This paper presents an alternative approach for analyzing international competition and alliances as rent‐seeking contests that are able to capture the impure public good nature of defense spending. Two‐country Cournot and Stackelberg games are considered and comparative static results derived. A three‐country model is investigated, and alliance behavior is explored in the context of this rent‐seeking model. The conjecture that an alliance may become less effective if the allies’ interests become more closely aligned is verified. Finally, the model is generalized, and a Nash‐Cournot equilibrium is computed. 相似文献

ON THE CHOICE OF MULTI-TASK R&D DEFENSE PROJECTS: A CASE STUDY OF The ISRAELI MISSILE DEFENSE SYSTEM
Investments in R&D constitute a major share of the expenditures of the hi-tech industry since, generally, they enable firms to successfully compete in the rapidly and constantly changing markets for hi-tech products and services. The role of R&D projects is particularly important in the areas of defense and homeland security due to the nature of warfare and the continuous threats posed by arms races and by terror organizations. This study analyzes the choice of the R&D projects designed to counter multiple related military threats. It develops the methodology required to assess whether it is preferable to develop one project to thwart several related threats, or several distinct projects, each of which provides an answer to one specific threat or a partial set of the threats. An analytic solution is provided and assessed for two simple models with two related threats. A solution of the model is then provided for any number of related threats, using a dynamic programming methodology. Finally, we demonstrate the usefulness of our model and methodology to Israel’s missile defense problem; that is, we show how to optimally develop systems aimed at thwarting the multiple threats of short-, medium-, and long-range missiles. 相似文献

AbstractThis paper examines the impact of civil war on military expenditure. We employ two measures of military expenditure: the share of military expenditure in general government expenditure and the logarithm of military expenditures. We would reasonably expect a priori that military expenditure as a share of general government expenditure increases during a civil war and that such increases would taper off over the duration of a civil war. We also explore whether the termination of a civil war induces a decline in the share of military expenditure as a share of the general government expenditure in the short-run. We find evidence the of share of military expenditure increases during a civil war and falls in the year succeeding the end of a civil war, and, in particular, if a war ends in a peace treaty. The level of military expenditures, however, rises during civil wars and does not appear to decline in the short-term after the end of a civil war. 相似文献

The Obama administration has made a great effort to increase the role of advanced conventional weaponry in US national security thinking and practice, in part to help reinvigorate the global nuclear disarmament agenda by reducing the role played by nuclear weapons in the US defense posture. However, such a strategy is fundamentally flawed because increases in US conventional superiority will exacerbate US relative strength vis-à-vis other powers, and therefore make the prospect of a nuclear weapon-free world seem less attractive to Washington's current and potential nuclear rivals. Consequently, it is highly likely that the impact of efforts to increase US advanced conventional superiority through ballistic missile defense and a conventional “prompt global strike” program will ensure that the Obama administration is adopting a pathway to nuclear abolition on which it is the sole traveler for the foreseeable future. 相似文献

In marked contrast with previous decades, defense issues in Argentina have started to receive increasing political attention over the last few years. The main goal of this article is to account for this new found interest in defense policy. The article contends that this revival could be accounted for by both the implementation of a neo-developmentalist strategy and a type of control that emphasizes civilian oversight over the armed forces. Both factors have promoted the implementation of policies that favored an increase in the military budget, the reconstruction of the defense industry and the establishment of a new military doctrine. This article evaluates the impact of factors that have not been previously considered by the literature on defense attention in South America. 相似文献

This critical comment examines the incentives, major priorities, difficulties and first results of the Russian military reform that is being implemented since 2008. The authors conclude that despite numerous drawbacks and barriers to the reformist efforts certain successes can be identified. Particularly, there is a clear shift from the old-fashioned, Soviet-type army to a more compact, mobile, better equipped and combat-ready armed forces that are capable to cope with today's challenges to Russian national security. 相似文献
