Tariff
A tariff is called an optimal tariff if it's set to maximize the welfare of the country imposing the tariff. It is a tariff derived by the intersection between the "trade indifference curve" of that country and the offer curve of another country. In this case, the welfare of the other country grows worse simultaneously, thus the policy is a kind of "beggar thy neighbor policy". If the offer curve of the other country is a line through the origin point, the original country is in the "condition of a small country", so any tariff worsens the welfare of the original country.
Tariff of 1832
Enacted on July 13, 1832, this was referred to as a protectionist tariff in the United States. The purpose of this tariff was to act as remedy for the conflict created by the Tariff of 1828. Mainly, the protective Tariff of 1828 was created in such a way that it intended to protect the industry in the north. Because of this, the Tariff of 1828 was also called the Tariff of Abominations by Southern states as it seemed unfair on the part of the government to favor the North by sidelining the south. As compared to the hype created about the protective Tariff of 1832, it proved to be a far cry from fulfilling the demands of the south. Its predecessor pushed the duties on citizens which were as high as 45 percent on the value of specific manufactured goods, while 1832 act brought it down to 35%. For instance, the duty on hemp, which had been $60 a ton in 1828, was reduced to a duty of $40, as a result of compromise Tariff of 1832. Even then southerners were not happy with it. Eventually, their unrest and dissatisfaction was what led to the nullification crisis. Along with that, another bill was passed, Tariff of 1833.
