证明了当边际效用正则变化时，最优储蓄问题中的消费函数是渐近线性的。我们还分析地刻画了财富的渐近边际消费倾向。我们的结果有助于在数值计算消耗函数时获得良好的初始猜测，并为在网格外线性外推消耗函数提供了理论依据。

英文摘要：
We prove that the consumption functions in optimal savings problems are asymptotically linear if the marginal utility is regularly varying. We also analytically characterize the asymptotic marginal propensities to consume (MPCs) out of wealth. Our results are useful for obtaining good initial guesses when numerically computing consumption functions, and provide a theoretical justification for linearly extrapolating consumption functions outside the grid.
