社会保障与区域经济互动机理及协调度研究

本文立足于社会保障与区域经济协调发展的作用机理,构建了反映社会保障与经济发展两大系统的指标体系及耦合协调模型,然后采用2008年的指标数据,计算并评价了各省市社会保障与经济发展两大系统的协调性。研究表明：社会保障与经济发展水平呈现显著的正相关关系,经济发展水平高的省份,其社会保障水平也相对较高,表现出明显的从东部到中西部的梯度递减趋势;东部地区省份和大部分中部地区省份,社会保障水平滞后于经济发展水平,而西部地区则与之相反,社会保障水平高于其经济发展水平;从协调度所属等级来看,类似于＂橄榄球＂状,优质协调和严重失调的省份较少,基本协调和轻度失调的较多,且东部地区协调度明显优于中、西部地区。     

Natural resources, capital accumulation and the resource curse

Early concern by economists for the effect of natural capital on economic growth gave way to complacency and neglect during the nineteenth century. Evidence has emerged, however, that since the 1960s the economic performance of low-income countries has been inversely related to their natural resource wealth. This relationship is not a deterministic one so policy counts. SEEA can help improve the policy and performance of resource-abundant low-income countries by reinforcing the rationale for the sound management of natural resources and also by providing an index of policy sustainability in the form of the net saving rate. This policy index, along with other measures such as a capital fund for sterilizing the rent, initiatives to increase the transparency of rent flows and the rigorous evaluation of alternative uses of additional public sector revenue can improve the efficiency by which natural resource rent is transformed into alternative forms of capital to sustain rising social welfare. Chad and Mauritania provide case studies to illustrate how SEEA and net saving can be used to diagnose policy failure and improve economic performance.     

社会保障缴费与财政投入的对策研究

构建和谐社会是未来相当长一段时期内我国社会主义现代化建设的基本目标，社会保障以其所具备的特殊的社会功能而对这一目标的实现起着特殊的作用。因此，社会保障制度中存在的一些不合理问题亟待改善。本文以我国国有企业为例，对国有企业的社会保障缴费能力、其职工的缴费能力及我国财政负担能力进行了实证分析，在得出相关结论的基础上，提出了四点建议：1．减轻企业的社会保障缴费负担；2．加大职工个人社会保障缴费率；3．加大财政对于社会保障的投入；4．加快社会保障立法步伐，促使社会保障制度尽快定型。     

Optimal social security tax with myopic agents

Myopic agents lack the foresight to save for their own old age. It is generally believed that correcting myopia is a rationale for a pay-as-you-go (PAYG) pension system. This view has been supported by existing literature showing that the optimal PAYG social security tax should increase when people are more myopic. In this paper we obtain new results opposed to the traditional view. By establishing a very standard general equilibrium OLG model with myopic agents and endogenized marginal product of capital, we show that the optimal social security tax should be lower when people are more myopic. Our numerical analysis also shows that the welfare cost of the social security tax increases with people's degree of myopia. These results suggest that correcting myopia is not a clear rationale for the PAYG social security.     

Governance structures in R&D networks: An analysis in the European context

This paper analyses governance structures used to organize partnerships in R&D networks using two approaches: transaction costs theory and social capital theory. We argue that these theories are complementary; this explains forms of governance through the degrees of administrative (structural and safeguard mechanism) and social factors (cohesion and openness) they embody. Data was obtained from European R&D networks created through Framework Programmes which include a great number of universities, non profit institutions and firms. Findings show the variables that characterize and explain the governance forms based on the applicability of R&D networks. This study not only provides a theoretical model for analysing governance structures of these networks, but is also useful for both improving the management of networks and for fostering collaboration at an international level.     

Why Punish? Social reciprocity and the enforcement of prosocial norms

Recently economists have become interested in why people who face social dilemmas in the experimental lab use the seemingly incredible threat of punishment to deter free riding. Three theories with evolutionary microfoundations have been developed to explain punishment. We survey these theories and use behavioral data from surveys and experiments to show that the theory called social reciprocity in which people punish norm violators indiscriminately explains punishment best.JEL Classification: C91, C92, D64, H41 Correspondence to: Jeffrey P.

Is group selection necessary? An alternative interpretation of homogeneous Middleman groups: Comments on Janet Landa’s paper

This article critiques the efforts by Janet Landa, David Sloan Wilson and others to use group selection paradigms to explain the success of homogenous middlemen groups (HMGs). It argues that group selection theory cannot explain the conflicts of interests that arise within HMGs or why they dissolve in certain occasions. Landa’s earlier explanations, which stressed the combination of genetic (kinship) and social bonds in the creation of trust and cooperation in the extension of credit and the creation of local public goods, better predicts both the strength and weaknesses of HMGs.      

A functional approach for studying technological progress: Extension to energy technology

This paper extends a broad functional category approach for the study of technological capability progress recently developed and applied to information technology to a second key case—that of energy based technologies. The approach is applied to the same three functional operations—storage, transportation and transformation—that were used for information technology by first building a 100 plus year database for each of the three energy-based functional categories. In agreement with the results for information technology in the first paper, the energy technology results indicate that the functional approach offers a stable methodology for assessing longer time technological progress trends. Moreover, similar to what was found with information technology in the first study, the functional capability for energy technology shows continual—if not continuous—improvement that is best quantitatively described as exponential with respect to time. The absence of capability discontinuities—even with large technology displacement—and the lack of clear saturation effects are found with energy as it was with information. However, some key differences between energy and information technology are seen and these include:

?

Lower rates of progress for energy technology over the entire period: 19-37% annually for Information Technology and 3-13% for Energy Technology.

?

Substantial variability of progress rates is found within given functional categories for energy compared to relatively small variation within any one category for information technology. The strongest variation is found among capability progress among different energy types.

?

More challenging data recovery and metric definition for energy as compared to information technology.

These findings are interpreted in terms of fundamental differences between energy and information including the losses and efficiency constraints on energy. We apply Whitney's insight that these fundamental differences lead to naturally modular information technology artifacts. The higher progress rates of information-based as opposed to energy-based technologies follows since decomposable systems can progress more rapidly due to the greater ease of independent as opposed to simultaneous development. In addition, the broad implications of our findings to studies of the relationships between technical and social change are briefly discussed.     

从“有限理性＋社会人”的模式中恩考反腐倡廉工作——读《转型期防止腐败的综合战略与制度设计》后的思考

中国从计划经济向市场经济转变的过程中出现了政府职能的转变不能及时满足经济发展和社会发展的需要，从而导致了很多问题的出现。而腐败问题尤为突出，解决好了此问题为政府的职能转变将会有很大的推动作用。有很多学者对中国的腐败问题提出了自己的看法，本文对《转型期防止腐败的综合战略与制度设计》提出的对腐败问题的治理办法进行分析，运用西蒙的决策理论和人际学说的社会人的理论，提出用“有限理性＋社会人”的模式补充只重视制度建设来解决腐败问题的不足。
