Mental accounting

 
Investment Dictionary: Mental Accounting

An economic concept established by economist Richard Thaler, which contends that individuals divide their current and future assets into separate, non-transferable portions. The theory purports individuals assign different levels of utility to each asset group, which affects their consumption decisions and other behaviors.

Investopedia Says:
The importance of this theory is illustrated in its application towards the economic behavior of individuals, and thus entire populations and markets. Rather than rationally viewing every dollar as identical, mental accounting helps explain why many investors designate some of their dollars as "safety" capital which they invest in low-risk investments, while at the same time treating their "risk capital" quite differently.

A concept first named by Richard Thaler (1980), mental accounting attempts to describe the process whereby people code, categorize and evaluate economic outcomes.

One detailed application of mental accounting, the behavioral life cycle hypothesis (Shefrin & Thaler, 1988), posits that people mentally frame assets as belonging to either current income, current wealth or future income and this has implications for their behavior as the accounts are largely non-fungible and marginal propensity to consume out of each account is different.

Mental accounting, utility, value and transaction

In mental accounting theory, framing means that the way a person subjectively frames a transaction in their mind will determine the utility they receive or expect. This concept is similarly used in prospect theory, and many mental accounting theorists adopt that theory as the value function in their analysis.

Another very important concept used to understand mental accounting is that of modified utility function. There are 2 values attached to any transaction - acquisition value and transaction value. Acquisition value is the money that one is ready to part with for physically acquiring some good. Transaction value is the value one attaches to having a good deal. If the price that one is paying is equal to the mental reference price for the good, the transaction value is zero. If the price is lower than the reference price, the transaction utility is positive.

Mental accounting cost

More generally, a mental accounting cost or mental transaction cost, a kind of transaction cost, is the cost of making a useful decision, especially of a consumer making a useful decision to buy, and may set a lower bound on useful price granularity in a market.
