In many centralized matching markets, agents' property rights over objects are derived from a coarse transformation of an underlying score. Prominent examples include the distance-based system employed by Boston Public Schools, where students who lived within a certain radius of each school were...

Advanced economies feature complicated networks that connect households, firms, and regions. How do these structures affect the impact of fiscal policy and its optimal targeting? We study these questions in a model with input-output linkages, regional structure, and household heterogeneity in...

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...

Rapid declines in the prices of financial securities on low trading volume -- low volume crashes -- are ubiquitous. This paper proposes a dynamic model with informational asymmetries, costly short-selling, and endogenous liquidity trader participation to explain this phenomenon. Owing to...

We study the macroeconomic implications of viral, belief-altering narratives. Empirically, we use natural-language-processing methods to measure narratives in the text of all US public firms' end-of-year reports (Forms 10-K). We find that: (i) firms' hiring decisions respond strongly to...

In macroeconomic models, it is standard practice to assume that imperfectly competitive firms either set a price in advance and supply at the market-clearing quantity (price-setting) or set a quantity in advance and sell at the market-clearing price (quantity-setting). However, under imperfect...

We study a general class of consumption-savings problems with recursive preferences. We characterize the sign of the consumption response to arbitrary shocks in terms of the product of two sufficient statistics: the elasticity of intertemporal substitution (EIS) between contemporaneous...
