A state space representation of a linearized DSGE model implies a VAR in terms of observable variables. The model is said be non-invertible if there exists no linear rotation of the VAR innovations which can recover the economic shocks. Non-invertibility arises when the observed variables fail to perfectly reveal the state variables of the model. The imperfect observation of the state drives a wedge between the VAR innovations and the deep shocks, potentially invalidating conclusions drawn from structural impulse response analysis in the VAR. The principal contribution of this chapter is to show that non-invertibility should not be thought of as an “either/or” proposition – even when a model has a non-invertibility, the wedge between VAR innovations and economic shocks may be small, and structural VARs may nonetheless perform reliably. As an increasingly popular example, so-called “news shocks” generate foresight about changes in future fundamentals – such as productivity, taxes, or government spending – and lead to an unassailable missing state variable problem and hence non-invertible VAR representations. Simulation evidence from a medium scale DSGE model augmented with news shocks about future productivity reveals that structural VAR methods often perform well in practice, in spite of a known non-invertibility. Impulse responses obtained from VARs closely correspond to the theoretical responses from the model, and the estimated VAR responses are successful in discriminating between alternative, nested specifications of the underlying DSGE model. Since the non-invertibility problem is, at its core, one of missing information, conditioning on more information, for example through factor augmented VARs, is shown to either ameliorate or eliminate invertibility problems altogether.

This volume of Advances in Econometrics is devoted to dynamic stochastic general equilibrium (DSGE) models, which have gained popularity in both academic and policy circles as a theoretically and methodologically coherent way of analyzing a variety of issues in empirical macroeconomics. The volume is divided into two parts. The first part covers important topics in DSGE modeling and estimation practice, including the modeling and role of expectations, the study of alternative pricing models, the problem of non-invertibility in structural VARs, the possible weak identification in new open economy macro models, and the modeling of trend inflation. The second part is devoted to innovations in econometric methodology. The papers in this section advance new techniques for addressing key theoretical and inferential problems and include discussion and applications of Laplace-type, frequency domain, empirical likelihood, and method of moments estimators.

This issue is a selected bibliography covering the subject of leadership.

Many Information Theoretic Measures have been proposed for a quantitative assessment of causality relationships. While Gouriéroux, Monfort, and Renault (1987) had introduced the so-called “Kullback Causality Measures,” extending Geweke’s (1982) work in the context of Gaussian VAR processes, Schreiber (2000) has set a special focus on Granger causality and dubbed the same measure “transfer entropy.” Both papers measure causality in the context of Markov processes. One contribution of this paper is to set the focus on the interplay between measurement of (non)-markovianity and measurement of Granger causality. Both of them can be framed in terms of prediction: how much is the forecast accuracy deteriorated when forgetting some relevant conditioning information? In this paper we argue that this common feature between (non)-markovianity and Granger causality has led people to overestimate the amount of causality because what they consider as a causality measure may also convey a measure of the amount of (non)-markovianity. We set a special focus on the design of measures that properly disentangle these two components. Furthermore, this disentangling leads us to revisit the equivalence between the Sims and Granger concepts of noncausality and the log-likelihood ratio tests for each of them. We argue that Granger causality implies testing for non-nested hypotheses.

Presents a special issue, enlisting the help of the author’s students and colleagues, focusing on age, sex, colour and disability discrimination in America. Breaks the evidence down into manageable chunks, covering: age discrimination in the workplace; discrimination against African‐Americans; sex discrimination in the workplace; same sex sexual harassment; how to investigate and prove disability discrimination; sexual harassment in the military; when the main US job‐discrimination law applies to small companies; how to investigate and prove racial discrimination; developments concerning race discrimination in the workplace; developments concerning the Equal Pay Act; developments concerning discrimination against workers with HIV or AIDS; developments concerning discrimination based on refusal of family care leave; developments concerning discrimination against gay or lesbian employees; developments concerning discrimination based on colour; how to investigate and prove discrimination concerning based on colour; developments concerning the Equal Pay Act; using statistics in employment discrimination cases; race discrimination in the workplace; developments concerning gender discrimination in the workplace; discrimination in Japanese organizations in America; discrimination in the entertainment industry; discrimination in the utility industry; understanding and effectively managing national origin discrimination; how to investigate and prove hiring discrimination based on colour; and, finally, how to investigate sexual harassment in the workplace.

In the last four years, since Volume I of this Bibliography first appeared, there has been an explosion of literature in all the main functional areas of business. This wealth of material poses problems for the researcher in management studies — and, of course, for the librarian: uncovering what has been written in any one area is not an easy task. This volume aims to help the librarian and the researcher overcome some of the immediate problems of identification of material. It is an annotated bibliography of management, drawing on the wide variety of literature produced by MCB University Press. Over the last four years, MCB University Press has produced an extensive range of books and serial publications covering most of the established and many of the developing areas of management. This volume, in conjunction with Volume I, provides a guide to all the material published so far.

This chapter examines the topic of internal branding from an organizational/behavioral science perspective, theoretically and empirically investigating how organizational members actually enact corporate brands. A mixed-method research procedure serves to surface conscious (i.e., deliberate) and unconscious (i.e., tacit) internal brand meaning enactments in an internationally operating Austrian corporate business-to-business (B2B) brand. The results are an evidence of the potential complexity of real-life internal branding processes that limit the possibility of achieving a cohesive intended internal implementation of corporate brands. The chapter concludes with the managerial implication that purposeful managerial interventions necessitate an understanding of the social system that is the target of the internal branding initiative

More than five years have passed since A Nation at Risk was published in 1983 by then‐Secretary of Education Terrance Bell's National Commission on Excellence in Education. Those years have seen the publication of an enormous body of both primary material, composed of research reports, essays, and federal and state reform proposals and reports; and secondary material, composed of summaries and reviews of the original reform reports and reports about effective programs that are based on reform recommendations. This annotated bibliography seeks to identify, briefly describe, and organize in a useful manner those publications dealing with K‐12 education reform and improvement. The overall purposes of this article are to bring organization to that list, and also to trace relationships and influences from the federal initiatives to the states and professional associations, and from there to the school districts and individual schools.

Explores the extent of employee surveillance in the western world and queries why the USA uses surveillance measures to a greater extent than other developed nations. Suggests that American managers choose surveillance methods which include the control of workers’ bodies in the production process. Lists the batteries of tests and monitoring to which US employees can now be subjected – including searching employee computer files, voice/e‐mail, monitoring telephone calls, drug tests, alcohol tests, criminal record checks, lie detector and handwriting tests. Notes also the companies which are opposed to worker and consumer privacy rights. Pinpoints the use of surveillance as a means to ensure that employees do not withold production. Reports that employees dislike monitoring and that it may adversely affect their performance and productivity. Argues that Americans like to address complex social problems with technological means, there are no data protection laws in the USA, and that these two factors, combined with the “employment‐at‐will” doctrine, have all contributed to make it possible (and easy) for employers to use technological surveillance of their workforce. Outlines some of the ways employers insist on the purification of workers’ bodies.
