Partial Common Ownership is a compromise between Common Ownership and traditional private ownership.
Partial Common Ownership optimizes Allocation Efficiency and Investment Efficiency at the same time; Common ownership deters Monopoly while private ownership encourages investment.
Together with an understanding of the Texas Shootout, we can say that an individual with x% of stake in a property has x% incentive of a 100% stakeholder, to invest in the property. This is because even if the partnership is dissolved, they are bound to get the value of their investment from the property. This is unlike the Vickerey Commons where your investment incentives are very low.
