Krugman defined the New Economic Geography as the location theory of production, just as the concept of the classical location theory, which is proposed to explain the mechanism of formation and evolution of the economic spatial structure. The New Economic Geography theory of Krugman, scattered in his several books, is summed up as follows: a main idea, four propositions, four tools and three models. In order to analyze more clearly the process of formation and evolution of economic spatial structure, Krugman puts forward four propositions: 1 Transportation Costs play a key role in international trade and inter-regional trade; 2 Spatial agglomeration of interrelated economic activity could achieve cost-saving and benefit-increasing; 3 The cost-saving and benefit-increasing from the economic spatial agglomeration could promote the further concentration of economic development; 4 Early-development advantage could lead to the long-term accumulation of economic activity.

Farmanesh, Amir : Regional dimensions of economic development in Iran: A new economic geography approach. This paper presents a spatial analysis of the regional dimensions of poverty and economic development across provinces of Iran. It offers one of the few estimations made in developing countries using this strand of New Economic Geography NEG models and provides a comparison of the results for Iran with those in previously studied developed countries. The goal of this study is to offer an analysis of the effects of agglomeration and dispersion economies on the patterns of regional economic development in Iran based on the empirical estimation of two of the NEG models. First, it presents an estimation of a Market Potential Function MPF , in which wages are associated with proximity to consumer markets. Second, it estimates an augmented MPF derived from the Krugman model of economic geography that estimates the importance of transportation costs and economies of scale. The estimation results suggest that Iran shows a generally good fit to both models, satisfying their specifications.

Paul Krugman: contributions to Geography and Trade

This work consists of a survey of the academic work of Paul Robin Krugman. It seeks to shed light on his main contributions to economic theory, mainly those for which he was awarded the Nobel Prize in Economics in His legacy in academia can be assessed through the recognition of his work on the identification of international trade patterns and the explanation on why spatial imbalances in the distribution of economic activities arise in an increasingly globalized economy. Through these contributions to trade theory and economic geography, Krugman is often credited as being one of the pioneering researchers in the New Trade Theory and the founding father together with Masahisa Fujita of the New Economic Geography.

Prior to that, Fujita and Ogawa studied multiple urban structures in a model with positive inter-firm spillovers.

The Nobel prize for economics was awarded to Paul Krugman for three papers -Krugman , , In this paper we illustrate that, indeed, these three papers are closely connected. We present - a summary of - the papers using a unified framework. Central in the discussion is the so-called home market effect that was already alluded to in Krugman We evaluate his work and conclude that these three papers changed and improved the way economists think about trade and geography.

Geography and Trade

It is argued that the extension of trade theory to geographical economics has widened the scope of analysis of economic interaction between different countries or regions , but that the NEG still has some way to go in exploring the role of space. Transport costs have mostly been introduced in an ad-hoc fashion, but there are first attempts to endogenize them in terms of market prices for trade services. The location of production The producing unit with the lowest costs requires production at a large scale and distribution of the products of a corresponding area. For these two reasons, division of labour will take place between different areas, since different industries are concentrated in different areas.

Over the centuries, international trade and the location of economic activity have been at the forefront of economic thought. Even today, free trade, globalization, and urbanization remain as commonplace topics in the popular debate as well as in scholarly analyses. Traditionally, trade theory and economic geography evolved as separate subfields of economics. More recently, however, they have converged become more and more united through new theoretical insights, which emphasize that the same basic forces simultaneously determine specialization across countries for a given international distribution of factors of production trade theory and the long-run location of those factors across countries economic geography.

On October 13 th , the Nobel Prize for economics was awarded to Paul Krugman for his work on trade and geography. In its scientific background report the Royal Swedish Academy of Sciences motivated the choice to award the Nobel Prize to Krugman as follows p. The committee stresses that the award was essentially given to Krugman for three of his papers: Krugman , , a, see the list of references in our book. The paper sets out the core model of geographical economics and is thus the main building block for chapters 3 and 4 of our book.

