Economics Struggles to Cope With Reality

There are basically four different activities that all go by the name of macroeconomics. But they actually have relatively little to do with each other. Understanding the differences between them is helpful for understanding why debates about the business cycle tend to be so confused.

The first is what I call “coffee-house macro,” and it’s what you hear in a lot of casual discussions. It often revolves around the ideas of dead sages -- Friedrich Hayek, Hyman Minsky and John Maynard Keynes. It doesn’t involve formal models, but it does usually contain a hefty dose of political ideology.
