This Occasional Paper analyses how significant expansions in central banks’ mandates, roles and instruments can result in challenges to the independence of monetary policy. The paper reviews, in particular, some of the key challenges to central bank independence brought about by the global...

Before the crisis of 1997-98, the East Asian economies except for Japan but including China pegged their currencies to the U.S. dollar. To avoid further turmoil, the IMF now argues that these currencies should float more freely. However, our econometric estimations show that the dollar's...

We investigate the drivers of daily changes in the exchange value of the Chinese currency (CNY) since early 2016, when a new regime was introduced for setting the fix - the midpoint of the CNY's daily trading range against the U.S. dollar. Daily changes in the fix, which is announced just prior...

Climate change poses three specific but interrelated policy challenges: climate change mitigation, climate change adaptation (which includes building up resilience) and managing transition risks. The International Monetary Fund (IMF) is a multilateral institution with global reach and...

The share of U.S. dollar assets in the official foreign exchange reserve portfolios of central banks is sometimes taken as an indicator of dollar status. We show that the observed decline in the aggregate share of U.S. dollar assets does not stem from a systematic shift in currency preferences...

Since the end of the Great Recession, growth in health care spending has declined to historically low levels. There is disagreement over whether this decline was caused by falling incomes during the Great Recession (and therefore is likely to reverse once the recovery is complete) or whether the...

We estimate a workhorse dynamic stochastic general equilibrium (DSGE) model with an occasionally binding borrowing constraint. First, we propose a new specification of the occasionally binding constraint, where the transition between the unconstrained and constrained states is a stochastic...

We study the impact of the COVID-19 pandemic on euro area inflation and how it compares to the experiences of other countries, such as the United States, over the two-year period 2020-21. Our model-based calibration exercises deliver four key results: (1) compositional effects, or the switch...

We estimate a multi-country, multi-sector New Keynesian model to quantify the drivers of domestic inflation during 2020-23 in several countries, including the United States. The model matches observed inflation together with sector-level prices and wages. We further measure the relative...

This paper examines the determinants of cross-border flows of U.S. dollar banknotes, using a new panel data set of bilateral flows between the United States and 103 countries from 1990 to 2007. We show that a gravity model explains international flows of currency as well as it explains...
