Students taking the Land Economics class at Lawrence Technological University in Southfield, Mich., can expect to be simultaneously entertained and schooled in retail economics via shopping center owner Alfred Taubman, who is giving several lectures this term. His first class was replete with retailing history, insights and such quips as why his retail centers are designed for easy exits. "Getting out is just as important as getting in. That man drives his woman there for shopping on Saturday and he has trouble getting out so he can't see a football game? He'll say, 'Don't you ever bring me back here again!'" Taubman told students.
