论按劳分配与按生产要素分配的结合

按劳分配与按生产要素分配之间既有差别，也存在共同之处。其差别主要体现在两种分配方式依据的理论以及二背后的所有制和经济体制不同。在我国当前的经济运行过程中，两种分配方式所依托的体制差异已不存在，并且传统的按劳分配所依据的理论在我国当前的体制下并不完全适用，两种分配方式也都承认劳动是人的谋生手段，劳动对劳动拥有所有权。因此，按劳分配与按要素分配之间的差别正在逐步消失，二之间能够相互渗透和兼容。从收入分配的目标来看，只有实行按劳分配与按生产要素分配的有机结合，才能实现高收入水平上的公平。     

四川省农业科研机构的产出能力测评

本文从四川省农业科研机构的产出能力入手来分析科研机构投入产出的效率及其影响因素,产出能力评价结果显示,四川省农业科研机构产出能力普遍较低并且差异巨大,差异主要来自于潜在产出能力;科研机构产出的现实能力和潜在能力不完全吻合.进一步分析投入产出之间的关系显示,产出的效率受到投入总量、投入结构、体制改革和机构内部管理四个要素的影响.     

外资进入和我国企业的生产率：“溢出”抑或“挤出”效应

我国改革和开放是同时推进的，引进了众多外资企业来推动我国经济发展。那么，外资企业的进入是否有助于我国内资企业的成长？本文分析我国工业企业超大样本数据，探讨外资进入的影响，研究我国内资企业的生产率能否向效率前沿收敛。结果发现，我国不同类型的内资企业均存在效率前沿的收敛趋势，内外资企业生产率差距不断缩小。外资进入对我国内资企业的短期影响主要表现为溢出效应，但是对于同行业的其他外资企业呈现挤出效应，特别是其他独资外企。我们进一步发现外资进入的长期影响是挤出效应，但是对于国有企业和民营企业的影响却不尽相同。     

道德哲学视域下的关公崇拜

在中国传统民间信仰之中,关公崇拜是俗文化兴起的产物,是社会道德情感社会潜意识孕育产生的一个道德模范,经典的三国演义为关公崇拜提供了有力的文本支撑,历代统治者的推波助澜也为这种崇拜发展起了重要作用。同时,关公崇拜背后有着深厚的道德内涵和社会价值,它所推崇的"义"是一种超越传统血亲关系的品德。这种品德即使在今天的商业社会也有着其存在发展的土壤,这也是关公崇拜得以延续至今的重要原因。     

Carbon and energy prices under uncertainty: A theoretical analysis of fuel switching with heterogenous power plants

European power producers have a major influence on the EU ETS, given that both their CO₂ emissions and their EUA (European Union Allowance) allocations account for more than half of the total volumes of the scheme. Fuel switching is often considered as the main short-term abatement measure under the EU ETS. It consists in substituting combined cycle gas turbines (CCGTs) for hard-coal plants in power generation. Thereby coal plants run for shorter periods, and CO₂ emissions are reduced. This paper provides the first theoretical analysis of fuel switching, in a context where power plants involved are not equally efficient. We begin with a preliminary work using illustrative examples and sensitivity analyses, which enables us to observe how differences in the efficiency of power plants impact the cost of fuel switching, and how this is related to the level of switching effort. Based on this, we build a theoretical model taking into account the effect of differences in the efficiency of power plants involved in fuel switching. We also investigate the effect of the timing of fuel switching abatements, within the temporally defined environment of our dynamic model. Results demonstrate that the gas price and uncontrolled CO₂ emissions act together on the carbon price. We show that the influence of the gas price on the carbon price depends on the level of uncontrolled CO₂ emissions, due to heterogeneity of power plants that are used in the fuel switching process. Furthermore, we show that the time of occurrence of uncontrolled emissions matters so that shocks have a stronger impact when they occur in a period that is closed to the end of the phase.     

