I learned a lot from those guys materials:
Lawrence J. Christiano lecture notes
Jezus Fernandez Villaverde teaching materials
Wouter J. Den Haan teaching notes
Karel Mertens courses
Johannnes Pfeifer's codes
I enjoyed reading:
1) On the differences in utility functions for the asset pricing
2) Political risk and macropru
3) How money are created
4) some stuff on term premium, here and here
5) decoupling between short and long rates
