Does the internet defy the law of gravity?

We show that gravity holds in the case of digital goods consumed over the Internet that have no trading costs. Therefore trade costs cannot fully account for the effects of distance on trade. In particular, we show that Americans are more likely to visit websites from nearby countries, even controlling for language, income, immigrant stock, etc. Furthermore, we show that this effect only holds for taste-dependent digital products, such as music, games, and pornography. For these, a 1% increase in physical distance reduces website visits by 3.25%. For non-taste-dependent products, such as software, distance has no statistical effect.     

On the conservation of distance in international trade

Using disaggregated bilateral trade data, we find that the elasticity of trade to distance increased (in absolute value) by about 10% since 1985. To explore the reasons for this shift, we decompose the change in the distance elasticity of trade into the part due to a shift in the composition of trade among industries and the part due to a change in the distance sensitivity within industries. We find that adjustment in the composition of trade had little effect, but for 40% of industries distance became more important, with nearly all of the remaining industries showing no significant change. We explore alternative hypotheses as to why the elasticity of trade to distance increased in some industries. We find that homogeneous goods, bulky goods, and high tariff goods became significantly more distance sensitive. In contrast, the evidence implies that changes in tariffs and freight costs have reduced the importance of distance on trade. We conclude that the increase in the importance of distance over time is related to the substitutability of goods and the level of trade costs, but not to changes in tariffs or freight costs.     

Transport costs and trade: Empirical evidence for Latin American imports from the European union

Abstract

This paper aims to investigate the relationship between trade flows and transport costs. In previous studies the cost of transport was considered as an exogenous variable. However, an expanding volume of trade also reduces the unit cost of transport and, therefore, the causal relationship between trade and transport costs may be operating in both directions. A transport-costs equation is estimated using data on transportation costs from the International Transport Data Base (BTI). The relationship between transport costs and trade is then analysed by applying a gravity model for sectoral imports for five Latin American Countries from the European Union. We investigate the endogeneity of the transport cost and trade variables by estimating simultaneously both equations. Our results show that, while higher distance and poor importer's infrastructure notably increase transport costs, a higher volume of trade has the opposite effect. Moreover, trade is significantly deterred by higher transport costs and fostered by cultural similarities.     

Interacting factor endowments and trade costs: A multi-country, multi-good approach to trade theory

We provide a synthetic analysis of the different ways in which countries participate in the world economy. Classic trade questions are reconsidered by generalizing a factor-proportions model to multiple countries, multiple goods or multi-stage production, and country-specific trade costs. Each country's production specialization, trade and welfare is determined by the interaction between its relative endowment and its trade costs. We consider the effects of allowing one good to ‘fragment’ into component and assembly production. The volume of trade and welfare levels are higher with fragmentation for most countries, although for many countries these variables fall with fragmentation.     

Exchange rates and US direct investment into Latin America

Abstract

In this paper, we analyze separately the determinants of maritime transport and road transport costs for Spanish exports to Poland and Turkey (markets for which maritime and road transport are competing modes) and investigate the different effects of these costs on international trade. First, we investigate the extent to which maritime and road transport costs depend on different factors such as unit values, distances, transport conditions, service structures, and service quality. Second, we analyze the relative importance of road and maritime transport costs in comparison with distance measures as determinants of trade flows. The main results of this investigation indicate that real distance is not a good proxy for transportation costs and identify the central variables influencing road and maritime transportation costs: for both modes, transport conditions are strong determinants, whereas efficiency and service quality are more important for maritime transport costs, and geographical distance is more important for road transport. Road and maritime transport costs are central explanatory factors of exports and they seem to deter trade to a greater extent than road or maritime transit time when endogeneity is considered.     

