Traditional models of consumer choice assume consumers are aware of all products for sale. This assumption is questionable, especially when applied to markets characterized by a high degree of change, such as the personal computer (PC) industry. I present an empirical discrete-choice model of...

This paper specifies and estimates a dynamic model of consumer preferences for new durable goods with persistent heterogeneous consumer tastes, rational expectations about future products and repeat purchases over time. Most new consumer durable goods, particularly consumer electronics, are...

Many durable goods, particularly in the high technology sector of the economy, experience rapid quality improvement. As a result, replacement is typically due to obsolescence rather than breakdown, and replacement cycles are relatively short. When these goods are vertically differentiated,...

The static differentiated product demand model when applied to products with rapid product turnover and declining prices, yields implausible results. One response is to explicitly model the inter-temporal choices of consumers but computational demands require restrictive assumptions on consumer...

Although the fast advancing smartphone technology makes connectivity possible for shoppers to reach almost any online shopping mall, it does not ensure success in the development of an online shopping platform for smartphone technology. This research studied the buyers' perception about mobile...

Many features of interest can be observed from metrics of user navigation, of site structure and of paths followed through the site. These metrics can be used for recognizing and predicting usability matters. This papers discusses models and techniques needed, and how they can be used for...

This paper computes a quality adjusted price index for the personal computer CPU from 1996 to 2000. The index is based on the pure characteristics demand model. I first compute the quality adjusted price index for the whole market, and show that it is very comparable with the hedonic price index...

In this article, we provide a novel measure of product differentiation by observing consumer search behavior directly. We track individual consumers in a price search engine and generate a measure of distance in product space, based on goods surveyed conjointly within individual search episodes....

When there are many attributes, experiments with Conjoint Analysis include problems of information overload that affect the validity of such experiments. The impact of these problems can be avoided or reduced by using Hierarchical Information Integration (HII). The present work aims to...

Purpose: One of the main questions about the future of print and electronic books is whether the second will replace the first. Although the electronic book was first introduced to the public in 1971, the trend of reading e-books did not gain popularity until the previous decade. The recent...
