Correlation does not equal causation

this study ignores basic economic principles and facts:

- "speculators" are buyers and sellers

- We have a global market.... US Govt price controls have only served to increase domestic prices.

- The premise is that prices are going up because speculators want them to..... if this were true why aren't they going up in every stock or market?

This is an airline political agenda wherein they believe that they should be the only ones allowed to speculate prices (i.e. lock in today's price on futures..i.e. hedging) and no other person (those greedy speculators!!) should be allowed to (as if those buyers are hording millions of barrels of oil in some remote location waiting for the price to go up).
