(cont.)•International trade as a fraction of the national economy has tripled for the US in the past 40 years.•Compared to the US, other countries are even more tied to international trade.Copyright © 2006 Pearson Addison-Wesley.

When a buyer and a seller engage in a voluntary transaction, both receive something that they want and both can be made better off.•Norwegian consumers could buy oranges through international trade that they otherwise would have a difficult time producing.•The producer of the oranges receives income that it can use to buy the things that it desires.Copyright © 2006 Pearson Addison-Wesley.

How could a country that is the most (least) efficient producer of everything gain from trade?With a finite amount of resources, countries can use those resources to produce what they are most productive at (compared to their other production choices), then trade those products for goods and services that they want to consume.Countries can specialize in production, while consuming many goods and services through trade.Copyright © 2006 Pearson Addison-Wesley.

Trade is predicted to benefit a country by making it more efficient when it exports goods which use abundant resources and imports goods which use scarce resources.4. When countries specialize, they may also be more efficient due to large scale production.5. Countries may also gain by trading current resources for future resources (lending and borrowing).Copyright © 2006 Pearson Addison-Wesley.

All rights reserved.1-12The Effects of Government Policies on Trade•Policy makers affect the amount of trade through tariffs: a tax on imports or exports, quotas: a quantity restriction on imports or exports,export subsidies: a payment to producers that export,or through other regulations (e.g., product specifications) that exclude foreign products from the market, but still allow domestic products.•What are the costs and benefits of these policies?Copyright © 2006 Pearson Addison-Wesley. All rights reserved.1-13The Effects of Government Policies on Trade (cont.)•Economists design models that try to measure the effects of different trade policies.•If a government must restrict trade, which policy should it use?•If a government must restrict trade, how much should it restrict trade?•If a government restricts trade, what are the costs if foreign governments respond likewise?Copyright © 2006 Pearson Addison-Wesley. All rights reserved.1-14International Finance Topics•Governments measure the value of exports and imports, as well as the value of international financial capital that flows into and out of their countries.•Related to these two measures is the measure of official settlements balance, or the balance of payments: the balance of funds that central banks use for official international payments.•All three values are measured in the government’s national income accounts.Copyright © 2006 Pearson Addison-Wesley. All rights reserved.1-15International Finance Topics (cont.)•Besides international financial capital flows and the official settlements balance, exchange rates are also an important financial issue for most governments.Exchange rates measure how much domestic currency can be exchanged for foreign currency.They also affect how much goods that are denominated in foreign currency (imports) cost.And they affect how much goods denominated in domestic currency (exports) cost in foreign markets.Copyright © 2006 Pearson Addison-Wesley.
