Abstract Research background Generally, corporate sustainability studies focus on identifying the relationship between corporate sustainability performance and corporate financial performance among different companies without measuring the company’s efficiency based on sustainability pillar scores. Purpose The essential aim of this paper is to explain the differentiation of business efficiency in terms of corporate sustainability performance by answering the question of how sustainability pillar scores influence the relative efficiency of a company? Research methodology The empirical studies were conducted among the 20 top companies listed on the WSE for the period of 2019–2021 with the use of the Data Envelopment Analysis (DEA) and the Spearman’s rank correlation coefficient. Results The research hypothesis, which states that more efficient companies are characterized by a higher level of sustainability in all its particular dimensions, cannot be positively verified, because a positive and statistically significant correlation dependence between the average efficiency measure and average sustainability pillar scores existed only for the governance dimension. Novelty The estimation of efficiency measure based on corporate sustainability performance has included not only environmental, social and governance dimensions, but also the economic one, which was represented by the long-term returns pillar score.
摘要研究背景一般来说,企业可持续发展研究的重点是识别不同公司之间的企业可持续发展绩效与企业财务绩效之间的关系,而不是基于可持续发展支柱得分来衡量公司的效率。本文的主要目的是通过回答可持续发展支柱得分如何影响公司的相对效率这一问题,来解释企业效率在企业可持续发展绩效方面的差异。研究方法采用数据包络分析(DEA)和Spearman等级相关系数,对2019-2021年在WSE上市的20家顶级公司进行实证研究。研究假设认为,效率更高的公司在所有特定维度上都具有更高的可持续性水平,但这一假设无法得到正性验证,因为平均效率测度与平均可持续性支柱得分之间仅在治理维度上存在正且统计显著的相关依赖关系。基于企业可持续发展绩效的效率测度评估不仅包括环境、社会和治理维度,还包括经济维度,以长期回报支柱得分为代表。

Abstract Research background In the past few years, MMT (Modern Money Theory or Modern Monetary Theory) has been increasingly discussed in Japan as well as in the U.S. However, both in the U.S. and Japan, analysis using mathematics is lacking and analysis using IS-LM and AD-AS analysis methods in macroeconomics is almost non-existent. Purpose We present an AD-AS analysis from the perspective of Functional Finance Theory and MMT (Modern Monetary Theory). Research methodology Graphical analyses with some mathematical analyses. Mathematical analyses include graphic analysis using AD and AS curves and calculations to derive equations representing them based on models of consumer and firm behavior. Results Using an overlapping generations model under monopolistic competition we show the following results by calculations and graphical analyses. 1. The budget deficit (including interest payments on government bonds) equals an increase in the savings of consumers from period to period. This result means that the debt-GDP ratio would not diverge to infinity, but would remain at a finite value whether the interest rate of government bonds is larger or smaller than the growth rate. 2. We need a budget deficit (including interest payments) to maintain full employment without inflation under economic growth. However, if the interest rate of government bonds is larger than the growth rate, we need a budget surplus (excluding interest payments) to maintain full employment without inflation. 3. A return to full employment from a recession can be achieved by implementing the appropriate fiscal policies through increased government spending or tax cuts. 4. Excessive government expenditure or an insufficient tax under full employment induces inflation. Novelty This is probably the first AD-AS analysis done from the standpoint of Functional Finance Theory and MMT.
摘要研究背景近年来,MMT (Modern Money Theory,现代货币理论)在日本和美国都得到了越来越多的讨论。然而,无论是在美国还是在日本,宏观经济学中都缺乏使用数学进行分析,几乎没有使用is - lm和AD-AS分析方法进行分析。目的从功能金融理论和现代货币理论的角度对AD-AS进行分析。研究方法:图形分析结合数学分析。数学分析包括使用AD和AS曲线的图形分析,以及根据消费者和企业行为模型推导出代表它们的方程的计算。结果利用垄断竞争条件下的代际重叠模型,通过计算和图形分析得到了以下结果。1. 预算赤字(包括政府债券的利息支付)等于每一时期消费者储蓄的增加。这一结果意味着,无论国债利率是大于还是小于增长率,债务与gdp之比都不会发散到无穷大,而是保持在一个有限值。2. 我们需要预算赤字(包括利息支付),以在经济增长的情况下维持充分就业,同时避免通胀。然而,如果国债利率高于增长率,我们需要预算盈余(不包括利息支付)来维持没有通胀的充分就业。3.通过实施适当的财政政策,增加政府支出或减税,可以从衰退中恢复到充分就业。4. 在充分就业的情况下,过度的政府开支或不足的税收会导致通货膨胀。这可能是第一次从功能金融理论和MMT的角度对AD-AS进行分析。

