The optimal monetary policy in the Barro and Gordon model (pdf, 50 Kb) (Updated April 12 as it is a maximization problem, not a minimization problem we have!

This year we only do a three-hour exam, and the exam set will be correspondingly reduced. Also note, that Walsh's book is this year is based on a new version, so there are some slight variations. I noted that the 2003 exam is a weird version of the set. So here it is (pdf, 70 Kb)
