Natalie, a location scout, has been very busy with work and noticed her cell phone is breaking down. She likes her old Pamsung phone but needs to get one that has faster network abilities, is not more than two hundred dollars, has international roaming capabilities, and is water-resistant if possible. She thinks maybe the latest Phonei would work, but then she realizes the most important criteria are water resistance and international roaming. After visiting five stores and spending countless hours online researching the various phones, she evaluates her options and decides to go with the Yons Aperix Z3v. She buys the phone and sets out to find her latest movie location. What decision model did Natalie use to pick her new phone

rational decision making

Explanation: The essence of rational decision making is to come up with a decision where the total benefit one tend to get is greater than or equal to their total cost. It is a systematic process of defining problems, evaluating alternatives and choosing optimal solutions (in this case, Natalie chooses Yons Aperix Z3v over other options).

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.
