This article reports the results of experiments undertaken using a global economy-population-resources model to examine the future of trade in raw materials between the rich and poor countries of the world. The model is a variation of a previous model that examined the impact of resource scarcity on the global economy in aggregate. As identified in the previous article, and various other studies, the world faces resource scarcity in the coming century under business-as-usual economic conditions, resulting in at least some degree of economic and population collapse. The impact of these circumstances on the poorer countries, whose endowment of resources is small compared to the rich world, is exacerbated if trade in raw materials declines as scarcity increases. Significant improvements in resource efficiency and a rapid reduction in fossil fuel combustion are required to avoid collapse, maintain a viable economy and improve average living standards across the world. Retaining global trade in resources is necessary to ensure the poorer countries can make this transition, but may not be sufficient to ensure the future of the (presently) lowest income countries.
