我国职业年金制的整合构建问题探析

随着中国经济市场化改革的进一步深化,作为养老保障的第二支柱,中国的职业年金制度终将被整合构建起来。本文从职业年金概念的辨析开始,采用文献研究法梳理出职业年金制整合设计的几个基本问题。并有针对性地提出将职业年金制设计为：企业、机关事业单位等作为雇主参与职业年金筹资;筹资模式采用基金制的缴费确定型计划;缴费率目标值设定为由雇主和雇员共同承担10％~15％,且替代率目标值设定为40％~50％;职业年金基金实行市场化运作。     

新时期行政管理体制改革问题分析

行政管理体制作为上层建筑,其创建、调整及改革的动力在不同时期有着不同的表现。当前地方政府对区域经济一体化潜在经济社会利益的诉求是推动行政管理体制改革的重要动力,但对具体实施路径的分析却存在较大差异。在梳理既有文献的基础上,提出区域协调发展的策略和路径,并指出其中的关键问题。在上述分析框架的基础上,提出梳理既有法律法规体系、构建区域共同市场规则等对策性建议。     

“He's Doing Fine”: Hope Work and Emotional Threat Management Among Families of Seriously Ill Children

In this study, I examine how people in emotionally fraught circumstances strategically structure social interactions in order to protect fragile emotional states. Data come from interviews and observations with 18 families of children being treated for life‐threatening conditions at an elite university research hospital. I show how families worked to ward off emotional threats to their ability to maintain hope that their children would recover by preempting and restructuring social interactions with friends and family members and pruning social networks. These efforts allowed families to minimize reciprocal obligations and avoid encountering pessimistic reflected appraisals that might trigger “emotional shortcuts” leading to states of fear and anxiety. Similar efforts to reconstruct social interactions and social networks may be common among those working to maintain fragile emotional states in a variety of challenging circumstances.     

基金发行潮与管理公司绩效

区别于传统以基金作为独立个体的研究,本文以基金的母体——基金家族作为研究对象,重点考察以下问题:为何基金家族纷纷发行新基金?基金家族的迅速繁衍是否损害了其投资绩效?文章从理论上探讨了基金家族热衷于发行新基金的原因。并运用随机前沿分析(SFA)方法,以测算基金家族投资绩效为切入点,重点检验了新基金发行对家族业绩的影响。发现基金家族总体业绩偏低,新基金发行在短期能提高家族业绩,在长期会损害家族业绩。为此,文章进一步探讨了新基金发行对家族业绩的门槛效应。发现要有效促进基金家族业绩,单个基金家族半年内新发行基金数不能超过3只,其旗下基金总数不能超过11只。根据研究成果,文章提出了相关政策建议。     

供应突发事件下基于CVaR的供应链订货决策及协调

供应突发事件下,引入条件风险值(conditional value at risk-CVa R)刻画了零售商的运营目标,构建了收益共享契约下的供应链订货模型,着重研究了CVa R下的供应链协调及零售商最优订货量对供应商可靠性及对其自身的风险规避系数的敏感性。研究表明:收益共享契约具有一定的鲁棒性,能协调突发事件风险下的供应链;风险规避型零售商的最优订货量总是不小于风险中性情况,且风险规避程度越高,订货量越大;最优订货量对供应商可靠性均值的敏感性不依赖于零售商的风险规避程度,且均值越小,最优订货量越大,这与风险中性情况是类似的;最优订货量对供应商可靠性标准差的敏感性则依赖于零售商的风险规避程度,当零售商的风险规避程度较高时,供应可靠性标准差越大,最优订货量越大,这与风险中性情况是相反的。     

