In this paper, the authors used the 10-wave Puget Sound Panel Dataset to investigate the response lag of a significant change in discretionary time use. In particular, we want to quantify the relative magnitude of the following factors: the built environment, family and social obligations, temporal constraints, or a psychological delay factor (people delay a behavioral change until the next life shock). To answer this question, the authors developed a survival model to treat 1) left censoring; 2) partial observation; and 3) multi-type exits. The results suggest that family and social obligations, as well as temporal constraints appear to play a more important role than the built environment. Support on the psychological delay factor is not evident. The authors also found that the probability of having a significant change in discretionary time use is negatively related to time progression, supporting the human adaptivity hypothesis.
