The effect of the Uruguay Round on the intensive and extensive margins of trade

Do tariffs inhibit trade flows by limiting the entry of exporting firms (`extensive margin') or by restricting the average volume exported by each firm (`intensive margin')? Using a gravity equation approach, we analyze how the decrease in tariffs promoted during the 1990s by the Uruguay Round multilateral trade agreement affected the trade margins of French firms across 57 sectors and in 147 countries, from 1993 to 2002. Our main contribution is to estimate the elasticity of trade for both margins, controlling for the unobserved heterogeneity of trade flows thanks to a three-dimensional panel and to time-varying tariffs as a measure of variable trade costs. Our results show that the number of firms exporting in a given sector to a given destination is related to the level of tariffs. But they also show that the decrease in tariffs determined by the implementation of the Uruguay Round did not lead more firms to export and instead, only encouraged incumbent exporters to increase their shipments. We control for two problems that may affect our basic specification: tariff changes may be endogenous and zero flows are not included. Our results are confirmed - even when the extensive margin is significant, its contribution is very small.tariffs, trade margins, Uruguay Round

A new approach for better industrial strategies

Industrial policy is back. After having been considered a taboo since the 1970s, “new industrial policies” are at the core of governments’ strategies to support countries during crises and enable the green and digital transitions. Virtually, every government has used and uses industrial policy, despite continued concerns related to anticompetitive effects, within and across countries, captured by vested interests and the opportunity cost of public funds, which economists have pointed out, based on previous unsuccessful experiences. In this paper, we contribute to the debate on industrial policy by presenting both a sound and simple framework to help design industrial policies and also data that allow the comparison of industrial strategies and their priorities across countries. First, this paper summarises our recent framework for industrial strategies, which is designed to offer practical policy advice and shed light on the complementarities between different policy instruments. Such a framework is particularly useful when designing complex mission-oriented industrial strategies promoting the green transition of the business sector. Second, this paper presents some salient results from the new “Quantifying Industrial Strategies” (QuIS) project, which gathers harmonised data on industrial policy expenditures, policy priorities, and policy instruments, thereby allowing the benchmarking of industrial strategies across countries. Based on the aforementioned conceptual framework, QuIS measures industrial policy expenditures across 9 OECD members, for the period 2019–2021. The data, now publicly available on the OECD website, show the importance of industrial policy expenditures, and the growing role of green industrial policies in countries industrial strategies

The effect of the Uruguay round on the intensive and extensive margins of trade

International audienceDo tariffs inhibit trade flows by limiting the entry of exporters (‘firm extensive margin’) or by restricting the average volume exported by each firm (‘firm intensive margin’)? Using a gravity equation approach, we analyze how the decrease in tariffs promoted during the 90s by the Uruguay Round multilateral trade agreement affected the trade margins of French firms for 57 sectors and 147 countries from 1993 to 2002.

Photographie du système socio-fiscal et de sa progressivité

International audienceDans le contexte actuel de consolidation budgétaire, les ménages sont amenés à contribuer au rétablissement des comptes publics. Cela donne lieu à de nombreux débats sur la manière de concilier cet effort avec la justice sociale et la solidarité. Une vision globale du système socio-fiscal français, malgré sa complexité, est un préalable nécessaire qui permet de nourrir ces débats

Wholesalers in international trade

International audienceRecent empirical research in international trade has revealed overwhelming evidence that, in all countries, a remarkably small proportion of firms report exports in Customs statistics. However, a large share of these are wholesalers. This suggests that the number of producers selling their products abroad might be much greater than that suggested by a simple count of the firms directly reporting their exports. This paper sheds light on the role of wholesalers in international trade. Our model uses very general assumptions to show that intermediated exporters may contribute significantly to the extension of countries' export opportunities. The model predicts a twofold role in international trade. First, wholesalers alleviate the difficulty of reaching less-accessible markets. Second, they help less-efficient firms to supply foreign markets, thus increasing the number of exported varieties at the aggregate level. We use French firm-level export data to provide empirical support for these two predictions

Wholesalers in International Trade

Recent empirical research in international trade has revealed overwhelming evidence that, in all countries, a remarkably small proportion of firms report exports in Customs statistics. A large share of these are wholesalers. This suggests that the number of firms active in foreign markets might be much greater than that suggested by a simple count of the firms directly reporting their exports. This paper thus sheds light on the role of wholesalers in international trade. Our model, which allows for quality differentiation, uses very general assumptions to show that intermediated exporters may contribute significantly to the extension of countries’ export opportunities. The model predicts a twofold role in international trade. First, wholesalers help less-efficient firms to supply foreign markets, thus increasing the number of exported varieties at the aggregate level.
