EMU and trade: A PPML re-assessment with intra-national trade flows

This paper examines the EMU effect on trade for the eleven early joiners and Greece relying for the first time on data that include both international and intra-national trade flows, in line with all the microfoundations of the structural gravity model of trade. We find that the overall EMU impact on trade is positive between its members and, specially, for trade between members and non-members. Interestingly, we further show that the effect of the EMU on bilateral trade remarkably differs across countries. For Ireland, Belgium–Luxembourg, Spain, Portugal and Austria, we find robust evidence that EMU has boosted trade both with other members and with third countries, while for Finland, France, Germany, Italy and the Netherlands, the results suggest that only trade with third countries has been enhanced by the EMU. Greece is the only country that shows a negative impact in trade with other EMU members and no effect in trade with non-members. Finally, the results across countries according to the direction of the trade flows (exports versus imports) do not show significant differences in any case.     

Thick and Thin Borders in the European Union: How Deep Internal Integration is Within Countries,and How Shallow Between Them

The existence of large border effects is one of the main puzzles of international macroeconomics. The seminal paper by McCallum found that trade between any two Canadian provinces was (on average) 22 times greater than trade between any Canadian province and any US state. Although various authors have estimated internal and external border effects for the whole European Union and some specific European countries, none has done so in the manner that McCallum's seminal paper, stymied by lack of data on region‐to‐region international trade flows. This study uses a novel data set that captures intra and international truck shipments between Spanish regions and regions in seven European countries during the period 2004–11. It computes internal and external border effects, offering novel results for aggregate flows and the importing countries, and estimates several specifications of the gravity equation, so as to tackle such issues as the multilateral resistance term, heteroscedasticity, and zero flows and non‐linear relation between trade and distance. The paper also adds a detailed analysis on the external border effect for each Spanish exporting region and each of the seven European countries considered. By means of this analysis, we shed new light on the relative integration between regions of these seven countries and Spanish exporting regions. Finally, we conduct an extrapolation exercise, computing the ‘trade potentials’ that would be expected in a fully integrated Europe and estimating how long full integration would take to achieve between each Spanish exporting region and each European importing country. To this regard, two alternative scenarios are considered: one using the growth rates of the Spanish exports before the crisis (2001–08) and other considering the post‐crisis growth rates (2011–13).     

EMU and Trade Revisited: Long‐Run Evidence Using Gravity Equations

In this paper, we present evidence of the long‐run effect of the euro on trade for the twelve initial EMU countries for the period 1967–2008 from a double perspective. First, we pool all the bilateral combinations of trade flows among the EMU countries in a panel cointegration gravity specification. Second, we estimate a gravity equation for each of the EMU members vis‐à‐vis the other eleven partners. We apply panel cointegration techniques based on factor models that account for cross‐dependence and structural breaks. Whereas the joint gravity equation provides evidence on the aggregate effect of the euro on intra‐European trade, by isolating the individual countries, we assess which of the member countries have obtained a larger benefit from the euro. The results show that the euro has had a positive though small effect on trade. Belgium and Luxembourg, France and Italy are the countries more benefited from the introduction of the euro. The effects for exports to third countries are in general more moderate, and, with the exception of Greece, there is no evidence of diversion effects.     

Governance and Globalisation

Unlike the large literature on ‘democracy and trade’, there is a much smaller literature on the effect of the level of democracy in a nation on the level of its foreign direct investment (FDI) inflow. These few studies reveal mixed empirical results, and surprisingly only one study has examined bilateral FDI flows. Moreover, few of these studies use multiple governance indicators separating the ‘pluralism’ effect of democratic institutions from the ‘good governance’ effect, there are no studies on democratic institutions’ various effects on the level of FDI relative to trade, and there are no studies of democratic institutions’ various effects on the selection of countries into FDI. We focus on three contributions. First, we examine the simultaneous effects of the World Bank's (six) Worldwide Governance Indicators (WGIs) – which allow separating the effects of pluralism from those of five other good governance measures – on bilateral trade, FDI and FDI relative to trade using state‐of‐the‐art gravity specifications. Second, we find strong evidence that – after accounting for host governments’ effectiveness in various roles of good governance – a higher level of pluralism as measured by the WGIs’ Voice and Accountability Index reduces trade levels, likely by increasing the ‘voice’ of more protectionist less‐skilled workers, but not FDI levels. Moreover, we find qualitatively different effects of other WGIs – such as political stability – on trade versus FDI flows. Third, we account for firm heterogeneity alongside a large number of zeros in bilateral FDI flows using recent advances in gravity modelling. We distinguish between the (country) intensive and extensive margins and show that pluralism affects FDI inflows negatively at the intensive margin, but positively at the extensive margin.     

