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...

Countries, regions and trade: on the welfare impacts of economic integration Inra
Behrens, K.; Gaigne, C.; Ottaviano, G.I.P.; Thisse, J.F..
We study the impact of falling international trade costs and falling national transport costs on the economic geography of countries involved in an integration process. Each country is formed by two regions between which labor is mobile, whereas there is no international mobility. Goods can be traded both nationally and internationally at positive, but different, costs. A decrease in trade costs and/or in transport costs has a direct impact on prices and wages in both countries. This allows us to account for the impact of changes in these parameters on the economic geography and welfare of each country. We show that, as trade barriers fall, the benefits of integration come after its costs. We also show that national transport policies are of the...

Industry location and welfare when transport costs are endogenous Inra
Behrens, K.; Gaigné, C.; Thisse, J.F..
Although transport costs are a key-ingredient of New Economic Geography, the transport sector is usually abstracted away from the analysis. Put differently, freight rates are taken as parametric and are not set by the market. This paper studies the relationships between transport costs, industry location, and welfare when freight rates are set by profit-maximizing carriers. We show that the demand for transport services becomes less elastic as the degree of spatial agglomeration rises, which increases carriers' market power and allows them to charge higher markups. Once it is recognized that firms and consumers are free to relocate in response to changes in transport costs, an increasing number of carriers, falling fixed or marginal costs in...

Is remoteness a locational disadvantage? Inra
Behrens, K.; Gaigné, C.; Ottaviano, G.I.P.; Thisse, J.F.; INRA, Institut National de la Recherche Agronomique (FRA).
We study the impacts of changes in international trade and domestic transport costs on the internal geography of countries in the presence of geographical asymmetries. To do so, we develop a two-country four-region model in which one country has a region that exhibits a ‘geographical advantage’ in terms of better access to the other country’s markets. Our analysis reveals that, in equilibrium, the space-economies of the trading partners are interdependent and that agglomeration in one country reduces the occurrence of agglomeration in the other, thus showing that physical geography suffices to build strong connections between the two space-economies. We also show that remoteness need not be a geographical disadvantage since a landlocked region may well be...

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.
