The shadow economy, and the slow work of shrinking it

Ukraine has carried a large informal economy for its entire independent history. The estimates vary by method and none of them are small.

Read it as a calculation, not a character flaw

A small trader stays informal because registering means tax, inspections, accounting costs, and exposure to officials with discretionary power. Staying informal means no legal recourse, no bank credit, no ability to sell to a large customer who needs an invoice, and no pension record.

People weigh those two lists. When the first list is heavy and the second is light, the informal economy grows. That is all it is.

What actually moved the balance

Not enforcement campaigns. Those produce a temporary dip and a permanent resentment.

What moved it was making the formal side cheaper and more useful. A simplified tax regime with a flat payment and minimal accounting, which brought very large numbers of small businesses into the system voluntarily. Electronic filing that removed the visit to an office and therefore the opportunity for a demand. Cashless payment growth, which is the single most effective anti-informality measure ever deployed anywhere, because a card transaction is a record that nobody has to create on purpose.

And the pension link: as it became clearer that declared income produces a real entitlement later, the calculation changed for people in their forties.

What remains hard

Envelope wages in otherwise legal firms — a company registered and paying tax, declaring a minimum salary and paying the rest in cash. That practice responds to payroll tax levels and to whether employees believe the pension system will honour their record. Both are slow variables.

The conclusion I would draw

Formalisation is a service problem before it is a policing problem. Every state that reduced its informal sector substantially did it by making the formal sector worth joining.

Reading the informal economy as a price list rather than a moral failing matches exactly what I see on the ground: people do not choose to stay outside, they calculate the cost of being inside. As the cost of operating formally falls, the informal economy shrinks by itself. More enforcement does not speed that up; it only raises the price.
