Abstract Mathematical models of economic dynamics and growth are usually expressed in terms of differential equations/inclusions (in the case of continuous time) or difference equations/inclusions (if discrete time is assumed).3 This class of models includes von Neumann-Leontief-Gale type dynamic input-output models to which the paper refers. The paper focuses on the turnpike stability of optimal growth processes in a Gale non-stationary economy with discrete time in the neighbourhood of von Neumann dynamic equilibrium states (so-called growth equilibrium). The paper refers to Panek (2019, 2020) and shows an intermediate result between the strong and very strong turnpike theorem in the non-stationary Gale economy with changing technology assuming that the prices of temporary equilibrium in such an economy (so-called von Neumann prices) do not change rapidly. The aim of the paper is to bring mathematical proof that the introduction of these assumptions making the model more realistic does not change its asymptotic (turnpike-like) properties.
经济动态和增长的数学模型通常用微分方程/包含(在连续时间的情况下)或差分方程/包含(如果假设是离散时间)来表示这类模型包括本文引用的von Neumann-Leontief-Gale型动态输入输出模型。本文研究了具有离散时间的大风非平稳经济中最优增长过程在冯诺依曼动态平衡状态(即增长平衡)附近的收费公路稳定性问题。本文引用Panek(2019,2020),并展示了在技术变化的非平稳Gale经济中强收费公路定理和非常强收费公路定理之间的中间结果,假设这种经济中的临时均衡价格(所谓的冯·诺伊曼价格)不会迅速变化。本文的目的是提供数学证明,证明这些假设的引入使模型更现实,但不会改变其渐近(类似收费公路)的性质。

“Poverty has no causes, wealth has causes”—this statement, attributed to the development economist Peter Bauer (1915-2002),1 may serve as the title of a book on the entire history of growth theory since Adam Smith’s An inquiry into the nature and causes of the wealth of nations (Smith, 1776). Indeed to understand why the standard of living differs across people, countries and time we need to understand the causes of wealth. This is the topic of the current Economics and Business Review. With this issue the Review honours the outstanding contribution of Professor Oded Galor, Herbert H. Goldberger Professor of Economics at Brown University, to the field of growth theory. At the same time it celebrates the degree of doctor honoris causa that the Poznań University of Economics and Business conferred on him in 2019.2 Oded Galor’s eminent research on the causes and the consequences of economic growth has substantially advanced our understanding of how and why economies accumulate wealth differently. His research has a tremendous impact on the scientific community. The breadth as well as the depth of his research agenda is impressive.3 Seminal contributions to the fields of inequality and economic growth (Galor & Zeira, 1993) and of comparative development (Ashraf & Galor, 2011) stand out. Research papers like Galor and Moav (2002) and Ashraf and Galor (2013) initiated a new literature on the deep roots in comparative economic development. In the profession and beyond, Oded Galor is probably best known as the founder of Unified Growth Theory (Galor, 2005, 2011). This fascinating theory depicts humanity’s process of economic development from the Malthusian Regime to the Modern Growth Regime in a single analytical framework that accounts for the specifics of each regime as well as for the endogenous transition between them. The first paper of this issue is Oded Galor’s article The journey of humanity: Roots of inequality in the wealth of nations. Here the author provides a brief and concise world economic history from the vantage point of Unified Growth Theory.

“贫穷没有原因,财富有原因”——这句出自发展经济学家彼得·鲍尔(1915-2002)的话,可以作为自亚当·斯密的《国家财富的性质和原因的探究》(史密斯,1776)以来关于整个增长理论历史的一本书的标题。的确,要理解为什么不同的人、不同的国家和不同的时代的生活水平不同,我们需要了解财富的成因。这是本期《经济与商业评论》的主题。本期《经济评论》向布朗大学(Brown University)赫伯特·h·戈德伯格(Herbert H. Goldberger)经济学教授奥德·加罗尔(Oded Galor)教授在增长理论领域做出的杰出贡献表示敬意。与此同时,它庆祝波兹纳瓦经济与商业大学于2019年授予他荣誉博士学位。奥德·加洛尔在经济增长的原因和后果方面的杰出研究,大大提高了我们对经济如何以及为何以不同方式积累财富的理解。他的研究对科学界产生了巨大的影响。他研究议程的广度和深度都令人印象深刻在不平等和经济增长(Galor & Zeira, 1993)和比较发展(Ashraf & Galor, 2011)领域的开创性贡献脱颖而出。Galor and Moav(2002)和Ashraf and Galor(2013)等研究论文开创了关于比较经济发展深层根源的新文献。在这个行业内外,Oded Galor可能是最著名的统一增长理论的创始人(Galor, 2005,2011)。这个引人入胜的理论描述了人类经济发展的过程,从马尔萨斯制度到现代增长制度,在一个单一的分析框架,说明了每个制度的特点,以及它们之间的内生过渡。本期的第一篇论文是奥德·加洛的文章《人类之旅:国家财富不平等的根源》。在这里,作者从统一增长理论的角度提供了一个简短而简洁的世界经济史。从智人出现到现在的30万年时间跨度,他的重点是人类历史上两个惊人的谜团,即:1)在大部分地区出现持续的经济增长

