In Piaget's theory, the stage of cognitive development between 7 and 11 years of age, in which an individual becomes capable of logical thought processes but is not yet capable of abstract thinking, is the stage.

Concrete Operational stage

Explanation:

The concrete operational stage represents the third stage in the cognitive development theory of Piaget. This period covers the length of middle childhood ,it starts about 7 years old and lasts until around 11 years old and is marked by the growth of critical thinking. This is the time of life when children start mental surgery, when you control the universe from your mind to resolve issues.

The child makes use logic to solve problems related to his or her own personal experience but has difficulty resolving hypothetical issues or addressing increasingly complex issues.

trade regulation is a field of law, often bracketed with antitrust (as in the phrase “antitrust and trade regulation law”), including government regulation of unfair methods of competition and unfair or deceptive business acts or practices. antitrust law is often considered a subset of trade regulation law. franchise and distribution law, consumer protection law, and advertising law are sometimes considered parts of trade regulation law.

in general the theory of economics says that the more open to trade a country is the better   the result for the same country and the whole economies.

in real life countries impose taxes, quotas, etc which is not so good for the economies.

this kind of commercial war between the usa and china is slowing down the growth of the whole world so we can say that it is a draw back of trade regulations. and the free trade agreements are benefits of trade regulations.
