Household sorting in an ancient setting
利用希腊岛屿三个历史时期古代定居点的考古数据构建消费指标，发现高质量消费品更集中于定居点中心，而低质量消费品分布较分散，这种梯度可能反映家庭消费篮子的差异。
We use archaeological data from ancient settlements of three different historical eras on a Greek island to construct novel measures of consumption. Using these, we show that the shares of high-quality consumption goods were relatively more concentrated closer to the center of nucleated settlements as compared to low-quality consumption goods. There is no such pattern in a placebo settlement. In this unique setting, these quality gradients may reflect differences in household consumption baskets across these settlements. We argue that some alternative, trade or production based hypotheses for such gradients can be weakly ruled out based on our data and archaeological sources.
