Trade From Space: Shipping Networks and The Global Implications of Local Shocks by Inga Heiland and Pamina Koenig
This policy brief summarises the main results presented by Inga Heiland at the Globalization, Shipping and Trade workshop organised by the Chaire Mondialisation on 12 October 2023. It quantifies the direct and indirect effects of the widening of the Panama Canal in June 2016 on world trade flows and well-being. The results suggest that the global real income gains from the canal expansion were over three times greater than the income gains for Panama itself.
Plastic Turkey: International Leakages of China’s Waste Contamination Policy by Banu Demir, Deniz Atalar and Swati Dhingra
This policy brief summarizes the main findings presented by Banu Demir at the Paris Trade Seminar on 5 December 2023 on the dynamics of international trade flows of plastic waste and how they have been affected by China’s recent decision to stop importing plastic waste. It highlights the trade diversion effects and environmental consequences of the increase in plastic waste imports in countries that were not previously major users of imported waste, such as Turkey.

How Deep Trade Agreement Impact Firm’s Exports by Gianluca Orefice, Matteo Neri Lainé and Michele Ruta
In this policy brief, based on a paper presented at the workshop on RTAs organized by the Globalization Chair on November 7, 2023, Gianluca Orefice, Matteo Neri Lainé and Michele Ruta study the importance of the depth of preferential trade agreements signed by developing countries on the export performance of their companies. The authors point out that the impact varies greatly between companies depending on their size and their insertion in global value chains.

The Many Channels of Firm’s Adjustment to Energy Shocks: Evidence from France by Lionel Fontagné, Philippe Martin and Gianluca Orefice
In this policy brief, Lionel Fontagné and his co-authors study how French manufacturing companies have reacted to changes in energy prices over a long period. This granular approach, made possible by highly detailed new data, highlights the many channels (energy demand, export competitiveness, activity reallocation) through which manufacturing companies adjust to energy price rises.

Climate and the changing geography of the world economy by Lionel Fontagné
In this policy brief, Lionel Fontagné and his co-authors show how a macroeconometric model can be used to project world economic growth to 2050. This exercise highlights the upheaval in the global hierarchy of economies brought about by globalization and discusses how this matters for the fight against global warming.

The importance of Global value chains in International Trade and their consequences for Trade Policy by Pamina Koenig and Pol Antràs
Harvard professor Pol Antràs came to Paris to give a lecture as part of the Summer School on trade organized by the Paris School of Economics from 26 to 30 June 2023. He presented his work focusing on the measurement of global value chains (GVCs) and the way they have shaped economics research in the field of international trade. This policy brief, written by Pamina Koenig, presents an overview of the results, which includes the difficult quantification of global value chains, their impact on the complexity of production processes and the expected consequences of trade policies.

Corporate social responsibility and global value chains facing increased risks by Christoph Schiller and Jiaying Wei
This policy brief summarizes the main findings presented at the workshop organized by the Globalization Chair on June 20, 2023, on the impact of corporate social responsibility along the globalized value chain. Two guest researchers, Jiaying Wei, from the Southern University of Finance and Economics (China), and Christoph Schiller, from Arizona State University (USA), answered a few questions to explain their findings and how they shed light on the evolution of consumer and corporate awareness of higher environmental and social standards.
How did disruptions in in-person production affect global production and trade? Lessons from the recent COVID-19 pandemic by Maria Bas and Ana Fernandes
In this policy brief, Maria Bas and her co-authors study the short-term resilience of a large number of countries’ exports in the wake of the COVID-19 shock, and identify explanatory factors for differences in post-crisis export trends. They show that dependence on a small number of foreign input suppliers, notably from China, reinforced the contraction of exports, while the degree of automation of the production process boosted exports.
