A significant number of the non-financial firms listed at Nairobi Securities Exchange (NSE) have been experiencing declining financial performance which deter investors from investing in such firms. The lenders are also not willing to lend to such firms. As such, the firms struggle to raise funds for their operations. Prudent financing decisions can lead to financial growth of the firm. The purpose of this study is to assess the effect of Long-term debt on the financial growth of Non-financial firms listed at Nairobi Securities Exchange. Financial firms were excluded because of their specific sector characteristics and stringent regulatory framework. The study is guided by Trade-Off Theory and Theory of Growth of the Firm. Explanatory research design was adopted. The population of the study comprised of 45 non-financial firms listed at the NSE for a period of ten years from 2008 to 2017. The study conducted both descriptive statistics analysis and panel data analysis. The result indicates that Long term debt explains 21.6% and 5.16% of variation in financial growth as measured by growth in earnings per share and growth in market capitalization respectively. Long term debt positively and significantly influences financial growth measured using both growth in earnings per share and growth in market capitalization. The study recommends that, the management of non-financial firms listed at Nairobi Securities Exchange to employ financing means that can improve the earnings per share, market capitalization and enhance the value of the firm for the benefit of its stakeholders.
在内罗毕证券交易所(NSE)上市的大量非金融公司的财务业绩一直在下降,这使投资者不敢投资这些公司。银行也不愿意贷款给这些公司。正因如此,这些公司难以筹集运营资金。审慎的融资决策可以导致公司的财务增长。本研究的目的是评估长期债务对在内罗毕证券交易所上市的非金融公司财务增长的影响。金融公司因其特定的行业特征和严格的监管框架而被排除在外。本研究以权衡理论和企业成长理论为指导。采用解释研究设计。该研究的人口包括45家在NSE上市的非金融公司,时间为2008年至2017年的10年。本研究采用描述性统计分析和面板数据分析。结果表明,长期债务分别解释了每股收益增长和市值增长的21.6%和5.16%的财务增长变化。长期债务对财务增长产生积极而显著的影响,财务增长采用每股收益增长和市值增长来衡量。本研究建议,在内罗毕证券交易所上市的非金融公司的管理层采用融资手段,可以提高每股收益、市值和提高公司的价值,使其利益相关者受益。

Obamacare and a Fix for the IRS Iteration 奥巴马医改和对国税局反复的修正
Pub Date : 2020-08-07 DOI: 10.1090/noti2320
Samuel J. Ferguson
We model the quantities appearing in Internal Revenue Service (IRS) tax guidance for calculating the health insurance premium tax credit created by the Patient Protection and Affordable Care Act, also called Obamacare. We ask the question of whether there is a procedure, computable by hand, which can calculate the appropriate premium tax credit for any household with self-employment income. We motivate current IRS tax guidance, which has had self-employed taxpayers use a fixed point iteration to calculate their premium tax credits since 2014. Then, we give an example showing that the IRS iteration can lead to a divergent sequence of iterates. As a consequence, IRS guidance does not calculate appropriate premium tax credits for tax returns in certain income intervals, adversely affecting eligible beneficiaries. A bisection procedure for calculating premium tax credits is proposed. We prove that this procedure calculates appropriate premium tax credits for a model of simple tax returns. This is generalized to the case where premium tax credits are received in advance, which is the most common one in applications. We outline the problem of calculating appropriate premium tax credits for models of general tax returns. While the bisection procedure will work with the tax code in its current configuration, it could fail, eg, in states which have not expanded Medicaid, if a new deduction with certain properties were to arise.
我们对美国国税局(IRS)税收指南中出现的数量进行建模,以计算由《患者保护和平价医疗法案》(也称为奥巴马医改)创建的医疗保险费税收抵免。我们要问的问题是,是否有一种可以手工计算的程序,可以为任何有自营职业收入的家庭计算适当的保费税收抵免。我们鼓励现行的国税局税务指导,自2014年以来,自雇纳税人使用定点迭代来计算他们的保费税收抵免。然后,我们给出了一个例子,表明IRS迭代可以导致迭代的发散序列。因此,美国国税局的指导方针没有计算特定收入区间纳税申报表的适当保费税收抵免,对符合条件的受益人产生不利影响。提出了一种计算保费税收抵免的二分法。我们证明了这个程序计算适当的保费税收抵免的简单纳税申报模型。这可以推广到提前收到保费税收抵免的情况,这是申请中最常见的情况。我们概述了计算一般纳税申报表模型的适当保费税收抵免的问题。虽然二分法在目前的配置下适用于税法,但如果出现带有某些属性的新扣除额,它可能会失效,例如,在没有扩大医疗补助的州。

