Bruce,

This is a good initiative.

I can tell you in Australia het is taught at 14 eco depts at u/g 
level. I could name them if you wished. I do not have the figures for 
graduate level studies.

In Australia two web sites celebrating het are being set up one by 
Greg Moore at Notre Dame and one on behalf of the history of eco 
thought society of Australia which publishes the history of economics 
review. I presume you are a subscriber. If not, let me know. The 
other web site set up by Greg is a celebration of Australain pioneers in HET

Cheers

Alex Millmow
