REVALUATION: The act of increasing the price (exchange rate) of one nation's currency in terms of other currencies. This is done by the government if it wants to raise the price of the country's exports and lower the price of foreign imports. This is an appropriate action if the country is running an undesired trade surplus with other countries. The procedure for revaluation is for the government to buy the nation's currency and/or sell foreign currencies through the foreign exchange market.

  • The natural tendency for the economy to expand and contract.
  • Business cycles, which are irregular, nonperiodic fluctuations in aggregate economic activity.
  • The Great Depression, the worst economic period in this century.
  • Expansionary good times that mean more production and rising living standards, but also inflation and inefficiency problems.
  • Contractionary bad times that mean unemployment, less production, lower profits, bankruptcies, and social problems, but also lower inflation and more efficiency resource allocation.

LEAKAGES LINE

A graphical representation of the relation between the level of aggregate production and one or more leakages. The three leakages (non-consumption uses of the income generated from aggregate production) are saving, taxes, and imports. The leakages line sequentially adds, or layers, each of these three uses of income depending on the number of sectors used in the analysis (two, three, or four). The slope of the leakages line depends on which if any of the uses of income are induced by aggregate production. The leakages line is combined with the injections line (containing investment expenditures, government purchases, and exports) in the Keynesian injections-leakages model.

[What's This?]

Today, you are likely to spend a great deal of time at an auction seeking to buy either storage boxes for your income tax returns or an AC adapter for your CD player. Be on the lookout for florescent light bulbs that hum folk songs from the sixties.
