p-Parts of character degrees and the index of the Fitting subgroup
2014
Abstract In a solvable group G, if p 2 does not divide χ ( 1 ) for all χ ∈ Irr ( G ) , then we prove that | G : F ( G ) | p ≤ p 2 . This bound is best possible.
A Note on Symmetry in Job Contact Networks
2007
Since the seminal work of Granovetter (1995), the sociological literature highlighted the importance of social relationships, like friends, relatives and acquaintances, as sources of information on jobs in labor markets. Such importance is also confirmed by a number of empirical studies.3 More recently, economists have devoted considerable attention to this topic,4 so that the study of individual and aggregate economic outcomes produced by the presence of social relationships in labor markets is becoming a fruitful research area in economics.
Muséo-parcs et réenchantement de l’expérience muséale : le cas de la Cité des Arts et des Sciences de Valencia
2010
The museum offer undergoes at present profound transformations. Beyond the traditional structures which do not any more hesitate to use innovative museographies and to slide in the sphere of the leisure activities, it seems to develop a new sector, halfway between museums and amusement parks called museopark. The aim of this article is to analyze an example of this hybrid offer, the City of Arts and Science in Valencia (Spain), fitting very well with the edutainment logic and to understand the structuring elements and the borrowings made in of the amusement parks. After the presentation of theoretical foundations underlying the definition of experiential museums, we expose our case study, b…
Does the GATT/WTO promote trade? After all, Rose was right
2019
This paper re-examines the effect of the GATT/WTO on trade using recent econometric developments that allow us estimating structural gravity equations with the Poisson pseudo-maximum likelihood (PPML) estimator on a large dataset that requires computing high-dimensional fixed effects. By doing so, we overcome computational limitations that are present in previous studies. In line with Rose’s (Am Econ Rev 94:98–114, 2004) seminal work, we find that, unlike regional trade agreements and currency unions, the GATT/WTO accession has not generated positive trade effects. This result is robust to the use of alternative measures of trade flows, across periods and country groups, to changes in the p…

Modeling the Probability of Informed Trading in the European Carbon Market
2012
We provide evidence of informed trading in the European carbon market. We adapt Easley et al.’s (1996) PIN methodology to the particularities of this market by isolating the trading activity on the two carbon offsets: European Union Allowances (EUAs) and Certified Emission Reductions (CERs). We find that the PIN regularly increases before the publication of the yearly verified-emission reports. CERs exhibit lower average PIN than EUAs. While the PIN of CERs has increased over time, together with its share in total trading activity, EUAs’ PIN has remained pretty stable. Our findings suggest that CERs must not be avoided in any decision or analysis made by researchers, regulators or traders i…

Going Public – Going Private: The Case of VC-Backed Firms
2012
We investigate the decisions of listed firms to go private once again. We start by revealing that while a significant number of firms which go public is VC-backed, an overproportional share of these VC-backed firms go private later on (they stay on the exchange for an average of 8.5 years). We interpret this very robust pattern such that IPOs of VC-backed firms are to a large extent a temporary rather than a permanent feature of the corporate governance of these firms.We investigate various potential hypotheses why VCs actually seem to be able to bring marginal firms to the exchange by relating the going-private decisions to various characteristics of the IPO market as well as to VC charact…
Intraday Price Dynamics between EUAs and CERs in the European Carbon Futures Market
2011
We provide the first intraday analysis on the contribution to price discovery of two emissions carbon credits: European Union Allowances (EUAs) and Certified Emission Reductions (CERs). We find that EUAs lead price discovery but CERs play a growing role and, therefore, should not be ignored.
