Summary
This study differentiates between one-decision and sequential-decision fertility models. Unanticipated events are key to sequential models, and empirical tests suggest sequential models better explain fertility decisions.
Area of Science:
- Demography
- Sociology
- Behavioral Economics
Background:
- Fertility decisions are complex, influenced by various individual and societal factors.
- Existing models often simplify decision-making processes, potentially overlooking dynamic influences.
- Distinguishing between static and dynamic models is crucial for accurate fertility analysis.
Purpose of the Study:
- To establish clear criteria for differentiating between one-decision and sequential-decision models of fertility.
- To empirically test which model framework better explains fertility behavior and plans.
- To highlight the role of unforeseen events in shaping fertility trajectories.
Main Methods:
- Defined criteria for one-decision versus sequential-decision fertility models.
- Proposed that sequential models require evidence of unanticipated intervening events not caused by fertility itself.
- Developed and applied two empirical tests: one predicting fertility plans and another predicting fertility events.
Main Results:
- Sequential-decision models require demonstrating the impact of unanticipated intervening events.
- Empirical tests provided support for sequential models over one-decision models.
- The influence of unexpected life events on fertility choices was empirically supported.
Conclusions:
- Sequential-decision models offer a more nuanced understanding of fertility dynamics.
- Unforeseen life events significantly impact fertility planning and outcomes.
- Future research should focus on incorporating dynamic, event-driven factors into fertility models.
