approximately 21.8 million persons had died from AIDS by 2000 and countries where life...

We analyze the intergenerational income mobility of Canadians born to immigrants using the 2001 Census. A detailed portrait of the Canadian population is offered as are estimates of the degree of generational mobility among the children of immigrants from 70 countries. The degree of persistence...
