I test the disposition effect, the tendency of investors to hold losing investments too long and sell winning investments too soon, by analyzing trading records for 10,000 accounts at a large discount brokerage house. These investors demonstrate a strong preference for realizing winners rather than losers. Their behavior does not appear to be motivated by a desire to rebalance portfolios, or to avoid the higher trading costs of low priced stocks. Nor is it justified by subsequent portfolio performance. For taxable investments, it is suboptimal and leads to lower after-tax returns. Tax-motivated selling is most evident in December. THE TENDENCY TO HOLD LOSERS too long and sell winners too soon has been labeled the disposition effect by Shefrin and Statman ~1985!. For taxable investments the disposition effect predicts that people will behave quite differently than they would if they paid attention to tax consequences. To test the disposition effect, I obtained the trading records from 1987 through 1993 for 10,000 accounts at a large discount brokerage house. An analysis of these

Price promotions are used extensively in marketing for one simple reason -- consumers respond. The sales increase for a brand on promotion could be due to consumers accelerating their purchases (i.e., buying earlier than usual and/or buying more than usual) and/or consumers switching their choice from other brands. Purchase acceleration and brand switching relate to the primary demand and secondary demand effects of a promotion. Gupta (1988) captures these effects in a single model and decomposes a brand's total price elasticity into these components. He reports, for the coffee product category, that the main impact of a price promotion is on brand choice (84%), and that there is a smaller impact on purchase incidence (14%) and stockpiling (2%). In other words, the majority of the effect of a promotion is at the secondary level (84%) and there is a relatively small primary demand effect (16%). This paper reports the decomposition of total price elasticity for 173 brands acros...

We review extensive evidence about how psychological biases affect investor behavior and prices. Systematic mispricing probably causes substantial resource misallocation. We argue that limited attention and overconfidence cause investor credulity about the strategic incentives of informed market participants. However, individuals as political participants remain subject to the biases and self-interest they exhibit in private settings. Indeed, correcting contemporaneous market pricing errors is probably not government’s relative advantage. Government and private planners should establish rules ex ante to improve choices and efficiency, including disclosure, reporting, advertising, and default-option-setting regulations. Especially

Two behavioral concepts, loss aversion and mental accounting, have been combined to provide a theoretical explanation of the equity premium puzzle. Recent experimental evidence supports the theory, as students ’ behavior has been found to be consistent with myopic loss aversion (MLA). Yet much like certain anomalies in the realm of riskless decision-making, these behavioral tendencies may be attenuated among professionals. Using traders recruited from the CBOT, we do indeed find behavioral differences between professionals and students, but rather than discovering that the anomaly is muted, we find that traders exhibit behavior consistent with MLA to a greater extent than students.

All around the world, in both the public and private sectors, retirement plans are shifting away from “defined benefit” plans toward “defined contribution” plans. Poterba, Venti, and Wise (2006), for example, followed the cohort of Americans who were 45 years old in 1984 and report a decrease in defined benefit plan coverage from about 40 percent to 20 percent and a corresponding increase in defined contribution plan coverage from about 5 percent to more than 30 percent. Defined contribution plans have many attractive features for participants, such as portability and flexibility, but these attractions come with an increased responsibility to choose wisely. The plans also provide economists with an attractive domain in which to study saving behavior. The standard economic theories of saving (like the life-cycle or permanent income models) contain three embedded rationality assumptions, one explicit and two implicit. The explicit assumption is that savers accumulate and then decumulate assets to maximize some lifetime utility function (possibly including bequests). The first implicit assumption is that households have the cognitive ability to solve

We study the trading of individual investors using transaction data and identifying buyeror seller-initiated trades. We document four results: (1) Small trade order imbalance correlates well with order imbalance based on trades from retail brokers. (2) Individual investors herd. (3) When measured annually, small trade order imbalance forecasts future returns; stocks heavily bought underperform stocks heavily sold by 4.4 percentage points the following year. (4) Over a weekly horizon small trade order imbalance reliably predicts returns, but in the opposite direction; stocks heavily bought one week earn strong returns the subsequent week, while stocks heavily sold earn poor returns.

The concept of perceived value: a systematic review of the research Raquel Sánchez-Fernández and M. Ángeles Iniesta-Bonillo University of Almería, Spain Abstract. The purpose of this article is to present a systematic review of the extensive research that has been conducted on the conceptualization of perceived value. The major conclusions of the present study are: (i) that both uni-dimensional and multidimensional models of value have their roles to play in providing simplified (unidimensional) and complex (multi-dimensional) understandings of the concept; (ii) that the nature of perceived value is complex and multi-dimensional; (iii) that the concept of perceived value implies an interaction between a consumer and a product; (iv) that value is relative by virtue of its comparative, personal, and situational nature; and (v) that value is preferential, perceptual, and cognitive-affective in nature. By organizing and synthesizing the major research streams and the individual studies within them, the present study thus provides a comprehensive framework for future studies of the dimensionality of perceived value.
