An extensive literature on the effect of military expenditures on economic growth yields conflicting results. However, a crucial issue that has not been investigated in this context is the possible effect of inequality. The impact of military expenditures on economic growth in Turkey has also received substantial attention. Yet, the majority of these studies are not constructed based on a structural model, but rather examine the causality between the variables in question. Considering these two shortcomings in the literature and the lack of consistent results, this study attempts to provide further evidence for the relationship between military expenditures and economic growth for the case of Turkey by considering income inequality within an augmented Solow growth model. Our findings for the 1963–2008 period show that while income inequality has a positive impact on economic growth, military expenditures have no significant effect. 相似文献

There are conflicting views as to the relationship between a nation’s defense expenditure (DE) and its population’s income inequality (INEQ). DE, always an important part of government budget, can easily crowd out transfer payments, necessary to improve INEQ; however, these payments may also create a demand that may raise the income levels of the lower income earners. Consequently, the relationship between DE and INEQ is an important question. This paper examines the relationship between DE and INEQ in China for the period of 1989–2012. Utilizing basic cointegration and causality tests, our objective is to add to the literature by providing evidence that China’s DE, in fact, do have an impact on INEQ. 相似文献

三维静磁场Lipschitz区域上Robin问题广义解的存在与唯一性 总被引:2,自引:1,他引:1
近年来,电磁场边值问题的数值解法取得了飞速的发展.由于电磁场边值问题是一类非线性偏微分方程,研究解的存在性、唯一性具有较大的困难.前人已讨论了B-H间的几个基本不等式,并由之证明了三雏静磁场带零边值问题广义解的存在与唯一性,作者也曾利用给出的B-H间的不等式证明了三维静磁场Neumann问题和二维时变场第一边值初值问题广义解的存在与唯一性.由于在一般区域讨论存在困难,作者利用Sobolev空间理论及单调算子理论证明了三雏静磁场Lipschitz区域上Robin问题广义解的存在与唯一性. 相似文献

The rising trend in income inequality has recently attracted a renewed interest in the determinants of this growing trend across many countries. This article adds to the debate by investigating the impact of defence expenditure as a possible determinant of inequality in Taiwan, a country once was considered to be a poster child of an equitable growth, but now income inequality has become one of the Taiwan’s growing challenges. Applying the bounds test approach to cointegration and four long-run estimators for the period from 1976–2011, we found a long-run relationship between the various measures of inequality and defence expenditure where defence expenditure exerts a positive and a statistically significant impact on the worse income inequality in Taiwan. Further application of the lag-augmented causality test procedure also reveals a unidirectional causality running from defence expenditure to income inequality with defence expenditure causing income inequality to rise. 相似文献
