Consumer Behavior

We examine how consumers update their confidences in ordinal (relative) judgments while evaluating sequential product-ranking and source-accuracy data in percentage versus frequency formats. The results show that when sequential data are relatively easier to mathematically combine (e.g., percentage data), consumers revise their judgments in a way that is consistent with an averaging model but inconsistent with the normative Bayesian model.

In this research we propose a web-based adaptive self-explicated approach for multi-attribute preference measurement (conjoint analysis) with a large number (ten or more) of attributes. Our approach overcomes some of the limitations of previous self-explicated approaches. We developed a computer-based self-explicated approach that breaks down the attribute importance question into a sequence of constant-sum paired comparison questions.

Combinatorial auctions (CAs) are multi-unit auction mechanisms in which bidders can bid on combinations of items or packages. CAs have received considerable attention from academia, and their practical use has increased significantly over recent years especially in procurement projects. Units in procurement projects often exhibit cost synergies, and using a CA can be particularly advantageous to the auctioneer because it enables bidders to express their cost synergies in the bidding process.

The measurement and timing of reported revenue is critical to performance measurement and the development of accurate forecasting models. GM used incentives to get customers to buy its vehicles. This case asks students to consider how GM should report the sales so that the data is a valid indication of performance and can be used to accurately forecast future sales.

This article considers scientific and public understandings of climate change and addresses the following question: Why is it that while scientific evidence has accumulated to document global climate change and scientific opinion has solidified about its existence and causes, U.S. public opinion has not and has instead become more polarized? Our review supports a constructivist account of human judgment.

Engaging the public with climate change has proved difficult, in part because they see the problem as remote. New evidence suggests that direct experience of one anticipated impact — flooding — increases people's concern and willingness to save energy.

More and more firms are engaging in greenwashing, misleading consumers about their environmental performance or the environmental benefits of a product or service. The skyrocketing incidence of greenwashing can have profound negative effects on consumer and investor confidence in green products. Mitigating greenwashing is particularly challenging in a context of limited and uncertain regulation.
