Testing for unit roots in time series models with non-stationary volatility

Many of the key macro-economic and financial variables in developed economies are characterized by permanent volatility shifts. It is known that conventional unit root tests are potentially unreliable in the presence of such behaviour, depending on a particular function (the variance profile) of the underlying volatility process. Somewhat surprisingly then, very little work has been undertaken to develop unit root tests which are robust to the presence of permanent volatility shifts. In this paper we fill this gap in the literature by proposing tests which are valid in the presence of a quite general class of permanent variance changes which includes single and multiple (abrupt and smooth-transition) volatility change processes as special cases. Our solution uses numerical methods to simulate the asymptotic null distribution of the statistics based on a consistent estimate of the variance profile which we also develop. The practitioner is not required to specify a parametric model for volatility. An empirical illustration using producer price inflation series from the Stock–Watson database is reported.

Barriers to employee rights: Gender,selection, and the labor process

This article applies a labor process analysis to the issue of employment rights in the particular context of gender inequality and unlawful discrimination in the recruitment process. It criticizes conventional perspectives on employee rights for their failure to examine critically managerial power and prerogative and its implications for gender inequality. The article outlines two particular labor process theories of gender divisions and inequality. In exploring the strengths and weaknesses of these more critical perspectives, the article highlights the analytical significance that they ascribe to power asymmetries in the labor process and labor market. Building on this perspective, the analysis then presents empirical data on gender discrimination in the selection practices of contemporary UK organizations. The research material reveals how gender discrimination can be reproduced, rationalized, and resisted. These empirical findings are theorized through a combined labor process analysis of power, knowledge, and identity in recruitment practices. We conclude that labor process analysis facilitates our understanding of the deep-seated barriers that continue to impede the protection of employee rights in workplace practices.
