I don't get the equations 35-36 on change in terms of trade due to change in endowments. Can anyone explain?</p>

you'll probably get more responses if you point to a link that contains a free version of the paper, assuming there is one ?  Sometimes, if there isn't one,  I email the author directly and ask for a free version if he can spare one. I'm zero for one when emailing the author of that paper.

Vu Tuan: For me to have any hope of following that ( Lucas is one of the clearer writers in macro ), I'd have to start from the beginning and I don't have time right now. Hopefully someone with the time or previous background ( so they can jump right into the pages you mentioned ), can help you.
