Explanation:

The "Little Albert" experiment was a controlled experiment that took place at John Hopkins University in 1920. This experiment tried to establish whether classical conditioning could be used to condition a child to fear a stimulus that normally would not be feared by a child. The experiment wanted to demonstrate that it was possible to condition an emotional reaction to a previously neutral stimulus. Although the experiment was considered to have been successful at the time, it has been criticized in recent years.

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.
