1. A country’s ____ is the market value of all final goods and services produced within the country’s borders in a given time period.

1. Gross Domestic Product
2. Gross National Product
3. Net Domestic Product
4. National Income

1. Let a country’s net receipts of factor income from the rest of the world = income earned by the permanent residents of the country for work done abroad by them or with resources owned by them minus income earned by the permanent residents of other countries for work done in the country by them or with resources owned by them. Then

1. GNP = GDP + net receipts of factor income from the rest of the world
2. GDP = GNP + net receipts of factor income from the rest of the world
3. Exports – Imports = net receipts of factor income from the rest of the world
4. GNP = GDP + Exports – Imports
5. GDP = GNP + Exports – Imports

1. As in the textbook, let Y stand for GNP, C for consumption spending, I for investment spending, G for government purchases, EX for exports, IM for imports, and CA for the current account balance. Then

1. Y = C + I + G.
2. Y = C + I + G + EX + IM.
3. Y = C + I + G + EX – IM.
4. Y = C + I + G – CA.

1. Let T be the net tax revenues of the government. That is, T = tax revenues – transfer payments (such as, pensions for retirees, unemployment benefits, cash grants for poor people, etc.). Then, National Saving (S) is defined as

1. S = Y – (C + I + G)
2. S = Y – C – G
3. S = T – G
4. S = Y – T – C.

1. Private Saving (Sp) is defined as

1. Sp = Y – (C + I + G)
2. Sp = Y – C – G
3. Sp = T – G
4. Sp = Y – T – C.

1. Public Saving (Sg) is defined as

1. Sg = Y – (C + I + G)
2. Sg = Y – C – G
3. Sg = T – G
4. Sg = Y – T – C.