Solving Finite-Horizon Discounted Non-Stationary MDPS 求解有限视界折现非平稳MDPS
Pub Date : 2023-06-01 DOI: 10.2478/foli-2023-0001

Abstract Research background Markov Decision Processes (MDPs) are a powerful framework for modeling many real-world problems with finite-horizons that maximize the reward given a sequence of actions. Although many problems such as investment and financial market problems where the value of a reward decreases exponentially with time, require the introduction of interest rates. Purpose This study investigates non-stationary finite-horizon MDPs with a discount factor to account for fluctuations in rewards over time. Research methodology To consider the fluctuations of rewards with time, the authors define new nonstationary finite-horizon MDPs with a discount factor. First, the existence of an optimal policy for the proposed finite-horizon discounted MDPs is proven. Next, a new Discounted Backward Induction (DBI) algorithm is presented to find it. To enhance the value of their proposal, a financial model is used as an example of a finite-horizon discounted MDP and an adaptive DBI algorithm is used to solve it. Results The proposed method calculates the optimal values of the investment to maximize its expected total return with consideration of the time value of money. Novelty No existing studies have before examined dynamic finite-horizon problems that account for temporal fluctuations in rewards.
研究背景马尔可夫决策过程(mdp)是一个强大的框架,用于模拟许多具有有限视界的现实世界问题,这些问题在给定一系列行动的情况下最大化回报。尽管许多问题,如投资和金融市场问题,奖励的价值随着时间呈指数级下降,需要引入利率。目的:本研究探讨了非平稳的有限视界MDPs与贴现因子,以解释奖励随时间的波动。研究方法为了考虑报酬随时间的波动,作者定义了新的带折扣因子的非平稳有限视界mdp。首先,证明了有限视界折现mdp的最优策略的存在性。然后,提出了一种新的折扣逆向归纳(DBI)算法。为了提高建议的价值,本文以有限视界贴现MDP的财务模型为例,采用自适应DBI算法进行求解。结果该方法在考虑资金时间价值的情况下,计算出投资的最优值,使投资的预期总收益最大化。新颖性在此之前,还没有任何现有的研究考察了动态有限视界问题,该问题可以解释奖励的时间波动。

Abstract Research background Each type of administrative unit, including cities, towns and villages, plays a different role in the regional economy. In the case of rural areas, their most important function is agricultural production. Purpose This paper offers a contribution to the discussion on the review of the agricultural development strategy for Lubuskie Province. It attempts to present selected characteristics of the agricultural sector in a cross-section of municipalities of Lubuskie Province against the background of the general features of the agricultural sector in the region. Its purpose is to draw the attention of regional authorities and institutions to the heterogeneity of agricultural development within its territory. Research methodology The research was conducted using a principal component analysis as one of the methods of the graphical presentation of multivariate data. Data from the National Agricultural Census 2020 was used in the analysis. Results The results of the research corroborate the hypothesis of the existence of significant differences in the agricultural sector in the area of the examined rural and urban-rural municipalities in the region, and the need for differentiation of the measures used by the regional authorities to support agriculture in its territorial cross-section. Novelty The paper presents the results of a research on the heterogeneity of the development of the agricultural sector in the municipalities of the examined region. Such an analysis has never before been carried out for the province under consideration.
研究背景不同类型的行政单位,包括城市、乡镇和村庄,在区域经济中扮演着不同的角色。就农村地区而言,它们最重要的功能是农业生产。目的对卢布斯基省农业发展战略的回顾进行探讨。它试图在该地区农业部门的一般特点的背景下,在卢布斯基省各市的横截面上介绍农业部门的选定特点。其目的是提请区域当局和机构注意其领土内农业发展的异质性。研究方法本研究采用主成分分析作为多变量数据图形化呈现的方法之一。该分析使用了2020年全国农业普查的数据。研究结果证实了该地区农村和城乡自治市的农业部门存在显著差异的假设,以及区域当局在其领土横截面上支持农业的措施需要区分。本文提出了一项研究的结果,在研究区域的城市农业部门发展的异质性。以前从未对审议中的省进行过这样的分析。

