This paper provides new evidence on the question of the effects of defense spending on aggregate output in the United States. Earlier studies of this basic issue relied on traditional econometric techniques and the neoclassical production function theory. In this paper, recently developed cointegration methodology and modeling that is inspired by new macroeconomic theory is employed. The results from earlier studies concerning the effects of defense spending are mixed. The findings presented in this paper reveal that there is a quantitatively important and positive relation between defense spending and aggregate output in the United States. 相似文献

There are conflicting views as to the relationship between a nation’s defense expenditure (DE) and its population’s income inequality (INEQ). DE, always an important part of government budget, can easily crowd out transfer payments, necessary to improve INEQ; however, these payments may also create a demand that may raise the income levels of the lower income earners. Consequently, the relationship between DE and INEQ is an important question. This paper examines the relationship between DE and INEQ in China for the period of 1989–2012. Utilizing basic cointegration and causality tests, our objective is to add to the literature by providing evidence that China’s DE, in fact, do have an impact on INEQ. 相似文献

Traditionally, policy and planning have been institutionally weak in the Naval Staff (Office of the Chief of Naval Operations – OPNAV). In their place, the N8 (Programming) has dominated resource decision-making, and, by default, decisions relating to policy and planning. Recent uncertainty over defense authorization and appropriations has resulted in calls for a greater role to be played by the N3/5, Policy and Plans Directorate. The article argues that reform of the Department of the Navy’s planning process is urgently needed. OPNAV’s weak planning and overly dominant programming practices are compared with those of the Departments of the Army and Air Force and are shown to be out of conformance with them. The article concludes with specific and detailed recommendations for reform of both the current planning and programming processes. 相似文献

Does a great power need to formulate a long-term Grand Strategy to guide its foreign policy actions? While some scholars continue to debate the competing merits of various grand strategies, a growing literature now emphasizes emergent learning and improvisation as the keys to success, as opposed to implementing a long-term design. In this article, I explore these scholarly arguments by framing the debate as one between two schools of thought, Grand Strategy and Emergent Strategy. After presenting the main arguments and the historical examples associated with each school, I evaluate the two approaches across four categories: the type of international security environment each of them is most suited for, the way each approach deals with short-term vs. long-term priorities, the domestic political conditions needed for each approach to be successful, and the type of presidential management qualities each school demands. Lastly, I discuss the implications of these arguments for the scholarship and the practice of foreign policy and national security strategy. 相似文献

Countries with a federalist system of government have different arrangements for providing national security. US national security is provided by national and State defense forces. The quintessential national function – national defense – experienced some changes that enhanced the role of the States. Policy changes in the National Defense Authorization Act of 2008 (2008 NDAA) introduced new roles for the Governors and the State defense forces, or the National Guard. This article explores how the interests of Congress and States aligned in the 2008 NDAA such that the national defense function changed. This article finds that the national government continues to have the central coordinating role, but that the politics and provisions of the 2008 NDAA changed the national–State relationship in mission, decision-making, and command and control so that US federalism in the national defense function is evolving in unexpected ways. 相似文献

高超声速武器具有飞行速度快、精确毁伤和高效突防等特点,具有重要的战略威慑和实战应用价值,它能够大幅改变未来战争的态势,已成为大国打破战略平衡、打赢未来战争的新型“杀手锏”。随着高超声速武器逐步走向战场,世界各主要国家的反导防御体系将向更高预警维度、更快反应速度和更大打击力度的天地一体联合防御方向发展。本文分析了高超声速武器作战优势及其对未来战争的影响和威胁,阐述了美军现有反导预警能力的基本架构与能力缺陷,对其未来反高超声速武器的预警能力建设及发展态势进行了研判与预测。美军“优先发展天基反导作战体系,发挥低轨卫星主体作用”的反高超声速武器发展思路对于军队反导反高超声速武器能力建设具有一定的启示和借鉴作用。 相似文献
