When calibrating a brand choice model cross-sectionally, a measure of brand loyalty is often introduced into the utility function to account for differences in utility across households and over time. One of the most widely used measures of brand loyalty, proposed by Guadagni and Little (1983),...

In field studies based on pre-test market and scanner data, researchers have found evidence of pioneering advantage in the form of an order-of-entry effect: a permanent share advantage that is greatest for the first brand to enter a market and smaller for each subsequently entering brand....

The authors develop and test a probabilistic model of purchase incidence and brand choice for frequently purchased consumer products. The model incorporates two ways of shopping in a category. Shoppers who have planned their purchasing (made a decision before entering the store) do not process...

This research models the dynamics of customer relationships using typical transaction data. Our proposed model permits not only capturing the dynamics of customer relationships, but also incorporating the effect of the sequence of customer-firm encounters on the dynamics of customer...

Recent work in marketing has drawn on behavioral decision theory to advance the notion that consumers evaluate attributes (and therefore choice alternatives) not only in absolute terms, but as from a reference point. The theory has important substantive and practical implications for the timing...

In some product categories, consumers appear to alternate among items in a consistent and purposeful, though not entirely deterministic, fashion. Such alternation occurs even in the absence of any apparent external influences on choice. To explain such balanced choice behavior, we present a...

In recent years, the supermarket industry has become increasingly competitive. One outcome has been the proliferation of a variety of pricing formats, and considerable debate among academics and practitioners about how these formats affect consumers' store choice behavior. This paper advances...

The objectives of urban traffic management are to make more efficient use of existing transportation resources and provide for the movement of people in an efficient manner through the development of low-cost short-range management strategies. Implementation of such strategies can provide for...

The National Science Foundation established the Decision and Management Sciences Program (DMS) in 1982. Healthy and growing, DMS is likely to affect OR/MS significantly, not only by providing funds for basic research, but also through its vision of a combined theoretical and empirical science of...

A manager tries to put together the various resources under his control into an activity that achieves his objectives. A model of his operation can assist him but probably will not unless it meets certain requirements. A model that is to be used by a manager should be simple, robust, easy to...
