I am trying to self-study macroeconomics. I just read parts of "Advanced Macroeconomics" by Romer, and found it a good, intuitive introduction to more advanced models (I have also read a more basic book on ISLM/Solow models and such).
Now I am being told the next step is Recursive Macroeconomic Theory. What are the contents of this book, i.e. what useful topics and methods does one learn that are not present in the Romer book?
Also, I am considering reading either RMT, or maybe something on Business cycles and the short run, which I haven't really read much of, the focus so far in the books has mainly been long-run economic growth... What is recommended to read first?
