区域“大众创业，万众创新”效率评价

以中国内地31个省（市）数据为基础,以“大众创业,万众创新”（简称“双创”）的本质及特征为依据,构建了一套区域“双创”效率评价指标体系。运用三阶段DEA方法,在控制环境因素的基础上考察了各地区“双创”投入产出转化效率。研究显示,目前各区域“双创”效率发展不均衡,规模效率和纯技术效率除个别地区达到1以外,其它地区都存在不同程度的效率缺损。最后,根据规模效率和纯技术效率大小,对31个省市的“双创”效率进行四分图归纳,根据归纳结果提出了相应的解决措施,可为“双创”可持续发展提供参考依据。

Resource-envy-free and efficient allocations: A new solution for production economies with dedicated factors

I consider the problem of determining an equitable and efficient allocation of resources in production economies with factors which must be dedicated to production and cannot be consumed directly. First, I show that in such economies envy-free and efficient allocations exist under standard assumptions. However, I argue this notion of fairness is unsuitable for the present context. I then introduce a new notion of fairness, which I call resource-envy-freeness. First, I associate with each consumption bundle its resource footprint consisting of the vector of factors used to produce it. I then show that preferences over consumption bundles can be extended to preferences over factor bundles. An allocation is resource-envy-free if no agent prefers another agent’s resource footprint to its own. The analysis of resource-envy-free allocations in production is exactly analogous to the analysis of envy-free allocations in exchange. I establish that resource-envy-free and efficient allocations exist under standard assumptions, and I demonstrate that such allocations are intuitively appealing.

Farsighted strategies in the formation of a communication network

I examine the formation of a specific communication network, a variant of the two-way flow model, in which agents have farsighted strategies. I show that the likelihood to form efficient networks tends to zero for sufficiently large network sizes.     

Intergenerational Earnings Inequality: New Evidence From Italy

Using an innovative dataset built by merging survey and administrative data, we provide new estimates of intergenerational earnings’ inequality between fathers and sons in Italy, extending previous evidence in several directions. We rely on the TSTSLS method to predict fathers’ earnings and compute intergenerational elasticities and imputed rank–rank slopes, trying to reduce estimation biases. Confirming previous evidence, we find that Italy is characterized by a high intergenerational inequality in cross-country comparison. Extending previous analyses, we show that the intergenerational association increases when sons at older ages and multi-annual averages of pseudo-fathers’ and sons’ earnings are considered. We also find that the intergenerational persistence differs across geographical macro-areas and is high also for daughters, especially when family earnings are considered. Furthermore, estimates where possible mediating factors of the parental influence are included among the covariates show that a high intergenerational association persists when sons’ education and occupation are controlled for.     

基于DEA方法的中国农业水资源利用效率研究

[目的]以我国各省市2008~2015年农业水资源利用效率为研究对象,探究我国农业水资源利用效率的规律与特点,并基于此提出促进农业水资源合理利用的建议。[方法]主要采用了文献研究法、统计分析法和数据包络分析(DEA)法。通过文献搜集我国各省市2008~2015年与农业水资源利用相关的数据,构建DEA模型,对我国近年来农业水资源利用效率进行评价。[结果]2008~2015年,我国农业水资源利用效率在0.80上下浮动。各省市农业水资源利用效率随时间变化趋势不同。甘肃和上海的农业水资源利用效率涨幅最大,年增长率分别为4.39%和2.74%;山西、江西以及陕西省的农业水资源利用效率整体趋于下降;浙江、湖南以及陕西和新疆的农业水资源利用效率有先上升后下降的特点,表现出明显的波动。此外,农业水资源利用效率区域分化明显。东部地区农业水资源利用效率一般高于0.80,中部地区位于0.60~0.80,西部地区农业水资源利用效率一般低于0.60。[结论]2008~2015年,我国农业水资源利用效率表现出一定的时间差异性和空间差异性。时间差异性:我国农业水资源利用效率一直处于较高水平并呈现逐年增长趋势,不同省份的农业水资源利用效率随时间变动趋势各异。空间差异性:东部地区农业水资源利用效率最高,中东部地区农业水资源利用效率甚至达到了最优,中部地区其次,西部省区农业水资源利用效率最低。农业水资源利用效率受当地政策、经济发展水平、农业发展水平、水资源总量和人口压力等因素影响严重,今后应针对不同地区采取不同措施解决实际问题。

山东省农地面积较广,利用类型丰富,农地的合理利用对推进山东省农业经济发展及土地资源的可持续发展具有重要意义。文章阐述了山东省农地利用状况,从自然因素、土地投入、农业土地利用结构、农业从业人员素质、农产品市场意识及经营手段等方面探讨影响农地利用经济效益的因素,通过构建DEA模型,对农地利用经济效益进行应用分析,并提出加大农业用地投入和建设、优化农业用地结构和规模、强化市场经营意识和管理等提高山东省农地利用经济效益的对策建议,以期为山东省土地合理规划利用提供理论依据。     

Efficiency in the provision of social care for older people. A three-stage Data Envelopment Analysis using self-reported quality of life

Using a three-stage data envelopment analysis approach, this paper explores efficiency in the provision of social care for older people in 148 English Councils in 2009/10. Departing from D'Amico and Fernández (2012) [31] our measure of efficiency is inscribed within the production of welfare framework and based on self-reported quality of life of recipients of the services. Our results indicate a high level of efficiency, but once we control for the effects of a number of environmental variables, we found that more stringent eligibility criteria and higher assessment costs are negatively associated with the efficiency in the provision of social services.     

The effect of sporting success and management failure on attendance demand in the Bundesliga: a revealed and stated preference travel cost approach

This study examines the private consumption benefits of sports attendance using revealed and stated preference data from 28 Football Bundesliga teams across three divisions. Survey respondents were presented with positive (sporting success) and negative (management failure) scenarios and asked for the number of game trips if each scenario occurred. The results of a pooled random effects Poisson model show that travel costs and ticket price have a significant negative effect on the number of home game trips. The weighted consumer surplus per game trip including travel costs and ticket prices is €345. Consumer surplus per game trip was found to change by €41 (first division) and €98 (second and third division) if the positive scenario occurred and by €39 if the negative scenario occurred.
