Fractional constant elasticity of variance model
, 2006 This paper develops a European option pricing formula for fractional market models. Although there exist option pricing results for a fractional Black-Scholes model, they are established without accounting for stochastic volatility.

The Futility of Utility: how market dynamics marginalize Adam Smith [PDF]
, 1999 Econometrics is based on the nonempiric notion of utility. Prices, dynamics, and market equilibria are supposed to be derived from utility. Utility is usually treated by economists as a price potential, other times utility rates are treated as ...

Fractional Quantum Field Theory, Path Integral, and Stochastic Differential Equation for Strongly Interacting Many-Particle Systems [PDF]
, 2012 While free and weakly interacting particles are well described by a a second-quantized nonlinear Schr\"odinger field, or relativistic versions of it, the fields of strongly interacting particles are governed by effective actions, whose quadratic terms ...

The Role of Index Fund Ownership in the Era of Say‐on‐Pay
Financial Management, EarlyView.ABSTRACT We examine whether and how index funds influence executive compensation in the post‐Say‐on‐Pay era. Using the annual reconstitution of the Russell indexes as a source of exogenous variation in index fund ownership, we document a causal effect of index ownership on CEO pay structure.

Qualitative financial modelling in fractal dimensions
Financial InnovationThe Black–Scholes equation is one of the most important partial differential equations governing the value of financial derivatives in financial markets. The Black–Scholes model for pricing stock options has been applied to various payoff structures, and

Numerical Analysis of the Time Fractional Black-Scholes Equation [PDF]
, 2016 时间分数阶Black-Scholes方程在期权定价中有着日益广泛的应用。本文旨在研究该方程的数值解法，构造和分析了两个有效算法。第一个算法结合了时间方向的有限差分和空间方向的谱方法；第二个方法则基于时空Galerkin谱方法。通过引入恰当的Sobolev空间，我们构建了时空变分问题，证明了时空弱问题的适定性。在算法分析方面，我们首先给出两种方法的最优误差估计。然后讨论算法实现技巧，通过选取适当的基函数导出离散问题的线性系统。最后给出一些数值例子验证理论结果。The time fractional ...

Inscribing Impact: Measurement Practices in the Making of Moral Markets
Journal of Management Studies, EarlyView.Abstract Moral markets, designed to generate positive impact on pressing social and environmental challenges, are transforming traditional market practices by including more than economic considerations in their operations. The importance of these markets continues to grow as investors, regulators, and consumers increasingly put pressure on companies ...
