This paper models and estimates Greek defence spending over the 1950–1989 period. It employs the Stone‐Geary welfare function and estimates levels of defence expenditures by the Engle‐Granger two‐step procedure. The Dickey‐Fuller test regression for cointegration is specified in terms of the significance of additional augmentations. The Deaton‐Muellbauer functional form is then employed and an estimating equation for the expenditure share of defence is derived. This specification is compared with the levels equation through a number of non‐nested tests involving model transformation.  相似文献

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

In this paper, we analyse the dilemma confronted by a small country in relation to the consolidation taking place in the European defence industry. Assuming that Portugal must maintain its armed forces, and must retain a minor defence industry, this industry must be competitive in small niches. Competitiveness must be based on, amongst other elements, technical efficiency and technological change. We investigate this issue, first characterizing the threats faced by the Portuguese defence industry, then investigating its present efficiency and finally, we discuss its role in the consolidation of the European Industry. We conclude that the Portuguese defence industry has no alternative but to opt for innovation and European partnership, which are complementary policies, but which require the active involvement of the stakeholder (i.e. the Government) in effecting these fundamental shifts in direction and emphasis. If this strategy does not succeed, the defence policy should be based on offsets.  相似文献

By European Union and NATO standards, Greece consistently allocates substantial human and material resources to defence. The Greek defence burden (i.e. military expenditure as a share of GDP) has invariably been appreciably higher than the EU and NATO averages. The paper applies an autoregressive distributed lag model (ARDL) to present cointegrated estimates of the demand function for Greek military expenditure, in which domestic political factors and external security determinants are incorporated. Our empirical findings suggest that Greek defence spending over the period 1960-1998 has been influenced by both external security concerns, namely Turkey, as well as changes in the domestic political scene.  相似文献

It is intrinsic to the nature of military competition that the unit acquisition costs of defence systems rise generation by generation. Traditional “bottom‐up” methods of cost‐estimating cannot meet the increasing demands for extensive studies of many options before commencing design and, while “top‐down” estimating techniques are an improvement, in particular by reducing the time required for preparing estimates, they also are inadequate to meet current requirements. A new method has been devised, therefore, further developing “top‐down” methods using Bayesian techniques to make best use of the available information, whether certain or uncertain, and its accuracy established by example.  相似文献

This paper discusses the performance of Saudi Arabia's defence offset programmes. The Kingdom is involved in some of the World's biggest defence offset agreements and a review of the problems it has faced and the policies it has introduced provides a useful insight into that part of the international defence market where trade and development meet.

The paper reviews the origins and development of Saudi Arabia's major defence offset programmes. Saudi policies towards defence offsets are outlined before assessing the practical impact of the programmes themselves. The author concludes that Saudi Arabia's offset projects have had only a minor impact on the Kingdom's economy to date and makes a number of policy recommendations which are designed to enhance the utility of the programmes in the Kingdom's drive to enhance and diversify the technological base of its economy.  相似文献

Capability-based planning (CBP) is considered by many defence organisations to be the best practice for enterprise-level planning, analysis and management. This approach, loosely based around investment portfolio theory, is premised on balancing the cost, benefit and risk of capability options across the defence enterprise. However a number of authors have recently noted limitations of its current applications. The authors propose a more general, insurance-based approach, which can support the evolutionary improvement of the current CBP approach. This approach is implemented as hedging-based planning and aims to better reflect the enterprise nature of defence organisations, capturing both force structure and force generation aspects of military systems.  相似文献

European defence policy has been dominated by politics. This paper shows how economic principles can be used to derive guidelines for the formulation of European defence policy. The inefficiencies of the EU's existing defence arrangements are identified. It is shown that there is scope for efficiency improvements in the EU's Armed Forces and its defence industries.  相似文献

Assessing missile defence through the prism of offence–defence theory requires primarily an examination of legal and structural constraints on future development. New weapons technology is frequently cited as having the most critical impact on the offence–defence balance. Yet, the method for assessing the introduction of a new weapons technology tends to neglect projected maturity and instead focus excessively on the initial rudimentary capabilities. It is argued here that the North Atlantic Treaty Organisation’s (NATO’s) missile defence is set to incrementally become more advanced in terms of quality, quantity and mobility, which is supported by a strategy that is increasingly favouring offence. As the system gradually enhances the offensive advantage vis-à-vis Russia, NATO categorically rejects any legal or structural constraints on future deployments.  相似文献

