Hello students, the weak axioms of revealed preference i .e.
00:06
Rap states that if bundle a is chosen then bundle b is available and bundle b is no more expensive than a.
00:14
Then a cannot be revealed and referred to b.
00:17
The algebraic statement of rap can be expressed as if pj x j is greater than equal to pj yj and pj yj is greater than equal to pj yj.
00:48
Now, let's apply rap to given data.
00:52
So, first one is if is bundle 0 revealed preferred to bundle 1 and 1 revealed preferred to 0.
00:59
So, pj 0 and x0 that is equal to 1 into 12 plus 1 into 12 plus 1 into 12 that is equal to 36 and p1 x1 that is 1 into 5 plus 1 into 19 plus 1 into 9 that is 33.
01:16
So, p0 x0 is greater than equal to p1 x1 but not other way around.
01:24
Therefore, bundle 0 is not revealed preferred to bundle 1 and bundle 1 is revealed preferred to bundle 0.
01:32
Now, is bundle 1 revealed preferred to bundle 2...
