WORLDSIM simulates country futures to 2050. You set the scenario, the engine runs thousands of paths, and you see the full distribution of plausible outcomes.
Energy costs, inflation, household burden, and industrial competitiveness across 195 countries.
Housing affordability, sovereign debt sustainability, and fiscal pressure dynamics.
Real wages, rent affordability, cost of living, and migration flows.
Migration outflows, fiscal revenue collapse, crime rates, and demographic decline.
You can run any of these in WorldSim today - 10,000 trajectories, 30+ KPIs, 195 countries.
A simulation engine for institutions that need full probability distributions, not point forecasts.
Run Better, Average, and Shock scenarios across 30+ KPIs. Every output is a probability distribution, not a point forecast.
100+ active rules enforce causal relationships between variables. GDP shocks propagate to unemployment, migration, and fiscal pressure.
10,000+ simulated paths per scenario using two-piece lognormal and bounded-logit draws. Full P10/P50/P90 quantile outputs.
Translate macro outcomes into personal impacts: income projections, housing affordability, and job risk based on age, industry, and salary.
Compare any two scenarios side by side and validate simulation accuracy against historical actuals using backtesting metrics across all KPIs.
Each simulation pass applies seven sequential layers, producing internally consistent probabilistic futures.
Ingest from OECD, World Bank, Eurostat, and IMF. Normalise into canonical country-metric observations.
Generate P10/P50/P90 forecast distributions using damped trend models and sigma bands for each variable.
Apply user-defined scenario overlays (Better Than Expected, As Planned, or Shock) with configurable sigma shifts and persistence for all KPIs.
100+ structural rules. When GDP drops, the impact ripples through unemployment, migration, fiscal pressure, and energy systems automatically.
Tilt-activated. User biases propagate to co-moving KPIs via per-country Spearman correlations plus 160+ academic theory overrides, applied as a mean-shift before sampling. Marginal-rule suppression prevents double-counting against coupling rules.
10,000+ stochastic draws per scenario path using two-piece lognormal distributions. Produces full quantile fan charts.
Translate macro country futures into personal outcomes (income, housing burden, job risk) based on age, industry, and salary profile.
Every run produces a full institutional risk and rating layer, from the probability of adverse outcomes to an implied structural rating and composite scores benchmarked against the world.
Likelihood of adverse outcomes. The share of simulated paths that hit recession, stagflation, or fiscal, sovereign, energy and housing stress by each horizon.
Fiscal and debt sustainability. The interest-growth differential, the debt-stabilising primary balance, gross financing needs, and the S2 ageing gap.
Implied structural rating. A sovereign-rating equivalent scored on every path, giving a full rating distribution and the probability of investment grade, not a single notch.
Composite structural scores. Seven scores from 0 to 100, from economic resilience to fiscal vulnerability and competitiveness, ranked against the world's economies.
