American Index Put Options Early Exercise Premium Estimation, Ako Doffou
WCBT Faculty Publications
"This paper examines empirically the value of early exercise by testing the ability of two American put valuation models to predict the early exercise premium for the S&P 100 American put options. An accuracy test and a quality test are performed on (1) the MacMillan (1986) & Barone-Adesi and Whaley (1987) model, and (2) the Carr, Jarrow and Myneni(1992) model. The test results show that early exercise premium is significant regardless of moneyness. Moreover, consistent with the theory, the value of early exercise is significantly negatively related to moneyness and interest rates and significantly positively related to time to maturity …

Accounting is a manifestation of several important environmental factors within a country, including economic, educational and political, and, as such, is evolutionary in accordance with those changing social structures. In today‟s ever expanding global economy, the understanding of international aspects of accounting is critical to understanding world events and the way in which they affect our lives.

Periodically Collapsing Bubbles In The Asian Emerging Stock Markets, Ako Doffou
Periodically Collapsing Bubbles In The Asian Emerging Stock Markets, Ako Doffou
WCBT Faculty Publications
This paper investigates empirically the existence of periodically collapsing bubbles in the Asian emerging stock markets using the Enders-Siklos (2001) momentum threshold autoregressive model. As explained in Bohl (2003), this non-linear time series technique can be used to analyze bubble driven run-ups in stock prices followed by a crash in a non- cointegration framework with asymmetric adjustment. This technique offers a more potent insight in the stock prices behavior than can possibly be obtained using conventional non-cointegration tests. The empirical findings for ten Asian emerging stock markets from 1993 to 2005 refute the bubble hypothesis.
