Financial Market Reactions to the Russian Invasion of Ukraine
This article analyzes financial market reactions to the Russia-Ukraine war with a focus on the opening weeks. Markets did not completely anticipate the war, and asset price reactions strengthened from the first week—when there were hopes for a quick resolution—to the second week, when prices generally peaked and began to partially revert to prewar values. Exposure to commodity trade and trade with Russia and Ukraine determined market perceptions of the riskiness of equity and foreign exchange assets. Credit default swap prices on sovereign debt and breakeven inflation rates indicate that ...

Regulating Decentralized Systems: Evidence from Sanctions on Tornado Cash
Blockchain-based systems are run by a decentralized network of participants and are designed to be censorship-resistant. We use sanctions imposed by the U.S. Department of Treasury on Tornado Cash (TC), a smart contract protocol, to study the impact and effectiveness of regulation in decentralized systems. We document an immediate and lasting impact on TC following the sanction announcement, measured by market reaction, transaction volume, and diversity of users. Still, net flows into TC contracts recover to and surpass pre-announcement levels for most pools, supporting viability of TC. ...

Intellectual Property, Tariffs, and International Trade Dynamics
The emergence of global value chains not only leads to a magnification of trade in intermediate inputs but also to an extensive technology diffusion among the different production units involved in arms-length relationships. In this context, the lack of enforcement of intellectual property rights has recently become a highly controversial subject of debate in the context of the China-U.S. trade negotiations. This paper analyzes the strategic interaction of tariff policies and the enforcement of intellectual property rights within a quantitative general equilibrium framework. Results indicate ...

On Wars, Sanctions and Sovereign Default
This paper explores the role of restrictions on the use of international reserves as economic sanctions. We develop a simple model of the strategic game between a sanctioning (creditor) country and a sanctioned (debtor) country. We show how the sanctioning country should impose restrictions optimally, internalizing the geopolitical benefits and the financial costs of a potential default from the sanctioned country.

Uncertainty and Hyperinflation: European Inflation Dynamics after World War I
Fiscal deficits, elevated debt-to-GDP ratios, and high inflation rates suggest hyperinflation could have potentially emerged in many European countries after World War I. We demonstrate that economic policy uncertainty was instrumental in pushing a subset of European countries into hyperinflation shortly after the end of the war. Germany, Austria, Poland, and Hungary (GAPH) suffered from frequent uncertainty shocks ? and correspondingly high levels of uncertainty ? caused by protracted political negotiations over reparations payments, the apportionment of the Austro-Hungarian debt, and border ...

Geopolitics Meets Monetary Policy: Decoding Their Impact on Cross-Border Bank Lending
We use bilateral cross-border bank claims by nationality to assess the effects of geopolitics on cross-border bank flows. We show that a rise in geopolitical tensions between countries — disagreements in UN voting, broad sanctions, or sentiments captured by geopolitical risk indices — significantly dampens cross-border bank lending. Elevated geopolitical tensions also amplify the international transmission of monetary policies of major central banks, especially when geopolitical tensions coincide with monetary policy tightening. Overall, our results suggest that geopolitics is roughly as ...

A History of U.S. Tariffs: Quantifying Strategic Trade-Offs in Tariff Policy Design
U.S. tariff policy has historically balanced competing goals—revenue, protection and reciprocity. Policy priorities have shifted over time in response to changing economic and political conditions. Using a calibrated general equilibrium model, we illustrate these trade-offs through the lens of tariff Laffer curves. A 70 percent tariff maximizes U.S. revenue only in the absence of retaliation; this optimum falls to 30 percent with reciprocal tariffs. A unilateral 25 percent tariff delivers the largest domestic consumption gains through favorable terms-of-trade effects, though these gains ...

Financial Sanctions, SWIFT, and the Architecture of the International Payments System
Financial sanctions, alongside economic sanctions, are components of the toolkit used by governments as part of international diplomacy. The use of sanctions, especially financial, has increased over the last seventy years. Financial sanctions have been particularly important whenever the goals of the sanctioning countries were related to democracy and human rights. Financial sanctions restrict entities—countries, businesses, or even individuals—from purchasing or selling financial assets, or from accessing custodial or other financial services. They can be imposed on a sanctioned ...

The Anatomy of Export Controls
Governments increasingly use export controls to limit the spread of domestic cutting-edge technologies to other countries. The sectors that are currently involved in this geopolitical race include semiconductors, telecommunications, and artificial intelligence. Despite their growing adoption, little is known about the effect of export controls on supply chains and the productive sector at large. Do export controls induce a selective decoupling of the targeted goods and sectors? How do global customer-supplier relations react to export controls? What are their effects on the productive sector? ...
