Wealth dynamics in world trade

The focus of this paper is on the redistribution of multiple countries' wealth caused by these countries' internal wealth growth as well as the exports and imports between them. We have analyzed these countries' wealth using the gross domestic products (GDP) of about 190 countries from 1950 to 2000 and their world trade records to identify their internal wealth growth. It is shown that the internal wealth growth is more crucial in order to increase total wealth than exports and imports. This is shown as a function of wealth. We simulate an agent-based model including these features and find that a broad wealth distribution can emerge using internal wealth growth and an asymmetric money flow.
