Silver Consensus & Grand Tribunal

The 'Harvey inflation' is no longer referenced in Julia Crick, Elisabeth van Houts - A Social History of England 900-1200 - Cambridge University Press 2011, ISBN 978-0-521-71323-8 (see cambridge.org/us/academic/su ... ?format=HB ).

You find there:

So no inflation then.

Of course (see also https://forum.atlas-games.com/t/the-break-room/102/1 ) this was not the state of the art in 1999, when Heirs to Merlin was written. So Heirs to Merlin reacts to 'Harvey inflation' - or its discussion - by having Stonehenge magi cause their own inflation. This shows the research that goes into the ArM books.
Also (see Card & Board Games ARCHIVE & LINKS ) Stonehenge covenants were indeed liable to 'political spending' at the very end of the 12th century, which - if excessive - could well have caused an inflation.
