Lerner Paradox
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.Grossman, G. (2016"The Purpose of Trade Agreements."NBER Working Paper No. 22070, page 13, footnote 12. Abba Lerner showed the possibility in his 1936 article. 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. *According to Gene Grossman, a Lerner paradox occurs when the government spends most of its tariff revenue to purchase the import good. *According to Pan-Long Tsai, a Lerner paradox occurs when the elasticity of the tariff-imposing country's import demand function is smaller than the government's spending share of its tariff r ...

Economics
Economics () is the social science that studies the Production (economics), production, distribution (economics), distribution, and Consumption (economics), consumption of goods and services. Economics focuses on the behaviour and interactions of Agent (economics), economic agents and how economy, economies work. Microeconomics analyzes what's viewed as basic elements in the economy, including individual agents and market (economics), markets, their interactions, and the outcomes of interactions. Individual agents may include, for example, households, firms, buyers, and sellers. Macroeconomics analyzes the economy as a system where production, consumption, saving, and investment interact, and factors affecting it: employment of the resources of labour, capital, and land, currency inflation, economic growth, and public policies that have impact on glossary of economics, these elements. Other broad distinctions within economics include those between positive economics, desc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tariffs
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. Tariffs can be fixed (a constant sum per unit of imported goods or a percentage of the price) or variable (the amount varies according to the price). Taxing imports means people are less likely to buy them as they become more expensive. The intention is that they buy local products instead, boosting their country's economy. Tariffs therefore provide an incentive to develop production and replace imports with domestic products. Tariffs are meant to reduce pressure from foreign competition and reduce the ...

International Trade Theory
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. Adam Smith's model Adam Smith describes trade taking place as a result of countries having absolute advantage in production of particular goods, relative to each other. Within Adam Smith's framework, absolute advantage refers to the instance where one country can produce a unit of a good with less labor than another country. In Book IV of his major work '' the Wealth of Nations'', Adam Smith, discussing gains from trade, provides a literary model for absolute advantage based upon the example of growing grapes from Scotland. He makes the argument that while it is possible to grow grapes and produce wine in Scotland, the investment in th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lerner Symmetry Theorem
The Lerner symmetry theorem is a result used in international trade theory, which states that an ad valorem import tariff (a percentage of value or an amount per unit) 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 (ad valorem tariffs or export taxes) is applied. The theorem was developed by economist Abba P. Lerner in 1936.Jagdish N. Bhagwati, Arvind Panagariya, and T. N. Srinivasan T. N. Srinivasan, in full Thirukodikaval Nilakanta Srinivasan (27 March 1933 – 11 November 2018), was an Indian economist who had taught and worked in the United States.

General Equilibrium Theory
In economics, general equilibrium theory attempts to explain the behavior of supply, demand, and prices in a whole economy with several or many interacting markets, by seeking to prove that the interaction of demand and supply will result in an overall general equilibrium. General equilibrium theory contrasts to the theory of ''partial'' equilibrium, which analyzes a specific part of an economy while its other factors are held constant. In general equilibrium, constant influences are considered to be noneconomic, therefore, resulting beyond the natural scope of economic analysis. The noneconomic influences is possible to be non-constant when the economic variables change, and the prediction accuracy may depend on the independence of the economic factors. General equilibrium theory both studies economies using the model of equilibrium pricing and seeks to determine in which circumstances the assumptions of general equilibrium will hold. The theory dates to the 1870s, particularly t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Metzler Paradox
In economics, the Metzler paradox (named after the American economist Lloyd Metzler) 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. The strange result could occur if the exporting country's offer curve In economics and particularly in international trade, an offer curve shows the quantity of one type of product that an agent will export ("offer") for each quantity of another type of product that it imports. The offer curve was first derived by ... is very inelastic. In this case, the tariff lowers the duty-free cost of the price of the import by such a great degree that the effect of the improvement of the tariff-imposing countries' terms of trade on relative prices exceeds the ...

Demand Function
In economics, a demand curve is a graph depicting the relationship between the price of a certain commodity (the ''y''-axis) and the quantity of that commodity that is demanded at that price (the ''x''-axis). Demand curves can be used either for the price-quantity relationship for an individual consumer (an individual demand curve), or for all consumers in a particular market (a market demand curve). It is generally assumed that demand curves slope down, as shown in the adjacent image. This is because of the law of demand: for most goods, the quantity demanded falls if the price rises. Certain unusual situations do not follow this law. These include Veblen goods, Giffen goods, and speculative bubbles where buyers are attracted to a commodity if its price rises. Demand curves are used to estimate behaviour in competitive markets and are often combined with supply curves to find the equilibrium price (the price at which sellers together are willing to sell the same amount as buy ...

Elasticity (economics)
In economics, elasticity measures the percentage change of one economic variable in response to a percentage change in another. If the price elasticity of the demand of something is -2, a 10% increase in price causes the demand quantity to fall by 20%. Introduction Elasticity is an important concept in neoclassical economic theory, and enables in the understanding of various economic concepts, such as the incidence of indirect taxation, marginal concepts relating to the theory of the firm, distribution of wealth, and different types of goods relating to the theory of consumer choice. An understanding of elasticity is also important when discussing welfare distribution, in particular consumer surplus, producer surplus, or government surplus. Elasticity is present throughout many economic theories, with the concept of elasticity appearing in several main indicators. These include price elasticity of demand, price elasticity of supply, income elasticity of demand, elastici ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
