We explore a new argument that seeks to explain the near absence of the labor-managed firm or cooperative, despite a range of inefficiencies attributed to the present-day capitalist firm. We derive the crucial condition for the emergence of labor-managed firms and show that it is unduly restrictive from an efficiency point of view. The policy implication is that public intervention to promote labor-managed firms should primarily be in the form of start-up subsidies rather than in providing permanent tax subsidies.  相似文献

Since public networks became widespread, doubts have arisen over how to make them succeed. Scholars have traditionally addressed the issue in different ways, thus variously shedding light on the network structure, mechanisms, or managers as predictors of the network performance. The aim of our article is to explore the possibility of an interaction effect between the abovementioned factors. Our results show that there may be a relationship between network structure, mechanisms, and managers that jointly affects network performance. Therefore, important suggestions can be made about how to manage public networks successfully: (1) ensure that your network mechanisms and managerial abilities are coherent with the structure of your network; and (2) if you are in a well-established and integrated network, allow yourself some flexibility. Data were collected through a multiple case study that focused on collaboration for joint provision of home care services in Switzerland.  相似文献

More diverse, perennial cropping systems often have better natural mechanisms for keeping pests at bay. But while scientists emphasise the broad benefits of conservation in terms of effective ecosystem functioning, farmers are more interested in biodiversity for the provision of food or of services such as shade or windbreaks. Because of their limited knowledge of the role of biodiversity in plant protection, farmers sometimes unconsciously disturb natural regulatory mechanisms. Some citrus farmers in Vietnam introduced sapodilla as an intercrop to diversify their source of income, and because this fruit tree requires little care. However, this apparently worthwhile attempt to combine two valuable crops has misfired. The ecological conditions that traditionally sustained natural pest control in citrus have been disturbed, thus trapping farmers in the pesticide treadmill. The weaver ant Oecophylla smaragdina stopped protecting citrus from stinkbugs and leaf-feeding caterpillars after facing competition from the black ant Dolichoderus thoracicus, which favours sapodilla trees as a nesting habitat. To avoid similar scenarios in the future, methods for linking scientific research on ecosystem functions with farmers' own knowledge, experience and priorities are presented. Examples are given of ways in which farmers in perennial cropping systems learn, and how scientists can facilitate this learning process.  相似文献

This article describes the development of an instrument to measure the quality of managerial learning on the job. The instrument can be used to analyse the quality of the individual learning process on the job. The literature shows that two factors determine the quality of the learning process: the learning potential of the job context and the way in which the manager approaches their work. So the instrument has two components. The first component measures the four types of work experience that offer potential opportunities for individual learning. These are transitions, task-related characteristics, obstacles and support. The second component, the so-called learning behaviour, analyses the way the individual approaches the potential learning opportunities present in the job. This can also be divided into four categories: emergent learning, planned learning, instruction-oriented learning and meaning-oriented learning. Based on these two components, an instrument has been developed to measure the quality of learning on the job. This has been shown to be valid and reliable in a sample of European managers.  相似文献

In this paper we revisit the Dutch disease paying particular attention to the role of specific factors of production and capital stock dynamics. The main insight is that if the natural resource rich windfall is substantial but not large enough for the country to become a rentier, capital goods must be produced at home and adjustment to natural resource windfall takes time. It takes time to build this home-grown capital. Specific factors are crucial to explain the dynamic responses of the real exchange rate, capital intensities and wages in response to a natural resource windfall. If a country is small and the windfall is large, it may be able to import capital and migrant labour in which case the Dutch disease can be avoided.  相似文献

Despite broad public support for wind energy in principle, windfarm developments are often met with local opposition. There is theoretical, case-based and anecdotal evidence to suggest that ‘the local’ is relevant for planning process outcomes, but the nature and extent of this relevance is not so clear. We embark on an initial exploration of local factors that, on aggregate, may be of relevance to planning outcomes of proposed windfarms in rural England. Applying a broad scanning approach we use an existing small area GIS dataset of 117 variables related to education, health, demography, employment and housing. We identify a number of strong associations, and discuss to what extent these make sense in the light of existing literature on environmental equity and social capital, or throw up questions for further study. Notwithstanding the methodological caveats of this explorative study, and the scope for more in-depth analysis, our findings suggests that beyond the myriad of individual planning cases, the emerging landscape of wind energy development in England is markedly uneven, and sometimes inequitable. Evidence of the latter emerges notably through the strong significance of local democratic deficit (i.e. low voter turn-out) as a predictor of a ‘positive’ planning outcome for windfarms and the further strengthening of predictive associations at the appeal stage.  相似文献

We construct a new data set of consumption and income data for the largest US metropolitan areas, and we show that the extent of risk-sharing between regions varies substantially over time. In times when US housing collateral is scarce nationally, regional consumption is about twice as sensitive to income shocks. We also document higher sensitivity in regions with lower housing collateral. Household-level borrowing frictions can explain this new stylized fact. When the value of housing relative to human wealth falls, loan collateral shrinks, borrowing (risk-sharing) declines, and the sensitivity of consumption to income increases. Our model aggregates heterogeneous, borrowing-constrained households into regions characterized by a common housing market. The resulting regional consumption patterns quantitatively match those in the data.  相似文献

Given a segmentation problem, marketers may be forced to consider the benefits of both general and product-specific life style segmentations. This study therefore explores the procedures and refinements associated with each approach and offers overall conclusions as to each one's efficacy.  相似文献
