|Abstract:||We argue that the measures of backward linkages used in recent papers on spillovers from multinational companies are potentially problematic, as they depend on a number of restrictive assumptions, namely that (i) multinationals use domestically produced inputs in the same proportion as imported inputs, (ii) multinationals have the same input sourcing behaviour as domestic firms, irrespective of their country of origin, and (iii) the demand for locally produced inputs by multinationals is proportional to their share of locally produced output. We discuss why these assumptions are likely to be violated in practice, and provide alternative measures that overcome these drawbacks. Our results, using plant level data for Ireland, clearly show that the choice of backward linkage measure and thus, the assumptions behind it, matters greatly in order to draw possible conclusions regarding the existence of foreign direct investment (FDI)-related spillovers. Using the standard measure employed in the literaturewe fail to find robust evidence for spillovers through backward linkages. However, when we use alternative measures of backward linkages that relax assumptions (i)¿(iii), we find robust evidence for positive FDI backward spillover effects.|
