When we talk about theft in international trade, we usually mean piracy, smuggling, or copyright infringement. Professor Leif Wenar, of King’s College London, thinks that we might be missing the forest for the trees. Illegal transactions across borders are going on every day on an enourmous scale. Consumers cannot help buying stolen goods when they buy gasoline and magazines, clothing and cosmetics, cell phones and laptops, perfume and jewelry. Worse, the money consumers spend at the mall and the filling station ends up in the hands of some of the most brutal rebels and repressive regimes in the world.
