Utilizing the formal linearity test of Luukkonen, Saikkonen and Terasvirta (Biometrika, 75, 491-499, 1998) as diagnostic tool, the empirical finding suggests that the linear autoregressive (AR) model is inadequate in describing the real exchange rates behaviour of 11 Asian economies. It is noted...

This paper revisits the income convergence hypothesis by using the nonlinear unit root test of Kapetanios et al. [Kapetanios, G., Shin, Y. and A. Snell, 2003. Testing for a unit root in the nonlinear STAR framework. Journal of Econometrics 112, 359-379.]. Out of the 12 OECD income gaps in which...

Utilizing the standard linearity test of Luukkonen et al . (1988), the linear nature of all the Asian stock indices has been formally rejected. This finding warrants use of the nonlinear stationary test of Kapetanois et al . (2003), which is also constructed in the STAR framework, to investigate...

The Phillips curve trade-off between output and inflation has for long been a debatable issue in the study of macroeconomics. Both new classical and new Keynesian approaches give contending views in explaining the determinants of the trade-off. The main aim of this study is to investigate...

This study re-examines the validity of relationship between Singapore Dollar-US Dollar exchange rate and the relative price using the latest econometric methodologies that accounts for non-linearity. Among others, this study finds Exponential Smooth Transition Autoregressive (ESTAR)- type...

With plentiful of evidence supporting the presence of non-linearity in stock returns series, coupled with theoretical and empirical works suggesting a potential loss in standard Johansen cointegration method if the underlying data generating process is non-linear in nature, this study...

This study employs the Hinich portmanteau bicorrelation test (Hinich 1996; Hinich and Patterson 1995) as a diagnostic tool to determine the adequacy of Generalised Autoregressive Conditional Heteroscedasticity (GARCH) models for eight Asian stock markets. The bicorrelation test results demonstrate...

The finding of nonlinear cointegration between Asian exchange rates with the corresponding relatives prices and aggregate price levels based on Breitung’s (2001) nonparametric rank tests reinforces previous validations of Purchasing Power Parity by the parametric testing procedures. Hence, in...

The finding of exchange rate–relative price nonlinear cointegration relationship in Malaysia, among others, suggests that nonlinear Purchasing Power Parity (PPP) equilibrium may be regarded as reference point in judging the short run misalignment of the Ringgit currency and thereby...
