A large literature has used tests for Granger (1969) non‐causality, GNC, to examine the interaction of military spending with the economy. Such tests answer a specific although quite limited question: can one reject the null hypothesis that one variable does not help predict another? If one can reject, there is said to be Granger causality, GC. Although the limitations of GNC tests are well known, they are often not emphasised in the applied literature and so may be forgotten. This paper considers the econometric and methodological issues involved and illustrates them with data for the US and other countries. There are three main issues. First, the tests may not be informative about the substantive issue, the interaction of military expenditure and the economy, since Granger causality does not correspond to the usual notion of economic causality. To determine the relationship of the two notions of causality requires an identified structural model. Second, the tests are very sensitive to specification. GNC testing is usually done in the context of a vector autoregression, VAR, and the test results are sensitive to the variables and deterministic terms included in the VAR, lag length, sample or observation window used, treatment of integration and cointegration and level of significance. Statistical criteria may not be very informative about these choices. Third, since the parameters are not structural, the test results may not be stable over different time periods or different countries. 相似文献

We have used the Michigan Model of World Production and Trade to assess the impact of exports and imports of armaments (based on 1980 data) on sectoral trade and employment and other economic variables in the major Western trading countries. If the United States were to place a unilateral embargo on its arms exports and imports, we calculate that it would experience a comparatively small amount of employment displacement in the aggregate and that most of this displacement would occur in the transport equipment and electric machinery sectors. If all the major Western countries were to place a multilateral embargo on their arms trade, the sectoral effects on the United States would be similarly small. But the sectoral effects in several other industrialized and developing countries measured as a percentage of sectoral employment, would be larger, indicating potential short‐run adjustment problems in labor markets in some cases. 相似文献

The Australia Group's (AG's) contributions toward stemming global proliferation of chemical and biological weapons of mass destruction over the last 20 years are noted, in addition to the group's complementary role in effectively supporting the purpose and objectives of the Chemical Weapons Convention (CWC). This report also outlines the organizational and operational means that help accomplish the AG mission and notes the U.S. Congress’ recognition of the role of the AG in countering chemical and biological weapons proliferation. Addressing criticism by some CWC states parties that question the AG's role in nonproliferation, the author also highlights the AG's expanded reach since September 2001 over terrorist activity. Finally,the article identifies a challenge the AG now faces in furthering its objectives and offers a possible solution. 相似文献

Scholarly research and publication in many countries has made the Korean War not only remembered, but also better understood. Material from Russia and China have been especially helpful in adding nuance and detail to now‐dated writing about the war's causes. Much more work needs to be done on Korean politics and the 1952–53 period, but in all the scholarship simply confirms the shared responsibility of all the belligerents ‐ including the Koreans ‐ in starting and continuing the war. 相似文献

Despite all the talk of ‘hearts and minds’ being the key to counterinsurgency, local public opinion is rarely studied and when it is, it often yields surprising conclusions. Through analyzing polling data from Vietnam, Iraq and Afghanistan, this article shows that public opinion is less malleable, more of an effect rather than a cause of tactical success, and a poor predictor of strategic victory. As a result, modern counterinsurgency doctrine’s focus on winning popular support may need to be rethought. 相似文献
