Policy modelling

Simulation models with explicit assumptions, welfare arithmetic and audit trails, covering alcohol minimum unit pricing, sugar taxation and cannabis policy.

Why Our Models Are Different

BYT-WYZE builds audited, Green Book–compliant policy engines for alcohol MUP appraisals, cannabis excise simulation, and interactive strategy games. Every model is calibrated to local data, penny-precise, and fully transparent.

Interactive simulations grounded in real-world data and rigorous economic methodology

Evidence-based alcohol policy appraisal for Portsmouth, 48 locally calibrated parameters, Holmes 2014 elasticity matrices, penny-precise accounting closure, and full HM Treasury Green Book 2024 compliance. Five interactive policy levers with real-time 20-year projections.

Treasury-safe Social Cost-Benefit Analysis for sugar tax evaluation. Monte Carlo simulation, QALY valuation, Harberger welfare accounting, and full Green Book compliance with 20-year appraisal horizon.

Alcohol MUP & Cannabis Excise simulation with 10-year NPV projections across four welfare channels. Adjust parameters in real-time, Payer EV, Treasury Revenue, Producer Surplus, and Social Externality Savings.

UK cannabis legalisation fiscal impact model with 8-group demand segmentation, 6-channel fiscal accounting, enforcement savings, psychosis risk modelling, and 10-year NPV projections.

  • Policy Modelling | Byt-Wyze
  • Penny-Precise Accounting
  • Consumer spend equals tax + legal revenue + illicit revenue with zero residual: algebraically proven, not rounded.
  • Green Book 2024 Compliant
  • STPR 3.5%, BCR, distributional welfare weights, switching values, and dual CBA perspectives: built in from the start.
  • Locally Calibrated
  • Every parameter calibrated to local primary data sources: no national defaults where local evidence exists.
  • Published Elasticities
  • Holmes 2014 Lancet matrices and peer-reviewed econometric evidence underpin all demand modelling.
  • Full Audit Trail
