Random-Time Aggregation in Partial Adjustment Models
部分调整模型中的随机时间聚合
How is econometric analysis (of partial adjustment models) affected by the fact that, although data collection is done at regular, fixed intervals of time, economic decisions are made at random intervals of time? This article addresses this question by modeling the economic decision-making process as a general point process. Under random-time aggregation, (1) inference on the speed of adjustment is biased-adjustments are a function of the intensity of the point process and…
