Article of the Week: The Economist


This article provides useful analysis of another indicator, The Big Mac Index, composed in 1986 by The Economist to help explain Purchasing Power Parity (PPP), look at Word of the Day. Although immense detail of PPP is NOT required in the AQA syllabus, it may be useful to understand more about exchange rates/inflation or merely for those looking to learn more beyond what’s required. Just mentioning it will show the examiner you have that extra knowledge. The article is a good read and explains the need for more ‘out of the box’ thinking for developing better indicators, not just for PPP.

Points to pick out from the article:

·  The Big Mac index has shown that the Euro is overvalued because the local currency against the dollar (measured by the Big Mac index) adjusted for GDP per person is greater than the raw index.

·  The yuan fairs pretty close against the dollar.

·  More sophisticated methods such as PPP requires more information and takes too long to produce, thus the Big Mac Index is a fairly good substitute.

For the charts to help the analysis:
