A country imports goods and services worth $700 million and exports goods
and services worth about $500 million. This means that the country has an)
a. trade surplus
b. trade deficit
c. comparative advantage
d. absolute advantage

Answers

Answer:

B. trade deficit

Explanation:

just did it on a-p-e-x

A trade deficit occurs when a country imports more goods and services than it exports. In this case, the country is importing goods and services worth $700 million and exporting goods and services worth about $500 million, indicating a trade deficit of $200 million. The correct option is b.

What happens with a trade deficit?

The salaries of domestic workers are lowered when there is a trade deficit, placing many of them in lower-income tiers. Saving money is typically far more difficult for low-income families. Decreases in national savings can and do result from growing trade imbalances.

A trade surplus, on the other hand, occurs when a country exports more goods and services than it imports.

Comparative advantage and absolute advantage refer to a country's ability to produce a particular good or service more efficiently than other countries. They are not directly related to trading deficits or surpluses.

Thus, the ideal selection is option b.

Should a Female with the same Qualifications as a Man, if selected for an Executive Position formerly held by a man, be paid the same salary as her counterpart prior to her?

Answers

Answer:

The simple answer is yes a female should be paid the same, but often this is not the case.

Explanation:

Morally, yes a female with the same qualifications and experience should be paid the same salary as the counterpart prior to her, though it is not a law that there can't be a wage gap between women and men and this is most commonly not a reality. Women are often paid less than men with the same degree, qualifications, and experience, especially if the woman is part of a racial minority, or in a male dominated industry. Often, employers are able to find loopholes and reasons, "justifying" this unjust wage gap.
