Using a database of up to 62 variables for 196 countries over 57 years, a hyperinflation cycle has been characterized to propose a broader setting of stylized facts. Beyond the usual facts, the findings in this paper contribute to the literature of modern hyperinflations in that these cycles...

The welfare cost of random consumption fluctuations is known from DeSantis (2007) to be increasing in the level of individual consumption risk in the economy. It is also known from Barillas et al. (2009) to increase if agents in the economy care about robustness to model misspecification. In...

Public officials have blamed Wall Street and its complex financial products for causing the 2008 economic downturn. This article addresses three popular claims saying that complex financial markets are at fault and need more regulation. It argues that even in the midst of a major economic...

We introduce frictional financial intermediation into a HANK model. Households are subject to idiosyncratic and aggregate risk and smooth consumption through savings and consumer loans intermediated by banks. The banking friction introduces an endogenous countercyclical spread between the...

This paper traces the evolution of John Maynard Keynes’s theory of the business cycle from his early writings in 1913 to his policy prescriptions for the control of fluctuations in the early 1940s. The paper identifies six different “theories” of business fluctuations. With different...

How can we measure the welfare benefit of ongoing stabilization policies? We develop a methodology to calculate the welfare cost of business cycles taking into account that observed consumption is partially smoothed. We propose a decomposition that disentangles consumption in a mix of...

The argument that policy risk, i.e., uncertainty about monetary and fiscal policy, has been holding back the economic recovery in the U.S. during the Great Recession has a large popular appeal. We analyze the role of policy risk in explaining business cycle fluctuations by using an estimated New...

I study optimal monetary policy in the presence of non-fundamental sources of fluctuations. Beliefs about aggregate demand can be self-fulfilling in models departing slightly from the complete information benchmark in the New Keynesian framework. Through its effect on aggregate variables, the...

We introduce frictional financial intermediation into a HANK model. Households are subject to idiosyncratic and aggregate risk and smooth consumption through savings and consumer loans intermediated by banks. The banking friction introduces an endogenous countercyclical spread between the...

Numerous countries have experienced boom-bust episodes in asset prices in the past 20 years. This study looks at stylized facts and conducts statistical and econometric analysis for such episodes, distinguishing between industrialized countries that experienced external adjustment (via real...
