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.     

Client loyalty and defection in the corporate legal industry

As the legal service industry matures and becomes saturated, more traditional forms of marketing may need to be replaced by the adoption of newer relationship concepts. This article reports on a research investigation among corporate clients of UK law firms. The findings reveal that satisfaction with the service is the key factor that influences corporate clients to stay loyal to a particular law firm. The quality of legal advice, trust and honesty were also found to be important factors that drive client loyalty. Conversely, poor quality, as an outcome of the client – legal firm interaction, is perceived to be a significant contributor of client defection. Overall, the findings emphasise the need for legal firms to focus on client retention for survival and profitability.     

Use of pharmaceutical manufacturers'' value-added services to build customer loyalty

Maximum difference conjoint analysis is used to determine which value-added services offered by pharmaceutical manufacturers are liked the best (worst) as perceived by hospital pharmacy directors. When pharmacy directors are presented with opportunities to switch biotechnological products, it is possible to assess the relative value of value-added services in maintaining customer loyalty. A manufacturer's resources, such as educational programs, product services, and other specialized skills, are valued by hospital pharmacy directors as revealed by their reluctance to switch to a competitor's product. Differential effects of hospital size and managerial implications are also discussed.     

Relationship Marketing and Sustained Competitive Advantage

This paper examines four perspectives of relationshipmarketing that have been discussed in the marketing literaturein recent years and which are being touted as sources of long-termprofitability for organizations. We examine each of the fourperspectives (locking in customers, customer retention, databasemarketing, and building strong, close, positive relationships)to assess their potential for achieving a sustained competitiveadvantage. Our analysis suggests that only those organizationsthat build strong, close, positive relationships with their customershave the potential to develop a sustained competitive advantagethat may lead to above normal performance.     

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.
