(For an explanation of what this page is all about, read the comment at the bottom.)


The Firm and Its Constraints

Dealing with Three Fundamental Tasks
The Production Function

The article in wikipedia will tell you all you want to know about production functions and probably a lot more:

The Demand Curve for Output

Amosweb explains how the demand curve is the source of the marginal-revenue curve:

Summary

Textbooks traditionally show how firms maximize profits using a variety of cost and revenue curves. About.com has a good example of this approach in the form of a problem you can work:

CyberEconomics arose from my dissatisfaction of the standard college economics textbook of the 1960s and 1970. I set out to write a book that would reflect a different way of organizing the course, a way that I thought better reflected the state of economics in the 1970s and 1980s than what I saw in the textbooks. In the years since, other authors have moved towards my organization, and on some topics they have moved past me.

A few years ago I began to question the need for any economics textbook, even mine. With the new technology of the internet, could the textbook as we know it be obsolete? What would a textbook look like if it were composed of bits and pieces that could be assembled from the internet? In the summer of 2007, I decided to find out by composing such a textbook, and this page and the pages like it are the result. However, in making this alternative textbook, I kept the same structure that exists in CyberEconomics. If I were really serious about getting rid of the textbook, I would want a different organization, one that dropped many of the topics from the traditional textbook and went into more depth on a few key remaining ideas. But the cost of that project is too high, given my time, abilities, and alternative opportunities.

I am moderately satisfied with the results. In many cases finding readings that were roughly compatible with topics and coverage of the chapter was difficult. I used a lot of entries from Wikipedia because they seemed better than the alternatives I could find in the limited time given to this endeavor. I found Wikipedia an uneven source: some articles are very good, others are overly technical, and a few are a mess. I also used many entries from The Concise Encyclopedia of Economics even though in many cases they were longer and more detailed that what I really wanted. The temptation to link to the work of the many great economists who have written for The Concise Encyclopedia of Economics was just too great.

Even though this first (summer 2007) version leaves much to be desired, with feedback future editions might develop into something much better. I am especially interested in relatively short readings that have stable urls. Newspaper articles sometimes have stories that illustrate economic concepts in entertaining ways, but finding them is very time consuming, and often they do not have lasting urls. If you have suggestions of sites that are informative, entertaining, and/or interactive, send them to me at schenk at saintjoe.edu.

The reason these sections are called "Alternatives and Supplements" is that they can serve not only as alternative readings, but they can also be used to explore the topics in more depth or from another point of view. I really do not want to make my text obsolete: I am hoping that this new feature will make it more useful, not less useful.
