An estimated 400 to 600 million people worldwide are squatters, living on land to which they have no title, usually on the outskirts of cities. Peruvian economist Hernando de Soto has shown that the growth of squatting was due to legal systems that made it very expensive and took years to title and transfer property. He persuaded Peru to undertake what has become the world’s largest titling program.
In addition to turning land into transferable capital, titling may have other economic benefits. Princeton University economics student Erica Field asked whether the former squatters increased their labour output as a result. The theory is that those without titles must remain at their properties to protect them from intruders, while residents with legal title are freed up to pursue work in the community.
Interestingly, although the overall hours worked increased, the amount of labour supplied by children was 27 percent lower for families that were initially squatting in neighbourhoods that introduced title reform early.
