Textbook
Microeconomics: Theory and Applications, by Edwin Mansfield and Gary Yohe, 11th
edition, W.W. Norton Company
Course Description
This is an intermediate course open to students who have successfully completed an
introductory (Econ 1000) or principles course in microeconomics (Econ 2010) and have
also completed a mathematics course for economists (Econ 1078) or a mathematics
module course (like Econ 1050, 1080, 1100). It is essential that the students have
knowledge of basic calculus. This course discusses economic choice behavior of
consumers, producers, and such other economic agents to understand functions, successes
and failures of markets. The course also analyzes interrelations among different types of
economic agents and markets.

Accommodations for Students with Documented Disability
If you qualify for accommodations because of a disability, please submit to the instructor
a letter from Disability Services in a timely manner so that your needs may be addressed.
Disability Services determines accommodations based on documented disabilities.

Absences due to Religious Observances
Campus policy regarding religious observances requires that faculty make every effort to
reasonably and fairly deal with all students who, because of religious obligations, have
conflicts with scheduled exams, assignments or required attendance. In this class if you
have any such conflict, please inform the instructor at least two weeks in advance to
make a reasonable arrangement or adjustment according to the University policy, which
Classroom Behavior Policy
Students and faculty each have responsibility for maintaining an appropriate learning
environment. Students who fail to adhere to such behavioral standards may be subject to
discipline. Faculty has the professional responsibility to treat all students with
understanding, dignity and respect, to guide classroom discussion and to set reasonable
limits on the manner in which they and their students express opinions. Professional
courtesy and sensitivity are especially important with respect to individuals and topics
dealing with differences of race, culture, religion, politics, sexual orientation, gender
variance, and nationalities. Class rosters are provided to the instructor with the student's
gender pronoun. Please advise me of this preference early in the semester so that I may
make appropriate changes to my records. See polices at
Discrimination and Harassment Policy
The University of Colorado at Boulder policy on Discrimination and Harassment
policy on Sexual Harassment and the University of Colorado policy on Amorous
Relationships applies to all students, staff and faculty. Any student, staff or faculty
member who believes s/he has been the subject of discrimination or harassment based
upon race, color, national origin, sex, age, disability, religion, sexual orientation, or
veteran status should contact the Office of Discrimination and Harassment (ODH) at 303492-2127 or the Office of Judicial Affairs at 303-492-5550. Information about the ODH
and the campus resources available to assist individuals regarding discrimination or
harassment can be obtained at http://www.colorado.edu/odh.
