Provide an example of a positive production externality, either one you have read about or found through research, or one that is hypothetical. The example should clearly state what benefit arises out of the production, and how this benefit without the benefit of market transmission positively impacts other firms. Include in your IP posting a graph for those firms impacted by the positive production externality. For example if firm A produces something that generates a positive production externality for firms B and C – show the impact on firms B and C.
