Information asymmetry in non-US stocks: The compounding and mitigating effects of tax havens and corruption

Abstract

This study examines the role of a country's position as a tax haven and its corruption level in the information asymmetry of non-United States (U.S.) stocks listed on the New York Stock Exchange. Based on the findings, non-U.S. stocks from countries with more pronounced attributes of tax havens and corruption levels have a higher probability of information-based trading and lower market liquidity. Meanwhile, a deeper analysis into the individual attributes of tax havens reveals that the main drivers of these effects include weak anti-avoidance measures and legal complexities, with lesser effects from double tax treaties. In addition, the influence of a country's corruption level on information asymmetry primarily depends on its position as a tax haven, with the highest levels of information asymmetry occurring in jurisdictions that possess strong tax haven attributes and high corruption levels. The implication of the findings is that reducing the influence of global tax havens, especially in regions with high corruption levels, can enhance market liquidity, ultimately benefiting investors and contributing to the overall stability and efficiency of financial markets.
