x2), it is relatively easy to draw the indifference curves: you just plot all the points (xl, x2) such that u(xl, x2) equals a constant. In mathematics, the set of all (xl, x2) such that u(xl, 5 2 ) equals a constant is called a level set. For each different value of the constant, you get a different indifference curve. EXAMPLE: Indifference Curves from Utility Suppose that the utility function is given by: u(x1, x2) = ~ 1 x 2What . do the indifference curves look like? 60 UTILITY (Ch. 4) We

increase in utility from the small change d z l , and the second term measures the increase in utility from the small change dxz. We want to pick these changes so that the total change in utility, d u , is zero. Solving for dxzldxl gives us dx2 - d u ( x 1 ,x 2 ) l a x i dx i d u ( x i ,x z ) / a x z ' which is just the calculus analog of equation (4.1) in the text. As for the second method, we now think of the indifference curve as being described by a function x2(x1). That is, for each value of

been 128 REVEALED PREFERENCE (Ch. 7) chosen when the consumer actually chose observation 1 and vice versa. This is a violation of the Weak Axiom of Revealed Preference. We can conclude that the data depicted in Tables 7.1 and 7.2 could not be generated by a consumer with stable preferences who was always choosing the best things he or she could afford. 7.6 The Strong Axiom of Revealed Preference The Weak Axiom of Revealed Preference described in the last section gives us an observable

rented at a given price p* will just be the number of people who have a reservation price greater than or equal to p*. For if the market price is p*, then everyone who is willing to pay at least p* for an apartment will want an apartment in the inner ring, and everyone who is not willing to pay p* will choose to live in the outer ring. We can plot these reservation prices in a diagram as in Figure 1.1. Here the price is depicted on the vertical axis and the number of people who are willing to pay
