This paper proposes an efficient estimation method for Band Threshold Autoregressive (Band-TAR) models. Standard maximum-likelihood algorithms cannot be used here because the log-likelihood function is not differentiable with respect to the threshold parameter, and one commonly uses a grid...

The short-run dynamics of German mark and US dollar real exchange rates are investigated for a panel of 19 OECD economies in a vector error correction framework for the 1973-96 period. The novel persistence profiles approach of Pesaran and Shin (1996) indicates that the effect of system-wide...

The use of GLS to deal with cross-section dependence in panels is not feasible where N is large relative to T since the disturbance covariance matrix is rank deficient. Neither is it the appropriate response if the dependence results from omitted global variables or common shocks correlated with...

This paper explores the long run behaviour and short run dynamics of quarterly UK real interest rates, 1950-1999, in a threshold autoregressive framework. Using bootstrap LR extensions of the Enders and Granger (1998) threshold unit root and asymmetry tests, it finds support for sign and...
