A marked trend in virtually every country in the Americas is the consolidation of many retailers, formerly known as grocery stores or corner stores, into fewer and larger supermarket chain corporations.
Describe that transition for the United States.
What possible sources of economies of scale allow these large corporations to obtain lower average costs?
Why has the horizontal limit of the average company in this retail category been expanded?

Another trend marked in practically every country in the Americas is the greater coordination between various agri-food companies that are dedicated to the different stages of a production chain.
How to describe for the United States and the pork industry, these processes in which the vertical limits of the company expanded?
What are some reasons that may have motivated this greater vertical integration?
In economics, it is said that there are economies of scope (scope) when more is earned by doing two economic activities under the same company, than what would be earned in the aggregate if these activities were carried out by different companies.
Like the United States and the chicken meat industry, have they taken advantage of the existence of economies of scope?

Provide examples if possible and sources of information, thanks!
