Document Summary

Suppose we observe the demands (consumption choices) that a consumer makes for different budgets. This reveals information about the consumer"s preferences. We can use this information to Test the behavioral hypothesis that a consumer chooses the most preferred bundle from those available. Do not change while the choice data are gathered. Together, (strict) convexity and monotonicity imply that the most preferred affordable bundle is unique. If preferences are convex and monotonic (i. e. well-behaved) then the most preferred affordable bundle is unique. Suppose that the bundle x* is chosen when the bundle y is affordable. Then x* is revealed directly as preferred to y (otherwise y would have been chosen). x1 x1. The chosen bundle x* is revealed directly as preferred to the bundles y and z. x* z y x1. Suppose x is revealed directly preferred to y, and y is revealed directly preferred to z. Then, by transitivity, x is revealed indirectly as preferred to z.

Question 2

In which of the following situations would reliance on expert opinion as a basis for a managerial decision be most preferred?
