Abstract: The term “neoliberalism” has come to be used in a wide variety of partly overlapping and partly contradictory ways. This essay seeks to clarify some of the analytical and political work that the term does in its different usages. It then goes on to suggest that making an analytical distinction between neoliberal “arts of government” and the class‐based ideological “project” of neoliberalism can allow us to identify some surprising (and perhaps hopeful) new forms of politics that illustrate how fundamentally polyvalent neoliberal mechanisms of government can be. A range of empirical examples are discussed, mostly coming from my recent work on social policy and anti‐poverty politics in southern Africa.  相似文献

A problem which has arisen in discussions of an elm-disease explanation for the Neolithic elm decline has been the lack of fossil records of Scolytus scolytus (F.) (elm bark beetle), which is the main carrier of the fungus which causes the present epidemic of Dutch Elm Disease. Now, the discovery of wing cases of two individuals from elm decline deposits at Hampstead Heath, London, proves that the beetle was present in Britain during this episode. The deposits in which it occurs are described, and the various implications for elm disease causing, aiding or at least occurring during this stage of the early Neolithic are discussed.  相似文献

ABSTRACT. This paper examines the RAS, Mc Menamin and Haring, and Lagrange-multiplier update methods in the context of the dual accounting system of the rectangular input-output model. The motivation was to determine if the additional information contained in the dual system is exploitable, while maintaining the integrity of the rectangular structure with all its advantages. Tests were conducted on the performance of the various algorithms for a derivative Leontief model relative to their performance on the rectangular structure. The results obtained for rectangular tables were generally better than those obtained for the more conventional Leontief ones.  相似文献

Results of a combined archaeological and analytical project of Late Neolithic/Early Bronze Age copper, bronze and lead artefacts from four distinct areas of mainland Greece are presented. The aim of the study is to understand better the stages of technological development of each region, their possible ore sources and also to assess any external contribution to or internal evolution of their metallurgy. Interesting results which could challenge the established view of Late Neolithic/Early Bronze Age metallurgy in the Greek mainland are presented.  相似文献

ABSTRACT. This paper uses a two-stage hedonic wage approach to derive the benefits from improvement of five cultural amenities. It is argued that the hedonic approach permits valuation of both private and local public aspects of cultural goods since access to the amenity is an essential input in the production of the final service flow. Empirical estimates of willingness to pay suggest price and income elasticities are approximately unity. Lower-bound estimates of marginal benefits for a representative city range from $0.85 million for an additional theater to $57.9 million for an additional zoo facility.  相似文献

"This paper presents a two-sector dynamic model of regional population change. The model contains a migration equation, an earnings equation, and an amenity equation for each region. In the context of this model, migration is seen as a disequilibrium process through which the regional populations move towards equilibrium positions. Migration occurs when one region is perceived to be superior to the other on the basis of its earnings and amenity levels. Equilibrium is achieved when population movements between the regions eliminate any differences in their relative attractiveness. A comparative-static analysis of the model is presented to analyze the effects of policy changes and exogenous shocks on the distribution of population among the regions." The geographical focus is on the United States.  相似文献
