Uncertainty about the future rises in recessions. But is uncertainty a source of business cycles or an endogenous response to them, and does type matter? We propose novel SVAR identification strategy address these questions via inequality constraints on structural shocks. find that sharply higher macroeconomic recessions often output shocks, while financial markets likely fluctuations.

This paper combines a data-rich environment with machine learning algorithm to provide new estimates of time-varying systematic expectational errors (“belief distortions”) embedded in survey responses. We find sizable distortions even for professional forecasters, all respondent-types overweighting the implicit judgmental component their forecasts relative what can be learned from publicly available information. Forecasts inflation and GDP growth oscillate between optimism pessimism by large...

This paper provides a comprehensive survey of existing measures uncertainty, risk, and volatility, noting their conceptual distinctions. It summarizes how they are constructed, relative advantages in usage, effects on financial market economic outcomes. The divided into four categories based the construction methodology: news-based, survey-based, econometric-based, market-based measures. While heightened uncertainty is typically associated with negative real outcomes, magnitude these...

Abstract Using a sample of 39 countries representing 88% global GDP, we find that real economic uncertainty (REU) has negative long‐lasting domestic effects and transmits across countries. The international spillover REU are both statistically significant economically meaningful, trade ties play key role in explaining its transmission Innovations to the foreign component can contribute up 16% future variation industrial production. This effect is disproportionately larger on manufacturing...

Using monthly data on costly natural disasters affecting the United States over last 40 years, we estimate 2 time series models and use them to generate predictions about impact of COVID-19. We find that while our yield reasonable estimates industrial production number scheduled flight departures, they underestimate unprecedented changes in labor market.

<ns3:p>Using a sample of 30 countries representing about 65% the global GDP, we find that real economic uncertainty (REU) has negative long-lasting domestic effects and transmits across countries. The international spillover REU are (i) additional to those REUs, (ii) statistically significant, (iii) economically meaningful. Trade ties play key role in explaining why generated one country can affect outcomes other Based on this evidence, construct novel index for as...