Global supply networks in agriculture, manufacturing, and services are a defining feature of the modern world. The efficiency and the distribution of surpluses across different parts of these networks depend on choices of intermediaries. This paper conducts price formation experiments with human subjects located in large complex networks to develop a better understanding of the principles governing behavior. Our first finding is that prices are larger and that trade is significantly less efficient in small-world networks as compared to random networks. Our second finding is that location within a network is not an important determinant of pricing. An examination of the price dynamics suggests that traders on cheapest -- and hence active -- paths raise prices while those off these paths lower them. We construct an agent-based model (ABM) that embodies this rule of thumb. Simulations of this ABM yield macroscopic patterns consistent with the experimental findings. Finally, we extrapolate the ABM on to significantly larger random and small world networks and find that network topology remains a key determinant of pricing and efficiency.
农业、制造业和服务业的全球供应网络是现代世界的一个显著特征。这些网络不同部分的效率和剩余分配取决于中介机构的选择。本文对处于大型复杂网络中的人类受试者进行了价格形成实验,以更好地理解支配行为的原则。我们的第一个发现是,与随机网络相比,小世界网络中的价格更大,交易效率也明显更低。我们的第二个发现是,网络中的位置并不是价格的重要决定因素。对价格动态的研究表明,走在最便宜(因此也是最活跃)路径上的交易员会抬高价格,而离开这些路径的交易员则会压低价格。我们构建了一个基于代理的模型(ABM)来体现这一经验法则。对这种ABM的模拟得出了与实验结果一致的宏观模式。最后,我们将ABM外推到更大的随机和小世界网络,并发现网络拓扑结构仍然是定价和效率的关键决定因素。

A Policy Compass for Ecological Economics 生态经济学的政策指南
Pub Date : 2019-03-13 DOI: 10.13140/RG.2.2.30052.01924
Michèle Friend
A policy compass indicates the direction in which an institution is going in terms of three general qualities. The three qualities are: suppression, harmony and passion. Any formal institution can develop a policy compass to examine the discrepancy between what the institution would like to do (suggested in its mandate) and the actual performance and situation it finds itself in. The latter is determined through an aggregation of statistical data and facts. These are made robust and stable using meta-requirements of convergence. Here, I present a version of the compass adapted to embed the central ideas of ecological economics: that society is dependent on the environment, and that economic activity is dependent on society; that we live in a world subject to at least the first two laws of thermodynamics; that the planet we live on is limited in space and resources; that some of our practices have harmful and irreversible consequences on the natural environment; that there are values other than value in exchange, such as intrinsic value and use value. In this paper, I explain how to construct a policy compass in general. This is followed by the adaptation for ecological economics. The policy compass is original, and so is the adaptation. The compass is inspired by the work of Anthony Friend, Rob Hoffman, Satish Kumar, Georgescu-Roegen, Stanislav Schmelev, Peter Soderbaum and Arild Vatn. In the conclusion, I discuss the accompanying conception of sustainability.
政策指南针根据三个一般品质表明一个机构的前进方向。这三种品质是:压抑、和谐、激情。任何正式机构都可以制定一个政策指南,以检查机构希望做的事情(在其任务中建议)与实际表现和情况之间的差异。后者是通过汇总统计数据和事实来确定的。使用收敛的元需求使它们变得健壮和稳定。在这里,我提出了一个版本的指南针,以嵌入生态经济学的核心思想:社会依赖于环境,经济活动依赖于社会;我们生活在一个至少符合热力学前两条定律的世界;我们生活的星球空间和资源是有限的;我们的一些做法对自然环境造成了有害和不可逆转的后果;交换价值之外还有其他价值,如内在价值和使用价值。在本文中,我一般解释了如何构建政策指南针。其次是对生态经济学的适应。政策指南是原创的,调整也是原创的。指南针的灵感来自安东尼·弗兰德、罗布·霍夫曼、萨蒂什·库马尔、乔治斯库·罗根、斯坦尼斯拉夫·施米列夫、彼得·索德鲍姆和阿利德·瓦恩的作品。在结论部分,我讨论了伴随的可持续性概念。

