PIIE Senior Fellow Chad P. Bown and Soumaya Keynes of The Economist examine what a no-deal Brexit would look like, or the economic implications if Britain were to split from the European Union without a new trade deal. They talk with Professor Swati Dhingra of the London School of Economics about her research on what reverting to World Trade Organization (WTO) tariffs would mean for the United Kingdom. They also discuss looming nontariff barriers to trade in sectors like pharmaceuticals, aviation, and financial services.
