Interconnectivity of communications networks and international trade

Abstract In this study a multi‐country model of trade is developed that captures the role of country‐specific communications network interconnectivity, which enhances trade in intermediate business services. The number of countries connected to internationally interconnected networks is found to determine the structure of comparative advantage. That is, countries with interconnected networks have a comparative advantage in the good that requires business services provided via networks. In connected countries, producers of that good benefit from the efficient transmission of business services. This research also demonstrates that countries whose country‐specific networks are not connected to the interconnected networks may become worse off as the result of trade.

Interconnectivité des réseaux de communication et commerce international Ce mémoire développe un modèle de commerce international impliquant plusieurs pays qui cerne le rôle de l'interconnectivité des réseaux de communication de chaque pays. Cette interconnectivité enrichit les flux de commerce dans les services intermédiaires d'affaires. Il appert que le nombre de pays connectés aux réseaux internationalement connectés détermine la structure de l'avantage comparatif. Ce qui veut dire que les pays qui ont des réseaux interconnectés ont un avantage comparatif dans le bien qui requiert les services d'affaires fournis par les réseaux. Dans les pays connectés, les producteurs de ces biens bénéficient de la transmission efficace de ces services d'affaires. La recherche montre aussi que les pays dont les réseaux nationaux ne sont pas connectés aux réseaux interconnectés peuvent voir leur situation s'empirer en conséquence du commerce international.     

International Service Transactions: Is Time a Trade Barrier in a Connected World?

Firms’ international fragmentation of production has recently widened its focus from outsourcing of intermediates to off-shoring of business services such as software program development and international call center networks. Although many services are intangible and non-storable, gravity model estimates show that geographical distance between business partners matters less for commercial service transactions. Rather, time zones can be a driving force of international service trade by allowing for continuous operation over a 24 hours business day (continuity effect) when a proper division of labor is feasible and countries are connected to electronic communications infrastructure (ICT). But even when ICT provides alternatives for face-to-face interaction, time zones can act as a barrier when coordination problems with sleeping business partners occur (synchronization effect). In this paper, we find empirical evidence for the continuity effect in trade of business services, which is robust to measurement and sample size. Even more important is that the effect of time zones on service trade depends on access to ICT. An improvement of ICT infrastructure will affect business service trade at long time zone distances significantly more than trade at short time zone distances.     

Time Zones as a Source of Comparative Advantage

This note proposes a three-country model of monopolistic competition that captures the role of time zones in the division of labor. The connectivity of business service sectors via communications networks (e.g. the Internet, satellite communications systems) is found to determine the structure of comparative advantage. That is, two countries with connected service sectors have a comparative advantage in the good that requires business services. It is also shown that the third unconnected country inevitably specializes in the good that does not require business services.     

SHIFT WORKING AND TRADE IN LABOUR SERVICES WITH TIME ZONE DIFFERENCES

Using a two‐factor (labour and capital), two‐good (shift‐working and non‐shift‐working commodities) model with two countries (Home and Foreign), which are located in different time zones, we highlight the impact of trade in labour services (via communications networks) on the comparative advantage of countries capable of such trade. It is shown that a comparative advantage in a shift‐working commodity is held by pairs of countries in different time zones and connected through a good communication network. Concerning factor prices, if the shift‐working commodity is capital (respectively, labour) intensive, the wage rate for day‐shift labour will decrease (respectively, increase) as a result of trade in labour services. It is also demonstrated that this labour service utilization is mutual: some of Home's day‐shift labour will be utilized for the Foreign night shift, and vice versa. Thus, periodic trade in labour services occurs across countries.

The Division and Size of Gains from Liberalization in Service Networks*

If two disjoint country service networks involving a small and large country are connected as part of international liberalization in the presence of network externalities, the per capita gain for the small country from access to a large network will be large, and the per capita gain for the large country will be small. In contrast to goods, the benefits of liberalization in network‐related services are more likely to be approximately equally divided between large and small countries than is true of trade in goods, where benefits accrue disproportionately to the small country. We also argue that non‐cooperation in network‐related services trade may involve more extreme retaliation than suggested for trade in goods by the optimal tariff literature, so that relative to a non‐cooperative outcome, gains from liberalization in network‐related services become larger than from liberalization in goods. We develop simple models which we use for numerical examples showing these points, along with an empirical implementation for global telecoms liberalization for the US, Europe, Canada, and the rest of the world using the framework developed in the paper. This shows similar proportional gains to regions, consistent with the theme of the paper that goods and services liberalization differ.     

Does trade creation by social and business networks hold in services?

Recent literature on the border effect has shown that the intensity of trade in goods is positively correlated with the migration stocks between any pair of countries/regions. The number of references for business networks is more limited, but they are also related with a reduction on information costs. In this article we investigate whether such a relation holds also for Spanish domestic trade flows in consumer services. To this end, we use a gravity model rooted in the Dixit–Stiglitz–Krugman theoretical framework and a unique data set on interregional trade flows for some of the main tourism service sectors, namely, accommodations and restaurants. Our industry-specific analysis finds a large positive effect for restaurants but a more limited effect for accommodations. Forces driving the demand in each sector explain this result and suggest the idea that although social networks can act as a substitute of firms in some sectors at the same time they can enhance trade flows in other sectors. We perform the same kind of analysis with a data set (obtained by a similar method) for domestic trade in goods and discover a different response to social and business networks. Finally, we treat the potential endogeneity by taking the instrumental-variable approach of the Poisson pseudo-maximum likelihood estimator and thus obtain consistent results.     

