This study aims to figure out what factors influence environmental degradation as measured by the ecological footprint in Algeria. It examines the impact of financial development (access to credit), human capital (education), and economic growth on Algeria's environmental deg- radation in the short and long term. For this purpose, the current study examines short- and long-term consequences using a 37 years time series of secondary data and applies the "autoregressive distributed lag" time-series model. Our findings show that economic growth has a considerable positive impact on the ecological footprint in both the long and short term. Both access to credit and education have a negative effect on environmental degradation. This sug- gests that access to credit and education are both negative short- and long-term derivatives of the ecological footprint in Algeria, whereas economic growth is a positive short- and long- term indicator. Furthermore, bidirectional causality is discovered between access to credit and ecological footprint, while the granger causality method discloses unidirectional causality from economic growth to the ecological footprint. Education also Granger-causes ecological footprint without any feedback. The current research has significant consequences since it will assist Algerian policymakers in controlling environmental deterioration through improved regulations. The findings inspire Algerian authorities to encourage the human resource to adopt green development through proper education programmes. Additionally, investors should be encouraged to finance environmentally friendly, sustainable projects. Furthermore, in Algeria, the government should reduce pollution from production by implementing green technologies. And participate in an international development track that is focused on longterm sustainability.
本研究旨在找出影响阿尔及利亚生态足迹测量的环境退化的因素。它考察了金融发展(获得信贷)、人力资本(教育)和经济增长对阿尔及利亚短期和长期环境退化的影响。为此,本研究使用37年的二次数据时间序列来检验短期和长期后果,并应用“自回归分布滞后”时间序列模型。我们的研究结果表明,经济增长对生态足迹在长期和短期内都有相当大的积极影响。获得信贷和教育对环境退化都有负面影响。这表明,获得信贷和教育是阿尔及利亚生态足迹的短期和长期负面衍生品,而经济增长是一个积极的短期和长期指标。此外,信贷获取与生态足迹之间存在双向因果关系,而格兰杰因果关系方法揭示了经济增长与生态足迹之间的单向因果关系。教育也会在没有任何反馈的情况下造成生态足迹。目前的研究具有重要意义,因为它将帮助阿尔及利亚决策者通过改进法规来控制环境恶化。调查结果激励阿尔及利亚当局通过适当的教育方案鼓励人力资源采用绿色发展。此外,应鼓励投资者为环境友好、可持续的项目提供资金。此外,在阿尔及利亚,政府应该通过实施绿色技术来减少生产中的污染。并参与以长期可持续性为重点的国际发展轨道。

Every power producer is facing the risk of an adverse price movement of commodities used for the power production and power itself in the meantime between cash flow planning and the actual power production. This study analyzes process of hedging the commodity market risk with usage of derivatives with financial settlement as an alternative to physical ones. For this purpose a hypothetical power producer operating a gas power unit was selected. Based on the real Czech power market data of 2019 this paper simulates expected cash flow, assesses potential risk for the producer and compares real cash flow of an unhedged position with a position hedged via futures contracts and spread options with financial settlement. For the risk evaluation Monte Carlo simulation and value at risk methods are used. As the most effective way to hedge the market risk of 2019 proved itself the futures hedge with monthly hedging tenor with an alternative in a short call option position. Practical implications: The study is written in a practical approach to the market risk man- agement process so that could be applicable in any company active in the power market facing the risk of commodity price movements regardless the input commodity used for the electric- ity production. Using the data of the Czech power market of 2019 the paper presents the case of a real power market participant.
在现金流规划和实际电力生产之间,每个电力生产商都面临着用于电力生产的商品和电力本身的不利价格变动的风险。本研究分析了使用金融结算替代实物结算的衍生品对冲商品市场风险的过程。为此,选择了一个运行燃气发电机组的假想发电厂。基于2019年捷克电力市场的实际数据,本文模拟了预期现金流,评估了生产商的潜在风险,并将未对冲头寸的实际现金流与通过期货合约和价差期权对冲的头寸进行了比较。风险评估采用蒙特卡罗模拟和风险价值法。作为对冲2019年市场风险的最有效方式,事实证明,期货对冲具有每月对冲期限,并在短期看涨期权头寸中提供替代方案。实际意义:该研究以市场风险管理过程的实用方法编写,适用于任何活跃在电力市场中面临商品价格波动风险的公司,无论电力生产所用的投入商品是什么。利用2019年捷克电力市场的数据,本文介绍了一个真实的电力市场参与者的案例。

