This paper investigates the causality issue between military expenditure and growth in the case of Turkey, a strategically located developing country, for the period 1954–1993. Results reported herein reveal the absence of any causal ordering between the variables in question. 相似文献

Although a number of studies concerning Turkish defence-growth relation have been published in recent years, little attention is given the demand for Turkish defence expenditure. This is an important issue for understanding which variables contribute to the determination of the demand for military expenditure. However, it is difficult to develop a general theory or a standard empirical approach for the determination of the demand military expenditure. This study models and estimates the demand for Turkish defence expenditure for the period 1951-1998 using autoregressive distributed lag approach to cointegration (ARDL) following the methodology outlined in Pesaran and Shin (1999). This procedure can be applied regardless of the stationary properties of the variables in the sample and allows for inferences on long-run estimates, which is not possible under alternative cointegration procedures. The findings suggest that Turkish defence spending is determined by NATO's defence spending, Greece's defence spending and some security considerations. 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

环境信息动态更新是分布式虚拟环境的一个主要特点,如何使环境信息更新更活跃、更反应实际情况,一直是分布式虚拟环境研究的重点。在典型的分布式交互环境中,环境信息动态更新是基于协议数据单元(PDU),它不提供数据可靠性传输保证。如何保证分布式环境中各结点环境信息一致性,本文提出了一种信息校验和协议,它通过极少的信息传输就可保证各结点环境信息高度一致。文中定义了保证分布式环境信息动态一致性更新的协议数据单元,并在试验环境中证明了协议的可靠性。 相似文献

In this paper we evaluate what terrorism policies have worked best in handling the Spanish ETA terrorism using time series data from 1968 to 2000. We consider the political, deterrence and economic effects, and conclude that their influence on terrorism incidents is mixed. A parsimonious model shows that the behaviour of different terrorism incidents is distinct and the lagged effect is a primary concern. A policy to manage this case is devised. 相似文献

The causal relationship between economic growth and defence spending has attracted considerable attention and has been the subject of many empirical studies. This paper investigates the existence of a causal link between military expenditure and economic growth in the case of Greece for the period 1955–93. By European Union standards, Greece allocates substantial human and material resources to defence. At the same time, Greece is the poorest European Union member facing chronic economic problems. Using the concept of Granger‐causality, the findings reported herein suggest that neither variable Granger‐causes the other disclosing thereof the absence of any causal ordering between them. 相似文献
