We study how investors respond to inflation combining a customized survey experiment with trading data at a time of historically high inflation. Investors' beliefs about the stock return-inflation relation are very heterogeneous in the cross section and on average too optimistic. Moreover, many...

What model features and calibration strategies yield a large average marginal propensity to consume (MPC) in heterogeneous agent models? Through a systematic investigation of models with different preferences, dimensions of ex-ante heterogeneity, income processes and asset structure, we show...

We provide a price theory for incomplete markets that extends the traditional Walrasian analysis. We derive formulas expressing the consumption response to current and future changes in interest rates and income. Our analysis provides a natural decomposition of these responses into substitution...

This paper characterizes the allocations that emerge in general equilibrium economies populated by households with preferences of the additive random utility type that make discrete consumption, employment or spatial decisions. We start with a complete markets economy where households can trade...

This paper develops a general equilibrium model to examine the role of information technology when intermediaries facilitate the origination and distribution of assets given information asymmetry. Information technology measures the informativeness of asset-quality signals received by...

I introduce money into an incomplete markets model with heterogeneous agents and uninsurable income risk. I show that the model exhibits both non-monetary and monetary equilibria, with the latter existing when income risk is sufficiently high. Using numerical methods, I characterize the...

Might firms' use of data create market power? To explore this hypothesis, we craft a model in which economies of scale in data induce a data-rich firm to invest in producing at a lower marginal cost and larger scale. However, the model uncovers much richer interactions between data, welfare and...

Households' and firms' subjective inflation expectations play a central role in macroeconomic and intertemporal microeconomic models. We discuss how subjective inflation expectations are measured, the patterns they display, their determinants, and how they shape households' and firms' economic...

The financial motivation to earn advertising revenue by spreading misinformation has been widely conjectured to be among the main reasons misinformation continues to be prevalent online. Research aimed at reducing the spread of misinformation has so far focused on user-level interventions with...

We demonstrate that cognitive constraints produce injustice in its most paradigmatic form: incorrect verdicts in judicial trials. Responding to a request for help, we conducted a field study in Mexican labor courts in which time pressure on the judges leads to their making mistakes, many of...
