Stanford JD/PhD Economics Student Profile

<p>I'm looking for former/current students to help me on this. Which universities do students in the Stanford JD/PhD Economics program, or plainly the Economics PhD program attend for their undergraduate work? With respect to the admission profile of high GPAs, do students who attend lower tier universities stand better chances at the program? since it's probably easier to get high GPAs in such universities than competitive universities such as Harvard and UC Berkeley.</p>
