President Trump's team seek to renegotiate parts of NAFTA to encourage the revitalization of U.S manufacturing. How is consumer welfare affected if there is some domestic protectionism to keep foreign imports out? In our 2015 paper, we explore this theme in the case of public transit buses. We argue that the "Buy America Act" encourages urban transit agencies to purchase U.S produced buses. This shield stops cities such as Santa Monica from buying cheaper, more energy efficient buses from Japan and South Korea. This protectionism gives some monopoly power to small inefficient U.S producers. The net effect is a more expensive fleet that is less fuel efficient than the rest of the world's. Is our sector case study a preview of our medium term future?
