In the market for widgets, the supply curve is the typical upward-sloping straight line, and the demand curve is the typical downward-sloping straight line. The equilibrium quantity in the market for widgets is 250 per month when there is no tax. Then a tax of $6 per widget is imposed. as a result, the government is able to raise $750 per month in tax revenue. we can conclude that the after-tax quantity of widgets is
125 per month

Allen tutors in his spare time for extra income. Buyers of his service are willing to pay $40 per hour for as many hours Allen is willing to tutor.

Assume Allen is rational in deciding how many hours to tutor. His producer surplus is

export copper, since that country has a comparative advantage in copper

the supply curve for whisky is the typical upward-sloping straight line, and the demand curve is the typical downward-sloping straight line. when whisky is taxed, the area on the relevant supply-and-demand graph that represents
governments tax revenue is a triangle, the deadweight loss of the tax is a triangle, and the loss of consumer surplus caused by the tax is neither a rectangle nor a triangle. (all of the above are correct)
if the labor supply curve is nearly vertical, a tax on labor

the infant-industry argument
is based on the belief that protecting industries when they are young will pay off later
"other things equal, when the price of a good rises, the quantity supplied of the good also rises, and then the price falls the quantity supplies falls as well." this relationship between price and quantity supplied
is referred to as the law of supply
When a surplus exists in a market, sellers
lower price, which increases quantity demanded and decreases quantity supplied, until the surplus is eliminated.
