Iceberg transport cost 1. A cost of transporting a good that uses up some fraction of the good itself, rather than other resources. By analogy with floating an iceberg, costless except for the part of the iceberg that melts. Far from realistic, but a tractable way of modeling transport costs since it impacts no other market. Due to Samuelson (1954).
2. The economic parameter used to represent this cost in an economic model. It has become routine to use a number larger than one, the excess over one being the amount of the good used up in transport. Thus if iceberg cost is γ>1, then for each unit of a good to be delivered to its destination, γ must be shipped.

2. The Fisher price index because it lies between the upward-biased Laspeyre price index and the downward-biased Paache price index.
3. If the utility function is CES or Dixit-Stiglitz with n goods, prices pi, and elasticity of substitution σ, then the ideal price index is P = (Σi=1n pi1-σ)1/(1-σ).

Immigration The migration of people into a country.
Immigration Act of 1924 The Johnson-Reed Act that limited immigration into the US to specified quotas based on national origin. Limits were based on numbers of people already in the US as of 1890, before many came from Slavic countries and Italy, and the act banned all immigration from Asia. [Source]

Immiserizing Causing a person, group, or country to become worse off.
Immiserizing growth Economic growth that makes the country worse off. Bhagwati (1958) coined this term for growth that expands exports and worsens the terms of trade sufficiently that real income falls. Johnson (1955) had shown that a market distorted by a tariff could lose from growth and had also, independently, worked out conditions for Bhagwati's result. [Origin]
Immiserizing transfer A transfer that makes the receiving country worse off.

Import coverage ratio See coverage ratio.
Import demand elasticity The elasticity of demand for imports with respect to price.
Import deposit A requirement that importers put some amount of money in an account for some period of time. The purpose may be to assure that import duties will be paid, if they apply (as in the case of a tourist bringing in a car), or the deposit may simply be a nontariff barrier intended to discourage imports. See prior deposit.
Import Duties Act of 1932 Legislation by the UK parliament that placed a 10% tariff on almost all imports and permitted a commission to raise some tariffs thereafter. [Source]
Import duty A tariff on imports.
Import elasticity Usually means the import demand elasticity.
Import-export company A firm whose business consists mainly of international trade: buying goods in one country and selling them in another, thus both exporting and importing. Same as export-import company.
Import liberalization Trade liberalization
Import license The permit, or license, to import under an import quota or under exchange controls.
Import licensing See licensing.
Import Licensing Code A plurilateral agreement reached as part of the Tokyo Round to prevent import licensing procedures from unnecessarily hindering international trade.
Import monitoring A practice introduced by the US, first for steel and later for textiles and apparel, whereby the Department of Commerce records the volume of imports of specified products and makes these data publicly available. These procedures are intended to facilitate administered protection. See SIMA.
Import parity price The price that a purchaser pays or can expect to pay for an imported good, thus the c.i.f. import price plus tariff plus transport cost to the purchaser's location. This and the export parity price together define a range of the possible equilibrium prices for an equivalent domestically produced good.
Import penetration A measure of the importance of imports in the domestic economy, either by sector or overall, usually defined as the value of imports divided by the value of apparent consumption. Same as import share.
Import price ceiling An upper limit on the price of an imported good that is subject to a tariff. If the price exceeds that limit, "duties are refunded to importers." [Source]
Import price index Price index of the goods that a country imports.
Import promotion Any policy that encourages imports. A policy of export promotion generally has the side effect of stimulating imports as well. Today the term is more commonly used for policies used by developed countries intended to assist developing countries in exporting to them.

Import protection See protection.
Import quantity index Quantity index of the goods that a country imports.
Import quota See quota.

Import restriction Any measure to reduce imports, including a tariff or nontariff barrier.
Import sensitivity The extent to which an industry is vulnerable to losing sales, profits, or employment due to an increase in imports.
Import share The fraction of domestic purchases in an industry that are spent on imports. Same as import penetration.
Import substitute A good produced domestically that competes with imports, either as a perfect substitute or as a differentiated product.
Import substituting industrialization Import substitution. (ISI)
Import substitution A strategy for economic development that replaces imports with domestic production. It may be motivated by the infant industry argument, or simply by a desire to mimic the industrial structure of advanced countries. Contrasts with export promotion.
Import surcharge 1. A tax levied uniformly on most or all imports, in addition to already existing tariffs.

