HISTROOTS plans to study the effect of history on conflict and economic development with an historical microscope. Following the lead of the new institutional economics, part of the literature argues that institutions cause differences in productivity and factor endowments which, in turn, explain economic development. An alternative view assumes that human capital shapes institutional changes and, therefore, institutions are endogenous. This project tries to move one step further in this debate by taking an approach that uses administrative data on the first colonizers of Latin America. The data contains some personal characteristics on each of the settlers from 1492 to 1540 (town of origin in Spain, occupation, education, city of arrival in the Americas, etc). Using within-country analysis, since we have information on the precise destinations of the first “pobladores” (settlers), and the different institutional set-ups during the first years of colonization for different geographical areas in Latin America, HISTROOTS will reexamine the issue of institutions versus human capital in the explanation of economic development and conflict. The institutions in the initial times of colonization were not the same in all the regions of Latin America and, in many cases, represented an evolution of pre-Colombian institutions. The new data allows also the analysis of the interaction between human capital and institutions in the initial times.
