我国金融机构的组织规模、空间分布与效率改进

金融机构的组织规模和网点分布密切相关,规模扩张通常意味着分支机构网点的空间扩张.金融业是关系密集型行业,关系在不同的金融产品和服务中的重要性是不一样的,其经营的经济规模也是不一样的.个人保险类金融产品关系性最低,其经营也最接近普通消费品的营销原则;公司类产品最具有关系性,其经营最依赖于银企双方的关系.金融产品和服务中关系型的经济规模较小,非关系型的经济规模较大.金融机构经营领域是不同关系类型的金融产品和服务的业务集合,这很容易使金融机构过度膨胀.通过机构专业化、组织集团化和配送一体化可以改变这一特征并提高金融机构运营效率.     

Monetary integration vs. real disintegration: single currency and productivity divergence in the euro area #

Productivity slowdown plays a prominent role in the build-up of the euro area crisis. This phenomenon affected member countries asymmetrically, causing divergence in their productivity trends. Recent research traces this divergence back to monetary integration. After reviewing the arguments that link real “disintegration” of the euro area to its monetary integration, we assess them empirically by modelling the evolution of labour productivity using a panel of sectorial data. The results indicate that monetary unification may actually have fostered divergence in productivity trends, and suggest some economic policy measures that could prevent further divergence.     

Distinguishing external from internal scale effects: The case of public infrastructure

The recent applied production theory literature focusing on the economic performance of firms has increasingly recognized the importance of scale effects on costs and therefore efficiency. These scale effects may include short run returns due to fixity of privately demanded inputs (i.e., capital, long run internal returns to scale, and external factors affecting costs. Since these different types of scale effects can be thought of as shifts in and movements along cost curves, the different cost effects of such factors can be identified in a framework which explicitly takes them into account in the definition ofscale.In this article we formalize such a framework, and then use it to measure short run, long run (internal) and external scale effects from fixity of private capital, nonconstant returns to scale and public infrastructure. We then use these measures to identify the impacts of these different scale factors on productivity growth. The focus on public infrastructure as an important external scale factor is motivated by the current theoretical and policy interest in this issue; we show how a structural production theory model provides a rich basis for the analysis of the cost effects of infrastructure investment.     

On a generalization of a class of production functions

In Appl. Econ. Lett. 18 (2011), 1777–1784, as a natural generalization of some famous production models with two inputs, C.A. Ioan and G. Ioan introduced a new class of production functions with constant return to scale, called sum production function, and proved three theorems of characterization for such production models. In this article, we give new and more simple proofs of these theorems, extending also the results to the case of increased/decreased return to scale. The generalization to the case of an arbitrary number of inputs is also discussed.     

当前我国公债政策方向选择

金融危机已经对中国经济以及全球经济的发展造成了极大负面影响。扩内需、保增长已成为当前我国经济的主导方针。作为宏观调控重要手段的公债政策,对促进经济增长有着非常重要的理论和实践意义。本文分析了公债政策对我国经济的影响,提出了对公债政策、公债规模选择和投资方向选择等方面的一些建议。     

实现经济平衡增长的公共支出规模分析

随着政府对经济干预程度的加强,公共支出对经济增长的影响日益提高,成为继劳动、资本、技术之后影响经济增长的又一重要因素。在一定时期、一定条件下,为实现一国经济平衡增长,应合理确定公共支出规模,明确界定公共支出范围,大力压缩公共消费支出,进一步加大预算外资金的管理力度,逐步将预算外资金纳入预算内管理,实现预算的综合与完整。     

企业慈善行为测量及其对员工职场精神力的影响

针对现有企业慈善行为测量单一化、短期化与外部化的局限以及从内部员工视角研究慈善战略价值的欠缺,开展了两个关联研究。在研究一中,采用归纳法开发并检验了一份包含内外部慈善的日常性企业慈善行为量表。结果显示,企业慈善行为具有一阶双因素结构,由外部慈善行为与内部慈善行为因素构成。该量表信效度较好,可用于实证研究。在研究二中,检验了企业慈善行为对员工职场精神力的影响,结果显示内外部慈善均对员工职场精神力有积极作用,其中内部慈善行为作用更强。员工的"与组织价值观一致"相对"团体感"和"工作意义"被企业慈善行为解释的程度最高,表明企业慈善行为受到了员工高度的价值认同。     

The productivity of private and social farms: Multilateral Malmquist indices for Slovene dairying enterprises

Applying programming techniques to farm-level panel data for four cooperative and 12 private dairy farms in the Yugoslav Republic of Slovenia gives estimates of technical efficiency, scale efficiency, and technical progress. These are used to construct multilateral Malmquist indices of total factor productivity (TFP). For the cooperatives, TFP growth has been slow and is attributable to technical progress. For the private farms, technical progress was also slow, but TFP growth was faster due to improved efficiency. Scale inefficiency explains the poorer absolute performance of the private farms, indicating the need for land reform as well as technological change.     

国债发行规模与GDP和财政支出的关系

国债作为政府筹集资金、缓解财政压力和实施宏观经济调控与现代金融管理的重要工具,适当的国债政策是实现财政政策和货币政策调控目标、促进经济增长的重要手段与保证。我国国债的发行对支持经济的发展起到了重要的促进作用。要优化国债结构,实现国债结构进一步的合理化,就需逐步扩大地方政府债券发行规模,规范国债市场运行,调整国债投资规模与方向,促进我国经济长期稳定发展。     

风险资本规模与最优投资组合

对于任何一个风险投资基金来说,都涉及到投资组合规模问题。由于在投资策略中奉行积极干预的策略,风险投资家耗费了大量的精力和时间。因此,风险资本规模的扩大对风险投资家的投资结构可能会产生影响。这就引致出风险投资最优投资组合的问题,并涉及对风险投资收益率的影响。
