Abstract

In the conventional economic perspective, people or investors are assumed to behave rationally when choosing investment alternatives to maximize their profits. Shiller (2000) showed that the Ponzi scheme is a form of irrational exuberance in which people or investors act irrationally. This study was aimed to investigate the impact of psychological biases (optimism bias, overconfidence, representativeness bias, confirmation bias, framing, and herding) to investors’ decisions to get involved in a Ponzi scheme. Regression analysis was employed to see the impact of these biases on the investment decisions. Data was collected through questionnaire from 38 investors (victims) who lived in several rural areas in Yogyakarta. The results of this study revealed that optimism bias, overconfidence, representativeness bias, confirmation bias, framing, and herding behavior have significant impact on investment decisions. However this study still has some limitations and needs further research.
