Global trade flows and economic policy uncertainty

ABSTRACT

This article investigates the impacts of economic policy uncertainty (EPU) on global trade flows in gauging international trade developments. We employ a global vector autoregressive (GVAR) trade model, augmented with value-added bilateral trade linkages, that allows for quantifying the effects of economy-specific uncertainty shocks on exports and imports of individual economies. We find substantial spatial propagation in the temporal dynamics of international transmission of shocks amidst the manifestations of cross-border global value chains (GVCs) with China’s accession into the WTO. We provide evidence for the significance of EPU of China and the United States, particularly the latter, in influencing global trade flows. Our results show that while the US impacts can largely be attributed to its indirect trade linkages with other economies, the impacts of China can be relegated more to its direct GVC linkages. The findings have implications on trade protectionist inclinations of the current-term US government and the ongoing efforts of China’s policymakers in steering macroeconomic rebalancing for sustainable growth.     

The determinants of service exports from Central and Eastern Europe

The transition economies of Central and Eastern Europe (CEE) have become important exporters of many types of services to Western Europe. We identify the sources of CEE’s advantages over competing exporters, such as India, China and Brazil, using disaggregated data on service exports and a novel estimation technique for the gravity equation. Our results indicate that the importance of geographical distance varies substantially across types of service exports. Geography is important for exports of construction services, but it has a negligible impact on computer‐related services. However, the relative quality of legal institutions influences trade across a broad range of service categories. The results demonstrate that aggregating services that are not homogeneous could conceal important differences in the effects of geographical distance and other variables on the pattern of service trade.     

The new goods margin in new markets

We analyze the role of the new goods margin in the Baltic countries’ exports and imports growth during the 1995–2008 period. Using the methodology developed in Kehoe and Ruhl (2013), we define the set of least-traded goods as those that account for the lowest 10% of total exports and imports in 1995, and then trace its growth in several markets including the Baltics’ main trade partners, the European Union and Russia. We find that, on average, by 2008 least-traded goods accounted for nearly 50% of total Baltic exports to their main trade partners. Moreover, we find that increases in the share of least-traded exports coincided with the timing of the trade liberalization reforms implemented by the Baltic countries. Least-traded imports also grew at robust rates, but their growth was lower than that of exports, accounting for slightly less than a quarter of total imports, that is, about half of the exports value. Moreover, we find that the shares of least-traded imports from the EU 15 and from Russia started diverging around the time the Baltic countries joined the EU, with the EU 15 share increasing and the Russian one declining. We also find that the Baltics’ share of least-traded exports outpaced that of other economies in Central and Eastern Europe. Finally, exports of new goods from the Baltic countries suffered noticeably during the Global Financial Crisis. After the crisis ended, the restart in new goods exports growth displayed mixed patterns.     

Value-Added Erosion in Global Value Chains: An Empirical Assessment

In the period from 1995 to 2008, many countries experienced what we call the “value-added erosion.” It describes the decline in the sectoral shares of domestic value-added in a country’s exports as the country becomes more integrated into the global value chains (GVCs). We argue that the decline of the domestic value-added share in a country’s exports is likely to be caused by the expansion of high value-adding activities performed by foreign lead firms in the upper stream of the GVCs. The variables of interest — the domestic value-added share in exports and foreign high-skill labor embodied in a country’s exports (a proxy for foreign lead firms’ high value-adding activities) — are estimated using a multi-regional global input-output model. Using these results and other control variables, we apply a panel cointegration model to explain and assess the likelihood of value-added erosion and its possible determinants.     

Does the role of observer countries in the regional trade agreement matter for intra-regional trade ?

This article investigates the effects of trade by observed economies on the intra-regional trade by South Asian Association for Regional Cooperation (SAARC) members using Poison pseudo maximum likelihood estimator (PPML) gravity models with panel data over the period 2008–2014. Eight SAARC members and eight observed countries, including the EU, are analysed in capturing the trade effect of observed economies on intra-regional trade in SAARC. This article provides an empirical measure of observers’ trade, FDI and Official development assistance (ODA) with SAARC if the exports and imports of observers to/from SAARC have positive or negative signs for intra-regional exports and imports. The results show that the exports and imports of observers to SAARC members have positive effects on bilateral exports among the members. The FDI of observers reduces the bilateral intra-imports in SAARC and ODA also has a negative effect on bilateral exports among the members. These results imply that the imports by SAARC members from observer countries increase intra-regional trade in the region. The FDI and ODA increase and decrease intra-regional trade in SAARC, respectively, implying that the policies for both FDI inflow from observers and efficient aid management are needed to increase regional welfare. The study also recommends that trade between SAARC members and its observers help to increase intra-regional trade in SAARC.     

