We investigate the impact of direct payments on agricultural commercialisation in Kosovo. Kosovo is one of the poorest countries in Europe but, with European assistance, provides substantial funds to support agriculture, made up of many small and often semi‐subsistence farms. Thus, the effect of this support is a central policy issue. Identifying the effect of direct payments on market participation faces endogeneity issues arising from the possible simultaneous determination of participation in support programmes and market participation. In order to achieve proper identification of the endogenous direct payments, we use a strategy of targeted identification search that employs several different methodological approaches. We find that direct payments for fruit and vegetables, and those for cereals and oilseeds have a positive effect on market participation. However, we cannot identify any definite effect of livestock payments.  相似文献

This article examines the demographic and geographical importance of wealthy middle-class women. It argues that in certain towns and cities, notably London, such women were of sufficient importance to merit attention in their own right. Drawing upon a sample of wills, it describes the types of wealth owned by these women. By examining women's investment in government securities, it argues that women's wealth was of crucial importance to the British state. Its findings challenge conventional understandings of the relationships between gender ideology, wealth holding, and economic development.  相似文献

A Global Ex-vessel Fish Price Database: Construction and Applications   总被引:2,自引:0,他引:2  
Synopsis We describe the first effort at creating a global ex-vessel fish price database, which is required for understanding the economic behavior of participants in the world’s fisheries. We demonstrate potential applications of the database by linking it to a spatially defined catch database, which makes it possible to attach landed values to species in both time and space. This is the first database available publicly where interested members of the public, researchers and managers can easily find and access ex-vessel prices of the world’s major commercial fish species. Preliminary results indicate that the average real price of a number of species have declined between 1950 and 2002. The estimated landed value of fish globally, in year 2000 dollars, was about US$24 billion in 1950. It increased steadily to about US$90 billion in the early 1970s, reached a peak of US$100 billion at the end of the 1980s, and declined to about US$80 billion in 2000. The top 15 fishing countries cumulatively account for 79% of total real landed value, with Japan leading, even though the value of its landings has been declining.   相似文献

This article compares performance management practices in call centres from four telecommunications firms in the United Kingdom, France, Denmark, and Germany. Findings show that different combinations of institutional constraints, such as strong job security protections, and participation resources supporting worker voice were influential in shaping choices among policies to motivate and discipline workers. Performance management most closely approached a high‐involvement model where both constraints and resources were high, where worker representatives were able both to restrict management's use of sanctions and to establish procedures that improved the perceived fairness of incentives. Findings contribute to debates concerning the role of contextual factors in the design and effectiveness of HRM.  相似文献

Despite the importance of market segmentation, the growth of the travel and tourism industry in Taiwan, and the repeat travel phenomenon in tourism, relatively few studies have examined the behavior of repeat travelers in the East Asia region. The present study was designed to fill this gap. This exploratory study applied multistage segmentation in the context of repeat travel behavior to Taiwan. It examined the socio-demographic profile, trip characteristics and expenditures of Taiwan inbound repeat travelers. The results indicated that nationality, income, type of travel arrangements and information search behavior significantly affected repeat travel behavior. In terms of travel expenditures, males spent significantly more than females. Those travelers between 40 and 60 years old tended to spend the most when they visited Taiwan compared to other groups. Chinese travelers were most likely to have traveled to Taiwan more than once among all nationalities compared in this study. Those from Korea and Japan spent the most money among all nationality groups. This study provided several significant implications for the marketers of tourism in Taiwan.  相似文献

In this paper, we make five contributions to the literature on information and entropy in generalized method of moments (GMM) estimation. First, we introduce the concept of the long run canonical correlations (LRCCs) between the true score vector and the moment function f(vt,θ0)f(vt,θ0) and show that they provide a metric for the information contained in the population moment condition E[f(vt,θ0)]=0E[f(vt,θ0)]=0. Second, we show that the entropy of the limiting distribution of the GMM estimator can be written in terms of these LRCCs. Third, motivated by the above results, we introduce an information criterion based on this entropy that can be used as a basis for moment selection. Fourth, we introduce the concept of nearly redundant moment conditions and use it to explore the connection between redundancy and weak identification. Fifth, we analyse the behaviour of the aforementioned entropy-based moment selection method in two scenarios of interest; these scenarios are: (i) nonlinear dynamic models where the parameter vector is identified by all the combinations of moment conditions considered; (ii) linear static models where the parameter vector may be weakly identified for some of the combinations considered. The first of these contributions rests on a generalized information equality that is proved in the paper, and may be of interest in its own right.  相似文献

This paper reports on a study of current practice in policy transfer, and ways in which its effectiveness can be increased. A literature review identifies important factors in examining the transfer of policies. Results of interviews in eleven cities in Northern Europe and North America investigate these factors further.The principal motivations for policy transfer were strategic need and curiosity. Local officials and politicians dominated the process of initiating policy transfer, and local officials were also the leading players in transferring experience.A range of information sources are used in the search process but human interaction was the most important source of learning for two main reasons. First, there is too much information available through the Internet and the search techniques are not seen to be wholly effective in identifying the necessary information. Secondly, the information available on websites, portals and even good practice guides is not seen to be of mixed quality with risks of focussing only on successful implementation and therefore subject to some bias. Officials therefore rely on their trusted networks of peers for lessons as here they can access the ‘real implementation’ story and the unwritten lessons. Organisations which have a culture that is supportive of learning from elsewhere had strong and broad networks of external contacts and resourced their development whilst others are more insular or inward looking and reluctant to invest in policy lessons from elsewhere. Solutions to the problems identified in the evidence base are proposed.City to city policy transfer is a very active process in the field of transport. Not enough is yet understood about its benefits or the conditions under which it is most effective. Such understandings should help to promote and accelerate the uptake of effective and well matched policies.  相似文献

Public policy towards youth employment and training in Britain during the past decade has been dominated by two themes: the quest to reduce youth relative pay, as part of a wider deregulation of the labour market, in order to increase access to jobs and training: and the neglect of apprenticeship in favour of the Youth Training Scheme. This paper analyses these policies in an institutional framework informed by the results of a recent research project on youth activity in industry in major EC economies (Marsden and Ryan 1986, 1988, 1989, 1991).
The policy debate in Britain has tended to focus upon the effectiveness of lower youth pay at improving youth access to jobs and training (Wells 1983; Jones 1985; Junankar and Neale 1987). We accept the efficacy of lower youth pay but question its institutional viability. Youth employment and training policies must be well grounded in labour market institutions in order to achieve success. We argue that neglect of the institutional context accounts for the lopsided and partial success resulting from current policies in Britain, and that the revitalization of apprenticeship, either as such or in the equivalent form of a strongly upgraded public training scheme, has a great deal to offer.
We begin with an outline of the relevant institutions. We trace their implications for outcomes in the youth market, contrast the divergent institutional directions taken by West Germany and the UK, and finally assess contemporary British policy towards youth activity in general and apprenticeship in particular.  相似文献
