Changes in labor market institutions and the increasing integration of the world economy may affect the volatility of capital and labor incomes. This article documents and analyzes changes in income volatility using data for 11 industrialized countries, 22 industries and 35 years (1970–2004). The article has four main findings. First, the unconditional volatility of labor income has declined in parallel to the decline in macroeconomic volatility. Second, the industry-specific, idiosyncratic component of labor income volatility has hardly changed. Third, cross-sectional heterogeneity is substantial. If anything, the labor incomes of high- and low-skilled workers have become more volatile relative to the volatility of capital incomes. Fourth, the volatility of labor income relative to the volatility of capital income declines in the labor share. Trade openness has no clear-cut impact.

In recent decades, the international division of labor has expanded rapidly in the wake of European integration. In this context, especially Western European high-wage countries should have specialized on (human-)capital intensively manufactured goods and should have increasingly sourced labor-intensively manufactured goods, especially parts and components, from Eastern European low wage countries. Since this should be beneficial for the high-skilled and harmful to the lower-qualified workforce in high-wage countries, the opening up of Eastern Europe is often considered as a vital reason for increasing unemployment of the lower-qualified in Western Europe. This paper addresses this issue by analyzing the skill content of Western European countries’ bilateral trade using input-output techniques in order to evaluate possible effects of international trade on labor demand. Thereby, differences in factor inputs and production technologies have been considered, allowing for vertical product differentiation. In this case, skill content of bilateral exports and imports partially differs substantially, especially in bilateral trade between Western and Eastern European countries. According to the results, East-West trade should be harmful particularly to the medium-skilled in Western European countries.

The introduction of the Euro has been accompanied by the hope that international competition between EMU member states would increase due to higher price transparency. This paper contributes to the literature by analyzing price elasticities in international trade flows between Germany and France and between Germany and the United Kingdom before and after the introduction of the Euro. Using disaggregated Eurostat trade statistics, we adopt a heterogeneous dynamic panel framework for the estimation of price elasticities. We suggest a Kalman-filter approach to control for unobservable quality changes which otherwise would bias estimates of price elasticities. We divide the complete sample, which ranges from 1995 to 2008, into two sub-samples and show that price elasticities in trade between EMU members did not change substantially after the introduction of the Euro. Hence, we do not find evidence for an increase in international price competition resulting from EMU.

During the last decades, international trade flows of the industrialized countries became more and more intra-industry. At the same time, employment perspectives particularly of the low-skilled by tendency deteriorated in these countries. This phenomenon is often traced back to the fact that intra-industry trade (IIT), which should theoretically involve low labour market adjustment, became increasingly vertical in nature. Against this background, the present paper investigates the relationship between international trade patterns and selected labour market indicators in European countries. As the results show, neither inter- nor vertical intra-industry trade (VIIT) do have a verifiable effect on wage spread in EU member states. As far as structural unemployment is concerned, the latter increases only with the degree of countries’ specialization on capital intensively manufactured products in inter-industry trade relations. Only for unemployment of the less-skilled, a slightly significant impact of superior VIIT seems to exist.

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.

Heterogeneity in size and productivity is central to models that explain which manufacturing firms export. This study presents descriptive evidence on similar heterogeneity among international banks as financial services providers. A novel and detailed bank-level data set reveals the volume and mode of international activities for all German banks. Only a few, large banks have a commercial presence abroad, consistent with the size pecking order documented for manufacturing firms. However, the relationship between internationalization and productivity also yields two inconsistencies with recent trade models. First, virtually all banks hold at least some foreign assets, irrespective of size or productivity. Second, some fairly unproductive banks maintain commercial presences abroad.

The import penetration of exports has become a topic of public debate, particularly in the context of Germany’s position as one of the world’s leading exporters. The growth in the volume of intermediate products purchased from abroad for subsequent processing into export goods in Germany seems to be undermining the importance of exports as a driver of domestic production and employment. The gains that arise from an increase in exports seem to have been offset by the losses caused by the crowding out of local production by imports. Empirical evidence on the impact of this international integration of the goods market on the German labour market is ambiguous. Short-term negative effects on employment are claimed to be offset by the long-term benefit that the jobs lost in the short run will eventually be replaced by higher-skilled jobs with better

perspectives. Against this background, the following hypothesis is tested empirically: Germany is poor in natural resources, but rich in skilled labour. In line with the Heckscher- Ohlin theory, Germany should therefore specialize in the production of export goods and services that are relatively intensive in these factors and should import those goods and services that are relatively intensive in unskilled labour. The empirical part of the paper deals with the extent of the German export penetration by imports. At first, it analyses by what ways imports are affecting the exports directly and indirectly and shows the consequences of import penetration of exports for the national output and employment. Secondly, consequences for employment are split in different skill types of labour. These issues are discussed with the standard open static inputoutput- model. The data base is a time series of official input-output tables. The employment effects for Germany divided by skill types of labour are investigated using skill matrices generated by the authors.

The great trade collapse in the wake of the 2008-9 financial crisis provideda unique insight into the complexities inherent to international markets, and underlined a number of lessons for us to consider as we evaluate the shape of the global trade recovery. While the factors contributing to the crisis were diverse and multifaceted, it is arguable that persisting imbalances across the globe played a role. How will trade imbalances unwind and what is the role for policies influencing international transactions for goods and services? A precursor to answering this question is a broad understanding of how trade flows react to changes in the macroeconomy, and therefore much of this book will focus on recent assessments of the drivers of trade adjustment. A closely related concept affecting the degree to which countries trade is their relative competitive position. To tie in the chapters with the broader policy emphasis on competitiveness, we will also define and evaluate several drivers of international trade competitiveness.

In recent decades, the international division of labor expanded rapidly in course of globalization. In this context, highly developed countries specialized on (human) capital intensively manufactured goods and increasingly sourced parts and components from lowwage countries. Since this should be beneficial for the high-skilled and harmful for the lower qualified workforce, especially the opening up of Eastern Europe and the international integration of newly industrializing Asian economies are considered as main reasons for increasing unemployment of the lower qualified in high-wage countries. The present paper addresses this issue for selected Western European countries by analyzing factor content of trade, which allows inferring on factor demand patterns resulting from international trade. This is not only done for countries’ total external trade, but also for bilateral trade flows, using input-output analyses. Thereby, differences in factor inputs and production technologies are considered, allowing for product differentiation. According to the results, factor content of bilateral trade flows between Western European high-wage countries does hardly differ. However, the results are different for East-West trade, since exports from Western to Eastern Europe are distinctly more human capital intensively manufactured than imports of Western European high-wage countries from Eastern Europe.
