Wealth Taxation as a Drift Modification: A Fokker-Planck Approach to Tax Neutrality
Anders G Frøseth
The paper recasts a neutral wealth tax model as a stochastic process, showing that a proportional wealth tax acts as a uniform shift in the drift term of a Fokker-Planck equation g…
Heterogeneous Returns and Wealth Tax Neutrality: A Fokker-Planck Framework
Anders G Frøseth
We extend the Fokker-Planck framework of Froseth (2026, arXiv:2603.05283) to populations of investors with heterogeneous, persistent return-generating ability. When the drift coeff…
Spectral Portfolio Theory: From SGD Weight Matrices to Wealth Dynamics
Anders G Frøseth
We develop spectral portfolio theory by establishing a direct identification: neural network weight matrices trained on stochastic processes are portfolio allocation matrices, and…
From Gravity to Confinement: Wealth Redistribution as Optimal Drift Design in the Fokker-Planck Framework
Anders G Frøseth
A proportional wealth tax acts as a uniform gravitational field on the wealth distribution: it shifts the drift of the Fokker-Planck equation without altering the diffusion, preser…
Tax Migration as Social Contagion: A Tipping-Point Model with Application to the Scandinavian Wealth Tax Debate
Anders G Frøseth
Blandhol (2025) estimates that wealth-tax-induced emigration from Norway reduces long-run GDP by 1.3%. Dansk Industri scaled this figure to argue that a Danish wealth tax would cos…
A Spectral Generalisation of the Variance Ratio: Eigenstructure of Long-Horizon Portfolio Covariance and a Multi-Memory Factor Model of U.S. Equity Returns
Anders G Frøseth
We propose a multivariate generalisation of the Lo-MacKinlay (1988) variance ratio that decomposes long-horizon equity-return dynamics into separate return-channel and volatility-c…
