A refined consumption-wealth ratio and its role on time-varying consumption risk

This paper takes a deeper look at the measurement of the consumption-wealth ratio and analyzes its ability to capture variations in expected future stock returns. I find evidence of stock return predictability by taking a different approach than predictive regressions.     

THE IMPACT OF THE PRODUCT/PRODUCTION PROCESS INTERACTION ON THE EVOLUTION OF STRATEGIC RESPONSE

This article synthesizes previous research on the interaction between product and production process, and the impact of that interaction on the evolution of strategic response. This interaction has major implications for the competitiveness and productivity of the firm. The authors identify characteristics of the interaction that allow a more complete analysis of its relation to firm strategic response, productivity and competitiveness.     

Automating the computation of solutions of large economic models

The computer implementation of any large economic model is usually a very expensive and time consuming task. This paper describes a software package, called GEMPACK, which is being developed specifically to reduce dramatically the research time, effort and cost required to set up one solution method (the Johansen method) on an actual computer. Existing features of GEMPACK are described in detail, as are developments planned for the near future. The software is model-independent, in that it works for a wide class of economic models, irrespective of the form of the equations or underlying theory. GEMPACK is portable to most mini and mainframe computers, because it has been written in ANSI standard FORTRAN 77, with such portability as a primary requirement. Several models, including the Dervis, de Melo and Robinson model of Korea, have been implemented using GEMPACK.     

The non‐professionally affiliated (NPA) worker as co‐producer of public services: how is the role experienced in UK mental health services?

Recent workforce reforms have led to the widespread expansion of non‐professionally affiliated (NPA) support and assistant roles within UK public services. Research into these roles has been confined to a limited range of settings, with a focus on the consequence of change for professional workers. This article explores the emergence of ‘co‐production’, whereby NPA workers contribute alongside the professional in a distinct, complementary way. Findings are drawn from semi‐structured interviews with frontline workers and managers within the context of mental health workforce reform. The results build a picture of NPA working life characterised in part by autonomy and responsibility. At the same time, NPA workers rely on colleagues for support and are subject to being used indirectly by professionals. Contextual influences are considered. The conceptual implications of the analysis are brought out, both for the NPA role itself and for the broader issues involved in front line service work.     

Mending the family tree a reconciliation of the linearization and levels schools of AGE modelling

This paper offers a critical comparison between the North American levels school of applied general equilibrium modelling, and the Norwegian/Australian school of linearizers. The paper develops both the levels and linearized representations of a neoclassical multiregion trade model. This is used as a vehicle for focusing attention on similarities and differences between the two schools. The main conclusions are: (i) that both the levels and linearized versions of non-linear AGE model offer a valid starting point for obtaining accurate solutions to the non-linear equilibrium problem; (ii) when update formulae are not employed, linearized representations are particularly prone to erroneous welfare conclusions; (iii) the levels representation offers a more natural starting point for expressing accounting conditions, whereas behavioural relationships are relatively more easily expressed in a linearized representation. Recent software developments now make both approaches to the representation and solution of non-linear AGE models convenient to implement. Thus the choice of which approach to use will depend on the special needs and preferences of the economist implementing the model. The two traditions of AGE modelling have a great deal in common and both would benefit from greater cooperation.     

Unionization,Compensation, and Voice Effects on Quits and Retention

This study explores the relationships among unionization, compensation practices, and employee attachment (quit rates and tenure) among trucking companies to assess the applicability of Freeman and Medoff's exit/voice argument. Unionization was associated with lower quit rates, higher tenure, a better compensation package, and stronger voice mechanisms. The relationship of unionization to quit rates and tenure becomes nonsignificant after accounting for compensation (pay and benefits), and voice mechanisms do not add explanatory variance.     

Extending Business Education Beyond Traditional Boundaries: A Case Study in Negotiated Problem Resolution in a Remote Regional Indigenous Community in Australia

It is widely accepted that the concepts and practices of management can only be of benefit when they are anchored to the contextual architecture of people, processes, structures, and technologies. The challenge of establishing a bridging program for providing managerial competencies to Australian Indigenous people has become a serious one for multinational mining companies. As the wings of globalization interact with the long-ignored reality of marginalized local milieu, a need for an innovative management education system has become a major imperative compelling multinational mining companies to work collaboratively with the government, educational institutions, and Indigenous communities. The article outlines a specific decision-making dilemma in an Indigenous context, while explaining the imperatives for educators, who have the challenging task of instructing potential graduates how to manage the unique contextuality of rural Australian Aboriginal communities. The article presents implications for large-scale modern multinationals as they move to geographically remote regions of the world where large number of marginalized local people need to be drawn into the workforce not only as an act of a social responsibility imperative, but also as sound business pragmatism.
