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

The centrum-peripherical model due to Paul Krugman (1991) with all its merits forgrounding the economics crowdings, also scored the appearance of a new field in the economictheory, known as “The New Economic Geography”. There were some criticism which were focusedon this matter, such as the simetry of the transport costs for the industrial goods, and the ignoring thetransport 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 veryuseful in numerical simulations, necessary for studying the model, taking into account that the modelcan not be analytically solved.
