Divided We Fall: Differential Exposure to Geopolitical Fragmentation in Trade
This paper assesses differences in countries’ macroeconomic exposure to trade fragmentation along geopolitical lines. 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). Consequently, 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 fragment...
The Intensive Margin in Trade
The Melitz model highlights the importance of the extensive margin (the number of firms exporting) for trade flows. Using the World Bank’s Exporter Dynamics Database (EDD) featuring firm-level exports from 50 countries, we find that around 50 percent of variation in exports is along the extensive margin—a quantitative victory for the Melitz framework. The remaining 50 percent on the intensive margin (exports per exporting firm) contradicts a special case of Melitz with Pareto-distributed firm productivity, which has become a tractable benchmark. This benchmark model predicts that, conditional on the fixed costs of exporting, all variation in exports across trading partners should occur o...
Dominant Currencies and External Adjustment
The extensive use of the US dollar when firms set prices for international trade (dubbed dominant currency pricing) and in their funding (dominant currency financing) has come to the forefront of policy debate, raising questions about how exchange rates work and the benefits of exchange rate flexibility. This Staff Discussion Note documents these features of international trade and finance and explores their implications for how exchange rates can help external rebalancing and buffer macroeconomic shocks.
The Dominant Currency Financing Channel of External Adjustment
We provide evidence of a new channel through which exchange rates affect trade. Using a novel identification strategy that exploits firms’ maturity structure of foreign currency debt around a large depreciation in Colombia, we show that firms experiencing a stronger debt revaluation of dominant currency debt due to a home currency depreciation compress imports relatively more while exports are unaffected. Dominant currency financing does not lead to an import compression for firms that export, hold foreign currency assets, or are active in the foreign exchange derivatives markets, as they are all hedged against a revaluation of their debt. These findings can be rationalized through the prism of a model with costly state verification and foreign currency borrowing. Quantitatively, the dominant currency financing channel explains a significant part of the external adjustment process in addition to the expenditure switching channel. Pricing exports in the dominant currency, instead of the producer’s currency, mutes the effect of dominant currency financing on trade flows.
The Tyranny of Nations
The Tyranny of Nations places the ground-shaking political and economic events of modern times in context. Palak Patel draws on his experience investing in government bond markets to demonstrate how the present fits a specific historical pattern that has defined the past 500 years. Modern-day trade liberalization and financial expansion all share distinct parallels with similar events in the 1600s and 1800s. Likewise, China's economic trajectory matches that of 19th-century Prussia and 17th-century France. And a certain British Prime Minister, foreshadowing Donald Trump's populism 150 years later, launched a similar attack on globalization after the financial crisis of 1866. In The Tyranny of Nations, there are no "isms"-no capitalism, socialism, or feudalism-but instead, only privileged interests vying for power. Challenging both the mainstream and its critics, Palak Patel shows how an endless cycle of cooperation and conflict between nations drives societal change. This unique perspective on the intersection of macroeconomics, history, and politics offers the reader a compass for navigating the future.
Confronting South Korea's Next Crisis
South Korea's economic miracle is a well-known story. However, today Korea is confronting a new set of internal and external risks, which may foreshadow the next crisis. The Korean economy has been struggling with the faltering growth momentum and the rise of unprecedented socio-economic problems over recent years well before the pandemic crisis. After abrupt downshifts to markedly slower growth in the early 2000s, economic growth has continued to decelerate. Koreans are grappling with slow income growth, all time-high household debt, high youth unemployment, inequality, and social polarization. Politics is in disarray and is incapable of directing social discourse for the common good. Rapid...
Trading with Friends in Uncertain Times
In this paper we seek to answer the question of how the patterns of bilateral trade are altered by rising trade policy uncertainty (TPU). Specifically, we investigate whether geopolitical alignments between country pairs determine how bilateral trade flows react during periods of greater uncertainty. Using a structural gravity framework augmented with a text-based TPU index and a geopolitical distance measure based on UN General Assembly voting records, we find a significant negative effect of the latter when TPU is elevated, indicating a shift to trading among “friends” in uncertain times.

Botswana: Selected Issues
Narrowing the Channel
While large, multinational corporations have supported the removal of tariffs, behind the scenes these firms have fought for protection in the form of product regulations, including testing, labeling, and registration requirements. Unlike tariffs, these regulations can raise fixed costs, excluding smaller firms from the market and shifting profits toward global giants. Narrowing the Channel demonstrates that globalization and globalized firms can paradoxically hinder rather than foster economic cooperation as larger firms seek to protect their markets through often unnecessarily strict product regulations. To illustrate the problem of regulatory protectionism, Robert Gulotty offers an in-dep...
Global Supply Chain Disruptions: Challenges for Inflation and Monetary Policy in Sub-Saharan Africa
The Covid-19 pandemic has led to a large disruption of global supply chains. This paper studies the implications of supply chain disruptions for inflation and monetary policy in sub-Saharan Africa. Increases in supply chain pressures have had a sizeable impact on headline, food, and tradable inflation for a panel of 29 sub-Saharan African countries from 2000 to 2022. Our findings suggest that central banks can stabilize inflation and output more efficiently by monitoring global supply chains and adjusting the monetary policy stance before the disruptions have fully passed through into all inflation components. The gains from monitoring supply chain disruptions are particularly large for open economies which tend to experience outsized second-round effects on the prices of non-tradable goods and services.
