These teacher developed case studies taken from the business world are presented to help secondary students develop an understanding of economics and of the decision-making process. The studies describe real business situations. All historical and current facts are provided for each of the seven case studies. In the first case, students debate whether the lobby for a shoe corporation should be in favor or against shoe import quotas from Taiwan and Korea. In the second group of studies, students acting as Field Supervisors of Collections for the Public Service Company must make some tough decisions on what customers will be shut off. In the third case study, students must decide upon the most profitable layout for a self-service, neighborhood discount department store. Students must decide on a sales program for a company in the data processing industry in the fourth case study. The fifth case study involves students in reading the Sheraton Corporation's case against a current bill on the minimum wage before the House of Representatives. Students acting as members of the House must decide how they would vote. The last two case studies involve students in making decision concerning advertising for the Howard Johnson restaurant chain and implementing new ideas for the Filene retail department store.
