技术成果熟化创业:机制设计与模式选择

技术成果熟化的机制设计需要满足信息有效、降低交易成本和激励兼容等条件。"一条龙"模式、"模块化"分工模式、"孵化器"模式、"专利集合"模式等是为促进术成果顺利熟化和技术新创企业成长的4种可行模式,其共性在于减少交易环节,打通和理顺技术价值链与产品链、融资链和管理链,使成果在相对一体化机制中得以熟化育成增值。技术成果熟化模式选择取决于熟化交易各方对预期与实际交易价值、成本和风险的比较。     

物联网产业联盟风险评估——基于变权理论与可拓理论的结合

将变权理论与可拓理论相结合,构建了用于评估物联网产业联盟风险的变权可拓模型。用物元概念和可拓集合来判断联盟风险属于某等级风险的程度,利用距函数定义关联度,从而使识别定量化和精确化;运用变权理论,根据不同条件取适当的指标权重以反映其本质属性,克服了传统常权赋值的局限。最后,以无锡"感知中国"物联网联盟为例,运用提出的风险评价方法对其风险进行评估。结果表明,该方法具有科学性和有效性。     

基于状态空间模型的汇率和货币供给对通货膨胀影响的实证分析——基于央行资产负债表的视角

从分析人民银行资产负债表的变化出发,运用状态空间模型实证分析了2005年7月至2012年6月中国汇率和货币供给对通货膨胀影响的动态时变过程。研究结果表明:人民币汇率升值对通货膨胀有一定的抑制作用,但其效果较弱;货币供给对通货膨胀有较大的正向推动作用,货币供给的持续增加是人民银行资产负债表中资产方的外汇占款科目不断增加导致负债方的基础货币持续增加的结果。     

中蒙俄文化廊道——"丝绸之路经济带"视域下的"万里茶道"

丝绸之路自开辟以后半通半停,奥斯曼帝国兴起后彻底中断;欧洲商人的"地理大发现"从南、西、北三个方向到达东方的同时,山西商人开辟"万里茶道"到达西方,说明晋商"万里茶道"与开创精神的重要世界地位. 通过"万里茶道"联合申遗,建设中蒙俄文化廊道,依托国际大通道,开展经贸文化旅游交流,展开"丝绸之路经济带"的"文化翼",对于建设"丝绸之路经济带"具有不可或缺的重大作用,在山西未来发展史上具有重要的战略意义.     

中国农业保险的赔付风险:风险测度与应对策略——基于1984~2012年农业保险与财产保险赔付率的滤波分解与比较

由于农业保险所承保的农业自然灾害具有统计学上的不可预测性,灾害学上的时空延展性和经济学上的不可控性,使得经营农业保险的保险公司面临较高赔付风险. 为测算我国农业保险的赔付风险度,收集整理1984~2012年农业保险与财产保险赔付率数据,采用H-P滤波分解法对其进行长期趋势与短期波动的分解和比较分析. 研究发现:我国农业保险整体赔付水平和赔付的波动幅度远高于财产保险,验证了农业保险具有高风险经营的特性. 但是近年来,农业保险长期赔付趋势呈现平稳略微下降态势,短期波动幅度逐步收敛. 未来随着经营主体的增加,农业保险经营中须把握保险保障度的提升与保险公司经营风险管控的有效平衡;农业保险的适当盈利性与福利改进的有效融合.     

A Tale of Two Anomalies: Higher Returns of Low‐Risk Stocks and Return Seasonality

Prior studies have shown that low beta and low volatility stocks earn higher average returns than high beta and high volatility stocks, contradicting the prediction of the capital asset pricing model and the fundamental relationship between risk and return. In this paper, we demonstrate that this phenomenon is driven by the seasonality of stock returns. We show that the risk‐return tradeoff does hold in the nonsummer months, and that switching to a portfolio of low‐risk stocks in summer outperforms—both in terms of absolute and in risk‐adjusted returns—buy and hold strategies as well as the Sell in May strategy of switching to treasury bills in summer.     

Fundamentals and Exchange Rate Prediction Revisited

This paper measures latent fundamental exchange rates with independent component‐based rates constructed from a cross‐section of exchange rates and then uses their deviations from exchange rates to forecast. Empirical results indicate that the independent component‐based model and its Taylor rule and purchasing power parity augmented models are superior to the random walk in predicting exchange rates. These results are robust to several scenarios and are likely to be observed if the U.S. sources and the recursive scheme are applied. Our results reveal that information regarding the third moment of exchange rate changes is helpful to explain exchange rate movements.     

Interest Rates and Credit Risk

This paper explores the effects of shifts in interest rates on corporate leverage and default in the context of a dynamic model in which the link between leverage and default risk comes from the lower incentives of overindebted entrepreneurs to guarantee firm survival. The need to finance new investment pushes firms' leverage ratio above some state‐contingent target toward which firms gradually adjust through earnings retention. The response to interest rate rises and cuts is both asymmetric and heterogeneously distributed across firms. Our results help rationalize some of the evidence regarding the risk‐taking channel of monetary policy.     

Are analysts' cash flow forecasts useful?

This study provides evidence that the cost of equity capital decreases with the number of analysts who issue both cash flow and earnings forecasts (cash analysts). The evidence also shows that cash analysts reduce information asymmetry and predict long‐term earnings more accurately than analysts who issue only earnings forecasts. Taken together, these findings suggest that cash analysts provide market participants with high‐quality information and, as a result, firms benefit from cash analyst coverage in the form of a reduced cost of equity capital.     

财务公司产业链金融信用风险控制机制研究--基于缓解中小企业融资约束的视角

从缓解中小企业融资约束的视角出发,对基于抵质押制度和声誉机制共同激励的财务公司产业链金融信用风险控制机制进行研究。在一个中小企业类型为单边非完全信息结构的假设条件下,建立博弈模型分析抵质押制度与声誉机制共同激励下中小企业的行为选择,研究发现共同激励可以有效扩大财务公司的安全授信边界,既能确保财务公司控制中小企业信用风险,又能增加中小企业的授信额度。
