Problem Sets

Problem sets are normally due Thursdays at the start of class.Assignments & due dates are subject to change: Please listen to class announcements and check this page.

Problem Sets are in part from Romer's book (4th or 5th edition), and in part from the Collection of Practice Problems:

(1) Due 10/4. Practice problems 1.1 and 1.3.

(2) Due 10/11. Romer problems 1.3, 1.4, 1.6.

(3) Due 10/18. Practice problems, 2.1-2.4.

(4) Due 11/1. Romer problems 2.1, 2.2, 2.4. Practice problem 3.1.

(5) Due 11/8. Romer problem 2.6. Practice problem 3.2.

(6) Due 11/15. Romer problems 2.9-2.10. Practice problems 3.3-3.4.

(7) Due 11/29. Practice problems 4.1(a,b), 4.2-4.3.

(8) Due 12/06. Romer problem 2.17. Practice problems 4.4-4.7.

Textbooks: There are many good textbooks on Economic Growth, but none is perfectly suitable for this class. I am also reluctant to require a purchase for a 10-week course that covers only selected chapters.

Romer "Advanced Macroeconomics" has the basics: some chapters will be required and I will assign problems from this book. The 4th and 5th editions are so similar that either one is fine.

Barro/Sala-i-Martin "Economic Growth" presents the Solow model and optimal growth in great detail and it has an excellent technical appendix (highly recommended), but it does not cover OG.

Jones and Williamson are undergraduate texts, perhaps useful if you find Romer or Barro/Sala-i-Martin difficult to follow.

Acemoglu "Modern Economic Growth" provides a high-level and quite encyclopedic coverage, perhaps appropriate for independent reading if you find the class too easy.

Course Outline:

Some overheads/lecture notes will be provided later, to be updated.

Required readings are exam-relevant even if not covered in class. The class covers more than the required reading, often extracted from a variety of other sources that are listed as recommended, optional, or for-reference (in order of relevance). Items not required are only tested to the extent they are covered in class.
