La position de la France dans l'industrie européenne des machines à vapeur durant la seconde moitié du XIXe siècle∗

At least from the standpoint of the steam‐engine industry, the nature of industrial relations between France and other countries underwent a significant change during the half century which elapsed between 1860 and 1910. Towards 1860, the major characteristics are dispersion and nationalism; on the other hand, at the beginning of the twentieth century, while there is a new concentration on the national level, it confronts a distinct cosmopolitanism on the international level. To give an idea of this evolution, we will refer to two French works on steam‐engines, dated 1861–62 and 1913 respectively. They are of an essential practical nature and describe a large number of engines which were actually available on the market. Below, we will successively examine the early manufacturers existing through 1861–62, then those dating from 1913 only, and finally the establishments which have endured throughout the whole period under consideration. This study aims at pointing out the clear decadence of the French industry which became increasingly dependent upon foreign sources in the areas of technical creativeness as well as production.     

TOWARD A UNIFIED THEORY OF ECONOMIC GEOGRAPHY AND URBAN ECONOMICS*

ABSTRACT In this paper, I pursue two objectives. First, I propose a primer in economic geography relying on a simple model that can be solved analytically by undergraduate students. Second, I briefly discuss two topics that, in my opinion, should rank high on the research agenda.     

AGING NATIONS AND THE FUTURE OF CITIES*

ABSTRACT 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 share of local services and manufacturing firms from following the rentiers in the elderly cities, while the supply of differentiated b2c services impede their complete separation.
