Microeconomic principles 2010 introduces you to the "economic way of thinking." The central fact that underlies economics is the fact of "scarcity." By this it is meant that our wants exceed the goods freely available from nature--hence choices must be made among the many things we want. This leads to the fundamental economic questions, narrowly defined, which face all societies: What to produce? How to produce? and For Whom to produce? But economics is really much broader in scope than this; it is really the study of wise decision-making in all areas of life. To draw a biological analogy: The "ecosystem" of microeconomics is competitive equilibrium, with supply and demand determining prices and quantities exchanged in each of a plethora of individual markets (interacting "forests"). The "trees" that make up each forest are the individual economic agents (households and firms, but other collections of people as well) whose "optimizing" behavior we shall study extensively. All sound decisionmaking involves comparison of benefits with costs--when benefits exceed costs for an action the decisionmaker is made better off by taking that action. While this all may seem rather dry and unclear at this time, economics is hardly the "dismal science" it has been tagged as (by T. Carlyle); rather I have high hopes that you will find it live and exciting.

Office: Economics 223 Hours: Tuesday-Thursday 3:30pm-4:30pm (also right
after class and
by appointment at many additional hours, if there are schedule
conflicts)
Phone: (303) 492-7021 (message machine), but the strongly
preferred

NOTE: 1) The final exam date is: December 18th (a
Tuesday) 10:30am-1:00pm. The exams are in our usual
classroom. This information is
repeated at the
end of the syllabus...there are no makeups...do not make plans (airline
tickets, etc.) that involve leaving early. The Economics
Department has recently instituted more stringent grading requirements
that I must follow. The grade of IW has been completely
eliminated, while the grade of IF will only be given in situations in
which a student is unable to complete a course for reasons completely
beyond their control. Such situations must be discussed with me
immediately, or an F will be assigned for the course grade. If
you have three or more finals in one
day, it is the last final that is to be changed according to
University
policy, so there should be no need for make-ups this semester;
2) Students with disabilities
who qualify for academic accommodations must provide a letter from
Disability
Services (DS) and discuss specific needs with me, preferably during the
first two weeks of class. DS determines accommodations based on
documented
disabilities (303-492-8671, Willard 322, www.colorado.edu/sacs/disabilityservices).
Campus policies
(including those involving the new student honor code, plagiarism,
classroom
behavior policies, and the like) can be viewed at:
http://www.colorado.edu/policies/index.html.
Direct any questions you have about these policies to me.
3)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, it is unlikely that this
will be a problem, since I do not take attendance in any event.
Should we be voting for a test date that conflicts with religious
observances, point this out to me and that date will be eliminated from
consideration. See full details at http://www.colorado.edu/policies/fac_relig.html
4)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 have 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 legal name. I will gladly honor your request to address
you by an alternate name or gender pronoun. Please advise me of this
preference early inthe semester so that I may make appropriate changes
to my records. See polices at:
http://www.colorado.edu/policies/classbehavior.html
and at http://www.colorado.edu/studentaffairs/judicialaffairs/code.html#student_code
5)All students of
the University of Colorado at Boulder are responsible for knowing and
adhering to the academic integrity policy of this institution.
Violations of this policy may include: cheating, plagiarism, aid of
academic dishonesty, fabrication, lying, bribery, and threatening
behavior. All incidents of academic misconduct shall be reported
to the Honor Code Council (honor@colorado.edu; 303-725-2273). Students
who are found to be in violation of the academic integrity policy will
be subject to both academic sanctions from the faculty member and
non-academic sanctions (including but not limited to university
probation, suspension, or expulsion). Other information on theHonor
Code can be found at http://www.colorado.edu/policies/honor.html
and at http://www.colorado.edu/academics/honorcode/
Grading:
I have an unusual and complicated (but extremely fair!) grading system.
There will be two midterms and a comprehensive final. On each
multiple-choice
exam enough points are added to everyone's bring the median score up to
75. NOTE: it is points that are added not questions,
where
a question is typically worth 4 points on a midterm of 25
questions.
So, for example, if the median for a particular exam is 68 (the average
person misses 8 four-point questions), 7 points will be added to each
person's
exam (the equivalent of 1.75 questions). Hence, doing well on a
difficult
exam, say getting a 96 (missing one question) when the median was 68
(missing
8 questions) enables you to get over 100 points, in this example
receiving
a 103. Should the median for an exam be above 75, I do
not subtract
(such an outcome indicates either that you are part of an unusually
smart
or studious class or--more likely?--that I made the test too easy,
hence
it is my problem). After these adjustment points are added, I will
calculate
your course test grades as the largest number arising from the
following
alternative calculated scores:
"Score 1": .3(1st Mid Grade) + .3(2nd Mid Grade) + .4(Final Grade)
"Score 2": .4(2nd Mid Grade) + .6(Final Grade)
"Score 3": .4(1st Mid Grade) + .6(Final Grade)
Hence, if you "mess up" (or miss) either of the midterm exams (but not both), that test will automatically be dropped; the comprehensive final is weighted more heavily in this case. There will be no early exams or make-up exams, since they are difficult to make comparable and this system does not penalize you for missing one exam in any event. Should you miss an exam, come to my office and get a copy of it and take it under "test conditions," later comparing your answers with those posted on the web (you will know in this way how you would have done, aiding in your study for the final). I will post the answers to midterm exams promptly after giving them; you will be able to pick up your test booklet in recitation to know how well you did. Bring a #2 pencil with you to exams!
