D Of these two branches, the study of how historical events in a given place shape ow n economicoutcomesisthebetterdeveloped.Inlargepart,thisisbecauseitisrelatively lo a easy to map the locations of historical events to modern-day territories. If we know de d that something happened in one place and not another—for example, on one side of fro m a border but not the other—we can compare contemporary outcomes of these two h places, and thus learn about the role of whatever it was that differed. This strategy ttp s has been particularly fruitful in examining the role of institutions, which have the ://a c helpful property of tending to stay put in physical locations.1 A slight variation on a d e thisliteratureonpersistenceinplacesallowsformovementsoflargegroupsofpeople m ic from one place to another, recognizing that when these large-scale migrations take .o u place, people maybring withthem muchofwhateveritis—culture, institutions, and p.c o soforth—thatwasfoundintheirplaceoforigin.2 m Among the various place-based determinants of comparative development, the /jee a transition to agriculture is often cited as being of paramount importance in fostering /a d v thedevelopmentofmodernurbancivilizations.Thisideaisattheheartofavenerable a n c line of research among anthropologists and historians embracing social evolutionary e -a schema.EconomistsHibbsandOlsson(2004),Putterman(2008),andBorcan,Olsson, rtic and Putterman (2018) establish empirically a positive influence of early agricultural le-a b transitiononstateformationandcontemporaryincomesacrosscountries.Thisplace- s tra centered perspective on history points naturally toward thinking about aggregate or c t/d averageincomesinaparticularcountryorregioninthemodernworld. o i/1 The other approach to quantifying the role of history looks at heterogeneity in 0 .1 outcomeswithinapopulation.Thefocushereisonthelineageofanindividualandhow 0 9 3 this contributes to his or her relative economic standing and cultural attributes today /je e (Fenske2013;Alesina,Giuliano,andNunn2013).Overperiodsofafewgenerations, a /jv the effects of one’s lineage on current outcomes are addressed under the heading of y 0 2 intergenerational mobility. However, economists are increasingly realizing that there 9 /5 areelementsoflineagethatareimportantbeyondwhatcanbeunderstoodfrom,say, 10 7 aonegenerationaltransitionmatrix.Recentattemptstolengthentheintergenerational 54 7 horizon include work by Clark (2015) and Guell et al.

As Kra¨tli (2001) writes, “At the core of the public representation of a d e pastoralism is the idea that “pastoralism” and “modern life” are mutually exclusive, m ic as two successive stages of human development in a unique line that goes from .o u nature to civilization, passing from sedentary life and agriculture. This frame offers p.c o no ground on which pastoralism and [the] modern world could meet: one being m thought to begin where the other is supposed to end”. This view of herders as less /jee a civilized than agriculturalists, or as a dead end branch line off the main path from /a d v agriculturetocivilization,echoesmillennia-oldChinese,Persian,andEgyptianviews a n c ofsteppeanddesertnomads.Motivatedbythissweepingnarrative,ourpaperexplores e -a whether a similar evolutionary approach can also be traced in the current economic rtic outcomesofdescendantsofgroupsthatpracticeddifferentsubsistencepatternsduring le-a b the preindustrial era.

Hence, culture is a natural suspect, as de d it is something that can vary among individuals in a given location based on their fro m lineage.
