Abstract: This paper models trading on expert advice to study the impact of a financial transaction tax on traders’ information and decisions. The tax worsens expert advice by strengthening experts’ incentives to misreport information. This result advances the debate on tax suitability beyond the conventional arguments and provides a new explanation for the observed decline in informational efficiency after the tax introduction: the tax makes traders less informed. The model also generates testable predictions regarding the tax impact on mean and variance of trading volume. Finally, it sheds light on the relationship between the tax and regulation of expert compensation.
