The common law doctrine of employment at will holds that, unlessspecified otherwise, the employment relationship can be terminatedfor any reason. Beginning in the mid-1970s, many state courtsbecame willing to find exceptions to this doctrine. A possiblebenefit of this new approach is that it provides a third-partyenforcement mechanism to implicit labor contracts. This articleuses two large micro data sets on employee tenure and wagesto evaluate the impact of exceptions to employment at will.Although the results suggest that exceptions to employment atwill affected labor markets, there is little evidence that exceptionshelped enforce implicit contracts.  相似文献

The continued existence and predominance of large farm enterprises (LFEs) in Russian agriculture during the transition to a market economy is analysed using theories of transaction costs, coordination mechanisms and networks. A comparative analysis is presented of farm restructuring in two, highly contrasting survey regions. That analysis shows that LFEs have undertaken only partial restructuring, which has not lead to radical increases in output and productivity. Still, LFEs have kept functioning by adopting a rational strategy of 'coping with the market'. This entails their integration into processing and retailing, and building up new business (and social) networks while cultivating old ones. The network economy that has thus emerged has enabled them to stay afloat as social and economic units, in a form of 'paradoxical continuity'.  相似文献

In this paper, results are introduced of an empirical study which investigated the practice of occupational health and safety regulation in two countries, Great Britain and West Germany. The analysis concentrates on the specific relationship that regulatory agencies and the concerned interest groups, employers and trade unions, develop in the two stages of policy formulation and implementation of health and safety regulation. Results show that interest groups actively participate in the regulation-making systems in both countries. Their policy pursued in this process is influenced and mediated by their actual resources as well as by individual views and assessments of each side's representatives. In Germany, a strong fragmentation with numerous private and quasi-governmental bodies entitled to formulate standards makes it difficult for the interest groups to concentrate on the competent and important committees. In contrast, we find a clearer responsibility of bodies and committees in the case of Britain. In both countries, enforcement policy prefers an advisory and persuasive style even though the legal backgrounds are quite different.  相似文献

Abstract: This paper deals with some important sources of confusion in discussions of urban issues. The first part distinguishes urban planning as a “future oriented” activity, from urban management which is primarily concerned with resource allocation. (The nature of urban development — interdependence and long life — makes a long-term perspective important.) When urban management aims to implement a plan the two are complementary. Urban policy covers a broader range of issues. The second part distinguishes four levels of debate about urban issues: ideological, political, operational and technical. Frequently debates in urban studies are not coherent because the participants are arguing at different levels and therefore make different assumptions about what is given and what can be varied. It is argued that the various levels form a hierarchy so that debates at any level need to assume particular positions with respect to higher level questions. Ideological issues include individual versus collective perspective, capitalist versus socialist, the appropriate role of markets and governments and the relative weight given to equity and efficiency criteria. The examples of political issues discussed are rationality versus group pressure as explanations of government behaviour, and whether planning is mainly a political or a professional activity. Operational issues include the appropriate level of government for carrying out urban functions and the role of statutory planning and other policy measures. Technical issues focus on predicting the effects of policy measures and external changes on cities. The different levels are illustrated by a discussion of policy towards inner city areas.  相似文献

Authors' Note: It is too early to provide a definitive view and appraisal of the Office of Management and Budget in the Reagan presidency. The discussion that follows is based partly on current and recent articles and a few recent monographs and books, many of which are credited in footnotes. In additon we have relied upon a considerable number of interviews with current participants and alumni of OMB as well as with some observers from outside. It would be impracticable to list those who helped us, but we are grateful to all of them. The substance of this article was completed in mid-July 1982.  相似文献
