I've been waiting for this one special report from The Economist quite impatiently ever since I saw the advertisement a couple of weeks ago in the respective issue of the magazine itself. And to my surprise, the whole of the survey is available for free online although this is proned to change. Maybe it's a glitch from their side but even the premium articles, marked by this logo, are free to anybody.
No need to say, I jumped on this rare occasion and I'm currently printing the whole of survey. Althought I will buy this issue as well.
Update (21 April, 19:16): Looks like The Economist did make a mistake. The majority of the articles, forming part of the survey, are in fact Premium articles, that is you need to pay to get access. As I've mentioned earlier, although the logo denoting premium content was placed besides the links to the individual articles, all right, the complete version of the articles were available for free. Unfortunately for you guys, it's no more. Premium content is indeed premium content now. You'll have to buy the issue, I guess.
