We document that attention to macroeconomic conditions is counter-cyclical using a natural-language-processing method that analyzes US public firms' regulatory filings. We rationalize this phenomenon as an optimal stochastic choice pattern in response to higher stakes for tracking macroeconomic...

We study how bounded rationality coevolves with the business cycle. We introduce a business-cycle model in which firms face a cognitive cost of making precise decisions. Theoretically, we characterize equilibrium with non-parametric, state-dependent stochastic choice. Firms have greater...

We study the macroeconomic implications of narratives, defined as beliefs about the economy that spread contagiously. In an otherwise standard business-cycle model, narratives generate persistent and belief-driven fluctuations. Sufficiently contagious narratives can "go viral," generating...

Modern theories of aggregate supply are built on the foundation that firms set prices and commit to producing whatever the market demands. We remove this strategic restriction and allow firms to choose supply functions, mappings that describe the prices charged at each quantity of production....

The notion that business cycles are driven by demand shocks is subtle. I first review some of the conceptual and empirical challenges faced when trying to accommodate this notion in micro-founded, general-equilibrium models. I next review my own research, which sheds new light on the observed...
