European Nato Burden Sharing 1993-2022: New Perspectives

The R scripts are used to calculate defense burdens and different benefit-share measures, to conduct Spearman rank correlation tests, and to perform two-sided Wilcoxon signed-rank tests. The analyses compare defense burdens with individual and average benefit shares under different weighting schemes. Separate analyses are provided for all NATO members, European NATO members, and a specification in which France, Germany, and the United Kingdom are aggregated and treated as a single unit.

The replication package also contains code to reproduce the figures presented in the paper. The statistical test results are stored in R data frames, while the generated figures are written to the plots directory. The individual R scripts can be executed independently of one another.

The README additionally documents the data sources, software and package requirements, computational requirements, and the correspondence between tables, figures, scripts, and output files.