TAXATION OF A GMWB VARIABLE ANNUITY IN A STOCHASTIC INTEREST RATE MODEL 随机利率模型下GMWB可变年金的税收
Pub Date : 2019-01-31 DOI: 10.1017/ASB.2020.29
Andrea Molent
Modeling taxation of Variable Annuities has been frequently neglected but accounting for it can significantly improve the explanation of the withdrawal dynamics and lead to a better modeling of the financial cost of these insurance products. The importance of including a model for taxation has first been observed by Moenig and Bauer (2016) while considering a GMWB Variable Annuity. In particular, they consider the simple Black-Scholes dynamics to describe the underlying security. Nevertheless, GMWB are long term products and thus accounting for stochastic interest rate has relevant effects on both the financial evaluation and the policy holder behavior, as observed by Goudenege et al. (2018). In this paper we investigate the outcomes of these two elements together on GMWB evaluation. To this aim, we develop a numerical framework which allows one to efficiently compute the fair value of a policy. Numerical results show that accounting for both taxation and stochastic interest rate has a determinant impact on the withdrawal strategy and on the cost of GMWB contracts. In addition, it can explain why these products are so popular with people looking for a protected form of investment for retirement.
可变年金的税收建模经常被忽视,但对其进行会计处理可以显著改善对提取动态的解释,并导致这些保险产品的财务成本更好的建模。Moenig和Bauer(2016)在考虑GMWB可变年金时首先观察到纳入税收模型的重要性。特别是,他们考虑简单的布莱克-斯科尔斯动力学来描述潜在的安全性。然而,根据Goudenege等人(2018)的观察,GMWB是长期产品,因此考虑随机利率对财务评估和保单持有人行为都有相关影响。在本文中,我们研究了这两个要素在GMWB评价中的结果。为此,我们开发了一个数字框架,使人们能够有效地计算政策的公允价值。数值结果表明,考虑税收和随机利率对GMWB合同的退出策略和成本有决定性影响。此外,这也可以解释为什么这些产品如此受那些寻求一种有保障的退休投资形式的人的欢迎。

Quantum model for price forecasting in financial markets 金融市场价格预测的量子模型
Pub Date : 2019-01-30 DOI: 10.13140/RG.2.2.32897.92006
J. Subias
The present paper describes a practical example in which the probability distribution of the prices of a stock market blue chip is calculated as the wave function of a quantum particle confined in a potential well. This model may naturally explain the operation of several empirical rules used by technical analysts. Models based on the movement of a Brownian particle do not account for fundamental aspects of financial markets. This is due to the fact that the Brownian particle is a classical particle, while stock market prices behave more like quantum particles. When a classical particle meets an obstacle or a potential barrier, it may either bounce or overcome the obstacle, yet not both at a time. Only a quantum particle can simultaneously reflect and transmit itself on a potential barrier. This is precisely what prices in a stock market imitate when they find a resistance level: they partially bounce against and partially overcome it. This can only be explained by admitting that prices behave as quantum rather than as classic particles. The proposed quantum model finds natural justification not only for the aforementioned facts but also for other empirically well-known facts such as sudden changes in volatility, non-Gaussian distribution in prices, among others.
本文描述了一个实际的例子,其中股票市场蓝筹股价格的概率分布被计算为限制在势阱中的量子粒子的波函数。这个模型可以很自然地解释技术分析师使用的几个经验法则的运作。基于布朗粒子运动的模型不能解释金融市场的基本方面。这是因为布朗粒子是一种经典粒子,而股票市场的价格表现得更像量子粒子。当一个经典粒子遇到障碍或潜在障碍时,它可能反弹或克服障碍,但不是同时发生这两种情况。只有量子粒子能够在势垒上同时反射和传输自身。这正是股市价格在发现阻力位时所模仿的:它们部分反弹,部分克服阻力位。这只能通过承认价格表现为量子而不是经典粒子来解释。提出的量子模型不仅为上述事实,而且为其他经验上众所周知的事实,如波动性的突然变化、价格的非高斯分布等,找到了自然的理由。

Asymmetric Connectedness of Fears in the U.S. Financial Sector 美国金融业恐惧的非对称连通性
Pub Date : 2018-10-29 DOI: 10.2139/ssrn.3274538
Jozef Baruník, Mattia Bevilacqua, R. Tunaru
We study how shocks to the forward-looking expectations of investors buying call and put options transmit across the financial system. We introduce a new contagion measure, called asymmetric fear connectedness (AFC), which captures the information related to "fear" on the two sides of the options market and can be used as a forward-looking systemic risk monitoring tool. The decomposed connectedness measures provide timely predictive information for near-future macroeconomic conditions and uncertainty indicators, and they contain additional valuable information that is not included in the aggregate connectedness measure. The role of a positive/negative "fear" transmitter/receiver emerges clearly when we focus more closely on idiosyncratic events for financial institutions. We identify banks that are predominantly positive/negative receivers of "fear", as well as banks that positively/negatively transmit "fear" in the financial system.
我们研究购买看涨期权和看跌期权的投资者对前瞻性预期的冲击如何在整个金融体系中传导。我们引入了一种新的传染度量,称为不对称恐惧连通性(AFC),它捕获了期权市场双方与“恐惧”相关的信息,可以用作前瞻性系统性风险监测工具。分解的连通性度量为近期宏观经济状况和不确定性指标提供了及时的预测信息,并且它们包含了未包含在总连通性度量中的附加有价值的信息。当我们更密切地关注金融机构的特殊事件时,积极/消极“恐惧”的传递者/接收者的作用就会清晰地显现出来。我们确定了主要是“恐惧”的积极/消极接受者的银行,以及在金融体系中积极/消极传播“恐惧”的银行。

