Ethics Focus Cluster?

<p>Hi, I am attending Duke next fall and would like some advice concerning the best FOCUS program for my specific interests.
First off, I am going to be majoring in Econ/Math. I am very interested in economics and the obvious choice among the FOCUS programs would be Modeling in Economic & Social Sciences.
But, I am also very interested in Ethics, Leadership, & Global Citizenship at the Kenan Institute.
Is it wise to diversify by interest in economics with other things I am interested like corporate/business/govt. ethics?
Will I be at any disadvantage if I takle the Ethics cluster instead of the Modeling in Economic & Social Sciences cluster? (eg: course requirements, economics course, major-relevant knowledge)
Any advantages to taking the Ethics cluster?
What do you do in ethics cluster?</p>
