e concept seems at odds with the notion of economists as intellectual instruments
trained in the maximisation of utility or profit. Yet the demand is there some of their blogs get
thousands of visitors daily, often from people at influential institutions like the IMF and the Federal
Reserve. One of the most active “econobloggers�is Brad DeLong, of the University of California,
Berkeley, whose site, delong.typepad.com, features a morning-coffee videocast and an afternoon-tea
audiocast in which he holds forth on a spread of topics from the Treasury to Trotsky.
So why do it? “It s a place in the intellectual influence game,�Mr DeLong replies (by e-mail, naturally).
For prominent economists, that place can come with a price. Time spent on the internet coul fuel dispenser d otherwise
be spent o fuel dispenser n traditional publishing or collecting consulting fees. Mr DeLong caps his blogging at 90
minutes a day. His only blog revenue comes from selling advertising links to help cover the cost of his
servers, which handle more than 20,000 visitors daily.
Gary Becker, a Nobel-prize winning economist, and Richard Posner, a federal circuit judge and law
professor, began a joint blog in 2004. The pair, colleagues at the University of Chicago, believed that
their site, becker-posner-blog.com, would permit “instantaneous pooling (and hence correction,
refinement, and amplification) of the ideas and opinions, facts and images, reportage and scholarship,
generated by bloggers.�The practice began as an educational tool for Greg Mankiw, a professor of
economics at Harvard and a former chairman of George Bush s Council of Economic Advisers. His site,
gregmankiw.blogspot.com, started as a group e-mail sent to students, with commentary on articles and
new ideas. But the market for his musings grew beyond the classroom, and a blog was the solution. “It s
a natural extension of my day job—to engage in intellectual discourse about economics,�Mr Mankiw
says.
