While giving a lecture at Peking University, Mohnish Pabrai mentions a mental model used by Guy Spier

​

If Guy Spier identifies a great business in the USA, or any specific country, he then searches for the same type of business in other countries.

​

If Guy discovers that Coca-Cola bottlers in the USA are great businesses, he will go look for other Coca- Cola bottlers in other countries .

​

This helps him screen for quality businesses a lot more easier.
