Corrections in Hwk 7-(1-v)

In the social planner's problem,
z_1^1,z_1^2,z_2^1,z_2^2 in the
objective function must be
x_1^1,x_1^2,x_2^1,x_2^2.
Also, please assume that Pareto weights satisfy \lamba_i>0 for both i.
Lastly, please ignore "From Claim 1."

I apologize if I confused you and thank Kubota-san for letting me know.

P.S. Other minor typos are:
1) problem after (2-iii) must be (2-iv)
2) Pareto otimal, locally nonsatiated. (comma is needed in-between .)