Trade Structure during Accession to the EU

This article discusses the degree of trade restructuring between the EU and the new member states during the accession process. Intra-industry trade is selected as a composite indicator of trade structure. Factor endowments, market size and distance are the most important determinants of intra-industry trade. The estimations for the OECD countries are used to compute predictions for EU15 trade with the CEE countries. In general, this approach predicts well the EU15 trade structure with CEE, which proves significant restructuring in the new member states. High shares of intra-industry trade imply lower welfare losses and less resistance to further deepening of integration in the participating countries.     

A note on the trade potential of Central and Eastern Europe

This paper discusses the results of recent studies which use the so-called ‘gravity’ approach to predict the potential volume and direction of the trade of Central and Eastern Europe (CEE). It also examines how the trade of the former socialist economies have evolved following external liberalization. It then compares the predictions made using the PPP based estimates of GDP for 1989 with actual 1992 trade data and the corrected predictions based on actual 1992 GDP figures. The results indicate that the CEE trade responded very quickly to the new regime and being redirected away from CMEA and towards EU markets. CEE's actual trade patterns do not now considerably differ from that of similar Western European countries. Moreover, the projection based on the data of 1992 do not indicate any remaining unused CEE trade potential.

Dimensions of quality upgrading

The impact of the Central and Eastern European (CEE) economies’ trade integration with European markets on CEE trade structures has been studied extensively. These studies frequently observe a quality upgrading of CEE exports. In this paper we consider three dimensions of quality upgrading: upgrading across industries, upgrading across different quality segments within industries and, finally, product upgrading within quality segments inside industries. For the analysis we partition industries into quality segments based on EU‐15 import unit values. The results for ten CEE countries (comprising the CEE‐5, the Baltics and South East Europe) and thirteen industries suggest fundamental differences, both across country groups and across the three different notions of quality upgrading. The CEE‐5 show no evidence of entering a ‘low‐quality trap’ in all three dimensions. By contrast, while there is a general catching‐up process across industries and inside quality segments, the second notion of low‐quality specialization may be applicable within the high‐tech industries to the performance for the Baltics and South East Europe as a group.     

Economic fluctuations in Central and Eastern Europe: the facts

This article provides a detailed empirical analysis of quarterly frequency dynamics in macroeconomic aggregates in 12 countries of Central and Eastern Europe (CEE). It shows that business fluctuations in CEE countries are, in general, more pronounced than in developed ones, and are of similar size as in other emerging market economies. Private consumption is particularly volatile. Relative to major developed economies government spending is dominantly procyclical, and net exports are strongly countercyclical. The most frequent country outliers are the high inflation countries of Bulgaria, Romania and Russia, especially in labour market, price and exchange rate variables. Excluding these countries from the sample makes many of the observed patterns in cyclical dynamics more homogenous, and broadly similar to ones established in developed economies.     

Trade liberalization and institutional reforms1

The accession of Central and Eastern European (CEE) countries to the European Union (EU) is expected to lead to the new member countries becoming more like the older members, including in terms of trade. In this paper, we focus on two factors promoting CEE–EU trade integration: trade liberalization and institutional reforms. Measures of trade liberalization undertaken by both parties during the 1990s were very substantial, but did not always produce the expected upsurge of regional trade flows. Much less progress has been made in improving the functioning of CEE institutions (e.g., progress in the privatization process or in reducing corruption). Countries where most important changes at the institutional level occurred were also those that most increased their trade with the EU. Comparing the impact of these two factors, we find that improving institutions in CEE countries can generate as much trade as the removal of all tariff and non‐tariff barriers. The paper also addresses the issue of the presence of reversed causality between trade and institutions, and the pro‐trade effect of institutional similarity.     

The economic and trade effects of the UK–Korea free trade agreement on the United Kingdom,Korea, Japan,China, and the European Union

We explored a comparative static computable general equilibrium model with six regions and 12 sectors to estimate the impacts of the recent UK–Korea free trade agreement (FTA) along with the European Union (EU)–Korea FTA. The empirical results provide quantitative evidence of the impact on national GDP, national exports and imports by sector, and the changes in exports or imports among the United Kingdom, Korea, Japan, China, and the EU. The UK–Korea FTA, along with the EU–Korea FTA, increases GDP and welfare for the United Kingdom and Korea; moreover, there is a large increase in automobiles, transport equipment, and machinery exports between Korea and the United Kingdom. The GDP and welfare level of non-member countries such as Japan and China will slightly decline. Exports from the United Kingdom and Korea to non-member countries are also expected to decrease in most manufacturing sectors. The UK–Korea FTA will lead to increases in imports between the United Kingdom and Korea due to mutual trade creation effects and trade diversion effects. However, non-member countries such as Japan's exports are expected to experience a large decline in automobiles to the United Kingdom and in most manufacturing products to Korea due to the negative impact of the UK–Korea FTA.     

