What is the system of goods are bought and sold in Mexico?

Answer 1

Same way most products are produced, sold an distributed: they have to pass through a series of primary, secondary and tertiary businesses to reach the final consumer:

Primary industries extract, grow, hunt or fish the necessary materials to build or produce the final product. For example, for canned tuna the tin must be mined and the tuna has to be fished.

Secondary industries transform the raw material into various intermediate products. For example, a tin smelter will transform cassiterite mineral (tin oxide) into tin sheets and from there, into tin cans. Also, a secondary industry would process the fished tuna, adding some preservative ingredients for packaging. Finally, another secondary industry - a food processing plant - would take tin cans and processed tuna fish to pack them into canned tuna.

Tertiary businesses will then sell the finished product. An example of such business would be a supermarket.

Answer 2

Many are manufactured in factories and foreign-owned manufacturing plants called maquiladoras, others are made by handcraft work and are much more expensive due to labor costs. One example of manufactured products are automobiles, which are assembled on large plants located in cities such as Puebla (Volkswagen), Hermosillo (General Motors) or Aguascalientes (Nissan). Some examples of handcraft goods include rebozos, small wood kitchen utensils or wicker baskets.