Land Resources and Agricultural Exports Nexus 土地资源和农产品出口关系
Pub Date : 2023-06-01 DOI: 10.2478/foli-2023-0015

Abstract Research background As part of the process of structural transformation that countries go through in their development journey, the relative significance of agriculture as a sector typically shrinks over time. Nonetheless, the agricultural sector maintains its significance in terms of its trade potential and global employment prospects to this day. The extant literature largely neglects the impact of countries’ land resources on agricultural trade by emphasizing agricultural farm size and land productivity nexus. This justifies the exploration of the causal nexus between countries’ agricultural land resources and their agricultural exports. Purpose The study herein aims at investigating the nexus between countries’ total agricultural land resources and agricultural exports for 174 selected countries over the period 1991–2019. Research methodology Dumitrescu and Hurlin’s (2012) test for Granger non-causality for heterogeneous panels is harnessed. Results Estimation results evidence the presence of bi-directional causality (feedback) between countries’ agricultural land resources and agricultural exports not only in the whole panel (1991–2019) but also in subpanels too (1991–2000, 2001–2010, and 2011–2019). Overall, the results stress the strategic importance of agricultural land as a significant determinant of agricultural exports. Novelty Our study takes a unique approach and investigates if there is a cause-and-effect relationship between a country’s agricultural land resources and its agricultural exports by relying on the implications of the factor endowment theory of trade.
研究背景作为各国在发展过程中经历的结构转型过程的一部分,农业作为一个部门的相对重要性通常会随着时间的推移而缩小。尽管如此,农业部门至今在其贸易潜力和全球就业前景方面仍具有重要意义。现有文献通过强调农场规模和土地生产力的关系,在很大程度上忽略了国家土地资源对农业贸易的影响。这证明了探索各国农业用地资源与其农业出口之间的因果关系是合理的。本研究旨在调查1991-2019年174个国家的农业用地资源总量与农产品出口之间的关系。研究方法采用Dumitrescu和Hurlin(2012)对异质性面板的格兰杰非因果关系检验。估计结果表明,不仅在整个面板(1991-2019)中,而且在子面板(1991-2000、2001-2010和2011-2019)中,各国的农业用地资源与农业出口之间存在双向因果关系(反馈)。总体而言,研究结果强调了农业用地作为农业出口的重要决定因素的战略重要性。本文采用独特的研究方法,运用贸易要素禀赋理论考察一国的农地资源与其农产品出口之间是否存在因果关系。

An Evaluation of Circular Economy Development in the Baltic States 波罗的海国家循环经济发展评价
Pub Date : 2022-12-01 DOI: 10.2478/foli-2022-0026

Abstract Research background: The fact that all resources are not infinite and the needs of society are steadily increasing, new ways of producing, consuming and waste disposal should be adopted. A circular economy as a modern alternative to a linear economy became one of the priorities of the European Union in order to create a modern, resource-efficient and competitive system. Purpose: The purpose of this article is to present the concept of a circular economy and the justification of its implementation based on a literature review. The article focuses on determining the factors of a circular economy and evaluating its importance in the Baltic States. In other words, the main aim of the article is to highlight the factors of a circular economy and assess its significance. Research methodology: A panel regression analysis was used in order to evaluate which indicator of the selected circular economy factors is the most important. Results: The survey reveals that waste electrical and electronic equipment has the most significant potential for increased circular material use rate in the Baltic States. All electrical and electronic equipment should be designed so that it would be possible to repair and reuse it to extend the product life cycle and reduce the carbon footprint. Reducing greenhouse gas emissions in conjunction with increasing the usage of renewable energy could increase resource productivity and domestic material consumption (DMC) and ensure Baltic States’ independence in the energy sector through offshore wind farms that have the region’s most considerable potential. Novelty: There is a lack of studies conducted in the Baltic States focused on circular economy development using panel data. Most of the previous studies were focused on the European Union as a whole or individual countries. This study presents a deeper analysis of circular economy development in the Baltic States.
摘要研究背景:在资源不是无限的,社会需求在不断增长的情况下,应采用新的生产、消费和废物处理方式。循环经济作为线性经济的现代替代品成为欧盟的优先事项之一,以创建一个现代的、资源高效的和有竞争力的体系。目的:本文的目的是在文献综述的基础上提出循环经济的概念及其实施的理由。本文的重点是确定循环经济的因素,并评估其在波罗的海国家的重要性。换句话说,本文的主要目的是突出循环经济的因素并评估其重要性。研究方法:采用面板回归分析的方法来评价所选循环经济因素中哪个指标最重要。结果:调查显示,在波罗的海国家,废旧电器和电子设备在提高循环材料使用率方面具有最大的潜力。所有电气和电子设备的设计都应使其能够维修和再利用,以延长产品生命周期并减少碳足迹。减少温室气体排放,同时增加可再生能源的使用,可以提高资源生产率和国内材料消耗(DMC),并通过该地区最具潜力的海上风电场确保波罗的海国家在能源部门的独立性。新颖性:波罗的海国家缺乏利用面板数据对循环经济发展进行的研究。以前的研究大多集中在整个欧盟或个别国家。本研究对波罗的海国家循环经济的发展进行了更深入的分析。

