Above the line In balance of payments accounting, this refers to those transactions that are included in calculating the balance of payments surplus or deficit. Transactions below the line, typically official reserve transactions and sometimes short term capital flows, are not included.
Absolute advantage The ability to produce a good at lower cost, in terms of real resources, than another country. In a Ricardian model, cost is in terms of labor only. Absolute advantage is neither necessary nor sufficient for a country to export a good. See comparative advantage.
Absolute advantage trade policy The idea, advocated by opponents of globalization, that a country should import only goods for which other countries have an absolute advantage, particularly goods that the importing country cannot (or cannot "reasonably") produce itself.
Absolute Purchasing Power Parity See purchasing power parity.
Absorption 1. Total demand for final goods and services by all residents (consumers, producers, and government) of a country (as opposed to total demand for that country's output). The term was introduced as part of the Absorption Approach.

Adjustable peg An exchange rate that is pegged, but for which it is understood that the par value will be changed occasionally. This system can be subject to extreme speculative attack and financial crisis, since speculators may easily anticipate these changes.
Adjusted for inflation Corrected for price changes to yield real equivalent. The adjustment divides nominal amount for each year by price index for that year -- e.g. the CPI or the implicit price deflator -- and multiplies by 100. Result is valued at the prices of the base year for the price index.
Adjustment assistance Government program to assist workers and/or firms whose industry has declined, either due to import competition (trade adjustment assistance) or from other causes. Such programs usually have two (conflicting) goals: to lessen hardship for those affected, and to help them change their behavior -- what, how, or where they produce.
Adjustment cost The cost -- temporary but sometimes severe -- incurred by a person or firm in moving from one equilibrium to another. Many of the costs associated with trade liberalization are adjustment costs and are not accounted for in the usual measures of gains from trade.
Adjustment mechanism The theoretical process by which a market changes in disequilibrium, moving toward equilibrium if the process is stable. See Walrasian and Marshallian adjustment.
Administered price A price for a good or service that is set and maintained by government, usually requiring accompanying restrictions on trade if the administered price differs from the world price.

Alchian-Allen Theorem The proposition, due to Alchian and Allen (1964), that when the same absolute cost (as for transportation) is added to the prices of a low-price, low-quality good and a high-price, high-quality good, the relative demand for the latter will increase, since its relative price falls. Summarized as "shipping the good apples out," the result has been confirmed in international trade by Hummels and Skiba (2004).
Allocation An assignment of economic resources to uses. Thus, in general equilibrium, an assignment of factors to industries producing goods and services, together with the assignment of resulting final goods and services to consumers, within a country or throughout the world economy.
Allocation puzzle The fact that capital flows across developing countries, not toward countries that invest and grow more as one would expect, but away from them. Identified and named by Gourinchas and Jeanne (2007).

Asymmetric shock An exogenous change in macroeconomic conditions affecting differently the different parts of a country, or different countries of a region. Often mentioned as a source of difficulty for countries sharing a common currency, such as the Euro Zone.
At par At equality. Two currencies are said to be "at par" if they are trading one-for-one. The significance is more psychological then economic, but the long decline of the Canadian dollar "below par" with the U.S. dollar, and the more recent variation of the euro between above and below par, also with the U.S. dollar, have been cause for concern.
At PPP Measured using PPP exchange rates rather than nominal exchange rates, and thus comparing in terms of real purchasing power.

Autarkic Associated with the situation of autarky.
Autarky The situation of not engaging in international trade; self-sufficiency. (Not to be confused with "autarchy," which in at least some dictionaries is a political term rather than an economic one, and means absolute rule or power.)
Autarky equilibrium In a model of an economy, the configuration of prices and quantities at which quantities supplied and demanded within the economy are equal, so that no trade would take place even if it were permitted.
Autarky price Price in autarky; that is, the price of something within a country when it is not traded by that country. Relative autarky prices turn out to be the most theoretically robust (but empirically elusive) measures of comparative advantage.

Depending on how the licensing is administered, automatic licensing can add to the bureaucratic and/or time cost of trade.
Automatic stabilizer An institutional feature of an economy that dampens its macroeconomic fluctuations, e.g., an income tax, which acts like a tax increase in a boom and a tax cut in a recession.
Automaticity The feature of the WTO dispute settlement mechanism whereby panel reports are adopted automatically unless blocked by a unanimous vote of the membership (but then are subject to review by the Appellate Body). Under the prior GATT, unanimity was required to adopt, rather than reject, panel reports.
Autonomous Refers to an economic variable, magnitude, or entity that is caused independently of other variables that it may in turn influence; exogenous.
Autonomous consumption That portion of consumption that is autonomous. For example, if the consumption function has the form C=C0+cY, where C0 and c are parameters and Y is income, then C0 may be called autonomous consumption. An increase in autonomous consumption then represents an upward shift in the consumption function.
Autonomous transaction In the balance of payments, a transaction that is not itself a result of actions taken officially to manage international payments; in contrast with accommodating transaction.
Availability theory A theory of the determinants of international trade, due to Kravis (1956), that says that countries import what they do not have available domestically and export what they do. The theory can be said to encompass explanations of trade that stress factor endowments, technological differences, and product differentiation.
AVE Ad valorem equivalent
Average cost Total cost divided by output.
Average product The average product of a factor in a firm or industry is its output divided by the amount of the factor employed.
Average propensity The fraction of total income spent on an activity, such as consumption or imports. See propensity.

Average propensity to import The fraction of total income spent on imports; thus the ratio of imports to GDP. Contrasts with marginal propensity to import.
Average tariff An average of a country's tariff rates. This can be calculated in several ways, of which none are ideal for representing how protective the country's tariffs are. Most common is the trade-weighted average tariff, which under-represents prohibitive tariffs, since they get zero weight.
Average tax rate The amount paid as tax as a fraction of the amount being taxed. In the case of an income tax, the total amount of tax as a fraction of total income. Contrasts with marginal tax rate.
