Google and Average Revenue Product of Labour

Google’s headcount quadrupled between 2005 and 2009 but for some years the revenue per employee was in decline. This is now in reverse and income from each worked employed is now at a 3-year high at just over $300,000 a year! I might use this chart as a teaching aid when teaching labour market economics - Google is perhaps the world’s biggest advertising agency and it finds even more ways to monetise its services from month to month - whilst keeping the bulk of core functions free to users.