Cooperative and non-cooperative R&D and trade costs

We examine the effect of trade liberalization on the level and mode of R&D in an international duopoly setting. Firms have the choice to invest in R&D either independently or cooperatively. A reduction in trade cost increases R&D irrespective of the mode of R&D. However, an increase in spillovers has ambiguous effects on R&D. More precisely, we find that an increase in spillover leads to higher R&D activity under cooperation but lower R&D activity under non-cooperation. Concerning cooperation versus non-cooperation, we find that firms prefer cooperation only if trade costs are low. Consumers are better off under cooperation if spillovers are high. We find that there can be a mismatch between private and social incentives. If spillovers are low and trade costs are low then cooperation might be privately profitable but socially undesirable. On the other hand, if there are large spillovers and high trade costs then cooperation may be socially desirable but not privately profitable.     

Investment liberalization and international trade

This paper estimates the cross-price elasticity of exports with respect to investment costs for bilateral relations between 36 countries. We show that the effect of reducing foreign direct investment costs on exports depends on country characteristics and trade costs as predicted by the [Markusen, 1997] and [Markusen, 2002] model. When countries differ in relative factor endowments and trade costs are low, investment liberalization stimulates exports, whereas when countries are similar in terms of relative factor endowments and size, and trade costs are moderate to high, investment liberalization reduces exports.

International business complexity and the internationalization of languages

While the impacts of culture on international trade and foreign direct investment (FDI) have been much discussed, the influence of languages has been underappreciated in international business. We address this paucity by integrating literature from international economics, international business, Chinese business history, and linguistics to examine the transaction costs of languages. While we recognize that languages represent both a tool in international economic transactions and a vehicle to transmit cultural values, our results point out that this tool is employed differently in international trade and in FDI. Communication costs for both FDI and international trade show a hierarchy, with English the most inexpensive among major trade languages; however, we find that communication costs are much more important in FDI than in international trade. Herein, we offer practical suggestions corporations may implement regarding the matter.     

Geographical disadvantage: a Heckscher-Ohlin-von Thünen model of international specialisation

We analyse the trade and production patterns of countries located at varying distances from an economic centre. Exports and imports of final and intermediate goods bear transport costs which increase with distance. We show how production and trade depend on factor endowments and factor intensities, and also on countries’ locations and the transport intensities of different goods. Countries divide into zones with different trade patterns, some export oriented and others import substituting. We study the implications of distance for factor prices and real incomes, the effects of changes in transport costs, and the locational choice of new activities.     

Do falling iceberg costs explain recent U.S. export growth?

We study empirically and theoretically the growth of U.S. manufacturing exports from 1987 to 2007. We use plant-level data on exporters' export intensity to identify the changes in iceberg costs over this period. Given this change in iceberg costs, we find that a GE model with heterogeneous establishments and dynamic exporting decision from a sunk cost of starting to export is consistent with both aggregate U.S. export growth and the changes in the number and size of U.S. exporters. The model also captures the gradual response of U.S. exports to the cut in iceberg costs. A model with a static exporting decision generates substantially less trade growth and misses out on the timing of export growth. We also study the interplay between changes in the structure of manufacturing and trade. We find that the growth in trade contributed little to the contraction in U.S. manufacturing while changes in the structure of manufacturing from changes in sectoral productivity, capital intensity, idiosyncratic shocks, and corporate taxation reduced U.S. export growth by as much as 10%.     

Beyond the Information Technology Agreement: Harmonisation of Standards and Trade in Electronics

Product standards can have a dual impact on costs and, thus, on trade. They can impose costs on exporters as it may be necessary to adapt products for specific markets (cost effect). In contrast, standards can reduce exporters’ information costs as they convey information on product characteristics (informational effect). Using a new World Bank database of European standards for electronic products, we examine the net impact of internationally harmonised European standards on European Union imports. We find that European Union standards for electronic products that are harmonised to international standards have a significant and a positive net effect on trade. The results suggest that efforts to promote trade in electronic products could be complemented by steps to promote standards harmonisation. This might include, for example, restarting talks to extend the WTO’s Information Technology Agreement to commitments to harmonise national standards in electronic products.     