Abstract The aim of this paper is to examine a complex pattern of mutual interdependence between Unified Growth Theory (subroutine) and the evolution of the entire field of economic growth theories (main routine) from a philosophical and methodological perspective. The analysis utilises the recently introduced concept of research routine (and respectively, subroutine) aimed at an explanation of the evolution of scientific research. The study identifies the influence of the subroutine (and its specific concept of demographic transition) on the core concepts of the main routine: human capital, population growth and learning. The results are based on network analyses of extensive bibliometric evidence from Scopus and the Web of Knowledge.
摘要本文旨在从哲学和方法论的角度审视统一增长理论(子程序)与整个经济增长理论领域(主程序)的演变之间相互依存的复杂模式。分析利用了最近引入的研究例程(以及相应的子例程)的概念,旨在解释科学研究的演变。该研究确定了子程序(及其人口转型的具体概念)对主程序的核心概念:人力资本、人口增长和学习的影响。这些结果是基于对来自Scopus和Web of Knowledge的大量文献计量证据的网络分析。

Abstract The Israeli economy in the first two decades of the 21st century is an example of an economic transformation that may serve as a role model for addressing many challenges to economic growth. Data from this period have shown significant developments in economic growth over this relatively short period of time and indicate that these advances are attributable to policies targeting inflation, labor force participation and education. While challenges remain—including economic inequality, suboptimal health care and the threat of coronavirus pandemic to global growth—we explore developments evidenced to promote economic growth.
21世纪头二十年的以色列经济是经济转型的一个例子,可以作为解决经济增长面临的许多挑战的榜样。这一时期的数据表明,在这段相对较短的时间内,经济增长取得了重大进展,并表明这些进展可归因于针对通货膨胀、劳动力参与和教育的政策。尽管挑战依然存在,包括经济不平等、不理想的医疗保健以及冠状病毒大流行对全球增长的威胁,但我们将探讨促进经济增长的证据。

Determinants of the non-performing loan ratio in the European Union banking sectors with a high level of impaired loans 不良贷款率的决定因素是欧盟银行部门的不良贷款水平较高

Abstract In the article an attempt is made to identify the quality of credit exposure determinants of banks in European Union countries that were characterized by a high level of impaired loans at the end of 2017 (Bulgaria, Croatia, Cyprus, Italy, Ireland, Greece, Portugal). Using the static panel-based approach the non-performing loan (NPL) determinants for the period from 2011 to 2017 were analyzed. The results showed that the high level of NPLs can be explained mainly by both macroeconomic and microeconomic factors. In particular, it has been shown that in the surveyed countries supervisory authorities should pay special attention to smaller banks with high dynamics of new loans and a low return on assets due to the fact that these entities are characterized by a higher NPL ratio. A higher level of NPL is also affected by a high concentration of the banking sector and higher interest rates on newly granted loans. As a result of research it was also shown that the majority of NPL determinants are the same in all types of banks, regardless of the business model and the scope of banking supervision. The differences were noticeable in characteristics regarding the housing market as well as the profitability of operations and lending dynamics of the analyzed entities.
摘要本文试图确定2017年底欧盟国家(保加利亚、克罗地亚、塞浦路斯、意大利、爱尔兰、希腊、葡萄牙)银行的信贷风险敞口决定因素的质量,这些国家的特点是减值贷款水平很高。使用基于静态面板的方法分析了2011年至2017年期间的不良贷款(NPL)决定因素。结果表明,我国银行业不良贷款水平高的主要原因是宏观经济因素和微观经济因素。特别是,调查显示,在被调查的国家,监管当局应特别关注新贷款动态高、资产回报率低的小型银行,因为这些实体的特点是不良贷款率较高。不良贷款率较高还受到银行业高度集中和新发放贷款利率较高的影响。研究结果还表明,无论商业模式和银行监管范围如何,大多数不良贷款决定因素在所有类型的银行中都是相同的。这些差异在住房市场特征以及被分析实体的业务盈利能力和贷款动态方面是明显的。

