Explain the difference between gross investment and net investment. Why is net investment used instead of gross investment in computing net national product? Explain the problem of double counting and how it may be avoided.

Short Answer

Expert verified
Gross investment is the total amount invested in assets and capital goods without considering depreciation, while net investment accounts for depreciation, representing the net increase in capital stock. Net investment is used in computing net national product because it accurately reflects the increase in an economy's capacity for production, whereas gross investment may overestimate the productive capacity by ignoring depreciation. Double counting is an error where the value of a good or service is counted multiple times in economic measures. To avoid double counting, the value-added approach is used in calculating GDP, which only considers the value added by each producer within the production chain, ensuring intermediate goods are not counted more than once.

Step by step solution

01

Define Gross Investment

Gross investment is the total amount of investment made by a business or an economy in a given period, without considering depreciation. It includes all expenditures towards the purchase of capital goods, infrastructure development, business expansion, and the acquisition of new technological capabilities.
02

Define Net Investment

Net investment is the difference between gross investment and depreciation. Depreciation is the decrease in the value of any asset over time due to wear and tear, obsolescence, or other factors. Net investment measures the actual increase in the total amount of capital stock, capturing the net growth of assets in a given period.
03

Highlight the Difference Between Gross Investment and Net Investment

The difference between gross investment and net investment lies in the consideration of depreciation. Gross investment represents the total amount invested in assets and capital goods without considering their depreciation, while net investment takes into account the loss of asset value due to depreciation, representing the net increase in capital stock.
04

Explain Why Net Investment is Used in Computing Net National Product

Net investment is used in computing net national product because it accurately reflects the increase in an economy's capacity for production. By accounting for depreciation, net investment measures how much new capital is added to the economy, which is essential for determining an economy's overall productivity growth. Gross investment, on the other hand, may show high values even if the economy's productive capacity is not growing, as it ignores depreciation, which reduces the actual value of assets over time.
05

Define the Problem of Double Counting

Double counting refers to the error that occurs when the value of a good or service is counted more than once in the process of calculating a country's GDP or other economic measures. This usually occurs when intermediate goods (goods that are inputs to the production of other goods) are included in the final output, leading to an overestimation of the total output.
06

Explain How Double Counting May Be Avoided

To avoid double counting, economists use the value-added approach in calculating GDP. This method takes into account only the value added by each producer within the production chain. The value-added approach involves counting the value added by each stage of production and summing these values, which ensures that intermediate goods are not counted more than once in the calculation of the final output. As a result, it provides a more accurate measure of economic output and helps eliminate the problem of double counting.

Define Gross National Product (GNP).

Explain how inflation and deflation complicate the computation of the gross national product.

The following data provides a "real-world" illustration of adjusting GNP for changes in the price level (selected years, in billions of dollars). $$ \begin{array}{cccc} \text { Year } & \begin{array}{l} \text { Money, or } \\ \text { unadjusted GNP } \end{array} & \begin{array}{c} \text { Price level } \\ \text { index, percent } \end{array} & \begin{array}{c} \text { Adjusted } \\ \text { GNP } \end{array} \\ 1946 & \$ 209.6 & 44.06 & ? \\ 1951 & 330.2 & 57.27 & ? \\ 1958 & 448.9 & 66.06 & ? \\ 1964 & 635.7 & 72.71 & ? \\ 1968 & 868.5 & 82.57 & ? \\ 1972 & 1,171.5 & 100.00 & ? \\ 1974 & 1,406.9 & 116.20 & ? \\ 1975 & 1,498.9 & 126.37 & ? \end{array} $$ Determine the adjusted GNP for each year.

Suppose the following data are available for an economy (figures in billions of dollars) \- Compensation of Employees 642 \- Income Taxes 116 \- Capital Consumption Allowances 95 \- Income other than Compensation of Employees 209 \- Indirect Taxes 101 \- Net Investment 152 Further, it is known that there are no corporations, and all income is paid directly to persons; there are no transfer payments, there is a balanced budget; and government expenditure is exclusively on the provision of services to the economy. Calculate each of the following: 1\. Gross National Product (GNP) 2\. Net National Product (NNP) 3\. National Income (NI) 4\. Personal Income 5\. Disposable Personal Income 6\. Government Sector Gross Output 7\. Private Sector Gross Output 8\. Consumption Expenditure 9\. Gross Investment
