Experimental conjoint choice analysis is among the most frequently used methods for measuring and analyzing consumer preferences. The data from such experiments have been typically analyzed with the Multinomial Logit (MNL) model. However, there are several problems associated with the standard...

We develop a general class of factor-analytic models for the analysis of multivariate (truncated) count data. Dependencies in multivariate counts are of interest in many applications, but few approaches have been proposed for their analysis. Our model class allows for a variety of distributions...

With recent advances in information technology, most companies are amassing extensive customer databases. The wealth of information in these databases can be useful in identifying those customers most likely to purchase a new product and in predicting when this adoption may take place. This can...

This paper introduces a general, formal treatment of dynamic constraints, i.e., constraints on the state changes that are allowed in a given state space. Such dynamic constraints can be seen as representations of "real world" constraints in a managerial context. The notions of transition,...

A variant of Banker and Morey's (Banker, R. D., R. C. Morey. 1986. The use of categorical variables in data envelopment analysis. Management Sci. 32(12, December) 1613--1627.) DEA model for controllable ordinal outputs. As opposed to the original model, this version allows the comparison of a...

In a situation where several hundred new music albums are released each month, producing sales forecasts in a reliable and consistent manner is a rather difficult and cumbersome task. The purpose of this study is to obtain sales forecasts for a new album before it is introduced. We develop a...

In this study, we attempt to understand how household budget allocations across various expenditure categories change when the economy is in recession or expansion. The common assumption is that a household’s tastes would not change as a function of economic conditions and therefore any...

Consumer heterogeneity is fundamental to the marketing concept, providing the basis for market segmentation, targeting and positioning, as well as micro-marketing. Substantial effort has already been devoted to incorporate heterogeneity in brand choice models. However, most of the research in...
