Becoming influential

The Economist has a long article on “economics in the blogoshere”:

From his perch on America’s periphery, Mr Mosler champions a doctrine on the edge of economics: neo-chartalism, sometimes called “Modern Monetary Theory”. The neo-chartalists believe that because paper currency is a creature of the state, governments enjoy more financial freedom than they recognise. The fiscal authorities are free to spend whatever is required to revive their economies and restore employment. They can spend without first collecting taxes; they can borrow without fear of default. Budget-makers need not cower before the bond-market vigilantes. In fact, they need not bother with bond markets at all.

The neo-chartalists are not the only people telling governments mired in the aftermath of the global financial crisis that they could make things better if they would shed old inhibitions. “Market monetarists” favour more audacity in the monetary realm. Tight money caused America’s Great Recession, they argue, and easy money can end it. They do not think the federal government can or should rescue the economy, because they believe the Federal Reserve can.

The “Austrian” school of economics, which traces its roots to 19th-century Vienna, is more sternly pre-Freudian: more inhibition, not less, is its prescription. Its adherents believe that part of the economy’s suffering is necessary, an inevitable consequence of past excesses. They do not think the Federal Reserve can rescue the economy. They seek instead to rescue the economy from the Fed.

Economics, perhaps more than any other discipline, has taken to blogs with gusto. Mainstream figures such as Paul Krugman and Greg Mankiw have commanded large online audiences for years, audiences which include many of their peers. But the crisis has made the academic establishment fractious and vulnerable. Highly credentialed economists now publicly mock each other’s ignorance and foolishness. That has created an opening for the less decorated members of the guild, and the truly peripheral.

The clearest example of the power of blogging as a way of getting fringe ideas noticed is “The Money Illusion”, a blog by Scott Sumner of Bentley University, in Waltham, Massachusetts. In the wake of the financial crisis Mr Sumner, a proponent of market monetarism, felt he had something to say, but no great hope of being heard.

“Austrians” have been around for ages, “Neo Chartalists” sound too much like “charlatans”. I´ll bet on “Market Monetarism” as the new “influential idea”.