Trade barriers and trade flows with product heterogeneity: An application to US motion picture exports

We extend Melitz (2003) to allow for both global and bilateral fixed export costs. If global (bilateral) export costs dominate, the average sales ratio (import sales per product variety/domestic sales per variety), decreases (increases) in variable (fixed) trade barriers, due to adjustment along the intensive (extensive) margin of trade. Using novel data on bilateral US movie exports we find that (i) variation in box-office revenues per movie is much larger than in the number of movies exported, and (ii) the average sales ratio decreases in geographic and linguistic distance. These findings suggest that global fixed export costs dominate.     

Buyer-seller relationships in international trade: Evidence from U.S. States' exports and business-class travel

International trade has become increasingly dependent on the transmission of complex information, often realized via face-to-face communication. This paper provides novel evidence for the importance of in-person business meetings in international trade. Interactions among trade partners entail a fixed cost of trade, but at the same time they generate relationship capital, which adds bilateral specific value to the traded products. Differences in the face-to-face communication intensity of traded goods, bilateral travel costs and foreign market size determine the optimal amount of interaction between trade partners. Using U.S. state level data on international business-class air travel as a measure of in-person business meetings, I find robust evidence that the demand for business-class air travel is directly related to volume and composition of exports in differentiated products. I also find that trade flows in R&D intensive manufactures and goods facing contractual frictions are most dependent on face-to-face meetings. The econometric identification exploits the cross-state variation in bilateral exports and business-class air travelers by foreign country and time period, circumventing any spurious correlation induced by cross-country differences driving aggregate travel and trade patterns.     

Internationalisation, industrial policy and clusters

This paper analyses industrial policy in an open economy hosting an agglomeration consisting of vertically linked upstream and downstream firms. We show that optimal policy towards upstream and downstream industries may typically differ radically in this setting as compared to the case of a closed economy. Internationalisation in terms of international mobility of firms as well as reduced trade costs is found to have significant impact on policy design. We find that in addition to technology and demand characteristics, degree of mobility and level of trade cost are key determinants of tax and subsidy levels.

Trade and the location of industries: Some new results

We study a two-country two-sector model with free entry and monopolistic competition where both industries use labour to produce differentiated goods. The two countries are identical except for size. Labour is freely mobile across industries but it cannot move internationally. Transport costs affect both industries. The location of industries and the pattern of trade are the results of the interaction of two effects: the home market effect and the wage differential effect. The main results are: (i) if the two countries are sufficiently close in size and demand elasticities differ across industries (transport costs being equal), a continuous fall in transport costs from a prohibitive level to zero is associated with a reversal in the pattern of trade at some intermediate level. For large transport costs, the large country is a net exporter of the more differentiated good. For lower transport costs, the large country becomes a net exporter of the less differentiated good; (ii) if the two countries are very different in size and demand elasticities differ across industries (transport costs being equal), the larger country is always a net exporter of the less differentiated good.

Network externalities,transport costs,and tariffs

This article formulates a reciprocal market model of international duopoly with network externalities to reconsider welfare effects of reductions in transport costs and tariffs. Depending on the magnitude of network externalities, we show two possibilities. One of them, which emerges under strong network externalities, illustrates that freer trade unambiguously improves welfare for any initial level of trade barriers. This finding provides an affirmative evaluation of freer trade.     

DOES HYSTERESIS OCCUR IN TRADE? SOME EVIDENCE FOR BILATERAL EXPORT FLOWS AT A DISAGGREGATED LEVEL

This article shows that hysteresis effects can be specific to certain commodities and/or to trade with particular countries. We perform two tests to investigate two different implications of the hysteresis hypothesis. The first implication is that the relative price elasticity of demand for exports rises when a market becomes more competitive. The second implication is that relative export prices are insensitive to changes in the exporter's relative exchange rate. We find that hysteresis is not an insignificant phenomenon for some specific goods. Out of 14 products we can accept Baldwin's hysteresis hypothesis for three: manufacture of drugs and medicines, manufacture of office computing and accounting machinery, and manufacture of radio, television, and communication equipment. These are sectors with higher than average sunk costs in terms of advertising expenditure.
