This article addresses the societal and cultural aspects of bioreserves and environmental restoration programmes. It begins with a discussion of bioreserves, then uses the example of a Man and Biosphere (MAB) inspired study of the US Everglades to illustrate how land has been shaped historically by culture and technology. It then demonstrates how current conflicts of values and culture, from both inside and outside the region, from interest groups with both pragmatic and emotional stances, are determining the future of an environment—the Everglades. The article thereby shows how human values and perceptions impact on the development of a sustainable Everglades, using the findings of surveys and public meetings to highlight the interests of the competing communities, ethnic and interest groups involved. If bioreserves are to survive they cannot become alienated from the people in the regions in which they are located. 相似文献

Summary We show that in a production economy with public goods and a measure space of agents an allocation belongs to the core of the economy if and only if there exists no allocation in the core of a subeconomy that blocks it.We are indebted to Yossi Greenberg for very helpful suggestions, especially concerning the introduction of this work. We would also like to thank the referee for useful suggestions. Part of this work was done while the authors were visiting CORE, Université Catholique de Louvain. The support of CORE is gratefully acknowledged. 相似文献

This article is an attempt to evaluate the relative effect of sociological and economic factors on economic performance of occidental and oriental family farm operators in Israel. Unusual circumstances prevail in Israel, where farm operators with modern and traditional backgrounds co-exist within a modern economy. This setting allows us to evaluate the effect of the human factor under conditions of relative independence from the organizational set-up. Economic performance has been found to be closely associated with the level of formal schooling, status of women, degree of literacy and family size. 相似文献

We show that the least core of a TU coalitional game with a finite set of players is contained in the Mas-Colell bargaining set. This result is extended to games with a measurable space of players in which the worth of the grand coalition is at least that of any other coalition in the game. As a consequence, we obtain an existence theorem for the Mas-Colell bargaining set in TU games with a measurable space of players. Journal of Economic Literature Classification Number: C71. 相似文献

We consider a Radner-type (e.g., Radner, 1968, Econometrica36, 31–58) pure exchange economy with differential information and a continuum of agents. We show that under appropriate assumptions the set of Aumann–Shapley private value allocations in such an economy coincides with the set of Radner competitive equilibrium allocations.

This paper provides a non-cooperative interpretation for bargaining sets concepts in economic environments. We investigate
the implementability of the Aumann-Maschler and Mas-Colell bargaining sets, and provide mechanisms whose subgame perfect equilibrium
outcomes realize these sets. These mechanisms, in contrast to general mechanisms suggested in the implementation literature,
have a natural structure closely related to that of the rationale underlying the bargaining sets. Furthermore, the strategy
sets consist mainly of allocations and coalitions (thus avoiding any reference to preference parameters) and are finite dimensional.

This paper contributes to a growing strand of literature on the determinants of tax revenue performance in developing countries, particularly in Sub‐Saharan Africa. More specifically we estimate the tax elasticities of sectoral output growth and public expenditure. The unique features of this paper are twofold: First, we develop a simple analytical model for tax revenue performance taking into account some structural features pervasive in most developing countries with large informal sectors. Second, we test the model predictions on Ugandan time series data using ARDL bounds testing techniques. Results indicate that dominance of the agricultural and informal sectors pose the largest impediments to tax revenue performance. In addition development expenditures, trade openness, and industrial sector growth are positively associated with tax revenue performance. We propose policies to support the development of value added linkages between agricultural and industrial sectors while emphasizing the need to unlock the potentially large contributions of the informal sector with a view of widening the tax base. 相似文献

Summary. We study the core and competitive allocations in exchange economies with a continuum of traders and differential information.
We show that if the economy is “irreducible”, then a competitive equilibrium, in the sense of Radner (1968, 1982), exists.
Moreover, the set of competitive equilibrium allocations coincides with the “private core” (Yannelis, 1991). We also show
that the “weak fine core” of an economy coincides with the set of competitive allocations of an associated symmetric information
economy in which the traders information is the joint information of all the traders in the original economy.
