Revolutionizing Option Pricing: Generalized Black-Scholes with Dynamic Parameters and Quantum Analogies
This analysis delves into a groundbreaking extension of the Black-Scholes model, incorporating time-varying power-law parameters and establishing a profound analogy with the Schrödinger equation featuring position-dependent mass. This advancement addresses critical limitations of traditional models, offering superior accuracy and deeper insights into market dynamics, particularly during periods of high volatility and structural shifts. It proposes a novel quantum-inspired framework to enhance financial risk management and derivative pricing.
Executive Impact Summary
The research introduces a generalized Black-Scholes model that moves beyond static parameters by integrating time-dependent volatility, interest rates, and dividend yields governed by power-law dynamics. This enhanced model, validated through analytical solutions and numerical simulations, provides a more realistic representation of financial markets. Crucially, the study demonstrates a direct equivalence between this generalized Black-Scholes equation and a Schrödinger equation with position-dependent mass, offering a quantum mechanics-inspired approach to financial modeling. This framework allows for a more nuanced understanding of market fluctuations, risk transmission, and option pricing, especially for complex derivatives. The implications extend to improved forecasting, more robust risk management strategies, and the potential for quantum computing applications in finance, bridging theoretical rigor with practical applicability.

The methodology involves generalizing the Black-Scholes Partial Differential Equation (BSE) by allowing parameters like volatility, risk-free interest rates, and dividend yields to vary over time according to power-law functions. This transformation leads to new analytical solutions obtained via variable transformations and Laplace transforms. Furthermore, the model establishes a compelling analogy with the Schrödinger equation, particularly one characterized by a position-dependent mass, allowing for the application of quantum mechanics principles to financial modeling. This interdisciplinary approach enhances the framework's ability to capture complex market dynamics and provides a richer theoretical foundation for option pricing and risk management.

Schrödinger Equation with PDM
By transforming the generalized Black-Scholes equation, the research reveals its equivalence to a Schrödinger equation where the 'mass' of the underlying asset (e.g., stock) is position-dependent. This PDM formalism is highly relevant in quantum mechanics and materials science, now offering a novel way to interpret and model financial phenomena and market 'gravity'.
