The State Oil Fund of Azerbaijan is preparing for its 20th anniversary. However, there is nothing to celebrate: despite huge spending, the country’s role as an economic leader in the region is declining and people are suffering from poverty and poor social services. Oil and gas revenues have brought neither improved welfare nor democracy to Azerbaijan.
阿塞拜疆国家石油基金正在筹备成立20周年。然而,没有什么值得庆祝的:尽管花费巨大,该国作为该地区经济领导者的角色正在下降,人们正在遭受贫困和糟糕的社会服务。石油和天然气收入既没有给阿塞拜疆带来福利的改善,也没有带来民主。

We propose a model featuring horizon-specific mutual fund manager skill. Managers optimally choose their holdings based on their skill and the price impact of their trades. Fund turnover negatively correlates with the horizon over which value is added and positively correlates with price impact costs, while the correlation with fund size is ambiguous. We empirically evaluate the model using transaction-level data and decompose funds' value added based on the past length of funds' holdings. Holdings of high-turnover funds add a substantial amount of value in the first two months, while holdings of low-turnover funds only add value over longer horizons.
我们提出了一个具有特定领域共同基金经理技能的模型。经理们根据自己的技能和交易对价格的影响来选择最佳持仓。基金周转率与增值周期呈负相关,与价格影响成本呈正相关,而与基金规模的相关性不明确。我们使用交易级数据对模型进行实证评估,并根据基金持有的过去长度对基金的增值进行分解。持有高周转率基金会在头两个月增加大量价值,而持有低周转率基金只会在较长时间内增加价值。

Energy Poverty Measures and the Identification of the Energy Poor: A Comparison between the Utilitarian and Multidimensional Approaches in Chile 能源贫困措施和能源贫困的识别:智利功利主义和多维方法的比较

This work explores the consequences that different energy poverty definitions might have in the energy policy debate. We estimate the ten percent rule index (TPRI) while proposing and measuring a multidimensional energy poverty index (PMEPI). Both indices uses the 2017 National Survey of Public Perception on Energy applied to a sample of 3,500 households in Chile. Although both measures find that the energy poor represents about 15% of the population, energy poverty levels vary differently across the population depending on the employed measure. Moreover, the indices produce different energy poverty rankings across the territory, and most energy poor households are either TPRI poor or PMEPI poor. We found that this discrepancy between both energy poverty measures is mostly explained by territorylinked factors such as public lighting, service quality, service reliability, and thermal comfort. Consequently, an energy poverty analysis based solely on income or energy expenditure information (TPRI) is likely to neglect supply side constraints that are captured by the PMEPI. When identifying and targeting the energy deprived, the conclusion is that both energy poverty measures should not be used as substitutes but as complements.
这项工作探讨了不同的能源贫困定义在能源政策辩论中可能产生的后果。我们估计了10%规则指数(TPRI),同时提出并测量了多维能源贫困指数(PMEPI)。这两个指数都使用了2017年智利3500个家庭样本的公众能源认知全国调查。尽管这两项指标都发现能源贫困人口约占人口的15%,但能源贫困水平因所采用的指标而异。此外,这些指数在香港各地产生了不同的能源贫困排名,大多数能源贫困家庭要么是TPRI贫困家庭,要么是PMEPI贫困家庭。我们发现,两种能源贫困指标之间的差异主要是由公共照明、服务质量、服务可靠性和热舒适等与地域相关的因素来解释的。因此,仅基于收入或能源支出信息(TPRI)的能源贫困分析很可能忽视PMEPI所捕获的供应侧限制。在确定和针对能源匮乏人群时,结论是这两种能源贫困措施不应作为替代品,而应作为补充。

