The purpose of this study is to build on the results recently obtained by Poznanski (1990). First, the estimation technique is generalised by removing both the symmetric restrictions and the effects of autocorrelated errors that are present in simple logistic functions. Secondly, attention is drawn to the existence and consequences of multicollinearity when non linear techniques are applied to a general exponential. Thirdly, an attempt is made to quantify the importance of market structure and time lags in adoption as determinants of diffusion speed. Finally, a comparison between these generalised results and Poznanski's is made.The study concludes that, by generalising the estimation technique, some significant changes take place. Changes occur in the ordering and magnitude of diffusion speeds, especially amongst the developing and centrally planned economies. Changes also occur in the nature of the diffusion process, and in the importance attributed to market structure and diffusion lags in determining the rate of diffusion. It is also shown that, for some countries, multicollinearity imposes constraints on the type of generality that can be obtained. 相似文献

Summary. This paper defines and studies optimality in a dynamic stochastic economy with finitely lived agents, and investigates the
optimality properties of an equilibrium with or without sequentially complete markets. Various Pareto optimality concepts
are considered, including interim and ex ante optimality. We show that, at an equilibrium with a productive asset (land) and sequentially complete markets, the intervention
of a government may be justified, but only to improve risk sharing between generations. If markets are incomplete, constrained
interim optimality is investigated in two-period lived OLG economies. We extend the optimality properties of an equilibrium with
land and give conditions under which introducing a pay-as-you-go system at an equilibrium would not lead to any Pareto improvement.

At present, our society and its social security system are not prepared to cope with the challenges resulting from the continuous increase of life expectancy. The traditional concept of disease has to be modified for serving the special needs of the elderly. The optimistic compression of disease theory is an intriguing model, but lacks prove by available data. The anti-aging boom diverts the focus from the social and financial burden that will be unevitably caused by long-term care in the future. If there will not be an — up to now unforeseeable — breakthrough in research, particularly dementia will have an enormous impact on social cost which is often underestimated. 相似文献

Some 'real' problems of 'virtual' organisation 总被引:1,自引:0,他引:1

This paper presents an ethnographic study of organisational change in a retail bank considering issues surrounding the supposed emergence of the 'virtual organisation'. It outlines emerging problems in organisational work as a consequence of the shift toward 'virtuality' and questions the explanatory value of such theoretical stances. 相似文献
