Parenthood and CEO Responses to Media Criticism on Pay

Journal of Management Studies, EarlyView.
Abstract Research on media coverage of controversial corporate practices typically suggests firms respond instrumentally to mitigate stakeholder reactions. However, we argue that CEOs' moral concerns can sometimes override strategic considerations, because media criticism may expose them to scrutiny from personally valued audiences – for instance ...

On properties of solutions to Black–Scholes–Barenblatt equations

Advances in Difference Equations, 2019
This paper is concerned with the Black–Scholes–Barenblatt equation ∂tu+r(x∂xu−u)+G(x2∂xxu)=0 $\partial _{t}u+r(x\partial _{x}u-u)+G(x^{2}\partial _{xx}u)=0$, where G(α)=12(σ‾2−σ_2)|α|+12(σ‾2+σ_2)α $G(\alpha )=\frac{1}{2}(\overline{\sigma}^{2}-\underline{\

Measure‐valued processes for energy markets

Mathematical Finance, Volume 35, Issue 2, Page 520-566, April 2025.
Abstract We introduce a framework that allows to employ (non‐negative) measure‐valued processes for energy market modeling, in particular for electricity and gas futures. Interpreting the process' spatial structure as time to maturity, we show how the Heath–Jarrow–Morton approach can be translated to this framework, thus guaranteeing arbitrage free ...

Perpetual Futures Pricing

Mathematical Finance, EarlyView.
ABSTRACT Perpetual futures are contracts without expiration date in which the anchoring of the futures price to the spot price is ensured by periodic funding payments from long to short. We derive explicit expressions for the no‐arbitrage price of various perpetual contracts, including linear, inverse, and quantos futures in both discrete and ...

Option Pricing in a Fractional Brownian Motion Environment [PDF]

The purpose of this paper is to obtain a fractional Black-Scholes formula for the price of an option for every t in [0,T], a fractional Black-Scholes equation and a risk-neutral valuation theorem if the underlying is driven by a fractional Brownian ...

Reinforcement Learning for Jump‐Diffusions, With Financial Applications

Mathematical Finance, EarlyView.
ABSTRACT We study continuous‐time reinforcement learning (RL) for stochastic control in which system dynamics are governed by jump‐diffusion processes. We formulate an entropy‐regularized exploratory control problem with stochastic policies to capture the exploration–exploitation balance essential for RL.

Robust Mean–Variance Portfolio Optimization: Mean–Variance–Variance Criterion Versus Mean–Variance–Standard Deviation Criterion

Mathematical Finance, EarlyView.
ABSTRACT We study a dynamic portfolio optimization problem under the mean–variance–variance (M‐V‐V) criterion proposed by Maccheroni et al. It is an analogue of the Arrow–Pratt approximation to the well‐known smooth ambiguity model. Under the standard Black–Scholes framework, we derive fully explicit equilibrium investment strategies in which a DM's ...

Adaptive Wavelet Precise Integration Method for Nonlinear Black-Scholes Model Based on Variational Iteration Method

Abstract and Applied Analysis, 2013
An adaptive wavelet precise integration method (WPIM) based on the variational iteration method (VIM) for Black-Scholes model is proposed. Black-Scholes model is a very useful tool on pricing options.

Improving Implied Volatility Forecasts for American Options Using Neural Networks

Journal of Futures Markets, Volume 46, Issue 6, Page 1137-1153, June 2026.
ABSTRACT This paper explores the application of neural networks to improve pricing of American options. Focusing on both American and European options on the S&P 100 index from January 2016 to August 2023, we integrate neural networks to model the difference between market‐implied and model‐implied volatilities derived from the Black‐Scholes and Heston
