New economic make up

As part of the REconomy project we've been looking at the understanding what a new Transition-ed economy might look like. It's got me thinking; going forward money as we know it will be used a lot less (assumed by me as a given)  – a massive part of the economy will be replaced and i wanted to get a feel for what people thought the new economic breakdown might look like and if there are any interesting / leading thinkers on this subject.

Here's a kind of crude breakdown, figures that i've just picked out of the air, that will hopefully kick start some thoughts;

Current economy (100%)

Pure reduction in economic consumption (-30%)

Sharing, which leads to further reduced consumption (-20%) (some of which is localised sharing of physical stuff and some of which is knowledge sharing unbound by locality)

Therefore reducing all consumption & economic activity by 50% at which point we reach an overall steady state economy with different elements of the economy either growing or receeding. Notably this doesn't include the reduction in value of stuff, which i'm ignoring here.

Of the remaining 50% economic activity it will consist of

Local exchange (15%) i.e. non-monetary

Broadly termed as monetary economics (35%) of which some is

Local currencies with little of no national value (20%)

National/internationally accepted currencies (15%)

or perhaps all local currencies but with ways of feeding into the wider network of currencies?

Thoughts welcome