Work Design and Integration Glitches in Globally Distributed Technology Projects

In a technology project, project integration represents the pooling together of complete, interdependent task modules to form a physical product or software delivering a desired functionality. This study develops and tests a conceptual framework that examines the interrelationships between the elements of work design, project integration challenges, and project performance. We identify two distinct elements of work design in technology projects: (i) the type of project organization based on whether a technology project spans a firm boundary (Domestic‐Outsourcing) or a country boundary (Offshore‐Insourcing) or both boundaries (Offshore‐Outsourcing) or no boundaries (Domestic‐Insourcing), and (ii) the joint coordination practices among key stakeholders in a technology project—namely, Onsite Ratio and Joint‐Task Ownership. Next, we measure the effectiveness of project integration using integration glitches that capture the incompatibility among interdependent task modules during project integration. Based on analysis of data from 830 technology projects, the results highlight the differential effects of distributed project organizations on integration glitches. Specifically, we find that project organizations that span both firm and country boundaries (Offshore‐Outsourcing) experience significantly higher levels of integration glitches compared to domestic project organizations (Domestic‐Outsourcing and Domestic‐Insourcing). The results further indicate that the relationship between project organization type and integration glitches is moderated by the extent of joint coordination practices in a project. That is, managers can actively lower integration glitches by increasing the levels of onsite ratio and by promoting higher levels of joint‐task ownership, particularly in project organization types that span both firm and country boundaries (Offshore‐Outsourcing). Finally, the results demonstrate the practical significance of studying integration glitches by highlighting its significant negative effect on project performance.     

Quality Management in Multi‐Level Supply Chains with Outsourced Manufacturing

Outsourcing stretches supply chains longer with added contract manufacturers responsible for the manufacturing of parts and final products. Should a firm change its quality management approach as its supply chain becomes longer with outsourced manufacturing? This paper studies a brand owner's optimal choice between two commonly used quality management approaches: an inspection‐based approach and an external failure‐based approach, in two supply chains – a dyadic supply chain and a multi‐level supply chain where the brand owner outsources manufacturing to an independent contract manufacturer. Our study finds that the brand owner's optimal choice between the two quality management approaches could be opposite in the two supply chains. Specifically, we show that if agency costs exist between the contract manufacturer and the brand owner, the brand owner may prefer an inspection‐based approach in the multi‐level supply chain in contrast to preferring an external failure‐based approach in the dyadic supply chain. In particular, inspections can be effective for the brand owner to limit the manufacturer's profit by excluding defective finished products and components, which in turn reduce agency costs in the multi‐level supply chain. Hence, the efficiency of an inspection‐based approach relative to an external failure‐based approach can be higher in the multi‐level supply chain as compared to the dyadic one. Our findings suggest that firms should adjust to changes in supply chain structures and re‐evaluate the efficiencies of different quality management approaches accordingly.     

Managing Demand Uncertainty through Core Acquisition in Remanufacturing

We discuss the optimal raw material acquisition strategy for a third party remanufacturer (3PR). We specifically investigate whether a 3PR should acquire used products or cores in bulk with uncertain quality levels, or in sorted grades with known quality levels; and whether to acquire and remanufacture cores before the demand is realized (planned acquisition), or after the demand is realized (reactive acquisition), or on both occasions (sequential acquisition). When only sorted cores are acquired, we find that, (i) it is optimal to acquire cores in multiple grades to balance acquisition and remanufacturing costs; (ii) if reactive acquisition is possible, it reduces the assortment size (number of grades in which cores are acquired) and the total inventory acquired in the planned acquisition; and (iii) the optimal portfolio of grades to acquire and the optimal acquisition and remanufacturing quantities of these grades can be determined analytically. When bulk cores are acquired in addition to sorted cores, the property of reduction in assortment size of the planned acquisition is preserved. We also show that the 3PR should acquire only a fraction of the demand in planned acquisition, and leave the rest for reactive acquisition. This fraction changes during the lifecycle of a remanufactured product. Using a combination of empirical and realistic data from a smartphone remanufacturer we show that sequential acquisition increases expected profit by up to 8% and 27% over only planned and only reactive acquisitions respectively, and reduces the inventory acquired by up to 21% over only planned acquisition.     

Investment in Shared Suppliers: Effect of Learning,Spillover, and Competition

We investigate the optimal strategies for firms to invest in their suppliers when the benefits of such investments can spillover to other firms who also source from the same suppliers. We consider two Bayesian firms that can invest in improving the quality of their shared supplier; the firms do not have complete information on the true quality of the supplier, but they update their beliefs based on the supplier's performance. We formulate the problem as an investment game and obtain Markov perfect equilibria characterized by the investment thresholds of both firms. The equilibrium investment strategies of the two firms are characterized by a region of preemption and a region of war of attrition. We also examine how the interplay between spillover, competition, and returns from the investment at shared suppliers affect the investment threshold and the time to the leader's investment, and identify the conditions under which competition delays or hastens the first investment in a shared supplier.
