Brief introduction of Krugman model

Paul krugman is currently a professor of economics in the Economics Department of MIT. Krugman's main research fields include international trade, international finance, currency crisis and exchange rate change theory. The new international trade theory he founded analyzes and explains the influence of income growth and imperfect competition on international trade. His theoretical thinking is original, and he often notices important economic problems before others, and then establishes an impressive, profound, concise and elegant model for other latecomers to further study. He is regarded as one of the most outstanding trade theorists in the world today, and his prediction of the Asian financial crisis in 1994 made him famous on the international economic stage. He is currently an economic policy adviser to many countries and regions. Krugman is the inheritor and defender of the mainstream economics school, and also the favorite of Samuelson and Thoreau (they are in the same office suite). But at the same time, Krugman is also a deep-water bomb and dares to fight any traditional theory. In the past ten years, he published nearly twenty books and hundreds of articles. His writing style is clear, fluent and simple, which is not only a must-read for professional researchers, but also a mentor and friend for the general public. In the eyes of the public, he is a rare public economist.
