In economics, a commodity is an economic good or service that has full or substantial fungibility: that is, the market treats instances of the good as equivalent or nearly so with no regard to who produced them. Most commodities are raw materials, basic resources, agricultural, or mining products, such as iron ore, sugar, or grains like rice and wheat. Commodities can also be mass-produced unspecialized products such as chemicals and computer memory.
Purchasing power parity (PPP) is a way of measuring economic variables in different countries so that irrelevant exchange rate variations do not distort comparisons. Purchasing power exchange rates are such that it would cost exactly the same number of, for example, US dollars to buy euros and then buy a basket of goods in the market as it would cost to purchase the same goods directly with dollars. The purchasing power exchange rate used in this conversion equals the ratio of the currencies' respective purchasing powers.
A grey or gray market refers to the trade of a commodity through distribution channels that are legal but unintended by the original manufacturer or trade mark proprietor. Grey market products are products sold by a manufacturer or their authorized agent outside the terms of the agreement between the reseller and the manufacturer.
In economics, the Prebisch–Singer hypothesis argues that the price of primary commodities declines relative to the price of manufactured goods over the long term, which causes the terms of trade of primary-product-based economies to deteriorate. As of 2013, recent statistical studies have given support for the idea. The idea was developed by Raúl Prebisch and Hans Singer in the late 1940s; since that time, it has served as a major pillar of dependency theory and policies such as import substitution industrialization (ISI).
An export in international trade is a good or service produced in one country that is bought by someone in another country. The seller of such goods and services is an exporter; the foreign buyer is an importer.
The terms of trade (TOT) is the relative price of imports in terms of exports and is defined as the ratio of export prices to import prices. It can be interpreted as the amount of import goods an economy can purchase per unit of export goods.
Trade barriers are government-induced restrictions on international trade.
Non-tariff barriers to trade (NTBs) or sometimes called "Non-Tariff Measures (NTMs)" are trade barriers that restrict imports or exports of goods or services through mechanisms other than the simple imposition of tariffs.
The Heckscher–Ohlin model is a general equilibrium mathematical model of international trade, developed by Eli Heckscher and Bertil Ohlin at the Stockholm School of Economics. It builds on David Ricardo's theory of comparative advantage by predicting patterns of commerce and production based on the factor endowments of a trading region. The model essentially says that countries export products that use their abundant and cheap factors of production, and import products that use the countries' scarce factors.
Export subsidy is a government policy to encourage export of goods and discourage sale of goods on the domestic market through direct payments, low-cost loans, tax relief for exporters, or government-financed international advertising. An export subsidy reduces the price paid by foreign importers, which means domestic consumers pay more than foreign consumers. The World Trade Organization (WTO) prohibits most subsidies directly linked to the volume of exports, except for LDCs. Incentives are given by the government of a country to exporters to encourage export of goods.
A bonded warehouse, or bond, is a building or other secured area in which dutiable goods may be stored, manipulated, or undergo manufacturing operations without payment of duty. It may be managed by the state or by private enterprise. In the latter case a customs bond must be posted with the government. This system exists in all developed countries of the world.
Unequal exchange is a much disputed concept which is used primarily in Marxist economics, but also in ecological economics, to denote forms of exploitation hidden in or underwriting trade. Originating, in the wake of the debate on the Singer-Prebisch thesis, as an explanation of the falling terms of trade for underdeveloped countries, the concept was coined in 1962 by the Greco-French economist Arghiri Emmanuel to denote an exchange taking place where the rate of profit has been internationally equalised, but wage-levels have not. It has since acquired a variety of meanings, often linked to other or older traditions which perhaps then raise claims to priority.
A market is one of the many varieties of systems, institutions, procedures, social relations and infrastructures whereby parties engage in exchange. While parties may exchange goods and services by barter, most markets rely on sellers offering their goods or services in exchange for money from buyers. It can be said that a market is the process by which the prices of goods and services are established. Markets facilitate trade and enable the distribution and resource allocation in a society. Markets allow any trade-able item to be evaluated and priced. A market emerges more or less spontaneously or may be constructed deliberately by human interaction in order to enable the exchange of rights of services and goods. Markets generally supplant gift economies and are often held in place through rules and customs, such as a booth fee, competitive pricing, and source of goods for sale.
An import is a good brought into a jurisdiction, especially across a national border, from an external source. The party bringing in the good is called an importer. An import in the receiving country is an export from the sending country. Importation and exportation are the defining financial transactions of international trade.
Monetary inflation is a sustained increase in the money supply of a country. Depending on many factors, especially public expectations, the fundamental state and development of the economy, and the transmission mechanism, it is likely to result in price inflation, which is usually just called "inflation", which is a rise in the general level of prices of goods and services.
In classical political economy and especially Karl Marx's critique of political economy, a commodity is any good or service produced by human labour and offered as a product for general sale on the market. Some other priced goods are also treated as commodities, e.g. human labor-power, works of art and natural resources, even though they may not be produced specifically for the market, or be non-reproducible goods.
Trade is a key factor of the economy of China. In the twenty-five years that followed after the Communist takeover in 1949, China's trade institutions developed into a partially modern but somewhat inefficient system. The drive to modernize the economy that began in 1978 required a sharp acceleration in commodity flows and greatly improved efficiency in economic transactions. In the ensuing years economic reforms were adopted by the government to develop a socialist market economy. This type of economy combined central planning with market mechanisms. The changes resulted in the decentralization and expansion of domestic and foreign trade institutions, as well as a greatly enlarged role for free markets in the distribution of goods, and a prominent role for foreign trade and investment in economic development.
The Ministry of Commerce of Iran was the main organ of the Government in charge of the regulation and implementation of policies applicable to domestic and foreign trade. This includes:
Inflation rate in India was 3.78% as of August 2015, as per the Indian Ministry of Statistics and Programme Implementation. This represents a modest reduction from the previous annual figure of 9.6% for June 2011. Inflation rates in India are usually quoted as changes in the Wholesale Price Index (WPI), for all commodities
Import parity price or IPP is defined as, “The price that a purchaser pays or can expect to pay for imported goods; 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 equivalent domestically produced goods”.
