Policymakers in most OECD countries face the challenge that they must ﬁght people smuggling while retaining control of migration ﬂows. Policies designed to increase border controls are not suﬃcient on their own; the level of enforcement that would eliminate people smuggling entirely would be extremely costly. Further, these policies have unintended consequences in the people smuggling market; they increase the fees charged by smugglers, increase reliance on their services, and increase their cartellization. By contrast, a visa-selling policy can weaken smugglers by decreasing their prices and squeezing their proﬁts. However, eliminating people smuggling only in this way requires cheap visas and necessarily leads to a rise in the numbers of people migrating. An innovative policy of selling visas combined with enforced sanctions on employers and employees for illegal working can control migration ﬂows and put smugglers out of business. Using the revenue generated to ﬁnance enforcement allows visa prices to be set at a high level that controls migration ﬂows.
