In the continuous-time finance literature, it is claimed that the expected rate of return of underlying asset does not affect the option pricing model. This paper has shown that with no arbitrage, i.e., under the Arbitrage (Gordan) theorem, different underlying asset price processes used in the...

This paper has proposed new option Greeks and new upper and lower bounds for European and American options.

Behavioral economics, notably developed by Daniel Kahneman, Amos Tversky and Richard Thaler, has found consistent and pervasive anomalies in common people’s daily behaviors. This paper has employed the concepts in traditional economics (e.g., choice, relative price, and opportunity cost) to...

This paper has used the Arbitrage Theorem under binomial case to show that in a complete market with no transaction costs and no arbitrage, for any asset, the current spot price is a function of the risk-free interest rate, the future possible prices and their probabilities. These probabilities...
