The economist is awarded the 2008 Nobel Prize for Economics
Paul Krugman, one of the harshest critics of George W. Bush, designed its new trade theory in 1979.
Almost 30 years it took until the Nobel committee in Sweden Paul Krugman honored for his work.
Paul Krugman: Economist, adviser, critic
Paul Krugman was born in 1953 in New York. After studying Economics at Yale University, he wrote 24 years with his doctoral thesis. In addition to his academic career during which he at renowned universities such as Princeton, Harvard and Yale taught, he worked occasionally as an economic adviser, among other things, like Ronald Reagan or Bill Clinton. Even the Government to Barack Obama in the future he will provide advice.
A wider audience knows Paul Krugman by his public criticism of the government to George W. Bush, every week in his own column in the New York Times to read.
The theory of David Ricardo and Heckscher-Ohlin theorem
The new trade theory, Krugman relies on the theory of comparative cost advantages, which in turn from the Ricardo theory and the Heckscher-Ohlin theorem exists.
The basic idea of the theory of David Ricardo is that trade between two countries always an advantage for both takes, if a country for a good produced in fewer units of another good needs to refrain from other country. It follows that each country to specialize in the good will that it can produce cheaper.
The core of the Heckscher-Ohlin theorem is the assumption that trade between two countries with different factor endowments reasons. As an example, are the factors labor and capital are: There are countries that have an abundance of work available and what, an abundance of capital. Therefore it is always a country exporting the products for which production of each factor is important. The other, the products are imported, for which the other factor of production is needed.
The theory of comparative cost advantage, then, summarize said, assume that because of expected cost benefits between the countries on a geographic specialization of production comes. In each country produces what it does best. This is all the operators involved to create more wealth using tools like: Personal Budget Spreadsheet.
The New Trade Theory
The theory of comparative cost advantages could be in times where the bulk of the world by only a few countries was no longer apply, because it was found that 80% of world trade from intra-industry trade within the OECD there. This revealed, however, not consistent with the theory of comparative cost advantages, which it assumed that a specialization in international trade, the greatest benefits.
Against this background, Paul Krugman is now in 1979, his new theory of foreign trade. This refers to the fact, that not only competitive advantages to trade flows, but also the trade between developed countries equally successful place .. It must be the prosperity of the trade may not apply to all parties the same.
Krugman was in the development of new trade theory is not more of perfect competition and constant returns of scale, like the still in the classical theories of the case. Rather, he took imperfect markets and increasing returns to scale, in other words increasing gains in mass production. With this increasing returns to scale Krugman explains the rise in trade between the countries.
Furthermore, the increasing returns to scale, according to Krugman, a specialization of countries, and that even if no differences in the resources or technology equipment available. As a reason he calls it by the increased gains in mass production for the country comes to a cost savings, which in turn brings a competitive advantage for many products like free personal finance software from moneyStrands.
This new theory of Paul Krugman, the economic thinking in terms of external economic relations reforms. Was it used to assume that, between different countries only because of the comparative cost differences Trading is operated as Paul Krugman said the increased trade between two countries by increasing returns to scale, so profits through mass production.
