(a) to check for completeness we need to observe whether the observations are establishing relationship between each and every element or not.
transitivity can be understood through an example: when a is preferred over b, and b is preferred over c then a should be preferred over c. In the case of preference relation it can also be seen as is a is chosen over b then b can't be chosen over a in other set of observation.
(b) for this, we have to observe previous observations
2. T he set of alternatives is Z-\a,b,c,d,e,f,gj. It has been observed that, when the available...
1. Recall that, for a set of alternatives X, a choice structure is a pair (B,C), where B be a collection of subsets of X and C is a function defined on 'B. with C(B) CB for each B E B. C(B) is the set of alternatives chosen when the budget set is B. In the following examples, X = {a,b,c}. (a) State in each of the three cases whether the Weak Axiom of Re- vealed Preferences holds.
