Optimal investment of an insurer with regime-switching and risk constraint

We investigate an optimal investment problem of an insurance company in the presence of risk constraint and regime-switching using a game theoretic approach. A dynamic risk constraint is considered where we constrain the uncertainty aversion to the ‘true’ model for financial risk at a given level. We describe the surplus of an insurance company using a general jump process, namely, a Markov-modulated random measure. The insurance company invests the surplus in a risky financial asset whose dynamics are modeled by a regime-switching geometric Brownian motion. To incorporate model uncertainty, we consider a robust approach, where a family of probability measures is cosidered and the insurance company maximizes the expected utility of terminal wealth in the ‘worst-case’ probability scenario. The optimal investment problem is then formulated as a constrained two-player, zero-sum, stochastic differential game between the insurance company and the market. Different from the other works in the literature, our technique is to transform the problem into a deterministic differential game first, in order to obtain the optimal strategy of the game problem explicitly.     

保障性住房政策演变下住房租赁市场发展研究——以德国、美国为例

完善住房租赁市场一直是保障中低收入者住房需求的重要途径。在保障性住房政策的推动下,世界各国的住房租赁市场都取得了进展,并呈现出一定的规律。营利型租赁与成本型租赁在住房租赁市场的发展过程中总是共同发展,相互制约。只有实施以成本型租赁成熟化为目标的保障性住房租赁政策才能最终为中低收入者服务,反之将导致成本型租赁的边缘化。结合德国、美国的实际经验来探讨住房租赁市场的演变规律,并为我国的保障性住房建设提出建议。

本文在分析当前中国互联网与传统社交网站发展现状基础上,比较了传统社交网站的盈利模式,以人人网为例分析其盈利状况,并运用五力模型分析传统社交网站面临的挑战。由于我国传统社交网站发展仍然存在较多问题,因此需要制定相关措施加以解决,如明确自身定位,发展垂直社交;知悉用户需求,提升服务质量;联手本地商家,活用SoLoMo模式;加强监管,保护知识产权。     

关于新增贷款与国内生产总值关系的研究

近年来,我国GDP增长与新增贷款的关系发生了变化,实证分析表明,新增贷款对GDP的贡献度下降,这意味着维持GDP增长需要投入更多的信贷,GDP高增长面临的信贷资源约束加大。文章从经济结构变化和信贷结构变化两个层面分析了导致这种变化的主要原因,并就进一步完善货币信贷调控提出相关政策建议。     

China as a Global Manufacturing Powerhouse： Strategic Considerations and Structural Adjustment

This study examines the nature and consequences of China＇s rise to the center of world economic affairs through manufacturing-led development. Our historical analysis shows that China is still well short of the point in its developmental process where its growth might be reasonably expected to slow, or the energy, resource and carbon intensity of growth to recede. The study argues that the current trajectory of industrialization will have to be altered when China becomes more actively engaged in dealing with structural issues at home and abroad against the background of the unwinding of global imbalances. One profitable strategy that China might employ wouM be to approximate the incredibly fruitful mass-market integration efforts of the USA that eventually elevated it to its position of global primacy. The cyclical re-emergence of excess capacity in Chinese heavy industry, serious questions about the medium term ability of other major regions to accommodate further large gains in Chinese market share, and the stark conflict between the contemporary style of industrial development and the health of the biosphere indicate strongly that now is the time to catalyze the required adjustment and reform processes that will underpin sustainable long-run prosperity.

国有商业银行费用偏好与组织绩效的实证分析

单一国有产权结构、出资人监督缺位和委托代理问题共同决定了国有商业银行费用扩张偏好.实证结果表明,费用规模扩张侵蚀了出资人利润性收益空间,成为国有商业银行利润率指标偏低的解释因素.因此,国有商业银行制度变迁必然包含能够抑制费用偏好的制度工具创新.政府宏观经济目标的退出可以使出资人硬化利润约束,但在政府效用函数不可能全面退出国有商业银行的现实背景中,通过引进在位寡头之间的竞争可以为国有商业银行利润目标约束硬化提供外在制衡条件;同时,产权多元化改革基础上的银行治理结构完善则是解决委托-代理问题下经营者费用偏好问题的彻底措施.     

A Micro-Approach for Testing Marx's LTRPF: Evidence from Greece, 2000 and 2009

This article develops a novel micro-approach for the empirical evaluation of Marx's law of the tendency of the rate of profit to fall. Contrary to the traditional method which uses national macroeconomic data, this approach utilises data taken directly from company reports and accounts. The principal advantage of this approach is that it provides an accurate measurement of the value composition of capital, devoid of the measurement limitations of the traditional method regarding variable capital which stem from the inability to distinguish productive from unproductive labour. A disadvantage, however, is that this approach does not cover the entire national economy. The application of the proposed micro-approach to the ongoing Greek crisis yields results which are congruent with the traditional method and reinforce other recent studies linking the current crisis with low profitability.     

The Greek economic crisis: causes and alternative policies

The Greek economic crisis is primarily structural and the result of an international economic impasse that developed in 2007, with devastating implications for the struggling peripheral economies of Europe. This article suggests that falling profitability led to the stagnation of profits, which in turn discouraged new investment, decreased production and increased unemployment. The resulting recessionary economic environment, in conjunction with the mounting public debt and the austerity policies imposed on the Greek economy by the so-called ‘troika’ of creditors in 2010, has decimated the Greek economy even further, causing one of the worst economic crises since the Second World War. The article also provides some broad guidelines for an alternative economic policy.