Extended Producer Responsibility in Singapore’s Resource Sustainability Act 新加坡资源可持续性法案中扩大生产者责任
Pub Date : 2019-10-24 DOI: 10.2139/ssrn.3474816
E. Bea, Melissa Low
With the introduction of the Resource Sustainability Act (RSA) on 5 August 2019, Singapore has embarked on its journey towards building a circular economy. Circularity was further emphasized and detailed in the Zero Waste Masterplan 2019 (ZWMP) launched on 30 August 2019. One of the main pillars of the Resource Sustainability Act (RSA) which was passed in Parliament on 4 September 2019, is the introduction of the Extended Producer Responsibility (EPR) scheme for electronic waste by 2021. Under the ZWMP, EPR will also be extended to packaging waste by 2025. This paper will review the consultative democratic exercise of the Year Towards Zero Waste (YTZW) that has shaped the RSA, the new e-waste EPR provisions in the RSA, as well as highlight the complexities in extending EPR to packaging waste.
随着2019年8月5日《资源可持续发展法案》(RSA)的出台,新加坡开始了建设循环经济的征程。2019年8月30日发布的《2019年零废物总体规划》(ZWMP)进一步强调并详细说明了循环性。2019年9月4日在议会通过的《资源可持续发展法案》(RSA)的主要支柱之一是在2021年之前引入电子废物的延伸生产者责任(EPR)计划。根据ZWMP,到2025年,EPR也将扩展到包装废物。本文将回顾“迈向零废物年”(YTZW)的协商民主实践,该实践形成了RSA, RSA中新的电子废物EPR条款,并强调将EPR扩展到包装废物的复杂性。

Legal Aspects of Economic Integration of West Africa 西非经济一体化的法律问题
Pub Date : 2019-10-21 DOI: 10.2139/ssrn.3470158

