How does stricter border surveillance typically affect formal cross-border trade and migration?

• A. Increases formal trade and reduces smuggling
• B. Reduces formal trade and potentially increases smuggling and illegal migration
• C. Has no effect on trade or migration
• D. Eliminates migration entirely

Answer: (B)

Stricter border surveillance raises the costs and risks of crossing and moving goods, which tends to push activity away from formal, documented channels. For cross-border trade, firms face longer clearance times, higher compliance costs, and a greater chance of penalties or disruptions at checkpoints. These frictions make formal trade less attractive, so volume can fall as traders seek cheaper or quicker alternatives, adjust shipment sizes, or reroute through less regulated paths. At the same time, the higher risk and cost of enforcement can push people and goods toward illicit routes, increasing smuggling and irregular migration as windows to move across borders become more constrained or expensive through official channels. So, the typical outcome is a decline in formal trade and a potential rise in smuggling and illegal migration, rather than the opposite or an outright elimination of movement.
