This paper analyzes financial intermediation chains in a search model with an endogenous intermediary sector. We show that the chain length and price dispersion among interdealer trades are decreasing in search cost, search speed, and market size but increasing in investors' trading needs. Using...

We analyze financial intermediation chains in a search economy, which is populated by investors with heterogeneous valuations of an asset. In equilibrium, investors with moderate valuations choose to be intermediaries, while those with extreme valuations are their customers. The average length...

Collateral frictions have a profound effect on our economic landscape, ranging from the design of financial securities, laws, institutions, to various rules and regulations. We analyze a model with disagreement, where securities and collateral requirements are endogenous. It shows that the...

Safe and liquid assets, such as Treasury bonds, are money-like instruments that command a convenience yield. We analyze this in a search model of two assets that differ in liquidity and safety. In contrast to the reduced-form approach, which puts the safe and liquid asset in utility function, we...

I generalize the long-run risks (LRR) model of Bansal and Yaron (2004) by incorporating recursive smooth ambiguity aversion preferences from Klibanoff et al. (2005, 2009) and time-varying ambiguity. Relative to the Bansal-Yaron model, the generalized LRR model is as tractable but more flexible...

How many interest rate hikes is quantitative tightening (QT) equivalent to? In this paper, I examine this question based on the preferred-habitat model in Vayanos and Vila (2021). I define the equivalence between rate hikes and QT such that they both have the same impact on the 10-year yield....
