Lag selection in subset VAR models with an application to a US monetary system
Brüggemann, Ralf; Lütkepohl, Helmut - 2000
Alternative modeling strategies for specifying subset VAR models are considered. It is shown that under certain conditions a testing procedure based on t-ratios is equivalent to sequentially eliminating lags that lead to the largest improvement in a prespecified model selection criterion. A...

Semiparametric diffusion estimation and application to a stock market index
Härdle, Wolfgang; Kleinow, Torsten; Korostelev, … - 2001
The analysis of diffusion processes in financial models is crucially dependent on the form of the drift and diffusion coefficient functions. A methodology is proposed for estimating and testing coefficient functions for ergodic diffusions that are not directly observable. It is based on...

Did the Fed surprise the markets in 2001? : a case study for VARs with sign restrictions
Uhlig, Harald - 2001
In 2001, the Fed has lowered interest rates in a series of cuts, starting from 6.5 % at the end of 2000 to 2.0 % by early November. This paper asks, whether the Federal Reserve Bank has been surprising the markets, taking as given the conventional view about the effect of monetary policy shocks....

In contrast to U.S. data we … find that the volatility depends on either the interest rate level or information shocks but not on both. Finally, we … propose to describe the short term interest rate's dynamics by means of an AR(1) model with stochastic volatility. -- Term …
