We construct a sovereign default network by employing high-dimensional vector autoregressions obtained by analyzing connectedness in sovereign credit default swap markets. We develop four measures of centrality, namely, degree, betweenness, closeness, and eigenvector centralities, to detect...

Based on the theory of static replication of variance swaps we assess the sign and magnitude of variance risk premiums in foreign exchange markets. We find significantly negative risk premiums when realized variance is computed from intraday data with low frequency. As a likely consequence of...

Separate literatures study violations of uncovered interest parity using regression-based and portfolio-based methods. We propose a decomposition of these violations into a cross-currency, a between-time-and-currency, and a cross-time component that allows us to analytically relate...

In this paper, I examine the heterogeneous exposure of USD-denomination bonds (dollar bonds) to exchange rate risks. An appreciation of the US dollar increases the credit spread differential, referred to as the Foreign Discount, between dollar bonds issued by non-US and US firms. I provide both...

We jointly re-specify the relative purchasing power parity (RPPP) and uncovered interest rate parity (UIP) conditions as the (log) ratio of stochastic discount factors by inverting the market price of risk formula. Our empirical model provides new insights, which show that violations to UIP and...

We leverage supervisory microdata to uncover the role of global banks' risk limits in driving exchange rate dynamics. Consistent with a model of currency intermediation under risk constraints, shocks to dealers' risk limits lead to price and quantity adjustments in the foreign exchange market....

No-arbitrage implies a close link between exchange rates and interest returns, but evidence of that link has been elusive. This paper derives an exchange rate asset price model with consumption-risk adjustments. Interest rates and exchange rates reflect common risks which bias their reduced-form...

Changes in collateralization have been implicated in significant default (or near-default) events during the financial crisis, most notably with AIG. We have developed a framework for quantifying this effect based on moving between Merton-type and Black-Cox-type structural default models. Our...
