Marketing Strategy For Unusual Brand Differentiation: Trivial Attribute Effect, M. Deniz Dalman, Junhong Min
College of Business Publications
This research investigates that brand differentiation creating superior values can be achieved not only by adding meaningful attributes but also meaningless attributes, which is called “trivial attribute effect.” Two studies provided empirical evidences as following; first, trivial attribute effect creates a strong brand differentiation even after subjects realize that trivial attribute has no value. Second, trivial attribute effect is more pronounced in hedonic service category compared to the utilitarian category. Last, the amount of willingness to pay is higher when trivial attribute is presented and evaluated in joint evaluation mode than separate evaluation mode. Finally, we conclude with discussion and …

Credit Risk Models: An Analysis Of Default Correlation, Howard Qi, Yan Alice Xie, Sheen Liu
College of Business Publications
This paper examines one of the major problems in credit risk models widely used in the financial industry to forecast future defaults and bankruptcies. We find that even after proper calibration, a representative credit risk model can severely underestimate default correlation. We further find that a likely reason for the underestimation of default correlation is the problematic common practice in the financial industry of using observable equity correlation as a proxy for unobservable asset correlation when the model is applied to predict default correlation. However, our results show that this proxy in common practice is not valid.

Multiple regression models continue to be widely used in marketing. Within the regression framework, researchers have to grapple with and resolve several contentious issues. For example, multicollinearity, nonsimultaneous estimation of parameters, inherent measurement error in independent variables, absence of overall goodness of fit indices, and lack of compelling guidelines for adding and deleting model variables are some common estimation problems associated with this method. In the absence of universally acceptable guidelines, researchers often use judgment calls to deal with these issues. Such ad-hoc approaches, in turn, compromise the potential usefulness of multiple regression models. In this paper, we position path …
