A generalized design for bilateral trade flow models

This paper suggests a full interaction effects design to analyze bilateral trade flows. This is illustrated with an unbalanced panel of bilateral trade between the triad (EU15, USA and Japan) economies and their 57 most important trading partners over the period 1986–1997. Our full interaction model finds empirical support for the New Trade Theory and Linder’s hypothesis. We show that the omission of one or more interaction effects can result in biased estimates and misleading inference.     

The preliminary effectiveness of bilateral trade in China’s belt and road initiatives: a structural break approach

This study aims to investigate the initial effectiveness of the international trade in the Belt and Road Initiatives (BRI), which encompasses 64 countries along the Belt and Road as part of China’s political and economic network for the years beginning with 2013. To determine the initial effectiveness in the international trade associated with the BRI, we adopt the traditional augmented Dickey-Fuller (ADF) test and the one-time structural breakpoint in the bilateral trade data between China and these 64 countries along the Belt and Road from 2010 to 2017. The results show that, for 46 (72%) countries, the trade flows with unit roots and the shocks of trade flows appear to occur more frequently following the announcements of the initiatives among these countries. As for the remaining countries, the trade flows exhibit stationary time series over the 2010–2017 period. Both the 21st century maritime silk road and the silk road economic belt initiatives have affected the bilateral trade volumes of these countries along with the belt and road initiatives, and bilateral commerce mechanisms are able to serve as a stabilizing force in accelerating the economic integration of countries along the route.     

On the robustness of the trade-inducing effects of trade agreements and currency unions

Regional trade agreements (RTAs) and currency unions (CUs) are potentially endogenous trade cost proxies in equations estimating their effects on bilateral trade. In case of both, this problem is magnified by the paucity of reliable instruments. Instead of resorting to the oft-employed alternative of panel data to address selection on just the time-invariant unobservables, this paper assesses the extent to which a positive association between CU or RTA membership and bilateral trade can be considered causal. In addition, it attends to recent concerns over the extensive margin of trade (at the country-level) and the issue of zero trade observations in log-linearized gravity models by relying more on a bivariate probit analysis. Despite not identifying point estimates, striking results are obtained. While most cross-sections exhibit a positive association between both RTAs and CUs and trade, the evidence in favor of a robust causal effect is strong mainly for CUs. However, the magnitude of the CU effect is still sensitive to the amount of selection on unobservables. Moreover, selection into RTAs (CUs) is mostly found to be positive (negative). Finally, the presence of spillovers across the policy regimes is also detected.     

Moving to autarky,trade creation and home market effect: an exhaustive analysis of regional trade agreements in Africa

This article analyses the effects of Regional Trade Agreements (RTAs) on bilateral trade in Africa. A structural gravity equation is estimated over the period 1955–2014. The overall effect of RTAs on African trade is strong, but depending on the nature of the RTAs, there is a decreasing impact over time. While Economic Integration Agreements (EIAs) still favour trade in Africa, there was no trade creation coming from Free Trade Agreements between 1990 and 2014. However, the provisions of RTAs do not have a negative impact on trade: agreements that include behind-the-border policies do not significantly deter bilateral trade. To explain the declining impact of RTAs, we look at their redistributive impact between members states. There is no evidence that large countries disproportionally export diversified goods due to RTAs (no ‘home effect’). Countries with a good international network (‘hub effect’) benefited more than other countries of RTAs between 1955 and 1990 but this is however less true on the most recent period (1990–2014).     

Cultural proximity and trade

Cultural proximity is an important determinant of bilateral trade volumes. However, empirical quantification and testing are difficult due to the elusiveness of the concept and lack of observability. This paper draws on bilateral score data from the Eurovision Song Contest, a very popular pan-European television show, to construct a measure of cultural proximity which varies over time and within country pairs, and that correlates strongly with conventional indicators. Within the framework of a theory-grounded gravity model, we show that our measure positively affects trade volumes even if controlling for standard measures of cultural proximity and bilateral fixed effects.     

The global arms trade network 1950–2007

Using SIPRI data on all international transfers of major conventional weapons 1950–2007, we study the relationship between differences in polity and arms trade. To study whether states tend to trade arms within their political vicinity we estimate gravity models of the likelihood of trade at the bilateral level and study the evolution of the global network over time. We find a stable negative relationship between differences in polity and the likelihood of arms trade for the duration of the Cold War, but not in recent years. In line with these results, the global arms trade network changes drastically over the sample period in several respects: it grows more dense, clustered and decentralized over time. The differences between the NATO and Warsaw Pact sub-networks that we find corroborate the common perception that the Warsaw Pact was more strongly centralized around the USSR than NATO around the UK, the US and France.     

Do South–South preferential trade agreements undermine the prospects for multilateral free trade?