The determinants of cross-border equity flows

We explore a new panel data set on bilateral gross cross-border equity flows between 14 countries, 1989-1996. We show that a “gravity” model explains international transactions in financial assets at least as well as goods trade transactions. Gross transaction flows depend on market size in source and destination country as well as trading costs, in which both information and the transaction technology play a role. Distance proxies some information costs, and other variables explicitly represent information transmission, an information asymmetry between domestic and foreign investors, and the efficiency of transactions. The geography of information is the main determinant of the pattern of international transactions, while there is weak support in our data for the diversification motive, once we control for the informational friction. We broaden the scope of our results by presenting some evidence linking the results on equity transactions to equity holdings.     

The role of inbound tourist flows in promoting exports

While it is established that tourism benefits growth through increased employment and investments, it is not well understood whether tourism has an effect on exports. This paper explores exports as an additional channel through which tourism affects domestic economic activity. Using bilateral tourist and trade flows, the paper explores the causal effect of tourist flows on exports. To deal with endogeneity, two instruments are constructed and subsequently used on two different sets of exporters, one of the instruments being the number of casualties due to terrorism in a country. We find that tourism affects mainly the exports of differentiated products. Specifically, we find that tourism benefits the exports from non‐OECD exporters of processed food products and this effect is only estimated for South–North trade with an elasticity close to 1. For European countries, the findings point in the same direction; tourism affects differentiated consumer products and processed food with elasticity close to 1, which adds plausibility to the earlier results. We also find a lagged effect for tourism mainly on the export of consumer goods (for the two samples) and processed food products (for European countries). The results suggest that exporting is an additional channel through which tourism can stimulate domestic economic activity in the tourist destination.     

Temporary Migration and Bilateral Trade Flows

Empirical evidence on migration and trade has established that permanent migration promotes trade. This finding has been interpreted as proof for the role of migrants in reducing trade‐related transaction costs such as contract enforcement costs or information costs. This paper contributes to improving our understanding of trade‐related transaction costs by analysing empirically whether temporary migrants, like permanent migrants, have an impact on bilateral trade flows. Temporary migrants can be expected to be less integrated in the host country than permanent migrants. At the same time, their knowledge of the home country can, on average, be expected to be more up‐to‐date. Our findings therefore give insights as to the relative importance of knowledge on the host and the home country for trade‐related transaction costs. Using a gravity approach in our empirical analysis, we find that temporary migration has a positive and significant effect on trade and that temporary migration tends to have a stronger and more significant effect on both imports and exports than permanent migration. Interestingly, the role of temporary migrants in reducing trade costs does not appear to be associated with their skills.     

Aid,trade and migration: How do bilateral flows interact?

This paper takes as its point of departure the European Commission's position, set out in 2005, which laid clear emphasis on aid and trade as tools for controlling immigration. We attempt to subject this position to empirical investigation. We exploit data on bilateral aid, trade and migration flows between developed and developing countries, for the period 2000–10, adopting an instrumental variable approach to address the endogeneity issue due to potential simultaneity bias. Our results establish that increasing aid and trade with developing countries is likely to fail to contain immigration, at least in the short run. The pattern of results is consistent with the hypothesis that promoting development in migrant‐sending countries, or cooperating with such countries to control migration outflows, is not sufficient to lessen immigration. Increasing visa restrictions and controls at borders is generally controversial; still, the results imply that policymakers cannot attain their short‐term immigration goals with the so‐called smart solutions of aid and trade.     

Migration and institutions: Evidence from internal EU mobility

Despite the formal achievement of the free movement of labour within the EU , the institutional characteristics of the labour markets of the Member States may influence European mobility. The paper seeks empirical evidence of the relationship between labour market institutions and intra‐EU migrations, estimating a gravity model for bilateral migration for the period 2001–11. The results indicate that trade union density negatively correlates with the size of bilateral migrations: destinations with relatively high union density are associated with lower migration inflows. Since these countries tend to have a relatively flat earnings distribution, it is also investigated whether their earnings structure reduces their attractiveness as destinations hindering the access to their labour market. Even if a dependence between the earnings dispersion and migrations is found, trade union density remains the main driver of migration patterns. Clear effects of employment protection on EU mobility are not found.     

The effects of bilateral attitudes on imports

Research based on the gravity model has shown that non-economic factors affect international trade, and recent studies have shown that people's perception affects economic exchange. In this study, we explore the effects of attitudes on bilateral trade. Using survey data from the Pew Research Center's Global Attitudes Projects for 68 countries from 2002 to 2015, we find that a more favourable attitude of a country towards another country will increase the former country's imports from the latter. The result is robust to an endogeneity check, to different measures of attitudes and to different estimation methods. However, heterogeneity is observed across different types of goods and countries. The result holds for trade in intermediate and consumer goods, but the effects are not statistically significant for capital goods. The effects are statistically significant for bilateral trade between different country groups, except for high-income countries' imports from non-high-income countries.     

