Summary. We show, in the Choquet expected utility model, that preference for diversification, that is, convex preferences, is equivalent to a concave utility index and a convex capacity. We then introduce a weaker notion of diversification, namely “sure diversification.” We show that this implies that the core of the capacity is non-empty. The converse holds under concavity of the utility index, which is itself equivalent to the notion of comonotone diversification, that we introduce. In an Anscombe-Aumann setting, preference for diversification is equivalent to convexity of the capacity and preference for sure diversification is equivalent to non-empty core. In the expected utility model, all these notions of diversification are equivalent and are represented by the concavity of the utility index.

Summary. We discuss a competitive (labor) market where firms face capacity constraints and individuals differ according to their productivity. Firms offer two-dimensional contracts like wage and task level. Then workers choose firms and contracts. Workers might be rationed if the number of applicants exceeds the capacity of the firm. We show that under reasonable assumptions on the distribution of capacity an equilibrium in pure strategies (by the firms) exists. This result stands in contrast to the case of unlimited capacity. The utility level is uniquely determined in equilibrium. No rationing occurs in equilibrium, but it does off the equilibrium path.

解释方法论在日本民诉法研究中并不是显著的命题。长期以来,日本民诉法解释并不特别重视法律条文和立法者本意,解释方法论遵循的主要是利益衡量论,近年始有学者对它提出批判。日本民诉法解释方法论选择既源于民事诉讼法的目的被定位于纠纷解决,也与战后比较法研究中利益衡量论的引入有关。日本民诉法利益衡量论有别于民法中的利益衡量论,也有别于受德国法影响的亲实体法解释方法论,这种方法论并不局限于衡量或分配原被告之间的财产或价值,更多地蕴含了对作为制度利用者的当事人的便利、 制度运营者的公共利益、民事诉讼程序的动态发展等要素的考量。  相似文献

Capacity reduction has been a recurrent theme in China's economic policy. The central government takes various administrative measures to remove excess capacity, accumulated mainly due to underpriced production factors and distorted incentives. I evaluate the de-capacity policy in a series of models and prove that its effects depend critically on its persistence and monetary policy regime. Under an interest rate peg, a transient policy that changes markup temporarily is ineffective and even expansionary, whereas a persistent policy is effective due to a negative wealth effect. A permanent de-capacity policy can lead to over-reactions in macro variables because the interest rate peg adds positive feedback to the economy. Therefore, the de-capacity policy has greater uncertainty under the interest rate peg. As a policy tool, it easily deviates from its target and brings about excessive volatility. However, long-run price stability and a gradually advanced de-capacity policy are conducive to the achievement of policy targets.  相似文献

基于新技术与新知识的高技术服务业跨界融合是传统企业实现创新资源优化配置、创新研发和商业转化的重要因素。因此,运用熵指数测度全国各省区高技术服务业与资源型产业融合水平,并利用2014—2017年资源型上市公司面板数据检验两大产业融合对资源型企业两阶段创新效率的影响,同时探讨企业吸收能力的调节作用。结果表明:现阶段高技术服务业和资源型产业融合程度不高,但发展态势良好,处于从失调走向协调的转变期;产业融合对资源型企业创新研发效率短期无显著影响,长期存在抑制作用,资源型企业技术能力刚性导致对新技术的排斥,且较大的产业间认知差距削弱了产业间良性互动带来的技术扩散效应;产业融合对创新转化效率呈先抑制、后促进效应,就长期而言,产业融合具有良好的创新转化推动力;资源型企业吸收能力分别在产业融合与滞后一期创新研发效率及滞后三期创新转化效率的关系中起正向、负向调节作用,表明资源型企业吸收能力构建尚不全面。  相似文献

This study introduces an optimal capacity and operation design of a robot logistics system that can reduce human workload in the hotel industry. In hotels, there are several duties that can be replaced by robots such as accompanying guests to the certain areas, delivering specific items to the guest rooms, and transporting some items that guests want to be removed from the guest rooms. To apply the robot logistics system in the hotel industry, the capacity and operation design should be prepared adequately. For that, a mathematical model-based optimization technique is used to decide the number of robots with the concept of minimizing total investment cost and to derive the optimal job assigning with the purpose of maximizing total covered jobs. In addition, a numerical example is performed to validate the proposed mathematical model and the sensitivity tests are examined to reflect the random features.  相似文献

基于利益相关者理论,通过文献研究与实地调研,梳理了影响国家级新区绿色增长能力建设的主要因素,并应用Grey DEMATEL方法进行影响因素因果关系分析,在此基础上进一步剖析国家级新区绿色增长能力建设内在机理。研究结果表明:法律法规完善性是影响国家级新区绿色增长能力建设的根本性动力因素,同时,也是新区绿色增长能力建设内在机理的重要外在驱动力。此外,当地居民环境意识也是影响国家级新区绿色增长能力建设的重要结果性因素,而企业绿色管理实践、绿色技术进步与创新能力作为重要的关键性因素,对国家级新区绿色增长能力作用显著,是国家级新区绿色增长能力建设的重要内在驱动力。  相似文献

This paper first sets up a firm heterogeneity trade model and shows that given capital stock and productivity, export firms will have higher rates of capacity utilization. In addition, given capital stock and fixed export costs, firms with higher productivity are more likely to export. I then use the 2012 Chinese enterprise survey from the World Bank to empirically investigate the impact of participation in export on Chinese firms’ capacity utilization rate. The results show that on average, export firms have capacity utilization rate 1.55–2.01 percent higher than non-export firms, which amounts to 14.6–18.9 percent of the standard deviation of capacity utilization rate in the sample. I also find that firms with a larger part of shares owned by the government have lower capacity utilization. Stronger market competition leads to over-investment and therefore lower capacity utilization rate. Faced with more rigorous labor market regulation, firms will substitute capital for the use of labor, resulting in higher capacity utilization rate.  相似文献

This paper examines a three-faceted approach for runway capacity management, based on the runway configuration, a chosen scheduling approach, and an aircraft separation standard. These factors prompt alternative runway settings that are encapsulated using a classical mixed-integer formulation. The optimal solution for each runway setting is compared against our proposed optimization-based heuristic. This integrated approach is applied to investigating the transition from the (Old) Doha International Airport to the New Doha International Airport. Our empirical study based on historical data reveals that the proposed heuristic consistently yields optimal or near-optimal schedules, with considerable savings in fuel cost and reductions in delays, while preserving the spirit of an FCFS sequencing policy.  相似文献
