Yes.
Contraband includes products that simply skirt export/import controls.
One of two things may happen:
-
As demand for smuggled products increase, price goes up because demand outpaces supply.
-
Smuggling becomes popular and the market gets flooded with contraband. It causes prices to go down.
#1 is probably more likely unless enforcement isn't prioritized.
#2's likelihood increases when the import controllers are corrupt and susceptible to bribes, because they can look the other way as large quantities of goods are smuggled across a border.
These are not the only possibilities, but their examples of things that have happened at certain times in history.
