I develop a search-and-bargaining model of endogenous intermediation in over-the-counter markets. Unlike the existing work, my model allows for rich investor heterogeneity in three simultaneous dimensions: preferences, inventories, and meeting rates. By comparing trading-volume patterns that...

Classic models of fire-sales that emphasize liquidity-constrained natural buyers can-notfully account for the asset fire-sales during the Financial Crisis of 2008. I present a modelto demonstrate that fire-sales may happen even when there is a sizable pool of naturalbuyers and in the absence of...

We study a search and bargaining model of an asset market, where investors' heterogeneous valuations for the asset are drawn from an arbitrary distribution. Our solution technique renders the analysis fully tractable and allows us to provide a full characterization of the equilibrium, in...

Information processing filters out the noise in data but it takes time. Hence, low precision signals are available before high precision signals. To capture this feature, we develop a model of securities trading in which investors can acquire signals (about future cash flows) of increasing...

We propose a theory of asset prices that emphasizes heterogeneous information as the main element determining prices of different securities. Our main analytical innovation is in formulating a model of noisy information aggregation through asset prices, which is parsimonious and tractable, yet...

In this paper we study the impact of the degree of concentration of a financial system on the aggregate demand for housing as well as the feedback effect of the size of the mortgage loan market on lenders' profits, internal capital accumulation, loan losses and potential bailouts. In a general...

I show that households' demand for retail deposits decreases during stock market booms, which induces a contraction in bank lending and a decrease in real activity at bank-dependent firms. I identify this channel using geographic heterogeneity in households' stock market participation. Banks in...

We develop a dynamic matching and bargaining game with aggregate uncertainty about the relative scarcity of a commodity. We use our model to study price discovery in a decentralized exchange economy: Traders gradually learn about the state of the market through a sequence of multilateral...

We survey a representative sample of US households to study how exposure to the COVID-19 stock market crash affects expectations and planned behavior. Wealth shocks are associated with upward adjustments of expectations about retirement age, desired working hours, and household debt, but have...
