So, geographically where can manufacturing be predicted to develop? Krugman states that manufacturing's geographical range is inherently limited by economies of scale, but also that manufacturing will establish and accrue itself in an area of high demand. Production that occurs adjacent to demand will result in lower transportation costs, but demand, as a result, will be greater due to concentrated nearby production. These forces act upon one another simultaneously, producing manufacturing and population agglomeration. Population will increase in these areas due to the more highly developed infrastructure and nearby production, therefore lowering the expense of good, while economies of scale provide varied choices of goods and services. These forces will feed into each other until the greater portion movie of the urban population and manufacturing hubs are concentrated into a relatively insular geographic area. 45 International finance Krugman has also been influential in the field of international finance. As a graduate student, Krugman visited the federal Reserve board, where Stephen Salant and Dale henderson were completing their discussion paper on speculative attacks in the gold market.
37 Nonetheless, trade remains beneficial in general, even between similar countries, because it permits firms to save on costs by producing at a larger, more efficient scale, and because it increases the range of brands available and sharpens the competition between firms. 38 Krugman has usually been supportive of free trade and globalization. 39 40 he has also been critical of industrial policy, which New Trade Theory suggests might offer nations rent-seeking advantages if "strategic industries" can be identified, essay saying it's not clear that such identification can be done accurately enough to matter. 41 New economic geography It took an interval of eleven years, but ultimately Krugman's work on New Trade Theory (NTT) converged to what is usually called the "new economic geography" (neg which Krugman began to develop in a seminal 1991 paper, "Increasing Returns and Economic. 42 In Krugman's own words, the passage from ntt to neg was "obvious in retrospect; but it certainly took me a while to see. The only good news was that nobody else picked up that 100 bill lying on the sidewalk in the interim." 43 This would become Krugman's most-cited academic paper: by early 2009, it had 857 citations, more than double his second-ranked paper. 31 Krugman called the paper "the love of my life in academic work." 44 The "home market effect" that Krugman discovered in ntt also features in neg, which interprets agglomeration "as the outcome of the interaction of increasing returns, trade costs and factor price differences.". That is, ntt implies that instead of spreading out evenly around the world, production will tend to concentrate in a few countries, regions, or cities, which will become densely populated but will also have higher levels of income. 10 Agglomeration and economies of scale manufacturing is characterized by increasing returns to scale and less restrictive and expansive land qualifications as compared to agricultural uses.
Krugman modeled a 'preference for diversity' by assuming a ces utility function like that in a 1977 paper by avinash Dixit and Joseph Stiglitz. 33 34 Many models of international trade now follow Krugman's lead, incorporating economies of scale in production and a preference for diversity in consumption. 35 This way of modeling trade has come to be called New Trade Theory. 31 Krugman's theory also took into account transportation costs, a key feature in producing the " home market effect which would later feature in his work on the new economic geography. The home market effect "states that, ceteris paribus, the country with the larger demand for a good shall, at equilibrium, produce a more than proportionate share of that good and be a net exporter." 31 The home market effect was an unexpected result. 31 When there are economies of scale in production, it is possible that countries may become ' locked into ' disadvantageous patterns of trade. 36 Krugman points out that although globalization has been positive on a whole, since the 1980s the process known as hyper-globalization has at least played a part in rising inequality.

The importance of spatial issues in economics has been enhanced by Krugman's ability to popularize this complicated theory with the help of easy-to-read books and state-of-the-art syntheses. "Krugman was beyond doubt the key player in 'placing geographical analysis squarely in the economic mainstream'. And in conferring it the central role it now assumes." 31 New trade theory Prior to Krugman's work, trade theory (see david Ricardo and HeckscherOhlin model ) emphasized trade based on the comparative advantage of countries with very moment different characteristics, such as a country with. However, in the 20th century, an ever-larger share of trade occurred between countries with similar characteristics, which is difficult to explain by comparative advantage. Krugman's explanation of trade between similar countries was proposed in a 1979 paper in the journal of International Economics, and involves two key assumptions: that consumers prefer a diverse choice of brands, and that production favors economies of scale.
32 Consumers' preference for diversity explains the survival of different versions of cars like volvo and bmw. However, because of economies of scale, it is not profitable to spread the production of Volvos all over the world; instead, it is concentrated in a few factories and therefore in a few countries (or maybe just one). This logic explains how each country may specialize in producing a few brands of any given type of product, instead of specializing in different types of products.

Solid lines denote stable equilibria, dashed lines denote unstable equilibria.

Since present-day science fell far short of "psychohistory krugman turned to economics as the next best thing. 19 20 Krugman earned his. 21 summa cum laude in economics from Yale University in 1974, and went on to pursue a phD in economics from Massachusetts Institute of Technology (MIT). In 1977, he successfully completed his PhD in three years, with a thesis titled Essays on flexible exchange rates. While at mit, he was part of a small group of mit students sent to work for the central Bank of Portugal for three months in the summer of 1976, during the chaotic aftermath of the carnation revolution. 22 Krugman later praised resume his PhD thesis advisor, rudi dornbusch, as "one of the great economics teachers of all time" and said that he "had the knack of inspiring students to pick up his enthusiasm and technique, but find their own paths". 23 In 1978, Krugman presented a number of ideas to dornbusch, who flagged as interesting the idea of a monopolistically competitive trade model.
