|Money laundering||The conversion of large amounts of money the source of which one wants to hide (e.g., from drug trafficking) into a form that appears to be legitimate. The process often involves multiple international transactions across currencies and financial institutions in order to obscure the source.|
|Money market||The money market, in macroeconomics and international finance, is the equilibration of demand for a country's domestic money to its money supply. These are amounts that people in the country do, and want to, hold at a point in time (a stock). Not to be confused with the exchange market, which equates flows.|
|Money multiplier||When a central bank uses open market operations to change the monetary base, the money multiplier is the ratio of the resulting change in the money supply to the change in the base. If banks and others keep the base at a fraction, ρ, of the money supply (e.g., if only banks hold currency, with a reserve ratio, ρ), the money multiplier is 1/ρ.|
|Money neutrality||Monetary neutrality|
|Money overhang||A money supply that is larger than what people want to hold at prevailing prices, perhaps because of shortages or rationing of goods in the past. This was said to be a major cause of inflation in Russia after the fall of the Soviet Union, which left an excess of money in circulation.|
|Money price||The nominal price; thus the price as it would actually be observed, in current dollars. Contrasts with the real price, which is adjusted for inflation.|
|Money supply||There are several formal definitions, such as M1 and M2, but all include the quantity of currency in circulation plus the amount of demand deposits. The money supply, together with the amount of real economic activity in a country, is an important determinant of its price level and its exchange rate.|
|Monopolistic||Having some power to set price.|
|Monopolistic competition||A market structure in which there are many sellers each producing a differentiated product. Each can set its own price and quantity, but is too small for that to matter for prices and quantities of other producers in the industry.|
|Monopoly||A market structure in which there is a single seller.|
|Monopoly argument||The monopoly argument for a tariff is the same as the optimal tariff argument. It gets its name from the fact that a country using a tariff to improve its terms of trade is acting much like a monopoly firm, restricting its sales to get a better price. A more accurate analogy would be to monopsony.|
|Monopoly price||The profit-maximizing price charged by a monopolist. Because a monopoly faces a demand elasticity, η>0, that is finite, this price exceeds marginal cost. The optimal markup over marginal cost is (P−MC)/P=1/η.|
|Monopsony||A market structure in which there is a single buyer. Term introduced in Robinson (1932).|
|Monotonic||Changing in one direction only; thus either strictly rising or strictly falling, but not reversing direction.|

A pervasive problem in the insurance industry, it also arises internationally when international financial institutions assist countries in financial trouble.|
|Moral rights||In terms of IP, these are the rights of an author or other creative person over how their creation is used, modified, etc., after the economic rights have been transferred to somebody else by copyright. Moral rights are not uniform across IP jurisdictions and are not regulated by the WTO's TRIPs Agreement.|
|Mortgage||A loan the collateral for which is a house or other real estate. Became relevant for international economics in 2008 when mortgage-backed securities, which had been traded internationally, contributed to the global financial crisis when borrowers defaulted after the bursting of the housing bubble.|
|Mortgage-backed security||A financial instrument that packages the ownership of shares in a large number of mortgages.|
|Most Favored Nation||The principle, fundamental to the GATT, of treating imports from a country on the same basis as that given to the most favored other nation. That is, and with some exceptions, every country gets the lowest tariff that any country gets, and reductions in tariffs to one country are provided also to others. [Origin]|
|Mothballing||The preservation of an idle production facility, keeping the machinery in working order and supplies available. This may be preferable -- if operating costs are high and the aim is to have it available in time of war -- to having it produce under a subsidy or import protection. See national defense argument.|
|Movement of natural persons||Mode 4 of four modes of supply under the GATS, this involving the temporary movement across national borders of natural persons employed by or associated with a firm in order to participate in the firm's business. Also called temporary producer movement.|

|MTO||Multilateral Trade Organization.|
|Multi-cone equilibrium||A free-trade H-O equilibriumin which all goods cannot be produced in one country; instead there are multiple diversification cones. This, or two cone equilibrium, arises if country factor endowments differ sufficiently relative to industry factor intensities. Contrasts with one cone equilibrium.|
|Multi-level governance||A theoretical perspective on the organization of modern states that acknowledges flexible structures of overlapping jurisdictions, both above and below the national government as well as in a lateral relationship to it.|
|Multi-region input-output table||An input-output table covering multiple countries and regions, such as Eora and the World Input-Output Database.|

