European Defense Spillover Indexes Measuring Security Integration, 2023

European Union member states' security and defense industrial policies are analyzed using two novel time series. The dataset includes the Defense Equipment Total Spillover Index and the Security TSI, created by Panagiotis Palaios and last updated in May 2026. It is used to model defense industrial spillovers and test relationships between defense spending and security integration.

Use Cases

• Modeling defense industrial spillovers across EU countries based on the Defense Equipment TSI and Security TSI.
• Analyzing relationships between defense spending and security integration based on geopolitical and economic factors.
• Testing theories of free-riding and policy cohesion within the European Union based on cross-border military dependencies.
• Investigating the political economy of defense alliances based on the expanded economic theory described.

Strengths

• Contains two novel, specifically named time series: the Defense Equipment Total Spillover Index and the Security TSI.
• Released under a permissive CC-BY-4.0 license, allowing for broad reuse.
• Last updated date is explicitly provided as 2026-05-11.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is very small at 35.0 KB, indicating limited scope.