Do Economic Integration Agreements Actually Work? Issues in Understanding the Causes and Consequences of the Growth of Regionalism

This paper argues that the ‘competitive liberalisation’ of national governments of the past several decades has created a ‘market’ for regional economic integration agreements (EIAs). Evidence shows that countries that have selected into EIAs – such as free trade agreements – have ‘chosen well’ in the sense that the same economic characteristics that explain and predict bilateral EIAs also explain and predict bilateral trade flows. We show that previous ex post empirical evaluations of the effects of EIAs on trade have tended to underestimate the effects due to ignoring the (endogenous) self‐selection bias of country pairs into EIAs. Accounting for this bias, we find that European economic integration had a much larger impact on trade over the period 1960–2000 than previously found, and other more recent EIAs have had economically and statistically significant effects on members’ trade. The results shed further light on understanding the causes and consequences of the growth of regionalism.     

The Tradability of Services within Canada and the European Union

This paper analyses bilateral trade flows between the provinces of Canada and between the member states of the European Union using a gravity model. On average, distance is less a hindrance for services trade than for goods trade. Language and regulation differences hamper intra-EU trade significantly. Services trade, in contrast to goods trade, is also hampered by the level of regulation in the importing country. Services trade within Canada as a share of GDP is twice the intra-EU level, and estimates suggest that intra-EU services trade could more than double if the internal market functioned like the Canadian services market.     

The Relationship between Political Tensions,Trade and Capital Flows in ASEAN Plus Three

We estimate the effects of political tension on trade and capital flows in ASEAN Plus Three countries in the framework of a gravity model. We quantify political tension through text‐parsing software reading daily Reuters’ articles from 1990 to 2013 and exclude Brunei and Laos due to sparsity of news coverage. Regarding bilateral trade, we find that political conflict, measured by negative reports in Reuters’ articles, seems to only affect bilateral trade between countries that are not both members of the World Trade Organization (WTO). For these countries, a 1 per cent rise in the tension score results in a 0.05 per cent decline in trade. There is weaker evidence that improvement in bilateral relationship, measured by positive reports in Reuters’ articles, is associated with more trade. As for capital flows, while long‐term capital flows, measured by foreign direct investment, appear to be unaffected by short‐term tensions, both a non‐democratic government and a history of war negatively affect FDI.     

The Determinants of EU Processing Trade

This paper assesses the determinants of European outward and inward processing trade. Thereby, it distinguishes between size, relative factor endowment, (other) cost factors and infrastructure variables. Using a large panel of bilateral processing trade flows of the EU12 countries at the aggregate level over the period 1988–1999, we find that infrastructure variables, relative factor endowments and other cost variables are important determinants for the EU's outward processing trade. Costs also play a key role for the EU's inward processing trade.     

Regional Integration and Trade: Controlling for Varying Degrees of Heterogeneity in the Gravity Model

The proliferation of regional trade agreements (RTAs) in the 1990s prompted a renewal of interest in studying the effect of regional integration on trade. Using a panel dataset of bilateral export flows from 12 EU countries to 20 OECD trading partners over the period 1992–2003, the trade effect of European regional integration, denoted by an EU dummy, is examined across a number of fixed effects (FE) specifications, each of which has been claimed as the correct econometric specification of the gravity model. Typically parsimonious in (time‐varying) economic variables and abundant in fixed effects, the FE specifications allow for varying degrees of heterogeneity in the gravity model. Two gravity models are estimated: a gravity model of traditional trade determinants and a gravity model of new trade theory (NTT) determinants. Both gravity models provide reasonable coefficient estimates, although they vary somewhat across the FE specifications for the traditional gravity model. Both gravity models are congruent in suggesting that the coefficient of the EU dummy declines in magnitude and becomes insignificant as an increasing degree of heterogeneity is admitted into the model. This suggests the fundamental importance of the econometric specification when evaluating trade policy effects within a gravity framework.     

Determinants of International Student Migration

This paper considers what factors determine the migration of overseas students, when students cross borders for higher education. We utilise a gravity model for international student mobility and derive estimates for a sample of 18 countries of destination and 38 countries of origin over the period 2005–11. Our results confirm that geographical distance and the presence of a common language are powerful in explaining bilateral student flows. Our most interesting finding is that time zone differences have a statistically significant and economically large effect in determining international student flows.     

