Ask not what your monetary policy can do for you, but what you can do for your monetary policy. That’s the jist of a 1968 paper by Milton Friedman, the poster-child for monetarist economics, entitled “The Role of Monetary Policy,” whose key questions remain hotly debated more than four decades on. Friedman’s answer is simple (some might argue too simple), and all too familiar to those who read the speeches of present-day Federal Reserve hawks – focus on the only thing monetary policy can truly control, which in Frideman’s view is price stability.
The reality of ‘political economy’ is something that irritates many economists — the “purists”, if you like. The political element is impossible to model; it often flies in the face of textbook economics; and democratic decision-making and backroom horse trading can be notoriously difficult to predict and painfully slow. And political economy is all pervasive in 2010 — Barack Obama’s proposals to rein in the banks is rooted in public outrage; reading China’s monetary and currency policies is like Kremlinology; capital curbs being introduced in Brazil and elsewhere aim to prevent market overshoot; and British budgetary policies are becoming the political football ahead of this spring’s UK election. The list is long, the outcomes uncertain, the market risk high.
