James Rice of MIT outlines the pros and cons of making ports public facilities rather than single user or dedicated. Flexibility increases. I think the trend toward sharing port space is part of a trend to public-private partnerships and a sharing of benefits more broadly. And it has to do with the expense of infrastructure. We need more players to pick up some of the infrastructure cost. Public financing for it is done.
