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...

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...

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...

We analyze nonlinear pricing with finite information. A seller offers a menu to a continuum of buyers with a continuum of possible valuations. The menu is limited to offering a finite number of choices representing a finite communication capacity between buyer and seller.We identify necessary...

We analyze a nonlinear pricing model with limited information. Each buyer can purchase a large variety, d, of goods. His preference for each good is represented by a scalar and his preference over d goods is represented by a d-dimensional vector. The type space of each buyer is given by a...
