There is as yet insufficient data for a meaningful answer. As world peace has not been achieved, the conditions necessary to achieve it have not and cannot be studied.

It is possible that if world peace is eventually achieved, it will happen under a different economic system than the one that is currently dominated. It is important to note, however, that war has occurred under many different economic systems. Therefore, there is no reason to believe that changing from capitalism to an alternative economic system will necessarily result in world peace.
