Multinomial Choice: Data consists of consumer choices of various goods, along char­ acteristics. Let there be J choices and y = (y1, . . . , yJ ) where yj = 1 if good j is chosen and yj = 0 otherwise. Let x be observed characteristics of the goods and choices. Here a conditional density for y corresponds to conditional choice probabilities P (j|x, β), one for each j, with �J j=1 P (j|x, β) = 1 ...

People consume not only physical goods but also social interaction, and consumer choices depend on both intrinsic motivations (preferences for consumption) and extrinsic motivations (how choices impact social interactions). In this paper, we study how social identity, preference, and utility from social interaction shape consumer behavior and choice in the marketplace. Our contribution is two-f...

The current sustainability labeling landscape has been accused of creating unnecessary consumer confusion due to too much, complex, similar, and ambiguous information. Meta-sustainability is proposed as a solution. We provide the first evidence on added value this instrument based survey in USA (N = 518) Germany 520). Participants were randomly allocated one four different conditions: (1) tradi...

The research into consumer choices and acceptance of new products and services is normally discussed within the framework of diffusion of innovations and has traditionally relied on identifying consumer characteristics while focusing on the characteristics of innovations. The purpose of this study is to examine the impact of Identity theft on the perceived level of security mad trusting E-Comme...

Much has been said about ecolabeling in the last few years, with several studies investigating hypothetical consumer demand for ecolabeled seafood products, where the label indicates no overfishing of the stocks. Most studies have focused on consumers choosing between labeled and unlabeled products of the same species. In a recent survey done in the US, consumers were asked to trade-off amongst...

In effort to enhance sustainable development, manufacturers and retailers have collaborated to develop a standardized sustainability index based on supply chain life cycle information. However, it is unclear whether this index will help consumers make more sustainable purchases. Research conducted in a retail laboratory addresses consumer attitudes, purchase intentions, and product choices with...

Many choices consumers face are over outcomes that consist of multiple attributes. For instance, when deciding to purchase a particular product consumers must account for both its price and its brand. Although these choices are quite common, we know relatively little about how changes in consumer attention to specific attributes impacts decisions. We propose a new computational model, the multi...

This paper makes some preliminary steps towards a dynamic theory of consumer choices, restricted to the case of repeated small decisions. We assume that the consumer chooses among products, rather than among bundles, and that she bases her decision on a cumulative satisfaction index. Such a consumer is not necessarily "optimizing" and may be "satisficing" in the sense of Simon (1957). The aggre...

People can access information about choices in at least two ways: via summary descriptions that provide an overview of potential outcomes and their likelihood of occurrence or via sequential presentation of outcomes. Provided with the former, people make decisions from description; with the latter, they make decisions from experience. Recent investigations involving risky choices have demonstra...

Imagine you are standing at a street with heavy traffic watching someone on the other side of the road. Do you think your brain is implicitly registering your willingness to buy any of the cars passing by outside your focus of attention? To address this question, we measured brain responses to consumer products (cars) in two experimental groups using functional magnetic resonance imaging. Parti...
