Limited opportunities for crop switching and lengthy preharvesting periods make the plantation sector particularly vulnerable to climate change. Surprisingly, however, the economic consequences of climate change on plantation crops are seldom analysed. Drawing on a unique primary panel data set from a representative cross section of 35 tea estates in Sri Lanka over the period 2002–2014, this study implements a structural model of estate profit maximisation to estimate the elasticity of labour demand with respect to different components of weather. Results indicate a negative relationship between labour demand and rainfall in the south‐west monsoon, the north‐east monsoon and the second inter‐monsoon. A positive relationship is found between labour demand and rainfall in the first inter‐monsoon. Overall, predicted changes in rainfall by 2050 are anticipated to reduce labour demand by approximately 1,175,000 person‐days per year across Sri Lanka's tea plantation sector. This is likely to have considerable social and welfare implications, particularly for the Indian Tamil women who comprise the majority of the sector's workforce. 相似文献

The complexity of modern farm management places great demands on the skill, knowledge and capability of farm managers and their families. Keeping abreast of emerging technologies and innovations that can affect each key farm enterprise, and knowing how best to marshal the resources required for profitable farm production, are key tasks of farm management. This study draws on a longitudinal data set of 240 broadacre farmers to compare and analyse their farm performance over a decade. Using structural equation modelling, we examine relationships between the farm family's involvement in training, their human capital, their use of various innovations and ultimately the linkages of these factors to farm financial and productivity performance. Several statistically significant inter‐relationships are found, and some factors are shown to have significant positive links to farm performance. We find that training undertaken by the farm family, the farm family's human capital and their use of innovations, particularly key cropping innovations, have significant beneficial impacts on farm performance. The farmer's skills in time and organisational management, their engagement in business planning and the unique environmental characteristics of the farm also significantly and positively influence farm performance. 相似文献

企业会计报表中的显性负债大部分是由于企业潜在的隐性负债聚集而生成的,是企业内外各种因素长期积淀的结果。如何化企业隐性负债为显性收益,须从企业战略高度去思考。本文在叙述企业隐性负债形成的时代背景的基础上分析企业负债形成的动因,并寻求其解决的途径。 相似文献

This article develops a novel micro-approach for the empirical evaluation of Marx's law of the tendency of the rate of profit to fall. Contrary to the traditional method which uses national macroeconomic data, this approach utilises data taken directly from company reports and accounts. The principal advantage of this approach is that it provides an accurate measurement of the value composition of capital, devoid of the measurement limitations of the traditional method regarding variable capital which stem from the inability to distinguish productive from unproductive labour. A disadvantage, however, is that this approach does not cover the entire national economy. The application of the proposed micro-approach to the ongoing Greek crisis yields results which are congruent with the traditional method and reinforce other recent studies linking the current crisis with low profitability. 相似文献

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

We investigate the relationship between the degree of competition and the stability of collusive behaviour, by introducing the element of relative performance in the objective functions of the firms. We show that an increase in the degree of competition destabilizes the collusion. This relation differs starkly in the standard symmetric Cournot and Bertrand duopoly models, with the former being more unstable than the latter. 相似文献

Summary Expert systems are a product of the new technology. They provide the means for computerizing human expertise. This necessitates a more explicit understanding of the latter, provides an additional source of it and presents the possibility of enhancing the competence of that expertise. The paper argues that in the face of increased competition for investment funds the development industry needs to adopt a more sophisticated approach to project assessment. Two examples, with respect to planning law and retail investment appraisal, are developed to indicate the potential of the expert system approach. Ultimately expert systems challenge appeals to ‘feel’, ‘experience’ and judgement’ in human decision‐making; if successful, however, they promise improved profitability. 相似文献
