Consumer Behavior

We address multi-item inventory systems with random and seasonally fluctuating, and possibly correlated, demands. The items are produced in two stages, each with its own lead-time; in the first stage a common intermediate product is manufactured. The production volumes in the first stage are bounded by given capacity liits. We develop an accurate lower bound and close-to-optimal heuristic strategies of simple structure. The gap between them, evaluated in an extensive numerical study, is on average only 0.45%.

To understand really new products, consumers face the challenge of constructing new knowledge structures rather simply changing existing ones. Recent research in categorization suggests that one strategy for creating representations for these new products is to use information already contained in familiar product categories. While knowledge from multiple existing categories may be relevant, little research has examined how (and if) consumers process information drawn from more than one domain.

This research examined the effects of anxiety on subsequent message processing. Experiment 1, conducted just before the handover of Hong Kong to China in 1997, manipulated anxiety by presenting Hong Kong participants with negative or positive potential consequences of the handover. Consistent with research documenting the cognitive deficits produced by anxiety, lower levels of message elaboration were obtained under high (vs. low) anxiety for an anxiety-unrelated message.

Although diffusion models have been successfully used to predict the adoption patterns of new products and technologies, little research has examined the psychological processes underlying the individual consumers adoption decision. This study uses the knowledge transfer paradigm, studied often in the context of analogies, to demonstrate that both existing knowledge and innovation continuity are major factors influencing the consumers adoption process. In two experiments, the authors demonstrate that the relationship between expertise and adoption is relatively complex.

A Sunday New York Times article on a potential development of new cancer-curing drugs caused EntreMed's stock price to rise from 12.063 at the Friday close, to open at 85 and close near 52 on Monday. It closed above 30 in the three following weeks. The enthusiasm spilled over to other biotechnology stocks. The potential breakthrough in cancer research already had been reported, however, in the journal Nature, and in various popular newspapers (including the Times) more than five months earlier.

In view of the distressingly low rate of success in new product introduction, it is important to identify predictive guidelines early in the new product development process so that better choices can be made and unnecessary costs avoided. In this paper, a framework for early analysis based on the success potential embodied in the product-idea itself and the circumstances of its emergence. Based on two studies reporting actual introductions, several determinants are identified that significantly distinguish successful from unsuccessful new products in the marketplace.

We examine consumers' price sensitivity using a new approach that incorporates probabilistic thresholds for price gains and price losses in the reference price models. We model the threshold as a function of company, competitor and consumer specific factors. Model application to scanner panel data for coffee shows that our model is superior in fit compared to ordinary logit and two existing reference price models.

A long and rich tradition in Western-dominated social psychology has examined the effects of people's observations of their own behavior on their subsequent attitudes and behaviors. Studies in this tradition examine and find moderating effects of various contextual factors (e.g., volition and publicness) on people's tendencies to align their attitudes/behaviors with their observed behaviors. Conversely, there has been a historical tradition for examining the effects of social influences and group pressure on human thought and behavior.

For almost half a century, researchers have examined consumer knowledge of prices, often with disturbing and conflicting results. Although the general findings suggest that consumer knowledge of prices is poorer than assumed in neoclassical economic theory, significant variations among results exist. The authors synthesize findings from prior studies to determine the impact of research design choices on price recall accuracy measures.
