HW 9 & 10 Graded

Finished grading HW 9 &10. I will bring them to the class in June 30. If you want them before the class, please come to my office to pick them up. I put them in the mail box in front of room 426 by the class, and after the class.

This time, I gave A for 12 students, B for 7 students, and C for 1 students. Kubota, Ino, and Tsukahara received A+ for their excellent performance.

I feel you all have done fairly well. Few students made major mistakes. The difference between grade A and B is just whether you can make a clear and convincing argument. Some students only put the answer, and did not exposit the logic to reach it. We less evaluate such a paper.

If you had any question, feel free to ask me.

Kohei

Additional assumption for hwk 8- (3-3)

Please note that in (3-3), x_h^i denote the demand of good h for consumer i.
There may be several ways to solve this problem.
If you need to assume u_{12}^2, u_{21}^2>0, please do so.
(where u_{12}^2 =\frac{\partial^2 u^2 (x_1^2,x_2^2;a)}{\partial x_1^2 \partial x_2^2}.)
