Recent theoretical and empirical work has cast doubt on the hypotheses of a linear Phillips curve and a symmetric quadratic loss function underlying traditional thinking on monetary policy. This paper studies the one-period optimal monetary policy problem under an asymmetric loss function...

I determine expected long-run inflation in a two-state New Keynesian model driven by natural interest-rate uncertainty. Monetary policy switches between discretion in ‘normal times’ and zero-lower-bound episodes when it is passive. Long-run US inflation ranges from −1.8% to +1.2% p.a.

Flight-to-quality during times of financial crisis is a feature of financial markets. Here, a simple strategic model demonstrates that some preference asymmetry is sufficient to generate endogenous flight-to-quality from an emerging stock market to US Treasury bonds. The empirical evidence from...

Why should risk management systems account for parameter uncertainty? In addressing this question, the paper lets an investor in a credit portfolio face non-diversifiable uncertainty about two risk parameters - probability of default and asset-return correlation - and calibrates this uncertainty...
