By the year 2020, Japan is expected to receive more in income from overseas investments than she pays in income to foreigners who own assets in Japan in an amount equal to 2.0 percent of Japan’s GDP. Also, because of a drop in saving associated with an aging population, Japan’s capital outflow in 2020 is expected to exceed capital inflow but only by 0.5 percent of her GDP. Given this forecast, we can expect the Japan’s balance of trade (exports minus imports) in 2020 to be _____% of GDP.
Shown below are selected macroeconomic variables for a given country. Use the values given for the first four variables to determine the missing values for the last four variables. Gross domestic product (GDP) = 10,000; Gross national income (GNI) = 8,400; Current account balance (CA) = -500; Domestic investment (I) = 2,400; Balance of trade (X-M) = ?; National saving (S) = ?; Gross national expenditure (GNE) = ?; Net capital outflow (KO-KI) = 7. Airbus (a European consortium) operates a plant in Alabama. To make a commercial aircraft, the plant purchases engines from a factory in Germany and instruments and assorted parts from aerospace companies in California. The Alabama plant manufactures the frame and assembles the aircraft. A typical Airbus plane which costs $30 million contains $10 million worth of engines, $8 million worth of instruments and other parts. The value added by the Alabama plant makes up the remaining $12 million. How would U.S. GDP and its components be affected by the production of an Airbus plane in Alabama?
The following equations describe the macro economies of two countries. Assume that GDP and GNI are equal. They are denoted Y. Use the information to answer the questions below. Note: The interest rates r and r are in percent. Avoid simple algebraic mistakes. Home country: Y = 5000; C = 775 + 0.75(Y–T) – 150r; I = 1000 – 50r; G = T = 1000. Foreign country: Y = 3750; C = 700 + 0.75(Y–T) – 100r; I = 500 – 50r; G = T = 750.

1. Suppose that individual demand for a product is given by Q = P. Marginal revenue is MR = 0.4Q, and marginal cost is constant at $20. There are no fixed costs. a. The firm is considering a quantity discount. The first 400 units can be purchased at a price of $120, and further units at $80. How many units will the consumer buy in total? b. Show that this second-degree price discrimination scheme is more profitable than a single monopoly price.
2. A monopolist sells in two geographically divided markets, the East and the West. Marginal cost is $50 in both markets. Demand and marginal revenue are: Qe = 1200 – 2Pe, MRe = 600 – Qe; Qw = 800 – Pw, MRw = 800 – 2Qw. a. Find the profit-maximizing price and quantity in each market. b. Which market has more elastic demand? How can you tell? c. Under what conditions is price discrimination effective and why?
3. Consider a market with a monopolist and a firm considering entry. The new firm knows that if the monopolist fights (sets a low price), the new firm will lose money. If the monopolist accommodates (sets a high price), the new firm profits. The payoff matrix is:

Paper For Above instruction
The given set of questions covers multiple aspects of macroeconomic and microeconomic theory, focusing on national income accounting, balance of payments, open economy models, firm pricing strategies, and personal economic decision-making. This robust examination provides insight into how economies operate internally and externally, as well as how firms and individuals make decisions that influence aggregate economic indicators. This essay synthesizes and responds to each question with detailed explanations, calculations, and economic reasoning, supported by relevant literature and economic principles.
Introduction
Understanding national income accounting is fundamental in macroeconomics, providing a basis for analyzing an economy’s overall health. The questions about the recording of imports, the components of investment, and the implications of capital flows highlight the importance of accurately measuring economic activity and the interconnectedness of global markets. Additionally, the macroeconomic variable analysis involving savings, investment, and external balances reflects the complexities faced by open economies.
Microeconomic concerns, such as monopolistic pricing strategies and price discrimination, underscore behavioral models of firms in different market structures. The analysis of profit maximization strategies and threat credibility offers critical insights into strategic interactions in markets. Furthermore, personal finance questions, like the economic versus accounting profit, reveal the importance of opportunity costs and the broader implications of economic decisions at the individual level.
