The regional geography of social mobility in Mexico
研究了墨西哥各州的社会流动性，发现北部地区贫困家庭子女向上流动的机会高于中部和南部，存在明显的南北梯度。
We study intergenerational social mobility in Mexico at the subnational level to determine whether poorer regions have similar rates of social mobility as richer ones. We approximate socioeconomic status with an index that captures the variability across households in durable goods, services and education of household heads for both adult children and their parents. The estimated indicators suggest a clear north–south gradient in social mobility: the children of poor parents in the northern regions experience greater upward mobility than in the central and southern regions.