2. The extra cost per unit of an import imposed on the importer in order to satisfy some requirement, such as a technical barrier to trade.
Impressment The act of violently forcing unwilling men into military or naval service.
Improve the terms of trade To increase the value of the terms of trade; that is, to raise the relative price of exports compared to imports. As an increase in what the country gets in return for what it gives up, this is associated with improving country's welfare, though whether that actually occurs depends on why prices change.
Improve the trade balance This usually means a rise in exports relative to imports, thus making the balance of trade larger if positive or smaller if negative. The terminology ignores that exports use resources while imports meet domestic needs, reflecting instead the association of exports with either accumulation of wealth or jobs.
In kind Referring to a payment made with goods instead of money.
Inada conditions Two conditions often assumed of production and sometimes utility functions to assure the existence of optimal interior solutions. The two conditions are that the objective function have infinite slope at zero and zero slope at infinity. Due to Inada (1963).

2. National income.
3. The return earned on an asset per unit time.
Income disparity Inequality of income, usually referring to differences in average per capita incomes across countries.
Income distribution The fractions of a population that are at various levels of income. Larger differences in income are said to be "worse" and smaller are "better." International trade and factor movements can alter countries' income distributions by changing prices of low- and high-paid factors.
Income effect 1. That portion of the effect of price on quantity demanded that reflects the change in real income due to the price change. Contrasts with substitution effect.
2. Any change that is due to a change in income.
Income elastic Having an income elasticity greater than one. Contrasts with income inelastic.
Income elasticity Normally the income elasticity of demand; that is, the elasticity of demand with respect to income.
Income-expenditure analysis The simplest Keynesian model for determining national income, in which desired expenditure (consumption plus investment plus government purchases) in equilibrium depends on income. Gives rise to the income-expenditure multiplier.
Income inelastic Having an income elasticity less than one. Contrasts with income elastic.
Income redistribution argument for a tariff The argument that tariffs should be used in order to redistribute income towards the poor. In a rich country, where unskilled labor is the scarce factor, this can make sense as explained in the Stolper-Samuelson Theorem, but it is a second-best argument.
Income tax A tax levied on incomes of persons or corporations. International differences in income tax rates sometimes induce persons and corporations to relocate to lower-tax jurisdictions.
Income terms of trade The purchasing power, in terms of the price of imports, Pm, of the value (price times quantity) of a country's exports: ITT = PxQx/Pm. Concept and term were introduced by Dorrance (1948). [Origin]

Increasing cost 1. Referring to a single firm or industry, the rise in cost of production that occurs when output is increased by expanding variable inputs while holding some fixed input constant. A corollary of the Law of Diminishing Returns.
2. In general equilibrium, increasing opportunity cost.
Increasing opportunity cost The characteristic of an economy that the opportunity cost of a good rises as more is produced, resulting in a transformation curve that is concave to the origin. In the HO Model, this happens in spite of CRTS if sectors have different factor intensities.
Increasing returns industry An industry whose technology displays substantial increasing returns to scale. Such an industry may be a natural monopoly. It also may provide an argument for industrial policy to induce such an industry to locate in the domestic economy rather than abroad.
Increasing returns to scale A property of a production function such that changing all inputs by the same proportion changes output more than in proportion. Common forms include homogeneous of degree greater than one and production with constant marginal cost but positive fixed cost. Also called economies of scale, scale economies, and simply increasing returns. Contrasts with decreasing returns and constant returns.
Incremental capital output ratio The amount of additional capital that a developing country requires to increase its output by one unit; thus the reciprocal of the marginal product of capital. Used as an (inverse) indicator of how efficiently a country is using the scarce capital it acquires.
Indebtedness The amount that is owed; thus amount of an entity's (individual, firm, or government) financial obligations to creditors.

