Princeton/Stanford Working Papers in Classics A model of real income growth in Roman Italy Version 2.0 February 2007 Walter Scheidel Stanford University Abstract: This paper presents a new model of the main exogenous and endogenous determinants of real income growth in Italy in the last two centuries BC. I argue that war-related demographic attrition, emigration and the urban graveyard effect converged in constraining the growth of the freeborn population despite increased access to material resources that would otherwise have been conducive to demographic growth and concomitant depression of real incomes; that massive redistribution of financial resources from Roman elites and provincial subjects to large elements of the Italian commoner population in the terminal phase of the Republican period raised average household wealth and improved average well-being; and that despite serious uncertainties about the demographic and occupational distribution of such benefits, the evidence is consistent with the notion of rising real incomes in sub-elite strata of the Italian population. I conclude my presentation with a dynamic model of growth and decline in real income in Roman Italy followed by a brief look at comparable historical scenarios in early modern Europe. I hope to make it probable that due to a historically specific configuration of circumstances created by the mechanisms of Roman Republican politics and imperialism, the Italian heartland of the emerging empire witnessed temporary but ultimately unsustainable improvements in income and consumption levels well beyond elite circles. © Walter Scheidel.
