|Nash||Used as an adjective applied to a strategy in a game, this means that it is part of a Nash equilibrium.|
|Nash equilibrium||An equilibrium in a game in which each player's action or strategy is optimal given those of other players.

Thus it is the total of a national government's outstanding government bonds.|
|National defense argument for protection||The argument to restrict imports so as to sustain a domestic industry that will be needed in case of trade disruption due to war.

|Natural monopoly||An industry with such increasing returns to scale that an economy can only support, at close to minimum cost, a single firm. To avoid the economic inefficiency of monopoly pricing, such industries are often regulated or owned by government. Internationally, this may prompt interference with trade.|
|Natural person||This term appears in the GATS where it deals with the international movement of employees of firms that are providing services in another country. Persons are called "natural" to distinguish them from "juridical persons," such as partnerships or corporations, which are given certain rights of persons under the law.|

|Neighborhood production structure||A structure of technology for a general equilibrium model due to Jones and Kierzkowski (1986). With an arbitrary but equal number of goods and factors, each factor produces two (different) goods and each good uses two (different) factors, yielding more unambiguous results than usual in high-dimension trade models without specific factors.|
|Neoclassical||A set of assumptions made by mainstream economists starting in the late 19th century, including firm profit maximization, consumer utility maximization, and market clearing, with corresponding implications for factor prices and income distribution. Contrasts with classical, Keynesian, and Marxist.|

2. A more extreme version of the above, viewed negatively, as emphasizing the freedom of large corporations to make profits and limiting even further the role of government in redistribution and the provision of social services.
|Neotechnology model||Any model that explains trade using evolving differences in technologies across countries over time. Two models have been most widely cited: the technology gap model and the product cycle model. The term "neotechnology" is said by Borkakoti (1975) to have been first applied to these by Hufbauer (1970).|
|NES||Not Elsewhere Specified. This abbreviation, "nes," appears frequently in classifications, of goods and of industries for example, to encompass all other items in a category that have not been included explicitly.|

2. Of a country, national income minus capital consumption allowance.
|Net international reserves||International reserves minus reserves that have been borrowed from the IMF and other governments.|
|Net investment||Gross investment minus depreciation.|
|Net national expenditure||This does not seem to be a standard term, although logic suggests that it is gross national expenditure minus depreciation, thus using net investment rather than gross investment in measuring expenditure.|
|Net national product||Gross national product minus depreciation. This is the most complete measure of productive activity by a country's nationals, though its accuracy suffers from the difficulty of measuring depreciation.|
|Net output||The output of a product that is available for final users, after deducting amounts of it used up as an intermediate input in producing itself and other products. Contrasts with gross output.|
|Net present value||Same as present value, being sure to include (negative) payments as well as (positive) receipts.|

2. Said of economic growth if it expands actual or potential output of all goods at the same rate, not being biased in favor of one over another. In the H-O Model neutral growth will occur if all factor endowments grow at the same rate or if there is Hicks Neutral technological progress at the same rate in all industries.
3. Said of a trade regime if the structure of protection favors neither exportables nor importables. See bias.

|Nominal GDP||GDP as actually measured, thus in current dollars. Contrasts with real GDP.|

|Nominal return||The earnings on an asset or other investment, comparable to a nominal interest rate, thus not adjusted for inflation.|
|Nominal rigidity||The inability of a nominal variable, such as a price or a wage expressed in money terms (as opposed to real), to change quickly so as to achieve equilibrium. Nominal rigidities tend to be needed in Keynesian macroeconomic models.|
|Nominal tariff||The nominal protection provided by a tariff; that is, the tariff itself. Contrasts with effective tariff.|
|Nominal wage||The wage of labor in units of currency, not adjusted for inflation, and thus not in terms of the goods that it will buy. Contrasts with real wage.|
|Non-actionable subsidy||A subsidy that is not subject to countervailing duties under the rules of the WTO. These include non-specific subsidies, subsidies for industrial research, regional aids, and some environmental subsidies.|

|Non-economic objectives argument for protection||The view that a restriction on imports may serve a purpose outside of conventional economic models. Unless that purpose is itself the restriction of trade, this is a second best argument, since changes in output, consumption, etc., can be achieved at lower economic cost in other ways.|
|Non-governmental organization||A not-for-profit organization that pursues an issue or issues of interest to its members by lobbying, persuasion, and/or direct action. In the arena of international economics, NGOs play an increasing role defending human rights and the environment, and fighting poverty.|

|Non-reciprocal||Not reciprocal. Thus a trade agreement is non-reciprocal if one party makes concessions while the other does not.|
|Non-specific subsidy||A subsidy that is available to more than a single specific industry and is therefore non-actionable under WTO rules.|
|Nonbinding||Refers to a restriction that currently has no effect because the behavior that it would prevent would not happen even without the restriction. For example, if a quota limits imports to no more than 1,000, but actual imports are only 900, then the quota is nonbinding.|
|Nonconvexity||The property of an economic model or system that the sets representing technology, preferences, or constraints are not mathematically convex. Because convexity is needed for proof that competitive equilibrium is efficient and well-behaved, nonconvexities may imply market failures.|

In trade this often refers to levying the same tariffs against the imports from all other countries and the absence of nontariff barriers that put some imports at a disadvantage compared to others.|

|Nonproduction worker||A worker not directly engaged in production. In empirical studies of skilled and unskilled labor, data on nonproduction workers are often taken to represent skilled labor, though the correspondence is far from exact.|
|Nonprohibitive tariff||A tariff that is not prohibitive.|
|Nonsterilization||Refers to exchange market intervention that is done without sterilizing its effects on the domestic money supply and that therefore changes the money supply.|
|Nontariff barrier||Any policy that interferes with exports or imports other than a simple tariff, prominently including quotas and VERs.|
|Nontariff measure||Any policy or official practice that alters the conditions of international trade, including those that act to increase trade as well as those that restrict it. The term is therefore broader than nontariff barrier, although the two are usually used interchangeably.|
1. Not capable of being traded among countries.
2. A good or service that is nontradable, with nontradables referring to an aggregate of such goods and services.
|Nontradable good||A good that, by its nature, is nontradable.|

|Normal good||A good the demand for which rises with income if relative prices do not change. Contrasts with inferior good.|
|Normal profit||The level of profit that neither attracts entry into, nor causes exit from, an industry . It typically means that firms are earning just enough to provide a competitive return on their capital.|
|Normal trade relations||The term in the United States for designating a country as qualifying for the MFN tariffs that have been negotiated in the GATT. [Origin]|
|Normal value||Price charged for a product on the domestic market of the producer. Used to compare with export price in determining dumping.|

|NRP||Nominal rate of protection|
|NTE||National Trade Estimate|
|NTR||Normal trade relations|
|Numeraire||The unit in which prices are measured. This may be a currency, but in real models, such as most trade models, the numeraire is usually one of the goods, whose price is then set at one. The numeraire can also be defined implicitly by, for example, the requirement that prices sum to some constant.|
