Purpose – This paper aims to investigate the integrational properties of real GDP for 125 countries. Design/methodology/approach – The paper applies the Kwiatkowski et al. univariate test and a KPSS-type univariate test that accounts for multiple structural breaks – a test procedure proposed by Carrion-i-Silvestre et al. The panel versions of the KPSS-type test, proposed by Carrion-i-Silvestre et al. with and without structural breaks, are also applied. Findings – The paper finds that, while univariate tests with and without structural breaks provide mixed results on persistence, the panel test suggests that shocks to national output are persistent. Originality/value – This is a multi-country study that focuses on both developed and developing countries and uses more recent data to provide new and comparable evidence on the persistence of output.

The goal of this paper is to test for asymmetric behaviour of macroeconomic aggregates for three Asian economies; namely, Malaysia, Hong Kong and Korea. Whether macroeconomic aggregates can be characterised as asymmetric has important implications for policy-making and econometric modelling including forecasting. We examine two forms of asymmetries; specifically deepness, which arises when a detrended time series contains an asymmetric distribution, and steepness, which arises when the first difference of a series contains an asymmetric distribution. Overall, our findings suggest that for all three countries, the bulk of the series display asymmetry behaviour. [ABSTRACT FROM AUTHOR]

In this paper, we analyse per capita income levels of China's three main regions: the western region, the eastern region and the central region using common cycle and common trend tests. Our main contribution is that we impose the common cycle and common trend restrictions in decomposing shocks into permanent and transitory components. We find that: (i) there is evidence for two cointegrating relationships and one common cycle; and (ii) the variance decomposition analysis of shocks provides evidence that over short horizons, permanent shocks play a large role in explaining variations in regional per capita incomes.

The aim of this article is to investigate whether there is a long-run relationship (cointegration) between exports and imports for 22 least developed countries (LDCs). This is an important issue, for evidence of cointegration will ensure that trade imbalances are sustainable. The article explores this issue using the bounds testing approach to cointegration. The results indicate that exports and imports are cointegrated only for six out of the 22 countries, and the coefficient on exports is less than one. [ABSTRACT FROM AUTHOR]

Purpose - This paper aims to estimate a disaggregated import demand model for Fiji using relative prices, total consumption, investment expenditure and export expenditure variables for the period 1970 to 2000. Design/methodology/approach - The recently developed bounds testing approach to cointegration to test for a long run relationship is used, while the autoregressive distributed lag model is used to estimate short run and long run elasticities. These methodologies are shown to perform well in small sample sizes, particularly given that the bounds F-test critical values for small sample sizes generated by Narayan in 2004 and 2005 are used. Findings - Amongst the key results it is found: a long run cointegration relationship among the variables when import demand is the dependent variable and import demand to be inelastic and statistically significant at the 1 per cent level with respect to all the explanatory variables in both the long-run and the short-run. Originality/value - The disaggregated import demand model estimated here provides a complete picture of the determinants of Fiji's imports. This model can be used by Fijian policy makers to draw pertinent policies and forecast import demand for Fiji. [ABSTRACT FROM AUTHOR]
