In spring 2019 I’m teaching the macro principles class for the first time in a few years — and I’m looking forward to it. I’m a regular participant in our department’s weekly macro seminar and I have some new material and in-class tricks to try out. One important note at the start: Macroeconomics is harder than you’d think if you spend much time on social media. There, people get lots of agreement when they say the case is “overwhelming” for one macro policy and there’s “no evidence” for another. Trust me, on all of the major controversies, from the minimum wage to monetary policy, there are no overwhelming cases or totally unsupported positions. With the framework of introductory macroeconomics, though, you can make sense of the competing arguments and come to a reasoned judgment. Here we go!
