The literature on trade and growth provides several examples in which factor augmentation or technical progress can reduce the welfare of an open economy. The most famous example of such "immiserizing growth" is Bhagwati's (1958) demonstration that growth that expands the export industry can reduce welfare by causing the terms of trade to deteriorate. More recently, examples have been provided in which growth due to either factor expansion or technical progress in the presence of domestic distortions can be immiserizing even in a small, open economy. Johnson (1967), for example, shows that technical progress in the import-competing industry or growth of the factor used intensively in that industry can reduce welfare if the industry is protected by a tariff. Similarly, Bhagwati (1969) shows that the presence of factor market distortions also introduces the possibility of immiserizing growth. He concludes more generally that growth may be immiserizing in the presence of any of several types of distortions.
While the possibility of immiserizing growth in the presence of distortions has been recognized, little has been said about conditions under which growth is necessarily non-beneficial or non-harmful. The present paper derives sufficient conditions for growth, in the form of either factor augmentation or technical progress, not to immiserize a small, open economy characterized by variable returns to scale (VRS), production and consumption taxes, tariffs and factor market distortions. Moreover, in each case we provide an explicit condition for the effect of growth on welfare when growth takes the form of an infinitesimal increase in a factor supply or improvement in technology.[1].
