We examine the importance of asset pricing anomalies (alphas) for the real economy. We develop a novel quantitative model with lumpy investment that features such informational inefficiencies and yields closed-form solutions for cross-sectional distributions of firm dynamics. Our findings...

We present a novel modeling approach for granular general equilibrium economies with persistent heterogeneity that yields exact global solutions. A key feature of our approach is the use of stochastic lumpy adjustment (SLA) technologies. The associated stochastic structure can capture any degree...

We characterize optimal voluntary disclosures by a privately informed agent facing a counterparty endowed with market power in a bilateral transaction. Although disclosures reveal some of the agent's private information, they may increase his information rents by mitigating the counterparty's...

Over-the-counter (OTC) markets attract substantial trading volume despite exhibiting frictions absent in centralized limit-order markets. We compare the efficiency of OTC and limit-order markets when traders' expertise is endogenous. We show that asymmetric access to counterparties in OTC...

Decentralized markets attract large amounts of trade volume, even though they exhibit frictions absent in centralized exchanges. We develop a model with asymmetric information and expertise acquisition where some traders try to exploit any market structure to inefficiently screen their...
