type="main" xml:lang="en" <title type="main">Abstract</title> <p>We propose an iterative decomposition that tests and accounts for multiple structural breaks in the mean, seasonality, dynamics and conditional volatility, while also accounting for outliers. Considering each component separately within each iteration leads to...</p>

This paper proposes an iterative procedure to discriminate between structural breaks in the coefficients and the disturbance covariance matrix of a system of equations, with recursive procedures then identifying individual coefficient shifts and separating volatility from correlation breaks....

This paper investigates the nature of nonlinearities in the monetary policy rule of the US Federal Reserve (Fed) using the flexible approach to nonlinear inference. We find that while there is significant evidence of nonlinearity for the period to 1979, there is little such evidence for the...

Employing the modified tests of Harvey, Leybourne and Taylor [Harvey, D.I., Leybourne, S.J. and Taylor, A.M.R., 2006. Modified tests for a change in persistence. Journal of Econometrics 134, 441-469.] for a single change in persistence and repartitioning the sample when a break is found, this...

We provide evidence on the nature of co-movement in monthly US and UK stock returns by investigating time-varying correlations in returns since 1980. There is a marked increase in correlations between these markets around 2000, which we attribute to globalization and model with a time-varying...

This paper investigates the movement of manufacturing inventories and production over the business cycle to arrive at an asymmetric structural equilibrium-correction model. Initially cross-correlation coefficients and deepness and steepness tests for skewness are utilized to present descriptive...
