The Economist who?
I know not of this The Economist, that you speak of :)
Isn't .com US, if this is a UK company why not show some pride and use the .co.uk domain, which some newspaper appears to own but not put any content on.
Google will allow those in the UK to find you better, if you use the .co.uk domain.
And hey, if they really want the domain just make an offer. It has been years, little late to come up with brand infringement. And they are using English words, not some made up brand name, so it muddies the waters even more. If you use a brand strategy that relies on English words, then be proactive and make sure you register the appropriate one's early, it is a double edged sword, sure you get free recognition by jumping on an existing word, but it is harder to keep the brand unique.
