- Abstract
- We analyze, for the first time, how firms choose the currency in which they price transactions in international trade of services and investigate, using direct evidence, whether the US dollar (USD) plays a dominant role in services trade. Drawing on a new granular dataset on extra-European Union exports of Portuguese firms broken down by currency, we show that currency choices in services trade are active firm-level decisions. Firms that are larger and rely more on inputs priced in foreign currencies are less likely to use the domestic currency to export services. Importantly, we show that the USD has a dominant role as a vehicle currency in trade of services – but to a lesser extent than in trade of goods – and that this is not just due to differences in the geography of trade. An external validity test based on macro data available for Portugal and six other European countries confirms this finding. In line with predictions from recent theoretical models, our results are consistent with the lower prevalence of USD in services trade arising from a lower openness of services markets and a stronger reliance of services on domestic inputs.

- Abstract
- Global Value Chains (GVCs) became the paradigm for the production of most goods and services around the world. Hence, interconnections among countries can no longer be adequately assessed through standard bilateral gross trade flows and new methods of analysis are needed. In this paper, we compute measures of network analysis and apply visualisation tools to value added trade flows in order to understand the nature and dynamics of GVCs. The paper uses data on the bilateral foreign value added in exports for the period 1995-2011 and, in each year, GVCs are represented as directed networks of nodes (countries) and edges (value added flows). The analysis is extended beyond total trade flows to discuss the distinct roles of goods and services in GVCs. Moreover, the differences between Germany, the US, China and Russia as major suppliers of value added in GVCs are also examined.

- Abstract
- We show that credit supply shocks have a strong impact on firm-level as well as aggregate investment by applying the methodology developed by Amiti and Weinstein (2013) to a rich dataset of matched bank-firm loans in the Portuguese economy for the period 2005 to 2013. We argue that their decomposition framework can also be used in the presence of small firms with only one banking relationship as long as they account for only a small share of the total loan volume of their banks. The growth rate of individual loans in our dataset is decomposed into bank, firm, industry and common shocks. Adverse bank shocks are found to impair firm-level investment in all firms in our sample, but in particular for small firms and those with no access to alternative financing sources. For the economy as a whole, granular shocks in the banking system account for around 20-40% of aggregate investment dynamics.

- Abstract
- This paper describes the main features of Global Value Chains (GVCs) in the euro area taken as a whole and compares with other large trade players like the US, China and Japan. In addition, the perspective of individual euro area countries is considered, with a focus on intra euro area linkages. The analysis relies primarily on the concept of foreign value added in exports, as a way to assess the pervasiveness of GVCs, it covers the period 2000-2011 and bases on the World Input-Output Database (WIOD). The paper finds that GVCs are important for the euro area as whole and they have rebounded after the great trade collapse. Moreover, there is a strong relevance of regional production linkages in Europe, with Germany playing a key role.

- Abstract
- This article estimates price-cost margins for the Portuguese markets in a context of imperfect competition in the labour market. The database used includes virtually the universe of Portuguese firms for the period 2005-2009. The results strongly reject the hypothesis of perfect competition in both labour and product markets. Estimated price-cost margins are very heterogeneous across markets and the average for the overall economy ranges between 25 and 28 per cent, depending on the variables used to weight each market. In addition, the tradable sector presents a lower price-cost margin than the non-tradable sector. According to the methodology used, workers

- Abstract
- The production of most goods and services is nowadays vertically fragmented across different countries, as global value chains (GVCs) emerged as the current paradigm for the international organisation of production. This paper surveys part of the growing empirical literature on GVCs, starting by discussing the main driving forces of GVCs in recent decades. Next, it surveys the indicators used to map and measure this phenomenon, accounting for their different scopes and required datasets.

- Abstract
- Drawing from confidential firm-level balance sheets in 11 European countries, the paper presents a novel sectoral database of comparable productivity indicators built by members of the Competitiveness Research Network (CompNet) using a newly developed research infrastructure. Beyond aggregate information available from industry statistics of Eurostat or EU KLEMS, the paper provides information on the distribution of firms across several dimensions related to competitiveness, e.g. productivity and size. The database comprises so far 11 countries, with information for 58 sectors over the period 1995-2011. The paper documents the development of the new research infrastructure, describes the database, and shows some preliminary results. Among them, it shows that there is large heterogeneity in terms of firm productivity or size within narrowly defined industries in all countries. Productivity, and above all, size distribution are very skewed across countries, with a thick left-tail of low productive firms. Moreover, firms at both ends of the distribution show very different dynamics in terms of productivity and unit labour costs. Within-sector heterogeneity and productivity dispersion are positively correlated to aggregate productivity given the possibility of reallocating resources from less to more productive firms. To this extent, we show how allocative efficiency varies across countries, and more interestingly, over different periods of time. Finally, we apply the new database to illustrate the importance of productivity dispersion to explain aggregate trade results.

- Abstract
- This article segments the Portuguese economy into fairly disaggregated markets and estimates a new competition measure suggested by Boone (2008), which draws on the concept of profit elasticity to marginal costs. In addition, robustness of results across econometric specifications is discussed, along with their consistency with classical competition indicators. The article concludes that the majority of Portuguese markets exhibited a reduction in competition in the period 2000-2009, though there is substantial heterogeneity. In addition, markets that faced competition reductions represent the large majority of sales, gross value added and employment in the Portuguese economy. The non-tradable sector shows lower competition intensity than the tradable sector. Moreover, reductions in competition are relatively widespread across markets in both sectors, but in terms of sales, gross value added and employment these reductions are more substantial in the non-tradable sector. In the majority of markets the assessment on the evolution of competition using profit elasticities is similar to that obtained with classical competition indicators.

- Abstract
- This report aims to analyse euro area energy markets and the impact of energy price changes on the macroeconomy from a monetary policy perspective. The core task of the report is to analyse the impact of energy price developments on output and consumer prices. Nevertheless, understanding the link between energy price fluctuations, inflationary pressures and the role of monetary policy in reacting to such pressure requires a deeper look at the structure of the economy. Energy prices have presented a challenge for the Eurosystem, as the volatility of the energy component of consumer prices has been high since the creation of EMU. At the same time, a look back into the past may not necessarily be very informative for gauging the likely impact of energy price changes on overall inflation in the future. For instance, the reaction of HICP inflation to energy price fluctuations seems to have been more muted during the past decade than in earlier periods such as the 1970s.

- Abstract
- This paper analyses the degree of competition in the euro area services sector and its effects on labour productivity and relative prices in that sector over the period 1980-2003. The importance of the euro area services sector has significantly increased over time; it now accounts for around 70% of the euro area's total nominal value added and employment. Labour productivity growth across the euro area services industries appears to be characterised by a high degree of diversity and the level of services inflation is on average higher than aggregate inflation. Investigating several proxies of market competition for the non-financial business services, the paper finds that limited competition in services tends to hamper labour productivity growth in the services sector. Moreover, results tend to suggest that measures aimed at increasing services market competition may have a dampening impact on relative price changes in some services sectors and thus temporarily on aggregate inflation.
