That is odd that Angus Maddison's "Level of GDP per hour worked" in 1998
differ so much from IMF's "GDP per hour" in 2001. It certainly shouldn't
have changed so much in 3 years.  I think your point about hours worked
is important. Using Maddison's 791 hours and "un-normalizing" the IMF
data on that basis, hours worked per head (Maddison) and "average hours
worked" (IMF) looks like

  ---------------------
  IMF Maddison  country
  ---------------------
  791  791      US
  638  682      UK
  611  637      Italy
  584  580      France
  551  670      Germany
  ---------------------

Maddison's number is 22% higher for Germany, 7% higher for UK, 4% higher
for Italy, and 1% lower for France. IMF does not specify whether the
"average hours worked" is per capita, or per employed worker. Maddison's
numbers are specified as "per head" (per capita), and per employed
worker numbers should be higher than per capita numbers (due to
unemployment). But IMF's numbers are generally LOWER than Maddison's, so
something strange is going on.

Also, Maddison appears to use the logical formula

  GDP per hour = GDP per capita / hours worked per capita

whereas the IMF chart appears to do some correction for "labor force
participation" which isn't clear to me. It looks like IMF's data may
have resulted from some weird manipulation, whereas Maddison's data seem
reasonable to me. (Or the number of hours worked per capita by Germans
went down 22% between 1998 and 2001)
