The health cost of living in a city: The case of France at the end of the 19th century

Despite a long standing debate over urban living conditions during industrialization, the impact of rural–urban migrations on health and mortality remains an open question. We observe both mortality and geographical mobility in a large longitudinal dataset of French males and show that rural–urban migrants benefited from clear advantages over those who already lived in the city. However, this benefit fades in a few years. Further we find no evidence of a spike in mortality among rural migrants as they encountered the more severe disease environment of cities, instead it seems their initially superior physical human capital was depleted over time.     

Relational Goods and Associational Participation

Abstract *** :  In this paper, we focus on the role of interpersonal contact and the possibility of a relational motive to explain participation and volunteering in associations. Drawing on the relational goods theory, we show that associational activities are favorable to production and consumption of such goods. So, associational participants are expected to have more personal interactions. This theoretical hypothesis is tested using a cross‐sectional data set conducted in France in 1999. Our econometric analysis, which controls for endogeneity of associational participation using a simultaneous equations model, emphasizes a significantly positive relationship between this participation and preferences for relational goods .     

The U-Shaped Productivity Dynamics of French Exporters

We use data on French manufacturing firms to reveal that the productivity dynamics of new exporters is typically U-shaped. Prior to entry, firm productivity temporarily decreases, then recovers contemporaneously with entry, as the benefits from sales to foreign markets accrue. We show that the U-shaped pattern is more pronounced for intensively exporting firms and for firms operating in capital-intensive or high-technology sectors. This finding suggests that firms prepare to become exporters through prior specific investments and learning-to-export mechanisms. We then point to the limitations of studies that focus only on date of entry to exporting to discriminate between self-selection versus learning mechanisms. JEL no.  F10, F14, L60

When Does the Stepping‐Stone Work? Fixed‐Term Contracts Versus Temporary Agency Work in Changing Economic Conditions

This paper emphasizes differences among short‐term contracts in terms of career prospects. Using French data over the 2002–2010 period, we rely on a dynamic model with fixed effects to disentangle state dependence from unobserved heterogeneity. Although fixed‐term contracts may provide a ‘stepping‐stone’ to permanent positions, temporary agency work is hardly better than unemployment in this regard. The Great Recession of 2008 has changed the dynamics on the labor market and amplified the difference between fixed‐term contracts and temporary agency work. For both types of temporary workers, providing overtime work does not significantly increase the transition to permanent employment. Copyright © 2014 John Wiley & Sons, Ltd.     

Intergenerational Wealth Mobility in France, 19th and 20th Century

This paper examines intergenerational wealth mobility between fathers and children in France between 1848 and 1960. Considering wealth mobility in the long run requires taking into account not only positional mobility (that is, how families move within a given distribution of wealth), but also structural mobility induced by changes in the distribution of wealth. Such changes are related to two structural phenomena: in the nineteenth century, the rising number of individuals leaving no estate at death and, after World War I, the decline in the number of the very rich who could live off their wealth. The paper studies the movements between these groups and estimates the intergenerational elasticity of wealth, taking into account the persistence at the bottom and at the top.
