Qualitative financial modelling in fractal dimensions
Financial InnovationThe Black–Scholes equation is one of the most important partial differential equations governing the value of financial derivatives in financial markets. The Black–Scholes model for pricing stock options has been applied to various payoff structures, and

Numerical Analysis of the Time Fractional Black-Scholes Equation [PDF]
, 2016 时间分数阶Black-Scholes方程在期权定价中有着日益广泛的应用。本文旨在研究该方程的数值解法，构造和分析了两个有效算法。第一个算法结合了时间方向的有限差分和空间方向的谱方法；第二个方法则基于时空Galerkin谱方法。通过引入恰当的Sobolev空间，我们构建了时空变分问题，证明了时空弱问题的适定性。在算法分析方面，我们首先给出两种方法的最优误差估计。然后讨论算法实现技巧，通过选取适当的基函数导出离散问题的线性系统。最后给出一些数值例子验证理论结果。The time fractional ...

The Role of Index Fund Ownership in the Era of Say‐on‐Pay
Financial Management, EarlyView.ABSTRACT We examine whether and how index funds influence executive compensation in the post‐Say‐on‐Pay era. Using the annual reconstitution of the Russell indexes as a source of exogenous variation in index fund ownership, we document a causal effect of index ownership on CEO pay structure.

Why Have CEO Pay Levels Become Less Diverse?
The Journal of Finance, EarlyView.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.

Inscribing Impact: Measurement Practices in the Making of Moral Markets
Journal of Management Studies, Volume 63, Issue 3, Page 1229-1263, May 2026.Abstract Moral markets, designed to generate positive impact on pressing social and environmental challenges, are transforming traditional market practices by including more than economic considerations in their operations. The importance of these markets continues to grow as investors, regulators, and consumers increasingly put pressure on companies ...

Global Natural Soil N2O Emissions: An Analysis With a Global Biogeochemistry Model From 1990 to 2023
Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.Abstract Atmospheric N2O, the dominant ozone‐depleting substance and a potent greenhouse gas, has risen notably over recent decades. Using a process‐based model, we simulated the sensitivity of N2O emissions from undisturbed natural soils to the representation of historical land‐cover change from 1990 to 2023 by factoring the effects of atmospheric ...

Journal of Ecology, Volume 114, Issue 4, April 2026.We compared soil organic carbon (SOC) across six savanna–forest boundaries in South Africa. Surprisingly, savanna and forest soils contained comparable SOC stocks. While vegetation change shifted the carbon source from C4‐grasses to C3‐trees, total carbon storage was driven by local soil texture (clay/silt), proving that increasing tree cover does not ...

Race‐related research in economics
Economica, Volume 93, Issue 370, Page 403-438, April 2026.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.
