随机利率下的复合Poisson-Geometric风险模型及破产概率

本文主要研究的是在随机利率下保费收入为复合Poisson-Geometric过程的风险模型,在随机利率为levy过程的情况下,得到了破产概率满足的积分方程,以及得到最终破产概率的上下界所满足的积分不等式,以此作为保险公司经营的预警信号更具有现实意义。

A model of Chinese central government

Why was the Chinese State able to promote economic growth during the reform era, yet has been unable to do so over the previous 30 years? In this article, we focus on a specific aspect of the question, which will contribute to the development of a more comprehensive explanation: the specific institutional arrangement that may induce the autocratic government to adopt growth‐enhancing policies. We consider a standard political‐agency model (Besley, 2006) where the incumbent leader may or may not be congruent, and where, to maintain power, both leader types need the support of the selectorate, an elite group having a say in selecting the leader, as well as associated access to special privileges. Primarily, we find that in autocracies, without electoral discipline to restrain the opportunistic behaviour of a leader, the size of the selectorate should be intermediate; if it is too small, the selectorate is captured by the leader and has no disciplinary role, but if too big, the leader's incentives are diluted.

China's economic growth and its real exchange rate

The shocks that underlie China's comparatively rapid growth include gains in productivity, factor accumulation and policy reforms that increase allocative efficiency. The well-known Balassa–Samuelson hypothesis links productivity growth in tradable industries with real appreciations. Yet it relies heavily on the law of one price applying for tradable goods, against which there is now considerable evidence. In its absence, other growth shocks also affect the real exchange rate by influencing relative supply or demand for home product varieties. This paper investigates the pre-conditions for the Balassa–Samuelson hypothesis to predict a real appreciation in the Chinese case. It then quantifies the links between all growth shocks and the Chinese real exchange rate using a dynamic model of the global economy with open capital accounts and full demographic underpinnings to labor supply. The results suggest that financial capital inflows most affect the real exchange rate in the short term, while differential productivity is strong in the medium term. Contrary to expectation, in the long term demographic forces prove to be weak relative to changes in the skill composition of the labor force, which enhances services sector performance and depreciates the real exchange rate.     

A lottery-preference-based explanation of realized kurtosis puzzle in Chinese stock market

High kurtosis corresponds to fat tails on both sides and under risk-aversion assumption investors’ dislike of left-tail loss outweighs their preference for right-tail gain. Therefore, high kurtosis characteristic of stock should predict high expected returns. However, the high-frequency-data-based empirical results on Chinese stock market are just the opposite, which we refer to as the ‘realized kurtosis puzzle’. Using the double sorts and firm-level cross-sectional regression methods, we further demonstrate investors’ preference for lottery-like stocks or lottery preference is key to solve the puzzle. Our further empirical research verifies stocks with higher retail investors’ shareholding proportion and unavailable for short show stronger ‘realized kurtosis puzzle’. In addition, the puzzle is particularly significant in high lottery preference periods while less apparent in low lottery preference times.

酸性蚀刻废液中铜的形态分布及电化学行为

在氯化物体系中，Cu^＋、Cu^2＋均能与Cl^-形成多种形态的配合物，存在形态及分布与溶液中各离子浓度有关。由于各种配合物的稳定性不同，致使Cu^＋、Cu^2＋氯化物的溶解度及电极电位也不同。对酸性蚀刻废液中铜的存在形态、电化学行为、以及采用隔膜电解法回收工艺的可行性进行了分析。
