We propose a maximum likelihood framework for estimating finite mixtures of multivariate regression and simultaneous equation models with multiple endogenous variables. The proposed “semi‐parametric” approach posits that the sample of endogenous observations arises from a finite mixture of...

Choice-based conjoint analysis has increased in popularity in recent years among marketing practitioners. The typical practice is to estimate choice-based conjoint models at the aggregate level, given insufficient data for individual-level estimation of part-worths. We discuss a method for...

In this paper an approach is developed that accommodates heterogeneity in Poisson regression models for count data. The model developed assumes that heterogeneity arises from a distribution of both the intercept and the coefficients of the explanatory variables. We assume that the mixing...

Various research areas face the methodological problems presented by nonnegative integer count data drawn from heterogeneous populations. We present a disaggregate negative binomial regression procedure for analysis of count data observed for a heterogeneous sample of cross-sections, possibly...

The authors propose a methodology for determining the segment-level impact of explanatory variables on multiple criterion measures obtained on a constant-sum scale. These explanatory variables could characterize different product, situation, or person related conditions that either occur...

The authors propose a new methodology for deriving hierarchical product-market structures from disaggregate purchase data. A hierarchical product-market tree is estimated from scanner panel purchase data in a maximum likelihood framework. The derived product-market representation portrays both...

The Ricardian principle of comparative advantage has long been at the foundation of a wide range of economic models. In the new Internetworked economy where co-creational experiences of value is rapidly gaining momentum, the vision of this principle has weakened. We provide a framework to align...

Economics has traditionally split consumers from producers by assigning them fixed roles. In the Internetworked economy as it is becoming, this is no longer true as value is increasingly jointly created among individuals, as a function of their co-creation experiences. We construct a framework...