|Multifactor model||A model with more than two factors. In the context of trade theory this is likely to mean a Heckscher-Ohlin Model with more than two factors.|
|Multifiber Arrangement||An agreement (OMA) among developed country importers and developing country exporters of textiles and apparel to regulate and restrict the quantities traded. It was negotiated in 1973 under GATT auspices as a temporary exception to the rules that would otherwise apply, and was superseded in 1995 by the ATC.|
|Multifunctionality||Refers to the purposes that an industry may serve in addition to producing its output. Most often applied to agriculture by countries that wish to subsidize it, arguing that subsidies are needed to serve these other purposes, such as rural viability, land conservation, cultural heritage, etc.|
|Multigood model||A model with more than two goods.|
|Multilateral||Among a large number of countries, usually including all countries that are members of a large international organization, such as the WTO. Contrasts with bilateral and plurilateral.|
|Multilateral agreement||An agreement among a large number of countries.|
|Multilateral Agreement on Investment||A proposed agreement to liberalize rules on FDI, negotiated in the OECD but never completed or adopted because of adverse public reaction. Preliminary text of the agreement was leaked to the Internet in April 1997, where many groups opposed it. Negotiations discontinued in November 1998.|
|Multilateral aid||Aid provided by a group of countries, or by an institution representing a group of countries such as the World Bank, to one or more recipient countries. Contrasts with unilateral aid.|
|Multilateral Debt Relief Initiative||An initiative proposed in 2005 by the G8 for debt relief by the IMF, IDA, and AfDF to be extended beyond that provided in the HIPC Initiative.|
|Multilateral Investment Guarantee Agency||One of the five institutions that comprise the World Bank Group, MIGA helps encourage foreign investment in developing countries.|
|Multilateral resistance||A term introduced into the gravity equation by Anderson and van Wincoop (2003) to account for overall distance and other trade impediments to a country's total trade. It must be considered, relative to bilateral resistance to trade with any single country, in estimating the determinants of trade with that country.|
|Multilateral trade liberalization||Reduction of tariffs and/or nontariff barriers by one or (usually) more countries on imports from all countries (or all members of the WTO). This is most likely to happen as a result of multilateral trade negotiations, such as the various GATT and WTO Rounds.|
|Multilateral trade negotiation||A trade negotiation involving a large number of countries, usually all of the signatories of the GATT or members of the WTO in the form of a GATT or WTO trade round.|
|Multilateral Trade Organization||The proposed name, during the Uruguay Round negotiations, for what ultimately became the World Trade Organization.|
|Multilateralism||The approach to trade policy and trade negotiations favoring agreements among all (or most) countries of the world at once, rather than only one or a small number at a time in separate bilateral, regional, or plurilateral agreements.|
|Multinational corporation||A corporation that operates in two or more countries. Since it is headquartered in only one country but has production or marketing facilities in others, it is the result of previous FDI.|
|Multinational enterprise||A firm, usually a corporation, that operates in two or more countries. In practice the term is used interchangeably with multinational corporation.|
|Multiple equilibria||Refers to a system in which there is more than one equilibrium, most simply a market in which a backward bending supply curve crosses a demand curve more than once, at prices each of which is a market-clearing price.|
|Multiple exchange rates||The existence of more than one exchange rate for a given pair of currencies. Rare today, this used to be common in countries with extensive capital controls, which also set different exchange rates for different purposes.|
|Multiplier||In Keynesian models, the ratio of change in an endogenous variable to change in an exogenous variable. Usually means the multiplier for government spending on income. In the simplest Keynesian model of a closed economy, this is 1/s, where s is the marginal propensity to save. See open economy multiplier.|
|Multistage production||Another term for fragmentation. Used by Dixit and Grossman (1982).|
|Mundell-Fleming Model||An open-economy version of the IS-LM model that allows for international trade and international capital flows. Due to Mundell (1962,63) and Fleming (1962).|
1. The specific factors model diagram, as attributed to Mussa (1974).
2. A diagram for explicating properties of the 2-factor H-O Model introduced by Mussa (1979). With factor prices on its axes, zero-profit curves for each sector show the determination of factor prices more directly than the Lerner Diagram, which serves much the same purposes.
|Mussa puzzle||The observation documented by Mussa (1986 that the variability over time of real exchange rates increases dramatically when industrial countries move from fixed to floating exchange rates. It is said to be a puzzle because the volatility is greater than can be explained by changes in domestic price levels.|
|Mutatis mutandis||Latin phrase meaning, approximately, "allowing other things to change accordingly." Used as a shorthand for indicating the effect of one economic variable on another, within a system in which other variables that matter will also change as a result. Contrasts with ceteris paribus.|
|Mutual recognition||The acceptance by one country of another country's certification that a satisfactory standard has been met for ability, performance, safety, etc.|
|Mystery of the missing trade||The empirical observation, by Trefler (1995), that the amount of trade is far less than predicted by the HOV version of the Heckscher-Ohlin Model. More precisely, the factor content of trade is far less than the differences between countries in their factor endowments.|
