A customs union is generally defined as a type of trade bloc which is composed of a free trade area with a common external tariff.
A tariff is a tax imposed by the government of a country or by a supranational union on imports or exports of goods. Besides being a source of revenue for the government, import duties can also be a form of regulation of foreign trade and policy that taxes foreign products to encourage or safeguard domestic industry. Protective tariffs are among the most widely used instruments of protectionism, along with import quotas and export quotas and other non-tariff barriers to trade.
Free trade is a trade policy that does not restrict imports or exports. In government, free trade is predominantly advocated by political parties that hold economically liberal positions, while economic nationalist and left-wing political parties generally support protectionism, the opposite of free trade.
In an economic model, agents have a comparative advantage over others in producing a particular good if they can produce that good at a lower relative opportunity cost or autarky price, i.e. at a lower relative marginal cost prior to trade. Comparative advantage describes the economic reality of the work gains from trade for individuals, firms, or nations, which arise from differences in their factor endowments or technological progress.
Purchasing power parity (PPP) is a measure of the price of specific goods in different countries and is used to compare the absolute purchasing power of the countries' currencies. PPP is effectively the ratio of the price of a basket of goods at one location divided by the price of the basket of goods at a different location. The PPP inflation and exchange rate may differ from the market exchange rate because of tariffs, and other transaction costs.
Protectionism, sometimes referred to as trade protectionism, is the economic policy of restricting imports from other countries through methods such as tariffs on imported goods, import quotas, and a variety of other government regulations. Proponents argue that protectionist policies shield the producers, businesses, and workers of the import-competing sector in the country from foreign competitors. Opponents argue that protectionist policies reduce trade and adversely affect consumers in general as well as the producers and workers in export sectors, both in the country implementing protectionist policies and, in the countries, protected against.
In economics, the Dutch disease is the apparent causal relationship between the increase in the economic development of a specific sector and a decline in other sectors.
In macroeconomics and modern monetary policy, a devaluation is an official lowering of the value of a country's currency within a fixed exchange-rate system, in which a monetary authority formally sets a lower exchange rate of the national currency in relation to a foreign reference currency or currency basket. The opposite of devaluation, a change in the exchange rate making the domestic currency more expensive, is called a revaluation. A monetary authority maintains a fixed value of its currency by being ready to buy or sell foreign currency with the domestic currency at a stated rate; a devaluation is an indication that the monetary authority will buy and sell foreign currency at a lower rate.
The Rybczynski theorem was developed in 1955 by the Polish-born English economist Tadeusz Rybczynski (1923–1998). It states that at constant relative goods prices, a rise in the endowment of one factor will lead to a more than proportional expansion of the output in the sector which uses that factor intensively, and an absolute decline of the output of the other good.
International economics is concerned with the effects upon economic activity from international differences in productive resources and consumer preferences and the international institutions that affect them. It seeks to explain the patterns and consequences of transactions and interactions between the inhabitants of different countries, including trade, investment and transaction.
New trade theory (NTT) is a collection of economic models in international trade theory which focuses on the role of increasing returns to scale and network effects, which were originally developed in the late 1970s and early 1980s. The main motivation for the development of NTT was that, contrary to what traditional trade models would suggest, the majority of the world trade takes place between countries that are similar in terms of development, structure, and factor endowments.
Intra-industry trade refers to the exchange of similar products belonging to the same industry. The term is usually applied to international trade, where the same types of goods or services are both imported and exported.
The gravity model of international trade in international economics is a model that, in its traditional form, predicts bilateral trade flows based on the economic sizes and distance between two units. Research shows that there is "overwhelming evidence that trade tends to fall with distance."
A voluntary export restraint (VER) or voluntary export restriction is a measure by which the government or an industry in the importing country arranges with the government or the competing industry in the exporting country for a restriction on the volume of the latter's exports of one or more products.
In economics, gains from trade are the net benefits to economic agents from being allowed an increase in voluntary trading with each other. In technical terms, they are the increase of consumer surplus plus producer surplus from lower tariffs or otherwise liberalizing trade.
In economics, a tariff-rate quota (TRQ) is a two-tiered tariff system that combines import quotas and tariffs to regulate import products.
A commercial policy is a government's policy governing international trade. Commercial policy is an all encompassing term that is used to cover topics which involve international trade. Trade policy is often described in terms of a scale between the extremes of free trade on one side and protectionism on the other. A common commercial policy can sometimes be agreed by treaty within a customs union, as with the European Union's common commercial policy and in Mercosur. A nation's commercial policy will include and take into account the policies adopted by that nation's government while negotiating international trade. There are several factors that can affect a nation's commercial policy, all of which can affect international trade policies.

He served as the director of the International Trade and Investment Program at the National Bureau of Economic Research from 1992 to 2016. He also served as Associate Dean in the Social Sciences at the University of California, Davis from 2014 to 2019.
The Ricardo–Viner model, also known as the specific factors model, is an extension of the Ricardo model used in international trade theory. It was due to Jacob Viner's interest in explaining the migration of workers from the rural to urban areas after the Industrial revolution. Unlike the Ricardian model, the specific factors model allows for the existence of factors of production besides labor. In other words, labor is mobile, while the two other factors of production are immobile as opposed to the Ricardian model where labor is immobile internationally, but mobile between two sectors of an economy.
In economics, the Lerner paradox is the theoretical possibility that imposing tariffs raises the world price of the import good, causing a deterioration of the tariff-imposing country's terms of trade. Abba Lerner showed the possibility in his 1936 article.
