Understanding Supermarket Competition Using Choice Maps

In this paper we propose a model which combines the spatial interaction models with the latest developments in internal market structure analysis and allows us to infer supermarket competition from revealed preference data. Using a nested logit formulation we model consumers' store choice decisions to be a two stage process in which consumers choose first the suburb and then the store from which to buy groceries. Hence, our method allows retail managers not only to understand the advantage (or disadvantage) of having their store chain in a particular area but also assess the competition within that area. Comparisons to Factor Analytic Choice Map is made.     

Why money meanings matter in decisions to donate time and money

Most charitable organizations cannot accomplish their missions without asking for money. This is paradoxical because recent research suggests that mentioning money primes a self-sufficient mindset, thus undermining the very behaviors these organizations desire to elicit. We offer an important qualification to this problematic effect. We find that priming cash concepts reduces willingness to help others, while activating credit card concepts reverses these effects. To explain our findings, in three studies we show that priming cash concepts makes costs associated with donating time or money more salient in the decision context, thereby reducing willingness to give help and to receive it. However, priming credit card concepts makes the benefits of donation more salient.     

Evaluating Product‐Centric Continuous Improvements: Impact on Competitive Capabilities and Business Performance

Product‐centric continuous improvements (CIs) are actions via which firms modify the design of a product after the start of its production and release into the market. Product‐centric CIs are initiated to help build competitive capabilities and sustain competitive advantage throughout the product life cycle. This study complements the perspective pervasive in the extant literature that actions related to product‐centric CIs can be disruptive to firms and be associated with negative performance consequences. It investigates a topic that is relatively much less researched, namely the upside potential of product‐centric CIs. The empirical analysis is based on data collected from 144 plants in the United States representing process and discrete part manufacturing industries. Specifically, the study analyzes the impact of product‐centric CIs on competitive capabilities and business performance. The results of the empirical analysis indicate the following: First, there exist two categories of product‐centric CIs: (1) actions for quality improvement and (2) actions for cost reduction. Second, while there is a positive association between each type of CI and the intended competitive capability, there also is a trade‐off—i.e., actions for quality improvement increase quality capability but reduce cost capability, and vice versa. Third, there is a strong linkage between business performance and quality capability, but not cost capability. All in all, the study presents empirical evidence that product‐centric CIs have a significant impact on competitive capabilities related to quality and cost, and, in turn, have an impact on business performance. From the standpoint of practice, the study suggests that product‐centric CIs should be managed to develop competitive capabilities and improve business performance.     

Output variability and economic growth: The case of Australia

This paper looks at the relationship between output variability and economic growth in Australia using the ARCH-M model. Quarterly data for growth rates of industrial production and of GDP are used for the analyses. However, the growth of GDP does not show any ARCH effects. The variability is found to be significantly negatively related to the growth rate of industrial production. Unlike Caporale and McKiernan (1998), our empirical results do not support Black's (1987) hypothesis, which is that there is a positive relationship between output variability and economic growth. Our results support the Keynesian position. The authors thank the anonymous referee for helpful comments on an earlier draft of the paper.
