Source & Grounding

Simulated in response to Financial Times reporting on accelerated departures of high-profile London asset managers and private equity executives following fiscal policy shifts under the UK Labour administration. Model incorporates behavioral elasticity studies from the London School of Economics (LSE) Wealth Commission and Centre for the Analysis of Taxation (CenTax).

Tax Elasticity Model Assumptions

Gross calculations assume 145,000 qualifying individuals with qualifying worldwide net assets above £10m. Capital flight loss models loss of top-tier PAYE, dividend taxes, capital gains, stamp duty on prime central London property, and consumption taxes.
