Climate policies do not operate in isolation but propagate through global production networks, affecting industries beyond national borders. This paper combines international input-output data with a granular instrumental variable approach to capture how foreign regulations transmit through upstream and downstream linkages. Distinguishing between market-based policies, non-market regulations, and technology support, the analysis shows that foreign climate policies can enhance domestic productivity, with effects shaped by industry characteristics and operating through technological adjustment along supply chains. The results underscore the importance of accounting for international spillovers when evaluating the economic impact of environmental regulation.

Since the onset of globalization, production activities have become increasingly fragmented and organized in global value chains, facilitating the trade of intermediaries across industries and countries. In this paper, we analyze the dynamic effect of increasing participation in global value chains on both productivity growth and the functional income distribution. To account for potential endogeneity, we construct a granular instrumental variable for international trade integration using detailed international input-output tables. Our findings show on the country-industry level, that both trade in intermediate inputs and trade in value-added significantly raise productivity in advanced countries, at the expense of the labor share of income. Moreover, labor shares decline more sharply in both manufacturing and services sectors, as well as in industries positioned closer to the final stages of the global value chain. Finally, our results show that a decline in international trade integration would have substantial negative effects on long-term productivity growth.

Containment measures of COVID-19 have generated a chain of supply and demand shocks around the globe with heterogeneous fallout across industries and countries. We quantify their transmission via foreign trade with a focus on the euro area where deep firms integration within regional supply chains and strong demand linkages act as a magnification mechanism. We estimate that spillover effects in the euro area from suppression measures in one of the five main euro area countries range between 15-28% the size of the original shock; negative foreign demand shocks depress euro area aggregate activity by about a fifth the size of the external shock and a fourth of the total effect is due to indirect propagation through euro area supply chain. Last, reopening to regional tourism softened the contraction of aggregate activity due to travel and tourism bans by about a third in the euro area. Our findings suggest that enhanced coordination of recovery plans would magnify their beneficial effects.

Anhand einer Input-Output-Analyse wird gezeigt, dass für die Wertschöpfungsketten der Exportgüterproduktion in Deutschland weder die Daten während des Globalisierungsschubs um die Jahrtausendwende noch die Daten während der Wirtschafts- und Finanzkrise und danach den Verlust an Arbeitsplätzen und Einkommen infolge der wachsenden Importdurchdringung der nationalen Produktion belegen können. Im Gegenteil wird gezeigt, dass Deutschland dank seiner Stärke auf den internationalen Märkten von der Auslagerung einzelner Arbeitsschritte und ganzer Produktionsstufen profitiert hat.

Global value chains (GVCs) - referring to the cross-border flows of goods, investment, services, know-how and people associated with international production networks - have transformed the world. Their emergence has resulted in a complete reconfiguration of world trade, bearing a strong impact on the assessment of competitiveness and economic policy. The contributions to this eBook are based on research carried out within the scope of the Eurosystem Competitiveness Research Network (CompNet), bringing together participants from EU national central banks, universities and international organisations interested in competitiveness issues. The mapping of GVCs and full awareness about their implications are essential to informed public debate and improved economic policy. 

This interim report summarises the main findings of the Competitiveness Research Network (CompNet) after one year of existence. The Network is organized in three workstreams related to: (i) aggregate measures of competitiveness; (ii) firm-level studies; and (iii) global value chains (GVCs). The main objectives of the Network are to improve the existing frameworks and indicators of competitiveness across all dimensions (macro, micro and cross-border) and establish a more solid connection between identified competitiveness drivers and resulting outcomes (trade, aggregate productivity, employment, growth and essentially welfare), in order to support the design of adequate policies.

This paper analyzes the performance of global value chains during the trade collapse. To do so, it exploits a unique transaction-level dataset on French firms containing information on cross-border monthly transactions matched with data on worldwide intrafirm linkages as defined by property rights (multinational business groups, hierarchies of firms). This newly assembled dataset allows us to distinguish firm-level transactions among two alternative organizational modes of global value chains: internalization of activities (intragroup trade/trade among related parties) or establishment of supply contracts (arm's length trade/trade among unrelated parties). After an overall assessment of the role of global value chains during the trade collapse, we document that intra-group trade in intermediates was characterized by a faster drop followed by a faster recovery than arm's length trade. Amplified fluctuations in terms of trade elasticities by value chains have been referred to as the "bullwhip effect" and have been attributed to the adjustment of inventories within supply chains. In this paper we first confirm the existence of such an effect due to trade in intermediates, and we underline the role that different organizational modes can play in driving this adjustment.

Die zurückliegenden Jahrzehnte waren weltweit durch eine erhebliche Ausweitung der internationalen Handelsströme, nicht nur absolut, sondern auch in Relation zum Welt-BIP, gekennzeichnet. Dies ist zu einem Großteil auf den zunehmenden bilateralen Handel mit Vor- und Zwischenprodukten als Folge der internationalen Fragmentierung der Produktion zurückzuführen. Offensichtlich hat der im Laufe der Zeit zunehmende internationale Wettbewerbsdruck, insbesondere seitens der südostasiatischen und der mittel- und osteuropäischen Länder, die Unternehmen in Hochlohnländern veranlasst, internationale Unterschiede in den Faktorpreisen, vor allem in den Arbeitskosten, zur Steigerung ihrer preislichen Wettbewerbsfähigkeit auszunutzen. Allerdings wird die Verlagerung von Teilelementen der Wertschöpfungsketten ins Ausland aus theoretischer Sicht, neben Faktorpreisunterschieden, von einer Vielzahl weiterer Faktoren bestimmt. Vor diesem Hintergrund veranschaulicht der vorliegende Artikel auf der Basis bilateraler Daten zum Außenhandel mit Vor- und Zwischenprodukten das Ausmaß der internationalen Fragmentierung der Produktion in der Europäischen Union. Zudem werden im Rahmen einer Paneldaten-Analyse die wesentlichen erklärenden Größen der vertikalen Aufspaltung von Wertschöpfungsketten bestimmt. Die Ergebnisse zeigen, dass internationale Unterschiede in den Arbeitskosten zwar ein wesentlicher, aber dennoch nur ein erklärender Faktor unter vielen sind.