A knowledge-and-physical-capital model of international trade flows, foreign direct investment, and multinational enterprises

This paper addresses two important issues at the nexus of the literatures on international trade, foreign direct investment (FDI), foreign affiliate sales (FAS), and multinational enterprises (MNEs). First, the introduction of a third internationally-mobile factor (physical capital) to the standard 2 × 2 × 2 “knowledge-capital” model of MNEs with skilled and unskilled labor allows us to resolve fairly readily the puzzle in the modern MNE literature that foreign affiliate sales among two identical economies completely displace their international trade. Intra-industry trade and intra-industry FDI (and FAS) can coexist for national and multinational firms (with identical productivities) in identical countries. Second, the introduction also of a third country to the model suggests a formal N-country theoretical rationale for estimating gravity equations of bilateral FDI flows and FAS, in a manner consistent with estimating gravity equations for bilateral trade flows.     

The Role of Geography in Financial and Economic Integration: A Comparative Analysis of Foreign Direct Investment,Trade and Portfolio Investment Flows

The objective of this paper is to examine the role of geography in explaining the patterns of financial and economic integration among both developed and developing countries. Using a gravity model, we compare North‐North, North‐South and South‐North FDI, trade and portfolio investment flows to examine how geographical factors influence these bilateral flows. The results indicate that the impact of geography variables on FDI and portfolio are similar to their effect on trade. Geography variables have a statistically significant effect both on FDI and portfolio investment, but FDI is more sensitive to distance. We interpret the negative effect of distance as the existence of information costs in financial flows. Also bilateral FDI, trade and portfolio investment flows react to macroeconomic fundamentals in the same way, however, with different degrees of sensitivity. There are significant differences between North‐North and North‐South flows. Our results find support for the argument that most FDI among industrial countries are horizontal, whereas most FDI investment in developing countries is vertical. The fact that the significance of geographical variables on financial flows still remained even after controlling for the macroeconomic fundamentals, is in contrast with the standard capital market model. The results can, however, be reconciled if geographical factors can proxy for information costs, which may in turn explain why country portfolios are still home‐biased. The significant effect of distance on financial flows may also explain how idiosyn cratic shocks are spread (i.e. contagion) to other countries in the same region. Ultimately, the geographical location of a country may determine its economic and financial integration into the world economy.     

Modes of Foreign Direct Investment and Patterns of Trade: An Alternative Empirical Approach

Modes of FDI can be clarified by analysing the changing patterns of trade among host, home and third countries. However, most empirical experiments of foreign direct investment (FDI) determinants have been confined to general characteristics of host countries and multinational enterprises' outward investment activities. This may not clearly characterise the specific characteristics of inward FDI in regard to the host country. Thus, we introduce an alternative approach to clarify modes of FDI by investigating the link between patterns of trade and inward FDI. To empirically test whether our approach is applicable, we choose China during the period 1998–2007. We construct a modified gravity equation of bilateral trade while considering spatially lagged interdependence between host, home and third countries. The problem of endogeneity is controlled by applying the system generalised method of moments (GMM) estimation technique. Our findings are consistent with results in existing studies on modes of outward FDI to China and prove that our approach in dealing with the link between patterns of trade and inward FDI has wide applicability to all modes of FDI. We discover there is strong evidence for statistically significant complementarity between bilateral trade and inward FDI within the aggregate trade data. As we decompose the aggregate trade data into final and intermediate goods, we find the motivation concerning export‐platform and complex vertical FDI is very significant. In addition, as we separate the bilateral partners into developing partners and developed partners, we find both bilateral and multilateral linkages are much stronger with developing partners.     

Market Structure and Market Access

We explore an issue at the nexus of domestic competition policy and international trade, the interaction between goods trade and market power in domestic trade and distribution sectors. We examine the effect of variations in conditions of domestic competition in services on trade volumes in goods in the cases of both linear and nonlinear import demand, including standard form CES‐based gravity models of bilateral trade flows. Theory suggests a set of linkages between service‐sector pricing and goods trade supported by econometrics involving imports of 22 OECD countries vis‐a‐vis 69 exporters. Competition in distribution services affects the volume of trade in goods. Additionally, because of interaction between tariffs and pricing, the market structure of the domestic service sector becomes increasingly important as tariffs are reduced. Indeed, depending on the degree of competition, market access concessions on tariffs may be effectively undone in some cases by changes in margins. For exporters, we find that service competition in destination markets matters most for exporters from smaller, poorer countries. Our results also suggest that while negotiated agreements leading to cross‐border services liberalisation may boost goods trade as well, they may also lead to a fall in goods trade when such liberalisation involves FDI leading to increased service sector concentration.