The historic signing of the African Continental Free Trade Area (AFCFTA) on 21 March 2018 marked a momentums milestone for regional economic integration in Africa. Despite the strong signals of commitment by policy makers and African leaders to regional economic integration, the process faces challenges such as limited energy and infrastructure development, insecurity and violent conflicts, multiple and overlapping membership of Regional Economic Communities (RECs), poor sequencing of the regional integration arrangements and limited financial resources (UN Economic Commission for Africa, Addis Ababa, 2019: Assessing Regional Integration in Africa (Part ix). Regional integration is now widely accepted as indispensable for expanding economic opportunities in Africa. African nations are vigorously pursuing an integration agenda in order to participate effectively in the globalization process. African leaders therefore view regional integration the most direct route to fast, broad-based economic development, an effective way to overcome the limitations of small internal markets and reducing the high rates of poverty and unemployment plaguing the continent. In view of the slow pace of continent-wide integration, African leaders have provided a framework for the implementation of the integration agenda. This framework is enshrined in the Abuja Treaty of 1991, which provides, inter alia, for the establishment of the African Economic Community (AEC), sets out its objectives and lay out six stages for the implementation of the integration agenda. Included in this framework is the critical role of African Regional Economic Communities (RECs), as the building blocks of the AEC in ensuring harmonization of their monetary, financial and payment policies, in order to boost intracommunity trade, establish a common market and to enhance monetary and financial cooperation among Member States. Accordingly, African leaders have firmly committed themselves to accelerating regional integration and cooperation. Underlying this commitment is a belief that most African countries cannot achieve rapid economic growth and development in a reasonable time without first overcoming the constraints of small economies and populations. Of the 54 African countries, 32 have populations of less than 15 million, while one third have populations of 3 million or less. Moreover, of the 46 least developed countries in the world, 31 are in Africa. Thus, the contribution of regional integration and cooperation to the promotion of intra-group trade, growth, development, social and political cohesion is unquestionable. Removal of border controls, harmonization of macroeconomic, sectoral and institutional policies and actions, liberalization of trade, free movement of people, goods, services and capital are expected to result in more efficient use of resources as well as in productivity and income gains. Participating countries are expected to fare better with integration than without it. T
2018年3月21日,非洲大陆自由贸易区(AFCFTA)的历史性签署标志着非洲区域经济一体化的一个里程碑。尽管政策制定者和非洲领导人对区域经济一体化发出了强烈的承诺信号,但这一进程仍面临挑战,如有限的能源和基础设施发展、不安全和暴力冲突、区域经济共同体(RECs)的多个和重叠成员、区域一体化安排的顺序不佳以及有限的财政资源(联合国非洲经济委员会,亚的斯亚贝巴,2019年:评估非洲的区域一体化(第九部分).区域一体化现在被广泛认为是扩大非洲经济机会所不可或缺的。非洲国家正在大力推行一体化议程,以便有效地参与全球化进程。因此,非洲领导人认为,区域一体化是实现快速、基础广泛的经济发展的最直接途径,是克服小型内部市场限制和降低困扰非洲大陆的高贫困率和高失业率的有效途径。鉴于整个大陆一体化进程缓慢,非洲领导人为执行一体化议程提供了一个框架。这一框架载于1991年的《阿布贾条约》,该条约除其他外规定建立非洲经济共同体(非洲共同体),规定其目标,并为执行一体化议程规定了六个阶段。该框架包括非洲区域经济共同体(RECs)的关键作用,作为AEC的基石,确保其货币、金融和支付政策的协调,以促进共同体内部贸易,建立共同市场并加强成员国之间的货币和金融合作。因此,非洲领导人坚定致力于加快区域一体化与合作。这一承诺的基础是一种信念,即大多数非洲国家如果不首先克服经济和人口小的限制,就无法在合理的时间内实现迅速的经济增长和发展。在54个非洲国家中,32个国家的人口不足1 500万,而三分之一的国家的人口在300万或以下。此外,在世界上46个最不发达国家中,有31个在非洲。因此,区域一体化与合作对促进集团内部贸易、增长、发展、社会和政治凝聚力的贡献是毋庸置疑的。取消边界管制,协调宏观经济、部门和体制政策和行动,贸易自由化,人员、货物、服务和资本的自由流动,预期将导致更有效地利用资源以及提高生产力和收入。参与国有望在一体化的情况下比没有一体化的情况下发展得更好。规模经济和节约成本安排所带来的生产率提高也可能加强产品和公司的内部和外部竞争力。经济收益反过来又可能促进政治和社会凝聚力和团结的进程。非洲联盟的成立和非洲发展新伙伴关系的通过,以及非洲国家成为世界贸易组织有效成员的强烈兴趣,都证明了非洲大陆努力实现经济和政治一体化,避免在全球被边缘化。它体现了非洲作为一个主要由最不发达和发展中经济体组成的大陆加速其变革的意愿。经济共同体同西非经共体一样,预期将发展成为自由贸易区、关税同盟,并通过横向协调和统一,最终形成一个包括整个大陆的共同市场和经济联盟。因此,在尼日利亚和多哥领导下,西非国家于1975年5月28日建立了西非国家区域经济共同体(西非经共体)。根据1975年的《西非经共体条约》,共同体的成员资格对所有西非国家开放,这一表述在《条约》中没有明确规定。虽然1993年经修订的西非经共体条约除其他外要求为实现非洲共同体的目标而追求经济一体化,争取建立一个共同市场和一个经济联盟,但是西非经共体区域在共同体个人和企业公民之间关于这一目标的信息严重不足。虽然许多人对1975年以来区域一体化议程实施的缓慢步伐表示怀疑,但另一些人则担心,进一步深化一体化可能带来的就业和市场竞争加剧的不利影响。 显然,必须在公众教育和宣传方面作出更大的努力。在此背景下,本文力求达到以下目标:1 .对“区域、贸易、市场、货币和金融经济、一体化”、“共同体法”和法律与政策的“协调”等相关关键术语进行概念澄清;2审查西非经共体区域经济一体化法律制度的性质和范围;3强调各成员国执行各项条约和西非经共体法律的重要性;四。最后是西非经共体的前进道路。

