Do the rich save more? Evidence from linked survey and administrative data
利用英国住户的财富调查数据和收入行政数据，研究发现终生收入越高的人，私人财富积累率也越高；即使计入国家养老金，收入最高五分之一群体的财富收入比仍显著高于其他群体。
The nature of the relationship between lifetime income and saving rates is a longstanding empirical question and one that has been surprisingly difficult to answer. We use a new data set containing both individual survey data on wealth holdings and administrative data on earnings histories to examine this question. We find, for a sample of English households, evidence of a positive relationship between the rate of private wealth accumulation and levels of lifetime earnings. Even when state pension wealth is included, the top quintile of lifetime earnings have significantly higher wealth to lifetime earnings ratios than the other quintiles. Under this broad measure of wealth, those in the middle of the distribution of lifetime earnings accumulate the least wealth relative to their earnings.
