This study aims to examines the dynamic effects of economic performance on credit ratings in Egypt during the period (1996-2018) consisting of quarterly observations for each variable. The study adopted the ARDL bounds testing approach to establish these relationships which showed that there exists a positive short run and long-run relationship between the credit rating, (GDP) growth domestic product and (FDI) foreign direct investment, while there are significant negative relationships in both short and long run between budget deficit, external debt, exchange rate and the credit rating. This result implies that GDP, FDI, foreign reserve and budget deficit are essential macroeconomic variables that influence the economic performance and the credit rating in Egypt.
本研究旨在研究1996-2018年期间埃及经济表现对信用评级的动态影响,包括对每个变量的季度观察。本研究采用ARDL边界检验方法建立了这些关系,结果表明信用评级、(GDP)增长国内生产总值和(FDI)对外直接投资之间存在着短期和长期的正相关关系,而预算赤字、外债、汇率与信用评级之间存在着短期和长期的显著负相关关系。这一结果表明,国内生产总值、外国直接投资、外汇储备和预算赤字是影响埃及经济表现和信用评级的重要宏观经济变量。

To prevent counterfeiting, control supply, and ensure the legitimacy of asset transfers, e-currency makes use of cryptography. The primary focus is on the profitability and volatility of Bitcoin trading. The volatility of an investment can be estimated by calculating its standard deviation in terms of logarithmic returns. The researchers in this study employed the specific test to check for data normality. The results of a plot, a statistical process control chart, and other analyses all pointed to significant fluctuations. More and more people place a premium on uncertainty. Investors are wary of Bitcoin at the moment due to its extreme price swings. This research was conducted to provide a framework for achieving optimal returns with minimal exposure to loss on the part of investors.
为了防止伪造,控制供应,并确保资产转移的合法性,电子货币使用了加密技术。主要关注的是比特币交易的盈利能力和波动性。投资的波动性可以通过计算对数收益的标准差来估计。本研究采用特异性检验来检验数据的正态性。图、统计过程控制图和其他分析的结果都指向显著的波动。越来越多的人重视不确定性。由于比特币价格的剧烈波动,投资者目前对其持谨慎态度。这项研究是为了提供一个框架,以实现最优的回报与最小的风险损失的部分投资者。

The environmental (climate change), economic (recessions), and social (increase in poverty and inequality) crises have forced the need for a change of model and the development of global strategies to counteract their negative effects and orient towards a type of economy that is low in carbon emissions, efficient in the use of resources and energy, socially inclusive, preventive in the loss of biodiversity and ecosystem services and that allows achieving sustainable development, which is how the concept of green economy arises. With a quantitative approach, using official databases and based on the Organization for Economic Co-operation and Development (2011) green growth framework, a Green Economic Growth Index for Mexico was constructed under the relativization function, which was estimated at the national, state, and geographic region levels, allowing for a deeper understanding of the green economy in the country. The results show an average national performance (0.4746), with the dimensions "Economic, demographic and social context for sustainable development," "Environmental dimension of quality of life," and "Natural asset base" having the best scores, while the dimension "Productivity of environmental resources and the economy" and "Economic opportunities and policy response" have the lowest scores. The analysis of variance results shows statistically significant differences by geographic regions, which calls for developing public, environmental, energy, and productive policies that consider the particular conditions of the country's regions.
环境(气候变化)、经济(衰退)和社会(贫困和不平等加剧)危机迫使我们必须改变模式和制定全球战略,以抵消它们的负面影响,并朝着低碳排放、有效利用资源和能源、具有社会包容性、预防生物多样性和生态系统服务丧失并能够实现可持续发展的经济类型发展。这就是绿色经济概念的由来。采用定量方法,利用官方数据库,基于经济合作与发展组织(2011)绿色增长框架,在相对化函数下构建了墨西哥绿色经济增长指数,并在国家、州和地理区域层面进行了估计,从而对该国的绿色经济有了更深入的了解。结果显示,全国平均表现为0.4746,其中“可持续发展的经济、人口和社会背景”维度、“生活质量的环境维度”和“自然资产基础”维度得分最高,而“环境资源和经济生产力”维度和“经济机会和政策响应”维度得分最低。对方差结果的分析显示,地理区域之间存在统计学上的显著差异,这就要求制定考虑到该国各地区特殊情况的公共、环境、能源和生产政策。