The relationship between defence spending and economic growth has been examined extensively in recent years using the Feder (1983) model. These studies suffer from poor statistical results. In this paper, the earlier findings of Sezgin (1997), which used the Feder model are re‐estimated. Firstly, the stationarity of variables is tested. Due to the non‐stationarity of some variables, regressions are performed using first differences of variables. Secondly, lags are introduced into the Feder model. The statistical results are highly improved. Not only is a strong positive association between defence spending and economic growth found for Turkey, but also human capital is positively correlated to Turkish economic growth with a lag.  相似文献

In this paper, new data from the south west of England are used to illustrate that defence dependent firms are likely to purchase more inputs locally than less defence‐dependent firms. The results confirm that the defence industry's supply chain has unusual characterises and that defence industrial restructuring is therefore, likely to produce different outcomes to previous rounds of manufacturing restructuring.  相似文献

The Western European defence industry used to be characterized by numerous constraints, especially in the small countries, subject to uneconomic defence production policies. It faces, since the end of the Cold War, a succession of new challenges such as budget restrictions, armament reductions and geopolitical upheavals. The EU is pushing in the direction of a cohesive foreign policy, including security and defence. Today, the emergence of a more consolidated European defence industry and the presence of oligopolistic European companies imply the definition of new roles for the EU and for its European Security and Defence Policy (ESDP). The solution is not protectionism, but more co‐operation to ensure effective defence production at a socially acceptable cost. In the framework of this co‐operation, defence companies in small and medium countries have a role to play as part of the supply chain to major weapon system integrators.  相似文献

How have European cross-border defence industrial mergers and acquisitions affected domestic procurement bias among the major EU powers? This article departs from the findings of Andrew Moravcsik more than two decades ago suggesting that major West European states had no ingrained preferences for defence industrial autarchy. When cross-national armament projects were derailed, this could be attributed to political efforts of national defence industrial champions favouring purely domestic projects. As former national champions join pan-European defence groups, their preferences are likely modified. Does this shift procurement towards non-European “off-the-shelf” solutions which, according to Moravcsik, are favoured by defence departments? Or does it give impetus to a stronger preference for European as opposed to domestic systems? In this article, procurement patterns in the aftermath of cross-border defence industry consolidation will be analysed. Procurement bias is assessed in two industry segments characterised by pervasive consolidation.  相似文献

The electronics industry provides components and capabilities that are critical to modern defence requirements. It is anticipated that the effectiveness of both weapons systems and the command and control network that supports military operations will become increasingly dependent upon the electronics sub‐systems they employ in the future. With the ascendancy of ‘network centric warfare’, it seems certain that defence electronics will continue to grow in importance in the future, enabling far‐reaching advances in military capability and efficiency. Yet little is known about the structure, conduct, performance and competitiveness of the UK defence electronics sector as it prepares to meet the challenges ahead. This paper reports the findings of a study commissioned in 2002 by Intellect, the UK defence electronics trade association, and supported by the Department of Trade and Industry. The UK defence electronics industry is found to be a high technology, R&D‐intensive and decreasing cost industry, which is competitive in world defence markets. The UK industry faces major competitive threats in the future from established US and European firms and from potential new entrants from China, India, Israel, Singapore, South Korea and Turkey. The future competitiveness of the UK defence electronics industry will depend on maintaining both technical advantage and open access to the large US market.  相似文献

Most countries put significant amounts of time and effort in writing and issuing high-level policy documents. These are supposed to guide subsequent national defence efforts. But do they? And how do countries even try to ensure that they do? This paper reports on a benchmarking effort of how a few “best of breed” small- to medium-sized defence organisations (Australia, Canada, and New Zealand) deal with these issues. We find that most countries fail to link goals to resources and pay limited attention to specific and rigorous ex-ante or post-hoc evaluation, even when compared to their own national government-wide provisions. We do, however, observe a (modest) trend towards putting more specific goals and metrics in these documents that can be – and in a few rare cases were – tracked. The paper identifies 42 concrete policy “nuggets” – both “do’s and don’ts” – that should be of interest to most defence policy planning/analysis communities. It ends with two recommendations that are in line with recent broader (non-defence) scholarship on the policy formulation-policy implementation gap: to put more rigorous emphasis on implementation (especially on achieving desired policy effects), but to do so increasingly in more experiential (“design”) ways, rather than in industrial-age bureaucratic ones (“PPBS”-systems).  相似文献
