what was the role of trade in the olmec civilization
Olmec The wide diffusion of Olmec artifacts and "Olmecoid" iconography throughout much of Mesoamerica indicates the existence of extensive long-distance trade networks. Exotic, prestigious and high-value materials such as greenstone and marine shell were moved in significant quantities across large distances. Some of the reasons for trade revolve around the lack of obsidian in the heartland. The Olmec used obsidian in many tools because worked edges were very sharp and durable. Most of the obsidian found has been traced back to Guatemala showing the extensive trade.[87] While the Olmec were not the first in Mesoamerica to organize long-distance exchanges of goods, the Olmec period saw a significant expansion in interregional trade routes, more variety in material goods exchanged and a greater diversity in the sources from which the base materials were obtained.
Economics Theory and observation set out the conditions such that market prices of outputs and productive inputs select an allocation of factor inputs by comparative advantage, so that (relatively) low-cost inputs go to producing low-cost outputs. In the process, aggregate output may increase as a by-product or by design.[37] Such specialization of production creates opportunities for gains from trade whereby resource owners benefit from trade in the sale of one type of output for other, more highly valued goods. A measure of gains from trade is the increased income levels that trade may facilitate.[38]
