Repositioning the urban environment question in Zimbabwe: a review of the context,conditions and processes

This analysis is a reappraisal of two perspectives in urban development in Zimbabwe: environmental sustainability and human sustenance. The discussion seeks to reposition the conservation–survival debate by broadening it to the wider urban and national macroeconomic and sociopolitical context. It re‐examines Zimbabwe's environmental problems by examining the challenges posed by urbanisation, industrialisation and informalisation. To these ‘permanent’ strands are added the ‘transient’ phenomena of structural adjustment and indigenisation. The analysis is done within the overall national macroeconomic and sociopolitical environment. The article examines environmental sustainability and human sustenance as the two policy challenges that have to be reconciled in the quest for sustainable urban settlements in Zimbabwe. The analysis stresses that the exercise of striking a balance between the needs of humankind and those of nature has to take cognisance of the complexity of issues and the processes going on elsewhere in the urban and national context.     

Biotechnology: the emerging battlefield for US and Japanese pharmaceutical companies

The Japanese pharmaceutical industry has lagged behind the US in developing and marhting innovative new compounh. A gap anabsis rebing on international publication and patenting stahtics as well as market survgs shows that the US is the clear leader in biophannaceuticals. Recent Japanese public and private efforts to close the gap have posed no immediate threat to US pharmaceutical companies. The conflict over industrial policy among the ministries involved will take some time to be resolved. However, information networking activities and cross-border technology linkages of Japanese companies should not be underestimated. Biotechnology is current4 transforming theJapanese pharmaceutical induse, and the US will have to deal with a gowing Japanese challenge in the long run. Preventive US counter-measures should include investments in in-house biotechnology research, acquisitions of smaller biotechnology start-up ventures, global commercialization o f biophannaceuticals, and proactive management o f technology linkages with Japanese companies.     

Does success diminish competitive responsiveness? Reconciling conflicting perspectives

Previous research provides conflicting evidence of the association between the past performance of a business and its competitive responsiveness, with researchers observing both positive and negative relationships. To clarify this issue, the authors test a model using survey data from the retailing industry. The model delineates direct and indirect mediated paths through ability to respond, motivation to respond, and awareness of competitors’ actions to show how past performance can have both positive and negative influence on competitive responsiveness. However, the overall impact of past performance of an organization on its competitive responsiveness is positive. The implications of these findings for research, practice, and theory are discussed.

Manifestations of compulsiveness in the consumer-marketplace domain

The marketing literature exhibits a consistent lack of concern to recognize the distinct differences among the various possible manifestations of compulsiveness in the consumer-marketplace domain. The practice of using terms pertaining to different manifestations of compulsiveness synonymously, especially when the meaning of the term “compulsive behavior” is itself under debate, creates further semantic uncertainties that hinder typological endeavors in the budding area of abnormal or deviant consumer behavior. This article attempts to remove such uncertainties by elucidating and establishing the differences among the above manifestations.     

When haste makes sense: Cracking down on street markets for illicit drugs

This paper presents an analytical approach to the tactical question: ‘What level of enforcement over time allows one to eliminate a street market for illicit drugs while expanding the least possible total effort?’ The analysis is done in the context of Caulkins' model [6] which predicts the rate of change of dealers as a function of enforcement level and several market parameters. Our analysis suggests that the simple strategy of using the maximum available enforcement intensity until the market has been eliminated minimizes the total enforcement effort required.     

Modelling non-competitive behavior in commodity markets: A game theoretic approach

In this paper, we provide a coalitional alternative to the perfectly competitive and purely non-cooperative assumptions commonly employed in the modelling of commodity markets. These assumptions of perfect competition or pure non-cooperation are usually imposed exogenously without providing an economic basis for assuming why firms that could stand to gain by cooperating would not in fact do so. Three behavioral rules embodied in three different cooperative games are discussed in this paper and a methodology for predicting the coalition structures that would result from each of these is offered. By applying these games to the US copper industry of the 1970's, we show that the theory of games can be profitably employed in conjunction with the traditional institutional approach of industrial organization to yield useful economic predictions.The author is grateful to two anonymous referees whose comments led to a considerably improved version of the paper.
