INTERTEMPORAL SUBSTITUTION IN CONSUMPTION: A LITERATURE REVIEW
综述了消费跨期替代弹性(EIS)的实证研究现状,讨论理论进展和估计挑战,指出偏离标准模型可得出更高EIS值,为宏观和金融模型校准提供参数选择参考。
Abstract This paper reviews the status quo of the empirical literature about the elasticity of intertemporal substitution (EIS) in consumption. Aiming to answer the question what the true magnitude of the parameter really is, it discusses several recent advances of the theory and highlights challenges for the estimation. Although the general discussion still seems to be prevailed by Hall's early EIS estimates close to zero, we show that several deviations from the time‐additive constant relative risk aversion model speak in favor of considerably higher values. Our treatment is supposed to provide researchers a hint at which parameter is a reasonable and incontrovertible choice for the calibration of models in macroeconomics and finance.
