Why should risk management systems account for parameter uncertainty? In order to answer this question, this paper lets an investor in a credit portfolio face non-diversifiable estimation-driven uncertainty about two parameters: probability of default and asset-return correlation. Bayesian...

Confronted with a speculative attack on its currency peg, an authority weighs the short-term benefit of giving in and fine tuning the economy against the long-term benefit of credibility-enhancing resistance. In turn, speculators with heterogeneous beliefs face strategic uncertainty that peaks...

This paper illustrates various applications of the BIS international banking statistics. We first compare international bank flows to measures of real activity and liquidity and show that the international banking system is becoming a more important conduit for the transfer of capital across...

This paper develops an empirical procedure for analyzing the impact of model misspecification and calibration errors on measures of portfolio credit risk. When applied to large simulated portfolios with realistic characteristics, this procedure reveals that violations of key assumptions of the...

Do public policy signals improve the alignment of market outcomes with economic fundamentals? Existing work contends that, when individual players have an incentive to coordinate their actions, public policy signals could steer these actions away from the fundamentals. We argue that such a...

In the late 1990s, Morris and Shin proposed a new theoretical framework of financial crises, which generalised traditional models of strategic complementarity and self-fulfilling beliefs by incorporating idiosyncratic uncertainty about the state. The innovative feature of their framework is...

Could a less conservative central bank - one that faces a more severe time inconsistency problem - be less likely to succumb to an attack on a currency peg? Traditional currency-crisis models provide a firm answer: No. We argue that the answer stems from these models' narrow focus on how a...

Is systematic monetary policy a driver of the forward premium puzzle, i.e. the tendency of high interest-rate currencies to appreciate, thus strongly violating Uncovered Interest Parity (UIP)? We address this question by studying a battery of monetary policy rules in a small open economy that is...

We develop a measure of systemic importance that accounts for the extent to which a bank propagates shocks across the banking system and is vulnerable to propagated shocks. Based on Shapley values, this measure gauges the contribution of interconnected banks to systemic risk, in contrast to...
