Some Solutions (updated)

Here are some more samples questions and solutions. These are from previous years, so not all of the material is relevant (figuring out what is relevant is a good test!);

• Growth
• One Period Model
• Two Period Models

I also have an accumulation of past final exams with some comments about the solutions. The comments refer to other solutions that may or may not agree with the above solutions. Again, not all of the material is relevant.

• Previous Final Exams

The solutions to the review questions previously posted are somewhere within the material here, with the exception of Keynes. I thought I had some Keynes solutions from last Fall. I'm still looking. If I don't find them and I get some time I will try to post this afternoon.

update: The Keynes Notes have been updated to include the solution to the sample question.

Review Questions for the Final

I have posted some review questions for the final here. Remember that the final is cumulative, including the material covered by Professor Huynh. The review session will be on Tuesday evening at 8pm. I will post the room location sometime later. Study well.

Homework #2

Here is the second homework, due at the start of class on Thursday. It uses the Keynes assumptions from the previous post.

Simple Keynes Model Assumptions

Here are some notes for a simple model of Keynes. Note that is NOT the standard Keynesian model that is in all the textbooks (chapter 12 in Williamson's Third Edition). This model allows aggregate demand to affect the economy. When aggregate demand affects the economy then financial frictions can have real effects on the economy. This is at the heart of Keynes' Theory in The General Theory, not sticky nominal wages. The sticky nominal wages are just an assumption so that the financial frictions and investor psychology can affect the economy. For this last point see the new and very intersting book by Akerlof and Shiller: Animal Spirits. We will be talking about this in class on Tuesday.

Exam One Solutions

Suggested solutions and a general grading algorithm for exam one can be found here.
