45. Summary

46. Comparative advantage is a principle that allows nations to gain from trade. Comparative advantage means that each nation specializes in a product for which its opportunity cost is lower in terms of the production of another product and then nations trade.

47. When nations follow the principle of comparative advantage, they gain
When nations follow the principle of comparative advantage, they gain. The reason is that world output increases and each nation ends up with a higher standard of living by consuming more goods and services than possible without specialization and trade.

49. Free trade benefits a nation as a whole, but individuals may lose jobs and incomes from the competition from foreign goods and services.

50. Protectionism is a government’s use of embargoes, tariffs, quotas, and other methods t impose barriers intended to both reduce imports and protect particular domestic industries.

51. Embargoes prohibit the import of export of particular goods
Embargoes prohibit the import of export of particular goods. Tariffs discourage imports by making them more expensive. Quotas limit the quantity of imports or exports of certain goods. These trade barriers often result primarily from domestic groups that exert political pressure to gain from these barriers.

52. The balance of payments is a summary bookkeeping record of all the international transactions a country makes during a year. It is divided into different accounts, including the current account, the capital account and the statistical discrepancy.

53. The current account summarizes all transactions in currently produced goods and services. The overall balance of payments is always zero after an adjustment for the statistical discrepancy.

54. The balance of trade measures only goods (not services) that a nation exports and imports. A balance of trade can be in deficit or in surplus. The balance of trade is the most widely reported and largest part of the current account. Since 1975, the U.S. has experienced balance of trade deficits.

56. An exchange rate is the price of one nation’s currency in terms of another nation’s currency. Foreigners who wish to purchase U.S. goods, services, and financial assets demand dollars. The supply of dollars reflects the desire of U.S. citizens to purchase foreign goods, services and financial assets.

57. The intersection of the supply and demand curves for dollars determines the number of units of a foreign currency per dollar.

59. Shifts in supply and demand for foreign exchange result from changes in such factors as tastes, relative price levels, relative real interest rates, and relative income levels.

60. Depreciation of currency occurs when one currency becomes worth fewer units of another currency. If a currency depreciates, it becomes weaker. Depreciation of a nation’s currency increases its exports and decreases its imports.

61. Appreciation of currency occurs when one currency becomes worth more units of another currency. If a currency appreciates, it becomes stronger. Appreciation of a nation’s currency decreases its exports and increases its imports.