This paper examines the relationship between employee effort and earnings management. Data on working hours and discretionary cumulations of 29 non-financial companies listed in Tunisia are used. With an increased activity of employees, we find less profit management in Tunisian companies. This result evolves more critical when incomes are more predictable and persist after controlling for delayed endogeneity. However, we also find that increasing employee effort increases the likelihood of positive gains being realized for non-financial businesses. Our findings have important implications for investors and regulators looking to restrict earnings management.
本文研究了员工努力与盈余管理之间的关系。本文使用了29家在突尼斯上市的非金融公司的工作时间和可自由支配累积数据。随着员工活动的增加,我们发现突尼斯公司的利润管理减少了。当收入更具可预测性并在控制延迟内生性后持续存在时,这一结果变得更加重要。然而,我们也发现,增加员工的努力增加了非金融业务实现正收益的可能性。我们的研究结果对希望限制盈余管理的投资者和监管机构具有重要意义。

The significance of agricultural crops to an economy and their structural stability are shown by the production, area, and yield of agricultural output from commercial crops as well as by growth trends and structural stability. This study's objective is to evaluate the development, trend, and structural stability of commercial crop output in India before and after the implementation of the new agricultural policy from 1980 to 2000 and 2001 to 2020. To achieve the goals, secondary data will be used from the Reserve Bank of India's handbook of statistics on the Indian economy (2020–2021). Estimation methods included the least squares method, the t test, and the structural stability regression model. From 1980 to 2000, the average growth rate of commercial crops like Oilseeds, coffee, cotton, raw jute and mesta, sugarcane, tea, and tobacco were 59.1%, 66%, 159%, 21%, 4.4%, 52.2%, and 20.4 percent, respectively. The area under cultivation increased by13.4%, 69.6%, 33.3%, -17%, 31.9%, 33.3%, and -2.4 percent. In the pooled era, these commercial crops' production and area had correlation coefficients of 0.89, 0.93, -0.04, 0.02, 0.93, and 0.63, respectively. The study also shows that there is no significant difference in the variances of production and the yield of oilseeds and significant the area under cultivation. The yield and production of commercial crops are rising, while India's commercial production area and structure have altered over time. The emphasis should be on improving policy implementation and increasing yield through technological innovation, improved cultivation and area, agricultural research and development, and training in India.
农作物对经济的重要性及其结构稳定性体现在经济作物的产量、面积和产量以及增长趋势和结构稳定性上。本研究的目的是评估1980 - 2000年和2001 - 2020年新农业政策实施前后印度经济作物产量的发展、趋势和结构稳定性。为了实现这些目标,二级数据将来自印度储备银行的印度经济统计手册(2020-2021)。估计方法包括最小二乘法、t检验和结构稳定性回归模型。从1980年到2000年,油籽、咖啡、棉花、原黄麻和玉米、甘蔗、茶叶和烟草等经济作物的平均增长率分别为59.1%、66%、159%、21%、4.4%、52.2%和20.4%。耕地面积分别增长13.4%、69.6%、33.3%、-17%、31.9%、33.3%、- 2.4%。在混合时代,这些经济作物的产量和面积的相关系数分别为0.89、0.93、-0.04、0.02、0.93和0.63。研究还表明,油籽产量和产量差异不显著,种植面积差异显著。经济作物的产量和产量正在上升,而印度的商业生产面积和结构随着时间的推移发生了变化。重点应该放在通过技术创新、改良种植和面积、农业研究和发展以及印度的培训来改善政策实施和提高产量上。

The realistic problem of the continuous downturn of Chinese residents' consumption has a long history. The tsunami like covid-19 has further worsened the consumption situation of the Chinese people. Using the questions and contents of the "Japan Household Panel Survey" (JHPS) questionnaire of Keio University, and taking the employment rate of other married women with the same income level in the same community as a tool variable, this paper empirically examines the impact of urban married women's employment on household consumption. The results show that the employment of married women in cities and towns significantly increases household consumption; Through the verification of the mechanism, it is found that the increase of total household income and the increase of marginal propensity to consume are important mechanisms for married women to obtain employment to promote urban household consumption, in which the increase of income plays a greater role in the improvement of low-income household consumption, and the increase of marginal propensity to consume plays a greater role in the improvement of high-income household consumption; The employment of married women has a positive impact on all kinds of household consumption, but it plays a greater role in promoting developmental consumption.
我国居民消费持续低迷的现实问题由来已久。像新冠肺炎这样的海啸,进一步恶化了中国人民的消费状况。本文利用庆应义塾大学“日本家庭面板调查”(JHPS)问卷的问题和内容,以同一社区内其他收入水平相同的已婚妇女就业率为工具变量,实证检验了城市已婚妇女就业对家庭消费的影响。结果表明:城镇已婚妇女就业显著增加了家庭消费;通过对机制的验证,发现家庭总收入的增加和边际消费倾向的增加是已婚妇女就业促进城镇家庭消费的重要机制,其中收入的增加对低收入家庭消费的改善作用更大,边际消费倾向的增加对高收入家庭消费的改善作用更大;已婚妇女就业对家庭各类消费均有正向影响,但对发展性消费的促进作用更大。

