COURSE DESCRIPTION
This course is essentially a course in applied microeconomics. Students should learn the ability to use economic thinking to enhance critical thinking and problem solving skills to improve the efficiency of organizational decision making. In addition, students will become familiar with economic models and technology for quantitative analysis.
COURSE REQUIREMENTS
1. Homework Assignments (up to 20% of grade)
At least 5 homework assignments will be given. Each is worth 5% of your final grade with the credit deducted from your lowest exam score. Homework is optional, but if it is turned in it will be graded and counted (so don't turn in junk). Homework will be assigned one week before due date, and will usually consist of problems from the end of chapters. Homework is important in terms of final grades, and as a preparation for exams. Collaboration with fellow students is allowed, though answers should not be identical. Homework will be graded on a scale of one to ten.
****Under No Circumstances Will Homework Be Accepted Late*******
2. Demand tutorial project (25
percent) See instructions below.
3. Three Exams (up to 75% of Grade)
EXAM 1 25%
EXAM 2 25%
EXAM 3 (final) 25%
Each exam will consist of short answer essay questions and problems.
Makeup exam policy: Makeup exams will only be given for well documented emergencies. In all other cases missed exams will be counted as zeros.
ATTENDANCE
Attendance is strongly suggested. Students are responsible for all material covered during class. If a class is missed you should get copies of the notes from students who were present.

Demand Tutorial Instructions
Construct a Demand tutorial using Microsoft Excel. The tutorial should demonstrate the changes in quantity demanded and changes in demand for a market demand curve estimated from actual data. The assignment should give you the opportunity to review and understand the theoretical relationships underlying the demand curves. In addition, the exercise will require a review of statistics particularly regression, and develop facility with Excel.
1. Construct a theoretic demand model for a commodity of your choice. Make a list of the necessary variables (dependent and independent), and the expected relationship between each independent variable and the dependent variable. Tip: Only try to estimate models where data is available. It does little good to theorize about toothpaste if you cannot find data on toothpaste. Start with an idea that has a chance of working...peruse the available data.. Tip: Price data is harder to come by than quantities. If you have prices you can usually get quantities, but quantities may not be associated with prices. Pick prices first
2. Attempt to estimate the theoretical model using the data from the
2a. collect the relevant data

2.b. Once you have established your data set, estimate the demand relationship and evaluate your success. Was the necessary data available? What variables were missing? Are the signs correct? Are the results significant? Include this information (including your explanation of the theoretical model) in text boxes in the final product. Explanations should be error free.
3. Use the data and the resulting model to construct a tutorial for demand using excel. The tutorial should demonstrate how demand would shift when there is a change in one or more of the independent variables. It should also illustrate marginal revenue and elasticity.
Submit both hard and electronic versions of your analysis. Both versions of submission should be free of grammatical and typographical errors and have a professional appearance
Your evaluation will be based on the following:
Each of the above bullets should correspond to a separate sheet in your workbook.