Due to trade diversion, there have been concerns expressed over the proliferation of preferential trade agreements (PTAs) that include South countries. In this paper, we compare welfare across different geographic configurations of bilateral free trade agreements (FTAs) and customs unions (CUs) and examine their implications for the stability of multilateral free trade. While North–North PTAs do tend to yield higher global welfare than South–South PTAs, a single South–South FTA may make free trade more sustainable than any other single agreement. With pre‐existing North–North agreements and a large enough cost asymmetry between regions, an additional South member or a new South–South agreement always makes free trade harder to sustain.     

US Security Strategy and the Gains from Bilateral Trade

We explore the geo‐strategic determinants of bilateral trade flows between the USA and the rest of the world. We develop a three‐party model of security and trade patterns and use data on military assistance and troop deployments over the 1950–2009 period to validate its predictions. We find that security assistance has significant, positive impacts on the shares of bilateral trade between the USA and the recipient country, results that are robust to issues of reverse causality and hold across different sectors.     

Exchange rate uncertainty and US bilateral fresh fruit and fresh vegetable trade: an application of the gravity model

In order to analyse the effect of exchange rate uncertainty, we apply an empirical gravity equation to two sets of US bilateral trade data: fresh fruit over the period 1976–1999 for a panel of 26 countries; and fresh vegetables over the period 1976–2006 for a panel of nine countries. Based on panel estimation methods, and using both a moving SD measure and the Perée and Steinherr (1989) measure of exchange rate uncertainty, the results show that US bilateral fresh fruit trade has been negatively affected by exchange rate uncertainty. We also find some evidence that the exchange rate between the US dollar and the currencies of Latin American trading partners accounts for most of the negative impact of exchange rate uncertainty on bilateral trade flows in fresh fruit. In contrast, when using panel estimation methods and both measures of exchange rate uncertainty, we find no statistically significant evidence for any negative effect of exchange rate uncertainty on US bilateral fresh vegetable trade. However, we do find a statistically significant negative effect for exchange rate uncertainty when we estimate a US export gravity equation for fresh vegetables using the same panel of countries.     

Does the Degree of Development Matter in the Impact of Banking Crises on International Trade?

This paper analyzes how a country's degree of economic development affects the impact of banking crises on international trade. To this end, we estimate a gravity model of trade using a sample of 139 countries over the period 1975–2012. Our results show that middle income countries are generally the most negatively affected. In contrast, financial turmoil appears to have less impact on bilateral trade flows among high income countries and, more specially, among low income nations. The level of financial development, contract enforcement, as well as the extent of the use of banking credit within international trade all help to explain our findings.     

Testing the Linkages between Trade and Productivity Growth

The authors examine the effect of trade on productivity growth using data from nine manufacturing industries across 12 OECD countries over the period 1978–97. Because causality between productivity growth and trade share runs both ways, geographical characteristics of countries are used to instrument for average bilateral trade volumes over the 20‐year period. In addition, to exploit the time‐series nature of the data, the authors construct a panel dataset and employ dynamic panel data techniques. After controlling for industry‐specific heterogeneity, the results indicate that increased exposure to trade, in particular higher import volumes, exerts a positive influence on industries' productivity growth. However, the effect is rather small.     

The GATT/WTO has promoted trade,but only in capital-intensive commodities!

This article uses gravity models to explore the impact of the General Agreement on Tariffs and Trade (GATT)/World Trade Organization (WHO) on bilateral trade in a sample of 46 countries over the period 1965 to 1997. Our data enable us to disaggregate trade by broad commodity aggregates. The results for total trade are similar to those reported by Rose (2004). However, the disaggregated estimates reveal that the GATT/WTO has had a positive and statistically significant impact on trade in capital-intensive commodities, but no statistically significant impact on trade in other commodities. The article demonstrates that simple modifications of Rose's approach lead to results that are much more ‘common sense’ than his (JEL F10, F15).     

Make Trade Not War?

This paper analyses theoretically and empirically the relationship between military conflicts and trade. We show that the conventional wisdom that trade promotes peace is only partially true even in a model where trade is economically beneficial, military conflicts reduce trade, and leaders are rational. When war can occur because of the presence of asymmetric information, the probability of escalation is lower for countries that trade more bilaterally because of the opportunity cost associated with the loss of trade gains. However, countries more open to global trade have a higher probability of war because multilateral trade openness decreases bilateral dependence to any given country and the cost of a bilateral conflict. We test our predictions on a large data set of military conflicts on the 1950–2000 period. Using different strategies to solve the endogeneity issues, including instrumental variables, we find robust evidence for the contrasting effects of bilateral and multilateral trade openness. For proximate countries, we find that trade has had a surprisingly large effect on their probability of military conflict.     

Exporting to fragile states in Africa: Firm‐level evidence

This study analyses the effect of fragility in destination markets on firm export behavior and the role of firm size in mediating adverse outcomes. The analysis is conducted using firm transaction data on Kenyan exports to Africa over the period 2004–2013. The analysis reveals that fragility negatively affects a firm's decision to enter a given destination market, reducing Kenya's bilateral trade flows to African countries. Larger firms are more resilient to destination shocks in fragility and are less likely to exit. These results are robust to alternative measures of destination fragility, and the exclusion of bordering countries and the East African Community partner states. Our analysis reveals that the effect of business fragility (regulatory quality, government effectiveness, and control of corruption) dominates that of political fragility (voice and accountability, rule of law, and political stability), although both effects are negative and significant.     

