This analysis utilises a model of production under risk estimatedon Finnish farm-level data to measure farmers' risk attitudesin a changing policy environment. We find evidence of heterogeneousrisk preferences among farmers, as well as notable changes overtime in farmers' degree of risk aversion. This result is dueto the increase in the non-random part of farm income generatedby the policy change after Finland's European Union accession.The analysis confirms the assertion that agricultural policiesthat are decoupled from production do affect input use and cropmix through their effect on farmers' risk attitudes.  相似文献

Under the past Common Agricultural Policy (CAP) olive oil subsidy regime, farmers were eligible for subsidies on the basis of amount of olive oil produced. This led to an intensification of production and negative environmental effects on sloping land, such as loss of biodiversity and more soil erosion. In 2004 the olive and olive oil regime changed, with integration of support to olive farmers in the Single Payment Scheme (SPS). From 2006 to 2013 farmers receive a constant amount of subsidies, based on the average amount they received in the 4-year reference period 1999–2002.  相似文献

A mathematical programming model, calibrated on individual farmdata, is used to analyse the reform of the common market organisation(CMO) in the sugar sector of the European Union. The model includesa precautionary farm supply function for out-of-quota sugarbeet that is estimated as part of a simultaneous system of first-orderconditions. Simulation results from a sample of Belgian sugarbeet farms show that the sugar CMO reform induces differentsupply and income effects across farms depending on their shareof out-of-quota sugar beet relative to their total beet supplyand their quota rent. A further cut in the minimum price ofsugar beet initiates structural change in the farm sector.  相似文献

通过1997--2009年的贸易数据对中德两国的木质家具出口贸易进行了比较研究。利用CMS模型测算了拉动两国木质家具出口增长的原因,进而通过显性比较优势指数和贸易结合度指数的测算,实证分析了中德两国各自具有比较优势的产品类型以及双边木质家具贸易的结合程度。结果发现,竞争力效应和一般增长效应分别是拉动中国和德国木质家具出口增长的主要因素,两国分别在不同种类的产品上具有比较优势且两国问的木质家具贸易结合程度不高,具有巨大的合作发展潜力。  相似文献

This paper introduces a modeling method which simulates a village's response to population and market pressure. The method combines a recursive and dynamic linear programming model with a biophysical model of soil condition and plant growth that predicts yields and land degradation for different type of land, land use and cropping patterns. The linear programming model simulates farmers' plans aggregated at the village level under constraints of risk aversion, food consumption, land area, soil fertility, soil depth, labor and cash availability. Detailed agroecological factors determine Ihe main processes of land degradation. A large number of technological alternatives, representing different degrees of labor and/or land-saving techniques available in the study areas, are introduced, taking into account their respective constraints, costs and advantages. The method has been calibrated for a village located in the sub-humid region of Burkina Faso. Several simulations are carried out to the Year 2030. The results show that population pressure leads to intensification and investment in land conservation practices out not necessarily to better farm incomes. Increasing market opportunities can play a more positive role in boosting productivity, but for the next decades the best way to increase production per farmer is to let farmers migrate from the high-population-density areas to the low-population-density areas because, under the current economic conditions of most Sahelian countries, intensification per hectare is stil more expensive than the fallow system.  相似文献

论文以环渤海经济圈为例,采用DEA-Malmquist模型对环境资源约束下环渤海经济增长绩效进行研究,并进一步利用面板回归模型,对该地区全要素生产率的影响因素进行了实证分析。环境资源约束下,环渤海经济圈总体以及圈内各省市的全要素生产率都大于1,表明经济发展方式都都有一定程度的转变。不同的经济基础、地区工业结构以及对外开放程度会影响地区经济发展速度,同时能源利用和环境污染治理对经济增长绩效有显著负向影响。  相似文献

This paper examines the geography of two policy instruments – the Rural Enterprise Scheme (RES) and the Processing and Marketing Grant (PMG) – that formed part of the second ‘pillar’ of the Common Agricultural Policy (CAP) in England between 2000 and 2006. It starts by outlining the ongoing debate over the role of geography in policy research, an outcome of which has been a call for more empirical work that explores the ‘difference that place makes’ in the implementation of public funding mechanisms. The paper argues that the CAP is ripe for geographical analysis, as the Agenda 2000 reforms can be interpreted as moving it away from a ‘sectoral’ (agricultural) approach to a more ‘territorial’ (rural development) one. After outlining the place of the RES and PMG in the reformed CAP in England, the paper discusses three factors – farm size, proportion of land rented and location – that may have influenced their geographies. The distribution of grant approvals under these schemes is then mapped using location quotients. Following this, the potential influence of the factors outlined above is tested using the Kolmogorov–Smirnov statistic. The conclusion revisits the opening discussion by reflecting on the difference that place has made to the implementation of the PMG and RES.  相似文献
