This means that income earned by the residents of other countries for their involvement in production in Metrica is (Click to select) than income earned by residents of Metrica for their involvement in production in the rest of the world. Answer Dear Professor, I have analyzed the table of Metrica's National Accounts for 2022 and have carefully considered the economic significance of each component. Based on my understanding of national income accounts and GDP calculations, I am able to provide a comprehensive response to the given question. a. The income-based estimate of Metrica's GDP is $980 billion. This is calculated by adding the income earned from corporate income, wages and salaries, net international income, proprietors' incomes and rents, and subtracting the indirect taxes and depreciation. Therefore, it is calculated as follows: $99 + $542 + $4 + $54 – $73 – $75 = $980 billion. b. The expenditure-based estimate of Metrica's GDP is $1,025 billion. This is calculated by adding the government purchases, personal consumption, gross investment, and exports and subtracting the imports. Therefore, it is calculated as follows: $178 + $478 + $152 + $73 + $73 – $26 = $1,025 billion. c. The value of the statistical discrepancy, which is added to the lower estimate and subtracted from the higher estimate to find a single GDP value, is $45 billion. This value is calculated as the difference between the two GDP estimates: $1,025 billion - $980 billion = $45 billion. d. Based on the above calculations, the GDP of Metrica is $1,025 billion. e. Metrica's capital stock is increased by $127 billion ($152 billion - $26 billion) due to the positive net exports of $73 billion in the national income accounts. This is because net exports contribute to the country's capital stock, as the revenue from exports is used to purchase assets or invest in the domestic economy. f. Metrica's Gross National Income (GNI) is $984 billion. This is calculated by adding the national GDP ($1,025 billion) and the net international income to the rest of the world ($4 billion) and subtracting the income earned by non-residents in Metrica ($45 billion). Therefore, it is calculated as follows: $1,025 billion + $4 billion - $45 billion = $984 billion. The income earned by the residents of other countries for their involvement in production in Metrica is higher than the income earned by residents of Metrica for their involvement in production in the rest of the world. This is because Metrica has a positive net international income, indicating that it earns more from its foreign investments and assets than it pays out to non-resident workers or investors. In conclusion, based on the given data and the principles of national income accounts, the GDP of Metrica for 2022 is $1,025 billion and its GNI is $984 billion. The country's positive net exports and net international income contribute to its capital stock and overall economic growth. These calculations and conclusions are supported by various academic sources such as Principles of Macroeconomics by N. Gregory Mankiw, National Income and Product Accounts Handbook by the Bureau of Economic Analysis, and the World Bank's System of National Accounts. I hope this answer provides a thorough and accurate analysis of Metrica's National Accounts for 2022. Thank you for the opportunity to demonstrate my understanding of national income accounting and GDP calculations. Sincerely, [Your name] Question 2 Hudson's Bay Closing Mall Stores As more people choose online shopping, the Bay has been closing mall stores. Source: National Post, September 13, 2019 Question content area bottom left Part 1 Use the information in the news clip to draw the following graphs. 1. Draw and label a PPF for mall retailing and online retailing before the Internet is available. 2. Draw and label a PPF for mall retailing and online retailing after the Internet is available. Part 2 1. Draw and label a curve to show the marginal benefit of retailing. 2. Draw and label a curve to show the marginal cost of mall retailing. 3. Draw and label a curve to show the marginal cost of online retailing before the Internet was available. 4. Draw and label a curve to show the marginal cost of online retailing after the Internet became available. Answer Hudson's Bay, a popular Canadian department store, has been facing challenges in the retail industry as more and more consumers shift towards online shopping. This trend has prompted the closure of many of its mall stores across the country. To understand the impact of this trend, we can use the concept of PPF (Production Possibility Frontier) and marginal analysis. Firstly, before the Internet was available, the PPF for mall retailing and online retailing would show a trade-off between the two types of retailing. Since the Internet was not accessible, consumers had limited options for retail shopping and therefore, mall retailing was the dominant form of retailing. This would result in a PPF showing a larger output of mall retailing compared to online retailing. Secondly, after the Internet became available, the PPF would shift outwards, representing an increase in production possibilities for both mall retailing and online retailing. With the convenience and ease of online shopping, consumers now have a wider range of options, leading to a decrease in mall retailing and an increase in online retailing. This would result in a PPF where online retailing is a larger proportion of the output compared to mall retailing. To further analyze this trend, we can use marginal analysis. Marginal benefit refers to the additional satisfaction or benefit a consumer receives from consuming one more unit of a good. For retailing, this would translate to the additional