Mathematics for Economists:  a review

Department of Applied Economics & Management

Summer 2000

Instructor:                  Paul J.  Ferraro

                                    157 Warren Hall

                                    255-2085 (office)

                                    pjf8@cornell.edu

Classes:                      8:30 am - 12:00 pm

                                    145 Warren Hall

Office Hours:              12:45 - 2:30 pm

                                    145 Warren Hall

Texts:                         Students may use one of two textbooks for this course.  The first,

¡°Introductory Concepts of Mathematical Economics¡± (ICME), is provided to all registrants of the math review course.  An alternative text is Mathematics for Economists by Simon and Blume (SB).  This book was used in Economics 617 in the past.  It may not be used this year, but one can order it through the Campus Store.  In the Course Outline below, reading assignments are given for both texts, but it is generally sufficient to read the references from one text or the other.  A limited number of copies of Simon and Blume are available to be signed out in Warren 145 after class or during office hours.  Please return these copies at the beginning of the next class, and please share them if possible.  Chiang, Searle and Sundaram are on 2-hour reserve at Mann Library Circulation desk under ARME 600.
