Twenty‐five years of the Taffler z‐score model: Does it really have predictive ability?

Although copious statistical failure prediction models are described in the literature, appropriate tests of whether such methodologies really work in practice are lacking. Validation exercises typically use small samples of non‐failed firms and are not true tests of ex ante predictive ability, the key issue of relevance to model users. This paper provides the operating characteristics of the well‐known Taffler (1983) UK‐based z‐score model for the first time and evaluates its performance over the 25‐year period since it was originally developed. The model is shown to have clear predictive ability over this extended time period and dominates more naïve prediction approaches. This study also illustrates the economic value to a bank of using such methodologies for default risk assessment purposes. Prima facie, such results also demonstrate the predictive ability of the published accounting numbers and associated financial ratios used in the z‐score model calculation.     

The Effect of Mortgage Rate Buydowns on Housing Prices:

The model developed in this paper analyzes the effect of builder-financed FHA-VA mortgage subsidies or buydowns on the price of housing. Hedonic pricing equations are estimated for a locationally and qualitatively uniform sample of new tract development homes. The explanatory variables are vectors of physical and financial characteristics. The latter include a continuous variable for discount points paid by builders which is indicative of the magnitude of prepaid finance charges. The results indicate that a substantial portion of mortgage subsidy costs are shifted to buyers in the form of inflated housing prices.     

Migration of professional manpower to the United States

The results of an investigation of the immigration of professionals to the United States are presented. The data concern a sample of professionals from 17 developing and developed countries who were immigrants in 1969. Both direct and indirect immigration are considered, and special attention is paid to the constraints on professional immigration and the adjustment of status imposed by immigration policies. The results suggest that the relative wage rate is more strongly related to the brain drain than is relative income and that more restrictive policies concerning labor certification would probably prove effective in reducing the student brain drain in the short term.     

What Really Leads to Partner Relationship Management? A Review of Literature

This research article aims at providing a comprehensive overview of the Partner Relationship Management (PRM) domain through an exhaustive literature survey. Current scenario, definitions/perspectives, breakdown of studies by nation, PRM as a software application, the need for PRM, the process of developing partner relationships, and major models, along with major defining constructs and other major insights, have been summarized in the area of partner relationship management using content analysis. The focus is on bridging the gap in the existing academic literature by providing a comprehensive compilation of partner relationship management literature inclusive of B2B and B2C scenarios for future researchers. A list of select premier academic databases has been used to identify the relevant research papers in the domain. This article will help in reducing the time and efforts of researchers by quickly providing a comprehensive view of the PRM literature.
