The article talks about how transaction costs can change the way companies think about ownership and investments. When transaction costs are considered, it can be better for a company if one party doesn't invest but still owns something. Also, joint ownership can be the best way to go.

Joint ownership can lead to bigger gains, making it worth the extra costs. In this view, what works best might not be what you'd expect.
