A basic tenet of lognormal asset pricing models is that a risky currency is associated with low pricing kernel volatility. Empirical evidence indicates that a risky currency is associated with a relatively high interest rate. Taken together, these two statements associate high-interest-rate...

High interest rate currencies tend to appreciate. This is the uncovered interest rate parity (UIP) puzzle. It is primarily a statement about short-term interest rates and how they are related to exchange rates. Short-term interest rates are strongly affected by monetary policy. The UIP puzzle,...

A defining friction of sovereign debt is the lack of collateral that can back sovereign borrowing. This paper shows that credit default swaps (CDS) can serve as collateral and thereby support more sovereign borrowing. By giving more bargaining power to lenders in ex-post debt renegotiations, CDS...

OTC markets exhibit a core-periphery network: 10-30 central dealers trade frequently and with many dealers, while hundreds of peripheral dealers trade sparsely and with few dealers. Existing work rationalize this phenomenon with exogenous dealer heterogeneity. We build a search-based model of...

I build a dynamic search model of bond and CDS markets and show that allowing short positions through CDS contracts increases liquidity of the underlying bond market. This result contrasts with existing theories on derivatives, which show that derivatives fragment traders across the derivative...
