There is a significant variation in the managerial economics course in terms of the prerequisites, contents and delivery in the MBA programs of AACSB [Association to Advance Collegiate Schools of Business] institutions. In order to get detailed information on these aspects, we conducted a survey of 275 AACSB institutions and reported the results. Briefly, the survey indicates that majority of the programs require principles of economics and business statistics as prerequisites among other things. Based on the survey results, the paper strongly recommends a two course sequence in economics, an introduction to economics as a prerequisite and a managerial economics course in the core of the MBA program.
