Popper a rompu avec une tradition épistémologique ancienne en introduisant une dissymétrie entre vérifiabilité et réfutation. Cette conception a d'importantes répercussions sur la manière d'envisager la croissance des connaissances scientifiques et l'activité du chercheur. La vérité,...

This article critically examines the EU ETS intertemporal market during its Phase I (2005-2007). We test the Hotelling rule as a key element of a competitive equilibrium to validate whether allowance prices rise at the same rate as the interest rate. Including readily observable characteristics...

The current financial crisis has now led most major central banks to rely covertly or overtly on quantitative easing. The unique Japanese experience of quantitative easing is the only experience which enables us to judge this therapy's effectiveness and the timing of the exit strategy. This...

Rarement une contribution théorique, formulée dans un cadre mathématique original, a eu autant d'influence sur le développement de l'analyse économique et de certaines de ses applications - notamment en assurance et en finance - que le modèle de von Neumann-Morgenstern de choix...

This paper explores the evolution of OECD imports over time and as a function of income levels, measuring the concentration of those imports across origin countries at the product level. We find evidence of diversification followed, in the very last years of the sample period (post-2000), by a...

We study a unidimensional model of spatial competition between two parties with two types of politicians. The office oriented politicians, referred to as “opportunist” politicians, care only about the spoils of the office. The policy oriented politicians, referred to as “militant”...

Arthur Charpentier (see Arthur's blog) was recently contacted by some researchers willing to test if a multivariate copula is - or not - Gaussian. They use a test proposed in Malevergne and Sornette (2003) stating that one should simply test for pairwise normality. This test may be of importance...

We use a 3-step analysis to assess the sustainability of public finances in the EU27. Firstly, we perform the SURADF specific panel unit root test to investigate the meanreverting behaviour of general government expenditures and revenues ratios. Secondly, we apply the bootstrap panel...

La gestion des prélèvements d'organes est souvent considérée, dans la littérature scientifique, comme une illustration d'un système fondé sur le don. Toutefois, le système français de transfert des organes est un ensemble complexe de règles d'organisation, dont les fondements...

We use household survey data and a unique census of institutionalized children to analyze the impact of abortion legalization in Romania. More exactly, we exploit the lift of the abortion ban in December 1989, when communist dictator Ceausescu and his regime were removed from power, to...
