Testing covariance stationarity
2006-11-01In this paper, we show that the widely used stationarity tests such as the KPSS test have power close to size in the presence of time-varying unconditional variance. We propose a new test as a complement of the existing ... -

Testing for super-exogeneity in the presence of common deterministic shifts
2001-11-22This paper introduces the concept of common deterministic shifts (CDS). This concept is simple, intuitive and relates to the common structure of shifts or policy interventions. We propose a Reduced Rank technique to ... -
Testing unit root based on partially adaptive estimation
2004-03-01This paper proposes unit tests based on partially adaptive estimation. The proposed tests provide an intermediate class of inference procedures that are more efficient than the traditional OLS-based methods and simpler ... -
To cointegrate or not to cointegrate? That's a topological question
1997-10-16We show that for any multivariate I( 1) process which does not cointegrate, it is possible to find another process sufficient1y elose to it where cointegration applies. Closeness is defined in terms of the spectral density ... -

Two heads may not be better than one : corporate board structure, managerial self-dealing,and common agency
2004-09-16This paper compares the effects on corporate performance and managerial self-dealing in a situation in which the CEO reports to a single Board that is responsible for both monitoring management and establishing performance ... -
A unit root test based on partially adaptive estimation
2003-09-11This paper constructs a unit root test baseei on partially adaptive estimation, which is shown to be robust against non-Gaussian innovations. We show that the limiting distribution of the t-statistic is a convex combination ... -
