Estimates of output gaps continue to play a key role in assessments of the stance of business cycles. This paper uses three approaches to examine the historical record of output gap measurements and their use in surveillance within the IMF. Firstly, the historical record of global output gap...

We argue that in an economy with downward nominal wage rigidity, the output gap is negative on average. Because it is more difficult to cut wages than to increase them, firms reduce employment more during downturns than they increase employment during expansions. This is demonstrated in a simple...

We study the properties of the IMF-WEO estimates of real-time output gaps for countries in the euro area as well as the determinants of their revisions over 1994-2017. The analysis shows that staff typically saw economies as operating below their potential. In real time, output gaps tend to have...

This paper studies the differences between fiscal multipliers in OECD economies across the credit cycle. Impulse responses are obtained using a state-dependent model with direct projections, in which multipliers depend on the state of credit markets. Identification of the effects of fiscal...

This paper estimates the impact of government spending shocks on economic activity during periods of high and low uncertainty and during periods of boom and recession. We find that government spending shocks have larger impacts on output in booms than in recessions and larger impacts during...

What are the output responses to fiscal policy? Despite important advances reported in the literature, quantifying the size of the fiscal multiplier remains a challenge. Indeed, the quest to estimate a unique fiscal multiplier is probably an ill-posed one. The magnitude of the multiplier may...

The Great Moderation (GM) is widely documented in the literature as one of the most important changes in the US business cycle. All the papers that analyze it use post-WWII data. In this paper, we set the GM for the first time against a long-dated historical backdrop, stretching back a century...

We assess the international spillovers of US monetary policy with a large-scale global VAR which models the world economy as a network of interdependent countries. An expansionary US monetary policy shock contributes to the emergence of a Global Financial Cycle, which boosts macroeconomic...
