Purpose – The present study aims to analyse the sustainability of the trade deficits in the Association of Southeast Asian Nations (ASEAN)-5 countries using panel framework during the period from 1965 to 2011. Design/methodology/approach – The paper applied a battery of first- and second-generation panel unit root tests and Pedroni's, Kao and Chiang's, Westerlund, and Di Iorio and Fachin cointegration tests to achieve the objective. Findings – The paper found the evidence of sustainable trade deficit in ASEAN-5 countries while utilizing panel unit root tests as well as panel cointegration tests. Research limitations/implications – The findings have important macroeconomic policies implication for ASEAN-5 countries that these policies had been effective in leading exports and imports to long-run steady-state equilibrium relationship among the ASEAN-5 countries. Originality/value – The main contribution of the paper is to show that the macroeconomic policies of ASEAN-5 countries had been effective in leading exports and imports to long-run steady-state equilibrium relationship. To the authors' best knowledge, in this area, this is the first study in the panel framework for ASEAN countries.

Purpose The purpose of this paper is to examine the presence of unit roots in the stock prices of 16 OECD countries. Design/methodology/approach Heterogeneous panel unit root tests developed by Im et al. (1997/2003) and Pesaran (2007). Findings Under the assumption of cross-sectional independence across the panel, the authors find no evidence of unit roots, thus failing to reject mean reversion in the stock prices for all the countries in the sample. However, under the assumption of cross-sectional dependence, an assumption borne out by the diagnostic test results, the authors find support for the presence of unit roots in the stock prices. Practical implications Thus, the use of more robust panel unit root tests seems to raise questions about the long-run predictability of the stock market, at least in the context of the OECD countries. Originality/value Thus, it seems that in the long run, an investment policy of buy and hold has still much to offer.

Saving Rates

This paper investigates the causal relationship between gross domestic investment (INV) and saving rates for 40 Asian countries by using panel unit root tests and panel cointegration analysis for the period 1970-2010. The results indicate no long run relationship as well as no causalities between these two variables in these countries. The findings are attributed to non stationary deficits or surpluses in current accounts.

PurposeIn this study, we aim to test the stochastic convergence of per capita clean energy use in 30 OECD (Organization for Economic Co-operation and Development) countries for the period of 1965–2017.Design/methodology/approachThis study employed both linear and nonlinear panel unit root tests, and unlike other studies, this study allowed fractional values in addition to integer values for frequencies in the Fourier functions. Integer values of frequency indicate temporary breaks, while fractional values show permanent breaks.FindingsThe results of the linear panel unit root test indicate that clean energy use does not converge to group average for almost all OECD countries. However, the results of nonlinear panel unit root tests provide evidence that the stochastic convergence hypothesis of clean energy consumption cannot be rejected for most countries. This study does not find any evidence for stochastic convergence of clean energy use in Australia, Canada, Denmark, Ireland, Norway or Sweden. Therefore, the policies regarding clean energy are mandatory in these countries due to their effectiveness. This study also reveals that there are permanent structural breaks in the convergence process of clean energy consumption in approximately half of OECD countries.Originality/valueThis study considers temporary and permanent smooth structural shifts in addition to nonlinearity when testing the stationarity of clean energy consumption in a country i relative to the group average. This new method eliminates deficiencies of the previous panel data techniques. Thus, it provides more reliable results compared to existing literature.

PurposeThere are several studies that investigate evidence for mean reversion in stock prices. However, there is no consensus as to whether stock prices are mean reverting or random walk (unit root) processes. The goal of this paper is to re‐examine mean reversion in stock prices.Design/methodology/approachThe authors use five different panel unit root tests, namely the Im, Pesaran and Shin t‐bar test statistic, the Levin and Lin test, the Im, Lee, and Tieslau Lagrangian multiplier test statistic, the seemingly unrelated regression test, and the multivariate augmented Dickey Fuller test advocated by Taylor and Sarno.FindingsThe main finding is that there is no mean reversion of stock prices, consistent with the efficient market hypothesis.Research limitations/implicationsOne issue not considered by this study is the role of structural breaks. It may be the case that the efficient market hypothesis is contingent on structural breaks in stock prices. Future studies should model structural breaks.Practical implicationsThe findings have implications for econometric modelling, in particular forecasting.Originality/valueThis paper adds to the scarce literature on the mean reverting property of stock prices based on panel data; thus, it should be useful for researchers.

This study analyzes whether inflation targeting around the world has been successful in terms of achieving the announced target and keeping inflation rate around it. We argue that a successful inflation targeting necessitates the deviation of inflation from the target be stationary. We employ both time series and panel unit root tests in order to analyze the stationarity properties of deviation of inflation from the target.

Argumentamos que una meta exitosa de inflación requiere que la desviación de la inflación respecto a la meta sea estacionaria. Empleamos tanto series de tiempo como pruebas de raíz unitaria en panel con el fin de analizar las propiedades estacionarias de la desviación de la inflación en relación con el objetivo. Los resultados de las pruebas de raíz unitaria proporcionan evidencia a favor del éxito del marco de metas de inflación en todo el mundo.

Hysteretic Behaviour

Abstract Insider–outsider theory is often used as a basis for explaining the hysteretic behaviour of unemployment. Despite this, there is no empirical evidence about the validity of this theory on explaining the persistence of unemployment. This article addresses this gap, using various labour market proxies of insiders’ power for the OECD countries over 1960–2013 and employing panel unit root tests that exploit the information contained in these proxies. The results show that although the unemployment rate exhibits a pronounced hysteretic behaviour in OECD countries, this behaviour is reversed once we account for the insider–outsider proxies. Our findings thus validate the role of the insider–outsider theory as a key source of unemployment hysteresis.
