Monetary Policy ineffective?

As IB students move to looking at macroeconomic policy I will provide some articles that highlight some recent issues and also help give context to the importance of understanding the theory of policy is important to understanding its use in reality.

The article below makes lots of points. It talks about how the Australian Treasurer (Finance Minister) believes that Monetary Policy has become ineffective in boosting economic activity at present. It also talks about how Fiscal and Supply-side policy must work together to achieve macroeconomic goals.

I am going to concentrate on monetary policy here. Morrison asserts that further interest rate cuts (Australian interest rates have fallen from 4.75% to 1.5% since 2012) will do nothing to stimulate the economy. This is suggesting that the transmission mechanism by which lower rates stimulate economic activity and raise the price level has stopped working.

The theory, which you will learn, suggests that lowering interest rates will raise Consumer and Investment spending and probably Net Exports, all components of Aggregate Demand. However when interest rates are very low many believe that the incentives to change behaviour cease to be significant. If coupled with lower consumer and business confidence even negative interest rates cannot help stimulate the economy on their own.

This is very much a current policy debate. Similar arguments are being had in Japan and Europe where the central banks not only set negative rates but are printing money to try to stimulate the economy.

Notice Morrison's use to the phrase 'pushing on a piece of string' - a classic term used to describe how lowering interest rates does nothing to solve a recession. The answer is more government spending and infrastructure investment. Of course that policy will be cheaper to finance when interest rates are low - so maybe low rates still have a role.

The Age covers the story here

Note that there is a lot of politics in this. Morrison, for example, refuses to acknowledge that more government spending is needed because the political priority is to cut spending to 'solve' the budget deficit. 

There are lots of articles on this argument - look for them for your IA.
