Weighted least squares (WLS) analysis of categorical data is used to provide a general framework for the analysis of brand switching data. As in an earlier approach described by Urban, Johnson, and Hauser (Urban, G. L., P. L. Johnson, J. R. Hauser. 1984. Testing competitive market structures....

This paper presents a new multidimensional scaling (MDS) methodology which operationalizes the Krumhansl (1978) distance-density model for the analysis of asymmetric proximity data. In Krumhansl's conceptualization, the symmetric Euclidean interbrand distances typically associated with the...

Many empirical studies in marketing and economics have estimated brand price elasticities for specific products in markets. Their results indicate that price elasticities seem to differ across brands, product categories, retail outlets, and regions. However, there has been very little research...

A one-to-one map between a specific demand structure and a restricted cross-elasticity matrix is developed and tested using a random utility model. The resulting demand structure can be used to evaluate a firm's ability to differentiate its products, and can help determine if demand is...

This paper shows that the analysis of Liu et al. (2004) contains a substantive error—the asserted pure-strategy Nash equilibrium leading to their Theorems 1 and 2 is really not an equilibrium. We show that in their model, either pure-strategy Nash equilibria do not exist or, unlike their...

A structured market for a product category is a pair (, ) consisting of a set of consumers who have the same decision tree, , which reflects the process by which the consumers in evaluate product features when making choices. Using a nested logit approach: (1) we present methods to test for the...

This paper examines how the nature of the technological regime governing innovative activities and the structure of demand interact in determining market structure, with specific reference to the pharmaceutical industry. The key question concerns the observation that - despite high degrees of...

A recent paper by Novak and Stangor (, Winter 1987) on testing competitive market structures involves testing a two-sided hypothesis to determine the nature of the competitive market structure. In this paper we provide an improvement to the Novak and Stangor procedure by considering a one-sided...

This paper examines the two externalities that a country's environmental regulation imposes on other country's welfare: an environmental externality, due to transboundary pollution, and a competitive advantage externality, as regulations affect domestic firms' abatement costs, which impact the...

The steel industry has been protected by a wide variety of trade policies, both tariff- and quota-based, over the past decades. This extensive heterogeneity in trade protection provides the opportunity to examine the well-established theoretical literature predicting nonequivalent effects of...
