Real Business Cycle

Christoph has sent me some lecture notes for the real business cycle model and asked me to put them on our website. The notes also use the Romer textbook as the reference. We've "covered" these topic in one of the problem sets. Hence, maybe they are useful for some of you.

One question could be, how the RBC-model and DSGE model are linked with each other? Or why do we use DSGE models instead of RBC models to explain output fluctuations? What are the strengths and weaknesses of both models?