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 implications of the Euro in EMU countries: a panel gravity analysis

In this paper, we study the intra-EMU and intra-Eurozone trade effects of the euro adoption on 29 European Economic and Monetary Union countries (including 17 Eurozone economies and Iceland) from the period 1994 through 2011. We employ a generalized gravity model that controls for an extended set of trade theory and policy variables. The gravity model is estimated using the robust panel data techniques that includes times effects, besides country-specific effects. The various econometric specifications of the gravity equation, on the whole dataset of 29 economies, yield positive and significant impact (to be around 14 %) of the euro currency adoption on bilateral trade flows. Next, euro effect on bilateral trade and exports on a smaller dataset is estimated. The estimated results suggest that bilateral trade and exports increase by 20.81 and 18.57 %, respectively, when both the countries belong to the Eurozone. This effect is larger than the one obtained when only one of the two trading partners uses the euro as its currency. In addition, the validity of the assumptions of Heckscher–Ohlin (H–O) theory are checked for the countries under study. The estimated results reject the H–O theory in favor of Modern Trade theories. However, the low value of the coefficient on respective variable suggests that, over the period, the type of trade among these countries has transited from inter-industry trade to horizontal intra-industry trade. This suggests that these developed European economies are on the path of economic convergence via intra-industry trade.     

Selected MENA countries' attractiveness to G7 investors

The objective of this paper is to evaluate the relative attractiveness of seven MENA countries (Algeria, Egypt, Iran, Saudi Arabia, Morocco, Tunisia and Turkey) as a location for foreign portfolio investment (FPI) from the G7 investors' viewpoints over the period 2001-2005. We suggest a methodology based on the combination of the gravity model, the analytic hierarchy process (AHP) and the goal programming model (GP). The gravity model is used to determine the attractiveness factors of a country with respect to FPI for 30 investing and 43 receiving countries. Results show the importance of information costs and bilateral trade in the determination of the bilateral asset holdings. The AHP method is applied to prioritize the set of FPI location alternatives according to variables' significance in the gravity model outcome; information costs, bilateral trade, GDP, investment freedom, institutional quality, and geographic distance. Results show that in general Saudi Arabia is the best destination for Japanese and US investors, Turkey is the favorite location for French, German, Italian and British investors and Algeria is the preferred country for Canadian investors. A combined AHP-GP model has been used to determine the degree of portfolio investment in each MENA country from the viewpoint of G7 investors. The relative attractiveness of MENA countries varies over time and across investors. In general, over the period 2001-2005, the most attractive country is Iran for Canadian, French and Italian investors, Turkey for German and British investors and Saudi Arabia for Japanese and US investors. For a MENA country to attract more FPI it should especially improve bilateral trade and institutional quality and reduce foreign investment restrictions and information costs.     

Estimating the impact of country‐level policy restrictions on services trade

Standard techniques used to estimate gravity equations, rely on bilateral variation to identify the effect of trade barriers on bilateral trade flows. In this paper, I develop a method that estimates the effects of country‐level variables on trade between countries in the presence of firm heterogeneity and country selection into trade, a natural extension of existing empirical models of international trade. I implement the method in services data, where available measures of trade policy provide information on the average level of regulations restricting entry into a country. The results suggest that policy barriers are important determinants of services trade flows.     

Consistent Estimates of Regional Blocs' Trade Effects

This paper builds upon Feenstra (2002) to obtain consistent estimates of trade effects of regional blocs by adding bilateral effects to the gravity equation and analyzing its variation across blocs of different intensity. The results are then compared across different gravity equations used in the literature only to observe significant variation in sign, magnitude, and significance. The consequent equation shows that the effect is positive for economics cooperation agreements and preferential trade agreements, but free‐trade agreements do not have a significant incremental effect. While customs unions have a positive incremental effect over blocs of lower intensity, the incremental effect is mixed for monetary unions, and negative for economic areas and full integrations. Furthermore, the effect varies with the duration and degree of implementation as well as the coverage of blocs. Lastly, changes in trade effects of the European blocs across time observed and policy implications are discussed.     

How Reliable Are Estimations of East-West Trade Potentials Based on Cross-Section Gravity Analyses?

Gravity equations have been used repeatedly to predict the East-West trade potential since the opening-up of Eastern Europe in 1989. Most of the research in the field was done by means of cross-section data. While earlier studies indicated huge unexhausted bilateral trading potentials for the East and for the West, more recent studies have demonstrated that most of the East-West trading potential has already been consumed. In this paper, we provide insights into the prediction performance of cross section gravity equations (applied for level projections). We found rather large forecast interval spans around the predicted values. The intervals are of a size that makes any conclusions about absolute trade potentials questionable. Thus we think that cross-section gravity analysis does not permit any definite judgment as to whether actual East-West trade has already reached its potential level.
