ACTIVITIES

Lecture/Discussion: all those cost curves & the production function.

Assignments:

Take notes. Click here for the PowerPoint we covered today in class.

(Optional) Complete another production function, similar to the one we did in class.

Click here to open a Microsoft Excel version. You must have Excel on your computer to do this, but it will allow you to use formulas to fill in the cells. See the solution in Excel format.

Click here to open an html (Web page) version of the same document. See the solution in html format.Please note: This is the most difficult chapter in the book. The authors are laying the groundwork for developing an understanding the decision-making in the various types of market structures. The information presented here is therefore foundational for understanding the material in the next several chapters. And this "theory of the firm" is the largest portion of the A.P. Microeconomics test.

ASSESSMENT PROCEDURES

Monitor and adjust as necessary.
