Attitude,Aptitude, and Testing in the Efficient Mobilization of Military Manpower

Militaries commonly require recruits to pass a test that measures aptitude for military service. In this paper, we show that such tests may also act as a device for screening out low-motivation recruits, even if it is assumed that motivation is not measured by such tests and is not correlated with aptitude.     

Middle Powers And The Demand For Military Expenditures

This paper identifies and classifies middle power nations through the use of broad political science definitions, the demand for military expenditures models and gross domestic product (GDP) per capita. The latter is used as a simple quantifiable measure of relative and potential military power. The paper also develops and utilizes a threat variable that is applicable to middle power nations. The panel data analysis shows that the middle power nations react to threat variables that proxy global instability utilize foreign aid as a complementary policy tool along with military expenditures, and face significant trade-offs between military and non-military government spending.     

The Demand for Military Spending in Egypt

Egypt plays a pivotal role in the security of the Middle East as the doorway to Europe and its military expenditure reflects its involvement in the machinations of such an unstable region, showing considerable variation over the last 40?years. These characteristics make it a particularly interesting case study of the determinants of military spending. This paper specifies and estimates an econometric model of the Egyptian demand for military spending, taking into account important strategic and political factors. Both economic and strategic factors are found to play a role in determining military burden/spending, with clear positive effects of lagged military burden, suggesting some sort of institutional inertia, plus negative output and net exports effects. The strategic effect as a result of the impact of Israel’s military burden is mostly positive and significant, though its impact is reduced when the impact of important strategic events are taken into account. The military spending of Egypt’s allies Jordan and Syria generally seems to have had no effect on Egypt’s spending. These results are consistent over a range of econometric techniques.
