We examine the dynamic adjustment of cash holdings of publicly traded Chinese firms over the period 1998-2006. The empirical evidences are supportive of the dynamic trade-off theory of cash holdings. Importantly, there is strong evidence to support asymmetric adjustments. That is, the adjustments from above the target are significantly faster than adjustments from below. In addition, adjustment speeds are heterogeneous for firms facing differential adjustment costs. In particular, adjustment speed is negatively related to firm size, but positively related to the deviation from the target. Furthermore, in terms of adjustment method, Chinese listed firms make adjustments to their targets primarily through internal financing, while debt financing and dividend payment play a minimal role. Finally, we find that the precautionary motive arising from financial constraints explains the cash holdings adjustment behaviors of Chinese Listed firms well.

The paper studies the effect of social capital on the firms’ debt capacity and capital structure in China. We measure the social capital of China’s 31 provinces through four indexes: the number of NGOs per capita, the index of trust among peoples, the volunteer blood donation ratio of civics, and the money and material donation of civics. The results show that in those areas with more social capital, the firms are more likely to have higher debt ratio and longer debt maturity, and the firms can get debt financing with less tangible assets. And in those districts, the firms are easier to obtain bank credits and trade credits. The paper has two contributions to the economics literature: first, it confirms the economic value of social capital from a micro view; second, it provides a new perspective to understand the firms’ capital structure choice.

Multiunit structure can internalize the managerial market to promote competition among subsidiary managers, and create an internal capital market within firms to alleviate external financing constrains, and it also may lead to diversification to lower the operation risk and regulation. While it brings in more agency problem created by subsidiary managers, causing the efficiency of internal capital market and diversification confusing. Using the data of listed firms in China, an emerging market, this paper examines the efficiency of multiunit structure within the firm, investigating the influence on capital allocation and firm performance. We find that multiunit structure is better in emerging market since it is efficient in capital allocation, reducing the inefficient investment by reducing the overinvestment and alleviating the underinvestment, and the bright side of multiunit structure dominates the agency problem associated, thus beneficial for firm performance, both short-term and long-term accounting returns. In less developed capital market under current situation, multiunit structure is better.

The long-run underperformance of the initial public offerings is one of the three hot issues in IPO research area,until 2000,the scholars in China began to research it,hence,the related theory is far from absent,therefore,many theories need to be completed. The article studied the long-run performance of 174 shares issued in Small and Medium-sized Board from the day after the first trading day to three years.It found that the shares show underperformance since the first month after its going to public,which will continue to the second year.But the shares showed strong performance compared with the Shenzhen A-share Composite Index.

China began allowing short selling and margin trading in 90 stocks in March 2010. This event provides an opportunity to test the relative effect of margin trading and short selling. We find the prices of these 90 stocks decrease, on average, relative to peer stocks in China and cross-listed H-shares, suggesting that short selling dominates margin trading effects. Contrary to the regulators? intention, and recent empirical evidence, liquidity declines in the shortable stocks. This may imply avoidance of these stocks by uninformed investors. There is also evidence of higher bid-ask spreads following the regulation change.

This paper empirically models China’s stock prices using conventional fundamentals: corporate earnings, risk-free interest rate, and a proxy for equity risk premium. It uses the estimated long-run stock price misalignments to date booms and busts, and analyses equity market reforms and excess liquidity as potential drivers of these stock price misalignments. Our results show that China’s equity prices can be reasonable well modelled using fundamentals, but that various booms and busts can be identified. Policy actions, either taking the form of deposit rate changes, equity market reforms or excess liquidity, seem to have significantly contributed to these misalignments.

This paper examines the impact of renminbi revaluation on foreign firm valuation and, by implication, firm prospects. To deal with the potential endogeneity of exchange rate movements, we consider not just official announcements of exchange rate policy but also 27 instances of market-perceived changes in China’s currency policy driven by domestic or foreign political pressure. Using information on 12,300 firms in 44 countries, we find that stock returns increased with renminbi revaluation expectations. This reaction was related as much to improved market sentiment as to specific trade channels, however. In terms of trade channels, we find that expectations of renminbi appreciation reduce the relative stock returns of firms providing components and raw materials to China as inputs for the country’s exports. There is also some evidence that expectations of renminbi appreciation reduce the stock prices of financiallyconstrained firms.

This paper investigates the dynamic and long-run relationships between monetary policy and asset prices in China using monthly data from June 2005 to September 2010. Johansen’s cointegration approach based on vector autoregression (VAR) and Granger causality test are used to identify the long-run relationships and directions of causality between asset prices and monetary variables. Empirical results show that monetary policies have little immediate effect on asset prices, suggesting that Chinese investors may be ‘irrational’ and ‘speculative’. Instead of running away from the market, investors rush to buy houses or shares whenever tightening monetary actions are taken. Such seemingly irrational and speculative behavior can be explained by various social and economic factors, including lack of investment channels, market imperfections, cultural traditions, urbanization and demographic changes. The results have two important policy implications. First, China’s central bank has not used and should not use interest rate alone to maintain macro-economic stability. Second, both monetary and non-monetary policies should be deployed when asset bubbles loom large to avoid devastating consequences when they burst.

投资组合保险策略因其规避下方风险同时不失去从上升市场中获利而受到欢迎。正是由于对下方风险的规避其收益率不再服从对数正态分布的假设，因此，传统的绩效评价准则如方差、SHARPE比率不再适用，而基于分布的随机占优准则是一个良好的替代。由于投资组合保险策略之间具有较强的相关性，本文在随机占优准则实证中采用subsample方法考察不同投资组合保险策略绩效之间的关系，表明投资组合保险策略随机占优于其他策略，OBPI策略优于CPP策略，CPPI策略优于TIPP策略；同时本文考察了以沪深300、上证50、上证180等不同指数作为风险资产的投资组合保险策略绩效的差异，实证表明沪深300作为风险资产的投资组合保险策略要优于其他指数作为风险资产的投资组合保险策略。

世界各国政府积极地推行的通胀目标政策，导致了当前的流动性泛滥，价格的发散以及全球性通胀，利率的长期偏离又引致投机的盛行，低效的投资和资产泡沫的膨胀，当这种短期性增长不可持续时，经济将以危机收场，最终恢复至本来位置。本文在财政和货币政策协作机制下，建立了具有非零通胀稳态的粘性价格和粘性工资的新凯恩斯模型，研究了财政支配机制中的最优通货膨胀，分析表明：财政和货币政策共同决定通胀，财政支配机制中的最优通货膨胀正向偏离稳态，而这种偏离是以财政对因通胀产生的资源配置扭曲性影响的效用补偿为前提的，即当财政对社会存在效用的补偿时，才具有正向偏离稳态的最优通胀，这是“适度的通胀有益于经济增长”的唯一理由。同时，最优的实际利率大于零，且最优的名义利率为通胀与实际资本回报的比例之和，财政的补偿性效应的存在并不对利率和通胀政策产生实质性影响，即财政补偿效用和实际利率是对通胀所产生的资源配置的扭曲性影响的对价补偿。分析同时还表明财政和货币协作是治理通胀和平抑波动有效政策方式，通胀和利率相当于一个硬币的两面，两者长期的偏离不导致社会福利恶化的唯一可能性条件是财政对社会的效用补偿。
