We build a game theoretical model to examine how the level of information advantage of insiders and the competition between insiders and sophisticated investors affect stock price movements and traders’ trading strategies and profits. We show that the competition between insiders and sophisticated investors can reduce the losses of less sophisticated investors, and thus alleviates the disadvantaged position of the less sophisticated investors. Further, traders’ profits are affected by the accuracy of insiders’ private information, and the number of days that insiders have obtained the information in advance. These findings show the importance of information transparency and the role of sophisticated investors in limiting insiders’ trading advantages and mitigating the expropriation of investors by insiders. 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

The Greek economic crisis is primarily structural and the result of an international economic impasse that developed in 2007, with devastating implications for the struggling peripheral economies of Europe. This article suggests that falling profitability led to the stagnation of profits, which in turn discouraged new investment, decreased production and increased unemployment. The resulting recessionary economic environment, in conjunction with the mounting public debt and the austerity policies imposed on the Greek economy by the so-called ‘troika’ of creditors in 2010, has decimated the Greek economy even further, causing one of the worst economic crises since the Second World War. The article also provides some broad guidelines for an alternative economic policy. 相似文献

中国棉花种植成本收益的演变 总被引:1,自引:0,他引:1
棉花是国家重要战略储备物资,历年棉花的播种面积、产量及价格,对棉花市场造成巨大影响,也影响着棉花产业的健康发展。研究棉花种植成本的变动,直接关系到棉农的经济收益。为对我国棉花种植收益的演变进行探析,文章基于1990~2013年中国棉花种植成本收益数据,运用趋势分析与比较分析法,对我国棉花种植成本收益的变化趋势进行研究。研究发现:(1)我国棉花种植成本由1990年265.63元/667m~2,增加到2013年2 177.5元/667m~2,增加了1 911.87元/667m~2,增长了7.2倍,年均增长率9.58%;(2)成本利润率由1990年的最大值102.87%,下降到2013年-9.87%的最低值,未来提高棉花成本利润率压力较大;(3)棉花出售价格变量与棉花种植的长期平均成本变量对棉花成本利润率影响显著,未来我国棉花种植是否能够获利,价格将成为关键影响因素。研究结论:(1)我国棉花种植成本收益正处于"高投入,低产出",规模报酬递减阶段;(2)棉花出售价格变量与棉花种植的长期平均成本变量,是影响我国棉花成本利润率关键变量,且棉花出售价格变量的影响更显著。研究建议:(1)完善我国棉花价格市场形成机制,避免棉花市场价格出现剧烈波动;(2)通过优化棉花生产环节,降低棉花生产成本;(3)贯彻落实国家生产补贴政策,使补贴资金及时、足额发放到户。 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

文中主要论述了第三方仓储物流企业三大类共四种不同类型的盈利模式,包括空间仓储服务模式、增值服务模式和基于供需管理平台的服务模式,其中基于供需管理平台的服务模式可分为作为初级阶段管理增值模式和高级阶段的供需网控模式。文中最后还提出了模式转换的建议措施。认为,前两种模式是过去和当前第三方仓储物流企业的主要盈利模式,后两种模式则代表着企业未来的发展方向。 相似文献
