The Weekly Tradecast looks at tariffs with Emily Blanchard, a former Chief Economist at the U.S. State Department. Not long ago, we were deep in a cost-of-living crisis. Inflation has now eased a bit but geopolitics remain tense and the global economy is still struggling to recover. But rather than moving towards more open trade, many countries are becoming more protectionist. Adding to the unease, countries are threatening to slap huge tariffs on major trading partners. In the current climate, there are fears that escalating tariffs could lead to trade wars - a scenario with grim prospects for many developing countries. For more on the ins and outs of tariffs, tune in to Emily Blanchard from the Tuck School of Business at Dartmouth College.
