“…Nincic and Cusack (1979) examined the impact that election cycles have on spending, and found that upcoming elections are correlated with increased defence spending. Griffin, Wallace, and Devine (1982) showed that regressions which include internal factors, such as the size of the government, GDP, inflation, and unemployment, outperform regressions which focus solely on external factors. Cusack and Ward (1981) also finds that internal factors, such as elections, aggregate demand fluctuations, and general economic performance, outperform external factors as determinants of defence budgets, in the US, USSR, and China.…”
