Cubic Spline Method for a Generalized Black‐Scholes Equation [PDF]

Mathematical Problems in Engineering, 2014
We develop a numerical method based on cubic polynomial spline approximations to solve a a generalized Black‐Scholes equation. We apply the implicit Euler method for the time discretization and a cubic polynomial spline method for the spatial discretization.

Why do firms strategically delay payments of corporate loans?

Journal of Financial Research, EarlyView.
Abstract Firms may prefer to delay some loan payments while continuing to service others because of lender and loan characteristics. I explore the impact of bank‐level and bank‐firm‐level indicators on the strategic delay behaviors of nonfinancial corporations. Three factors play a key role in their strategic delay decisions.

A Contour Integral Method for the Black–Scholes and Heston Equations [PDF]

SIAM Journal on Scientific Computing, 2011
A contour integral method recently proposed by Weideman [IMA J. Numer. Anal., 30 (2010), pp. 334-350] for integrating semidiscrete advection-diffusion PDEs is improved and extended for application to some of the important equations of mathematical finance.

Segment information disclosure and trade credit

Journal of Financial Research, EarlyView.
Abstract We examine the effect of mandatory segment disclosure on trade credit financing. Segment disclosure reduces the information advantage of suppliers relative to investors in evaluating firm default risk, reducing firms' reliance on trade credit. Exploiting the adoption of SFAS 131 as a shock to segment disclosure, we find that segment disclosure

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 ...

Revisiting the Black-Scholes equation [PDF]

, 1998
In common finance literature, Black-Scholes partial differential equation of option pricing is usually derived with no-arbitrage principle. Considering an asset market, Merton applied the Hamilton-Jacobi-Bellman techniques of his continuous-time consumption-portfolio problem, deriving general equilibrium relationships among the securities in the asset ...

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 ...

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 ...

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.
