Trading frenzies and their impact on real investment

We study a model in which a capital provider learns from the price of a firm's security in deciding how much capital to provide for new investment. This feedback effect from the financial market to the investment decision gives rise to trading frenzies, in which speculators all wish to trade like others, generating large pressure on prices. Coordination among speculators is sometimes desirable for price informativeness and investment efficiency, but speculators' incentives push in the opposite direction, so that they coordinate exactly when it is undesirable. We analyze the effect of various market parameters on the likelihood of trading frenzies to arise.     

Understanding Factors Leading to Participation in Supplemental Instruction Programs in Introductory Accounting Courses

Abstract

Although studies have shown that supplemental instruction (SI) programs can have positive effects in introductory accounting courses, these programs experience low participation rates. Thus, our study is the first to examine the factors leading to student participation in SI programs. We do this through a survey instrument based on the Theory of Planned Behavior. Our study shows that students' attitudes toward the sessions affect their intent to participate in them. This attitude is influenced by students' perceptions that the sessions can help them in various ways. Results also show that influential others can influence student intent to participate in SI sessions. We also note that students' perceptions of the amount of personal control that they have over going to SI sessions have no effect on their participation in the sessions. We discuss how these findings can be leveraged to increase SI participation rates.     

Fast and frugal forecasting

Simple statistical forecasting rules, which are usually simplifications of classical models, have been shown to make better predictions than more complex rules, especially when the future values of a criterion are highly uncertain. In this article, we provide evidence that some of the fast and frugal heuristics that people use intuitively are able to make forecasts that are as good as or better than those of knowledge-intensive procedures. We draw from research on the adaptive toolbox and ecological rationality to demonstrate the power of using intuitive heuristics for forecasting in various domains including sport, business, and crime.     

SIMULATION OF PORTFOLIO RETURNS: VARYING NUMBERS OF SECURITIES AND HOLDING PERIODS

Variability may be measured around the long-run market return by combining the well-developed area of security diversification with the notion of time diversification. This non-traditional concept of diversifiable risk is illustrated with results of a very large scale simulation. The results are very general since the data used in the simulation consist of all firms on the Center for Research in Security Prices (CRSP) monthly return file from January 1926 through December 1977.

Market Making and Trading in Nasdaq Stocks

This paper examines the relations between the number of market makers, trading activity, and price improvement in Nasdaq stocks, using a model motivated by Grossman and Miller (1988). Results indicate a positive relation between the number of market makers and trading frequency, and that competition among market makers reduces effective bid-ask spreads. Results estimated using a simultaneous equations framework support the model predictions of Grossman and Miller. Results also indicate that trading frequency may be more important than trade size in determining the number of market makers.
