Defense burden data, 1995 cross-section

Source: R/data.R
defense_burden.Rd

A 179-country cross-section of defense spending and conflict indicators for 1995, drawn from the replication archive of Wimpy, Whitten, and Williams (2021). Three row-standardized spatial weights matrices connect the units through different channels: contiguity, alliance, and defense pact.

Usage

defense_burden

Format

A named list with four elements:

data

A tibble with 179 rows and 12 variables, arranged by Correlates of War country code (ccode). Variables:

  • ccode - Correlates of War country code.

  • year - Calendar year (1995).

  • ch_milex - Change in military expenditures (outcome).

  • milex_tm1 - Lagged military expenditures.

  • log_pop_tm1 - Lagged log population.

  • civilwar_tm1 - Lagged civil war indicator.

  • total_wars_tm1 - Lagged count of interstate wars.

  • alliance_us - Alliance with the United States.

  • ch_milex_us - Change in U.S. military expenditures.

  • ch_milex_ussr - Change in Soviet/Russian military expenditures.

  • region - Integer region code (1-5).

  • region_name - Factor: Europe, N Africa/Middle East, Africa, Asia/Oceania, Americas.

W_contig

A 179 x 179 row-standardized sparse dgCMatrix encoding geographic contiguity.

W_alliance

A 179 x 179 row-standardized sparse dgCMatrix encoding alliance ties.

W_defense

A 179 x 179 row-standardized sparse dgCMatrix encoding mutual defense pacts.

Details

This cross-section is intended for pedagogical demonstration of variable-specific SLX specifications. The original paper estimates a pooled panel SLX across 1950-2008 with year-specific weights matrices; that full-panel replication requires block-diagonal W support, which is planned for slxr v0.2.
