- How economic positive and negative impact of the war to higher military spending? Most models show that military spending to divert resources from productive uses, such as consumption and investment, and ultimately slows economic growth and reduces employment. So, it seems war causes disadvantages more than advantages to influence economy growth to any countries in possible.Some economists showed global insight produced a set of projections that compared a scenario with an increase in annual military spending equal to 1.0% of GDP current about $135billions relative to its baseline scenario . This is approximately equal to the increase in defense spending that has taken place compared with the pre-Sept. 11th terrorism Iraq war baseline to US government higher military spending. However, who also indicated military spending is not generally perceived to cost jobs. In standard economic models, war its positive impact can be thought of in the same way as spending on the environment from war bad influence. When tax and emission restrictions are often used to achieve environment protection during and after war. It is also possible to reach environmental targets by paying people to do things that will reduce pollution. For example, it is possible to reduce greenhouse gas emissions by paying people to buy more fuel efficient cars and appliances, or paying than to install insulation and other energy saving devices. So, during the war period, more greenhouse gas fuel efficient cars will increase demand in car market. Thus, war can reduce air and water pollution cost and encourage greenhouse gas fuel consumption. In the case of both increased military spending and paying people to take steps to reduce greenhouse gas emissions, resources would be reduced to supply to these countries' domestic market directed uses. In standard economic models, war it's negative impact to this redirection of other resources, due to the original resources are used to increase military spending to manufacturing any new weapons and it will cause this original resources are shortage to prepare for these countries' manufacturing countries. So, these resources shortage challenges will cause these military spending countries' economy to operate less efficiently and therefore lead to slower growth and fewer jobs supplies. Thus, war will bring resource shortage challenges and fewer jobs supplies bad influence. In policy debates, it is important to recognize the potential jobs losses are caused from military spending factor mainly. Also the potential economic costs are often a factor in debates over environment policy.
