Answer:
B. All the above are included in GDP.
Explanation:
GDP is a measure of an economy’s total production and in most cases, it is used to determine how developed or how grown a certain economy is. To calculate the GDP, we take into consideration every form of production within the country. Factors such as consumption expenditure, private domestic investment, government spending, imports and exports are all determinants of GDP. Therefore, the sale of stocks and bonds, sale of services and the sale of used goods, collectively are included in calculation of GDP. Hence the correct answer is B.
Answer:
It is capital deepening (D)
Explanation:
Capital deepening typically represents an increase in the capital-labor ratio. This arises when there is infusion of additional capital(e.g technological improvement) into the production processes while work force is either kept constant or cut-down and thereby makes labor to be more productive.
Hence, as the capital-labor ratio increases, the marginal product of labor, i.e. the amount of product that can be produced by supplying one more unit of labor, increases because there are now more units of capital per worker.
