Allocative Efficiency and Competitive Equilibrium
Efficient Distribution of Outputs among Households
We all know that people have different tastes and preferences and that they will buy very different things in very different combinations. As long as everyone shops freely in the same markets, no redistribution of final outputs among people will make them better off.

Free and open markets are essential to this result.
