This is an example of a. social loafing.

Explanation:

Social loafing is a term used in social psychology to describe a phenomenon that takes place when individuals working is group exert less effort than they would if working on their own. Groups are, sometimes, less efficient and less productive because of this phenomenon. Some people tend to think their effort is not necessary since others will be working hard. They do not feel responsible for how productive their actions will be any longer. That is precisely the case with Tom. The reason why he does not contribute is because he is certain that the others can handle it all by themselves.

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.