Index A quantitative measure, usually of something the measurement of which is not straightforward, such as an average of many diverse prices, or a concept such as economic development or human rights.
Index number A numerical index, usually indicating, by comparison with a base value of 100, the size of the index relative to a base year or other benchmark for comparison. Thus, for example, a CPI of 115 in 2004 with a base year of 1999 means that prices have risen 15% from 1999 to 2004.
Index number problem A question the answer to which depends on a choice of weights. E.g., the effect of trade on the real wage of labor in the specific factors model is an index number problem, depending on how much workers consume of (lower-priced) imported and (higher-priced) exported goods.
Index of openness Openness index
Index of sustainable economic welfare An alternative to GDP intended as a measure of welfare rather than simply production. As such it would take account of such things as income distribution, environmental impact, and leisure. No single measure of ISEW seems to have been agreed upon.
Indian Institute of Foreign Trade "Established in 1963 as an autonomous body under the Ministry of Commerce & Industry to contribute in the skill building for the external trade sector of India.""
Indifference curve A means of representing the preferences and well-being of consumers. Formally, it is a curve representing the combinations of arguments in a utility function that yield a given level of utility and therefore among which a consumer with that utility function would be indifferent.
Indigenous innovation policy A policy introduced by China in 2009 requiring that purchases by government agencies favor products whose intellectual property has been developed, owned, and registered in China.
Indirect exchange rate The foreign-currency price of a unit of domestic currency. (This definition appears in several places, but it is a mystery to me why this is any less direct than its reciprocal.)
Indirect export Export of a good by someone other than the firm that produced it, such as by a trading company or by a foreign purchaser.
Indirect export subsidy An upstream subsidy.
Indirect tax A tax levied on expenditure, such as a sales tax, excise tax, or value added tax. Contrasts with direct tax.

