The comments made earlier about the importance of seeing how the concepts of the course apply to problem sets are very relevant to Economics.  Also, you should be aware that what's causing a student difficulty may not be Economics but rather Mathematics.  For example, in Econ 111, it is very important to be able to read and interpret graphs.  If you find that a student is having difficulty with the mathematical aspects of the course, you might ask the course instructor if there is any review material in graphs that you could use when tutoring the student.

From Your Professor

The most important thing is for students to do problems with the tutor, so that their mistakes will generate questions. It is vitally important for the tutor to avoid jumping in and solving the problem when the tutee gets stuck.  Instead, getting stuck should be recognized as an opportunity to identify and resolve confusions.