National Income and the Impact of Imports
In the scenario where the Smith family purchases a Swedish-made Volvo in the U.S., the transaction affects several macroeconomic variables. When a U.S. resident purchases an imported good, it is recorded as an increase in imports (M), which is subtracted from GDP in the expenditure approach. Therefore, even though consumption (C) rises, GDP remains unaffected because the imported vehicle does not constitute domestic production, leading to an increase in imports and no change in gross domestic product (GDP). This aligns with standard national income accounting conventions (Mankiw, 2020).
Components of Gross Domestic Investment
Gross domestic investment includes expenditures on new capital assets within the country. Tractors made and sold within the U.S., regardless of whether sold domestically or abroad, are included because they contribute to domestic capital formation. Conversely, tractors produced domestically but sold abroad do not count as investment in the U.S., emphasizing that investment measures domestic production regardless of the market where the final sale occurs. Similarly, foreign-produced tractors sold in the U.S. contribute to imports but are not part of domestic investment.
Capital Outflows and External Wealth
Capital outflows occur when residents or firms invest abroad, such as building facilities or purchasing foreign bonds, reducing internal wealth and increasing external assets owned abroad. Conversely, inflows increase domestic assets. If capital inflow exceeds outflows, the external wealth position declines because the country is effectively transferring wealth overseas, which diminishes net external wealth (Krugman, 2018). The cases of Intel building in Vietnam or Boeing selling aircraft to China reflect foreign direct investment and exports, respectively, while foreign bond purchases by individuals are financial outflows.
Balance of Payments and External Wealth
When capital inflows surpass outflows, the country’s net external wealth declines, implying a current account deficit (CA
Japan’s Income and Saving in 2020
Given Japan’s expected income and investment income balance, along with its savings behavior, the trade balance can be inferred. Since the income from investments exceeds payments, Japan experiences a net income inflow of 2.0% of GDP. The difference between savings and investments, coupled with the net income, suggests a small trade deficit of about 0.5% of GDP, aligning with the forecasted capital outflow exceeding inflow by 0.5%. Consequently, Japan’s trade (X–M) would be approximately –0.5% of GDP, indicating a slight trade deficit.
Macroeconomic Variable Analysis
Using the data provided about GDP, GNI, and investment, we can calculate missing variables like national savings, net exports, and GNE. The savings function in each country depends on disposable income (Y–T) and interest rates, affecting overall savings behavior. Solving these equilibrium conditions demonstrates how the global interest rate balances savings and investment across nations, critical for understanding open economy macroeconomics (Frieden & Broz, 2019).
Impact of Airbus Production on U.S. GDP
The production of Airbus aircraft in Alabama contributes to U.S. GDP through value added by the Alabama plant. The purchase of parts from Germany and California constitutes intermediate consumption, which is subtracted to avoid double counting. The value added by the Alabama plant ($12 million) and the costs of imported components are recognized in GDP, with the total contribution being the sum of domestic value added and imported inputs, influencing the components of gross domestic product accordingly (Mankiw, 2020).
Open Economy Equilibrium and Net Capital Flows
Deriving the saving functions involves substituting consumption functions into the savings formula and analyzing how savings respond to interest rate changes. The equilibrium interest rate is determined where global savings equal investment, considering both domestic and foreign variables. The net capital outflow is then calculated as the difference between savings and investment, and the divergence between GDP and GNE reflects differences between income, expenditures, and consumption patterns (Obstfeld & Rogoff, 2020).
Microeconomic Pricing Strategies and Market Power
Price discrimination strategies, including second-degree and third-degree discrimination, are profitable when firms can segment markets and price according to elasticity of demand. The scheme with quantity discounts allows firms to extract consumer surplus and increase profits, especially when demand elasticity varies across segments (Varian, 2014). The credibility of threats in price-setting depends on the strategic environment and the ability to commit to future actions, emphasizing game theory principles.
Conclusion
In sum, the questions span a comprehensive set of economic concepts from national accounts to microeconomic strategies, illustrating the interconnectedness of economic policy, firm behavior, and individual decisions. Understanding these fundamentals enables policymakers and firms to navigate complex economic landscapes, shaping strategies that influence macroeconomic stability and growth.
