Document Summary
One of the ten principles of economics from chapter 1: trade can make everyone better off. This chapter introduces basic concepts of international macroeconomics: the trade balance (trade deficits, surpluses, international flows of assets, exchange rates. A closed economy does not interact with other economies in the world. An open economy interacts freely with other economies around the world: it buys and sells goods and services in world product markets, it buys and sells capital assets in world financial markets. Net exports (nx), aka the trade balance = value of exports value of imports. Net exports: the value of a nation"s exports minus the value of its imports; also called the trade balance. Trade surplus: an excess of exports over imports. If net exports are positive, exports are greater than imports, indicating that country sells more goods and services abroad than it buys from other countries. Trade deficit: an excess of imports over exports.
