A PACK of the most popular cigarettes in the Seychelles in 2008 cost$15 at purchasing-powerparity (PPP), based on data from the latest World Health Organisation (WHO) tobacco report.
The index is based on the idea of purchasing-powerparity (PPP), which says currencies should trade at the rate that makes the price of goods the same in each country.
Yet physical indicators (such as electricity consumption) and the results of income comparisons based on purchasing-powerparity (PPP) suggest that the GDP picture may not be entirely misleading.