Recently, along with the emergence of food scandals, food supply chains have to face with ever-increasing pressure from compliance with food quality and safety regulations and standards. This paper aims to explore critical factors of compliance risk in food supply chain with an illustrated case in Vietnamese seafood industry. To this end, this study takes advantage of both primary and secondary data sources through a comprehensive literature research of industrial and scientific papers, combined with expert interview. Findings showed that there are three main critical factor groups influencing on compliance risk including challenges originating from Vietnamese food supply chain itself, characteristics of regulation and standards, and business environment. Furthermore, author proposed enablers to eliminate compliance risks to food supply chain managers as well as recommendations to government and other influencers and supporters.
近年来,随着食品丑闻的不断发生,食品供应链面临着越来越大的食品质量安全法规和标准合规压力。本文以越南海产品行业为例,探讨食品供应链合规风险的关键因素。为此,本研究通过对工业和科学论文的综合文献研究,结合专家访谈,利用一手和二手数据来源。研究结果表明,影响合规风险的主要关键因素组包括越南食品供应链本身的挑战、法规和标准的特点以及商业环境。此外,作者还提出了消除食品供应链管理者合规风险的推动因素,以及对政府和其他影响者和支持者的建议。

Changing the Direction of the Economic and Demographic Research 改变经济与人口研究方向

A simple but useful method of reciprocal values is introduced, explained and illustrated. This method simplifies the analysis of hyperbolic distributions, which are causing serious problems in the demographic and economic research. It allows for a unique identification of hyperbolic distributions and for unravelling components of more complicated trajectories. This method is illustrated by a few examples. They show that fundamental postulates of the demographic and economic research are contradicted by data, even by precisely the same data, which are used in this research. The generally accepted postulates are based on the incorrect understanding of hyperbolic distributions, which characterise the historical growth of population and the historical economic growth. In particular, data used, but never analysed, during the formulation of the Unified Growth Theory show that this theory is based on fundamentally incorrect premises and thus is fundamentally defective. Application of this simple method of analysis points to new directions in the demographic and economic research. It suggests simpler interpretations of the mechanism of growth. The concept or the evidence of the past primitive and difficult living conditions, which might be perhaps described as some kind of stagnation, is not questioned or disputed. It is only demonstrated that trajectories of the past economic growth and of the growth of population were not reflecting any form of stagnation and thus that they were not shaped by these primitive and difficult living conditions. The concept or evidence of an explosion in technology, medicine, education and in the improved living conditions is not questioned or disputed. It is only demonstrated that this possible explosion is not reflected in the trajectories of the economic growth and of the growth of population.
介绍了一种简单而实用的求倒数法,并对其进行了说明和说明。这种方法简化了在人口和经济研究中引起严重问题的双曲分布的分析。它允许对双曲分布进行独特的识别,并解开更复杂轨迹的组成部分。通过几个例子说明了这种方法。它们表明,人口和经济研究的基本假设与数据相矛盾,甚至与本研究中使用的完全相同的数据相矛盾。普遍接受的假设是基于对双曲线分布的错误理解,而双曲线分布是历史上人口增长和历史上经济增长的特征。特别是,在统一增长理论的形成过程中,使用但从未分析过的数据表明,该理论建立在根本错误的前提之上,因此存在根本缺陷。这种简单的分析方法的应用为人口和经济研究指明了新的方向。它提出了对增长机制的更简单的解释。过去原始和艰苦的生活条件的概念或证据,可能被描述为某种停滞,没有受到质疑或争议。这只是表明,过去经济增长和人口增长的轨迹没有反映任何形式的停滞,因此它们不是由这些原始和困难的生活条件形成的。技术、医学、教育和生活条件改善方面的爆炸式发展的概念或证据是不容质疑或争议的。这只是表明,这种可能的爆炸并没有反映在经济增长和人口增长的轨迹上。
