Novel ANN Method for Solving Ordinary and Time-Fractional Black–Scholes Equation
The main aim of this study is to introduce a 2-layered artificial neural network (ANN) for solving the Black–Scholes partial differential equation (PDE) of either fractional or ordinary orders.

Inscribing Impact: Measurement Practices in the Making of Moral Markets
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 ...

Hedging in fractional Black-Scholes model with transaction costs [PDF]
We consider conditional-mean hedging in a fractional Black–Scholes pricing model in the presence of proportional transaction costs. We develop an explicit formula for the conditional-mean hedging portfolio in terms of the recently discovered explicit ...

Global Natural Soil N2O Emissions: An Analysis With a Global Biogeochemistry Model From 1990 to 2023
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 ...

Option pricing under non-normal distribution in mixed of Gram-Charlier model and fractional models (A case study of Iran Stock Exchange) [PDF]
In order to reduce the risk of financial markets, various tools have emerged, and option contracts are the most common tools in this regard. The Black-Scholes model is used to price a wide range of options contracts. The basic assumption in this model is

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
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.
