Odd versus even prices and consumers' behavior.

Schindler and Kibarian reported prices ending with a nine were associated with more purchases among customers who were women. To generalize this effect to a new business context, two groups of 200 people were solicited at home and asked to buy pancakes to raise money for a charitable organization. In half of the cases, the price of pancakes was 1.99euro, and in the other half they were proposed at 2.00euro. Analysis showed that the price ending with nine was associated with more subjects agreeing to the request, 118 of 200 vs 91 of 200.

Sound level of background music and alcohol consumption: an empirical evaluation.

The effect of background music on alcohol consumption has been widely researched in the literature, but few studies have tested the effect of sound level on drinking behavior. An experiment was carried out in two bars to test patrons' response to music's loudness. Using random assignment, patrons were exposed to a sound level which was higher than that usually employed in the bars in which the study took place. Analysis showed that a higher sound level than usual was associated with consuming more drinks. An "arousal" hypothesis is used to explain the findings.

Social presence reinforcement and computer-mediated communication: the effect of the solicitor's photography on compliance to a survey request made by e-mail.

Personal information is scarce in computer-mediated communication. So when information about the sender is attached with an e-mail, this could induce a positive feeling toward the sender. An experiment was carried out where a male and a female student-solicitor, by way of an e-mail, requested a student-subject to participate in a survey. In half of the cases, a digital photograph of the solicitor appeared at the end of the e-mail. Results show that subjects agreed more readily to the request in the experimental condition than in the control condition where no digital photograph was sent with the e-mail. The importance of social information on computer-mediated communication is used to explain such results.

Solicitation by e-mail and solicitor's status: a field study of social influence on the web.

Personal information is scarce in computer-mediated communication. So when information about the sender is attached with his or her e-mail, this could induce a powerful effect toward the receptor. Two experiments were carried out where males and females were solicited by e-mail to respond to a survey on their foods habits. In the first experiment, students were solicited whereas, in the second experiment, people taken at random in various e-mails lists were solicited. The questionnaire was an HTML form attached with the e-mail. The signature of the solicitor was presented as of a high status (a scientist) or of a mid status (an undergraduate student). Results show that, in both experiments, subjects agreed more favorably to the request when the solicitor was of high status. The importance of social information on computer-mediated communication is used to explain such results.

Request solicitation and semantic evocation of freedom: an evaluation in a computer-mediated communication context.

The "But you are free of..." technique is a compliance procedure which solicits someone to comply with a request by simply telling him that he is free to accept or to refuse the request. This semantic evocation leads to increased compliance with the request. A new evaluation of the generality of this technique was tested in an experiment in which subjects received an anonymous electronic mail which asked them to consult the site of a humanitarian association for children. Analysis showed that, when the semantic evocation of freedom is included in the message, a higher compliance rate was observed than in a situation in which this evocation was omitted.
