The government in Singapore very effectively incentivises cleanliness by littering fines, Corrective Work Orders for repeat offenders (put on orange vest, go pick up trash for a day), and a small army of laborers cleaning up at night.
Birth incentives don't work quite as well, because a $500 voucher doesn't go very far in a country where a public housing flat can sell for $1,000,000 and the schooling system is a pressure cooker mandating extensive paid tuition.