A perspective of global biofuel policies 全球生物燃料政策展望
Q4 Economics, Econometrics and Finance Pub Date : 2022-03-01 DOI: 10.3280/efe2021-002003
Sudip Das
Biofuels have drawn the attention of policymakers as a medium to address concerns of energy security, climate change and socio-economic development. The paper examines the biofuel policies of the major biofuel producing nations and analyzes the key instruments being adopted by them during the last decade such as blending mandates, financial incentives, subsidies, import tariffs, greenhouse gas (GHG) emission and carbon trading. The countries are categorized by continent and covers Asia (India, China, Malaysia, Indonesia and Thailand), Europe (European Union, Germany and France), South America (Brazil, Argentina), North America (USA, Canada) and Australia. The paper assesses whether the blending mandates had the desired impact on realization of policy targets and examines the impact of biofuel policies on the socio-economic development and environmental sustainability in these nations. Most countries continue to use sugarcane, corn, grains, and vegetable oils as feedstock for biofuel production thereby raising concerns about their adverse impact on food prices and food availability to the underprivileged people. Biofuel policies for this paper refer to policy instruments, strategies and programs which were established to aid and manage the production and consumption of biofuels - both ethanol and biodiesel.
生物燃料作为一种解决能源安全、气候变化和社会经济发展问题的媒介已经引起了决策者的注意。本文考察了主要生物燃料生产国的生物燃料政策,并分析了它们在过去十年中采用的关键工具,如混合指令、财政激励、补贴、进口关税、温室气体排放和碳交易。这些国家按大陆分类,包括亚洲(印度、中国、马来西亚、印度尼西亚和泰国)、欧洲(欧盟、德国和法国)、南美(巴西、阿根廷)、北美(美国、加拿大)和澳大利亚。本文评估了混合指令是否对政策目标的实现产生了预期的影响,并考察了生物燃料政策对这些国家的社会经济发展和环境可持续性的影响。大多数国家继续使用甘蔗、玉米、谷物和植物油作为生物燃料生产的原料,从而引起人们对它们对粮食价格和贫困人口粮食供应的不利影响的担忧。本文的生物燃料政策是指为帮助和管理生物燃料(包括乙醇和生物柴油)的生产和消费而制定的政策工具、战略和计划。

Can income growth alone increase household consumption of cleaner fuels? Evidence from Pakistan 仅靠收入增长就能增加家庭对清洁燃料的消费吗?来自巴基斯坦的证据

Consumption of solid fuels by households is a major cause of indoor air pollution (IAP) and can severely damage health and the environment. The Environmental Kuznets Curve (EKC) literature suggests that as poor and middle-income countries grow, households will climb the ‘energy ladder' and adopt cleaner fuel technologies. This paper critically assesses that claim, using data from the Pakistan Social and Living Standards Measurement (PSLM) Survey 2013- 14. A novel aspect of our study is that, rather than treating the choice to use each fuel type as independent, we instead focus on the households' choice of fuel mix, using cluster analysis to determine in a data-driven way the fuel mixes that households actually employ. Importantly, despite income being a strong determinant of fuel mix selection, we show that income growth alone is unlikely to lead to substantial uptake of cleaner fuels. Our results challenge a practical aspect of countries moving along the EKC, and suggest that in order to reduce IAP direct policy intervention will be required.
家庭使用固体燃料是室内空气污染的一个主要原因,可严重损害健康和环境。环境库兹涅茨曲线(EKC)文献表明,随着贫困和中等收入国家的增长,家庭将攀登“能源阶梯”并采用更清洁的燃料技术。本文使用2013- 14年巴基斯坦社会和生活水平测量(PSLM)调查的数据,对这一说法进行了批判性评估。我们研究的一个新颖方面是,我们不是将使用每种燃料类型的选择视为独立的,而是将重点放在家庭对燃料组合的选择上,使用聚类分析以数据驱动的方式确定家庭实际使用的燃料组合。重要的是,尽管收入是燃料组合选择的重要决定因素,但我们表明,仅靠收入增长不太可能导致大量使用清洁燃料。我们的结果挑战了沿着EKC移动的国家的实际方面,并建议为了减少IAP,需要直接的政策干预。

This study investigates the preferences of Italian home-owners when choosing to buy wood for home heating systems. The focus is on understanding the influence of different dimensions of sustainability on consumer choices. For this purpose, we designed a survey including a discrete choice experiment and administered it to residents in Italy. Our findings reveal that, on average, respondents pay particular attention to wood cultivation systems. However, forest property regime was considered second in terms of importance after wood price. Further analysis found that our sample presents four clusters of wood consumers. These findings showed considerable heterogeneity among respondents, the majority of whom considered important wood cultivation practices and appreciated forest landscape beauties for their decision. Local origin of wood was considered important by the majority of respondents, even if, surprisingly, a group of interviewees preferred foreign wood. To achieve better results and effectiveness in improving sustainable practices of the domestic heating systems, a combination of policies should be used simultaneously. Our results support the hypothesis that policymakers could achieve better results in terms of sustainability by applying a combined policy that levers the importance citizens accord to the different characteristics of wood in home heating systems.
本研究调查了意大利房主在选择为家庭供暖系统购买木材时的偏好。重点是了解可持续性的不同维度对消费者选择的影响。为此,我们设计了一项包括离散选择实验的调查,并对意大利的居民进行了调查。我们的研究结果表明,平均而言,受访者特别关注木材栽培系统。然而,森林财产制度被认为在重要性方面仅次于木材价格。进一步分析发现,我们的样本呈现出四组木材消费者。这些发现显示了受访者之间相当大的异质性,他们中的大多数人在做出决定时考虑了重要的木材种植实践和欣赏森林景观之美。大多数受访者认为木材的本地来源很重要,即使令人惊讶的是,一组受访者更喜欢外国木材。为了在改进家庭供暖系统的可持续做法方面取得更好的结果和效果,应同时使用多种政策。我们的研究结果支持这样一个假设,即政策制定者可以通过采用一项综合政策,利用公民对家庭供暖系统中木材不同特征的重要性,在可持续性方面取得更好的结果。

