Krugman's Model with Various Values of the Costs of Transport -under Maple Software

Florin Dan Puscaciu, Rose-Marie Puscaciu


The centrum-peripherical model due to Paul Krugman (1991) with all its merits for
grounding the economics crowdings, also scored the appearance of a new field in the economic
theory, known as “The New Economic Geography”. There were some criticism which were focused
on this matter, such as the simetry of the transport costs for the industrial goods, and the ignoring the
transport costs for the agricultural goods. These criticisms could be evaded by improving the model,
so as this work tries to do. On the other hand, the achieving of a computational programme is very
useful in numerical simulations, necessary for studying the model, taking into account that the model
can not be analytically solved.
