This study examines relation between financial development and the cost of equity capital and finds the following main results: (1) stock market development in general reduces cost of equity, consistent with its role in liquidity provision, information asymmetry reduction, and risk diversification helping to reduce systemic risk; (2) banking development only weakly decreases the cost of equity, consistent with the pervasive state-ownership in large banks constraining their efficiency. Further analysis reveals that the relation between stock market development and cost of equity is more pronounced in large firms and in firms with lower growth potentials, suggesting that stock market development fails to support small and/or growth firms. Moreover, the relation is more pronounced in region with low accounting quality, weak law enforcement, or lower market integration, and in period prior to split share structure reform. The evidence suggests that stock market developments and other institutional arrangements substitute each other in reducing cost of equity. This study contributes to literatures on financial development and cost of equity, and also holds immediate policy implications.

Until recently, Chinese companies publicly listed in domestic stock exchanges had two classes of stock: tradable and non-tradable shares. These two classes of stock had the same voting, cash flow, and all other legal rights except that non-tradable shares cannot be transferred at the open markets. From 2005 to mid-2007, Chinese government completed the ownership reform, so-called the Split Share Structure Reform (SSSR), to convert all non-tradable shares into tradable shares. Under this reform process, the holders of non-tradable shares had to negotiate with those of tradable shares to determine how much liquidity premium, or the compensation ratio, non-tradable shareholders have to pay to tradable shareholders in order to obtain the liquidity right. This paper starts with a theoretical model to identify the fundamental factors, including price discount before and after the SSSR reform, the percentage of non-tradable shares in total shares, the volatility of tradable share price, and the lockup period, that should determine the compensation ratio. We show that those factors except price discount before the reform are statistically significant in determining the compensation ratio proposed by non-tradable shareholders. We further show that the agency problems also reveal themselves in the compensation ratios. Specifically, when a firm is controlled by a governmental agency, the compensation is higher. However, the compensation is lower when more concentrated in the top ten holders, especially when shares are held by mutual funds. Thus, the evidence is consistent with the notion that the agency problem exists in China’s fund managers. Finally, we show that the existence of agency problems also reduce the importance of fundamental factors in determining the compensation ratios.

A fundamental question in finance is whether and how removing market frictions is associated with efficiency gains. We study this question using share issue privatization in China that took place through the split share structure reform. Prior to the reform, domestic A-shares were divided into tradable and non-tradable shares with identical cash flow and voting rights. Under the reform, holders of the non-tradable shares negotiated a compensation plan with holders of the tradable shares in order to make their shares tradable. We hypothesize that efficiency gains in terms of better risk sharing play an important role in the determination of compensation. We show that the size of compensation is positively associated with both the gain in risk sharing and the price impact of more shares coming to the market after the reform, and is negatively associated with the bargaining power of holders of non-tradable shares and firm performance. Our study highlights the role of risk sharing in China’s share issue privatization.

China launched her warrant market in August 2005 in the split share structure reform of listed companies. As up to now, equity trading on margin and short-sale of any form are still prohibited in China. This warrant market enables investors to trade on information that otherwise might be prohibitively expensive to trade on. The Chinese warrant market created top trading volume and turnover with only a handful of different warrants traded. This paper first studies the Chinese warrant market. Empirical evidence shows that the market prices of warrants are much higher systematically than the Black-Scholes prices with historical volatility. Moreover, the paper documents ample evidence that the one-dimensional diffusion model does not apply well in the Chinese warrant market. The prices of a warrant and its underlying asset do not support the monotonicity, perfect correlation and option redundancy properties. The paper also studies the cumulated gains of a delta-hedged warrant portfolio. In the Chinese warrant market, the cumulated delta-hedged gains for almost all expired warrants are negative. The negative gains are mainly driven by the volatility risk, and the trading values of the warrants for puts and the market risk for calls. The investors are trading some other risks in addition to the underlying risk.

Trading constraints with unspecified constraint horizon are imposed on the shares held by the state in the IPO of each listed firm in China Stock Market. In 2005, a so-called Split Share Structure Reform (also known as Division Reform) was launched in which the holders of restricted shares give up a proportion of their shares to purchase the right to terminate the trading constraint. From the size of the compensation, we infer the value of restricted shares and find that their price discounts are negatively affected by the restriction looseness captured by our proposed new multi-dimensional measure and positively affected by the bargaining power of the holders of freely-traded shares.

A fundamental question in economics and finance is whether and how removing barriers is associated with efficiency gains. We study this question using share issue privatization in China that took place through the split share structure reform as our experimental setting. Prior to the reform, domestic Ashares are divided into tradable and non-tradable shares with identical cash flow and voting rights. Under the reform, non-tradable share holders negotiate a compensation plan with tradable share holders in order to make their shares tradable. We develop a general equilibrium model to help understand the determinants of compensation and the source of gains in the process of privatization. Our key predictions are: a) there is compensation made by the non-tradable share holders to the tradable share holders if and only if the bargaining power of the former is weaker than the bargaining power of the latter; and b) the size of the compensation is decreasing in firm performance. Our second prediction contradicts conventional wisdom that fails to account for improved risk sharing after the reform. Our empirical results are broadly consistent with our model’s predictions. We conclude that better risk sharing is an important consideration in China’s share issue privatization.
