Patience and Comparative Development* Thomas Dohmen Benjamin Enke Armin Falk David Huffman Uwe Sunde May 29, 2018 Abstract This paper studies the role of heterogeneity in patience for comparative devel- opment. The empirical analysis is based on a simple OLG model in which patience drives the accumulation of physical capital, human capital, productivity improve- ments, and hence income. Based on a globally representative dataset on patience in 76 countries, we study the implications of the model through a combination of reduced-form estimations and simulations. In the data, patience is strongly corre- lated with income levels, income growth, and the accumulation of physical capital, human capital, and productivity. These relationships hold across countries, sub- national regions, and individuals. In the reduced-form analyses, the quantitative magnitude of the relationship between patience and income strongly increases in the level of aggregation. A simple parameterized version of the model generates comparable aggregation effects as a result of production complementarities and equilibrium effects, and illustrates that variation in preference endowments can account for a considerable part of the observed variation in per capita income.
