An analysis of intermarket sales inflows/outflows within a shift-share framework

This article describes a method to analyse retail trade flows among competing retail centres. A case study of three nearby communities in the Southeastern United States is used to demonstrate the application of the technique. Results of the case study and their implications are discussed.     

Accounting for the Apple Inc business model: Corporate value capture and dysfunctional economic and social consequences

In this special issue the authors account for the Apple Inc innovative business model in terms of its capacity to create and capture value from its global supply chain. The authors argue that there are a number of reasons why the Apple business model may not be sustainable and more broadly explore the dysfunctional social and economic aspects of corporate behavior that seeks to fragment and elongate global value chains to capture value within the firms financial reporting boundary whilst displacing cost and risk.     

Structural analysis of international trade: Environmental impacts of Norway

Final demand purchases initiate production processes that ultimately lead to environmental impacts. With the increase in international trade, many production processes occur outside of the country of final consumption. Whilst several studies have evaluated the pollution embodied in consumption and trade flows, few studies have investigated the structural linkages between domestic consumption and production in foreign regions. In this article we apply three complementary approaches to study the production network leading from the Norwegian economy to domestic and international environmental impacts: (1) the consumption perspective identifies final demand purchases that produce environmental impacts; (2) the production perspective identifies the production processes generating the pollution for a given demand; and (3) structural path analysis is used to provide the linkages between the global production networks linking consumption and production. We find that the three approaches provide different, but complementary information. For policy to focus on both sustainable consumption and production, all three approaches are required to fully identify environmentally important sectors in an economy.     

Duration of share repurchase programs and firm performance

It is widely known that under asymmetric information, share repurchasss can be used by firms to signal firm quality. In this paper, it is shown that the duration of share repurchase programs can signal the degree of firm quality. The model predicts that the highest quality firms repurchase a fraction of their shares outstanding over a short duration, medium quality firms repurchase the same fraction over a longer duration, and low quality firms do not repurchase shares at all. An empirical investigation of firms that engage in repurchase activity supports the model.     

The Social Welfare Loss from Egg and Poultry Marketing Boards, Revisited

Continuing conflict over supply management warrants another look at its costs. The authors' model combines the traditional welfare triangle with the social welfare loss created when farmers bear the investment risk associated with possible termination of quota protection. The annual net social welfare loss from egg and poultry marketing boards likely exceeds $100 million, with consumers losing more than $500 million. Half the net social welfare loss is the cost of risk bearing. Quota prices imply that farmers expect quota lives to be relatively short. Therefore, changing to short fixed terms might halve the social welfare loss without imposing capital losses on farmers and might facilitate a return to a free market or auctioning new fixed term quotas.     

Synthetic diamond developments: perspectives from technology analysis

Synthetic diamond technology appears to have the capability of significantly changing the future technological landscape. Accordingly, The Institute for the Management of Technology regards it as a 'marker' technology. This paper suggests that there is a need to review expectations concerning synthetic diamond developments. Technology analysis is used as a method to understand and communicate the expectations. The history trends and applications are presented. Two challenges are revealed: First, High Pressure and High Temperature is being challenged by Chemical Vapour Deposition as the dominant manufacturing technology, suggesting that the latter should be monitored for breakthroughs. Second, the distinction between synthetic and natural gems is becoming harder to determine. This threat to the gem industry, in combination with the expanding industrial use, suggests that efforts should be pursued to establish the uniqueness of natural gems and to prevent the name 'diamond' from being ubiquitously used.