Indo-Pacific Term for the "conjoined perspective on the Indian Ocean and the even vaster Pacific" had its first recorded use in the mid-19th century by "a British colonial lawyer and ethnographer." [Source]
Indo-Pacific Economic Framework The Indo-Pacific Economic Framework for Prosperity was launched by the United States in May 2022 with 13 countries of the Asia-Pacific to "advance resilience, sustainability, inclusiveness, economic growth, fairness, and competitiveness." Not a formal trade agreement, it is not clear what it will accomplish.
Industrial concentration The extent to which a small number of firms dominates an industry, often measured by a concentration ratio or by a Herfindahl index. Concentration is, in effect, the opposite of competition, although in an open economy imports complicate the relationship.
Industrial policy Government policy to influence which industries expand and, perhaps implicitly, which contract, via subsidies, tax breaks, and other aids to favored industries. The purpose, aside from political favor, may be to foster competitive advantage where there are beneficial externalities and/or scale economies.
Industrial targeting Industrial policy
Industrialization The establishment and subsequent growth of industrial production in a country, usually meaning heavy manufacturing.
Industrialized Having experienced substantial industrialization. Industrialized countries are usually the same as developed countries.
Industry 1. The portion of an economy that produces a particular related group of products; e.g., the motor vehicle industry, the tourism industry, and the mining industry. A list of industries might well include agriculture.
2. One of three main sectors of an economy, the other two being the agriculture and service sectors. Industry in turn includes mining and manufacturing.
Inelastic Elasticity less than one. For price elasticity of demand, it means expenditure falls as price falls. For income elasticity it means expenditure share falls as income rises. Contrasts with elastic and unit elastic.
Inelastic offer curve An offer curve with inelastic demand for imports. That inelasticity implies that exports decline as imports increase, and therefore that the offer curve is backward bending. Strictly speaking, the natural definition of an offer curve's elasticity would be negative in this case, not just less than one, but that definition is seldom used.
Inequality Differences in per capita income or household income across populations within a country or across countries.
Infant industry A newly established domestic industry that is less productive than foreign producers.
Infant industry argument The theoretical rationale for infant industry protection.
Infant industry protection Protection to sustain an infant industry. If productivity rises with experience, as with learning by doing or dynamic economies of scale, enough to pass Mill's and Bastable's tests, there is a second-best argument for protection. The term is very old and the idea older, but a classic treatment may be found in Baldwin (1969). [Origin]
Inferior good A good the demand for which falls as income rises. The income elasticity of demand is therefore negative. Contrasts with normal good.
Infinitely elastic Having an elasticity that is infinitely large, usually with respect to price, in which case what it means in effect is that the price is constant, given, or fixed. A small open economy, usually by definition, faces world supply and demand that are infinitely elastic at a given world price.
Inflation Increase in the overall price level of an economy, usually as measured by the CPI or by the implicit price deflator.
Inflation adjusted Adjusted for inflation.
Inflation rate The percentage increase in the price level per year. See inflation.
Inflation Reduction Act US legislation of August 16, 2022, that "directs new federal spending toward reducing carbon emissions, lowering healthcare costs, funding the Internal Revenue Service, and improving taxpayer compliance." In spite of its name, its main initiative is to subsidize green technologies in the US. [Source]
Inflation targeting A principle of monetary policy that the rate of inflation should be kept within a pre-specified range, using expansionary policy when the rate is below that range and contractionary policy above it.
Inflation tax The use of monetary expansion and consequent inflation to finance a government deficit by reducing the real value of outstanding nominal debt. Foreign holders of debt bear the tax, without experiencing inflation, due to exchange rate depreciation.
Inflow See capital inflow.
Informal trade The movement of goods across borders without passing through customs and being recorded in trade statistics. Especially common in Africa, where borders are easily crossed, it is smuggling that governments ignore, as their poor rely on it for their livelihoods.
Information Technology Agreement A plurilateral agreement within the WTO, concluded in 1996 and expanded inn 2015, providing for participants to completely eliminate tariffs on specified IT products. As of February 2024, the agreement had 82 participants, covering about 97% of trade in these products.
Information Technology Agreement Expansion An expansion of the 1996 ITA, agreed by 50 WTO members at the Nairobi Ministerial in December 2015, expanding and updating the list of products covered.
Information Technology Product Any product commonly classed as "high technology," including (as listed in the explanation of the ITA, "computers, telecommunication equipment, semiconductors, semiconductor manufacturing and testing equipment, software, scientific instruments, as well as most of the parts and accessories of these products."
Inframarginal Inside of, as opposed to at, the margin. Example: for a firm that is producing 100 units, marginal cost is the cost of the 101st unit, while inframarginal cost refers, usually only qualitatively and without a precise definition, to the cost of units 1,...,100.
Inframarginal rent The quasi rent earned by a perfectly competitive firm in the short run. If price equals marginal cost, then it earns nothing on the marginal unit, but if marginal cost increases with output due to a fixed factor, then price exceeds marginal cost for inframarginal units.
Infrastructure The facilities that must be in place in order for a country or area to function as an economy and as a state, including the capital needed for transportation, communication, and provision of water and power, and the institutions needed for security, health, and education.
Infrastructure Investment and Jobs Act US bipartisan legislation passed in 2021 that provided $1.2 trillion over five years for infrastructure. It "made trade agreements and reciprocal defense procurement agreements exceptions to the BAA." It "applied a domestic purchasing requirement to construction materials for the first time." [Source]
Injury Harm to an industry's owners and/or workers. Import protection under the safeguards, AD, and CVD provisions of the GATT require a finding of serious (for safeguards) or material (for AD/CVD) injury. In the US, these are determined by the USITC.
Injury margin In cases of anti-dumping and countervailing duties, the difference between the import price and the price that would be needed to prevent injury.
Injury test The determination by an administrative authority, in a request for administered protection, of whether the domestic industry has experienced sufficient injury to meet the requirement of the protection requested: material injury in cases of unfair trade or serious injury in cases of safeguards.

Intergovernmental organization An organization the members of which are national governments. Examples include the United Nations, its many subsidiary organizations such as UNCTAD, and a great many others.
Inter-industry trade Trade in which a country's exports and imports are in different industries. Typical of models of comparative advantage, such as the Ricardian Model and Heckscher-Ohlin Model. Contrasts with intra-industry trade.
Intermediate good Same as intermediate input.
Intermediate input An input to production that has itself been produced and that, unlike capital, is used up in production. As an input it is in contrast to a primary input and as an output it is in contrast to a final good. A very large portion of international trade is in intermediate inputs.
Intermediate transaction The sale of a product by one firm to another, presumably to be used as an intermediate input.
Intermestic Denoting a blend of both international and domestic, this is used to indicate that many apparently international issues and policies have domestic implications, and vice versa. [Origin]
