UGURHAN G. BERKOK † 《Defence and Peace Economics》2013,24(3):191-204
The choice between balanced and specialized defence forces depends on the technology of defence output (e.g. whether a force scope multiplier is present), the existence of scope and scale economies, the platform customization costs and, of course, the level of defence budgets. Minimum force element levels (thresholds), and scale economies facilitate specialization as opposed to scope economies (e.g. platform‐sharing), scale diseconomies and the force scope multiplier (e.g. defence weakest‐link technology). When a balanced force is not optimal, the option value of a non‐optimally maintained force element must also include the opportunity cost arising from suboptimal force elements. Shrinking defence budgets may produce two surprising phenomena. If some force elements are shut down as a result of thresholds, the surviving ones may increase in platform numbers as well as enjoying closer‐to‐most‐desirable platforms. Furthermore, if heritage force elements are shut down within the budget contraction environment, overall defence capability might rise. 相似文献

Lisa Otto 《African Security Review》2013,22(2):88-95
The 17th Conference of the Parties (COP17) had been anticipated as the ‘African COP’, not only due to the African venue but also due to the opportunity it would afford African countries – with South Africa at the helm – to steer the debate on a global climate change regime. With the conference now over, lobby groups, international organisations, negotiators, observers and commentators alike have been taking stock of its outcome. Despite the litany of developmental and security implications of climate change, COP17 got underway with little hope that much might actually be achieved. In light of the discouraging condition of the global economy, with leading developed economies suffering financially, states were hardly in a mood to be making concessions that would impact their fiscal health. Nonetheless, an agreement was reached. Questions remain, however, about the significance of the outcome of the African COP for the world at large, but ultimately also for Africa. 相似文献
