A robust prediction across a wide range of open-economy macroeconomic models is that an unanticipated increase in public spending in a given country appreciates it currency in real terms. This result, however, contradicts the findings of a number of recent empirical studies, which instead...

Based on recent data concerning the French distribution networks in retail and services, this paper highlights several stylized facts relating to the sector-based differences in the organizational choices. Until now this issue has not been studied in the economical literature. This paper...

This article reveals and studies the connections between Bentham’s Defence of Usury (1787) and Saint-Amand Bazard (1791-1832), a founder of Saint-Simonianism. We first traces Bazard’s exposure to Bentham through his unknown friendship with Bentham’s publisher Etienne Dumont. After...

This paper focuses on residential sorting by social and ethnic status in large French urban areas. Our objective is to assess the relative importance of two major determinants of segregation stressed by the economic literature (Bartolome and Ross, 2003 ; Brueckner et al., 1999) : (i) “Alonso...

This paper examines if taking into account changes in the number of producers, or equivalently changes in the product variety space over the business cycle, helps to understand and replicate international business cycle facts. To this end, we develop a two-country model in which the economy is...

We use skin conductance responses and self-reports of hedonic valence to study the emotional basis of cooperation and punishment in a social dilemma. Emotional reaction to free-riding incites individuals to apply sanctions when they are available. The application of sanctions activates a...

This paper analyzes jointly optimal fiscal and monetary policies in a small open economy with capital and sticky prices. We allow for trade in consumption goods under perfect international risk sharing. We consider balanced-budget fiscal policies where authorities use distortionary taxes on...

In this paper we examine the role played by heterogeneity in the popular “connections model” of Jackson and Wolinsky (1996). We prove that under heterogeneity in values or decay involving only two degrees of freedom, all networks can supported as Nash. Moreover, we show that Nash networks...

In this paper, we pursue the work of H. Haller and al. (2005, [10]) and examine the existence of equilibrium networks, called Nash networks, in the noncooperative two-way flow model (Bala and Goyal, 2000, [1]) with partner heterogeneous agents. We show through an example that Nash networks do...

This paper introduces a partner heterogeneity assumption in the one-way flow model of Bala and Goyal (2000, [1]). Our goal consists in the characterization of strict Nash networks with regard to the set of resources obtained by players. We use the notion of condensation network which allows us...
