Lerner paradox

Last updated

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. [1] [2] Abba Lerner showed the possibility in his 1936 article. [3]

Conditions

In the large country case of a perfectly competitive market, imposing tariffs reduces the world price of the import good, improving the tariff-imposing country's terms of trade. However, under certain conditions, tariffs can have an opposite effect. Therefore, it is called a paradox.

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.

<span class="mw-page-title-main">Free trade</span> Absence of government restriction on international 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.

Comparative advantage in an economic model is the advantage over others in producing a particular good. A good can be produced 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.

<span class="mw-page-title-main">Protectionism</span> Economic policy of regulating trade between states through government regulations

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 and raise government revenue. 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 against which the protections are implemented.

In economics, Dutch disease is the apparent causal relationship between the increase in the economic development of a specific sector and a decline in other sectors.

Factor price equalization is an economic theory, by Paul A. Samuelson (1948), which states that the prices of identical factors of production, such as the wage rate or the rent of capital, will be equalized across countries as a result of international trade in commodities. The theorem assumes that there are two goods and two factors of production, for example capital and labour. Other key assumptions of the theorem are that each country faces the same commodity prices, because of free trade in commodities, uses the same technology for production, and produces both goods. Crucially these assumptions result in factor prices being equalized across countries without the need for factor mobility, such as migration of labor or capital flows.

Welfare economics is a field of economics that applies microeconomic techniques to evaluate the overall well-being (welfare) of a society. This evaluation is typically done at the economy-wide level, and attempts to assess the distribution of resources and opportunities among members of society.

<span class="mw-page-title-main">Non-tariff barriers to trade</span> Type of trade barriers

Non-tariff barriers to trade are trade barriers that restrict imports or exports of goods or services through mechanisms other than the simple imposition of tariffs. Such barriers are subject to controversy and debate, as they may comply with international rules on trade yet serve protectionist purposes.

In economics, output is the quantity and quality of goods or services produced in a given time period, within a given economic network, whether consumed or used for further production. The economic network may be a firm, industry, or nation. The concept of national output is essential in the field of macroeconomics. It is national output that makes a country rich, not large amounts of money.

The Lerner symmetry theorem is a result used in international trade theory, which states that an ad valorem import tariff will have the same effects as an export tax. The theorem is based on the observation that the effect on relative prices is the same regardless of which policy is applied.

<span class="mw-page-title-main">Heckscher–Ohlin model</span> Economic model for international trade

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 the products which use their relatively abundant and cheap factors of production, and import the products which use the countries' relatively scarce factors.

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.

<span class="mw-page-title-main">Gravity model of trade</span> Bilateral trade flow model

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."

<span class="mw-page-title-main">Voluntary export restraint</span>

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, the Metzler paradox is the theoretical possibility that the imposition of a tariff on imports may reduce the relative internal price of that good. It was proposed by Lloyd Metzler in 1949 upon examination of tariffs within the Heckscher–Ohlin model. The paradox has roughly the same status as immiserizing growth and a transfer that makes the recipient worse off.

International trade theory is a sub-field of economics which analyzes the patterns of international trade, its origins, and its welfare implications. International trade policy has been highly controversial since the 18th century. International trade theory and economics itself have developed as means to evaluate the effects of trade policies.
