The federal budget deficit acts as an automatic stabilizer because

tax revenues decrease during a recession

Explanation:

Automatic stabilizer refers to  policies to control the fluctuation in the economy

During a recession, the income that average people have would automatically decrease. Since  the amount of federal budget is reliant on the amount of income taxes

To stabilize this, the government reduce the amount of federal budget and let the people keep a larger portion of their money so they can invest it in their own business.

answer; i believe that the correct answer is ( troxel v. granville);

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.
