Conceptions of economics: Comment from Dr Doyle

A few weeks ago a fellow named Jeffrey Doyle posted a “history of economic thought” type comment/post on the blog, which can be found here.

Beyond this he also added one additional criticism of “neo-classical economics” – the focus on “monetary flows” instead of energy.  Of course, as a criticism of economic science this is a misnomer – economic science is the study of scarcity, and “monetary flows” are merely a convientent way of representing this scarcity.  Using energy as a representation should – if the models are sufficiently specified – provide the same results.  Now, in when applying models there may be substantial differences, given what is implicitly assumed to be useful or not in different models – while this argument is important for application it is not something I can argue about, as I do not have the scarce intellectual talent to go around and apply a new set of assumptions to an underlying framework of scarcity.

However, my impression is that Dr Doyle is not criticising the individualistic methodological process in economics – he is attacking the “economic unit” used when we study scarcity, something that is constantly occurring and is a healthy part of any discipline.
