Aging nations and the future of cities Inra
Gaigné, C.; Thisse, J.F.; INRA, Institut National de la Recherche Agronomique (FRA).
We investigate whether an aging population may challenge the supremacy of large working cities. To this end, we develop an economic geography model with two types of individuals (workers and retirees) and two sectors (local services and manufacturing). Workers produce and consume; the elderly consume only. As a result, the mobility decision of workers is driven by both the wage gap and the cost-of-living gap, unlike the elderly who react to the differences in the cost of living only. We show that the return of pre-industrial urban system dominated by rentier cities does not seem to be on the agenda. Quite the opposite, the future of large working cities is still bright, the reason being that today's urban costs act as a strong force that prevents a large...

Are compact cities environmentally friendly? Inra
Gaigné, C.; Riou, S.; Thisse, J.F.; INRA, Institut National de la Recherche Agronomique (FRA).
There is a large consensus among international institutions and national governments to favor urban-containment policies –the compact city– as a way to improve the ecological performance of the urban system. This approach overlooks a fundamental fact: what matters for the ecological outcome of cities is the mix between the level of population density and the global pattern of activities. As expected, when both the intercity and intra-urban distributions of activities are given, a higher population density makes cities more environmentally friendly. However, once we account for the fact that cities may be either monocentric or polycentric as well as for the possible relocation of activities between cities, the relationship between population density and the...

Trade and the structure of cities Inra
Cavailhes, J.; Gaigné, C.; Tabuchi, T.; Thisse, J.F..
Our purpose is to investigate how the interplay between trade, commuting and communication costs shapes the economy at both the interregional and intra-urban levels. Specifically, we study how economic integration affects the internal structure of cities and show how decentralizing the production and consumption of goods in secondary employment centers allows firms located in a large city to maintain their predominance. Several new results in both economic geography and urban economics are established, which all agree with empirical evidence.
