Smart city networks' governance: The Spanish smart city network case study

The governance of smart city networks emerges as a new research area intersecting smart governance and public networks studies. This work aims to contribute to the literature on smart cities governance by studying councillor's governance in complex networks and on network performance. To carry out this analysis, the Spanish Network of Smart Cities (RECI), one of the first of its kind and an international reference for city networks, is reviewed as a case study, with the main objective of establishing a theory on its global innovation capacity and operations, together with the local level spurring influenced on its members. A PEST (Political, Economic, Social and Technological) analysis was carried out in order to assess the impact of the smart city network both at local, national and international level. This research was completed with a consultation carried out among some of RECI's municipalities. The analysis of the results shows how RECI can be considered an example of a well organised network with quantifiable savings for its members, capable of configuring future policies in local administration, necessarily related to efficiency, digitalization and citizen-centricity and with key topics to build the future. The study also suggests recommendations oriented to potential improvements that smart city networks could undertake.     

Insurance Considering a New Stochastic Model for the Discount Factor

In many empirical situations (e.g.: Libor), the rate of interest will remain fixed at a certain level (random instantaneous rate i i ) for a random period of time ( t i ) until a new random rate should be considered, i i + 1 , that will remain for t i + 1 , waiting time until the next change in the rate of interest. Three models were developed using the approach cited above for random rate of interest and random waiting times between changes in the rate of interest. Using easy integral transforms (Laplace & Fourier) we will be able to calculate the moments of the probability function of the discount factor, V ( t ), and even its c.d.f. The approach will also be extended to the calculation of the expected value (net premium) and variance of a term insurance and we will get its c.d.f., something not very common in actuarial literature due to its complexity, but very useful when the law of large numbers cannot be applied and consequently use normal approximations.     

Everybody wins? A discourse analysis of competing stakeholder expectations in Social Impact Bonds

ABSTRACT

This paper explores how diverse stakeholders frame their expectations of Social Impact Bonds (SIBs). Using discourse analysis, the authors examine competing expectations in SIB press releases, showing how they differ between stakeholders, between institutional contexts, and how they evolve over time. The paper highlights how the prioritization of social finance and collaboration discourses privileges the role of private investors, which in turn diminishes the role of service providers as innovators.

我国外汇储备货币组合的实证分析

截至2006年2月我国外汇储备达8536亿美元,超过日本成为世界外汇储备持有量第一大国,其后我国外汇储备也呈不断增长的态势,到2007年3月已达12020.31亿美元.外汇储备的持续增加意味着面临的风险也在持续增加.因此,如何确定合理的外汇储备币种组合成为目前需要迫切研究的课题.本文根据国内外已有研究确定了外汇储备货币结构的影响因素,结合因子分析法,得出了我国外汇储备币种组合的新选择,提出了我国外汇储备货币组合的对策建议.     

地方公共服务、要素流动与要素空间配置——基于本地交易成本的均衡分析

通过"两区域、两要素与两部门"模型研究发现,即使存在区域内与区域间两类交易成本,增加公共服务仍有利于吸引要素流入,并产生要素空间聚集效应;增加公共支出以改善区内贸易条件对要素流动及其空间分布具有不同的影响;我国地方公共支出规模与全要素生产率之间存在明显的长期因果关系.     

中国居民消费价格指数预测

2012年下半年,中国居民消费价格指数将保持在2%左右,不会发生大的通货膨胀和通货紧缩。为避免价格大起大落,实现经济可持续发展,要坦然面对居民消费价格指数的低位运行,积极扩大消费需求;通过立法和政策引导,鼓励企业诚信经营,生产出消费者需要且信赖的产品;大力淘汰落后产能,促进行业结构调整优化和整体竞争力的提升。     

WHAT MAKES A GREAT JOURNAL GREAT IN ECONOMICS? THE SINGER NOT THE SONG

Abstract This paper analyses what makes a great journal great in economics. Alternative research assessment measures (RAM) are discussed, with an emphasis on the Thomson Reuters Institute for Scientific Information (ISI) Web of Science database. ISI RAM that are calculated annually or updated daily are defined, including the classic 2‐year impact factor (2YIF), 5‐year impact factor (5YIF), immediacy (zero‐year impact factor (0YIF)), eigenfactor score, article influence, citation performance per paper online, h‐index, Zinfluence, PI‐BETA (papers ignored ‐ by even the authors) and two new RAM measures, self‐citation threshold approval rating and impact factor inflation. The data are analysed for the most highly cited journals in economics, management, business and business–finance on the basis of 2YIF. In addition to evaluating research in the most highly cited journals in economics, management, business and business–finance, the paper evaluates alternative RAM, highlights similarities and differences in RAM criteria, finds that several RAM capture similar performance characteristics, and finds that immediacy and PI‐BETA are not highly correlated with other RAM. Harmonic mean rankings of the 12 RAM criteria are also presented. Emphasizing 2YIF to the exclusion of other useful RAM criteria can lead to a distorted evaluation of journal performance and influence.     

The use of ex-ante modelling tools in European Impact Assessment: What role does land use play?

Impact Assessment was introduced by the European Commission in 2002 in order to make policy development more transparent and improve the ‘quality’ of European policies. Cross-sectoral consultation, broad participation and the quantitative assessment of the impacts of policies are significant elements of this process. This article specifically addresses the role of tools modelling the impact of policies on land use in Impact Assessment. The choice of a specific modelling tool is conceptualised as an action situation interlinked with other action arenas. The article aims to uncover the institutions structuring the action situation. The outcome of the empirical work suggests that two types of Impact Assessments can be distinguished. Impact Assessments either substantively contribute to the specific policy that the Commission proposes or they legitimise policy choices ex post that have already been adopted. The legislative procedure that applies to a specific policy sector, the policy making culture in the DG and the stakes that are at issue seem to influence whether Impact Assessments contribute to policy development, or legitimise it. Furthermore, the article describes the situation in which desk officers choose a modelling tool throughout Impact Assessment. To advance their careers desk officers aim to produce policy proposals which respond to the issues raised by the actors involved in Impact Assessment and specifically in policy development and, later on, adoption. Therefore, desk officers’ preferences are shaped by the community that is involved in policy development and Impact Assessment. The article describes what role modelling tools play in European Impact Assessment procedures and it names the heuristic of criteria which desk officers use to choose a modelling tool. Besides several technical and data problems of modelling land use impact, it seems to be unlikely that land use will become a significant dimension of Impact Assessment and modelling as it is confronted with an unfavourable institutional environment at the European level.
