Question 1consider The Following Economy Consisting Of 3 Industryener

Question 1 Consider the following economy consisting of 3 industry: Energy, Farming, Candy. The data provided includes total sales, wages paid, profits, and inputs for each industry. The task is to calculate the Gross Domestic Product (GDP) using three different approaches: the value of final goods approach, the value-added approach, and the income approach.

Additionally, there are questions about an economy with three sectors: mining and farming; manufacturing; and retailing. The details involve sales, inputs, and transactions between sectors, and the goal is to compute the value added in each sector and the total output.

Finally, there is an inquiry on how activities of criminals are treated in GDP accounting, as well as the treatment of police activities.

Paper For Above instruction

Gross Domestic Product (GDP) serves as a fundamental indicator capturing the economic performance of a nation. It measures the total value of goods and services produced within a country during a specific period. Understanding how to accurately calculate GDP is crucial for economic analysis, policymaking, and comparison over time and across countries. This paper explores three approaches to calculating GDP— the value of final goods approach, the value-added approach, and the income approach—by applying them to a simplified economy comprising three industries: energy, farming, and candy. Additionally, it discusses sectoral contributions in a different economy with mining and farming, manufacturing, and retailing sectors, and finally examines the treatment of illicit activities and law enforcement in national income accounting.

Part 1: Calculating GDP for the Three-Industry Economy

Given the data:

  • Energy: Total Sales = 2400, Wages Paid = 1400, Profits = 800, Energy Inputs = 600
  • Farming: Total Sales = 2200, Wages Paid = 1200, Profits = 400, Farming Inputs = 400
  • Candy: Total Sales = 3000, Wages Paid = 1200, Profits = 600, Farming Inputs = 200

a. Value of Final Goods Approach

This approach calculates GDP by summing the value of final goods and services sold to the end consumers, avoiding double counting. We identify the final sales in the economy. Since total sales are often given, and some are intermediate, the key is to determine final sales. If all sales presented are final, then GDP equals the sum of the final sales. Alternatively, if the total sales of each industry include intermediate transactions, then the GDP corresponds to the sum of the final outputs—usually the sales of goods to the end-users. Assuming the figures provided are total sales for final consumption, the GDP is the sum of sales of all three industries:

  • Energy: 2400
  • Farming: 2200
  • Candy: 3000

Thus, GDP (final goods approach) = 2400 + 2200 + 3000 = 7600.

b. Value Added Approach

Value-added in each industry is calculated as the industry's total output minus the inputs purchased from other industries or inputs used. Here, inputs are specified as energy inputs and farming inputs, which contribute to intermediate costs. The value added for each industry is:

  • Energy: Sales (2400) - Inputs (600) = 1800
  • Farming: Sales (2200) - Inputs (200) = 2000
  • Candy: Sales (3000) - Inputs (assumed part of farming/energy inputs; in this case, farming inputs were used in candy production, so the inputs specific to candy are 200 from farming), but to avoid misinterpretation, total inputs are added up separately. Since only farming inputs are specified for candy as 200, and farming inputs are allocated to the candy production, then actual calculation would consider that the inputs to candy are part of the farming input, which is 200. Therefore, we could consider the value-added as:
    • Candy: 3000 (sales) - 200 (inputs from farming) = 2800

Adding these, total value added (GDP) is 1800 + 2000 + 2800 = 6600.

c. Income Approach

This approach sums wages, profits, and other income generated. Given data:

  • Wages paid:
  • Energy: 1400
  • Farming: 1200
  • Candy: 1200
  • Profits:
  • Energy: 800
  • Farming: 400
  • Candy: 600
  • Economic rents or other income are not specified, so the sum of wages and profits approximates GDP:

GDP (income approach) = total wages + total profits = (1400 + 1200 + 1200) + (800 + 400 + 600) = 3800 + 1800 = 5600.

Part 2: Sectoral Value Added and Total Output in a Three-Sector Economy

In this scenario, the key variables are as follows:

  • Manufacturers produce goods worth 500; they sell 400 to retailers and 100 directly to consumers and government.
  • Retailers buy 400 from manufacturers and 50 from agriculture; they sell goods for 500 to consumers.
  • Farmers sell 100 directly to households; farmers buy 200 from other sectors.

Calculating value added:

  • Manufacturing sector:
  • Sales from manufacturing: 500
  • Input purchases: 200 from the agricultural and mining sectors
  • Value added = Output (sales to retailers and direct consumers) - intermediate inputs (200) = 500 - 200 = 300
  • Retailing sector:
  • Sales: 500
  • Input from manufacturing: 400
  • Input from farming: 50
  • Value added = 500 - (400 + 50) = 50
  • Farming sector:
  • Sales: 100 (direct to households)
  • Inputs purchased: 200 from other sectors (assumed to be inputs purchased by farmers, e.g., seed, equipment)
  • Value added = 100 (sales) - 200 (inputs purchased) = -100. However, a negative value indicates that the farming sector is only a part of the activity, or possibly that the inputs are out of the sector's scope here. For simplicity, assuming the primary contribution is the direct sale of 100, the sector's value added is 100.

The total output of the economy is sum of sectoral outputs:

  • Manufacturing: 500
  • Retailing: 500
  • Farming: 100

Total output = 500 + 500 + 100 = 1100.

Part 3: Treatment of Criminal Activities and Police Activities in GDP Accounting

Illegal activities, such as criminal enterprises, pose unique challenges in national income accounting. Traditionally, GDP aims to measure legitimate economic activity within the formal economy. As such, illegal activities like drug trafficking, illegal gambling, or other criminal enterprises are generally excluded from official GDP figures because they are not reported, taxed, or accounted for in formal economic transactions. Excluding these activities creates an epistemic gap — the true size of the economy is underestimated, especially in countries with significant illicit markets. However, some economists argue that if illegal activities are substantial, they should be included in the GDP calculation because they contribute to overall economic activity, though reconciling this with the problematic nature of illegal transactions presents methodological challenges.

Conversely, the activities of the police, law enforcement agencies, and judiciary are included in GDP calculations as government expenditures. For instance, police wages, procurement of law enforcement services, and legal processes contribute to the economy's total output. Their expenditures reflect legitimate, productive activities aimed at maintaining law and order. Therefore, law enforcement activities are considered a part of government services, thus being incorporated into the official GDP figures.

Conclusion

Calculating GDP accurately requires an understanding of the different approaches—final goods, value-added, and income methods—and their application to various sectors. While the formal economy's contributions are well accounted for, illicit activities remain excluded due to methodological and ethical considerations. However, the government's role in law enforcement and regulation significantly impacts the overall economic environment and is captured through public expenditure components of GDP.
