Hey everyone, I have a problem to compute an equation i just read in an economics paper that was on my reading list. I simply cannot compute it in Maple and I have no further idea how to grasp it. Any suggestions are HIGHLY appreciated ;) http://21coe-glope.com/paper/21COE_WP3.pdf [Broken] The problematic forumla is (3) on page 7. But instead of defining D to be a constant, i want D to be dependent on Y. For simplicity take D==Y.... I now want to solve this for X** as in equation (4). Hope any Maple pro is able to help me. thank you guy in advance!
