Luxembourg’s productivity debate is no longer about how much the country produces. It is about whether it is becoming more efficient. In its latest annual report, the National Productivity Board put renewed emphasis on “total factor productivity” — a measure of whether the economy is improving the way it produces, not simply expanding.

That distinction matters. An economy can grow by hiring more workers or attracting more capital. “Total factor productivity” is meant to capture something different: better organisation, smarter processes, and stronger use of technology. On that measure, the board said progress had been subdued for more than a decade.

The latest fully harmonised European comparison, for 2023, showed that each hour worked in Luxembourg generated purchasing power equivalent to about €85 in EU-average terms. Across the EU-27, the figure was about €49. Luxembourg remained far ahead on headline output per hour.

Levels versus momentum

The board’s point was that levels and growth are not the same thing. High output per hour does not guarantee sustained efficiency gains. The question is whether firms are continuously improving performance across the economy.

On that broader measure, the board’s diagnosis was cautious. Productivity growth has remained weak, particularly in services. The issue was not sudden deterioration but prolonged stagnation — a slower burn that is harder to reverse.

Finance explains part of the picture. Financial services generate very high productivity levels, yet the board said growth in the sector had been modest for years. Given its weight in the economy, finance shapes the aggregate trend.

But if the weakness were confined to finance, the diagnosis would be straightforward. The more telling test lies elsewhere.

Commerce as a stress test

Commerce provides that test. In 2024, wholesale and retail trade generated €81 per hour worked in Luxembourg. Belgium stood at €71, Germany at €55 and France at €41.

Luxembourg led its neighbours, but the margin was measured in tens of euros, not multiples. In a sector exposed to cross-border shopping, thin margins and digital competition, such gaps offer limited protection.

Commerce is not a specialised niche. It is a broad, everyday part of the economy, deeply integrated into regional markets. If productivity gains remained modest here as well, the explanation could not rest solely on financial dominance.

Scale and constraint

The board distinguished between growth driven by expansion and growth driven by efficiency. Expansion raises output by adding inputs. Efficiency raises output from the same inputs. Over time, living standards depend on the latter.

Luxembourg’s model has long relied on scale through openness — attracting labour, capital and activity into a small domestic base. That approach supports high productivity levels. It does not automatically generate continuous efficiency gains.

If both finance and commerce struggled to accelerate productivity growth, the constraint may reflect structural limits of size in highly integrated markets. In that reading, the challenge is not simply regulatory or fiscal. It is geometric.

No single lever

The board called for stronger innovation, faster diffusion of technology and deeper investment in intangible assets. It also noted that no single lever could reverse the slowdown.

Luxembourg remained one of Europe’s most productive economies in level terms. The debate now concerns trajectory. If the economy is approaching limits imposed by its scale and structure, expectations about future productivity growth may need to adjust.

For a country built on outperforming its size, that would mark a quiet but significant shift.
