|Segmented markets||The situation in which two or more markets for the same product are separated such that buyers in one market cannot buy in the other, thus permitting each market to sustain a different price. Models of international oligopoly often assume this.|
|Seigniorage||The difference between what money can buy and its cost of production. Thus, seigniorage is the benefit that a government or other monetary authority gets from creating money. Internationally, if one country's money is willingly held by another, the first gets seigniorage. This is the case of a reserve currency.|

|Shift parameter||A parameter that determines only the position of a function, not its slope or shape, usually just by increasing the function's value. For example, in the consumption function C=C0+cY, C0 and c are both parameters, but C0 is a shift parameter that can be useful for analyzing a change in the desire to consume.|
|Shipper||The firm or other entity that purchases shipping services. In the context of international trade, it may be either the exporter or the importer.|
|Shipping the good apples out||See Alchian-Allen Theorem.|
|Shipping service||The act of transporting a good from one location to another on behalf of a client. Shipping service need not be by sea, but could be by air, land, water, or a combination of these.|

|Stabilizing speculation||Speculation that decreases the movements of the price in the market where the speculation occurs. See destabilizing speculation. Friedman (1953) provided a classic argument that profitable speculation on a floating exchange rate would be stabilizing.|
1. Of an equilibrium, that the dynamic adjustment away from equilibrium converges to the equilibrium.
2. Of an economic variable, not subject to large or erratic fluctuations.
|Stackelberg equilibrium||A game theoretic equilibrium in which one player acts as a leader and another as a follower, the leader setting strategy taking account of the follower's optimal response. Contrasts with Nash equilibrium in which both players take the other's strategy as given. Due to Stackelberg (1934).|
|Stagflation||The combination of high or increasing inflation with high or increasing unemployment (stagnation). Said to be due to Iain Macleod, who later would become Britain's Chancellor of the Exchequer, in a speech to Parliament in 1965.|

|Standard deviation||A common measure of the dispersion of a random variable or of a sample of data. Defined as the square root of the variance.|
|Standard error||A common measure of the uncertainty associated with a numerical estimate, equal to the standard deviation of the associated error. In a regression analysis, standard errors are reported with (or below) the coefficient estimates. As a rough guide, one can be 95% confident that the true value is within ±2 standard errors of the estimate.|

|Standard trade model||There is probably no agreement as to what should be considered the "standard" trade model. But Krugman and Obstfeld (1991), which has been widely used through many editions, gives this name to a model with perfect competition, a curved PPF, and consumer preferences that can be represented by community indifference curves. It therefore includes the H-O Model and specific factors model as special cases.|
1. Conformity to a common set of specifications, so that all units of a product, from a given producer or from multiple producers, are compatible and can serve the same purpose.
2. Conformity to an exacting set of specifications with regard to quality, such as the ISO 9000 standards established maintained by the International Organization for Standardization.

|Staple theory of economic growth||A theory of growth based on production and export of "staples" -- which seems, in this context, to mean raw materials. The theory was designed for understanding the early history of Canada, and is said to be most relevant for economies with abundant open land. See Watkins (1963).|
|Starrett's Impossibility Theorem||The Spatial Impossibility Theorem of Starrett (1978) that an economy with a finite number of locations and positive, resource-using transport costs cannot possess a competitive equilibrium. This may account, implicitly, for the neglect of transport costs in competitive trade theory.|
|State bank||A bank owned by a government, other than the central bank, and performing the same functions as a commercial bank. Thus a bank that is an SOE. State banks are often directed by their governments to provide credit to activities or persons favored by the government.|
|State capitalism||A system in which the government plays a large and active role in the economy, owning large enterprises and using their influence in markets for political rather than purely economic ends.|
|State-owned enterprise||A firm owned by government. Relations between SOEs and private firms on international markets raise special problems for GATT, since SOEs may not respond normally to market forces and their actions may reflect government policies.|
|State trading enterprise||An entity of government that is responsible for exporting and/or importing specified products. See marketing board.|
|Static comparative advantage||The normal concept of comparative advantage, as opposed to dynamic comparative advantage.|
|Static gains from trade||The economic benefits from trade in static models: efficiency gains from exploiting comparative advantage; scale economies; reduction in distortion due to imperfect competition; increased product variety; and the productivity effect. Contrasts with dynamic gains from trade.|
|Static model||An economic model with no explicit time dimension. A static model abstracts from the adjustment to an equilibrium or optimum over time, as well as from dependence of variables in the model on a changing past or future. Contrasts with dynamic model.|
|Statistical Classification of Economic Activities in the European Community||Called NACE, this is the uniform classification system used in all member states of the European Union.|
|Statistical Classification of Products by Activity||See Classification of Products by Activity.|

