The instructions for running Mathematica are in Appendix B. We begin by assigning values to the parameters a1 and a2 . In this case we assign the value 1 to both of them. Start Mathematica and on the Untitled-1 window that opens type a1 = 1 followed by Return and then a2 = 1 followed by Shift-Enter Mathematica acts as an interpreter and commands are processed one at a time. When you use Return at the end of the line you effectively ask Mathematica to postpone the processing while you proceed to enter another command on the next line.

You could even use your own data of some kind for doing this. Some students with greater interest in professional sports than in the stock market have used offensive and defensive statistics from basketball teams to predict the point spread in playoffs. Also, you can change the number of input series x1 thru x5 by adding series such as x6 and x7 for other automotive companies such as Toyota and Honda. However, this is somewhat harder to do than the experiments discussed above since it involves making changes in the formulas in the spreadsheet.

4 Cobb-Douglas Function Contour Lines If you are following along with Mathematica, you might close all the files you have opened so far to reduce the clutter on your computer desktop and give yourself a fresh start in the next section. 54 Chapter 3 Partial Equilibrium in Mathematica 3. Consumer Theory The standard theory of consumer’s behavior poses the problem faced by the consumer as one of maximizing utility subject to a budget constraint. That is, given a bundle of goods, their prices and a certain amount of income, the consumer buys those goods according to her preferences while trying to maximize her utility, a quantity that is supposed to measure the level of consumer satisfaction.
