Grad school: Industrial Engineering or Economics?

<p>I'm going to be a junior next fall and I figure it's too late to change my major (applied math) but I am looking at grad school as an option. Does anyone have any stories about these two fields or opinions about which one is more fun/more useful/etc.?</p>

<p>INDUSTRIAL ENGINEERING!!!</p>

<p>Reason: I'm an engineer haha</p>

<p>What's wrong with math?</p>
