Does anybody know of any specific policy initiatives that a country has adopted that has been successful in moving work in the informal economy into the formal economy?
I am looking for 'good practice' policy initiatives that might be transferable from one country and could be implemented more broadly. These might be deterrence initiatives that increase the penalties or improve the risks of detection (e.g., initiatives to improve workplace inspections, improve data mining to identify the informal economy).
They might also be incentive measures that encourage the shift from the informal to the formal economy. These might be supply-side initiatives that make it beneficial and easier to operate in the formal economy (e.g., simpler registration, tax incentives). They might also be demand-side initiatives that encourage consumers/purchasers to buy from the formal economy (e.g., service vouchers, tax incentives).
Finally, they might involve awareness raising and education campaigns to persuade people of the benefits or working in the formal economy or costs of working in the informal economy. Or they might be initiatives that seek to improve the structural systemic drivers that lead to the prevalence of the informal economy (e.g., reducing corruption, modernizing governance).
Ideally, I am looking for specific concrete policy initiatives that have been evaluated to assess their impact.
