During the past four decades, United States field crop production has been transformed by the mechanical and fertiliser revolutions. In this study crop-specific estimates of the technical progress parameters that represent these changes are used to test the microeconomic theory of induced innovation. Tests based on the land/labour ratio, derived from a reformulation of the Hayami and Ruttan model, entirely support the inducement hypothesis and suggest that the partial failure of previous empirical investigations resulted from specification problems. 相似文献

Abstract. Faced with divergent opinions among consumers on the use of genetically modified (GM) foods, Canada has adopted a voluntary labelling approach for non‐GM foods, whereas the European Union has a mandatory labelling policy for GM foods. Interestingly, both labelling systems have resulted in very little, if any, additional consumer choice. Using an analytical model, we show that the coexistence of GM and non‐GM products at the retail level depends on the labelling policy, consumer perceptions, and the type of product. Although voluntary labelling tends to favour the use of GM products, it is more likely to provide consumer choice. 相似文献

This paper is about rational sociality. Retaining rational choice as its basic framework, it aims to enrich it by taking seriously a well-established cultural, social and psychological phenomenon: that some inter-personal relationships have intrinsic value. These are termed primary. Utility maximisation includes the binary choice to enter or not to enter a primary relationship: this on the one hand has a direct impact on utility, and on the other imposes restrictions on consumption choices. The model encompasses standard economic choice theory as a special case, while explicitly recognising that self-interested agents make choices that are sometimes group dependent. The broad scope of this approach is illustrated by a number of extensions and applications, some of which lead to distinctly unorthodox conclusions. 相似文献

Using case‐study data, the article examines the contention that protective labour market policies and trade union action are responsible for growing divisions between labour market ‘insiders and outsiders’. Case studies are reported on developments in collective bargaining in the hospitals and engineering sectors from seven western and central European countries. The article finds that managerial strategies, and interactions between management and unions, have to be considered to give a full account of the growth of precarious employment. 相似文献

Business angel networks (BANs) provide a channel of communication between private venture capital investors (business angels) and entrepreneurs seeking risk capital. Most operate locally on a not-for-profit basis with their costs underwritten by the public sector. However, the recent establishment of BANs by private sector organisations in the U.K. has led to a questioning of the government's continuing role in the financing of BANs. This paper demonstrates that there are significant differences between public sector and other not-for-profit BANs and private sector, commercially-oriented BANs in terms of the investments that they facilitate. Private sector BANs are primarily involved with larger, later stage deals whereas investments made through not-for-profit BANs are generally smaller, involve start-ups and other early stage businesses and are local. The emergence of private sector BANs has therefore not eliminated the need for public sector support for locally-oriented networks. 相似文献
