China has taken important steps to reform its economy and capital markets in the past 20 years.

In practice, it is observable that firms tend to smooth periodical earnings because periodical earnings are considered by capital markets as a proxy for firms' success, and therefore, are often operationalized by the respective compensation plans for managers. Considering financial hedging...

We examine co-movements of nine Asian equity markets with both the US and Japan with special interest in distinguishing co-movements during periods of positive returns from those during periods of negative returns. A discrete asymmetric piecewise linear conditional mean returns specification is...

This paper investigates the monthly initial return and its conditional return volatility for Chinese IPOs. We find that the mean initial return (IR) and cross-sectional return volatility are highly auto- and cross-correlated, and time-varying. We propose a system of two simultaneous equations: a...

This study attempts to address two research questions on the idiosyncratic return volatility and stock price informativeness. First, whether idiosyncratic return volatility is a valid proxy for stock price informativeness in emerging markets, and if it is, whether there exists a monotonic...

Prior research has shown that credit downgrades affect firm's capital structure decision. However, after adjusting for biases associated with the use of market debt ratio and after controlling for simultaneity between credit ratings and leverage, we find that rating upgrades also play a role in...

We investigate a portfolio optimization problem under the threat of a market crash, where the interest rate of the bond is modeled as a Vasicek process, which is correlated with the stock price process. We adopt a non-probabilistic worst-case approach for the height and time of the market crash....

The uncertainty that accompanies the modern capital market leads to change and to create various forms of risk management. These changes indicate the development of countries' financial systems, but also carry risks, resulting in losses in the global economy. The last crises forced to the...
