The Holdout Problem: “the holdout problem has been defined in many ways. Properly understood, it is a form of monopoly power that potentially arises in the course of land assembly. Once assembly begins, individual owners, knowing their land is essential to the completion of the project, can hold out for prices in excess of their opportunity costs.” http://digitalcommons.uconn.edu/cgi/viewcontent.cgi?article=1151&context=econ_wpapers
Simple English: The holdout problem is basically when someone is trying to build a road or a shopping center or some other such thing, and people refuse to sell their property for a price they’d normally accept because they know the developer will pay more. They’re “holding out” for a higher price. When too many sellers “hold out,” they can collectively push the asking price beyond the developer’s willingness to pay, therefore scuttling the project. The holdout problem is used to support eminent domain.
The Solution: “private developers, who lack the power of eminent domain, have managed to circumvent the holdout problem by concealing the plans for the properties being acquired and by using contingent contracts. For example, a developer who intends to acquire a large number of individual parcels of land for a shopping center will keep his plans a secret, and have others buy the properties for him, one at a time. In addition, the properties will often be purchased with options, giving the developer the right to rescind in the event that all the properties required for the project cannot be acquired for less than a specified amount.” pg. 77, “Economic Foundations of Law,” by Stephen J.
