Welcome to the web page of the course "Monetary Economics: Macro Aspects," offered at the Masters Programme at Institute of Economics, University of Copenhagen.

On this page you will find a host of relevant information about the course, and the page will be regularly updated. You should therefore visit this page at least twice a week to stay up to date (so, bookmark it right away). For now, you can go to the following places:

Brief Course Description

The aim of this course is to provide an understanding of how and why monetary policy conduct affects important aggregates in the economy, e.g., consumption, inflation and unemployment. Moreover, we will focus on the characteristics of "good" monetary policymaking in the sense of assessing the macroeconomic advantages and disadvantages of various monetary policy strategies. While the curriculum will be mainly theoretical, empirical relevance of the material will not be downplayed.

Particular subjects to be covered include: monetary policy transmission mechanisms; credibility problems in monetary policy; rules versus discretion; the importance of institutional frameworks for monetary policy; goals of monetary policy (which variables to target?); transparency of monetary policy conduct; international monetary policy coordination.

The curriculum will consist of a large part of Carl. E. Walsh (1998): "Monetary Theory and Policy" (The MIT Press), and a number of articles.

Recommended qualifications: As some of the material requires a good understanding of macroeconomic general equilibrium models, it is a prerequisite to have taken third-year Macroeconomics, i.e., to master economic theory at a level corresponding to David Romer (2002): "Advanced Macroeconomics." It is also recommended to be familiar with basic intertemporal optimization, and analyses of dynamic systems (difference and differential equations).

Assessment: Written 4-hour exam; closed book.

The teaching language was in English.

Important note: This course is offered for the first time, and according to plans, another monetary economics course (tentatively named "Monetary Economics: The Economics of Banking"), will be offered in the fall. These two courses can be taken independently, but of importance is that the previously offered course "Monetary Economics" (in Danish: "Kreditvęsen") will not be offered again. The two new courses should be seen as substitutes for that course, and given overlap in course material, one cannot take the present course if one has already taken the old "Monetary Economics" (whether the same rule will apply as regards to the Fall course is undecided for the moment). In short, "Monetary Economics" ("Kreditvęsen"), has been replaced by two brand new courses! (Your are, of course, welcome to show up, but you can't take the exam if you already have passed the old course.)

Revisions of slides, March 21

Note revisions in two sets of slides (both "only" of a technical nature relating to the elimination of the partial derivatives of value functions when doing dynamic programming).

Recap Information

Here, I will post notes where the key concepts covered in recent lectures are listed. These notes will, along with lecture slides, hopefully provide valuable information about what is essential in the curriculum, and what is less essential. Also, in various circumstances, some discussion about what is relevant for the exam (in terms of exemplifying a potential exam question) will be provided.

Recap Information 1: Stylized facts, empirical problems and issues (pdf file, 50 Kb). This note contains general information on how exam questions will be designed, with emphasis on the degree of importance of math (this information will not be repeated in the subsequent Recaps). An example of an exam question is also included.

Recap Information 2: The Tobin effect and micro-founded, flexible-price models with money in the utility function (pdf file, 75 Kb). An example of a technical exam question is included. Note that in the sample question there is a stupid typo in the definition of the functional form of the utility function. There should, of course, be a plus sign in front of the term involving labor supply! See typos for an further explanation. 1000*sorry!

Recap Information 3: Shopping-time models and Cash-in-Advance models (pdf file, 26 Kb).

Recap Information 4: Inflation as a tax (pdf file, 40 Kb).

Recap Information 5: Money's role with incomplete nominal adjustment (pdf file, 39 Kb).

Recap Information 6: Rules versus discretion: Credibility problems (I) (pdf file, 64 Kb). An example of an exam question is included.

Recap Information 7: Operating procedures, interest rates and monetary policy (pdf file, 42 Kb).

Recap Information 8: Monetary policy conduct in "New Keynesian" settings: Credibility problems (II) (pdf file, 41 Kb).

Recap Information 9: Open-economy aspects and monetary policy coordination (pdf file, 50 Kb).

Recap Information 10: Inflation targeting (pdf file, 42 Kb).

Recap Information 11: Transparency of monetary policymaking (pdf file, 67 Kb). An example of a sample exam question is included. This is a question that is slightly "outside" the curriculum, but with your skills, together with what you have learned during the course, it should not be too difficult for you to answer.

F.A.Q. Section

In this section, I will post questions and answers that arise during the course. A fruitful way of communication if you have problems with some of the curriculum, is to e-mail me the problem/question. First, one often solves the issue by oneself by formulating it in writing. Secondly, by writing me an e-mail question, I can provide a much clearer answer than is usually the case in verbal exchange. Finally, when everything is written down, one can make the issue available to all students. This is valuable, as it is quite likely that fellow students have had similar problems with the issue. Therefore, feel free to e-mail questions. I will then make the question and answer publicly available here for everyone's benefit. Of course, your name will not be mentioned (unless you demand so); hence, there is nothing to lose by posing a "silly question" (and by the way: there is no such thing as a "silly question").
