Standard sticky information pricing models successfully capture the sluggish movement of aggregate prices in response to monetary policy shocks but fail at matching the magnitude and frequency of price changes at the micro level. This paper shows that in a setting where firms choose when to...

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...

We present a model in which temporary shocks can permanently scar the economy's productive capacity. Unemployed workers lose skill and are expensive to retrain, generating multiple steady state unemployment rates. Large temporary shocks push the economy into a liquidity trap, generating...

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...

We present a microfounded two-country model of global imbalances and debt deleveraging. A sustained rise in saving in one country can lead to a worldwide fall in interest rates and an accumulation of debt in the other country. When a subsequent deleveraging shock occurs, interest rates are...

We investigate how bank migration across state lines over the last quarter century has affected the size and covariance of business fluctuations within states. Starting with a two-state version of the unit banking model in Holmstrom and Triocole (1997), we conclude that the theoretical effect of...

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...
