Purpose – The paper aims to clarify the relationship between earnings management and the sale of long-lived assets and investments for firms listed in Taiwan. In addition, it suggests several interesting issues for further studies by proposing that positive earnings are one of the necessary...

By extending the results of previous literature, this study contributes to propose a fuzzy stochastic model for valuing the option to invest in an irreversible investment. The proposed model can provide reasonable ranges of option value, which investors can use to either exercise the option to...

This paper employs a real options approach to analyze optimal investment decisions. When investment projects have the characteristics of irreversibility, uncertainty and the option to wait or exit, the traditional net present value (NPV) method would underestimate the value of investment, since...

This study presents a novel catastrophe option pricing model that considers counterparty risk. Asset prices are modeled through a jump-diffusion process which is correlated to counterparty loss process and collateral assets. Because of the long term of catastrophe options, this study also...

This paper introduces the autocorrelation effect of assets’ returns into the valuation model of reset options. The MA(q) process, which is an extension of MA(1) process noted by Liao and Chen (2006), is applied to the valuation of reset options in this paper. Due to the impact of...

This article investigates the feasibility of using range-based estimators to evaluate and improve Generalized Autoregressive Conditional Heteroscedasticity (GARCH)-based volatility forecasts due to their computational simplicity and readily availability. The empirical results show that daily...

This study employs single and multiple variance ratio tests to reexamine the weak-form efficient market hypothesis (EMH) of A- and B-shares on the Shanghai and Shenzhen exchanges in Chinese stock market. The study also examines the influence of the release of investment restriction of B-share...
