Homework Problems: Please type all assignments, if possible.  Write in equations by hand, or

paste them in from the lecture notes. Word has an equation editor, or you can use mathtype

(a trial version will get you a long way). All homework assignments are due one week from the day

of the class they are assigned, however, you may turn in HWs by 2pm Friday the week they are due

by putting them in the blue envelope on my door.  Late HWs will be marked down as we often

discuss answers in class the week after they are due. 

 

Problem Set #1: Due 09/16: Romer Page 91-92 Problems 2.1a ; 2.2 ; for #2.5 set up the

Lagrangian and first order condition; Do #2.6 a-c for a productivity speed up (not a slowdown),

using the answer to 2.6d given in the class calendar announcements, but you should do 2.6e. 

 

Course Description:  This course reviews several topics in advanced macroeconomics,

assuming at least one previous graduate course in Macroeconomic theory. As it is a somewhat

technical course, reading several authors’ explanation of the same problem often proves helpful. 

This explains the number of recommended texts included below, most of which are on reserve in

Walsh. Our main text is the aptly named Advanced Macroeconomics 2nd ed by David Romer.

We begin where the Solow model leaves off, with some theories of optimal saving.  This is high

theory but not purely academic as some people (countries) do save, even as Americans save less

these days. That Americans save so little, public or private, brings about the first of several

 conundrums addressed during out otherwise theoretical tour of macroeconomics: why is the

current U.S. current account deficit so large and will it shrink gradually or implode? This is

perhaps the macroeconomic question of the day.  Social security reform is another topic optimal

savings models should be able to address, albeit not politically. Another macroeconomic puzzle

 is high unemployment in France and Germany’s compared to the US and UK. One last mystery

is a modern macroeconomic policy success: what explains the world-wide disinflation of the

1990s? Perhaps this victory explains why monetary economics has become its own branch of

macroeconomics. We discuss the broad outlines of how this happened and the extent which the

greatly reduced cyclical volatility of the past 20 years is due to good monetary policy or good

 luck (or perhaps to retiring Alan Greenspan). Another 20 years like this and the study of business

cycles will be an Economic history course. Finally, we turn to the reality of an uncertain, stochastic

world. Here we sample modern time series econometrics and a small dose of stochastic calculus,

 just enough to make use appreciate why finance and economics has proved such a successful

field of economics

 

Course Requirements: There will be several problem sets in preparation for a midterm in

preparation for a final exam (in preparation for the comprehensive exam in macroeconomics

 next spring).
