Aid versus sanctions for taming oppressors: theory and case study of the Iraqi Kurds

We model an oppressor aiming at victimizing an excluded group in his country, with two main variants. A foreign power affects his behaviour using either conditional aid, subject to the dictator’s participation constraint, or the threat of sanctions, broadly defined, subject to the credibility constraint. The choice between the two is either determined by the latter, or by their relative cost. Aid is preferred when the threat of sanctions is ineffective, and sanctions are too expensive. Sanctions might be imposed, if the threat is ineffective. A case study of the Iraqi Kurds after Iraq was subject to sanctions is presented.     

ON THE RELATIONSHIP BETWEEN MILITARY EXPENDITURE,THREAT, AND ECONOMIC GROWTH: A NONLINEAR APPROACH

The main objective of the paper is to decipher the military expenditure–economic growth relationship, taking the level of economic development (income) into consideration. Our findings suggest the following: (i) military expenditure has a significantly negative relationship to economic growth for the 23 countries with initial incomes (threshold variable) less than or equal to $475.93; (ii) when the threat level is heightened, economic growth (23 countries) is expected to decrease. However, military expenditure in the presence of sufficiently large threats increases growth; (iii) for the remaining 69 countries whose initial incomes (real GDP per capita in 1992 price) exceed $475.93, no significant relationship exists whether the threat variable is taken into consideration or not.     

Globalisation in the defence industry: An exploration of the paradigm for us and European defence firms and the implications for being global players

This paper explores some of the key issues associated with the restructuring of the defence industry. A comparison is made between the US and the European Defence Industrial Bases in terms of the drivers for change and the paradigms within which change has taken place. Having shown that some very important differences exist, the paper then explores the approaches that have been adopted for industry consolidation and references them to the academic literature on mergers and acquisitions (M&As) and strategic alliances (SAs). Given that most of the key defence players recognise the need to be global players, the paper presents an argument that the European firms’ experience of operating with a wide range of forms of corporate alliance will serve them in good stead for operating on a global defence scale. US firms, in contrast, have focused largely on M&A activity.     

Nuclear weapons,the United States and alliances in Europe and Asia: Toward an institutional perspective

America’s alliances in Europe and East Asia all involve some institutional cooperation on U.S. nuclear weapons policy, planning or employment—from consultative fora in Asia to joint policy and sharing of nuclear warheads in NATO. Such cooperation is often analyzed through the prism of “extended nuclear deterrence,” which focuses on the extension of U.S. security guarantees and their effect on potential adversaries. This article argues that this underplays the importance of institutional factors: Allies have historically addressed a range of objectives through such cooperation, which has helped to catalyze agreements about broader alliance strategy. The varied form such cooperation takes in different alliances also flows from the respective bargaining power of allies and the relative importance of consensus, rather than perceived threats. The article concludes that nuclear weapons cooperation will remain crucial in successful U.S. alliance management, as allies negotiate their relationship with each other in the face of geostrategic change.     

Compromise allocation in multivariate stratified sampling: An integer solution

The problem of determining the sample sizes in various strata when several characteristics are under study is formulated as a nonlinear multistage decision problem. Dynamic programming is used to obtain an integer solution to the problem. © 1997 John Wiley & Sons, Inc.     

Optimizing submarine berthing with a persistence incentive

Submarine berthing plans reserve mooring locations for inbound U.S. Navy nuclear submarines prior to their port entrance. Once in port, submarines may be shifted to different berthing locations to allow them to better receive services they require or to make way for other shifted vessels. However, submarine berth shifting is expensive, labor intensive, and potentially hazardous. This article presents an optimization model for submarine berth planning and demonstrates it with Naval Submarine Base, San Diego. After a berthing plan has been approved and published, changed requests for services, delays, and early arrival of inbound submarines are routine events, requiring frequent revisions. To encourage trust in the planning process, the effect on the solution of revisions in the input is kept small by incorporating a persistence incentive in the optimization model. © 1997 John Wiley & Sons, Inc.

Distribution of the workload in multiclass queueing systems with server vacations

The steady-state workload at an arbitrary time is considered for several single-server queueing systems with nonpreemptive services for multiple classes of customers (arriving according to Poisson processes) and server vacation (switchover) times. The distribution of the workload at an arbitrary point during the vacation period is obtained for systems with setup times, and for polling systems with exhaustive, gated, or globally gated service disciplines. From the stochastic decomposition property, this workload is added to the workload in the corresponding M/G/1 system without vacations to give the workload at an arbitrary time in vacation systems. Dependence of the workload distribution on the vacation parameters is studied.
