The Effects of Defence Spending Reductions: A CGE Estimation of the Foregone Peace Dividend in the Case of Greece

With the collapse of bipolarity and the end of the East-West armaments race, defence budgets have shrunk and military expenditures across many countries have fallen, opening-up the prospect of potential beneficial economic spin-offs. In the case of Greece, a country with a higher than average defence burden, military spending has not exhibited similar downward trends as it has done in other members of NATO and the European Union. The paper, using a Computable General Equilibrium model, estimates through simulations the effects on the Greek economy had reductions in current defence spending been equal to the NATO average. The results from the CGE estimations suggest that a shift of expenditure from defence into non-defence public spending would have an appreciable beneficial impact.     

Defence R&D expenditure: The crowding-out hypothesis

The impact of defence expenditure on the economy has been widely studied through different types of models. However, the results from these studies have not reached definitive conclusions, and have left a gap in the analysis of the impact of defence R&D expenditure at the economy level. Defence R&D has specific characteristics, which lead to market failures: public good, high risk and uncertainty, national security. Also, defence R&D creates two types of externalities: negative (crowding-out), and positive (spin-off). Crowding-out is the major economic debate about defence R&D. This paper analyses the crowding-out hypothesis by applying three types of models for the UK case: supply, demand, and demand-supply models. From these three models the most reliable is chosen and applied to the individual cases of France, Germany, Japan and USA. The paper also reports the results for the pooled data of these five countries, and for four error component models. The results from estimating such models shed light on the defence R&D crowding-out hypothesis.     

Using the Feder-Ram and Military Keynesian Models to Examine the Link Between Defence Spending and Economic Growth in Sri Lanka

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.

A survey of performance issues in defence innovation

This article reviews innovation processes in defence. It analyses the way and the context under which these processes are carried out. The article covers the features of defence goods with impact on innovation, the development of a new good, the institutional arrangements that support these processes and the effect of innovation on industrial market. The analysis helps to identify the causes of facts observed in practice, such as poor performance in terms of product quality, cost or delivery time, as well as to assess potential remedies. Some policy implications, which can be derived from this analysis, are finally outlined.

语言测试的反拨效应与英语测试改革的几点建议

目前,我国英语测试种类繁多,并对教学产生了一些负面影响,致使英语教学存在着一定的应试倾向,而语言测试的正反拨效应,即以测试促进教学的作用却没有得到充分体现。如何使测试对教学起到促进作用,解决此问题的关键就是修改英语测试的题型,使题型多样化,尽量采用能考查学生语言应用水平的题型,并增设英语口语水平测试。通过语言测试的正反拨效应促进英语教学,提高英语教学质量。

略论国防专利在专利制度中的优先性

通过摘取法律法规中体现国防专利优先性的法律规范,阐明国防专利分别在国防专利申请阶段和国防专利实施阶段的优先性。对国防专利在专利制度中的优先性进行法理学分析,从国内国防建设的角度论证国防专利优先性的原因,通过研究美国和俄罗斯的国防专利制度来分析国防专利具有一定优先地位的合理性。文章对我国国防专利在专利制度的优先性提出发展建议,在国防专利申请阶段,国防专利要加大对国防专利权人的补偿力度,同时设立专门机构对普通专利进行国防专利审查。国防专利实施阶段要完善定密解密制度,发挥市场在国防专利向普通专利转换中的关键作用。
