A2 Macro Diagrams

In our revision session today we were discussing which diagrams can be used in A2 macro questions. Here is the initial list we came up with ... can students and teachers suggest more? I will happily put together a powerpoint with the diagrams suggested.

Chart of the Day: UK Shop Prices

There are few signs so far that the fall in the UK exchange rate against the Euro and accelerating inflation in costs and prices in China are yet showing through in the prices we pay for non-food items in the shops.

Deflation in Goods

I have an admission to make. A few weeks ago I inadvertently dropped my digital camera and my Blackberry into a toilet during a rest-stop at Portsmouth FC’s training facility! The camera is now useless but the Blackberry survived intact and working fine!

Having decided to replace the camera I find on Amazon.co.uk that the same make is available for twenty per cent less than at the same time last year and perhaps a good example of the heavy rate of annual price deflation in the prices of household goods in the UK. In part this helps to explain why the official measures of inflation captured by the CPI and RPI remain relatively low despite sharply rising food, fuel and utility bills. But critics of the RPI and CPI calculation retort that few households replace their household goods every year – so price reductions have little direct impact on their annual cost of living. The Times covered this trend in an article in yesterday’s paper.

“According to Pricewaterhouse-Coopers (PwC), the accountants, the prices of everything from a kettle to a camera have tumbled by nearly 50 per cent since the early 1970s…..The biggest price-cuts have come in the past decade, as retailers have taken advantage of improvements in technology, the manufacture of products overseas and, most recently, the depreciation of the dollar against the pound.”

How long can this price deflation last? The pound is falling against the Euro and marking time against the US dollar, there is plenty of evidence of surging cost and price inflation in China and other emerging market countries.

Stephen King savages rigid inflation targets

Stephen King, Chief Global Economist at HSBC is brilliant in today’s Independent - attacking the rigid adherence to an inflation target based solely on the rate of change of consumer prices and ignoring asset price deflation. One of the best comment pieces on macroeconomic policy that I have read in a long time.

“The rigid adherence to an inflation target in a world of constant external shocks may sometimes be more a source of instability than of tranquillity. With sizeable relative price shocks stemming from globalisation, the risks of instability are all the greater. Even worse, if the public thinks that price stability is the only litmus test of economic health, the achievement of low inflation may encourage excessive risk-taking which, in turn, could undermine the achievement of broader economic objectives.”

A to Z of AS Macroeconomics!

Teaching at 5.30pm on a Friday afternoon as the fag end of term approaches isn’t great fun but after a successful SWOT analysis of the UK economy yesterday, I set my AS macro group a half hour challenge today - to produce an A to Z of macroeconomics as a prelude to their revision. Working in pairs, they tried to assemble twenty-six entries - it could be a concept, an issue in the news or perhaps a well known economist - anything so long as it had a macroeconomic connection! Similar to the game of Scattegories, teams only scored a mark when their answer was unique within the class.

Double points could be scored for suggestions such as Ben Bernanke, price pressures or credit crunch. Three marks for purchasing power parity! This led to some very creative and quirky answers.

Anyway ... here is a potted (albeit incomplete) summary of the responses. My job over the weekend is to produce a word document that provides a web link to a newpaper or BBC news story for each of them - so that they can access some articles linked to their suggestions whenever they want to. Can blog users suggest other entries? I am happy to email the word file over if you want to try this exercise before the end of term!

Depreciating lemons and peaches

The prices of used cars are falling faster than ever before.
