Ps1 All The Questioni National Income Accounts Suppose An Economys
Suppose an economy’s national accounts are as follows: GNP = 100, C = 70, I = 40, G = 20, and EX = 20. GNP is gross national product, C is consumption, I is investment, G is government spending, and EX is exports. Using the national income identity, find the value of imports (IM). What is the current account balance? What is the (economy-wide) savings rate? What would the government, private, and total savings rates be if the government reduced taxes T = 10 while the other variables remain unchanged.
Paper For Above instruction
The analysis of national income accounts offers vital insights into the economic health and balance of an economy. In this context, with given data points such as Gross National Product (GNP), consumption (C), investment (I), government spending (G), and exports (EX), we can compute various key economic indicators, including imports, current account balance, and savings rates. This paper discusses each of these calculations systematically and evaluates the implications of a tax reduction on savings behavior within the economy.
Calculation of Imports (IM)
The national income identity provides framework equations linking different parts of an economy. For an open economy, the flow of goods and services is represented as:
\[ GNP = C + I + G + (EX - IM) \]
where IM stands for imports. Rearranging the equation to solve for IM gives:
\[ IM = C + I + G + EX - GNP \]
Plugging in the known values:
\[ IM = 70 + 40 + 20 + 20 - 100 \]
\[ IM = 150 - 100 \]
\[ IM = 50 \]
Thus, the value of imports (IM) is 50 units.
Current Account Balance
The current account balance reflects the difference between exports and imports, along with other income flows. Given the data:
\[ Current\,Account = EX - IM \]
\[ = 20 - 50 \]
\[ = -30 \]
A negative current account balance of -30 indicates a deficit, implying the economy is importing more than it is exporting by this amount. This deficit has implications for the country’s foreign debt and overall economic sustainability.
Economy-wide Savings Rate (S/Y)
Savings in an economy is generally defined as income not spent on consumption:
\[ S = GNP - C \]
Using the provided data:
\[ S = 100 - 70 = 30 \]
The savings rate (S/Y) is calculated on the basis of gross national income:
\[ \text{Savings Rate} = \frac{S}{GNP} = \frac{30}{100} = 0.3 \quad \text{or} \quad 30\% \]
This indicates that 30% of the gross national income is saved within the economy.
Impact of a Tax Reduction on Savings Rates
Suppose the government reduces taxes (T) by 10 units, with all other variables held constant. The government budget constraint is:
\[ T = 10 \]
Since taxes are reduced, disposable income for private agents increases, which could influence saving and consumption behaviors. The new disposable income \( Y_D \):
\[ Y_D = GNP - T = 100 - 10 = 90 \]
Assuming consumption function remains unchanged (though in practice, this may vary), with C = 70 initially, the extra disposable income can either be saved or spent. However, in the baseline, consumption was close to 70, so to analyze the effect:
- If consumers maintain the same pattern, then private savings \( S_{private} \):
\[ S_{private} = Y_D - C \]
\[ = 90 - 70 = 20 \]
- The government’s savings (or surplus):
\[ S_{government} = T - G \]
\[ = 10 - 20 = -10 \]
which indicates a budget deficit from the government sector.
- Total savings, considering the entire economy:
\[ S_{total} = S_{private} + S_{government} \]
\[ = 20 - 10 = 10 \]
As a result, the overall savings rate would change accordingly:
\[ S_{total} / GNP = 10 / 100 = 0.1 \text{ or } 10\% \]
This suggests that reducing taxes increases private savings but decreases the government’s savings, leading to a net reduction in total savings and affecting investment and economic growth prospects.
Concluding Remarks
The calculations demonstrate the interconnectedness of national income components and the significant impact government policy measures, such as taxation, can have on savings, the current account balance, and overall economic stability. Maintaining a sustainable current account deficit and fostering savings are essential for long-term economic health, especially in open economies involved in global trade. Policymakers need to balance tax policies with the overarching goal of fostering a stable macroeconomic environment conducive to sustainable growth.
