Foreign investors' changing appetite for risk-taking have been shown to be a key determinant of the global financial cycle. Such fluctuations in risk sentiment also correlate with the dynamics of UIP premia, capital flows, and exchange rates. To understand how these risk sentiment changes...

This paper investigates the implications of international financial sanctions for the reserve currency status of the US dollar. We propose a simple model of a reserve currency, demonstrate how the anticipation of financial sanctions can weaken the dollar's status, and evaluate the welfare...

This paper develops a framework to study the management of international reserves when a government faces the risk of a rollover crisis. In the model, it is optimal for the government to reduce its vulnerability by initially lowering debt, and then increasing both debt and reserves as it...

We study the effects of debt-financed fiscal transfers in a general equilibrium, heterogeneous-agent model of the world economy. In the long run, increases in government debt anywhere raise the world interest rate and increase private wealth everywhere. In the short run, a country with a...

Are unregulated capital flows excessive during a stagflation episode? We argue that they likely are, owing to a macroeconomic externality operating through the economy's supply side. Inflows raise domestic wages through a wealth effect on labor supply and cause unwelcome upward pressure on...

After remaining close to 1 US Dollar since its inception in November 2020, the algorithmic stablecoin UST crashed in the two weeks of May 9th to May 15th, 2022, leading to a price collapse of the underlying LUNA token and the erasure of more than 50 Billion U.S. Dollar or 90% in market value

Frequent, yet uninformed, fund flows in Chilean pension plans generate substantial trading in currency markets due to the high allocation to international securities. These non-fundamental flows have a significant impact on the Chilean peso, which is estimated to have a relatively low price...

In this paper we revisit the Canadian experience with floating exchange rates since 1950. Canada was a pioneer in successfully adopting a floating exchange rate during the Bretton Woods pegged exchange rate regime. Since then, most advanced countries have followed the Canadian example

We study international trade and macroeconomic dynamics triggered by the imposition of sanctions. We begin with a tractable two-country model where Home and Foreign countries have comparative advantages in production of differentiated consumption goods and a commodity (e.g., gas), respectively....

We study the distribution of labor income during large devaluations. Across countries, inequality falls after large devaluations within the context of a surge in inflation and a fall and subsequent recovery of real labor income. To better understand inequality dynamics, we use a novel...
