I've posted the slides.
Sorry about the slight mix-up I made today. I have changed the MPL and MPK on the slides so that they are correct — I had missed a coefficient of 1/2 on both of these. However, this change does not affect our calculation of the MRTS.
As mentioned in class, Wednesday's quiz will be almost entirely about the pure exchange (a.k.a. Edgeworth box) economy — graphing, calculating equilibrium and the efficiency concepts.