|Sterilize||To use offsetting open market operations to prevent an act of exchange market intervention from changing the monetary base. With sterilization, any purchase of foreign exchange is accompanied by an equal-value sale of domestic bonds, and vice versa.|
|Sterilized intervention||Exchange market intervention that is sterilized.|
|Sterling||British money, particularly the British pound, a formal name for which is the pound sterling.|
|Sterling Area||The group of countries that either used the British pound as their currency or pegged their currencies to the British pound. Most were current or former colonies of the United Kingdom. The sterling area ceased to be meaningful in the 1970s when countries largely switched to floating exchange rates.|
|Sticky price model||A model in which one or more prices are assumed not to change when the markets in which they apply move out of equilibrium. Internationally, this can result in a violation of the law of one price.|

1. A share in the ownership of a corporation.
2. A stock, or stock variable, is an economic magnitude that describes a quantity that exists at a point in time. Examples include a country's international reserves, a consumer's wealth, and a country's labor force. Contrasts with a flow.
|Stock market value||The total value of outstanding shares of stock of a firm at the price currently prevailing in the stock market.|
|Stockpiling||The storage of something in order to have it available in the future if the need for it increases. In international economics, stockpiling may occur for speculative purposes; by governments to provide for national security; and by central banks managing international reserves.|
|Stolper-Samuelson derivative||In general equilibrium, the effect of a small change in the price of a single good on the price of a factor of production.|
1. The proposition of the H-O Model that a rise in the relative price of a good raises the real wage of the factor used intensively in that industry and lowers the real wage of the other factor.
2. The further proposition (requiring additional assumptions) that protection raises the real wage of a country's scarce factor and lowers the real wage of its abundant factor. Due to Stolper and Samuelson (1941).
|Store of value||One of three basic properties of money: the ability to retain value over time, and therefore to be useful for those who wish to sell something now and not spend the proceeds until later.|
|Straight-line PPF||The PPF that arises always in the Ricardian Model, or as a special case in the H-O Model if the two sectors have the same factor intensity. It is a downward sloping straight line with, therefore, a constant marginal rate of transformation.|
|Strategic and Economic Dialogue||The US-China Strategic and Economic Dialogue, S&ED.|
|Strategic industry argument for a tariff||The view that an industry serves a special "strategic" purpose in an economy and needs to be protected by a tariff to prevent it from disappearing. Views of what constitutes a strategic purpose are often vague and contradictory. The use of a tariff for this purpose is second best.|
|Strategic partnership||An alliance between organizations to achieve some objective. For example, two corporations, often from different countries, may work together on a product that combines their separate areas of expertise.|
|Strategic Petroleum Reserve||The strategic stockpile of oil held by the United States government.|
|Strategic stockpile||An accumulation of a commodity by a government to be used in case of a disruption of supply due to war or other emergency.|
|Strategic trade policy||The use of trade policies, including tariffs, subsidies, and even export subsidies, in a context of imperfect competition and/or increasing returns to scale to alter the outcome of international competition in a country's favor, usually by allowing its firms a larger share of industry profits. The seminal contribution was Brander and Spencer (1981).|
|Strategic trade policy argument for a tariff||In an example of strategic trade policy, the use of a tariff to extract monopoly profits from a foreign monopolist, or to shift profit from foreign to domestic competitors in an international oligopoly. The monopoly case seems to have originated with Katrak (1977), but the classic treatment of the larger issue is Brander and Spencer (1984).|
|Strategic variable||An economic variable that is chosen with regard to, and sometimes with a view to influencing, economic behavior by someone else. Most frequently refers to the choice of firms in an oligopoly.|
|Strategy||In game theory, a set of actions and contingent actions for the several stages of a sequential game. That is, a plan of action for each stage contingent on the outcome of preceeding stages.|
|Structural adjustment||The reallocation of resources (labor and capital) among sectors of the economy in response to changing economic circumstances, including trading conditions, or changes in policy.|
|Structural adjustment program||The list of budgetary and policy changes required by the IMF and/or World Bank in order for a developing country to qualify for a loan. This "conditionality" typically includes reducing barriers to trade and capital flows, tax increases, and cuts in government spending.|
1. A permanent change in the structure of an economy, such as a shift in preferences or technology, that causes a permanent change in relative sizes of various industries and a consequent re-allocation of labor among them.
2. In econometric time series, a change at some time in the parameters that generate the series.
|Structural Impediments Initiative||A 1990 agreement between the United States and Japan to reduce their bilateral trade imbalance. Among other commitments, the U.S. promised to reduce its budget deficit and encourage saving, while Japan promised to increase spending and facilitate entry of new businesses.|
|Structural unemployment||Unemployment that results from a mismatch between supply and demand for workers. That is, workers who cannot find jobs, not because there are no jobs, but because they are not qualified for the jobs that are available.|
|Structure of protection||The pattern of protection across sectors of an economy: which sectors are highly protected and which are not, perhaps in terms of effective protection, or - even better - in terms of their expansion or contraction that would occur if all protection were to be removed.|
|Stumbling bloc||The term that Bhagwati (1991) used, together with building bloc(k) or stepping stone, to address whether PTAs help move the world toward or away from multilateral free trade. Also written as "stumbling block".|
|Stumpage||See softwood lumber dispute.|
|Stylized fact||Something that has been observed to be true, or close to true, sufficiently often and in enough different contexts that an economic theory should be consistent with it. Those who present a set of stylized facts typically do not support them with data, but simply list them to motivate their theoretical analysis.|
