Background information: this excerpt is from elizabeth gaskell’s novel mary barton, describing life in manchester in the early 1800s. all that part of the town was comparatively old; it was there that the first cotton mills were built, and the crowded alleys and back streets of the neighbourhood made a fire there particularly to be dreaded. the staircase of the mill ascended from the entrance at the western end, which faced into a wide, dingy-looking street, consisting principally of public-houses, pawnbrokers' shops, rag and bone warehouses, and dirty provision shops. the other, the east end of the factory, fronted into a very narrow back street, not twenty feet wide, and miserably lighted and paved. –mary barton, elizabeth gaskell which social class do you think lived in the conditions described in the passage? middle class working class upper class agrarian class

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.
