基于双渠道环境下在位制造商的阻止策略研究
双渠道定价 链外进入 阻止策略
2018/11/15
双渠道运营以提高顾客的购买体验为核心，不仅要求各渠道建立合理定价策略，同时要实现渠道间协同，这放大了制造商与零售商之间乃至整条供应链的冲突，进一步刺激链外企业进入行为，从而加剧在位制造商采取阻止策略.基于链外进入行为的普遍性与在位阻止的现实性，研究结果表明：当进入成本较低时，在位制造商无法阻止外来制造商进入；当进入成本过高时，在位制造商不用改变定价即可阻止进入；而当进入成本适中时，在位制造商可以通...
内生性回收率与信用风险度量研究
因子扩散过程 信用风险度量 数值模拟 实证检验
2016/2/29
在信用风险模型中,外生性回收率的设定会忽略回收率对损失分布尾部的影响,而且会导致潜在的模型风险。本文将因子扩散过程引入结构信用风险模型,获得了回收率和违约概率之间的内在关系,利用Monte Carlo模拟方法数值分析了预期回收率对违约概率和资产价值波动率的依赖性,结果表明预期回收率与违约率之间具有很强的负相关关系,而且这种相关关系会受到债务人资产价值波动率的正向影响。在内生性回收率下,推导了信用损...