|Subcontracting||Delegation by one firm of a portion of its production process, under contract, to another firm, perhaps in another country. A form of fragmentation.|
|Subgame||A portion of a game that is itself a game.|
|Subgame perfect||Said of a Nash equilibrium if the portions of the strategies of that equilibrium that pertain to each subgame are also Nash for their subgame. This is a useful refinement of Nash equilibrium in that it rules out strategies that are not credible for subgames.|
|Subsidiary||A firm that is owned and ultimately controlled by another firm. Thus a multinational corporation has a parent in one country and one or more subsidiaries in others.|
|Subsidy||A payment by government, perhaps implicit, to the private sector in return for some activity that it wants to reward, encourage, or assist. Under WTO rules, subsidies may be prohibited, actionable, or non-actionable.|
|Subsidy equivalent||The size of the direct cash subsidy that would have the same effect on behavior -- usually production but sometimes consumption -- as some other policy. See producer subsidy equivalent.|
|Subsistence economy||An economy composed mostly of subsistence farmers.|
1. Literally, a farmer who produces mostly only for the consumption of the farmer's own household.
2. The term also seems to be used for farmers who grow a crop to sell, but whose income from doing so barely allows them to survive. When trade or trade policy is said to hurt subsistence farmers, it must be under this definition.
1. Two goods are substitues if they serve largely the same purposes, so that one can be used or consumed in place of the other.
2. Formally, one good is a substitute for another if an increase in demand for one (or a fall in its price) causes a decrease in demand for the other. Opposite of complement.
|Substitute in production||One good is a substitute for another in production if an increase in output of one (or a rise in its price) causes a decrease in output of the other.|
|Substitution effect||That portion of the effect of price on quantity demanded that reflects the changed tradeoff between the cost of the good and the costs of other alternatives. Contrasts with income effect.|
|Sudden stop||A large negative swing in capital inflows, such as emerging markets especially may experience if they have financed current account deficits with short-term borrowing. Term is due to Calvo (1998).|
|Sunk cost||A cost that has already been incurred and cannot be reversed, which therefore cannot be avoided by current or future action. Sunk costs should therefore be irrelevant to current decisions.|
|Sunrise industry||An industry that is new and expected to grow rapidly, often through high technology. Contrasts with sunset industry. Differs also from infant industry, which is presumed to be weak and need assistance.|
|Sunset clause||A provision within a piece of legislation providing for its expiration on a specified date unless it is deliberately renewed.|
|Sunset industry argument||The argument, in contrast to the infant industry argument, that a mature industry should be provided protection, either to help it restore its competitiveness, or to cushion its exit from the economy.|
|Super 301||A U.S. law authorizing USTR to identify the most significant unfair trade practices confronting U.S. exports and to seek to eliminate them. In contrast to Section 301, this does not require a private party to initiate the action.|
|Superior good||A good the demand for which is income elastic, so that consumers spend a larger fraction of income on it as income rises.|
|Supernatural trading bloc||A trading bloc among countries that are natural trading partners but that, because its tariff preferences are too extreme or transport costs with the outside world are too low, reduces world welfare. Due to Frankel (1997).|
|Superstar||See export superstar|
|Supplier surplus||Same as producer surplus, but recognizing that suppliers in some markets are not producers, even though the concept remains valid as measuring benefit to suppliers.|
1. The act of offering a product for sale.
2. The quantity offered for sale.
3. The quantities offered for sale at various prices; the supply curve.
|Supply chain||The sequence of steps, often done in different firms and/or locations, needed to produce a final good from primary factors, starting with processing of raw materials, continuing with production of perhaps a series of intermediate inputs, and ending with final assembly and distribution.|
|Supply curve||The graph of quantity supplied as a function of price, normally upward sloping, straight or curved, and drawn with quantity on the horizontal axis and price on the vertical axis. Supply curves for exports and for foreign exchange usually have the same qualitative properties as supply curves for labor, being potentially backward bending.|
|Supply elasticity||The elasticity of a supply function, usually with respect to price.|
|Supply function||The mathematical function explaining the quantity supplied in terms of its various determinants, including price; thus the algebraic representation of the supply curve.|
|Supply price||The price at which a given quantity is supplied; thus the supply curve viewed from the perspective of price as a function of quantity. This is not well defined if the supply curve is backward bending.|
|Supply shock||A shock on the supply side of a market. Thus an unexpected shift, up or down, in the supply curve.|
|Supply side||Anything that contributes to supply, as opposed to demand, in a market or, especially, in the aggregate economy; aggregate supply.|
|Supply side constraint||This typically refers to any of a list of reasons why a developing country may find it hard to exploit its comparative advantage if it were to liberalize trade. The list includes inadequate infrastructure, low productivity, and lack of information about markets. Some reflect legitimate needs for trade facilitation; others are just excuses for protectionism.|
|Support price||The price guaranteed by a government price support program. Typically it requires that the government buy the product at that price. If the market clearing price is lower, this raises the price to that level and causes the government to acquire the resulting excess supply.|
|Supranational||Transcending nations, especially through organizations that encompass more than one nation, such as the European Union|
|Surcharge||See import surcharge.|
|Surplus||In the balance of payments, or in any category of international transactions within it, the surplus is the sum of credits minus the sum of debits. Also called the "balance" for that category. Thus the balance of trade is the same as the trade surplus, and similarly for merchandise trade, current account, and financial account.|
|Suspension||See duty suspension.|
|Suspension agreement||An agreement between an importing government and a foreign exporting firm to limit its exports and thus forestall the levying of anti-dumping duties or countervailing duties.|
|Sustainable development||Economic development that is achieved without undermining the incomes, resources, or environment of future generations.|

