Multinationals and Linkages: An Empirical Investigation

by Laura Alfaro and Andres Rodriguez-Clare

Abstract

Several recent papers have used plant-level data and panel econometric techniques to carefully explore the existence FDI externalities. One conclusion that emerges from this literature is that it is difficult to find evidence of positive externalities from multinationals to local firms in the same sector (horizontal externalities). In fact, many studies find evidence of negative horizontal externalities arising from multinational activity while confirming the existence of positive externalities from multinationals to local firms in upstream industries (vertical externalities). In this paper we explore the channels through which these positive and negative externalities may be materializing, focusing on the role of backward linkages. In particular, we criticize the common usage of the domestic sourcing coefficient as an indicator of a firm's linkage potential and propose an alternative, theoretically derived indicator. We then use plant-level data from several Latin American countries to compare multinationals' linkage potential to that of domestic firms. We find that multinationals' linkage potential in Brazil, Chile and Venezuela is higher than for domestic firms. For Mexico, we cannot reject the hypothesis that foreign and local firms have similar linkage potential. Finally, we discuss the relationship between this finding and the conclusions that emerge from the recent empirical literature.

In the decades following 2005, China faced significant financial challenges. Inflation spiraled upwards and China’s economy stagnated in the wake of the Global Financial Crisis. The country’s leaders took an interventionist approach to weather the storm, controlling capital and exchange rates. These actions raised criticism from other nations, and in 2017 the U.S. initiated the U.S.-China Trade Wars, which enforced tariffs and requirements for increased transparency. As implications of the trade wars remained uncertain, many wondered whether the central bank would introduce further discreet steps to change the yuan. Would China’s currency appreciate as substantially against the U.S. dollar as predicted by economists? And when would further change occur? The stakes were high; a freer yuan float would impact groups within and outside of China very differently. Would China’s currency then be allowed to depreciate or appreciate if fundamentals required it?

For decades, Chile was heralded as South America’s pillar of stable economic growth. Chile was the world’s largest producer of copper and enjoyed a long period of over 30 years of world demand for its resources. In 2013, the commodity boom ended and was replaced by a slow period of economic activity. By 2019, a culmination of factors had contributed to widespread protests. Major streets in Santiago were shut down due to demonstrations by workers across 20 ports. Mining unions urged the government to lift the state of emergency and end curfews. It was unclear how these stoppages would affect copper production and prices in a country that produced a third of the world’s supply.
