Everything you need to know about the economy and what it means for you. This podcast will cut through the jargon to bring you clarity and ensure you finally understand all those complicated terms and phrases you hear on the news. Inflation, GDP, Interest rates, and bonds, Tim Harford and friends explain them all. We’ll ensure you understand what’s going on today, why your shopping is getting more expensive or why your pay doesn’t cover your bills. We’ll also bring you surprising histories, from the war hungry Kings who have shaped how things are counted today to the greedy merchants flooding Spain with Silver coins. So if your eyes usually glaze over when someone says ‘cutting taxes stimulates growth’, fear no more, we’ve got you covered.
