Question

Consider the problem from Lecture 4, “Search, Sampling and
Independence.” Assume that the distribution of prices from which
the consumer draws is (i) continuous and (ii) Uniformly distributed
on the interval [ ¯ p, ¯ p]. (a) If the consumer is lost in the
mall and doesn’t remember the last store he visited (i.e. the last
price he drew) and so cannot avoid the possibility of returning to
the same store, are successive price draws dependent or
independent?

(b) If the consumer is lost in the mall and does remember the last
store he visited (i.e. the last price he drew) and so can avoid the
possibility of returning to the same store, are successive price
draws dependent or independent?

(c) Intuitively, why is your answer diﬀerent from the case of the
discrete price distribution?

Answer #1

**solution:**

a)

The consumer is lost in the mall and doesn't remember the last store he visited and cannot avoid the possibility of returning to the same store (i.e. the last price he drew), successive price draws are independent

Since there is probability will not depend on each other in this particular case

b)

the consumer is lost in the mall and doesn’t remember the last store he visited and can avoid the possibility of returning to the same store (i.e. the last price he drew), successive price draws are dependent

Since there is probability will depend on each other in this particular case

c) The answer is different from the case of the discrete price distribution because here the condition cannot/can avoid the possibility of returning to the same store is creating independence/dependence.

The prices are uniformly distributed

During the trial, lawyers for the accused said that the men
believed that the accounting decisions they made were appropriate
at the time, and that the accounting treatment was approved by
Nortel’s auditors from Deloitte & Touche. Judge Marrocco
accepted these arguments. Marrocco added he was “not satisfied
beyond a reasonable doubt” that the trio (i.e., Dunn, Beatty, and
Gollogly) had “deliberately misrepresented” financial results.
Given the facts of the case, do you believe Judge Marrocco’s
decision was justified? Explain....
