Thanks for the links, but I guess I misunderstood you. Do you want me to write the article by myself, or to help you guys out? 
What we did in Economy of Mexico was that several users and me elaborated an outline in the Talk page. I'd suggest you guys do the same thing, since you are from Brazil, you'd have some idea of which topics are relevant (say, agriculture, Mercosur, the car industry, whatever). Then, try to find out which links would work for which topics, and try to see if you can actually extract information from the links. Say, for example, if you are interested in Brazil's current account, try to find whether Banco do Brasil is actually reporting the current account. If it does, then add the link, and we can then extract the information later, and start writing the article. See what I mean? Lack of links is not a problem, it is the design, organization and extraction of information what will take some time. "
