Migration from the mountain areas of pre-industrial Europe has been seen as the product of poverty. While hardship controlled the strategies of the more marginalized households, better placed families used their migration experience to establish themselves in commerce. Over generations they used contacts and kinship systems to develop important informal trading networks. It is difficult to establish the effects of this hidden activity on local mountain economies, but dowry payments and post mortem inventories are used to expose the impact of inflowing capital and its circulation. 相似文献

Planning food services for a campus setting 总被引:1,自引:0,他引:1
Kenneth J. Klassen Elzbieta Trybus Arundhati Kumar 《International Journal of Hospitality Management》2005,24(4):579-609
Providing appropriate food services in a campus setting is increasingly important due to more demanding customers and because clients have less time to go off-campus when they need to eat. Using a university campus as an example, this research looks at customer satisfaction with existing food services and explores various methods for determining where to locate new facilities. This campus currently has great needs for additional food services, and it is shown clearly where additional food services are required. Also, the methods used are compared in terms of their effectiveness in finding the solution. 相似文献

Supply chain management (SCM) is implemented by integrating corporate functions using business processes within and across companies. Several process‐oriented frameworks for SCM have been proposed but only two of these provide sufficient detail to enable implementation. We evaluate the Supply‐Chain Operations Reference (SCOR) framework and The Global Supply Chain Forum (GSCF) framework using four criteria and identify their relative strengths and weaknesses. 相似文献

This paper provides some new evidence on the behaviour of cross-country growth rates. We reject the linear model commonly used to study cross-country growth behaviour in favour of a multiple regime alternative in which different economies obey different linear models when grouped according to initial conditions. Further, the marginal product of capital is shown to vary with the level of economic development. These results are consistent with growth models which exhibit multiple steady states. Our results call into question inferences that have been made in favour of the convergence hypothesis and further suggest that the explanatory power of the Solow growth model may be enhanced with a theory of aggregate production function differences. 相似文献

Steven R. Tabor 《Bulletin of Indonesian Economic Studies》1989,25(2):31-51
Aggregate agricultural commodity demand parameters are estimated, based on an application of the Deaton and Muellbauer Almost Ideal Demand System to a seventeen year Indonesian time-series data set of prices, expenditures and consumption availability. The statistical results are generally significant and correctly signed. The revealed demand relationships imply that the Indonesian food Staples are normal goods. Expenditure elasticities are higher for the higher value foodstuffs than for the lower value starchy staples. Furthermore, the demand for rice has become highly inelastic to both own and cross-price interventions. This implies that rice price interventions will require a high degree of fine-tuning in order to stabilise prices effectively, and that low urban rice prices cannot be regarded as an appropriate, or even second best policy instrument for improving nutritional status.
A high degree of Substitution between rice and secondary food crops, and amongst groups of secondary food crops, is identified. The significance of the cross-price elasticities for the secondary food crops suggests that single-market interventions will have non-trivial budget-mediated effects in other commodity markets. The management of a multi-commodity food policy requires that the spillover effects from commodity pricing policy must be taken into account in order to optimise the effects of price policy interventions. 相似文献

Employment,schooling and productivity growth 总被引:1,自引:1,他引:0
Summary This paper presents an empirical analysis of labour demand and labour productivity growth in The Netherlands. Assuming an aggregate production function with as factors capital and 3 types of labour, distinguished by educational attainment, cost minimization leads to a set of 3 labour demand relations to be estimated on time series data. Using the estimates and the implied elasticities, aggregate labour productivity growth is decomposed into factor substitution, autonomous factors, labour time shortening, economies of scale, utilization rates and the increased educational level of the working population. The contributions of substitution, utilization rates and education appear to be substantial, notably in the seventies.
