Is it me, or am I not able to find any question board regarding economics? My point is, that it would be great with a board were people could ask questions about economics in general, world economics and so on.
"Why is Greece close to a national bankruptcy", "What's the difference between MasterCard and VISA" And so on!
Proposals for new topical Stack Exchange QnA sites are handled via a site called Area 51. I see there is a proposal for an Economics site active there. You can read some about the process and how you can be involved on the Area 51 FAQ page.
Not every subject area is a good candidate for SE style QnA. Of the ones that are, often only a subset of issues related to the field make good questions. Of your two proposed questions, I suggest one of them is good and one of them would probably not fly even on a site dedicated to Economics. Perhaps it would work on a Personal Finance site, but it is kind of a dodgy question.
In order to launch a site, example questions have to be approved that demonstrate the topic could fit under the kind of QnA that SE sites focus on, and several hundred people need to commit to helping get it off the ground.
