Blogging has taken the economics profession by storm and turned many aspects of it on its head. Most blog posts are still written in a less than academic fashion. Economists originally communicated with each other via books, and once economic journals were started, through those. Economic journals are still the primary way that serious economists advance their ideas and communicate with one another in a serious fashion. Blogging may one day replace these as the internet has forced new commercial realities on most media formats, but for now journals articles are what economic careers are based on. These are some important economic journals:
American Economic Review
Econometrica
Journal of Political Economy
Journal of Money Credit and Banking
Quarterly Journal of Economics
All of these and many others have been archived digitally on JSTOR.
Many Journal articles originate as working papers which are another primary source of communication by serious economists. One of the most frequent and prestigious publishers of working papers is the National Bureau of Economic Research, but most think tanks, universities, and other institutions also publish them as well. Many Professors publish them on their academic websites.
