Article Abstract:
Consumers often do not know the quality of a product when making their purchase decisions, which means demand is based on expectations rather than on complete information. The effects of private information acquired through product trial on consumer expectations, demand, and prices are modeled, with the effects shown to be incumbent on the quality of the product relative to consumer prior expectation, consumer perceptions of quality, consumer expectation revision mechanisms, and the number of purchasers.

Article Abstract:
The usefulness of unanticipated situational occurrences used to explain the disparity between stated intention and actual behavior for commonly consumed food and beverage products is examined. The study differs from other research on unexplained situations by monitoring actual situational occurrences for their effects on actual consumption as measured by garbage analysis and self-report. Behavior-intention inconsistency is shown to be partly attributable to unexpected situations.

Article Abstract:
The psychological framework of a preference hierarchy is integrated with the economic framework used in the analysis of the allocation of time and commodities. It is shown that residual income available to an activity is the major determinant of the level of an activity's time and commodity demands, as well as the most important variable affecting marginal consumption of new commodities.
