The Missing Middle or the Hidden Middle?

The Medium-Sized Firm Doesn't Know It Doesn't Exist

This question does not sit comfortably: do medium-sized enterprises actually disappear from Arab economies, or can our statistical data systems simply not detect them? The difference between these two answers is not merely academic; each path leads to an entirely different set of development tools, and a misdiagnosis here costs billions of dollars in misdirected development financing.

The Puzzle of Prevailing Economic Wisdom

The prevailing assumption holds that financing flows either to micro-projects or to large corporations, and that the middle ground between them is a genuine "gap" in the structure of the economy. But what if the diagnosis itself is the problem? That is the core of the puzzle: is the middle genuinely absent, or do our statistical tools simply capture only what floats to the surface?

What Is the "Missing Middle"? (The Classical Theory)

In the classical development literature, the "middle range" — by firm size — is described as a wide gap in an inverted-U distribution: very high density among very small firms, very high density among very large firms, and a noticeable void in between. The conventional conclusion is that this middle is absent because of weak financing, small banks, and a hostile business environment. But that conclusion assumes the void is real — which is precisely what more recent literature has begun to question.

The Analytical Inversion: From "Missing" to "Hidden"

A re-reading of Hsieh & Olken (2014) turns this conventional conclusion on its head: the "cutoff point" at which firms disappear matches strikingly precisely with specific regulatory thresholds (licensing limits, labor inspection triggers, tax registration). The new conclusion: firms do not disappear because they fail to grow — they deliberately choose to stay small. Staying small is not failure here; it is a deliberate survival strategy.

Regulatory Thresholds as Barriers to Emergence

Three regulatory thresholds in particular drive this strategic evasion: licensing requirements (compliance costs that rise with firm size), labor inspection (regulatory standards that kick in at a specific worker count), and tax registration (thresholds that impose harsh financial burdens the moment they are crossed). The result is a clear strategic behavior: growth means regulatory punishment, so the firm chooses to settle just below the threshold rather than cross it.

The Gray Zone: A Boundary on Paper, Not in Reality

The line separating the formal and informal economy is not an actual barrier — it is closer to a line on paper that firms cross daily. The middle range is not absent; it is active and vital within value chains, even as it operates in this gray zone between formal and informal. And this is precisely where the flaw lies: our view assumes solid boundaries where only shifting behavioral ones exist.

The Statistical Reality in Arab Economies

The practical dimension in the Middle East and North Africa region indicates that roughly 20% (a fifth) of the sales and labor of officially registered firms goes unreported in official statistics. The essential point here: we are not talking about random, wholly unregistered entities — we are talking about legally existing entities that hide a large part of their activity from official systems.

The Partial Blindness of Statistical Monitoring

Can our current tools — trade registries, tax data, sectoral surveys — detect firms as they cross into this gray zone? The honest answer is that they suffer from a "partial blindness" that prevents them from detecting firms as they make that crossing, keeping such firms off the radar screen entirely — and therefore beyond the reach of any precisely targeted financing aimed at them.

Why This Distinction Matters: A Diagnostic Matrix

Each diagnostic path leads to an entirely different set of tools. If the middle is genuinely missing (Path A), the goal is to create firms from scratch, and the tools are incubators, seed financing, and programs that convert micro-projects into medium-sized ones. If the middle is hidden (Path B), the goal is to reveal firms that already exist, and the tools are regulatory reform, new statistical instruments, and financing designed for those who do not appear in the records. The two paths do not intersect — and a misdiagnosis here is extremely costly.

A Financing Gap, or a Measurement Failure?

Should we acknowledge that the "missing middle" problem in our region is, at its core, a measurement problem — a failure to capture the true scale of informal projects and activity — before it is a financing problem of scarce resources or weak bank lending? Financing directed at solving a misdiagnosed problem is a genuine developmental waste, however good the intentions behind it.

The Implications for Firm-Support Efforts

Acknowledging that the middle is "hidden" rather than "missing" carries four implications: realistic support design that recognizes the fluid movement of firms between formal and informal status, rather than forcing them into an immediate mold; smarter statistical capture that develops surveys going beyond static registries to detect actual activity in the gray zone; innovative financial targeting that designs financing tools based on value-chain assessment rather than official books alone; and regulatory reform that re-engineers tax and labor thresholds so that growth is no longer punished.

A Strategic Reflection: The Iceberg

Can statistical systems in Arab countries detect firms operating in the gray zone, or do our tools only capture what floats on the surface? The official measurement is the visible tip of the iceberg above the waterline; the hidden middle in the gray zone is the unmeasured mass beneath it — and in most cases, it is far larger than what official statistics ever capture.

Closing Thought

In Arab economies, medium-sized firms exist, but they pay a "growth tax" that pushes them toward the shadows rather than full visibility. Fixing the lens through which we see the economy comes before pumping money into it. So is the middle genuinely absent — or is it our statistics that are missing?
