This study models the structural sources of variation in the use of selective (discriminate) repression within 89 civil wars fought between 1981 and 2005. The severity of repressive violence is modeled as a function of the amount of territory being contested by the insurgents. This idea is operationalized using measures of the location, size, and density of insurgency violence. The analysis finds evidence that the repressive behavior of both governments and rebel groups is linked to conflict geography. Governments violate physical integrity rights more frequently and kill more civilians the greater the overall amount of territory under contestation. Rebels kill more civilians in highly dispersed insurgencies that lack a clear epicenter. 相似文献

We explore the impact of strategic assessment efforts on military organizations at war. To do so, we construct a model to explore the impact of a principal’s choice among imperfect performance metrics for a military operation. In doing so, the principal must consider both the incentivizing and informational properties of the metric. We show the conditions under which uncertainty regarding the nature of the agent, as well as uncertainty regarding the operational environment, drives a metric choice that induces pathological behavior from the agent. More specifically, a poor metric choice can create an overly optimistic assessment and end up prolonging the conflict. We illustrate the model’s insights in the cases of World War II and the Vietnam War. 相似文献

A nonlinear optimization model is developed in this paper to identify the optimal replacement strategy for military aircraft. In the model, the aircraft operating and maintenance (O&M) costs per available year are estimated as a function of age during the aircraft life cycle. After determining the optimal replacement policy, the model is applied to the CF Long-Range Patrol CP-140A Arcturus fleet. A sensitivity analysis is also carried out to assess the impact of some key model parameters on the result. 相似文献

This study uses the Feder-Ram model in conjunction with the military Keynesian model to examine the nexus between defence spending and economic growth in Sri Lanka. We find that the Keynesian aggregate demand model is better suited to analyse the link than the Feder-Ram model for the case of Sri Lanka. Based upon our results we expect a higher economic growth rate in Sri Lanka if more public resources are diverted from the defence to civilian sectors of the economy, now that the war between the government and separatist guerrillas has come to an end. However, recent post war events cast doubt upon whether a diversion of sources from military to non-military spending will actually occur. We conclude that the sanguine predictions of our economic analysis are entirely dependent upon the political decisions of the Sri Lankan government for their realization. 相似文献

Despite the large number and variety of studies addressing the relationship between military spending and economic growth, a consensus regarding the exact nature of any relationship between the two has proven elusive. This study uses a panel co-integration approach to examine the relationship between military spending and economic growth in the five South Asian countries of India, Pakistan, Nepal, Sri Lanka and Bangladesh over the period of 1988–2007. It finds that a 1% increase in military spending increases real GDP by only 0.04%, suggesting that the substantial amount of public expenditure that is currently directed towards military purposes in these countries has a negligible impact upon economic growth. 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

This comment addresses the Rohlfs–Sullivan analysis titled: ‘The Cost-Effectiveness of Armored Tactical Wheeled Vehicles [TWVs] for Overseas US Army Operations.’ The analysis evaluated policies to replace Type 1 and 2 TWVs with Type 3s. There is no evidence the analysis factored in fatality causes, fatality relationships to vehicles, or compared survivability of vehicles. Furthermore, it did not note when Type 3 TWVs were requested, when they impacted fatalities, or TWV use policies. It also assumed Type 3 TWVs prompted negative unit behaviors while discounting evidence of positive behaviors. In summary, the analysis is incomplete and should be revised. 相似文献

One of the most important issues facing the post‐Cold War U.S. defense establishment concerns the future allocation of combat tasks and responsibilities among different branches of the armed forces. The challenge is to reduce unnecessary redundancy across roles and missions when resources are highly constrained, without compromising military effectiveness. Defining the policy problem as one of resource allocation rather than operational effectiveness, we develop a methodology for allocating roles and missions. Our methodology focuses at the highest level of force aggregation and uses a mathematical programming model to produce cross‐service cross‐mission trade‐offs that will yield the best total force combat and non‐combat potential within resource consumption constraints. 相似文献

South Africa and Kenya experienced various forms of conflict and gross human rights abuse between 1948–1994 and 1963–2002 respectively. In both situations, the conflicts were motivated by various factors; these included unequal distribution of socio-economic resources and skewed political relationships. The centrality of human rights abuse and political violence to both situations places similar issues on the agenda for analysis. In both cases opposition to regimes was justified on the basis that the political systems were constructed in such a way that limited alternative conceptions and prevented democratic freedom (until 19921 in Kenya and 1994 in South Africa). After undergoing transition to democratic rule in 1994, South Africa engaged the idea of a truth and reconciliation commission as an instrument for dealing with its past conflicts. The South African case animated widespread international interest and after an electoral victory in 2002, the National Rainbow Coalition (NARC) government in Kenya mooted the same idea. By the end of 2004 however the NARC government seems to have lost interest in the truth commission concept; this paper probes the question why? Broadly there is room for alternative interpretations both within and between the two cases on how conflicts were perpetuated and the potency of a truth and reconciliation commission as a viable alternative for dealing with past conflicts. This paper broadly aims to offer a clearer account of conflicts and mechanisms for dealing with them from the conceptual lenses of conflict management theory. 相似文献
