Scientific Model

Explanation:

A scientific model is a common term in scientific experimentation or research, which is used to describe a particular phenomenon or situation, by using something else to represent it, thus, it helps in understanding the concept in a easier way.

A scientific model are in various forms, such as visual model, mathematical models or computer models.

The purpose of scientific model is to make the actual thing, phenomenon or situation that is being modelled easier to understand. This helps in using the model to understand how and why a situation occurs, and predict what happens in future.

For example, using predictive models, to predicting or make weather forecast, that is what will happen as our climate changes would be easier to understand, if we could make a fully accurate model of the atmosphere.

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.