Inequality and Income Distribution in Global Value Chains

Global value chains (GVCs), led by transnational corporations (TNCs), have reshaped the world division of labor over the past two decades. GVCs are pervasive in low technology manufacturing, such as textile and apparel, as well as in more advanced industries like automobiles, electronics, and machines. This hierarchical division of labor generates wild competition at the lower value-added stages of production, where low wages and low profit margins prevail for workers and contract manufacturers in developing countries. At the top of the hierarchy another kind of competition prevails, centered on the ability to monitor and control intellectual property rights related to innovation, finance, and marketing. We argue that GVCs have had crucial effects on income inequality and the appropriation of rents in modern capitalism.     

Urbanization with and without industrialization

We document a strong positive relationship between natural resource exports and urbanization in a sample of 116 developing nations over the period 1960–2010. In countries that are heavily dependent on resource exports, urbanization appears to be concentrated in “consumption cities” where the economies consist primarily of non-tradable services. These contrast with “production cities” that are more dependent on manufacturing in countries that have industrialized. Consumption cities in resource exporters also appear to perform worse along several measures of welfare. We offer a simple model of structural change that can explain the observed patterns of urbanization and the associated differences in city types. We note that although the development literature often assumes that urbanization is synonymous with industrialization, patterns differ markedly across developing countries. We discuss several possible implications for policy.     

Exports,imports, growth and causality: a study of Slovakia

In this article, we analyse the trade–growth nexus for Slovakia. This country represents a critical case for such research because it is one of the most open economies in the world; by several measures it is the most open economy in the EU, with the most Eurocentric trade, and has maintained one of the best growth performances within the EU over a sustained period of time. In contrast to most contributions to the trade–growth literature, we analyse all six possible causal relationships between Slovakia’s exports, imports and growth, using the technique developed by Toda and Yamamoto (1995), on quarterly data from 1997Q1 to 2014Q4. We find evidence supporting both the export-led-growth hypothesis and the import-led-growth hypothesis. None of the other four relationships was found to be significant.     

The pollution terms of trade and its five components

Based on two extensions, this paper proposes a re-appraisal of the concept of the pollution terms of trade (PTT) introduced by Antweiler (1996). First, detailed data allows capturing the effect of differences in emission intensities across countries and over time. Second, relying on Johnson and Noguera (2012), the revised PTT index controls for trade in intermediate goods and is based on value-added rather than gross output figures. Applied to a database for SO₂ emission intensities for 62 developed and developing countries over the 1990–2000 period, it turns out that the first extension has a larger empirical importance than the second one. The global pattern is one in which the major rich economies exhibit a PTT index below one (higher pollution intensity in imports than in exports). Trade imbalances tend to exacerbate this asymmetry, allowing rich economies to further offshore their pollution through trade.     

Market Power, Multinationality and Intra-Eu Industry Exports in the 90s

This paper assesses the impact of market power and multinationality in EU12 manufacturing industries on EU integration in goods trade in the 90s. An increase in the market concentration exhibits a positive impact on bilateral exports, while an increase in multinationality works in the opposite direction. Both effects are in accordance with the theoretical hypotheses. As a result, goods trade between the member countries was polarised in terms of a relative disintegration of southern Europe.     

Business-cycle synchronization in the EMU

This article asks whether the business cycles of the EU countries have become more or less synchronized after the introduction of the euro. Our findings show that all countries in our EU sample are better synchronized with the EMU-wide economy in the post-EMU period than they were before the euro. We also show that this increase in synchronization is present in all components of aggregate demand, as well as two supply-side variables, but it is more pronounced in the trade components (imports and, particularly, exports). It is also shown that the increase in trade within the EMU area is at least partly responsible for the increase in cyclical synchronization.     

Structural change and global value chains in the EU

Manufacturing activity in the EU is increasingly concentrated in a Central European (CE) manufacturing core implying divergent paths of structural change across Member States. This ‘manufacturing divide’ within Europe coincides with deepening economic integration in general and the emergence of global value chains (GVCs) in particular. Focusing on the manufacturing sector this paper investigates the relationship between structural change and integration into GVCs in EU Member States over the period 1995–2011. The empirical findings suggest a non-linear relationship between the two phenomena: members of the CE manufacturing core benefit from participation in GVCs in terms of structural change towards manufacturing, whereas in other EU Member States GVC participation, if anything, accelerates the deindustrialisation process.     

The (lack of) international harmonization of EU standards: import and export effects in developed versus developing countries

This article studies the effect of the lack of international harmonization in agri-food standards on international trade flows focusing on the European Union (EU). The EU is characterized by high level of protectionism, which makes it an ideal case study. We measure the differences in countries’ level of ‘protectionism’ by applying an index of aggregation of non-tariff measures to data on maximum residue levels on pesticides and veterinary drugs allowed by countries on agri-food products. The restrictiveness of countries standards’ is compared with the one imposed by the Codex Alimentarius, which is considered as non-protectionist. The EU emerges as the most rigorous standards setter. The higher standards imposed by the EU affect in particular imports from developing countries, while it facilitates its exports, irrespective of the level of development and standard restrictiveness set by the importing countries.