Credit Constraints and Human Capital Policies 信贷约束与人力资本政策
Pub Date : 2019-10-20 DOI: 10.2139/ssrn.3472750
Braz Camargo, G. Stein
We develop a model of voting behavior to show how credit constraints affect a society's demand for government spending on human capital policies, namely, public policies that increase the returns to human capital investments. The main result of the model is that a reduction in credit market frictions can increase the share of government spending on such policies, with a greater increase in poorer societies. We motivate our analysis by providing suggestive cross-country evidence that the composition of government spending is related to credit constraints and provide additional cross-country evidence in support of other predictions of the model.
我们开发了一个投票行为模型,以显示信用约束如何影响社会对政府在人力资本政策上支出的需求,即增加人力资本投资回报的公共政策。该模型的主要结果是,信贷市场摩擦的减少可以增加政府在此类政策上的支出份额,而在较贫穷的社会,这一比例的增加幅度更大。我们通过提供暗示性的跨国证据来激励我们的分析,这些证据表明政府支出的构成与信贷约束有关,并提供额外的跨国证据来支持模型的其他预测。

An Efficiency Paradox of Uberization 优步化的效率悖论
Pub Date : 2019-10-13 DOI: 10.2139/ssrn.3462912

Uberization promises to transform society based on an intuitive proposition: Advanced peer-to-peer matching guarantees greater overall efficiency. Here we show a paradox challenging this proposition in uberized ride-hail service, known as e-hail. By analyzing hundreds of local markets in Shenzhen, China, we discover e-hail is outperformed—in terms of wait time and trip production—by taxis hailed off street in areas with high densities of passengers and drivers. This paradox arises because a quicker match does not always expedite and enhance a service. On the contrary, it can induce competition that undermines the network effect, making a passenger less likely to benefit from more drivers, and vice versa, in e-hail than in taxi service. Consequently, simply attracting more users may not improve e-hail’s efficiency (defined as trip production at a given density of passengers and drivers), because its competitive edge diminishes with scale. The finding implies uberization has a limited impact on efficiency and is unlikely to create a “winner-take-all” in transportation.
优步化承诺基于一个直观的命题来改变社会:先进的点对点匹配保证了更高的整体效率。在这里,我们展示了一个挑战这一命题的悖论,在优步叫车服务中,被称为e-hail。通过对中国深圳数百个本地市场的分析,我们发现,在乘客和司机密度较高的地区,在等待时间和行程产出方面,e-叫车的表现优于出租车。之所以出现这种矛盾,是因为更快的匹配并不总是加快和增强服务。相反,它可能会引发竞争,破坏网络效应,使乘客不太可能从更多的司机中受益,反之亦然,在电子叫车服务中比在出租车服务中。因此,仅仅吸引更多的用户可能不会提高网约车的效率(定义为在给定的乘客和司机密度下的出行产量),因为它的竞争优势会随着规模的扩大而减弱。这一发现表明,优步化对效率的影响有限,不太可能在交通运输领域产生“赢家通吃”的局面。

How China Could Become a Net Exporter of Oil & Gas: Lessons Learned from International Tight Oil Development 中国如何成为油气净出口国:从国际致密油开发中吸取教训
Pub Date : 2019-10-01 DOI: 10.2139/ssrn.3468248
J. Pettit
Even with very aggressive growth assumptions for renewables, the role for oil and gas will grow, both in absolute terms and as a share of China’s total energy mix. And yet China’s domestic production of oil and gas continues to fall short and China’s need for expensive, foreign imports will only get worse. Meanwhile, the United States – once the world’s largest importer of oil – has become the world’s largest oil producer, with only one-half as many drilling rigs as China. The implications for China are profound. China has an enormous resource base – if China could apply the lessons learned from international development of tight oil and gas, and replicate the US success, it would reap tremendous benefits in terms of energy security, international trade, energy costs, and domestic industrial and economic development.
即使对可再生能源有非常积极的增长假设,石油和天然气的作用也会增加,无论是在绝对值上还是在中国总能源结构中的份额上。然而,中国国内的石油和天然气产量仍然不足,中国对昂贵的外国进口的需求只会变得更糟。与此同时,曾经是世界上最大的石油进口国的美国已经成为世界上最大的石油生产国,其钻井平台的数量只有中国的一半。这对中国的影响深远。中国拥有巨大的资源基础,如果中国能够借鉴国际上致密油和天然气开发的经验,并复制美国的成功,将在能源安全、国际贸易、能源成本、国内工业和经济发展方面获得巨大利益。

