Balance of Payments Problem Set Balance of Payments Problem Set 1. Which of the balance of payments accounts do the following events affect? a. Boeing, a U.S.-based company, sells a newly built airplane to China. The sale of the new airplane to China represents an export of a good to China and so enters the current account. b. Chinese investors buy stock in Boeing from Americans. The sale of Boeing stock to Chinese investors is a sale of a U.S. asset and so enters the financial account. c. A Chinese company buys a used airplane from American Airlines and ships it to China. Even though the plane already exists, when it is shipped to China it is an export of a good from the United States. So the sale of the plane enters the current account. d. A Chinese investor who owns property in the United States buys a corporate jet, which he will keep in the United States so he can travel around America. Because the plane stays in the United States, the Chinese investor is buying a U.S. asset. So this is identical to the answer to part (b): the sale of the jet enters the financial account 2. In the economy of Scottopia in 2008, exports equaled $400 billion of goods and $300 billion of services, imports equaled $500 billion of goods and $350 billion of services, and the rest of the world purchased $250 billion of Scottopia’s assets. What was the merchandise trade balance for Scottopia? What was the balance of payments on the current account in Scottopia? What as the balance of payments on financial account? What was the value of Scottopia’s purchases of assets from the rest of the world? In 2005, the merchandise trade balance was -$100 billion ($400 billion - $500 billion). The balance of payments on current account was -$150 billion [($400 billion + $300 billion) - ($500 billion + $350 billion)]. Since the balance of payments on financial account plus the balance of payments on current account must sum to zero, the balance of payments on financial account must have been +$150 billion. If the rest of the world bought $250 billion of Scottopia’s assets, Scottopia must have bought $100 billion of assets from the rest of the world. 1. What does the production possibilities curve (PPC) show? The PPC is a graphic representation of the trade-offs in the production of two goods. 2. What does it mean for one country to have an absolute advantage over another in trade? Absolute advantage means that one country can produce more of a good than another country. 3. What does it mean for one country to have a comparative advantage over another in trade? Comparative advantage means that one country can produce a good at a lower opportunity cost than another country. It may be producing less in absolute terms but still has an advantage in terms of lower opportunity cost. 4. The U.S. and England have the following production possibility curves. Using the information on the graphs above: A. The opportunity cost of 1 unit of Fish in the U.S. is 1/2 chip per fish. B. The opportunity cost of 1 unit of Chips in the U.S. is 2 fish per chip. C. The opportunity cost of 1 unit of Fish in England is 1/4 chip per fish. D. The opportunity cost of 1 unit of Chips in England is 4 fish per chip. E. The U.S. has an absolute advantage in fish AND chips. F. England has an absolute advantage in nothing. G. The U.S. has a comparative advantage in chips (the U.S. gives up fewer fish per chip than England). H. England has a comparative advantage in fish (England gives up fewer chips per fish than the U.S.). 5. Liam and Miley have two tasks they need to complete: mow the lawn and prepare meals for the day. They agree that trade is in their best interest, which is where they need your help. Using the information in the table below determine who should be responsible for the lawn and who should be working in the kitchen. Mow Lawns Prepare Meals Liam 60 mins 120 mins Miley 120 mins 360 mins A. Who has an absolute advantage in mowing lawns? Liam (it takes him less time to mow a lawn) B. Who has an absolute advantage in preparing meals? Liam (it takes him less time to prepare a meal) C. What is Liam’s opportunity cost associated with mowing 1 lawn? 1/2 meal per lawn D. What is Miley’s opportunity cost associated with mowing 1 lawn? 1/3 meal per lawn E. What is Liam’s opportunity cost associated with preparing 1 meal? 2 lawns per meal F. What is Miley’s opportunity cost associated with preparing 1 meal? 3 lawns per meal G. Who has a comparative advantage in mowing lawns? Miley because she gives up fewer meals per lawn H. Who has a comparative advantage in preparing meals? Liam because he gives up fewer lawns per meal 6. The following figures represent the amount that can be produced with a fixed amount of factor inputs. Country Shirts TVs China 400 200 India 120 30 A. Which country has an absolute advantage in producing shirts? China B. Which country has an absolute advantage in producing TVs? China C. What is China’s opportunity cost for producing one shirt? 1/2 TVs per shirt D. What is India’s opportunity cost for producing one TV? 4 shirts per TV E. Identify which country has a comparative advantage in shirts? India has the comparative advantage because its opportunity cost (1/4 TV per shirt) is less than China’s (1/2 TVs per shirt). F. Which country has the comparative advantage in TV? China has the comparative advantage because its opportunity cost (2 TVs per shirt) is less than India’s (4 TVs per shirt). G. Explain why these countries can benefit from trade. Both are able to increase their consumption of TVs and shirts due to trade. .

