2013-01. Growth versus Level

One of the things I would like to teach you is to avoid common errors. So, from time to time, I will point out an error when I find one. The title in the Financial Post says:Canada’s productivity beats the U.S. for the first time in a long time
Well, it does not. Productivity  GROWTH  was higher in Canada than in the US in the second quarter of 2013, not the level.  As the article correctly says, our productivity lags behind US.
A similar mistake would be to write that Sierra Leone is richer than Canada.  Last year Sierra Leone's GDP grew by over 15%; much faster than Canada's. But per capita GDP in Sierra Leone is 25 times lower.
Lesson - do not mistake growth rate and level.