This article is devoted to an analysis of the prospects for the development of hydrogen uses, from a decarbonisation perspective. Based on a comparison of low-carbon hydrogen production technologies (from renewables, nuclear, CCS) and their prospective costs, a «merit order» in the uses is determined, leading to prioritise substitution in heavy industry first, then in heavy transport. We also draw attention to the safety of hydrogen uses, whose explosiveness calls for the greatest vigilance, at the risk, otherwise, of hindering the deployment of hydrogen uses

Electricity availability and generation have a significant impact on the economies internationally. Understanding the factors affecting the electricity supply sector is imperative towards improving the industry and achieving a sustainable energy future for all as per the United Nations Sustainable Development Goals (SDGs) to 2030. This study mainly focuses on the institutional quality factors that impact the electricity supply of twenty countries, representing various electricity market structures and supply mixes, to derive holistic policy suggestions. Institutional quality will be defined as property rights, corruption perception, voice and accountability, government efficiency, the rule of law and regulatory quality in the study. To do so, a Seemingly Unrelated Regression model will be used for the period 2003 to 2018. The results indicate that improved institutional quality stabilises markets, affecting the electricity supply.
电力供应和发电对国际经济产生重大影响。根据联合国2030年可持续发展目标(sdg),了解影响电力供应部门的因素对于改善该行业和实现所有人的可持续能源未来至关重要。本研究主要关注影响二十个国家电力供应的制度质量因素,代表不同的电力市场结构和供应组合,以得出整体的政策建议。在研究中,制度质量将被定义为产权、腐败感知、发言权和问责制、政府效率、法治和监管质量。为此,将在2003年至2018年期间使用看似无关的回归模型。结果表明,制度质量的提高稳定了市场,影响了电力供应。

The study investigates the impact of renewable energy, international trade, foreign direct investments (FDI), and carbon dioxide emissions on gross domestic product growth (GDPG) by adopting the autoregressive distributed lag approach, error correction method, and Toda- Yamamoto approaches to determine the long-term relationship, short-term relationship, and direction of causality for the period 1984 to 2018 in Nigeria. The results of the study show the existence of a long-term and short-term relationship among the variables. The study found positive relationships between GDPG, international trade and carbon dioxide emissions. The Toda-Yamamoto tests also found a unidirectional causality from gross domestic growth to international trade and carbon dioxide emissions. On the other hand, the GDPG has a positive and insignificant relationship with renewable energy and foreign direct investment in the long term and short term. The study also found no causality between FDI, GDPG, and renewable energy. Therefore, based on the findings, this study puts forward policy strategies that are likely to reduce emissions without reducing GDP growth in Nigeria and other developing countries.
本研究采用自回归分布滞后法、误差校正法和Toda-Yamamoto方法,研究了可再生能源、国际贸易、外国直接投资(FDI)和二氧化碳排放对国内生产总值增长的影响,以确定长期关系、短期关系,以及尼日利亚1984年至2018年期间的因果关系方向。研究结果表明,变量之间存在长期和短期的关系。研究发现GDPG、国际贸易和二氧化碳排放之间存在正相关关系。Toda-Yamamoto测试还发现了从国内总增长到国际贸易和二氧化碳排放的单向因果关系。另一方面,GDPG与可再生能源和外国直接投资在长期和短期内都有着积极而微不足道的关系。研究还发现,外国直接投资、GDPG和可再生能源之间没有因果关系。因此,基于这些发现,本研究提出了可能在不降低尼日利亚和其他发展中国家GDP增长的情况下减少排放的政策策略。

We study the determinants of a stable long-run relationship between energy use and economic growth. We select a sample of 72 countries and test the cointegration between energy consumption and GDP. Next, we estimate the probability of cointegration using characteristics of countries' energy matrix and economic activities. Our findings indicate a lower probability of cointegration between energy use and income in countries with a larger service sector and in countries where energy matrices have greater use of renewable sources. Also, we find a higher probability of cointegration in countries with intense use of nuclear power.
我们研究了能源使用和经济增长之间稳定的长期关系的决定因素。我们选取了72个国家的样本,检验了能源消费与GDP之间的协整关系。接下来,我们利用各国能源矩阵和经济活动的特征来估计协整的概率。我们的研究结果表明,在服务业规模较大的国家和能源矩阵更多地使用可再生能源的国家,能源使用与收入之间的协整概率较低。此外,我们发现在核电使用密集的国家协整的可能性更高。
