From reading this page, I understand that questions about economics not related to personal finance is out of topic here (for example questions about corporate or government finance). Is there any Stack Exchange site where this would be on topic?
https://politics.stackexchange.com/ would be a good place to ask these kind of questions. They have an "economy" tag that should come in handy here.
There was a StackExchange site for economics. But alas, it didn't make it out of beta.
The beta https://quant.stackexchange.com/ Should also be a good option, it's about Quantitative Finance, but in order to understand that you'll need to know a lot of economics as well. For questions about Corporate or government Finance I'd opt for this StackExchange.
