The authors examine how the use of extreme value theory yields collateral requirements that are robust to extreme fluctuations in the market price of the asset used as collateral.
The author compares the performance of three Gaussian approximation methods - by Nowman (1997), Shoji and Ozaki (1998), and Yu and Phillips (2001) - in estimating a model of the nonlinear continuous-time short-term interest rate.
A new consistent test is proposed for the parametric specification of the diffusion function in a diffusion process without any restrictions on the functional form of the drift function.
The authors examine the evidence presented by Galí and Gertler (1999) and Galí, Gertler, and Lopez-Salido (2001, 2003) that the inflation dynamics in the United States can be well-described by the New Keynesian Phillips curve (NKPC).
