The Bank of International Settlement document (BIS 2004) opened the door to the possibility of using, subject to validation by the individual national supervisory authorities, systems of internal rating of credit risk developed by the banks when they satisfy certain criteria. Specifically, the...

We re-analyze endogenous sample selection in the context of customer scoring, targeting, and influencing decisions. Scoring relies on ordered lists of probabilities that customers act in a way that contributes revenues, e.g. purchase something from the firm. Targeting identifies constrained sets...

Counterparty risk is an important determinant of corporate credit spreads. However, there are only a few techniques available to isolate it from other factors. In this paper we describe a model of financial networks that is suitable for the construction of proxies for counterparty risk. Using...

The objective of this research is to check if social orientation of citizens firms is undertaking an instrumental approach or intrinsic commitment. Based on a sample composed by most admired firms, we examine - in cross sectional studies and industrial analysis - financial, strategy and social...

In this paper, we empirically analyze the effect of the credit crisis of 2008 by adopting coexceedance as a contagion measure. We assess the effect of news of governmental intervention and the collapse of firms during the period from 2007 to 2009 on the coexceedance. Our approach involves...

I develop methods that produce consistent estimates of the Vasicek-Basel IRB (VAIRB) credit risk model parameters. I apply these methods to Moody's data on corporate defaults over the period 1920–2008 and assess the model fit and construct hypothesis tests using bootstrap methods. The results...

The present paper proposes a model for the persistence of abnormal returns both at firm and industry levels, when longitudinal data for the profits of firms classiffied as industries are available. The model produces a two-way variance decomposition of abnormal returns: (a) at firm versus...

Instrumental variable estimation requires untestable exclusion restrictions. With policy effects on individual outcomes, there is typically a time interval between the moment the agent realizes that he may be exposed to the policy and the actual exposure or the announcement of the actual...

This study extends Seck's (1996) approach to investigate the degree of substitutability between equity real estate investment trusts (EREITs) and mortgage real estate investment trusts (MREITs). The variance ratio test and the variance decomposition of forecast errors yield results indicating...

This study analyses the performance of real estate mutual funds for 1993 through 2001 period. The results indicate that real estate mutual funds do not provide positive abnormal performance on average. Fund performance to a large extent is determined by the performance of the real estate sector...
