Over the past three decades, Romanian housing rights changed from a strictly managed public stock to one governed by individual decision-making. And while it is typical that widespread private ownership provides a basis for a well-functioning housing market, in Romania this has not been the case. Indeed, rather than creating a market that spontaneously allocates resources efficiently, housing privatization in Romania has created exclusion rights, thus creating an Anti-commons problem. This problem can have effects similar to those of the tragedy of the Commons in which those who share a common good overuse it. In the Anti-commons, in contrast, if too many owners have the right to exclude others from use of a resource, the resource is underused. In both cases, the rights allocation wastes resources.JEL classifications: R31, R32, R38.
