ABSTRACTDo democracies spend less on national defense? This paper provides new evidence of the effect of democracy on defense burden based on a Spatial Durbin Model with panel data for 98 countries for the years 1992–2008. While democracy measured by means of an index variable covering the entire range from perfect democracy to perfect autocracy turns out to be insignificant, dummy variables indicating transition to higher levels of democracy reveal a statistically highly significant negative effect of democracy on a country’s defense burden. Allowing for country-specific effects reveals heterogeneity in the effect of democracy across countries. Apart from the effect of democracy, the estimation results indicate strong spatial dependence of military burdens across countries. Moreover, they provide statistical evidence for a peace dividend, for substitution effects in defense spending and for a negative effect on the military burden for countries when they exhibit a trade surplus instead of a trade deficit. 相似文献

AbstractThe outbreak of the sovereign debt crisis at the end of 2009 in Greece led to a severe recession, and constant economic problems. This paper investigates military expenditure among others as a potential factor to the growth of sovereign debt in Greece over the period 1960 until currently. Our empirical findings suggest that high deficits, inflation and military spending have been the primary causes of debt growth in Greece. The structural break models reveal a much higher effect of deficits and inflation in the post-1990 period while the threshold switching regression, based on the level of sovereign debt, indicate that for levels of debt-to-GDP ratio above 90% deficits, inflation and military expenditures had significantly more pronounced effects on government debt changes. 相似文献

The effect of military expenditure on employment is a matter of considerable importance. However, few of the standard economic analyses of unemployment take any explicit account of variations in military expenditure in their models. The purpose of this paper is to assess whether the prevalent neglect of this variable in labour economics is justified. The paper briefly surveys previous estimates made of the employment effects of military expenditure. It then considers evidence from the simple dynamic reduced form regressions estimated on long historical series for the US and the UK and pooled post‐war data for 11 OECD countries. It does not suggest that the share of military expenditure is a significant influence on the unemployment rate. This implies that in analysing unemployment no special account need be taken of military expenditure and that the fear that reductions in the share of military expenditure will be associated with higher average unemployment levels is misplaced. 相似文献

舰艇近区安全防卫系统分析 总被引:1,自引:0,他引:1
针对我国舰艇近区安全存在的问题,参照国外舰艇近区自卫装备发展情况,提出了发展具有综合利用观瞄设备和声纳,并集合各种致命和非致命武器特点的舰艇近区安全防卫系统的构想。系统配备的观瞄设备用于探测地面、水上及低空近临目标,而声纳用于探测水下目标,如蛙人,无人水下航行器等。在打击方面,系统配备了可以歼灭目标的致命武器以及用于驱逐目标的非致命武器。并对系统的关键技术进行了初步探讨。
