The ratio of import duties to total imports is a widely used measure of tariff policy in growth empirics. However, no clear and robust relationship emerges from the statistical analysis linking such an index to growth. This paper argues that this failure may be explained by precise theoretical reasons. Total import duties are generated by different fiscal instruments, such as ad valorem and specific tariffs, which (according to the insights of endogenous growth theory) exert completely different growth effects. As a consequence, the exact form of the relationship between import duties and growth critically changes according to which kind of tariff barrier is mainly raised and may even disappear in a cross-section of economies characterized by sufficiently heterogeneous tariff policies.
