Appearances of pseudo-bosons from Black-Scholes equation

open access: yes, 2016
It is a well known fact that the Black-Scholes equation admits an alternative representation as a Schr\"odinger equation expressed in terms of a non self-adjoint hamiltonian. We show how {\em pseudo-bosons}, linear or not, naturally arise in this context,

Below the leaves: Integrating above‐ and below‐ground phenology for earth‐system predictability

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Almost every aspect of biological systems has phenology—a pattern in activity or function linked to annual cycles. Most terrestrial phenology research focusses on leaves, the onset of leaf out or senescence.

Long memory stochastic volatility in option pricing

open access: yes, 2004
The aim of this paper is to present a simple stochastic model that accounts for the effects of a long-memory in volatility on option pricing. The starting point is the stochastic Black-Scholes equation involving volatility with long-range dependence.

Homotopy perturbation method for fractional black-scholes european option pricing equations using Sumudu transform [PDF]

open access: yes, 2013
The homotopy perturbation method, Sumudu transform, and He’s polynomials are combined to obtain the solution of fractional Black-Scholes equation. The fractional derivative is considered in Caputo sense.

The effect of addback statutes on CEO compensation

open access: yesAccounting &Finance, Volume 65, Issue 1, Page 793-818, March 2025.
Abstract Exploiting the adoption of addback statutes, which occurred at different times, as exogenous shocks to corporate taxable income, we examine the effect of tax policy changes on the compensation of chief executive officers (CEOs). We provide evidence that CEOs of firms headquartered in states affected by addback statutes experienced a decrease ...

Optimal hedging of Derivatives with transaction costs

open access: yes, 2005
We investigate the optimal strategy over a finite time horizon for a portfolio of stock and bond and a derivative in an multiplicative Markovian market model with transaction costs (friction).

Race‐related research in economics

open access: yesEconomica, EarlyView.
Abstract Issues of racial justice and economic inequalities between racial and ethnic groups have risen to the top of public debate. Economists' ability to contribute to these debates is based on the body of race‐related research. We study the volume and content of race‐related research in economics.

A family of positive nonstandard numerical methods with application to Black-Scholes equation [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2017
Nonstandard finite difference schemes for the Black-Scholes partial differential equation preserving the positivity property are proposed. Computationally simple schemes are derived by using a nonlocal approximation in the reaction term of the Black ...

Solution of the Fractional Black-Scholes Option Pricing Model by Finite Difference Method

open access: yesAbstract and Applied Analysis, 2013
This work deals with the put option pricing problems based on the time-fractional Black-Scholes equation, where the fractional derivative is a so-called modified Riemann-Liouville fractional derivative.

A posteriori grid method for a time-fractional Black-Scholes equation

open access: yesAIMS Mathematics, 2022
In this paper, a posteriori grid method for solving a time-fractional Black-Scholes equation governing European options is studied. The possible singularity of the exact solution complicates the construction of the discretization scheme for the time ...