China has an enormous resource base – if China could apply the lessons learned from international development of tight oil and gas, and replicate the US success, it would reap tremendous benefits in terms of energy security, international trade, energy costs, and domestic industrial and economic development.","PeriodicalId":365767,"journal":{"name":"Sustainability & Economics eJournal","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122513391","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the years, Vietnam has a relatively high growth rate of gross domestic product (GDP) compared to other countries in the region, an average increase of 6.1% in the period of 2005-2016. However, the macro instability such as the budget deficit, public debt, the economy's debt is always high, the environment is more risky. In Vietnam, in the reports, even research articles are automatically admitted that the structure of Region II (industry and construction) and Region III (service) in GDP needs to grow and see it as an economic development in the right direction. From that, the idea of economic restructuring is to promote both Region II and Region III; The investment rate of this area is increasingly higher, if it is always very high in 2005 to 2015, it was around 43% in 2005 and nearly 50% in 2016, but the irony is that the value-added ratio compared to the value of production of this sector (region II) fell surprisingly fast; this ratio follows the structure of 2000, the structure of the input-output tables in 2007 of General Statistics Office of Vietnam) is 34.1%, in recent years (the structure of the new input-output tables) is only 21%. This means that this region is increasingly inefficient, resulting in an increasing amount of investment to compensate for that inefficiency. This research is based on Vietnam economic structure from the input-output table, 2012, that was published by Vietnam General Statistics Office, this research focused to analysis deeper on sectoral structure, inter-sectoral and effects induced impacts by final demand to output, value-added and greenhouse gas (GHG) emissions based on the approach of input-output analysis. This study hopes to help policymakers make rational decisions for sustainable development in Vietnam.
多年来,越南的国内生产总值(GDP)与该地区其他国家相比增长率相对较高,2005年至2016年期间平均增长6.1%。但是,预算赤字、公共债务等宏观不稳定,经济的债务始终居高不下,环境风险较大。在越南,在报告中,即使是研究文章也自动承认GDP中的区域II(工业和建筑)和区域III(服务)的结构需要增长,并将其视为经济发展的正确方向。由此可见,经济结构调整的思路是促进第二区域和第三区域的发展;该地区的投资率越来越高,如果说2005 - 2015年一直很高的话,2005年约为43%,2016年接近50%,但具有讽刺意味的是,该部门(II区)的增加值占产值的比例下降得惊人之快;这一比例遵循2000年的结构(2007年越南总统计局投入产出表的结构)为34.1%,近年来(新投入产出表的结构)仅为21%。这意味着该地区的效率越来越低,导致越来越多的投资来弥补这种效率低下。本研究以越南总统计局发布的2012年投入产出表中的越南经济结构为基础,基于投入产出分析的方法,重点深入分析了最终需求对产出、增加值和温室气体排放的部门结构、部门间和效应诱导影响。本研究希望能为越南的政策制定者做出合理的可持续发展决策提供帮助。

This study aims to examine the development and trend of countertrade transactions and assess their utility in state development by first examining the emergence and current trend of countertrade practice. It will then provide background on Congo and the events leading up to its current state of underdevelopment before presenting a case study on the Sino-Congolese countertrade deal, wherein both China and Congo’s stakes will be discussed, along with a comparison of this deal with another countertrade deal China has undertaken with a developing state. An examination of countertrade’s role in state development will follow. Finally, points will be made about some adverse effects of countertrade and its impression on the international community as a whole.
本研究旨在通过考察反贸易实践的产生和当前趋势来考察反贸易交易的发展和趋势,并评估其在国家发展中的效用。然后,本文将介绍刚果的背景和导致其目前欠发达状态的事件,然后介绍中刚反贸易协议的案例研究,其中将讨论中国和刚果的利害关系,并将该协议与中国与发展中国家签订的另一项反贸易协议进行比较。接下来将对反贸易在国家发展中的作用进行考察。最后,本文将阐述反贸易的一些不利影响及其对整个国际社会的影响。
