This is not the type of volatile monetary policy that Europe wants or needs.

There has been surprisingly little comparative analysis of the effects of quantitative easing (QE) in Japan, the US, and Britain.

A new era of active and varied monetary policy may have begun, with potential benefits for all.

This latest round of monetary tightening in China reflects the authorities growing concern over liquidity. In 2009, M2 money supply (a key indicator used to forecast inflation) increased by 27 year on year, and credit expanded by 34 .

The IMF s Lending Overhaul

Among emerging economies, China could face a hard landing by late 2014 if critical structural reforms are postponed, and the other BRICs need to turn away from state capitalism.

In Britain, economic growth is even slower, while inflation is much higher. And these countries QE has also fueled asset bubbles in the world economy.

The eurozone and the UK remain mired in recessions made worse by tight monetary and fiscal policies.

And these countries QE has also fueled asset bubbles in the world economy.

The combination of loose fiscal policy and tight monetary policy will mean high interest rates, sluggish investment, and slow growth.

This undermines the potency of monetary policy notwithstanding bold and imaginative efforts by the Bank of Japan to inject liquidity into the economy.

That is true of both monetary and fiscal policy the two mainstays of modern countercyclical stabilization.

The experience of the Great Depression led Keynes and his more orthodox successors to greatly underestimate the role and influence of monetary policy.

The first option, a sharp weakening of the euro, is unlikely, as Germany is strong and the ECB is not aggressively easing monetary policy.

First, in the absence of a single global central banking authority, a modicum of monetary policy coordination among major economies is required.

Prior to the crisis, asset price cycles were seen by many as basically harmless or, at least, as a relatively insignificant monetary policy channel.

The ECB s supervisory role will be fully separated from its monetary policy responsibilities.

One argument emphasizes the links between fiscal and monetary policy.

Recent moves to ease monetary policy have been a step in the right direction but, so far, they have not proved to be a game changer.

Can models without an explicit, well developed financial sector be expected to explain an economic world in which financial markets play an ever increasing role? How could central banks, which depend on these financial markets to serve as the transmission mechanism of monetary policy, possibly rely on such models?

Consider the European Central Bank's announcement in January that it would implement quantitative easing.

Unfortunately, that is not how monetary policy works QE will not be enough, and no one should be naive about that.

And, though monetary tightening may well be advisable in some economies, it might be inappropriate in others.

How could central banks, which depend on these financial markets to serve as the transmission mechanism of monetary policy, possibly rely on such models?

One result of this global monetary policy activism has been a rebellion among pseudo economists and market hacks in recent years.

But its composition is different from that of the MPC, so its view on a particular policy stance may be different as well, and here, too, the governor has only one vote.
