Two Questions:
- Since Lexicographic preferences are not continuous, is it still appropriate to use $\Bbb{R}^n_+$ to define my coordinate axes when drawing Lexicographic preferences? If not, what should I use instead?
- Since the indifference sets for Lexicographic preferences are singletons, how do I draw them? What's the convention? Will a single point do?
