We study a fundamental institution in many societies: the structure of property rights over land. Across societies, communal land rights have been more common than private land rights. We test the hypothesis that longer fallow requirements - the time needed to leave land uncultivated to restore...

How do the different elements in the standard bundle of property rights - such as the right of possession or the right of transfer - differentially impact outcomes, such as urban development? This paper incorporates insecure property rights into a standard model of urban land prices and density,...

We examine the origins, persistence, and economic consequences of institutional structures of agricultural production. We compare farms in the Argentine Pampas and US Midwest, regions of similar potential input and output mixes. The focus is on 1910-1914, during the international grain trade...

We study the innovation and diffusion of technology at the industry level. We derive the full dynamic paths of an industry's evolution, from birth to its maturity, and we characterize the impact of diffusion on the incentive to innovate. The model implies that protection of innovators should be...

In this paper we propose a theory of optimal property rights in a financial contracting setting. Following recent contributions in the property law literature, we emphasize the distinction between contractual rights, that are only enforceable against the parties themselves, and property rights,...

Property rights are the most fundamental institution in any society. They determine who has decision-making authority over assets and who bears the costs and benefits of those decisions. They assign ownership, wealth, political influence, and social standing. They make markets possible; define...

A central challenge in securing property rights is the subversion of justice through legal skill, bribery, or physical force by the strong--the state or its powerful citizens--against the weak. We present evidence that the less educated and poorer citizens in many countries feel their property...

This paper explores a series of general-equilibrium models in which people can choose to be either producers or predators, and in which producers can allocate their resources either to production or to guarding their production against predators. The analysis shows how the ratio of predators to...
