Intra-European Trade of Manufacturing Goods : An extension of the Gravity Model

In this paper, we propose and test several extensions of the standard gravity model. This yields a specification that allows for (i) a more flexible income response; (ii) a competitiveness effect with a general and a specific component; and (iii) an alternative and consistent measure of remoteness. Those extensions were found to be significant factors to explain intra-EU trade. Next, we analyze the effect of EU harmonization of technical regulations on domestic and intra-EU trade. We find, at different levels of aggregation of the manufacturing sector, that harmonization of regulations has contributed to more intra-EU trade but, apparently, did not affect the so called border effect.

Le prix du vin, qualité ou réputation ?

Dans ce numéro de Regards économiques, nous montrons que les différences de prix observées entre 215 vins de Bordeaux cotés dans un guide réputé dépendent davantage de l'appellation, de la réputation du producteur, du classement de 1855 que des différences en qualité ou en rareté. Même en tenant compte de tous ces effets, certains vins sont offerts sur le marché, du moins temporairement, à des prix anormalement élevés ou très agréablement bon marché.

Long-term and large-scale multispecies dataset tracking population changes of common European breeding birds

Around fifteen thousand fieldworkers annually count breeding birds using standardized protocols in 28 European countries. The observations are collected by using country-specific and standardized protocols, validated, summarized and finally used for the production of continent-wide annual and long-term indices of population size changes of 170 species. Here, we present the database and provide a detailed summary of the methodology used for fieldwork and calculation of the relative population size change estimates. We also provide a brief overview of how the data are used in research, conservation and policy. We believe this unique database, based on decades of bird monitoring alongside the comprehensive summary of its methodology, will facilitate and encourage further use of the Pan-European Common Bird Monitoring Scheme results.publishedVersio
