The paper reviews the option pricing model constructs of Bachelier and Black-Scholes Merton, concluding the latter model approximates the former. The paper demonstrates that certain critiques of the Bachelier model outlined in the 1960s and 1970s are not sound; and Bachelier's model can be...

The Black-Scholes framework implies a constant volatility across term and strike, and a lognormal distribution for underlying asset prices. However, it is known that empirical data violates this assumption. In this report we describe, motivate and apply a model-independent,...

The purpose of this paper is to develop a new non-parametric method to price options based on normalized Multipoint Padé Approximants. Following the seminal paper of Padé (1892), we propose to approximate the risk-neutral distribution by a rational function of polynomials that can accommodate...

In an equilibrium framework the dynamics of the aggregate dividend are taken as given and the volatility of the wealth portfolio is determined by the prices of risk in the model. Since option prices depend strongly on volatility they are very informative about these risk prices. We use this...

We show that a dynamic model of investment and capital structure choices, where the firm faces real and financial frictions, can generate option prices and implied volatilities that are in line with those of the average optionable stock. As the balance between the fundamental economic forces...

The article describes a global and arbitrage-free parametrization of the eSSVI surfaces introduced by Hendriks and Martini in 2019. A robust calibration of such surfaces has already been proposed by the quantitative research team at Zeliade in 2019, but it is sequential in expiries and lacks of...

If a discretely formulated asset pricing model rivals efficacy of the Black and Scholes (1973) option pricing model, with canonical properties of option prices satisfied, rather counterfactually it spans a support space for call option prices that is continuous. Absent any directness of modeling...

American options are actively traded worldwide on exchanges, thus making their accurate and efficient pricing an important problem. As most financial markets exhibit randomly varying volatility, in this paper we introduce an approximation of American option price under stochastic volatility...

In this paper, I have used simple arbitrage argument to derive a dozen of model-free option price properties. In addition to deriving the Greeks under the model-free framework, the results show that first, in contrast to the traditional view, a European call (put) option for a...
