Course description: Microeconomics is about what goods get produced and sold at what prices. The course builds on the Principles of Microeconomics (Econ 2010-4), doing the material at a more advanced level and stressing strategic issues . Game theory is introduced and the characteristics which determine industrial structure are explored.
The presentation of the course is at the intermediate level. It is required that the student has passed Principles of Microeconomics (Econ 2010-4) and MATH 1050, 1060, 1070, 1080, 1090 and 1100.
Grading: the student's grade will be principally determined by his/her performance in the three exams. A small percentage of the final grade will be determined by performance in a game, and by some data collection exercises to be given out in class.

(
Getting Started on a speadsheet (Quatro Pro)
1. Tum on computer & monitor
-switch is on backside of cpu (box) -switch is on right hand side of monitor
2. press any key when instructed until you get to the MAIN MENU
3. Use mouse or arrow keys to highlight Applications, press enter
4. highlight Quatro Pro, press enter use quatro pro command set, press enter
5. You will get a blue screen with command bar across the top Each square (cell) has an address such as Al (1st column, 1st row) or DlO (4th column, 10th row) You can type words, numbers, or formulas into these.
6. We will go through using an inverse demand function to generate a demand schedule, and graph. example: P=200-Q2
•
7. At Al, type "Example Inverse Demand" and enter.
8. Move to A3, type "Quantity" and enter
9. Move to B3, type "Price" and enter
10. Move to A4, type "l" and use arrow key to move to A5 .
11. At A5 type "+" then move the cursor to A4, then another "+" and "l" and enter. (You've just created a formula which says "take the number in the cell above this one and add 1 to it" . Notice that A5 has a 2 in it but the black line says + A4+ 1.
12. Now copy the formula down. by using the mouse or"/ " to get to the red command bar. Choose
EDIT, and enter COPY, and enter -the black box says-source block of cells: A5 .. A5 press enter or if it doesn't say A5 .. A5 press esc and type it in. -the black box says-destination for cells:
type A6 . . A20 or highlight the cells and press enter
13. Now move the cursor to B4. You want the spreadsheet to calculate the price that corresponds with Q= 1 for your demand function so you type, +200-A4"''2 and enter.
15. Notice that some of the prices are negative so they are outside of the range we are considering so erase them so erase them,
EDIT ERASE BLOCK Block to be modified: A18 .. B20 enter
If you want to print your demand schedule, choose Print Block the block of the spreadsheet to print, type Al .. C20 enter then choose SPREADSHEET PRINT
It will print on the EPSON printer, if you want to print on the laser printer, choose OPTIONS HARDWARE PRINTERS DEFAULT PRINTER SECOND PRINTER QUIT twice. Now when you print it will come out on the HP laser printer
If you want to graph your demand schedule, choose, GRAPH GRAPH TYPE LlNE SERIES XAXIS
x axis labels block: A4 . . Al 7 enter lST SERIES
1st series block: B4 .. Bl 7 enter Quit, then from the Graph Menu choose VIEW
Press enter again when you are done admiring your work. You can add labels to the axes and a title by using the TEXT option on the GRAPH menu
To print your graph, get out to the main menu and choose PRINT GRAPH PRINT GO
Assignment due Friday January 21, 1994: Construct and Print the demand schedule the graph for
P= 500 - (l/2)Q' ie 500- 0.5*QA3 for q= 1 through 10. To Exit, choose FILE, EXIT, yes