The University of Colorado does not allow me to award even the best of you with an "A+," hence there is (unfortunately) little incentive to really learn the material of any course, in particular this one. To overcome this difficulty--since I believe in creating an incentive to excel--I let anyone with an adjusted 98 or higher average on the two midterms out of the final! [Note: even if you personally do not get out of the final, you should cheer for those that do, since the median will be lower on the final, causing more points to get added to everyone's score on this important test!]. I do require that those getting out of the final continue coming to class for the remainder of the semester. NOTE: the first midterm is nearly half-way through the course and second midterm comes very late in the course (week before the last week of classes); this is to be sure that those getting out of the final are tested over most of the material. The test dates are indicated in the brief course topic description below.
I view attendance at both my lectures and the recitation sections as highly desirable, but do not believe in penalizing those who feel otherwise. Yet those who attend and perform well in recitation always want to feel that they are rewarded for doing so. The way I handle this is to make the TA portion of the grade determine the grades of those on the "margin." The TAs will be, by any system they view as fair and appropriate, assigning one of three grades to your recitation performance in roughly equal proportions: +, 0, or -. If you are on the margin (see below) the + moves you up, the minus moves you down, and the 0 does neither. That is, you can have an 89 (normally a B+) and get either an A-, a B, or stay at a B+; similarly, you could have a 91 (normally an A-) and get either an A, a B+, or stay at an A-. As you can see, there may be substantial advantages to attending recitation and striving in it--however, if you are think you know better how to allocate your time than I do (a reasonable proposition, incidentally), you can be a risk-taker and "blow off" recitation entirely. If you get a 93 you get the A; an 87 gets you a B; that is, you are not harmed, if you are not "on the margin," by deciding not to go to recitation. Similarly, if you are not on the margin, a high recitation grade does not help you. Only if you are on the margin does the recitation grade impact you. Thus, we come to the final course grade calculation:
Highest Average "Score"
100-92 = A (and >98 average on the 2 midterms, exempt from final)
90-92 = A if + in recitation, A- if neutral, B+ if -
88-90 = A- if + in recitation, B+ if neutral, B if -
82-88 = B (not "on the margin" so the recitation grade does not enter)
80-82 = B if + in recitation, B- if neutral, C+ if -
ETC. (basically adjusted 90-100 is A, 80-90 is B, 70-80 is C, 60-70 is D, and below 60 is F, subject to the recitation grade which may or may not have an impact as explained above)
(NOTE: THE PRECEDING COMPLETELY DETERMINES YOUR
GRADE--THERE
IS
NO "EXTRA CREDIT," ETC.)
Brief Course Outline and Reading Assignments (not a substitute for class notes--see the web for guidance and read your book--it is really quite a fun book!).
A CHECKLIST OF HOW TO DO WELL IN THIS (or any) COURSE:
1) How much time do you invest in this course?
[The average student who does not naturally take to economics but still
gets a grade of B or better spends nine hours outside of the
classroom].
2) Do you come to class? [This is more
valuable
than is the case for some courses...anecdotes make the material more
understandable].
3) Do you come prepared? [Stay current.
If you are studying Chapter 3 when the lecture is on Chapter 6, it will
harm your performance. While not needing perfection, do the best
you can to have read the material being covered in lecture].
4) When do you study for this class? [Break
up your study time, to keep it fresh. Don't study when you are
tired].
5) How do you study? [Study by doing.
Work problems, like in physics, chemistry, or engineering. Go
back
and forth between problems, examples, and text].
6) Do you work for understanding? [When you
get a problem right, sometimes by trial and error, go back over the
problem
and see why the method you employed worked].
7) Can you explain it to others? [If you can
explain it to others, perhaps in a study group, you will really
know it].
8) Have you worked on your self-confidence?
[Before you look up the answer to a question, assign a "confidence
factor"
to your work...on a scale of 1-10 how confident are you that you are
right?
Be honest with yourself. The more often you prove yourself right,
the less test anxiety you will have].
9) Do you cram for tests? [Don't. It
will not work in economics, and perhaps not in any analytical
field.
