Hi,
Are there any scientific studies or empirical evidence on the validity
of McGregor's Theory Y of Management?  I'm already familiar with the
basic tenets of his philosophy and have found only vague commentary on
'problems with the theory', but nothing with any
concrete mathematical or statistical references backing or refuting
it.  His theory is also slightly dated, so I would appreciate modern
interpretations as applied to skilled workforces vs unskilled
(specifically in technology).

Thanks in advance!
