Marginal Revolution
is co-written by Professors Tyler Cowen and Alex Tabarrok. Tyler Cowen is professor of economics at George Mason University and at the Center for the Study of Public Choice, and Director of the James Buchanan Center and the Mercatus Center in Fairfax, Virginia. Alex Tabarrok is associate professor of economics at George Mason University, research director for The Independent Institute and a research fellow with the Mercatus Center. Marginal Revolution is lively, stimulating and well-written. It covers current events, economic policy, links to other economics blogs and quick thoughts on practically anything ("A woman's genetic make-up accounts for at least a third of her ability to climax during sex, say researchers"). Posts, which often quote views of other economics bloggers, are short, readable and light on academic jargon. And there's humor: in a discussion of how to reform economics graduate education, Tyler Cowen concludes that "My recipe for George Mason, my own school, is different. Most of the graduate students simply need to work harder." Launched in March 2005, multiple posts per day, good categorization of articles.

Media Stock Blog
covers media stocks, including movie distributors (such as video rental companies), movie studios, satellite radio, TV producers and newspaper stocks. It's written by David Strahlberg, a sell-side analyst and ex-investment banker, and is part of the Seeking Alpha network of stock sector blogs. (The others are The China Stock Blog and The Internet Stock Blog.) Posts are frequent (often 3 or 4 per day), and the blog is particularly strong in movie-related news. Like its sister sites The Internet Stock Blog and The China Stock Blog, The Media Stock Blog categorizes every post under sub-sector and ticker, making it easy to research any particular stock. And like those sites, it also has deeper coverage of small and micro-cap stocks than the larger financial news sites. The Media Stock Blog is part of the Seeking Alpha Network, run by the author of this page.

Topics include top management team issues, restructuring, financial reporting, firm reputation, and shareholder influence.
