Itzchak Tzachi Raz. Working Paper. “Use It Or Lose It: Adverse Possession and Economic Development”.Abstract
The legal doctrine of adverse possession limits the security of property rights by transferring formal land titles from absentee owners who leave their land idle to adverse possessors that use the land. This paper exploits plausibly exogenous variation in the security of land titles, as a result of historical changes of adverse possession legislation in U.S. states between 1840-1920, to investigate the causal effects of the security of land titles. I find that a reduction in the security of titles increased agricultural output. The main channel is incentivizing higher land utilization. A reduction in the security of land right is also associated with an increase of investment in farms and improved access to capital markets, as well as with an increase in the share of owner-cultivated farms and the number of mid-size farms. These findings suggest that the effect of property rights on economic development is not monotonic, and that property rights may be over secure.

Itzchak Tzachi Raz. In Preparation. “Learning is Caring: An Agrarian Origin of American Individualism”.Abstract
This study examines the historical origins of the American individualism. I test the hypothesis that local heterogeneity of the physical environment limited the ability of farmers on the American frontier to learn from their successful neighbors, turning them into self-reliant and individualistic people. Consistent with this hypothesis, I find that current residents of counties with higher agrarian heterogeneity are more culturally individualistic, less religious, and have weaker family ties. They are also more likely to support economically progressive policies, to have positive attitudes toward immigrants, and to identify with the Democratic Party. Similarly, counties with higher environmental heterogeneity had higher taxes and higher provision of public institutions during the 19th century. This pattern is consistent with the substitutability of formal and informal institutions as means to solve collective action problems, and with the association between “communal” values and conservative policies. These findings also suggest that, while under studied, social learning is an important determinant of individualism.
