Inside trading with public information and market regulation

Abstract

In this study, we examine the insider trading model in the context of public information and market regulation. We find that when there is only one insider trader, regulators do not apply regulatory strategies for insider trading. However, regulators will regulate insider trading more strictly when there are multiple insider traders. Meanwhile, regulatory participation leads to more stable but less efficient markets.