|Sustainable Economic Development Assessment||A measure of well-being based on 43 indicators in 148 countries (as of March 2016) produced by the Boston Consulting Group.|
|Swan diagram||A diagram illustrating the conflict between internal balance and external balance as they respond to a country's fiscal deficit and its costs relative to the world (and thus its exchange rate.) Due to Swan (1955).|
1. In exchange markets, this is a simultaneous sale of a currency on the spot market together with a purchase of the same amount on the forward market. By combining these two transactions into a single one, transaction costs may be reduced.
2. An arrangement between two central banks whereby they each agree to lend their currency to the other.
|Swap rate||The difference between the spot and forward exchange rates. Thus the price of a swap.|
|Swap scheme||A form of countertrade in which goods are exchanged for goods, but at different locations so as to reduce transport costs.|
|Sweatshop||A manufacturing workplace that treats its workers inhumanely, paying low wages, imposing harsh and unsafe working conditions, and demanding levels of performance that are harmful to the workers.|
|SWF||Sovereign wealth fund|
|SWIFT||Originally the Society for Worldwide International Financial Communication, now just called SWIFT, this is a member-owned cooperative of financial institutions that provides a platform for exchanging financial information. Its SWIFT Codes are used for transmitting funds among banks internationally.|
|Swiss formula||A formula devised during the Tokyo Round for reducing tariffs in a manner that would harmonize them. The formula is tnew=(toldM)/(told+M), where the t's are the new and old tariffs, in percent, and M is the maximum possible new tariff. Somebody, presumably Swiss, was very clever! Contrasts with a linear cut.|
|Switch trading||A form of countertrade in which a buyer in one country of exports from a second pays for it with an obligation due from a third party.|
|Systematic Integrated Framework for Trade Analysis||Trade SIFT is a tool for trade policy analysis, incorporating data on trade and trade barriers together with facilities to calculate and display various standard indicators from those data, such as revealed comparative advantage and the Grubel-Lloyd index of intra-industry trade.|
|Systemic 5||The group of five economies -- China, Euro Area, Japan, United Kingdom, and the United States -- identified by the IMF as crucial for the stability of the world economy due to macroeconomic spillovers to other countries.|
