Herd behavior in financial markets: an experiment with financial market professionals

We study herd behavior in a laboratory financial market with financial market professionals. An important novelty of the experimental design is the use of a strategy-like method. This allows us to detect herd behavior directly by observing subjects' decisions for all realizations of their private signal. In the paper, we compare two treatments: one in which the price adjusts to the order flow in such a way that herding should never occur, and one in which the presence of event uncertainty makes herding possible. In the first treatment, subjects seldom herd, in accordance with both the theory and previous experimental evidence on student subjects. A proportion of subjects, however, engage in contrarianism, something not accounted for by the theory. In the second treatment, the proportion of herding decisions increases, but not as much as the theory would suggest. Moreover, contrarianism disappears altogether. In both treatments, in contrast with what theory predicts, subjects sometimes prefer to abstain from trading, which affects the process of price discovery negatively

Small scale behavior of financial data

A new approach is presented to describe the change in the statistics of the log return distribution of financial data as a function of the timescale. To this purpose a measure is introduced, which quantifies the distance of a considered distribution to a reference distribution. The existence of a small timescale regime is demonstrated, which exhibits different properties compared to the normal timescale regime. This regime seems to be universal for individual stocks. It is shown that the existence of this small timescale regime is not dependent on the special choice of the distance measure or the reference distribution. These findings have important implications for risk analysis, in particular for the probability of extreme events.Comment: 4 pages, 6 figures Calculations for the turbulence data sets were redone using the log return as the increment definition in order to provide better comparison to the results for financial asset

FINANCIAL CONTAGION AND INVESTORS BEHAVIOR

International capital markets, in general, seem to be volatile markets, influenced bymany factors, a phenomenon that affects both developed markets, as well as least developed, withemerging market economies suffering most because of this. It is clear, however, that volatility willremain for as long as it is delayed the adoption of specific measures at national and internationalfinancial architecture level, measures that may be necessary to reduce these risks, to limit theirimpact, and that the question financial market can relapse in a manner as efficiently as possible.investor behaviour, financial crisis, rational investor, irational investor, financial contagion

Financial literacy : an essential tool for informed consumer choice?

Increasingly, individuals are in charge of their own financial security and are confronted with ever more complex financial instruments. However, there is evidence that many individuals are not well-equipped to make sound saving decisions. This paper demonstrates widespread financial illiteracy among the U.S. population, particularly among specific demographic groups. Those with low education, women, African-Americans, and Hispanics display particularly low levels of literacy. Financial literacy impacts financial decision-making. Failure to plan for retirement, lack of participation in the stock market, and poor borrowing behavior can all be linked to ignorance of basic financial concepts. While financial education programs can result in improved saving behavior and financial decision-making, much can be done to improve these programs’ effectiveness

Nonrational Actors and Financial Market Behavior

The insights of descriptive decision theorists and psychologists, we believe, have much to contribute to our understanding of financial market macrophenomena. We propose an analytic agenda that distinguishes those individual idiosyncrasies that prove consequential at the macro-level from those that are neutralized by market processes such as poaching. We discuss five behavioral traits - barn-door closing, expert/reliance effects, status quo bias, framing, and herding - that we employ in explaining financial flows. Patterns in flows to mutual funds, to new equities, across national boundaries, as well as movements in debt-equity ratios are shown to be consistent with deviations from rationality.

Financial Constraints and Firm Export Behavior

The paper analyzes the link between financial constraints and firm export behavior. Our main finding is that firms enjoying better financial health are more likely to become exporters. The result contrasts with the previous empirical literature which found evidence that export participation improves firm financial health, but not that export starters display any ex-ante financial advantage. On the contrary, we find that financial constraints act as a barrier to export participation. Better access to external financial resources increases the probability to start exporting and also shortens the time before firms decide to serve foreign customers. This finding has important policy implications as it suggests that, in presence of financial markets imperfections, public intervention can be called for to help efficient but financially constrained firms to overcome the sunk entry costs into export markets and expand their activities abroad.Export; Firm heterogeneity; Financial constraints; Sunk costs

Herd behavior and contagion in financial markets

We study a sequential trading financial market where there are gains from trade, that is, where informed traders have heterogeneous private values. We show that an informational cascade (i.e., a complete blockage of information) arises and prices fail to aggregate information dispersed among traders. During an informational cascade, all traders with the same preferences choose the same action, following the market (herding) or going against it (contrarianism). We also study financial contagion by extending our model to a two-asset economy. We show that informational cascades in one market can be generated by informational spillovers from the other. Such spillovers have pathological consequences, generating long-lasting misalignments between prices and fundamentals

Knowledge and Preference in Reporting Financial Information

This article models respondent behavior in a financial survey with a framework explicitly integrating a respondent’s knowledge of and willingness to reveal his or her financial status. Whether a respondent provides a valid answer, a “don’t know”, or a “refusal” to a financial question depends on the interaction of his or her financial knowledge and preferences regarding revealing the knowledge. Using asset response and nonresponse data from the Health and Retirement Study (2000), we found that knowledge and preferences play interrelated roles in reporting financial information, that a respondent’s age, gender, education, and race and ethnicity are important predictors of respondent behavior, and that race and ethnicity affect a respondent behavior only via their influence on preferences, while gender only via its influence on knowledge. We also found strong heterogeneity in respondents’ financial knowledge and their willingness to reveal the knowledge.

Financial Literacy: The Impact of Financial Training in High School on the Credit Behavior of College Students

Managing credit is increasingly important not only for adults, but for college students. In recent years with sky rocketing tuition and easily available credit, college students find themselves with increasing debt burdens that result in serious and lasting financial problems. In response, financial literacy programs are emerging in hopes that better educated people will make healthy financial decisions, as well as responsibly manage credit. Research suggests that financial education should begin in high school so that young adults can effectively manage credit during the college years. This study assesses both college students’ financial knowledge and their credit management practices. Specifically, it examines whether Bryant University students retain and use the financial training from high school when making financial decisions and managing credit. The findings from this study illustrate that almost 75% of the 345 students that manage their own credit in college received financial training in high school and that although this training is negatively correlated with poor credit management behavior in college, the association is weak. This study further suggests that even with additional financial literacy training available in college, almost 60% of these students demonstrate poor credit management behavior. As a result, this study suggests that young people need to improve their credit management skills by setting budgets and employing good credit management techniques
