IPO发行制度与信息披露质量——基于保荐制实施与否的比较
拟上市公司 保荐制 信息披露质量
2015/6/25
本文针对近年来国内IPO公司信息披露质量不尽人意的现状,综合考虑拟上市公司、保荐人和监管部门之间的委托代理关系,采用信息不对称问题的研究框架比较了有无保荐制的发行制度下的社会效益最优模型。理论上,通过求解各模型的均衡解并对结果进行比较发现,在适宜的监管函数下保荐制能够一定程度上提高拟上市公司的信息披露质量。然而通过实证分析发现,目前国内IPO保荐制在提高信息披露质量方面表现堪忧,主要原因在于监管行...
基于广义模糊软集理论的云计算资源需求组合预测研究
相似性度量 组合预测 自适应神经模糊推理系统
2015/6/25
论述了云计算资源需求预测的作用,提出了新的基于夹角余弦的广义模糊软集相似性度量方法,将相似性度量结果与预测精度相结合来获得各单项预测模型的权重,并针对云计算环境中资源需求所表现出的短期动态性和长期周期性特征,选用自适应神经模糊推理系统ANFIS和季节性ARIMA模型SARIMA作为单项预测模型,以此构建基于广义模糊软集理论的组合预测模型GFSS-ANFIS/SARIMA。最后将该模型用于云计算环境...
无统计信息假设下的多阶段报童决策
无统计假设 弱集成算法 收益损失函数
2015/6/25
在不对需求做任何统计假设的情形下,该文用理论计算科学兴起的集成专家意见的弱集成算法研究多阶段报童决策。弱集成算法是一种指数加权平均集成方法,在一定的初始权重下,根据损失函数在线调整专家意见的权重。基于收益损失函数和固定订购量的专家意见,得到了与从累积收益角度研究相一致的决策方法;并扩展研究了带有回收价值的情形。理论上证明了决策方法的累积收益损失几乎不超过最优专家意见的累积收益损失。通过数值算例验证...
