Willingness to Pay to Reduce Mortality Risks: Evidence from a Three-Country Contingent Valuation Study

Valuing a change in the risk of death is a key input into the calculation of the benefits of environmental policies that save lives. Typically such risks are monetized using the Value of a Statistical Life (VSL). Since the majority of the lives saved by environmental policies are those of older persons, there has been much recent debate about whether the VSL should be lower for the elderly to reflect their fewer remaining life years. We conducted a contingent valuation survey in the UK, Italy and France designed to answer this question. The survey was administered in these three countries following a standardized protocol. Our results suggest that the VSL is €1.022 million or €2.264 million, depending on whether we use median or mean WTP. The VSL is not significantly lower for older persons, but is higher for persons who have been admitted to a hospital or emergency room for cardiovascular and respiratory problems. Income is positively and significantly associated with WTP. The income elasticities of the WTP increase gradually with income levels and are between 0.15 and 0.5 for current income levels in EU countries. We use the responses to the WTP questions to estimate the value of an extension in remaining life expectancy. The value of a loss of one year’s life expectancy is €54,000 or €163,000.     

投资选择权约束、意见分歧与中国股市风险

特定的股票总是被市场上特定的投资者群体持有 ,以反映该投资者群体对投资资产价格的评估意见。投资者意见的分歧会导致股票市场的资产出清价格偏离均值 ,股票价格趋于均衡的波动幅度也会变大。中国股市上投资者投资选择权的约束加大了投资者的意见分歧。扩大投资者的投资选择权来促进投资者意见分歧程度的缩小能有效降低中国股市的风险。

OWNERSHIP STRUCTURE AND FIRM EXIT ROUTES

ABSTRACT

Our study presents empirical evidence about the role of ownership structure for firm exit probability by explicitly differentiating between distinct exit routes (bankruptcy and forced liquidation, voluntary liquidation, mergers and acquisitions – M&A, and removal from the court register). Based on the population of Slovenian firms in the 2006–2012 period and using multinomial probit, our findings support the predictions of agency theory. Ownership concentration, share of the largest owner, and the difference in shares between two largest owners all decrease the likelihood of exit for all studied exit routes but M&A. The magnitude of their impact is largest for exits, in which owners play a decisive role, i.e. voluntary liquidation and removal. The link between the number of primary owners and exit likelihood is U-shaped with the lowest exit probability for firms with around two owners.     

我国中西部县域实施PPP模式的风险探究

在问卷调查的基础上，构建我国中西部县域PPP模式的风险因素评价指标体系。经过风险指标权重的计算，从19个风险中筛选出9个制约中西部县域PPP项目的关键风险因素，并通过相关检验和因素分析将其划分到4个关键风险组群，分别为政治风险、经济风险、市场环境风险和合作风险。结果显示：政治风险为制约PPP发展的最主要风险组群，而项目收益不足则是评分最高的单项风险因素。

基于不确定运输时间的军械紧急调运模型研究

针对运输时间不确定的军械紧急调运问题，将运输时间处理为模糊随机变量，建立在任务时间限制期下的最大可能性路径选择模型以确定调运路径。而后，引入超期风险概念，建立以超期风险最小为首要优化目标的军械紧急调运多层觇划模型，实现了对调运方案的优选。最后，给出一个具体军械调运实例来验证模型的适用性。
