成长冲动与风险对冲:经济政策不确定性如何影响企业海外并购

本文扎根于中国转型经济背景,提出了在经济政策不确定性影响下企业海外并购的两大动因,即成长冲动和风险对冲.同时认为:经济政策不确定性使得企业内生有机成长方式、外在本土并购扩张方式受到了阻碍;企业面临着因融资成本、非经营性成本增加带来的风险;此时,海外并购便成为企业的最佳策略.本文以2008-2018年中国沪深两市A股上市公司为样本,实证检验了上述影响机制.研究结果显示:经济政策不确定性较高时,在成长冲动和风险对冲的驱动下,企业倾向于使用海外并购来替代本土并购,且这种替代作用在非国有企业中更为明显.机制检验表明:成长冲动强烈、融资成本和非经营性成本较高、风险承担能力弱的企业更倾向于采取海外并购策略,以规避经济政策不确定性的影响.     

INTERNATIONAL RESERVE MANAGEMENT: A DRIFT‐SWITCHING REFLECTED JUMP‐DIFFUSION MODEL

We study the cost of shocks, that is, jump risk, with respect to reserve management when the reserve process is formulated as a drift‐switching jump diffusion with a reflecting barrier at 0. Inspired by the Brownian drift switching model, our model results in a more realistic dynamic behavior of international reserves than the buffer stock model. The new model can capture both the jump behavior in reserve dynamics and the leptokurtic feature of the increment distribution which has a higher peak and two asymmetric heavier tails than the normal distribution. Through the selection of an initial distribution that reflects certain steady state behaviors, the reserve process becomes a regenerative process. This selection enables us to derive a closed‐form expression for the total expected discounted cost of managing reserves, thus helping us to numerically find management strategies that minimize costs. The numerical results show that shocks at the reserve level have a significant effect on reserve management strategies and that model misspecification can result in nonnegligible additional costs.

An exceptional development pattern

This paper investigates India's exceptional development pattern, specifically the major importance of information technology services (ITS), and compares it with China's development pattern. Both countries want to develop capabilities for carrying out the innovation of technologies that compete at the state-of-the-art in the world market. The paper posits that technological/economic success in the contemporary world market requires the ability to innovate complex technologies and complex technology-related services. The share of trade represented by complex technologies is compared with the “high-tech” share. The trading patterns of the two countries are compared using United Nations data. Two case studies of Indian ITS companies are then compared with two case studies of Chinese manufacturing companies. Historical and cultural differences appear to explain some of the differences in the development patterns of the companies located in the two countries.

Analysis on the internal mechanism forming the capital operation venture of nation-owned enterprises

According to the Capital of Karl Marx, capital aims at realizing the value maintenance and increment during the process of its cycle and turnover. Without the conditions of capital＇s cycle and turnover, it will break off. This will furthermore bring an obstacle to the value maintenance and increment of capital, which is the root of capital operation venture and is also the internal mechanism forming the capital operation venture of nation-owned enterprises.
