The present paper contributes to the literature dealing with this question, by evaluating the relative importance of two distinct channels through which trade costs are supposed to influence growth and welfare. The first channel is an "allocation effect" concerning the distribution of inputs across economic sectors. The second channel is a "location effect" concerning the geographical distribution of firms across countries. Since the growth and welfare effects exerted by tariff barriers through these mechanisms may be qualitatively and quantitatively different, an analysis allowing for both is in order. Though essentially theoretical, the paper is motivated also by empirical concerns,

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 R&D based endogenous growth models) exert completely different growth effects. As a consequence, the theoretical form of the relationship between import duties and growth critically changes according to which kind of tariff barrier is mainly raised and no clear empirical link may be expected to emerge in a cross-section of economies characterized by sufficiently heterogeneous tariff policies.
