Mardi | 2009-12-01 Nicolas DEBARSY – Vincenzo VERARDI – Amine LAHIANI In spatial autoregressive models, the functional form of autocorrelationis assumed to be linear. In this paper, we propose a simple semiparametricprocedure, based on Yatchew’s (1997) partial linear least squares, that doesnot impose this restriction. Simple simulations show that this model outper-forms traditional SAR estimation when nonlinearities are present. We thenapply the methodology on real data to test for the spatial pattern of vot-ing for independent candidates in US presidential […]

Mardi | 2009-11-24 Thierry MONTALIEU – Isabelle RABAUD – Thierry BAUDASSE Theoretically, welfare gains from liberalisation of trade in services arise from falling pricesand technology transfers from foreign firms. Empirically, substantial gains are only reachedwhen entry of foreign firms is widened. These results rest upon three strong assumptions.First, substitution elasticities need to be important, which is not the case empirically foraggregated service data. Second, information is required on the breakdown of the initial pricewedgebetween rent and inefficient technology. Third, wage […]

GERGAUD – Vincenzo VERARDI – Cyrille PIATECKI When studying the problem of the emergence of superstars, scholars face dif-…culties in measuring talent, obtaining con…dential data on earnings, and …ndingeconometric techniques that are robust to the presence of outliers (superstars).In this paper we use a quasi-experimental dataset from the Pokemon trading cardgame in which (i) there is no unidenti…able heterogeneity, (ii) rarity can be sepa-rated from talent and (iii) objective earnings are observable through transactionprices. Using semi-parametric […]

Mardi | 2009-10-13 Rémi BAZILLIER – Yasser Moullan – Thierry BAUDASSE We study in this paper the interactions between migration rates and the level of labourstandards. We use an augmented version of the Grogger and Hanson (2008) model, addingthe level of working conditions into the specification. Our hypothesis is that the differentialof working conditions may be a complementary determinant of migration. In a first time, wetest the influence of labour standards in countries of origin using a database on emigrationrates […]
