Co-production of service innovations through dynamic capability enhancement

The main aim of this paper is to investigate the effect of co-production practices with customers on service innovation. Specifically, we sought to determine whether dynamic capabilities (the specific abilities a company has to shape, reshape, configure, and reconfigure idiosyncratic assets to respond to changing technologies and markets) could mediate the effect of co-production on service innovation. In this paper, we examine the factors that could influence co-production practices and determine whether organizational commitment moderates the effect of co-production practice on an organization's dynamic capabilities. Using a survey approach of Taiwanese firms, we showed that dynamic capability fully mediates the effects of co-production practice on service innovation and that market orientation and customer matching have a significant influence on co-production practices. In addition, this study has empirically demonstrated that service firms would be well advised to engage in developing service innovation through enhancing their own dynamic capabilities.     

The optimal asset allocation of the main types of pension funds: a unified framework

The existing literature deals with the optimal investment strategy of defined benefit (DB) or defined contribution (DC) pension plans. This article’s objective is to compare the optimal policies of different types of pension plans. This is done by first defining an original framework, which is based on the distinction between the nature of the guarantee—which can be internal or external—offered by or to a pension fund. This framework allows to establish links between optimization programs of DC, DB and targeted money purchase schemes. The case of an internal guarantee appears as a standard portfolio insurer’s problem. The second kind of guarantee, not analyzed in the literature yet with regard to the resulting optimal policy, is characterized by the existence of an option in the final wealth definition. Four funds are present in the internal guarantee optimal allocation: the speculative component, the preference independent guarantee- and contribution-hedge terms and the preference dependent state variable-hedge fund. The external guarantee program, solved with an original method using the principles of standard options theory, yields an optimal policy incorporating the delta of the option embodied in the final wealth definition. The conclusion is that the resulting optimal portfolio policy becomes riskier.

Optimal excess-of-loss reinsurance contract with ambiguity aversion in the principal-agent model

ABSTRACT

We discuss an optimal excess-of-loss reinsurance contract in a continuous-time principal-agent framework where the surplus of the insurer (agent/he) is described by a classical Cramér-Lundberg (C-L) model. In addition to reinsurance, the insurer and the reinsurer (principal/she) are both allowed to invest their surpluses into a financial market containing one risk-free asset (e.g. a short-rate account) and one risky asset (e.g. a market index). In this paper, the insurer and the reinsurer are ambiguity averse and have specific modeling risk aversion preferences for the insurance claims (this relates to the jump term in the stochastic models) and the financial market's risk (this encompasses the models' diffusion term). The reinsurer designs a reinsurance contract that maximizes the exponential utility of her terminal wealth under a worst-case scenario which depends on the retention level of the insurer. By employing the dynamic programming approach, we derive the optimal robust reinsurance contract, and the value functions for the reinsurer and the insurer under this contract. In order to provide a more explicit reinsurance contract and to facilitate our quantitative analysis, we discuss the case when the claims follow an exponential distribution; it is then possible to show explicitly the impact of ambiguity aversion on the optimal reinsurance.     

不同碳排放达峰情景对产业结构的影响——基于动态CGE模型的分析

依据2017年投入产出表数据,运用可计算一般均衡理论,构建包括13个中间产业部门和5个能源产业部门的动态CGE模型,考量不同碳排放达峰情景对于产业结构的影响。结果显示：碳减排政策能促进产业结构优化,包括农业、轻工业和服务业等在内的低碳产业部门在总产出中占比增加,高耗能产业部门如非金属矿物加工业、金属加工业等在总产出中占比下降;对能源产出结构影响显著,高碳能源如煤炭、石油在能源产出比例下降,低碳能源如天然气在能源产出比例增加,其中可再生能源比例上升幅度最大。鉴此,应完善碳交易市场运行配套政策和环境,加大技术创新力度,促进产业结构和能源结构优化升级。     

工业园内企业年龄构建与环境污染相关性研究

针对目前工业园概念的惯性认识,从仿生学理论基础上提出工业园的建立需要加入年龄的考虑,并依据现代企业的经营周期与企业年龄的相关性,提出企业年龄决定企业环境容量需求,合理企业年龄构建是工业园动态生态化的前提,动态生态工业园是区域环境容量合理调配的基础。合理搭建工业园内企业年龄结构是控制环境污染的重要前提。     

非营利组织信息披露与社会捐赠:一个博弈分析

对非营利组织来说,提高自身持续发展能力为社会提供公益服务是其目标之所在。实现这一目标,非营利组织必须建立一个固定的社会捐赠群体来获取稳定的资金来源。通过一个完全信息动态博弈模型的分析可知,非营利组织在管理和运作中只有充分披露所接收的社会捐赠款的使用效率和效果,才能满足捐赠人的信息需求并使其享受到捐赠行为所带来的效用,进而采取进一步捐赠行动,非营利组织也由此提高其社会公信力,并能持续地获得资金来源。

经济周期波动与产业结构调整的动态关系研究——以山西省为例

基于山西省1952～2010年的数据,发现第一、第二产业波动是引起山西经济周期波动的格兰杰原因,基于脉冲响应、方差分解和状态空间模型的实证结果表明,山西第一产业波动对宏观经济波动的整体推动力逐年减弱,第二产业的影响一直都是最大的,而第三产业的影响稳中有升,这也很好地解释了山西经济实现高速增长的同时其经济波动幅度逐渐变小的现象。保持山西国民经济的又好又快发展必须促进三次产业的协调发展,特别是要加快第三产业的发展。

法律风险的有效控制对企业的发展至关重要。基于当前企业法律风险的复杂性,改变以往的企业法律风险研究的视角,从动态性控制的角度进行企业法律风险的有效防范和控制。在此基础上,将法律风险周期这样一个循环理念贯穿于法律风险防范机制的构建当中,并基于这个分析视角,提出了法律风险动态性控制的流程,为企业有效控制法律风险提供一个全新的方法。     

改进的动态反馈负载均衡算法

本文提出了一种改进的动态反馈负载均衡算法,在负载均衡过程中既考虑后台服务器的当前负载,又考虑后台服务器的处理能力,根据每台服务器当前负载比例值的大小合理分配用户请求,进而调整服务器间处理请求的比例,避免服务器超载时依然收到大量的请求,使平均应答时延和吞吐量等获得较好的性能,集群的整体性能得到提高。
