Colin Grabow is Associate Director at the Cato Institute’s Herbert A. Stiefel Center for Trade Policy Studies where his research focuses on domestic forms of trade protectionism such as the Jones Act and the U.S. sugar program. Colin is one of the nation's (and therefore world's) leading expert on the Jones Act, a law that's been incredibly harmful to the nation and yet still finds support among those who naively think it somehow benefits an American shipbuilding industry that basically doesn't exist and clearly wasn't spurred to exist by the presence of this harmful protectionist law. President Trump has now repeatedly issued waivers of the Jones Act to try to help minimize the cost of fuel in Hawaii, Puerto Rico, and much of the coastal US. If that's what waiving the act does, why not just repeal it?
