In only the broadest terms. The fact is that there are certain stores that any given single person is never going to walk into. I, for example, am never going to walk into 99% of the stores in any given shopping mall under any circumstances.
The other issue is that when you have a destination store like Apple, if someone buys something there, there is a good chance that Apple has taken all the money that they're going to spend, since (aside from accessories like iPhone cases), the products are expensive. How many people do you think get a new phone, Pad or computer in the Apple Store in a mall and then say, "Oh, while I'm here I think I'll buy some jewelry" or "I also need to buy some shoes." Maybe the pretzel vendor gets a sale.
What other stores might benefit from are the people who go to the Apple store, aren't ready to buy yet and then spend additional time perusing the mall. Those are the people most likely to spend money on something else.
There's a shopping mall in Queens, NY that at one time (and even though it was a crappy mall) had the highest revenue per square foot of any shopping mall in the U.S. (even more than the Mall of America). So they tripled the size of the mall. Total sales only went up slightly. Sales per sq/ft went way down. Why? They're basically splitting the same dollars over more stores.
Next time you're in the mall, look for people carrying Apple bags/products. See if they're carrying bags from any other stores. My bet is that you see that less than 5% of the time.
Of course all this is anecdotal and can't be proven either way unless one can demonstrate that Apple moved into a location, sales went up for the nearby stores, then Apple moved to a different location in the mall and sales went down for those stores. Even that wouldn't be solid proof because of the vagaries of the economy and consumer spending.
