This paper derives a simple square root option pricing model (SSROPM) using a general equilibrium approach in an economy where the representative agent has a generalized logarithmic utility function. Our option pricing formulae, like the Black-Scholes model, do not depend on the preference...

This paper generalizes the seminal Cox-Ross-Rubinstein (1979) binomial option pricing model to all members of the class of transformed-binomial pricing processes. Our investigation addresses issues related with asset pricing modeling, hedging strategies, and option pricing. We derive explicit...

This paper derives the pricing bounds of a currency cross-rate option using the option prices of two related dollar rates via a copula theory and presents the analytical properties of the bounds under the Gaussian framework. Our option pricing bounds are useful, because (1) they are general in...

We investigate the preference and distribution restrictions that underlie explicit risk-neutral option valuation equations. We establish new sufficient conditions in terms of utility functions and joint distributions of assets' payoffs and state variables for these models to hold in equilibrium...

This paper extends the jump-diffusion option pricing model of Merton (1976) and the displaced diffusion option pricing model of Rubinstein (1983) to price options on stock indices. First, we provide a theory showing that the stock index value has a positive threshold or positive lower bound if...
