Separating the Wheat from the Chaff: FMS, Flexibility and Socio-organizational Constraints

In contrast to arguments that flexible manufacturing systems (FMS) are highly versatile configurations that are only prevented from machining a wide range of parts by extrinsic constraints, this article contends that FMS are a genre of configurations that combine flexibility and intrinsic constraints in a variety of permutations, depending on a user's intended objectives. Empirical evidence is used to identify the factors that shape the levels of constraint in particular FMS and to identify instances where intrinsic constraints impede performance. Suggestions are made for initiatives to facilitate the continued use of FMS with the highest levels of intrinsic constraints that have hitherto hindered performance when the FMS users' manufacturing needs changed. Occupational structures that promote a polarization between staff with engineering knowledge and those responsible for defining general strategic objectives are suggested as a potential obstacle to such initiatives.

Dynamic spatial autoregressive models with autoregressive and heteroskedastic disturbances

We propose a new class of models specifically tailored for spatiotemporal data analysis. To this end, we generalize the spatial autoregressive model with autoregressive and heteroskedastic disturbances, that is, SARAR(1, 1), by exploiting the recent advancements in score‐driven (SD) models typically used in time series econometrics. In particular, we allow for time‐varying spatial autoregressive coefficients as well as time‐varying regressor coefficients and cross‐sectional standard deviations. We report an extensive Monte Carlo simulation study in order to investigate the finite‐sample properties of the maximum likelihood estimator for the new class of models as well as its flexibility in explaining a misspecified dynamic spatial dependence process. The new proposed class of models is found to be economically preferred by rational investors through an application to portfolio optimization.     

An Empirical Note on the Influence of the US Stock Market on Australian Economic Activity

This paper empirically examines the impact of the US stock market on Australian economic activity as one explanation of the strong correlation in the Australian and US business cycles. It is found that both the US and Australian share markets appear to have a significant impact on Australian activity.     

Whom do you distrust and how much does it cost? An experiment on the measurement of trust

We advance the measurement of trust in economics in two ways. First, we highlight the importance of clearly identifying the target of trust, particularly for obtaining concordance between attitudinal and behavioral measures of trust. Second, we introduce a novel behavioral measure of (dis)trust, based on individuals? willingness to pay to avoid being vulnerable to the target of trust. We conduct an experiment in which we vary the target of trust among passersby at several locations around a city, measuring both behavioral distrust and trust attitudes towards these varying targets. We find that subjects discriminate based on perceived characteristics of different targets in determining whether to trust, in a manner consistent with trust elicited using attitudinal measures and with actual trustworthiness. Risk aversion and altruism do not correlate highly with our measure of distrust.     

Casemix Management in a New Zealand Hospital: Rationalisation and Resistance

This paper discusses the use of a 'casemix' information system to rationalise and scrutinise clinical activity in a corporatised New Zealand hospital. The implementation of the casemix system was part of a management strategy to influence clinician behaviour by making visible the financial implications of clinical decisions. Clinicians were able to resist the application of this comparative surveillance system by challenging or diverting the information produced.     

Influences on Sustainable Innovation Adoption: Evidence from Leadership in Energy and Environmental Design

The adoption of innovations associated with environmental sustainability has been a topic of growing interest among scholars. The research presented in this paper draws on Abrahamson's theoretical framework of fads and fashions to argue that dimensions of uncertainty and degree of external versus internal influence provide significant insights into firms' decisions to adopt sustainable building innovations. We develop three hypotheses, reflecting three views of adoption influence: fad, fashion, and efficient‐choice. We find that adoption of Leadership in Energy and Environmental Design (LEED) green building certification in the United States was more likely among firms similarly oriented toward end‐consumers and among firms strategically positioned as environmental leaders. These results provide support for the fad and efficient‐choice views of adoption, respectively. Contrary to expectations suggested by the fashion perspective, adoption was not more likely among firms located in states whose political leaders are more committed to environmental protection. Our findings offer important implications for practitioners and policy makers seeking to encourage sustainable building design. Copyright © 2011 John Wiley & Sons, Ltd and ERP Environment.     

Helping tomorrow's retirees manage "distribution phase" risks

Much of employers' attention has focused on helping employees manage the accumulation of 401(k) plan assets rather than on helping them manage the distribution phase--the period during which employees begin drawing down their 401(k) savings to meet their retirement needs. Assisting employees in managing the distribution phase can play an important role in helping employers meet a range of workforce planning goals and ensuring a maximum return on the retirement dollars that have been invested by both employees and the company. By implementing a properly structured approach to help employees manage the distribution phase, employers can help them maximize the value of their retirement savings at little or no employer cost, thanks to the leverage of the company's group purchasing power and the tax advantages of employer-sponsored plans.
