Option Pricing in a Fractional Brownian Motion Environment [PDF]

open access: yes
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 ...

Market Consistent Valuation for Bitcoin Options With Long Memory in Conditional Volatility and Conditional Non‐Normality

open access: yesJournal of Futures Markets, Volume 45, Issue 8, Page 917-945, August 2025.
ABSTRACT This paper investigates the economic consequences for Bitcoin options' prices of a long memory in conditional volatility and conditional non‐normality of Bitcoin returns. The arbitrage‐free prices of Bitcoin options are determined by market consistent valuation and the conditional Esscher transform. Monte Carlo estimates for option prices from

A Novel Fourth-Order Finite Difference Scheme for European Option Pricing in the Time-Fractional Black–Scholes Model

open access: yesMathematics
This paper addresses the valuation of European options, which involves the complex and unpredictable dynamics of fractal market fluctuations. These are modeled using the α-order time-fractional Black–Scholes equation, where the Caputo fractional ...

A Framework for Derivative Pricing in the Fractional Black-Scholes Market [PDF]

open access: yes
The aim of this paper is to develop a framework for evaluating derivatives if the underlying of the derivative contract is supposed to be driven by a fractional Brownian motion with Hurst parameter greater than 0.5.

Number Two Executives: Bottom‐Up Monitoring

open access: yesJournal of Business Finance &Accounting, Volume 52, Issue 4, Page 2037-2061, August 2025.
ABSTRACT This article empirically examines the role of a firm's second‐in‐command in monitoring the chief executive officer (CEO) from the bottom up to mitigate agency problems. Although CEOs have long been the focus, little research has addressed No. 2 executive. This study provides a comprehensive understanding of these top executives and their roles

Precise asymptotics: robust stochastic volatility models

open access: yes, 2018
We present a new methodology to analyze large classes of (classical and rough) stochastic volatility models, with special regard to short-time and small noise formulae for option prices.

Impacts of Permafrost Degradation on N2O Emissions From Natural Terrestrial Ecosystems in Northern High Latitudes: A Process‐Based Biogeochemistry Model Analysis

open access: yesGlobal Biogeochemical Cycles, Volume 39, Issue 4, April 2025.
Abstract Nitrous oxide (N2O) is a potent greenhouse gas with its radiative forcing 265–298 times stronger than that of carbon dioxide (CO2). Recent field studies show N2O emissions from northern high latitude (north of 45°N) ecosystems have increased due to warming.
