The Hidden Geometry of Growth

In January 2026, the OECD published Portugal: Insights on productivity based on microdata, analysing firm-level labour productivity between 2004 and 2022 using MultiProd indicators.
The headline is familiar: productivity remains below the OECD average. Between 2010 and 2022, average annual growth reached approximately 1.3%. Improvements were relatively widespread across firms, including among those at the lower end of the distribution. Yet productivity gaps between the most and least efficient firms remain substantial, and cross-industry reallocation plays a limited role.

What matters here is not the level of productivity; it is the pattern.

When productivity growth is driven primarily by within-industry improvements rather than by the reallocation of resources toward more efficient firms, the system signals incremental adjustment rather than structural transformation.

In high-performing economies, productivity growth typically reflects a combination of technology diffusion, managerial upgrading, mobility of capital and labour toward higher-value activities, and disciplined renewal through restructuring or exit. When one of these transmission channels operates below potential, dispersion persists.

Persistent dispersion is rarely a purely microeconomic issue. It often reflects deeper systemic frictions: regulatory thresholds that inhibit firm scaling, financial constraints that slow capital deepening, labour market rigidities that limit mobility or governance environments that prioritise continuity over renewal.

For boards and public decision-makers, this distinction is crucial. Productivity does not improve simply because firms invest. It improves when systems enable efficient circulation of resources and sustained alignment between incentives, regulation and capability.

Microdata reveals something that aggregate indicators conceal: structural inertia.

When dispersion remains wide and reallocation weak, growth becomes path-dependent. Economies expand, yet their internal configuration changes little. Incremental gains accumulate without fundamentally altering the geometry of performance.

This is where the discussion moves beyond macroeconomic aggregates.

In complex systems, whether national economies, regional health networks or multi-sector institutions, performance depends on how effectively bottlenecks are identified, misalignments corrected and renewal mechanisms embedded into governance structures.
Without these corrective adjustments, underperformance is absorbed rather than resolved.

The OECD analysis therefore exposes more than a productivity gap. It points to the quality of systemic refinement.

Economic expansion does not automatically generate structural improvement.
Systems evolve when internal misalignments are deliberately corrected and coordination mechanisms are strengthened over time.
