A RESOURCE FOR THE ECONOMICS FACULTY.

There might be some readers still active in the classroom.  My advice to the teachers of the introductory course is to keep it simple.  "The life of an economics student is easier if he keeps in mind such things as substitution, arbitrage, opportunity cost, and indifference at the margin." There might be reason for a second course to tackle the subtleties, preferably in such a way as to retain one's basic reliance on incentives and decision making at the margin.

A resource called Economic Forces in the Classroom on the Price Theory substack includes elaborations on a variety of topics, classified by subject area and relevance to the first or second course, might be useful,dear colleagues.