Bribery,corruption and bureaucratic hassle: Evidence from Myanmar

Corruption has been found to be the most severe obstacle to business operations, according to a recent survey of over 3000 firms in Myanmar. This paper sets out to understand the structure of corruption through an econometric analysis of this survey. It finds that firms with higher ‘ability to pay’ (proxied by sales revenue and employee growth) are more likely to pay bribes. While firms with lower ‘refusal power’ (i.e. those dependent on bureaucratic permissions to export and import) are more likely to find corruption to be an obstacle. A distinct but related question is whether bribes act as ‘efficiency grease’ by allowing firms to circumvent red tape. No evidence is found to support this hypothesis; in fact, firms that pay bribes report greater bureaucratic hassle compared to firms that do not. This result fits in more closely with the view that red tape could be used to extract bribes from firms.     

The Practicality of Super Bowl Advertising for New Products and Companies

Abstract

Companies that advertise during the Super Bowl can reach 40 million U.S. households with a 30-second commercial spot, but the cost can exceed $2 million. This research examines Nielsen television ratings and expenses for related commercial spots and suggests that the Super Bowl is not always the best site for introducing new companies or products to the marketplace. ANOVA test results indicate that younger companies may better affect purchase decisions by advertising more frequently during less expensive programming slots.     

Information in generalized method of moments estimation and entropy-based moment selection

In this paper, we make five contributions to the literature on information and entropy in generalized method of moments (GMM) estimation. First, we introduce the concept of the long run canonical correlations (LRCCs) between the true score vector and the moment function f(_vt,_θ0)$f(v_t,{\theta }_0)$ and show that they provide a metric for the information contained in the population moment condition E[f(_vt,_θ0)]=0$\mathrm{E}[f(v_t,{\theta }_0)]=0$. Second, we show that the entropy of the limiting distribution of the GMM estimator can be written in terms of these LRCCs. Third, motivated by the above results, we introduce an information criterion based on this entropy that can be used as a basis for moment selection. Fourth, we introduce the concept of nearly redundant moment conditions and use it to explore the connection between redundancy and weak identification. Fifth, we analyse the behaviour of the aforementioned entropy-based moment selection method in two scenarios of interest; these scenarios are: (i) nonlinear dynamic models where the parameter vector is identified by all the combinations of moment conditions considered; (ii) linear static models where the parameter vector may be weakly identified for some of the combinations considered. The first of these contributions rests on a generalized information equality that is proved in the paper, and may be of interest in its own right.     

对于我国公平与效率关系的经济学思考

本文主要通过对我国公平与效率关系的描述及当前面临的现状的分析,运用帕累托效率的分析方法,得出公平与效率本质上具有一致性的结论,在此基础上提出公平与效率可以实现最优结合。我国目前正值“十一五”规划纲要的实施初期,大力发展和谐社会,应该在微观领域体现效率优先的原则,宏观领域公平优先的原则,来实现二者的最优结合。     

农村金融机构经营效率测算及影响因素的空间计量分析——兼论农村金融机构改革

农村金融改革的目标之一在于提升农村金融机构的经营效率,但相关研究较少考虑不良贷款约束,对农村金融机构经营效率及其影响因素的空间计量也很少涉及。基于此,本文以较具代表性的沿海地区G省为例,运用非径向EBM-Undesirable模型从多个视角测算分析了农村金融机构的经营效率,并基于空间相关性检验和空间计量模型,对经营效率进行了空间效应分析与影响因素估计。结果显示:农村金融机构经营效率总体水平较高,但起伏较大;农商行效率高于农信社,但2015年后差距有所缩小;经营效率具有空间相关性,经济水平、产业结构、行业竞争、资产规模和盈利能力是驱动因素,隐形风险是阻碍因素。鉴此,本文提出了加快推进农商行治理能力建设和产品服务创新、将经营效率作为农信社改制的重要参考指标、监管部门和省联社给予针对性经营指导、深化邻近协同经营等政策建议。
