Military Expenditure and Economic Growth Literature: A Meta-Analysis

[eng] Transportation costs and monopoly location in presence of regional disparities. . This article aims at analysing the impact of the level of transportation costs on the location choice of a monopolist. We consider two asymmetric regions. The heterogeneity of space lies in both regional incomes and population sizes: the first region is endowed with wide income spreads allocated among few consumers whereas the second one is highly populated however not as wealthy. Among the results, we show that a low transportation costs induces the firm to exploit size effects through locating in the most populated region. Moreover, a small transport cost decrease may induce a net welfare loss, thus allowing for regional development policies which do not rely on inter-regional transportation infrastructures. cost decrease may induce a net welfare loss, thus allowing for regional development policies which do not rely on inter-regional transportation infrastructures. [fre] Cet article dveloppe une statique comparative de l’impact de diffrents scnarios d’investissement (projet d’infrastructure conduisant une baisse modre ou une forte baisse du cot de transport inter-rgional) sur le choix de localisation d’une entreprise en situation de monopole, au sein d’un espace intgr compos de deux rgions aux populations et revenus htrognes. La premire rgion, faiblement peuple, prsente de fortes disparits de revenus, tandis que la seconde, plus homogne en termes de revenu, reprsente un march potentiel plus tendu. On montre que l’htrognit des revenus constitue la force dominante du modle lorsque le scnario d’investissement privilgi par les politiques publiques conduit des gains substantiels du point de vue du cot de transport entre les deux rgions. L’effet de richesse, lorsqu’il est associ une forte disparit des revenus, n’incite pas l’entreprise exploiter son pouvoir de march au dtriment de la rgion
