Explanation:

In general, psychologists  with a scientific purpose research, should act according to ethical principles, being familiar with the appropriate literature and take undertake procedures that are not going to produce any pain in the chosen animals for the study. Animals´ use in a research may not be conducted until the protocol has been reviewed by an Institutional Animal Care and Use Committee (IACUC) that ensures appropriate procedures and it to be the best suited to fulfill the clear scientific purposes of the research, increase knowledge and understanding of the process underlying the evolution of the species under study ,development, maintenance, alteration, control, or biological significance of behavior.

The psychologist should monitor the subjects’ welfare throughout the course of the investigation to ensure continued justification for the research and provide results that benefit the health or welfare of humans or other animals.

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.
