The importance of sampling frequency for estimates of well-being dynamics
利用高频面板调查，研究发现使用月度或季度数据时幸福感对冲击的持续性显著，而年度数据则显示持续性近乎为零，这对政策评估有重要启示。
Using a high-frequency panel survey, we examine the sensitivity of estimated self-reported well-being (SWB) dynamics to using monthly, quarterly, and yearly data. This is an important issue if SWB is to be used to evaluate policy. Results from autoregressive models that account for individual-level heterogeneity indicate that the estimated persistence using yearly data is near zero. However, estimated persistence from monthly and quarterly data is substantial. We estimate that persistence to shocks typically lasts around six months and has a net present value of 75–80 per cent of the contemporaneous effect. Estimates are similar for different domains of SWB.