  • Distributional Effect of International Trade and Comparative Advantage in Labor Markets∗
    Distributional Effect of International Trade and Comparative Advantage in Labor Markets∗ Rodrigo Adão MIT September 20, 2015 Abstract This paper investigates the distributional consequences of international trade shocks in the con- text of the Brazilian labor market. First, I document a new set of facts about how differential ex- posure to commodity price shocks across educational groups and regions leads to differential out- comes in terms of sectoral employment and wages. Second, I show that such facts are qualitatively consistent with a two-sector Roy model where worker heterogeneity regarding comparative and ab- solute advantage in sector-specific tasks determines the structure of employment and wages. Third, I establish that the schedules of comparative and absolute advantage are nonparametrically iden- tified from cross-regional variation in sectoral responses of employment and wages induced by sector demand shocks. Lastly, I build on this result to structurally estimate the model in the sample of Brazilian local labor markets. My structural estimates indicate that a 10% decrease in commod- ity prices causes counterfactual increases of 1.2% in the skill wage premium and of 5% in wage dispersion. ∗Author contact information: [email protected].

  • International Trade
    International Trade or centuries, people of the world have traded. From the ancient silk routes and spice trade to modern F shipping containers and satellite data transfers, nations have tied their economies to the rest of the world by complex flows of products and services. Free trade, which allows traders to interact without barriers imposed by government, can improve the living standards of people because it reduces prices and increases the variety of goods and services for consumers. It can also create new jobs and opportunities, and it encourages innovative uses of resources. However, even though free trade can benefit an economy as a whole, specific groups may be hurt. While certain sectors will experience job gains, others will face job losses. Still, societies throughout history have found that the benefits of international trade outweigh the costs. Why Trade? As consumers, all of us have an interest in trading they live, is because they believe they will be better with other countries. We often are unaware of trade’s off by trading. When we consider the alternative— influence on product prices and the quality and each of us producing everything for ourselves—trade availability of the goods we buy. But we all benefit simply makes more sense. from the greater abundance and variety of products and the lower prices that trading with others makes Trade is beneficial because it allows people to possible. Without trade, countries become isolated. specialize, or concentrate their work in the type of The quality of their goods and services lags behind production that they do best.

The present paper attempts to assess Iran’s Revealed Comparative Advantage (RCA) in industrial subsectors based on two-digit code of the International Standard Industrial Classification (ISIC) and effects of five top subsectors with the highest average of RCA on the total Iranian real industrial exports. RCAs for Iranian industrial subsectors (during 2001-2010) were calculated for 2001-2010 time period and seasonal data (2001- 2010) were collected to estimate the RCA Model. Auto Regressive Distributed Lags (ARDL) Method was employed to investigate the effects of these subsectors on the total Iranian real industrial exports. The econometric results show that the subsectors with highest RCA average have a positive and significant effect on the total Iranian real industrial exports. Key words: Revealed Comparative Advantage, Iranian industrial subsectors, Auto Regressive Distributed Lags (ARDL), Error Correction Model (ECM) 1. Introduction Today, foreign trade comprises a significant part of economic activities in many countries throughout the world. Besides, the significance and the role of foreign trade in the countries’ economic development have been rising since the early 19th century due to an unprecedented growth in the global economy.

  • Rural 3.0. a Framework for Rural Development (Policy Note)
    POLICY NOTE RURAL 3.0. A FRAMEWORK FOR RURAL DEVELOPMENT ABOUT This Policy Note shares the OECD’s Rural Policy 3.0—a framework to help national governments support rural economic development. The New Rural Paradigm, endorsed in 2006 by OECD member countries, proposed a conceptual framework that positioned rural policy as an investment strategy to promote competitiveness in rural territories. This approach represented a radical departure from the typical subsidy programmes of the past that were aimed at specific sectors. Rural Policy 3.0 is an extension and a refinement of this Paradigm. Where the New Rural Paradigm provided a conceptual framework, the Rural Policy 3.0 focuses on identifying more specific mechanisms for the implementation of effective rural policies and practices.

  • 5 Conclusions
    as an import barrier than an export subsidy. 5 Conclusions In this paper we assessed the effect of trade policies on external balances by adopting an approach that exploits differences in sectoral specialization and trade costs. To do so, we used (for the most part) data on bilateral trade flows to infer trade costs and sectoral comparative advantage for a globally representative set of countries over varying time periods. We also proposed an effective trade cost measure that weights trade costs by comparative advantage, thereby more accurately capturing costs that pertain to sectors in which countries may have a greater underlying potential to export and import. We found a modestly robust link between effective trade costs and current account outcomes. Thus, countries facing higher effective costs to export tend to have only somewhat lower CA balances, which implies that the overall contribution of trade costs to global imbalances has been small. These results are consistent with previous theoretical predictions suggesting limited effects of trade costs on current account balances. One limitation of this approach is that our estimates could be biased by the potential for causality to instead run from the CA to effective trade costs. Dekle, Eaton, and Kortum (2008) point out that movements in the current account can have general equilibrium effects on sectoral prices and wages, which in turn can have implications for comparative advantage. In the Eaton and Kortum (2002) framework that we adopt, such effects would be eliminated from our comparative advantage measure via the normalization by the country average of absolute advantage (`ala Hanson et al.
