Using U.S. data from 1926 to 2015, I show that financial skewness?a measure comparing cross-sectional upside and downside risks of the distribution of stock market returns of financial firms?is a powerful predictor of business cycle fluctuations. I then show that shocks to financial skewness are...

Speculation, in the spirit of Harrison and Kreps [1978], is introduced into a standard real business cycle model. Investors (speculators) hold heterogeneous beliefs about firm growth. Firm ownership, and thus, the firm's discount factor varies with waves of optimism and leverage. These waves...

Diagnostic expectations have emerged as an important departure from rational expectations in macroeconomics and finance. We present a first treatment of diagnostic expectations in linear macroeconomic models. To this end, we establish a strong additivity property for diagnostic expectations. The...

Swift changes in investors' sentiment, such as the one triggered by COVID-19 global outbreak in March 2020, lead to financial tensions and asset price volatility. We study the interactions of behavioral and financial frictions in an environment with endogenous risk-taking and capital...

Diagnostic expectations constitute a realistic behavioral model of inference. This paper shows that this approach for expectation formation can be productively integrated into the New Keynesian framework. To this end, we start by offering a first technical treatment of diagnostic expectations in...

This paper extends a quantitative medium-scale New-Keynesian DSGE model with financial intermediaries to account for shocks to investor confidence. Shocks of this nature manifest themselves as per period changes to financial intermediaries' leverage ratios. A Bayesian MCMC approach is utilized...

Swift changes in investors' sentiment, such as the one triggered by COVID-19 global outbreak in March 2020, lead to financial tensions and asset price volatility. We study the interactions of behavioral and financial frictions in an environment with endoge- nous risk-taking and capital...

We assess how survey expectations impact production and pricing decisions on the basis of a large panel of German firms. We identify the causal effect of expectations by matching firms with the same fundamentals but different views about the future. The probability to raise (lower) production is...

Based on a new survey question in a large and representative panel of German firms, this paper introduces a novel measure of managers' subjective uncertainty. I compare this measure of business uncertainty to respondents' business expectations and document a strong negative relationship....

Economists, observers and policy-makers often emphasize the role of sentiment as a potential driver of the business cycle. In this paper we provide three contributions to this debate. First, we critically survey the existing literature on sentiment (considering both confidence and uncertainty)...
