# What would be the practicality of a widespread open-source approach in an economy?

I'm not sure how to tag this so feel free to add any tags you see as relevant.

The question here is about anything that uses a proprietary approach today and applying open-sourcing to it.

What if someone open-sourced their work in such a way that it can be used by absolutely anyone on condition they put a bit of money in to keep a project going?

This instead of intellectual property or copyright sometimes heavily restricting usage and where there is not necessarily a benefit to the community.

Hope you get the gist and please comment below for me to clarify if necessary.

• This seems very speculative and hence opinion based. – Giskard Sep 1 '16 at 21:15
• You would also need to clarifiy what you mean by putting in a bit of money. If I make an awesome open-source software where does the money go? If someone further develops it does that count as putting in money? (They put valuable time and effort in instead.) – Giskard Sep 1 '16 at 21:16
• To clarify businesses could, say, pay the services of a co-op if there is more than one person working on a project. Time and effort is obviously a contribution in itself and that's why open-source shouldn't be considered as free. – James P. Sep 1 '16 at 22:27
• So for an old school response, look at Romer's endogenous growth model - that would say that if everyone was forced to do open source, innovation would likely get hurt. – VCG Sep 1 '16 at 22:30
• Will do. Is there thought the other way? As in the proprietary being detrimental? As in patent trolls for example. Maybe a middle ground is possible. – James P. Sep 1 '16 at 22:32

So suppose there is new technology $A$ that only 1 person has access to. If there are multiple firms with production technology $y=k^\alpha$ then obviously if that new technology was available to them at low/no cost, the overall productivity of society would increase (each firm has $y=Ak^\alpha$)
The problem is that it is likely the case that $A$ requires expenditure to make. You need some way to incentivize the production of that technology (at least in a basic neoclassical framework). So if you make it proprietary then the other firms may have to pay for it, or you can give it copyright so that only 1 firm has access to it.
