Rhetorical question in economics?

Question

I was reading this economy book, and there were these question at the end of the book ... and i found two interesting question that i thought to get others opinion about them.

1. All countries exports – All countries imports =???
"its an equation"

2. Can a market be deregulated??

Answer 1

1. if we're talking about exports in good form...

goods/services a country ships out --- goods/services a country recieves.

YOU SEE HOW MUCH THE COUNTRY IS DEPENDENT ON OTHER COUNTRIES FOR OTHER GOODS AND SERVICES OR WHETHER IT IS ABLE TO PRODUCE THEM ALL BY ITSELF (WHICH IS PRETTY MUCH IMPOSSIBLE)

2. By certain factors, of course.

Answer 2

All countries export - All countries imports = 0 (zero)
This is called Law of Conservation of Wealth. When wealth changes from one form to another, value of transferor form of wealth equals value of transferee form of wealth and that wealth can neither be created nor be destroyed but can be changed from one form to another.
Value of Exports = Value of imports.
2. Markets can be deregulated.

Answer 3

1balance of trade or trade surplus when >0 and trade deficit <0

2 Not completely. markets don't work well without rules and institutions to enforce the rules, It was tried in Russia.
