A
new model of consumer behavior is developed using a hybrid of cognitive psychology and microeconomics.
The development of the model starts with the mental coding of combinations of gains and losses using the prospect theory value function. Then the evaluation of purchases is modeled using the new concept of
“transaction utility.” The household budgeting process is also incorporated to complete the characterization of mental accounting. Several implications to marketing, particularly in the area of pricing, are developed.

Introduction
accounting system induces an individual to violate a simple economic principle. Example 1 violates the principle of fungibility. Money is not supposed to have labels attached to it. Yet the couples behaved the way they did because the $300 was put into both
“windfall gain” and “food” accounts. The extravagant dinner would not have occurred had each couple received a yearly salary increase of $150, even though that would have been worth more in present value terms. Example 2 illustrates that accounts may be both topically and temporally specific. A player’s behavior in a poker game is altered by his current position in that evening’s game, but not by either his lifetime winnings or losings nor by some event allocated to a different account altogether such as a paper gain in the stock market. In example 3 the violation of fungibility (at obvious economic costs) is caused by the
