Recursive Macroeconomic Theory

“It is the book over which generations of PhD students in macroeconomics have sweated blood. And any good book for PhD students in macroeconomics should be stained with sweat and blood, because it needs to be highly technical. This book is. It’s really difficult from a mathematical point of view. Doing the problem sets are like writing papers. Going through each chapter and then the problem set of the chapter is really challenging and it takes a long time. To cut a long story short, it’s probably the most technical and difficult book you can think of if you want to study macroeconomics.” Read more...

The Best Macroeconomics Textbooks

Raffaele Rossi, Economist

“This is the textbook I use in my PhD macro courses. In fact, it’s used in almost all of the major PhD programmes in the US right now – any respectable programme most likely uses this book. It’s a book of tools and techniques to solve what are called recursive macroeconomic models. Modern macroeconomics uses DSGE models – dynamic stochastic general equilibrium models. That’s a bit of a mouthful, but all dynamic means is that it’s a model which explains how things move through time. So it explains what GDP will be today, tomorrow, the next day and the day after that, and how it might change if the government does different things or if certain things happen in the economy. It’s really a model of how the economy transitions from one point to the next – how it goes into recessions et cetera. Those models are extraordinarily difficult to solve. What this book shows us – and this is the recursive part in the title – is a way of breaking down this really hard problem into little tiny pieces. You can actually solve a much simpler problem when you only have to look at how the economy moves from today to tomorrow. I don’t have to look at how it moves from tomorrow to the next day and all the way out as far as I can see. We can break down these really hard problems into a recursion between today and tomorrow.” Read more...
