We argue that our understanding of industrial policy in the presence of โ€˜strategicโ€™ industries that exert positive externalities on the national economy may benefit from an extension of quantitative general equilibrium trade models making the extent and pattern of trade-induced reallocations more salient. To make these features relevant for national welfare, we introduce the notion of the โ€˜social footprintโ€™ of globalisation as the result of suboptimal trade-induced structural transformation in the presence of externalities. For proof of concept, we use simple workhorse models featuring two countries and two industries (only one of which is โ€˜strategicโ€™) to highlight the role of the โ€˜scale elasticityโ€™ of the strategic industry and the consequences of the most common assumptions on market structure in quantitative trade analyses.
