The 289-Day Experiment

In the AI Story

The experiment emerged from the Institute's methodological commitment to empirical fieldwork rather than theoretical argument. Existing development economics discussed institutional barriers abstractly; the Institute proposed to measure them concretely. Researchers chose a small garment workshop as the test case — an enterprise ordinary enough that thousands of actual entrepreneurs faced identical procedures.

The researchers followed every official requirement precisely. They did not pay bribes, did not pursue shortcuts, did not leverage political connections. The point was to document what the system actually required of a compliant participant of ordinary means. The 289-day figure represented this baseline compliance cost — the minimum institutional friction, not the worst case.

The experiment's findings were devastating for orthodox accounts of why the informal economy persisted. The informal sector was not avoiding formalization out of preference for illegality or ignorance of formal benefits. It was being excluded by a registration process whose cost exceeded what an ordinary person could bear. The formal system was functioning as designed — designed for formal participants, with no consideration for the people standing outside its walls.

The experiment has been replicated in multiple countries with similar findings. Egypt, Haiti, the Philippines, and other nations showed registration processes of comparable or greater friction. The pattern established a structural diagnosis: institutional exclusion was not a Peruvian anomaly but a global phenomenon with specific, measurable mechanisms.

The experiment's influence extended into reform design. The finding that institutional friction was measurable implied that it was reducible. Subsequent reforms in Peru and elsewhere specifically targeted registration time and cost as variables to be optimized, with significant results. The World Bank's Doing Business reports institutionalized this measurement approach globally, tracking registration costs across economies as a development indicator.

Origin

The experiment's conception reflected de Soto's training in practical institutional analysis rather than academic economics. His background in Swiss international finance had given him direct experience with how formal institutional systems actually operate — and what distinguished those that function smoothly from those that impose excessive friction. The Institute's 289-day finding quantified this friction for Lima.

The choice to count days, trips, and fees rather than to theorize about institutional barriers reflected a methodological commitment that became the Institute's signature. The empirical specificity made the finding difficult to dispute and impossible to ignore.

Key Ideas

Institutional friction is measurable. The experiment transformed an abstract concept into a specific empirical finding with policy implications.

The friction is the exclusion. 289 days and thirty-one months of minimum wage are not barriers to formalization — they are the formal system functioning as a filter.

The pattern is global. Subsequent replications in other countries confirmed that excessive registration friction is a structural feature of formal systems designed without the informal sector in mind.

Measurement enables reform. Specific friction points can be specifically reformed — a diagnosis that opened pathways to institutional change that abstract analysis had not.

The AI parallel. The registration barriers for extralegal AI builders — Stripe compliance, cloud deployment costs, IP enforcement — are the 289-day experiment's structural analog.

Debates & Critiques

Whether registration friction is the primary barrier to informal-sector inclusion or merely one among several has been contested. Critics argue that even with simplified registration, the informal sector would continue to face barriers in credit access, market participation, and labor regulation. De Soto's defenders note that the 289-day finding did not claim registration was the sole barrier — only that it was measurable and specifically reformable, and that reducing it would not exhaust the institutional reform agenda.
