Bursting the dot.com "Bubble': A Case Study in Investor Behaviour

Abstract

The Austrian economist Joseph Schumpeter considered innovation to be the driving force of economic growth and argued that innovations were also the main cause of cyclical fluctuations in the economy, an idea now well established in the economic literature. In this paper, the authors attempt to gain insights into the behaviour exhibited by investors before and after the market correction of the newly established Internet sector--a technology with revolutionary potential--in the Spring of 2000 by structuring their analysis around the psychological themes of heuristic-driven bias, frame dependence, and inefficient prices. Linear regression models are constructed using data collected on publicly traded Internet companies, market performance both before and after the collapse of the Internet sector stock prices in an attempt to assess whether or not market returns were correlated with certain specific measures of corporate internet performance. Finally, the authors draw inferences relating to the psychology of investor behaviour during this period based upon their empirical analysis, and conclude by summarizing the managerial implications of their findings.
