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.

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.

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.

<p class="run-in" align="center"><strong>ABSTRACT</strong></p><p>The popularity of inflation targeting has risen in the last decade and the number of countries that adopted inflation targeting as their monetary policy framework surpassed 40 by the end of 2016. 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. Results of unit root tests provide evidence in favor of the success of inflation targeting framework around the world.</p><p align="center"><strong> </strong></p><p align="center"><strong>¿HAN SIDO EXITOSAS LAS METAS DE INFLACIÓN?

Este estudio analiza si las metas de inflación alrededor del mundo han tenido éxito en términos de alcanzar el objetivo anunciado y mantener la tasa de inflación alrededor de su meta. 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.
