Bedeviled by a Paradox: Nitze,Bundy, and an Incipient Nuclear Norm

ABSTRACT

This article explores how two influential American policy makers—Paul Nitze and McGeorge Bundy—wrestled with the idea of a norm against the use of nuclear weapons. Existing scholarship has overlooked how both Bundy and Nitze came to understand the idea of nuclear non-use, especially related to the credibility of threats to use nuclear weapons. Using documentary evidence from their personal papers, this article illuminates the thinking of Bundy and Nitze, finding that both engaged with the idea of a norm of non-use of nuclear weapons in their strategic writing and thought.     

Military spending and economic growth in South Africa

This paper undertakes an empirical analysis of the economic effects of military spending on the South African economy. It estimates a neo‐classical model common in the literature at the level of the macroeconomy and at the level of the manufacturing sector. An attempt is made to improve upon the model by allowing the data to determine the dynamic structure of the model through an ARDL procedure. No significant impact of military spending is found in aggregate, but there is a significant negative impact for the manufacturing sector. This suggests that the cuts in domestic military procurement that have occurred since 1989 could lead to improved economic performance in South Africa through their impact on the manufacturing sector.     

MILITARY SPENDING AND ECONOMIC GROWTH IN SOUTH ASIA: COMMENT AND RECONSIDERATION

In a recent paper in this journal, Wijewerra and Webb study the connection between military spending and gross domestic product (GDP) in a group of five South Asian countries, finding a small but statistically significant positive relationship between military spending and GDP. This paper reviews their approach and proposes an alternative which tries to deal with the problems of omitted variables and variable construction. It finds, in contrast, that a higher share of military spending in GDP is associated with lower growth of GDP per capita.     

THE ROLLBACK OF LIBYA'S CHEMICAL WEAPONS PROGRAM

In 2003, Libyan leader Muammar Qaddafi agreed to eliminate his country's weapons of mass destruction (WMD) programs and long-range Scud missiles under strict verification by U.S. and British experts and international inspectors. This article examines the negotiation and implementation of Libya's WMD rollback, with a primary focus on its chemical weapons program, and draws some lessons for the future. Although the Libyan case was unique in many ways, some aspects have relevance for other countries, including the critical role played by multilateral nonproliferation organizations, the utility of economic sanctions and export controls, the importance of a flexible U.S. disarmament funding mechanism, the value of rotating technical assistance teams in and out of the country that is disarming, and the desirability of remaining politically engaged with a former proliferator after rollback is complete.     

Interval scheduling: A survey

In interval scheduling, not only the processing times of the jobs but also their starting times are given. This article surveys the area of interval scheduling and presents proofs of results that have been known within the community for some time. We first review the complexity and approximability of different variants of interval scheduling problems. Next, we motivate the relevance of interval scheduling problems by providing an overview of applications that have appeared in literature. Finally, we focus on algorithmic results for two important variants of interval scheduling problems. In one variant we deal with nonidentical machines: instead of each machine being continuously available, there is a given interval for each machine in which it is available. In another variant, the machines are continuously available but they are ordered, and each job has a given “maximal” machine on which it can be processed. We investigate the complexity of these problems and describe algorithms for their solution. © 2007 Wiley Periodicals, Inc. Naval Research Logistics, 2007     

Technical note – operational statistics: Properties and the risk‐averse case

Consider a repeated newsvendor problem for managing the inventory of perishable products. When the parameter of the demand distribution is unknown, it has been shown that the traditional separated estimation and optimization (SEO) approach could lead to suboptimality. To address this issue, an integrated approach called operational statistics (OS) was developed by Chu et al., Oper Res Lett 36 (2008) 110–116. In this note, we first study the properties of this approach and compare its performance with that of the traditional SEO approach. It is shown that OS is consistent and superior to SEO. The benefit of using OS is larger when the demand variability is higher. We then generalize OS to the risk‐averse case under the conditional value‐at‐risk (CVaR) criterion. To model risk from both demand sampling and future demand uncertainty, we introduce a new criterion, called the total CVaR, and find the optimal OS under this new criterion. © 2015 Wiley Periodicals, Inc.