The article focuses on determining the factors of a circular economy and evaluating its importance in the Baltic States. In other words, the main aim of the article is to highlight the factors of a circular economy and assess its significance. Research methodology: A panel regression analysis was used in order to evaluate which indicator of the selected circular economy factors is the most important. Results: The survey reveals that waste electrical and electronic equipment has the most significant potential for increased circular material use rate in the Baltic States. All electrical and electronic equipment should be designed so that it would be possible to repair and reuse it to extend the product life cycle and reduce the carbon footprint. Reducing greenhouse gas emissions in conjunction with increasing the usage of renewable energy could increase resource productivity and domestic material consumption (DMC) and ensure Baltic States’ independence in the energy sector through offshore wind farms that have the region’s most considerable potential. Novelty: There is a lack of studies conducted in the Baltic States focused on circular economy development using panel data. Most of the previous studies were focused on the European Union as a whole or individual countries. This study presents a deeper analysis of circular economy development in the Baltic States.","PeriodicalId":314664,"journal":{"name":"Folia Oeconomica Stetinensia","volume":"286 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115604138","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}

Abstract Research background: Active labour market policy measures serve to improve the situation with unemployment and the placeability of jobseekers in the labour market. An important tool for the functioning of these interventions is their continuous monitoring and evaluation. Purpose: In this paper, we focus on the Allowance for self-employment gainful activity aimed at providing the financial contribution to start a business. The paper aims to find out those jobseekers’ characteristics that mostly increase the probability of participation in this intervention. Research methodology: We use data from the database of jobseekers of the Central Office of Labour, Social Affairs and Family in Slovakia, the probability model is constructed by a logistic regression. Results: We found several characteristics that significantly impact the decision to participate in the measure. Jobseekers with previous employment in service activities (NACE S), married, long-term unemployed and with a 2nd university degree have a higher chance of participating in this program of the labour market. On the contrary, high age, low education or permanent residence in the Bratislava region decreases the chance for participation in this intervention. Novelty: Knowing the individuals’ characteristics that significantly contribute to the interest in participating in this program can help policymakers set the instrument’s eligibility conditions and allocate funds to increase interest in using this treatment where necessary.
摘要研究背景:积极的劳动力市场政策措施有助于改善失业状况和求职者在劳动力市场的可安置性。这些干预措施发挥作用的一个重要工具是对其进行持续监测和评价。目的:在本文中,我们关注的是旨在为创业提供财政贡献的自营职业有酬活动津贴。本文的目的是找出那些求职者的特征,大多增加了参与这种干预的可能性。研究方法:我们使用斯洛伐克中央劳动、社会事务和家庭办公室求职者数据库中的数据,通过逻辑回归构建概率模型。结果:我们发现了几个显著影响参与测量的决定的特征。有服务行业工作经验(NACE S)、已婚、长期失业和拥有第二大学学位的求职者有更高的机会参加劳动力市场的这个项目。相反,在布拉迪斯拉发地区,年龄大、受教育程度低或永久居住减少了参与这种干预的机会。新颖性:了解对参与该计划有重大影响的个人特征,可以帮助政策制定者设定该工具的资格条件,并分配资金,以在必要时增加使用该治疗的兴趣。

