-“Potential competition” is super important: current “more likely than not” standard is not right.3/
-Use “expected consumer surplus”. Probability of future competition (with large future gains) can be sufficient to optimally block mergers.4/

-Look at G, but also FB, and MS...
-Super valuable to learn from these studies. 7/