Study regularly, with greater review being the only difference in your
study habits prior to a test. Cramming for tests leads t fatigue,
test anxiety, and stupid mistakes. Get plenty of sleep.
Treat
being in school as having a full-time job...put in your time regularly
and you won't need or want to cram].
A rough guide to topics we will cover (see the website "printable" handout for detailed lecture guides and for specific readings tied to lecture notes):
I. ECONOMIC WAY OF THINKING--HOW DOES THE WORLD "WORK?"
What is "economics?" How people make decisions
made
necessary by the fact of scarcity--Principles:
*people face tradeoffs,
*opportunity costs are only relevant cost concept,
*rational people think "at the margin," and
*people respond to incentives.
How people interact--Principles:
*trade generally makes everyone better off (trade creates wealth, and
is voluntary),
*markets have desirable properties,
*government can sometimes--though more rarely than most people
realize--improve
on market outcomes.
How the economy as a whole works--Principles:
*income and output are identical,
*too much money causes inflation,
*unforeseen policies can affect the economy in the short run.
Science, "realism," and models. Logical pitfalls
(fallacy of composition, post hoc ergo propter hoc, wishful thinking
and
secondary effects or law of unintended consequences). Scarcity implies
choice which, in turn, implies opportunity costs. The "market" as one
means
of solving problems stemming from scarcity (spontaneous order versus
hierarchy).
The central economic questions we will examine are What, How, For Whom,
(and When)? Consumer and firm goals and the spontaneous coordination
provided
by the competitive market. Property rights and incentives. Positive and
normative economics (benefits and costs and their distribution).
Efficiency
(Pareto, Kaldar) and equity. Why economists disagree (theory,
estimates,
and values). The gains from trade and comparative advantage.
Introductory
illustrations: Determinants of the number of children to have, minimum
wages, progressive income taxation, international trade. Graphs:
production
possibility frontier and circular flow. Philosophical issues (What is
"value?").
II. DEMAND AND SUPPLY--THE BASICS
Demand, Supply, and Market Equilibrium (maximizing and coordinating). The "shifts" versus "movements along" confusion clarified. From individual to market demand. Price controls. Elasticity. Government policy applications (farm policy, rent controls, minimum wages, tax incidence, prohibition of goods). One reason why some don't like supply and demand. Intertemporal resource allocation and the price system: interest, compounding, discounting and the role of entrepreneurs and speculators.
III. DEMAND AND SUPPLY--EFFICIENCY AND WELFARE
Consumer surplus, producer surplus, and the gains from voluntary trade. Demand curve as willingness-to-pay. Supply curve as marginal cost, hence willingness-to-sell. Consumer surplus and the paradox of value. A rationale for income transfers? Application: Incidence and welfare cost of taxation. Application: International trade. Theory of comparative advantage. S&D analysis of trade and tariffs. Developing countries. Exchange rates and the international financial system (probably will not get to much on this).
IV. CONSUMER CHOICE AND DEMAND
Note: we will do this material a bit differently from the book. Preference assumptions. Utility and the law of diminishing marginal utility. Rule of rational life. Can consumers do this (animal experiments)?
V. PUBLIC ECONOMICS
Externalities, public goods (including income distribution), common resources, Public choice theory: Will government do better? New theoretical material here (on public goods provision and optimal governmental institutions...not in any book, yet!) The market "wins"--but remember that giving the most of what people want (apart from the public goods problem raised) does not elevate those preferences... Public policy: car regulations, education, housing, cigarettes. Optimal tax systems.
(first midterm--after this material--the date will be voted on in class, with an eye to "optimizing" the date selected)
VI. PRODUCER CHOICE AND SUPPLY
Introduction: Business organization. The
production
function, marginal products, and the law of diminishing marginal
product.
Time periods. Costs: Fixed, Variable, Total, Average, and Marginal.
A. The firm in perfect competition and
supply.
The abstract model assumptions. Three cases: profits, losses,
shut-down.
Market supply. Time periods, again. Efficiency versus equity again.
B. The monopoly firm: definition and bases.
When marginal revenue is not equal to price. Equity and efficiency
implications
fo monopoly and public policy (regulation). Price discrimination.
C. Other market structures--oligopoly and
monopolistic competition (we will go light on this--see class notes)
(second midterm--rather late in course--will also be voted on, but usually in the 2nd week prior to the end of the semester)
VII. INPUT MARKETS, INCOME DISTRIBUTION, SOCIAL ISSUES
Marginal productivity theory. Compensating differentials. Discrimination. Human capital. Land, natural resources, and "economic rent." Capital, interest, and profits. Inequality and poverty. Environmental and international trade issues.
(Final exam: Tuesday December 18th, 10:30am-1:00pm, in our regular classroom)
