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

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

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

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

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
