The Econlib newsletter is out for August and Anthony de Jasay has a review of the international league ladder on corruption as reported by Transparency International. This looks like a fun way to get at the data.
The list for the year 2010 makes interesting reading. The top ten countries are Denmark, New Zealand, Singapore, Finland, Sweden, Canada, The Netherlands, Australia, Switzerland and Norway. The ten bottom countries down to 178 are Equatorial Guinea, Burundi, Chad, Sudan, Turkmenistan, Uzbekistan, Iraq, Afghanistan and Somalia. The first thing that springs to the eye is that the least corrupt countries are all rich and the most corrupt ones all poor or worse, downright miserable basket cases. [the US came in at 22]
This is old news but the point I want to ponder is the way that Australia rates so high while we know that there is a heap of corruption as a result of the control of the ALP by the trade unions and other factions, not to mention the Greens. Check out the Wonthaggi desal plant, the kind of appointments made by ALP Governments and the serial scandals that have emerged in NSW and Qld.
It would be informative to check out their tools for measurement, but right now I have an appointment. Maybe a commenter can provide a thumbnail.
