The evolution of the IMS and IFS in the past several hundred years can be viewed through the lens of the Copernican heliocentric system developed over 500 years ago. We trace out the evolution across regimes of the IMS and IFS in terms of network representations of the Copernican system. We...

This paper finds that limited exchange rate flexibility in the form of "fear of appreciation" significantly slows adjustment of current account imbalances, providing novel support for Friedman's conjecture regarding exchange-rate flexibility. We present a new stylized fact: floaters have faster...

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...

We study the effects of an anticipated dollarization, announced today but planned to be implemented at some future date, in a simple open-economy model. Motivated by the profile of countries considering dollarization we make the following assumptions. First, the government faces a scarcity of...

In this paper I analyze the work on exchange rates and external imbalances by University of Chicago faculty members during the university's first hundred years, 1892-1992. Many people associate Chicago's views with Milton Friedman's advocacy for flexible exchange rates. But, of course, there was...

This paper develops a new econometric framework to estimate and classify exchange rate regimes. They are classified into four distinct categories: fixed exchange rates, BBC (band, basket and crawl), managed floating, and freely floating. The procedure captures the patterns of exchange rate...

This study utilizes the granular Japanese customs data from 2014 to 2020 to examine the exchange rate pass-through (ERPT) to Japanese import prices. It mainly focuses on the impact of the invoicing currency choice on ERPT. The ERPT elasticity in products invoiced in the exporter's currency is...

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...

We begin by examining determinants of aggregate foreign exchange reserve holdings by central banks (size of issuing country's economy and financial markets, ability of the currency to hold value, and inertia). But understanding the determination of reserve holdings probably requires going beyond...

We provide a liquidity-based theory for the dominant use of the US dollar as the unit of denomination in global debt contracts. Firms need to trade their revenue streams for the assets required to extinguish their debt obligations. When asset markets are illiquid, as modeled via endogenous...
