Books

There is not a prescribed text for the course.

The most complete book on monetary economics presently published is Walsh, Carl. (2003) Monetary Theory and Policy. MIT Press. but the following are also highly recommended books:

Gali Jordi (2008) Monetary Policy, Inflation, and the Business Cycle Princeton University Press -- the best introduction to New Keynesian models � we will follow this book quite closely, especially chapters 2 to 5 � check material on Gali�s website

Woodford, Michael, 2003, Interest and Prices. Princeton University Press -- difficult read, very analytical � 1st chapter is required reading � again, have a look at Woodford�s website

Obstfeld, Maurice, Kenneth Rogoff, 1996, Foundations of International Macroeconomics, MIT Press -- an open economy focused presentation but probably the best macroeconomics book available at the moment. Some open economy issues will be analyzed following their presentation

Professor Harald Uhlig provides an implementation of the Smets and Wouters model which makes easy experimenting with the calibration of the model Download here. This exe-file, once executed, will install a program on your computer which allows you to get impulse responses to various shocks in the Smets and Wouters (JEEA, 2003) model.

A Methodological Discussion: Now that you have some idea of the working of this class of models frequently used in policy analysis, it is worth thinking a bit methodologically. Here are 4 contributions to start with.
