The Analytical Solution for the Black-Scholes Equation with Two Assets in the Liouville-Caputo Fractional Derivative Sense

Mathematics, 2018
It is well known that the Black-Scholes model is used to establish the behavior of the option pricing in the financial market. In this paper, we propose the modified version of Black-Scholes model with two assets based on the Liouville-Caputo fractional ...

Contingent capital: A tale of two valuations

Journal of Risk and Insurance, EarlyView.
Abstract This study investigates the valuation gap between buyers and sellers of insurers' contingent capital, driven by asymmetric exposures to tax benefits, capital injections, and bankruptcy costs. We develop a novel Twin‐Tree Model with Jumps (TTMJ) that models the insurer's asset value dynamics by incorporating catastrophe risk, insolvency risk ...

Why Have CEO Pay Levels Become Less Diverse?

The Journal of Finance, Volume 81, Issue 4, Page 1893-1950, August 2026.
ABSTRACT This paper documents a new stylized fact: the cross‐sectional variation in CEO pay levels has declined precipitously in recent years. We offer one explanation for this decline, namely, firms are increasingly benchmarking CEO compensation to industry peers closest in size, thereby creating pay clusters.

The Debt‐Equity Spread

The Journal of Finance, Volume 81, Issue 4, Page 2005-2062, August 2026.
ABSTRACT We propose a measure of the valuation gap between debt and equity—debt‐equity spread (DES)—based on the difference between actual and equity‐implied credit spreads. DES predicts cross‐sectional stock and bond returns in opposite directions.

An adaptive moving mesh method for a time-fractional Black–Scholes equation

Advances in Difference Equations, 2019
In this paper we study the numerical method for a time-fractional Black–Scholes equation, which is used for option pricing. The solution of the fractional-order differential equation may be singular near certain domain boundaries, which leads to ...

Investigation of Higher Order Localized Approximations for a Fractional Pricing Model in Finance

Mathematics, 2023
In this work, by considering spatial uniform meshes and stencils having five adjacent discretization nodes, we furnish a numerical scheme to solve the time-fractional Black–Scholes (partial differential equation) PDE to price financial options under the ...

Revising the Magnitude and Trends of the Global Methane Soil Sink With Process‐Based, Machine‐Learning, and Atmospheric Inversion Modeling Approaches

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 7, July 2026.
Abstract Methane (CH4) oxidation by microbes is the largest biological sink of global methane, yet its magnitude and long‐term variability remain uncertain. Here, we combined process‐based (PB), machine‐learning (ML), and atmospheric inversion approaches to evaluate the global methane soil sinks and its implication for the atmospheric CH4 budget in ...
