In a model of an economy where land is modelled explicitly as heterogeneous subsets of the plane and utility takes an integral form, demand can be characterized as a specific map from endowments and prices into subsets of the plane. A modified form of the Neyman-Pearson lemma is used to obtain this result, the modification being necessary because the analog of randomized tests must be excluded from this model.  相似文献

Britain needs a complete transformation of its policy towards monopoly. Robert Miller argues that freedom of entry is the vital ingredient of policy for regulating monopolies and public utilities.  相似文献

There are some aspects of the European RFEC and its implementation today that could benefit from increased harmonisation; there are others in which substantial accommodation to local, national or regional circumstances and preferences is desirable or required.  相似文献

This paper develops a unified framework to analyze the dynamics of firm investment in countries with poor legal enforcement. The firm's technology edge over the government generates endogenous property rights. Industry variation in the technology gap predicts a sectoral pecking-order of expropriations. Long-run investment distortions may be Pareto superior relative to persistent investment at the static optimum. The dynamics of investment and transfers depend on whether incentives (backloading) or efficiency (frontloading) concerns dominate at the initial division of surplus. An increase in government efficiency may reduce its welfare. The model provides a technology-driven rationale for the widespread use of conglomerate structures in emerging market countries.  相似文献

This study uses a transactional model of stress and coping as a way to understand how outdoor recreationists deal with negative setting elements during a recreation experience. Within the transactional model, coping behaviors can be viewed as the result of on-going transactions among personal and environmental factors, perceptions of threat or stress, and the perceived effectiveness of coping strategies. The current study focuses specifically on the relationship between reported levels of stress and the types of coping strategies used by recreationists in Glacier National Park. Findings suggest that certain behavioral and cognitive coping responses to stress are associated with different levels of reported stress. Specifically, respondents with lower levels of stress were more likely to engage in certain cognitive adjustments to cope with detracting situations. Respondents reporting higher levels of stress were more likely to engage in either direct action aimed at changing the environmental conditions or are displaced entirely from the recreational setting. In addition to these primary findings, the study discusses the range of coping behaviors employed.  相似文献
