Abstract

Forward-looking investments determine the resilience of firms’ supply chains. Such investments may confer externalities on other firms in the production network. We compare the equilibrium and optimal allocations in a general equilibrium model with an arbitrary number of vertical production tiers. Our model features endogenous investments in resilience, endogenous formation of supply links, and sequential bargaining over quantities and payments between firms in different tiers. We derive policies that implement the first-best allocation, allowing for subsidies to input purchases, search efforts, and investments in resilience. We show that the optimal subsidies to resilience and transfers depend only on production function parameters of the pertinent tier. With common technological parameters across tiers, optimal subsidies to resilience (transfers) are larger (smaller) at the most upstream tier than at the middle tiers, while optimal search subsidies are always larger than subsidies for investment in resilience.

Abstract

As countries and firms struggle to increase the resilience of their supply chains, this paper looks at the global economic costs of supply chains decoupling using the Baqaee and Farhi (2023) multi-country and multi-sector model. In line with the most recent literature, we look into a decoupling of global supply chains along geopolitical lines as well as in strategic sectors. The rich model setup allows us to explore not only the long-run effects, but also the short-run costs stemming from rigid wages and low substitutability for factors of production and input goods. We find that, in terms of welfare losses, the costs of decoupling are roughly 5 times higher in the short-run compared to the long-run, while country losses are heterogeneous. A reshaping of supply chains increases the level of consumer prices in most countries, as well as producer prices, especially for trade-intensive manufacturing sectors. Supply chain decoupling entails also a reallocation of labour across skill levels between the two blocs. Finally, global trade would decrease substantially, driven by lower trade in intermediate inputs and a higher reliance of countries on domestic production.

Abstract

Firms and policy makers are increasingly looking at friend-shoring to make supply chains less vulnerable to geopolitical tensions. We test whether these considerations are shaping FDI flows, using investment-level data on almost 300,000 instances of greenfield FDI between 2003 and 2022. Estimates from a gravity model, which controls for standard push and pull factors, show an economically significant role for geopolitical alignment in driving the geographical footprint of bilateral investments. This result is robust to the inclusion of standard bilateral drivers of FDI--such as geographic distance and trade flows--and the strength of the effect has increased since 2018, with the resurgence of trade tensions between the U.S. and China. Moreover, our results are not limited to greenfield FDI, but hold also for M&As.

Abstract

This paper assesses differences in macroeconomic exposure to trade fragmentation along geopolitical lines across a large group of countries. Estimating structural gravity regressions for sector-level bilateral trade flows between 185 countries, we find that differences in individual countries’ geopolitical ties act as a barrier to trade, with the largest effects concentrated in a few sectors (notably, food and high-end manufacturing). As a result, countries’ exposure via trade to geopolitical shifts varies with their market size, comparative advantage, and foreign-policy alignments. Introducing our estimates into a dynamic many-country, many-sector quantitative trade model, we show that geoeconomic fragmentation – modelled as an increased sensitivity of trade costs to geopolitics and greater geopolitical polarization – generally leads to lower trade and incomes. However, emerging markets and developing economies (EMDEs) tend to see the largest impacts: real per-capita income losses for the median EMDE in Asia are 60 percent larger, and for the median EMDE in Africa 100 percent larger, than for the median advanced economy. This suggests that the costs of trade fragmentation could fall disproportionally on countries that can afford it the least.
