Since the beginning of the 90's the New Economic Geography (NEG) has been a theoretical reference for several researches on regional and urban economics. The main task of this paper is to present a critical assessment of the NEG approach, which has in the book The Spatial Economy, by M.Fujita,...

"The Spatial Economy Cities, Regions and International Trade", by Masahisa Fujita, Paul Krugman and Anthony J. Venables, has been seen as the best synthesis of the so-called new economic geography. The purpose of this paper is twofold: first, to review the book; and second, to place it in the...

This paper analyses the methodology developed by Behrens and Murata (2007) to introduce variable mark-ups into models of monopolistic competition. Their risk- aversion explanation to the presence of ¯xed mark-ups in the Dixit and Stiglitz (1977) model is validated; however, we show that their...

This paper examines the agglomeration benefits of a transportation improvement in a city by modeling the microstructure of urban agglomeration based on monopolistic competition of differentiated intermediate products. Properly extended to include variety distortion in addition to price...

During the 19th century, the Spanish economy went through the early stages of the industrialisation process. This process developed in parallel to the growing market integration of goods and factors as a result of the liberal reforms and the construction of the railway network, with the...

The project studies the Krugman's CP model in the weakly explored case of asymmetric regions in two settings: international trade and agglomeration processes. First setting implies that the industrial labor is immobile, while second one consider mobile industrial labor and long-run equilibria....

We study multiregional extension of Krugman's Core-Periphery model. Comprehensive characterization of agglomeration stability is obtained in terms of the basic parameters of model. In particular, conditions of uniqueness of the stable total agglomerated equilibrium were obtained. The main...
