Asia Pacific Economic Papers 370
It is common to defi ne benefi t eligibility for small business policies by restrictions on the fi rm size. This paper investigates the incentives for a large fi rm to masquerade as many small fi rms by separately incorporating business segments, focusing on the case of the Japanese value-added tax. The paper fi nds that the masquerading was pervasive and took place quickly after the introduction of tax incentives. Tax avoidance caused 3.4 per cent of the overall revenue drain in 1990, thus reducing horizontal equity, but the effi ciency consequence would not have been severe. This study suggests that the masquerading by fi rms may be commonplace in other settings.