Abstract The aim of this paper is to bring together some of the foundational and recent literature interlinking corporate governance and the leadership role of the board of directors. Strategic leadership is widely assumed to be a responsibility that defaults to the Chief Executive Officers (CEOs). However, in practice, what most CEOs do is strategic management rather than strategic leadership. While strategic management does share key aspects of strategic leadership CEOs are expected to prioritize the managerial side over the leadership side. This is just one of the situations in which the board-room assumes the leadership role. This paper discusses how boards of directors conduct the process of strategic leadership in their organizations. In recent years there has been an increasing interest among scholars to understand how boards strategize from a behavioral point of view. This growing interest has resulted in the development of various typologies regarding boards’ involvement in the strategic leadership processes.
摘要本文的目的是汇集一些基础和最近的文献相互关联的公司治理和董事会的领导作用。战略领导被广泛认为是首席执行官(ceo)的责任。然而,在实践中,大多数ceo所做的是战略管理,而不是战略领导。虽然战略管理确实分享了战略领导的关键方面,但ceo们应该优先考虑管理方面,而不是领导方面。这只是董事会承担领导角色的情况之一。本文讨论了董事会如何在其组织中进行战略领导的过程。近年来,学者们越来越有兴趣从行为的角度来理解董事会如何制定战略。这种日益增长的兴趣导致了关于董事会参与战略领导过程的各种类型的发展。

Abstract The main goal of this research is to analyse the investment benefits from an incorporation of the volatility exposure to the diversified portfolio from the perspective of a Polish investor. Volatility, treated as a new asset class, may improve the performance of the portfolio due to its negative correlation with most types of assets. This topic has been widely investigated for the United States and Europe whereas the Polish market appears to be not heavily researched and this study may fill this gap. The research covers the period from October 2010 to July 2018 and is performed on daily close prices. To construct the portfolios the analysis uses the mean-variance framework and the naïve diversification approach. The comparison of risk-adjusted returns between investments with and without volatility exposure enables an answer to the research question about an improvement of the results by the addition of a non-standard asset to the diversified portfolios. The VXX is considered as the proxy for volatility as it is the most popular ETN which follows the volatility index derivatives with the given maturity. To test the robustness of the results the portfolios are constructed with a broad range of different parameters and assumptions imposed on the optimization procedure.
摘要:本研究的主要目的是从波兰投资者的角度分析波动性暴露于多元化投资组合的投资收益。波动率作为一种新的资产类别,由于其与大多数资产类型的负相关,可能会改善投资组合的绩效。这个话题已经在美国和欧洲进行了广泛的调查,而波兰市场似乎没有进行大量的研究,这项研究可能会填补这一空白。该研究涵盖2010年10月至2018年7月期间,并以每日收盘价为基准。为了构建投资组合,分析使用均值-方差框架和naïve多样化方法。对有和没有波动风险敞口的投资之间的风险调整收益进行比较,可以回答研究问题,即通过在多元化投资组合中添加非标准资产来改善结果。VXX被认为是波动性的代表,因为它是最受欢迎的ETN,它遵循给定期限的波动性指数衍生品。为了检验结果的稳健性,在优化过程中使用了广泛的不同参数和假设来构建组合。

Abstract Following Chilean experiences as well as the World Bank suggestions post-communist Poland and post-collectivist Israel—underwent deep reforms which led to the privatization of old age security. The aim of the article is to compare the Polish and Israeli paths of pension privatization in the last thirty years. The main conclusions are: (1) the economic, demographic and political environments at the moment of the design and implementation of the pension reform were quite similar in both countries; however (2) the scope and scale of the privatization was different: in Poland there was only partial shift towards private pension system while in Israel full privatization of the system was implemented; (3) the decisive factors were: the inertia of the already existing pension systems and the power of foreign influencers; (4) the retreat from privatization in Poland and the increase in Israel took place due to the different mix of disadvantages of the new pension arrangements, short-term political aims and international pressure.
继智利的经验以及世界银行的建议之后,后共产主义的波兰和后集体主义的以色列进行了深刻的改革,导致了老年保障的私有化。本文的目的是比较波兰和以色列在过去三十年的养老金私有化道路。主要结论有:(1)两国在设计和实施养老金改革时的经济、人口和政治环境非常相似;然而(2)私有化的范围和规模是不同的:在波兰,只有部分转向私人养恤金制度,而在以色列,该制度完全私有化;(3)决定性因素是:现有养老金制度的惯性和外国影响者的力量;(4)波兰私有化的退却和以色列私有化的增加是由于新的养老金安排的不利因素、短期政治目标和国际压力的不同组合造成的。

