Thanks a lot Max, that is helpful ! I am just not so familiar with US sources. To be honest, I am impressed by the quality of presentation of NIPA data sets you refer me to. When I was a Phd student in New Zealand in the 1980s, I had to go on my bicycle to the Stats Dept to get a print-out of the disagggregate data. These days of course people are so much more sophisticated, compare: http://www.stats.govt.nz/domino/external/web/Prod_Serv.nsf/htmldocs/National +Accounts#information