Economic geography is the subfield of human geography which studies economic activity. It can also be considered a subfield or method in economics. Economic geography takes a variety of approaches to many different topics, including the location of industries, economies of agglomeration also known as "linkages" , transportation , international trade , development, real estate , gentrification , ethnic economies, gendered economies, core-periphery theory, the economics of urban form , the relationship between the environment and the economy tying into a long history of geographers studying culture-environment interaction , and globalization.

Geography and trade : by Paul Krugman, Cambridge: The MIT Press, 1991, pp xi + 142

From Gaston Eyskens Lectures. Krugman observes that his own shortcomings in ignoring economic geography have been shared by many professional economists, primarily because of the lack of explanatory models. In Geography and Trade he provides a stimulating synthesis of ideas in the literature and describes new models for implementing a study of economic geography that could change the nature of the field. Economic theory usually assumes away distance. Krugman argues that it is time to put it back - that the location of production in space is a key issue both within and between nations. John Sutton.

Я считываю их с вашего компьютера. Стратмор недоверчиво покачал головой. - Ты пробрался в мой кабинет. - Нет. Я сделал это, не выходя из Третьего узла.

Фил физически ощущал, что времени остается все меньше. Он знал: все уверены, что он ушел. В шуме, доносившемся из-под пола шифровалки, в его голове звучал девиз лаборатории систем безопасности: Действуй, объясняться будешь. В мире высоких ставок, в котором от компьютерной безопасности зависело слишком многое, минуты зачастую означали спасение системы или ее гибель. Трудно было найти время для предварительного обоснования защитных мер. Сотрудникам службы безопасности платили за их техническое мастерство… а также за чутье.

Она старательно расшифровывала текст, завороженная тем, как на первый взгляд произвольный набор цифр превращался в красивые стихи. В тот момент она поняла, что нашла свою любовь - шифры и криптография отныне станут делом ее жизни. Почти через двадцать лет, получив степень магистра математики в Университете Джонса Хопкинса и окончив аспирантуру по теории чисел со стипендией Массачусетского технологического института, она представила докторскую диссертацию- Криптографические методы, протоколы и алгоритмы ручного шифрования. По-видимому, ее работу прочел не только научный руководитель, потому что вскоре последовал телефонный звонок, а затем по почте ей доставили авиационный билет от АНБ. Все, кто имел отношение к криптографии, знали, что о АНБ собраны лучшие криптографические умы нашей планеты.

Сердце ее заколотилось. Затаив дыхание, она вглядывалась в экран. КОД ОШИБКИ 22 Сьюзан вздохнула с облегчением. Это была хорошая весть: проверка показала код ошибки, и это означало, что Следопыт исправен.

Теоретически постоянная мутация такого рода должна привести к тому, что компьютер, атакующий шифр, никогда не найдет узнаваемое словосочетание и не поймет, нашел ли он искомый ключ. Вся эта концепция чем-то напоминала идею колонизации Марса - на интеллектуальном уровне вполне осуществимую, но в настоящее время выходящую за границы человеческих возможностей. - Откуда вы взяли этот файл? - спросила .

 Наверное, хотел сюда переехать, - сухо предположил Беккер. - Да. Первая неделя оказалась последней.

Расскажи это Чатрукьяну. Стратмор подошел ближе.

Девушка высвободилась из его рук, и тут он снова увидел ее локоть. Она проследила за его взглядом, прикованным к синеватой сыпи. - Ужас, правда. Беккер кивнул.

 - Первым делом вы отдаете мне пистолет. И оба идете со. - В качестве заложников? - холодно усмехнулся Стратмор.

Чатрукьян заколебался. - Я не могу. - Разумеется, не можете. Его же не существует.

Обе хорошенькие. Сердце Беккера подпрыгнуло.

Думаю, англичанка. И с какими-то дикими волосами - красно-бело-синими. Беккер усмехнулся, представив это зрелище.

Мы можем восстановить его репутацию. Мы должны пойти на. - Слишком поздно, - сказал Стратмор.