Abstract With the increase in global spatial mobility the importance of migration policy (including integration policy) is increasing day by day, both in developed countries and new market economies. In the course of the research on migration policy various measures were constructed. Even though the particular measures relate to different areas of migration policy, they do not refer to the effectiveness of migration policy. The aim of this study is to assess the effectiveness of the integration of immigrants into the labour market in the countries that belong to the Organisation for Economic Co-Operation and Development (OECD) and to analyse the relationships between these effects and the integration policy adopted by the individual countries. The TOPSIS (Technique for Order Preference by Similarity to an Ideal Solution) method and the CRITIC (Criteria Importance Through Intercriteria Correlation) method were used in the research. The results indicate that the highest effectiveness of migration policy in terms of integration of immigrants into the labour market was reported in the following OECD countries: Iceland, Switzerland and New Zealand. The results also suggest that the higher the level of integration policy restrictiveness in a given country, the worse the effects in terms of integration of immigrants into the labour market that were noticed by this country.
随着全球空间流动性的增加,移民政策(包括一体化政策)的重要性日益增加,无论是在发达国家还是新兴市场经济体。在研究移民政策的过程中,构建了多种移民政策措施。尽管这些具体措施涉及移徙政策的不同领域,但它们并不涉及移徙政策的有效性。本研究的目的是评估经济合作与发展组织(经合组织)成员国移民融入劳动力市场的有效性,并分析这些影响与各个国家采取的融入政策之间的关系。研究中采用了TOPSIS(通过与理想解相似度来排序偏好的技术)方法和CRITIC(通过标准间相关性来判断标准重要性)方法。结果表明,据报告,移民政策在使移民融入劳动力市场方面最有效的是下列经合发组织国家:冰岛、瑞士和新西兰。研究结果还表明,一个特定国家的融合政策限制水平越高,该国注意到的移民融入劳动力市场的影响就越差。

An analysis of the logistics performance index of EU countries with an integrated MCDM model 基于集成MCDM模型的欧盟国家物流绩效指标分析

Abstract Countries can check the performance of their logistics’ activities to determine their competitiveness in trade logistics. One way to check these performances is to analyze the country’s LPI value in detail which is released by the WB every two years. When calculating the LPI, six indicators (criteria) are taken into account. The weights (importance level) of these criteria are important for countries which would like to focus more on the most important criteria and move their ranking up in the LPI list. However the WB takes into account indicators (criteria) weights equally when calculating LPI values. In order to overcome this problem some studies have used subjective weighting methods and others have used objective weighting methods. Both methods have advantages and disadvantages. The aim of this study is to integrate two weighting methods (subjective (SWARA) and objective (CRITIC)) in determining the weights of criteria in order to balance the two weighting methods. Unlike other studies in the literature this study combines two weighting methods. Additionally the PIV method, which is seldom used to address any MCDM problem, is used in this study and a new integrated MCDM model is introduced to literature. In this respect this study contributes to the literature.
各国可以通过检查其物流活动的绩效来确定其在贸易物流中的竞争力。检查这些表现的一种方法是详细分析世界银行每两年发布一次的该国的LPI值。在计算LPI时,要考虑六个指标(标准)。这些标准的权重(重要性水平)对于那些希望更多地关注最重要标准并提高其在LPI列表中的排名的国家来说很重要。然而,在计算LPI值时,WB平等地考虑了指标(标准)权重。为了克服这一问题,有的研究采用主观加权法,有的研究采用客观加权法。两种方法各有优缺点。本研究的目的是整合两种加权方法(主观(SWARA)和客观(CRITIC))来确定标准的权重,以平衡两种加权方法。与文献中的其他研究不同,本研究结合了两种加权方法。此外,本研究还采用了以往很少用于解决MCDM问题的PIV方法,并引入了一种新的集成MCDM模型。在这方面,本研究对文献有所贡献。
