Trade has come up in all of the episodes of Summer School so far. An early use of money was to make trade easier. Trade was responsible for the birth of companies and the stock market. And trade was the lifeblood of the early United States. Today's episode covers 250 years of trade history in three chapters. We start with one of the founding texts of economics, Wealth of Nations, in which Adam Smith argues a country's true value is not measured in gold and silver, but by its people's ability to buy things that enhance their standard of living. Then we'll watch American politicians completely ignore that argument in favor of protecting domestic industries – until one congressman makes a passionate case for free trade as the means to world peace. And finally we'll follow the trade debate up to the modern day, where the tides of American politics have turned toward regulation. This series is hosted by Robert Smith and produced by Audrey Dilling. Our project manager is Devin Mellor.

Episodes each Wednesday through labor day. Find all the episodes from this season here. And past seasons here. And follow along on TikTok here for video Summer School. Planet Money Summer School has arrived at the birth of the United States and the chance to set up a whole new economy from scratch. Should there be a centralized bank? Should there be a single currency? We'll travel to two moments in the country's early history when the founders said "nope" to these questions and see what happened. First we'll witness one of the great economic battles in U.S. history – the president of the United States versus the president of the Bank of the United States – and see how the outcome ushered in an age of financial panics. Then we'll drop in on a time before the U.S. dollar existed as we know it, when you could buy things using one of about 8,000 forms of money circulating in the country. We watch as the Civil War leads to the first standard currency. Along the way, we'll learn why the cycle of economic booms and busts persists to today despite efforts to centralize America's economy throughout history.
