      You have misinterpreted. I have only one adsense which I linked to my blogs also. The same hubpages Google adsense account. But, I think the earnings are shown separately. The earnings on my blogs are only one dollar as they pay per 1000 views or so. I don't spend in researching. So, I am not confirmed.

      When you click at the website icon on my profile right side corner, you will land into economics blog. Another two links are visible on my economics blog (one is lifestyle tips and other one is my comments blog).

      I have my adsense on my blog also. I enabled it along with hubpages. Then, I disabled it for one month as I my computer was hacked by obscene ads. Recently, I again enabled it after installing adblock plus. Now I do not see any ads at all on my computer.
