This study derives an extension of the Black-Scholes model and recovers the real drift of binary call options from their market prices. For space-dependent real drift, we obtain stable linearization and an integral equation. We also find that using market prices of options with different strike prices enables us to identify the term structure of the real drift. Results demonstrate that our new approach can confirm the existence of arbitrage opportunities in a binary option transaction.展开更多

However, with respect to foreign banks, capital management of commercial banks is only just beginning. Especially after the proposed Basel, how to adjust the capital assets of commercial banks is to enable them to comply with Basel II requirements, ensuring stability and development of the banking sector is the China Banking Regulatory Commission and the commercial banks. So, how intensive management can reduce capital occupation to increase the capital adequacy ratio is an important part of the commercial banks that must be studied.展开更多
