    International audience; We study the cross-sectional dispersion of prices paid by EMU importers for French products. We document a significant level of dispersion in unit values both within product categories across exporters, and within exporters across buyers. This latter source of price discrepancies, which we call price discrimination, reflects the ability of exporters to sell similar or differentiated varieties of a given product at different prices to different buyers. Price discrimination (i) is substantial within the EU, within the euro area, and within EMU countries; (ii) has not decreased over the last two decades; (iii) is more prevalent among the largest firms and for more differentiated products; (iv) is lower among retailers and wholesalers; (v) is also observed within almost perfectly homogenous product categories, which suggests that a non-negligible share of price discrimination is partly triggered by heterogeneous markups rather than quality or composition effects. We then estimate a rich statistical decomposition of the variance of prices to shed light on exporters' pricing strategies.

    International audience; Avant de se propager à l’échelle mondiale, l’épidémie de coronavirus est apparue dans la province du Hubei. Pour contenir la propagation du virus, le gouvernement chinois a imposé des mesures de quarantaine, entraînant un ralentissement de l’activité économique. Nous étudions ici la manière dont ce ralentissement de la production, initialement limité à la province de Hubei, se diffuse à l’économie mondiale via les chaînes de valeur internationales. La dépendance à l’égard des intrants chinois a augmenté de manière spectaculaire depuis le début des années 2000. De ce fait, la plupart des pays sont exposés au ralentissement de l’activité en Chine, à la fois directement via leurs importations de produits intermédiaires chinois et indirectement, du fait de la valeur ajoutée chinoise incorporée à d’autres intrants à la production. Cette note quantifie l’exposition totale de la France comparée à celle d’autres pays. Dans un premier temps, nous calculons la part de la valeur ajoutée chinoise dans la production française. Ensuite, nous utilisons des données au niveau des pays et des secteurs pour quantifier l’impact des mesures de quarantaine sur le PIB français.

    International audience; Before spreading globally, the Covid-19 epidemic was concentrated in the Hubei province. To contain the spread of the virus, the Chinese government has imposed quarantine measures and travel restrictions, entailing the slowdown of economic activity. We study the propagation of this geographically concentrated productivity slowdown to the global economy, through global value chains. Reliance on Chinese inputs has dramatically increased since the early 2000s. As a consequence, most countries are exposed to the Chinese productivity slowdown, both directly through their imports of Chinese inputs and indirectly, through other inputs themselves produced with some Chinese value added. This note aims at quantifying the total exposure of France compared to other countries. First, we compute the share of Chinese value added in French production. Then, we use data at the country and sector levels to quantify the impact of travel restrictions on French GDP.

    International audience; More than three years after the unexpected Brexit vote of June 2016, there is still no exit agreement between the United Kingdom and the European Union. Although the conditions of Brexit and the corresponding economic consequences are still unknown, the referendum has already had a real economic impact. The long discussion surrounding Brexit can be seen as a long-lasting uncertainty shock, whiach has affected firms’ investment decisions.In this note we use highly detailed customs data before and after the vote to measure the impact of Brexit on French firms’ exports to the UK. We find that the referendum had no effect on average on the value of exports but depressed export growth in sectors such as transportation or chemical industries which are more upstream in value chains. The number of new trade relationships involving French exporters and British importers has significantly declined after the Brexit vote, in comparison with other destinations. This is consistent with the uncertainty shock reducing French firms’ investment in their customer base, which is likely to penalize French exporters in the future. These results are suggestive evidence that uncertainty has a real cost and that any decision of delaying the Brexit further should compare the benefit of reaching a better deal with the economic cost induced by uncertainty. It is also important that the next EU-UK trade agreement should guarantee the stability and predictability of the trade policy that European exporters will have to face.

This paper investigates the role of individual firms in international business-cycle comovement using data covering the universe of French firm-level value added and international linkages over the period 1993–2007. At the micro level, trade and multinational linkages with a particular foreign country are associated with a significantly higher correlation between a firm and that foreign country. The impact of direct linkages on comovement at the micro level has significant macro implications. Without those linkages the correlation between France and foreign countries would fall by about 0.098, or one-third of the observed average correlation of 0.291 in our sample of partner countries.
