The effect of military expenditure on economic growth in developing countries has been investigated by many empirical literatures. However, there is little consensus of that effect and the diversity seems to come from the use of different models and different estimators. This article applies the Augmented Solow Growth Model to examine the influence of military expenditure on economic growth for 35 developing countries over the period of 1975–2009. By using the system Generalized Method of Moments (GMM) estimators, empirical results indicate that defence has a negative and significant effect on economic growth in the sample countries.  相似文献

This paper examines the impact of military spending on general government debt in the enlarged European Union (EU) countries. For this purpose, we use panel data analysis and provide estimates from a dynamic Generalized Method of Moments (GMM) panel model. The dynamics are found to be important and the results suggest that military expenditures do have a large positive impact on the share of general government debt in the EU.  相似文献

Abstract

This study applies the Sequential Panel Selection Method (SPSM), to investigate the convergence properties of the military expenditure of the North Atlantic Treaty Organization (NATO) during the period of 1990–2015. Compared to the traditional methods, SPSM considers fundamentally general spatial homogeneous and heterogeneous relationships with countries and examines the evolution of military expenditure. We find that four-fifths of NATO member countries have been convergent with the UK, but no country’s military expenditure is convergent with the US. This means that there is no significant linkage effect in the US for NATO military expenditure. While they are allies of the US, the majority of NATO member countries’ military expenditures are consistent with UK military expenditure. The main reasons are due to the geographical space layout and the international relationship convergence. The results indicate that more than four-fifths of NATO member countries have been coordinated with convergence theory and spillover effect.  相似文献

Thomas Schelling argues that armed adversaries face an inherent propensity toward peace or war embodied in their weaponry, geography and military organizations. Inherent propensity is the idea that there are characteristics embodied in the weapons that push adversaries toward peace or war, independent of the goals of the decision‐makers, the political disagreement between adversaries, and misperceptions about mutual resolve and hostility. We theoretically illustrate inherent propensity in conventional and nuclear arms settings using Lanchester and Intriligator war models. Our work extends the Intriligator‐Brito model, identifies when the competing Richardson and Intriligator‐Brito views of the relationship between arms races and war are correct, illustrates the stabilizing/destabilizing effects of alliances, and highlights the importance of arms quality control in the US‐USSR relationship.  相似文献

Cyprus, a small island state, gained independence from British colonial rule in 1960. For more that half its history as an independent state Cyprus has been under occupation following the 1974 Turkish invasion. Despite the fact that it has faced war, invasion and occupation, Cyprus has allocated a comparatively small proportion of its national income to defence. The average defence burden—military expenditure as a share of GDP—during 1964–98 was around 2.5%. However, as a result of a substantial shift in defence policy during the past decade or so, the defence burden during the 1990s has increased, averaging about 4% of GDP as Cyprus decided to implement an extensive military modernization program aiming to present a more credible military deterrence vis‐a‐vis Turkey. Empirical estimations of a demand function for Cypriot military expenditure suggest that it is positively affected by alliance spillins and external military threat.  相似文献

Within the EU France devotes to defence the largest financial and human resources although it is not the richest country, nor has it the largest population or labour force. The cost of nuclear weapons accounts for only a small fraction of this abnormally high French defence effort. If France had restructured its military capabilities at the same rate as its principal Allies during the 1985–1994 period, then French defence outlays would be about 20% less than at present. The fundamental reasons for France's excess defence outlay comprise virtual total dependence on French sources for equipment, produced in very small numbers; a military presence outside of Europe; and too many personnel. These deficiencies, and the consequent absence hitherto of a “peace dividend”, indicate a failure to identify the country's real strategic requirements, and a lack of will to reorganise efficiently French defence. The recently announced reform towards an all‐professional force is unlikely to achieve the potential and desirable improvement in cost‐effectiveness.  相似文献

This paper sets up a monetary endogenous growth model, and uses it to explain the ambiguous linkage between the military burden and the inflation rate observed in existing empirical studies. It is found that an expansion in the military burden has an ambiguous effect on the inflation rate depending upon the relative extent of two conflicting forces. More specifically, if the increase in the marginal benefit from holding money exceeds (falls short of) the increase in the marginal product of private capital, the inflation rate will rise (fall) in response. Moreover, it is found that an increase in the military burden will stimulate the balanced growth rate, confirming Benoit’s famous empirical findings.  相似文献
