"will more" vs " will be more"

Why "will more" is used in the sentences below instead of "will be more"?
Is "will more" a dialect spoken locally in America?
Do they make any difference in meaning?
Will the meanings remain unchanged If I replace "will more" with "will be more" in the below sentences?

A). Internet advertising in the US will more than double to US$50.3 billion in 2011 from $21.7 billion last year, driven by technology investments, according to a study by research firm Yankee Group.

B).Trends further ahead are typically harder to predict. Still, the Pew Center projects that in 2050, 19 percent of Americans will be foreign-born; that the share of Hispanic residents will more than double to 29 percent from 14 percent in 2005; and that the proportion of Asians will almost double, from 5 percent to 9 percent.

Your advice will be very much appreciated!

Both are  will "more than double" = the sum/figure will increase to more than twice its present level

Thank you

Mr Wordy

In both cases "double" is a verb, so "will more than double" is correct and "will be more than double" is wrong.

In sentences where "double" is a noun, "will be more than double" is correct. For example: If we go back next week then the prices will be more than double what they are today.

You can also make a passive construction, but then you need "doubled": Turnover will be more than doubled, to $50 billion (though this sentence is slightly ugly IMO; normally I would just say Turnover will double...).

Dear Mr Wordy,
Thank you so much for the clear explanation and easy-to-understand examples.
Thank you one more time!

B). Can "will more than double" be replaced by "will be more than double" in the phrase as it's not followed by "to"? No.

C). Has the writer dropped the "be" inhabitually? The writer is correct.  Nothing unusual here.

D). Or, shall I consider both cases are grammatically correct?  No.

to is not necessary.  double is still a verb even without to. 

Revenue = $100,000

If something doubles revenue, it makes revenue = $200,000.

If something triples revenue, it makes revenue = $300,000.

If something more than doubles revenue, it makes revenue > $200,000.

If something more than triples revenue, it makes revenue > $300,000.

But something can double revenue to $200,000.

And something can more than double revenue to $285,000.

Something may not quite double revenue to $195,000.

In addition to doubling revenue, factors may double prices, may double costs, may double payments, may double growth, etc.
