Taking a positive approach to organizational downsizing

We drew from the literature on positive organizational behaviour (Luthans & Youssef, 2007) to test a process model relating generalized optimism (Carver & Scheier, 1999) to the cognitions, affect, and behaviour of 237 Canadian federal government managers during and following a major organizational downsizing. Our data supported a model in which generalized optimism measured 18 months prior to the downsizing (T1) associated positively with managers' cognitions, attitudes, job performance, and self‐reported coping effectiveness measured 12 months postdownsizing (T3). Analyses suggested that some of these associations were partially mediated by a positive thinking coping strategy and expectations for future career and job success reported during the downsizing (T2). We advocate for more research that draws from the positive organizational behaviour literature to study the effects of downsizing on survivors. Copyright © 2008 ASAC.

Impact of government R&D spending and the bifurcating labor market on high technology and higher education

In the past decade the social effects of technological change have contributed to the increasing bifurcations in the economy and the occupational structure. These changes, taken together with the consequences of governmental research and development spending patterns and the structural changes taking place at higher educational institutions, have implications for higher education policy making in the 1990s and beyond that are too important to minimize or ignore any longer. This paper demonstrates how the academic community can enhance its income, status, and effectiveness in society by responding to the effects of technological change, and offers some strategies for coping with changing skill requirements and industry-university partnerships.     

Goodness of fit for seemingly unrelated regressions: Glahn's R2y.x and Hooper's r̄2

This paper presents a measure of goodness of fit for Zellner's seemingly unrelated regressions. The measure is a monotonic transform of the appropriate (asymptotic) F-statistic, is bounded on [0, 1] and is maximized by Zellner's estimation technique. Glahn's composite correlation coefficient is shown to be a special case of this measure. It is also compared to Hooper's squared trace correlation coefficient. All three measures as well as some additional asymptotic summary test statistics are calculated for the two-equation example of Zellner. The applicability of the latter test statistics seems not to be recognized in applied work.     

The residual market factor,the APT,and mean-variance efficiency

The rapidly increasing volume of both published and unpublished work on the arbitrage pricing theory (APT) of Ross (1976) has given rise to a number of misunderstandings at the interface of theoretical and econometric work. In this article we extend the theoretical structure of our previous work (McElroy and Burmeister, 1985, 1988; Burmeister and McElroy, 1987, 1988) to provide a broad yet rigorous framework both for econometric estimation and for better economic interpretation of new empirical results. We begin with the case where allK factors are observed, and then present the second case ofK−1≡J observed APT factors and one unobserved factor, theresidual market factor introduced in McElroy and Burmeister (1985). The economic interpretations for equivalent specifications of this model are discussed, and we enumerate several immediate payoffs to these specifications. The main new results are concerned with the sometimes intricate relationships among APT models withK factors and APT models withK factors that are constrained to satisfy mean-variance efficiency restrictions. These results are not only of theoretical interest, but more importantly they provide the basis for econometric estimation and testing of nested hypotheses. These econometric issues are discussed in detail.     

Managing the planning process: A field study of the human side of planning

This paper reports the findings of an empirical field study of human behaviour in the context of planning. The investigation centres on ‘behavioural problems’ encountered by managers of strategic planning systems. Two general issues are addressed. The first concerns the frequency of occurrence of these problems among managers and their impact on the effectiveness of the planning process. The second issue pertains to whether the constellation of behavioural problems managers confront varies in accordance with the role of the manager in the planning system. Implications of the findings for practitioners and researchers are discussed.     

Weaker MSE criteria and tests for linear restrictions in regression models with non-spherical disturbances

This paper extend, in an asymptotic sense, the strong and the weaker mean square error criteria and corresponding tests to linear models with non-spherical disturbances where the error covariance matrix is unknown but a consistent estimator for it is available. The mean square error tests of Toro-Vizcorrondo and Wallace (1968) and Wallace (1972) test for the superiority of restricted over unrestricted linear estimators in a least squares context. This generalization of these tests makes them available for use with GLS, Zellner's SUR, 2SLS, 3SLS, tests of over identification, and so forth.
