[영문]The demographic effects of the epidemics of plague in Early Modern Europe and their economic consequences illuminate the evolution of property structures and of wealth distribution during and after a mortality crisis. An analysis of the high-quality data available for the Italian city of Ivrea at the time of the 1630 plague shows the exceptional resilience of property structures. Like the social structures of the period, property structures were able to recover quickly, informed as they were by the lessons learnt by trial and error by the patrician families of the late Middle Ages, whose patrimonies had been badly damaged by the Black Death. In a period of recurrent catastrophes that struck European populations during the Old Demographic Regime, apparently 'inegalitarian' institutions seem to have had long-term 'egalitarian' effects.