Transportation has demonstrated its hegemonic position in the aftermath of the pandemic. In fact, despite the paralysis of many industries, transportation has continued its activity, demonstrating its value and resilience. As a result, it is one of the sectors with the more significant presence in global economies. Therefore, this research analyzes the thematic evolution of the relationship between transportation and the economy through scientific mapping and performance analysis. For this purpose, a study was carried out with all articles published on the Web of Science from 1900 to June 2022. The concurrence of authors, journals, research centers, keywords, documents, countries, and h-index was analyzed. SciMat and VOSviewer were used for insertion, de-duplication, normalization, categorization, analysis, interpretation, and graphical representation.The results have shown that, during periods of crisis such as the last pandemic, scientific production increases and the number of topics also doubles. However, sustainability, environment, and impact studies are the driving themes, so future lines of research may focus on different aspects or delve into relationships that do not only measure the economic and environmental impact of a transport infrastructure.
在大流行病之后,交通运输显示了其霸权地位。事实上,尽管许多行业陷入瘫痪,但交通运输仍在继续活跃,显示出其价值和弹性。因此,它是在全球经济中占有更重要地位的行业之一。因此,本研究通过科学的制图和绩效分析来分析交通与经济关系的主题演变。为此,对从1900年到2022年6月在科学网上发表的所有文章进行了一项研究。分析作者、期刊、研究中心、关键词、文献、国家、h指数的并发度。使用SciMat和VOSviewer进行插入、去重复、规范化、分类、分析、解释和图形表示。结果表明,在危机期间,如上次大流行期间,科学产出增加,主题数量也增加了一倍。然而,可持续性、环境和影响研究是驱动主题,因此未来的研究可能会关注不同的方面或深入研究不仅仅衡量交通基础设施的经济和环境影响的关系。

The present study is an attempt to provide new evidence on the long-run effects of global warming (via greenhouse gas emissions (GHG), carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), economic development (GDP growth rate), and forest area on the life expectancy by undertaking the annual time-series data of Pakistan during 1990 – 2016. The study employs the augmented Dickey-Fuller (ADF) test, Johansen co-integration, and Generalized Linear Model (GLM) to estimate the long-run effects, whereas, for robustness, this study employed the Least Squares Method (LSM) and Robust Least Squares Method (ROBUSTLS). In addition to this, the study undertakes the Granger causality test to predict the causality among the study variables. The outcomes of the GLM estimations provide the negative association of the total greenhouse gas emissions, carbon dioxide emissions, and forest area, and positive association of methane and nitrous oxide emissions with life expectancy. Further, Granger causality results provide the presence of bidirectional causality between carbon dioxide emissions and life expectancy and a unidirectional causality running from life expectancy to greenhouse gas emissions, methane emissions, and GDP. Based on the findings, the authors suggest controlling greenhouse gas emissions, including methane and nitrous oxide emissions, and focusing on the health sector to improve the life expectancy in Pakistan.
本研究试图通过对巴基斯坦1990 - 2016年的年度时间序列数据,为全球变暖(通过温室气体排放(GHG)、二氧化碳(CO2)、甲烷(CH4)和氧化亚氮(N2O)、经济发展(GDP增长率)和森林面积对预期寿命的长期影响提供新的证据。本研究采用增广Dickey-Fuller (ADF)检验、Johansen协整和广义线性模型(GLM)来估计长期效应,而在稳健性方面,本研究采用最小二乘法(LSM)和稳健最小二乘法(ROBUSTLS)。除此之外,本研究还进行了格兰杰因果检验来预测研究变量之间的因果关系。GLM估算的结果表明,温室气体排放总量、二氧化碳排放与森林面积呈负相关,而甲烷和一氧化二氮排放与预期寿命呈正相关。此外,格兰杰因果关系结果表明,二氧化碳排放与预期寿命之间存在双向因果关系,而预期寿命与温室气体排放、甲烷排放和GDP之间存在单向因果关系。基于这些发现,这组作者建议控制温室气体排放,包括甲烷和一氧化二氮的排放,并把重点放在卫生部门,以提高巴基斯坦人的预期寿命。

In addition to this, the study undertakes the Granger causality test to predict the causality among the study variables. The outcomes of the GLM estimations provide the negative association of the total greenhouse gas emissions, carbon dioxide emissions, and forest area, and positive association of methane and nitrous oxide emissions with life expectancy. Further, Granger causality results provide the presence of bidirectional causality between carbon dioxide emissions and life expectancy and a unidirectional causality running from life expectancy to greenhouse gas emissions, methane emissions, and GDP. Based on the findings, the authors suggest controlling greenhouse gas emissions, including methane and nitrous oxide emissions, and focusing on the health sector to improve the life expectancy in Pakistan.","PeriodicalId":210068,"journal":{"name":"Studies of Applied Economics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115287221","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}
