Report Title

Modeling and Measuring the Effects of Economic Shocks on a Defense Industrial Base

Key Themes and Objectives

1. Context: Economic shocks (unanticipated changes in resource allocation conditions) pose significant risks to defense capabilities by degrading military readiness, diverting resources, and increasing costs, similar to kinetic supply interdiction efforts.
2. Core Question: How can data-informed analysis better support defense decision-makers in managing the risks of economic shocks?
3. Methodology: Reviewed existing empirical methods from economics (VAR, Input-Output, CGE models, Panel Regression) and identified gaps in their application to defense scenarios.
4. Research Approach:
   • Analyzed historical and hypothetical vignettes (e.g., WWII rubber supply, Iranian sanctions) to define analytic capability requirements.
   • Assessed current methodologies for addressing these requirements and identified limitations (e.g., data dependence, context specificity).
   • Proposed frameworks to connect empirical analysis with decision-making, incorporating modular structures tailored to shock latency and production process characteristics.

Key Findings

1. Vignettes as Shaping Exercises: Case studies (e.g., U.S. Civil War, Iranian sanctions) highlight that economic shocks can cause meaningful damage to defense postures by restricting supply, diverting resources, and imposing costs.
2. Workhorse Methods Applicability:
   • VAR models excel at forecasting dynamic effects over time.
   • Input-Output (I-O) models quantify short-term ripple effects through supply chains.
   • Computable General Equilibrium (CGE) models simulate long-term behavioral adaptations.
   • Panel Regression models provide precise causal estimates under specific conditions.
3. Gaps and Limitations:
   • No single method fully addresses all analytic needs; context dependence and adaptation introduce uncertainty.
   • Frameworks are needed to bridge technical methods with defense decision-making, accounting for shock latency and resilience mechanisms.
4. Recommendations:
   • Invest in a multidisciplinary program advancing data-informed shock management (E.g., integrating economics, political science, sociology).
   • Prioritize modular frameworks to connect empirical insights to courses of action (COAs), starting with achievable "low-hanging fruit" to build foundational knowledge.

Conclusions

Economic shocks represent a critical risk to defense capabilities, requiring proactive analytic support to enhance resilience. While existing methods offer value, further research and new frameworks are essential to translate data insights into actionable defense strategies.
