Chapter 7: Limitations and future research
Chapter Text
Limitations
This study has several limitations. First, its reliance on the cross- sectional design of the 2022 SCF prohibits the establishment of causal relationships. While our analysis identifies strong associations between financial hardship, government assistance, and precautionary savings, we cannot definitively conclude that these factors caused the observed saving behavior.
Longitudinal data would be necessary to track changes in household savings over time in direct response to specific events. Second, our measures for key HBM constructs are based on survey responses and may be subject to recall bias. For instance, self-reported financial hardship captures a household's subjective experience but may not perfectly align with objective financial metrics. Finally, while the SCF is a high-quality, nationally representative dataset, the findings are specific to the U.S. context and may not be generalizable to countries with different healthcare systems, social safety nets, and cultural norms around saving.
Future research
Several key areas warrant further investigation. First, longitudinal studies could assess the long-term efficacy of integrated health-financial products, particularly their return on investment across diverse demographic segments. Second, research should explore how digital tools (e.g., fintech platforms) might scale financial services during crises, especially in resource - constrained settings where traditional banking infrastructure is limited. Third, future studies should explore additional sociocultural factors that may influence saving behaviors, such as religious affiliation, formative financial experiences during upbringing, and geographic location (e.g., urban versus rural settings), to provide a more nuanced understanding of financial decision-making. Finally, comparative analyses of public-private partnerships could identify best practices for fostering financial resilience, bridging gaps between policy design and market realities. Such work would inform both business strategies and policymaking in an era of compounding health and economic uncertainties.
