Forced-saving welfare architectures (Singapore CPF since 1955, Chile AFP since 1981, Australia Superannuation Guarantee since 1992) and universal-transfer architectures (Nordic model, UK NHS) produce different profiles on two dimensions: (a) retirement-income adequacy for the median retiree, and (b) long-run fiscal sustainability as measured by projected net liabilities of the pension / welfare state over 30+ year horizons. The hypothesis is that forced-saving systems deliver comparable or better adequacy for the median saver with materially lower sovereign fiscal liability, while universal-transfer systems deliver higher redistributive effect (lower elderly poverty rates) at the cost of larger sovereign liability exposure. Both architectures face political-economy pressure to under-save or over- promise; the empirical test compares realised outcomes rather than ideal types.
Falsification criterion — what would disprove this
This hypothesis is considered falsified if:
Not supported if on pooled data (a) forced-saving systems do not show comparable-or-better median replacement rates than universal- transfer systems (gap < -10pp against forced-saving), OR (b) forced- saving systems do not show materially lower sovereign pension liability projections (gap < 15pp of GDP against universal-transfer), OR (c) universal-transfer systems do not show lower elderly poverty (gap > +3pp against universal-transfer). Support requires ALL three outcomes to fall in the predicted direction, consistent with the hypothesis that the architectures differ along these dimensions rather than being equivalent.

Panel FE on the three outcomes with architecture category as a set of dummy variables (forced_saving, universal_transfer; mixed is reference). Controls for per-capita income, dependency ratio, female LFP. Primary specification. Secondary: between-country cross-sectional regression of outcomes on architecture category using country-mean values, to capture the level differences that within-country FE absorb. Both specifications reported.

- Claim: Forced-saving welfare architectures (Singapore CPF since 1955, Chile AFP since 1981, Australia Superannuation Guarantee since 1992) and universal-transfer architectures (Nordic model, UK NHS) produce different profiles on two dimensions: (a) retirement-income adequacy for the median retiree, and (b) long-run fiscal sustainability as measured by projected net liabilities of the pension / welfare state over 30+ year horizons. The hypothesis is that forced-saving systems deliver comparable or better adequacy for the median saver with materially lower sovereign fiscal liability, while universal-transfer systems deliver higher redistributive effect (lower elderly poverty rates) at the cost of larger sovereign liability exposure. Both architectures face political-economy pressure to under-save or over- promise; the empirical test compares realised outcomes rather than ideal types.
- Falsification rule: Not supported if on pooled data (a) forced-saving systems do not show comparable-or-better median replacement rates than universal- transfer systems (gap < -10pp against forced-saving), OR (b) forced- saving systems do not show materially lower sovereign pension liability projections (gap < 15pp of GDP against universal-transfer), OR (c) universal-transfer systems do not show lower elderly poverty (gap > +3pp against universal-transfer). Support requires ALL three outcomes to fall in the predicted direction, consistent with the hypothesis that the architectures differ along these dimensions rather than being equivalent.

Estimate
- Error: treatment 'welfare_architecture_category' has no within-country variation under country fixed effects

Strongest opposing argument
Every hypothesis ships with its charitable opposing argument. The framework earns credibility by handling objections at their strongest, not weakest.
Notes
Data-gated. Primary publishers: oecd, world_bank_wdi, imf. Secondary (forced-saving country-specific): singapore_cpf (pending), chile_ spensiones (pending), apra (pending). Until those land, forced-saving measures rely on OECD Pensions at a Glance harmonised tabulations. The hypothesis is pre-registered now to lock the comparison logic; first-run execution waits on publisher readiness.