purchasing power of consumers as they shift towards online shopping. Therefore, the marginal benefit curve for retailing would shift upwards as the availability of online shopping increases. On the other hand, the marginal cost of mall retailing would increase as the demand for mall stores decreases due to the availability of online shopping. This would result in a rightward shift of the marginal cost curve for mall retailing. Similarly, the marginal cost of online retailing before the Internet was available would be lower compared to after, as online shopping platforms were not as sophisticated or easily accessible in the past. This would result in a leftward shift of the marginal cost curve for online retailing. Question 3 The table below shows the quantity of wood demanded and supplied in Japan at different prices. Price (in $) 280 325 364 Demand 32 27.5 23.6 422.5 Supply 17.75 8 9.5 10.8 12.75 Suppose Japan currently imposes a 30 percent tariff on imported wood and there are two foreign suppliers of wood: Russia and Canada. The price of Russian wood is $280, the price of Canadian wood is $325. As a result of growing political pressure to lower trade barriers, the Japanese government is considering to sign a free-trade agreement (FTA) with Canada. What will be the price of wood in Japan in the absence of the FTA? What will be the price of wood under the FTA with Canada? Answer Based on the given data, the price of wood in Japan in the absence of the FTA would be $280. This is because Japan currently imposes a 30 percent tariff on imported wood, which raises the price of both Russian and Canadian wood to $364 and $422.5 respectively. This means that the domestic supply of wood, which is 17.75 at this price, would be able to meet the domestic demand of 23.6 units, resulting in a surplus of 5.85 units. Under the FTA with Canada, the price of wood in Japan would decrease to $325. This is because the FTA would eliminate the 30 percent tariff on Canadian wood, making it more competitive in the Japanese market. This would shift the supply curve to the right, resulting in a higher quantity of wood supplied at a lower price. In this case, the domestic supply of 23.6 units would be able to meet the domestic demand of 27.5 units, resulting in a smaller surplus of 3.9 units. Question 4 The money price of a textbook is $90 and the money price of the Wii game Super Mario Galaxy is $45. What is the opportunity cost of a textbook in terms of the Wii game? What is the relative price of the Wii game in terms of textbooks? Question content area bottom The relative price of a Wii game in terms of textbooks is enter your response here textbook. >>> Answer to 1 decimal place. Answer The opportunity cost of a textbook in terms of the Wii game Super Mario Galaxy is $45. This means that if a student chooses to spend $90 on a textbook, they are giving up the opportunity to spend that money on Super Mario Galaxy. To calculate the opportunity cost, we must determine the value of the alternative option, in this case, the Wii game, and subtract it from the value of the first option, the textbook. In this scenario, the value of the Wii game is $45, so the opportunity cost of the textbook is $90 - $45 = $45. The relative price of the Wii game in terms of textbooks can be calculated by dividing the price of the Wii game by the price of the textbook. In this case, it would be $45/$90 = 0.5. This means that the Wii game is priced at half the cost of the textbook. In terms of usefulness, the concept of opportunity cost is an important one in economics as it demonstrates the trade-offs that individuals must make when faced with scarcity. The relative price calculation is also useful in analyzing the relationship between prices of different goods in the marketplace. Question 5 Think of examples of goods whose relative price has risen or fallen by a large amount. In 2015, the price of a litre of gas was 99.1 cents. In 2021, the price of a litre of gas was 140.0 cents. In 2015, the price of a dozen eggs was $3.26. In 2021, the price of a dozen eggs was $3.64. Question content area bottom Part 1 Between 2015 and 2021, the relative price of a litre of gas with respect to a dozen eggs _______ and the relative price of a dozen eggs with respect to a litre of gas _______. A. fell; fell B. rose; fell C. rose; rose D. fell; rose Answer According to the given data, we can observe that the prices of both gasoline and eggs have increased between the years 2015 and 2021. In 2015, the price of a litre of gas was 99.1 cents, while in 2021 it increased to 140.0 cents. Similarly, the price of a dozen eggs was $3.26 in 2015 and increased to $3.64 in 2021. This shows that the relative prices of both goods have risen over this time period. To calculate the relative prices, we can use the formula (P1/P2) x 100, where P1 represents the initial price and P2 represents the final price. Using this formula, we can see that the relative price of a litre of gas with respect to a dozen eggs has increased from 3042.33 in 2015 to 3835.21 in 2021. Similarly, the relative price of a dozen eggs with respect to a litre of gas has increased from 0.033 to 0.026 over the same time period. This significant increase in relative prices can be attributed to several factors such as changes in demand and supply, changes in the cost of production, and changes in government policies. In the case of gasoline, the increase in relative price can be linked to the increase in demand due to a rise in global oil prices, along with an increase in production costs. On the other hand, the increase in the relative price of eggs can be attributed to an increase in demand for protein-based diets, as well as changes in government regulations for egg production.
