Belgium public-debt trajectory 1979-1992 (69% → 135% GDP)

BEL·1979 – 1992·Martens coalitions (variable)candidate

What the policy did

Stylised-fact entry capturing debt accumulation across the Martens era. Debt/GDP rose from 69% (1978) to 135% (1993) — one of highest in OECD by late 1980s. Despite devaluation and special-powers consolidation, high real interest rates and pension/health expansion kept primary balance insufficient. Debt reduction required sustained primary surpluses from the 1990s under Dehaene and Maastricht discipline.

Policy-content fingerprint — what this policy moved, on which axes

Large welfare states sustain long-run real GDP per capita growth when paired with market flexibility (low product- and labour-market barriers), trade openness, and fiscal discipline (debt-to-GDP below 90%), but not when paired with rigid product and labour markets, in an OECD and rich- country panel 1980-2020.

The Soviet central-planning system, having already exhibited TFP stagnation 1970-1989, underwent a canonical institutional and economic collapse 1989-1998 as plan-enforcement was withdrawn without functioning market institutions in place.

Across the OECD 38, over 2000-latest, larger general government final consumption as a share of GDP is associated with slower growth in real household disposable income per capita, controlling for demographics, initial-income level, energy-price exposure, and trade openness.

Credible fiscal consolidation episodes — defined as sustained primary balance improvement of at least 2% of GDP over 3 years, not reversed within 5 years, and accompanied by declining debt-to-GDP trajectories — predict stronger subsequent 10-year real GDP per capita growth and private investment than repeated discretionary fiscal stimulus in mature economies, in an OECD panel 1980-2020.