Abstract Research background: In recent decades, scientists have focused on sustainable development goals. Cultural issues are evident in sustainable development, but the scientific inclusion of cultural aspects remains a challenge. Purpose: The study aims to link cultural aspects and sustainability goals. Also, the purpose of this study, is to use the composite cultural index to include the latest research findings on this matter and extend them to cover the six cultural dimensions identified in the Hofstede cultural model. Yeganeh (2011) proposed a methodology for compiling a composite cultural index, but the author included only a few cultural dimensions. The authors of this article present an analysis of fifteen Sustainable Development Goals in the 27 countries of the European Union to rank countries according to the contribution of national culture to the Sustainable Development Goals. Research methodology: The methodology used an international expert survey on the dimensions of culture and the constructed correlation matrix. Results: The results show a correlation between the four goals of sustainable development, although the direction is different: one has a positive relationship, and three have a negative one. Novelty: The article’s value is that the authors created a composite cultural index for research on sustainable development and expanded the results presented by other authors.
摘要研究背景:近几十年来,可持续发展目标成为科学家关注的焦点。文化问题在可持续发展中是显而易见的,但科学地纳入文化方面仍然是一个挑战。目的:本研究旨在将文化方面与可持续发展目标联系起来。此外,本研究的目的,是使用复合文化指数,包括在这个问题上的最新研究成果,并扩展到涵盖Hofstede文化模型中确定的六个文化维度。Yeganeh(2011)提出了一种编制复合文化指数的方法,但作者只包括了几个文化维度。本文作者对欧盟27个国家的15个可持续发展目标进行了分析,并根据国家文化对可持续发展目标的贡献对各国进行了排名。研究方法:研究方法采用国际专家对文化维度的调查和构建的相关矩阵。结果:4个可持续发展目标之间存在相关性,但方向不同,1个为正相关,3个为负相关。新颖性:本文的价值在于为可持续发展研究创造了一个综合文化指数,拓展了前人的研究成果。

Abstract Research background: The aim of the article is to compare Polish and US dividend companies with potential growth with dividend companies with potential value, including in the period of economic turbulence caused by the pandemic, and to identify macroeconomic determinants that affect changes in the level of share prices of dividend companies with potential value listed on the stock exchange in Poland and the US. An analysis of the literature and international studies conducted allows us to identify inflation, gross domestic product (GDP), interest rate levels, exchange rate changes, and market P/E and P/BV ratios, as well as the PMI index, as the most important macroeconomic factors. Purpose: The aim of the article was to present research on the impact of macroeconomic indicators on the prices of Polish and US shares of dividend companies, divided into shares with potential value and potential growth for the period 2016–2020. The research was enriched by analyzing the return rate on shares and the risk of the share prices of companies with potential value during the turbulence of the economy caused by the COVID-19 pandemic. Research methodology: The study was conducted using the Spearman rank correlation coefficient and significance test for the Spearman rank correlation coefficient. A non-parametric t-test was carried out to check whether the estimated correlation is statistically significant. Results: The research indicates that Polish and US dividend companies with potential value have lower average annual return rates than dividend companies with potential growth. Referring to the determinants of the share prices of US dividend companies with potential value, it was found that they are significantly determined by inflation and moderately determined by industrial production and GDP, as well as the P/BV ratio. Novelty: The added and application value are the recommendations regarding the attractiveness of investing in Polish dividend companies with potential value as compared to companies from the US market.
摘要研究背景:本文的目的是比较波兰和美国具有潜在成长性的股息公司与具有潜在价值的股息公司,包括在疫情造成的经济动荡时期,并确定影响波兰和美国证券交易所上市的具有潜在价值的股息公司股价水平变化的宏观经济决定因素。通过对文献和国际研究的分析,我们可以确定通货膨胀、国内生产总值(GDP)、利率水平、汇率变化、市场市盈率和市盈率/账面价值比以及PMI指数是最重要的宏观经济因素。目的:本文的目的是研究宏观经济指标对波兰和美国股息公司股票价格的影响,这些股票分为2016-2020年期间具有潜在价值和潜在增长的股票。通过分析新冠肺炎疫情造成的经济动荡期间具有潜在价值的公司的股票收益率和股价风险,丰富了研究内容。研究方法:采用Spearman秩相关系数和Spearman秩相关系数显著性检验进行研究。采用非参数t检验来检验估计的相关性是否具有统计学意义。结果:研究表明,波兰和美国具有潜在价值的股息公司的平均年回报率低于具有潜在成长性的股息公司。参考具有潜在价值的美国股利公司股价的决定因素,发现通货膨胀对股价的决定作用显著,工业生产和GDP以及P/BV对股价的决定作用适度。新颖性:附加价值和应用价值是关于投资波兰股息公司与美国市场公司相比具有潜在价值的吸引力的建议。
