A non-Maxwellian collision kernel is employed to study the evolution of wealth distribution in a multi-agent society.The collision kernel divides agents into two different groups under certain conditions. Applying the kinetic theory of rarefied gases, we construct a two-group kinetic model for the evolution of wealth distribution. Under the continuous trading limit, the Fokker–Planck equation is derived and its steady-state solution is obtained. For the non-Maxwellian collision kernel, we find a suitable redistribution operator to match the taxation. Our results illustrate that taxation and redistribution have the property to change the Pareto index. 展开更多

In this article, the authors consider the optimal portfolio on tracking the expected wealth process with liquidity constraints. The constrained optimal portfolio is first formulated as minimizing the cumulate variance between the wealth process and the expected wealth process. Then, the dynamic programming methodology is applied to reduce the whole problem to solving the Hamilton-Jacobi--Bellman equation coupled with the liquidity constraint, and the method of Lagrange multiplier is applied to handle the constraint. Finally, a numerical method is proposed to solve the constrained HJB equation and the constrained optimal strategy. Especially, the explicit solution to this optimal problem is derived when there is no liquidity constraint. 展开更多

This paper describes a model in which a representative investor's preference depends on both the consumption history consumption and his wealth. Thus, the investor accumulates wealth not only for the sake of consumption history but also for wealth. We examine the implication for consumption, portfolio choice. We solve the consumption portfolio choice problem and provide the optimal policy. The optimal solution to the problem shows that the preference for wealth and consumption formation will affect the investor's optimal portfolio policy. For the purpose of further research, we also calculate the steady-state distribution of habit-consumption ratio. 展开更多

This paper aims, first of all, to examine the two fundamental treatments of the complex and very broad notion of chrematistikd (money-making) and its links with the notion of oikonomia (economics), outlining a fundamental division between natural and unnatural art of money-making. The two different arts of money-making are based on two very different psychological attitudes: in the first case, desire is channeled, managed, and organized by practical wisdom with a view to a further end; in the second case, desire is an end unto itself, insatiable, boundless and contrary to the commands of practical wisdom. Only in the first case there is a "true wealth", that is a wealth oriented toward a good life that constitutes the end (telos) and the limit (peras) of the wealth itself. The conclusion is that, for the Stagirite, wealth is not an evil, nor, in itself, is the pursuit of wealth, that is, the art of money-making, because if it is rightly organized and oriented in function of the end, it constitutes the conditio sine qua non of a life that is good, ordered and happy for the individual and for the city 展开更多

Several strategic metals, elements and energy resources are about to run into scarcity in the near future under the present paradigm of use. A global systems model has been developed (WORLD) to assess the issue of scarcity and its implications for society. We show that scarcity may lead to "peak wealth", "peak population", "peak waste" and "peak civilization", unless urgent counter-measures are systematically undertaken. Materials that underpin modern society may become unavailable for global mass production of goods. The material volumes that can be supplied from fossil reserves will be reduced with respect to today and resources will go up in price. The future resource supply is unsustainable without comprehensive recycling. The creation of wealth from conversion of resources and work, as well as the current extensive borrowing from the future, cause concerns that peaking energy and materials production may lead to "peak wealth" and the end of the golden age we live in. Our policy recommendations are that governments must take this issue seriously and must immediately start preparing legislations to close material cycles, optimize energy use and minimize irreversible material losses. Research efforts need to be based on systems thinking and a concerted effort is needed. 展开更多

It is intellectual capital. Because intellectual capitals increase GDP of nations, and create wealthfor nations. ICs have accumulated knowledge, and ICs make innovations for company via this knowledge. Forexample, American economy has full of ICs, corporate CEOs. CEOs make country rich. CEOs are intellectualcapital. For example, Steve Jobs created smart phone, and Apple becomes no.1 in markets. Therefore, ICs(corporate CEOs) make a country richer. Intellectual capital is related with human resource management. Therefore,a country make investment to human resource management to create wealth of nations and intellectual capitals. 展开更多

This paper is a theological reflection on the theology of wealth in Africa--its nature, philosophy, and sustaining factors. Through the methodology of theological reflections, the paper finds out that the theology of wealth, though difficult to describe, is sustained on the African continent by economic hardship, the influence of some preachers of the theology of wealth, and the availability of improved facilities for disseminating the content of the theology of wealth. It also finds out that the entire philosophy of the theology of wealth is biblically, theologically, and ethically deficient. Biblically, it adapts parts of scripture to suit its teachings. Theologically, it puts forth viewpoints that are foreign to theological thought. Ethically, it is a means of exploiting congregants. The paper concludes with a recommendation that the content and nature of the theology of wealth must be highlighted and thoroughly explained to both clergy and membership of different denominations so that all will be safeguarded against the impact of this false gospel on their lives. 展开更多

This research provides a survey of literature that contextualizes the research's aim of examining factors impacting students' aspirations and wealth expectations in Lebanon. To highlight Lebanese higher education students' youth's expectations of their future wealth, one should understand the four main factors that affect youth's hopes and aspirations: social, financial, cultural, and educational. Questionnaires are used to identify and assess how young individuals perceive their future wealth expectations. The developed surveys provide useful and reliable data to analyze the effects of many factors on wealth expectations and outcomes for youth. The collected information is of particular importance for identifying and assessing how factors shape wealth expectations and outcomes for youth. The samples used in this research analysis are restricted to college students only. The research findings shed light on the most crucial variables/factors that should be studied and analyzed. Once these factors are pinpointed and explained, a clear idea about higher education students' wealth expectations is formed. Short- and long-term expectations are taken into consideration and evaluated to formulate a basic idea about Lebanese youth. 展开更多

We find ourselves at the end of a national election season, one cycling through a particularly depressed economic situation, but Americans, a generally hopeful, forward looking lot have become accustomed to growing incivility and resentment in their politics. This resentment stems from what Albert Borgmann defines as the character of our late modern age--we are both sullen and hyper in our daily lives. This situation comes at the intersection of long developing modern elements stemming from the control of nature via a universal scientific method at the behest of our own aggressive pursuit of individuality. The nature of our lives are in turn reinforced and reproduced by our frenetic militarized mobilization to recapture political and economic leadership at an international level. This goal, spurred on by an elite oligarchical vanguard, is reinforced by a "wealth defense industry," developed in the late 20th century, designed to protect the wealth of our own elite class. This industry has stripped traditional cultural and academic sites of their ability or interest in interrogating the present status quo, and has rendered them fiat, uninspiring, and indolent in the face of growing income inequities and injustice. American political science has essentially become, in the vein of Marita Sturken's work, kitschified--facile, glib, and easily reproduced so as to act as a balm to our bruised, sullen egos, longing for an age of innocence-a smooth and glassy yet opaque history that eases our consciences and forgives the growing antidemocratic practices of our civil oligarchy. 展开更多

Commercially important polyphagous tropical tasar silk insect, Antheraea mylitta Drury is distributed along central India (12-31 ° N latitude, 72-96° E longitude), which on adaptation formed in to forty four ecoraces of varied phenotypes. Its wild ecoraces like Raily, Modal, Jata, Sarihan, Laria, Bhandara and Andhra, besides domesticated Daba and Sukinda are contributing for livelihood of forest based aboriginals. However, the deforestation and extensive collection of nature grown cocoons led to declination of wild population and even have endangered few ecoraces. The government and Non Government Organizations (NGOs), although promote ecorace conservation, it could upkeep the insect wildlife only to limited extent. But the forest department with associated self help societies has advantage in conserving tasar insect as prospective forest wealth, with better knowledge and access to its habitats. The co-ordinate efforts from forest, sericulture departments to participate native aboriginals of such societies can facilitate conserving tasar-biodiversity as most feasible forest associated resource. 展开更多

This is not only the problem of poor people living in specific regions but also the problem of all people in general. Poverty is expected to decrease as the welfare level increases. The World Bank predicts that extreme poverty will disappear until 2030 but mentions significant hesitations in achieving this objective. Even though extreme poverty will have actually disappeared in 2030, the deep gap between the richest 20% and the poorest 20% will continue to maintain its presence. There are many reasons for poverty arising from individuals such as illiteracy, inexperience, and laziness. However, there are many reasons for poverty beyond the individual such as the management of the capital by a small group of people. While the capital continuously increases under the control of a narrow group, poor community deprived of increasing welfare benefits from it slightly and too late. In this case, the solutions that individuals striving to live below the poverty line can find on their own in order to keep alive remain quite limited. Islam has a shorter term solution for welfare share: Transferring a small amount of high-income group’s wealth to the low-income group. Through this worship called zakat, it is aimed to rid poor people of desperation. It is not theoretically impossible todevelop a method to reduce income inequality by taking the worship of zakat as a model. 展开更多

Entertainment and education consumption partly reflects people’s living standards.In order to study the influential factors of entertainment and education consumption of Chinese people in the second decade of the 21st century,this paper uses the data from 2010 to 2018 in China Family Panel Studies(CFPS)and the multiple linear regression analysis in econometrics to evaluate the impact of the increase of total household assets on the consumption of entertainment and education in China through Stata software.The results show that the increase in household assets promotes entertainment and education consumption.However,the promoting effect gradually decreased from 2010 to 2018.In addition,high housing price took in a large amount of family income and impeded the consumption of entertainment and education.The decline in people’s preference for entertainment and education consumption in recent years,to some extent,means a rise in living pressure and a decline in the quality of life in China. 展开更多

As critical piece of China's gradualist economic transition, domestic price reform still faces major challenges. In particular, factor price, which is still tightlycontrolled and not market-based, is lower than market equilibrium price. Factor price distortion not only reduces market efficiency but also affects wealth distribution. Subsequent wealth transfer has, over the past ten to fifieen years, created a powerful vested interests and spawned social resentment, both of which may constitute major hazards in China's future reform and development. Keeping in mind that China will have to address factor price distortion in its next step of reform, this paper takes stock of China's journey toward price rejorm; examines the relationship among factor price distortion, previous economic growth, and policy; and estimates' the size of resulting wealth transfer. 展开更多

Francis Scott Key Fitzgerald was born in St. Paul,MInnesota on September24,1896. He was the only son of an upper middle class Catholic family. While he was at Princeton university,the young Fitzgerald developed his talent in writing. When the First World War broke out,he enlisted in the army,and in a training camp in Alabama,he met and fell in love with Zelda sayre,the southern belle who became his wife and who was the model for most of the beautiful and gay heroines of his fiction. His life with her was a mixture of great happiness and great misery and pain. In 1925,Fitzgerald published his most famous novel "The Great Gatsby". Before long,his wife became mentally ill. Fitzgerald declined as a writer. He worked regularly as a script-writer in Hollywood from 1937 to 1939,when he succumbed to alcoholism. He died of heart attack in 1940. His wife,Zelda,was sent to a sanitarium and died in a fire started by herself in the sanitarium。 展开更多