我国运输服务贸易发展特征及战略选择

运输服务贸易作为传统的服务贸易项目之一,我国运输服务贸易的国际地位日益提高.运输服务贸易发展呈现出贸易额快速增长、逆差显著、外资企业数量与投资额逐年上升、主要贸易伙伴为欧美韩等发达国家、运输方式以海运为主等特征.然而,交通运输业发展滞后,运力不足、运输企业规模小实力弱、对外开放度较高等因素也在制约着我国运输服务贸易的发展.因此,应从多层面制定正确的发展战略:政府层面为运输企业创造良好的发展环境、积极应对国际航运贸易壁垒、全方位发展海陆空运输业;行业层面充分发挥行业协会的作用;企业层面采取多种途径扩大运输企业规模效益、提高技术水平与服务质量、健全企业服务网络等,从而进一步促进我国运输服务贸易的快速发展.     

Liberalizing Services Trade In APEC: A General Equilibrium Analysis with Imperfect Competition

The paper studies services-sector trade liberalization in the Asia–Pacific Economic Co-operation (APEC) Forum using a global, multicountry, multisector applied general equilibrium model with an imperfectly competitive service sector. Reducing the service sector's nontariff barriers is modeled by eliminating the possibility for oligopolistic firms to price-discriminate between client countries within APEC and lowering the fixed costs of the firms doing service exporting business. The results suggest that services trade liberalization reinforces existing sectoral trade balances. Increase in demand for intermediate services tends to reinforce rather than counteract the role of primary factors in determining sectoral comparative advantage. The western APEC members received the greatest welfare gains from services trade liberalization, while the developing economies gained more if only tariffs were eliminated.     

The Distributional and Allocative Impacts of Virtual Labor Mobility across Time Zones through Communication Networks

Using a specific‐factors' model, with two goods (a shift‐working good and a non‐shift‐working good), three factors (capital specific to shift‐working, land specific to non‐shift‐working and labor) and two countries (Home and Foreign), which are located in different time zones, we highlight the impact of trade in labor services via communication networks on factor prices and production patterns. If two countries are identical in size, then under free trade in labor services, all workers work only in their local daytime, and night shift in each country is performed by imported labor services supplied by residents of the other country in their local daytime. Night‐time wage becomes the same as daytime wage (a wage equalization result). Other factor prices are also equalized. In both countries, capital rental rate increases, while land rent decreases. However, if two countries are different in size, trade in labor services does not equalize wages: in the large country, wages for night‐shift workers are higher than daytime wages and some residents work at night; in the small country, daytime wages become higher than night‐time wages and no one works at night, and night‐shift work is done by imported labor services from the large country. Land rent in the small country decreases. Land rent in the large country may or may not decrease, but it is always higher than in the small country. Capital rental rates in both countries are equalized and increase.     

Deregulation,competition, and the network size in the market for telecommunication services

This paper analyzes the networking aspect in telecommunication services and the recent divestiture and increased competitiveness of the industry. The product considered is the right to access the network. The utility of a consumer from having access to a network depends on the network's quality, defined by the number of other local and long-distance consumers which can be reached. Network services are provided in two layers; On the lower layer consumers within a local access and transport area (LATA) are connected to a central office which provides the basic switching facility for local telecommunication. On the upper layer, LATAs are connected together by an interLATA carrier, to enable long distance communication from different localities.It is shown that relative to the choices of an unconstrained monopolist, larger networks at both layers may be obtained by imposing quality controls, while price controls may have the opposite effect. A divestiture policy in which all local carriers are connected to a single long distance carrier is likely to reduce the quality of services at both layers. Introducing competition among long-distance carriers further reduces the quality of long distances services but may improve the local service.

The ECFA and its expected effect on cross-strait trade and investment: a Taiwanese perspective

To come to terms with the realization of ASEAN+1, Taiwan had concluded with mainland China a special free trade agreement (FTA), the Economic Cooperation Framework Agreement (ECFA) in June 2010. This framework agreement provides an early harvest agreement of near-term tariff elimination, including detailed product schedules for goods and services from each side, with the final shape of fuller trade liberalization in goods and services taking years to negotiate and realize. The conclusion of the ECFA has been considered as a major breakthrough in cross-strait talks and economic relationships, even though it is by no means free from controversies inside Taiwan. The authors are therefore motivated by hot debates in Taiwan to reflect on the expected trade effect of the ECFA by taking into account the factor of cross-strait global production networks. In particular, we examine with a proposed model and statistical robustness, the trend of Taiwan-based firms' localization in mainland China, driven in part by constant movements in global production networks, which generates complicated and dynamic relationships between Taiwan's investment-induced trade and structural shift in Taiwan's exports to mainland China. Based on our empirical findings, we reflect on the conventional views on the trade effect of the free trade agreement. The results of our analyses tend to support a cautious view about the trade effect of the ECFA. Without denying the significance of the ECFA and deepening cross-strait economic relationships, we argue that the impact of the ECFA should be interpreted in a wider context than just the trade perspective, as the conventional wisdom and the existing evaluations suggested.     

Connectivity in East Asia

As Asian economies have become more connected through physical and institutional infrastructure, the region's trade has grown and changed. Intraregional trade has increased its share, in large part through the expansion of trade in intermediates in connection with development of global value chains. At the same time, as part of the same process and as part of the structural transformation that underlies most economic development, the share of services in Asia's trade has risen. Policies that support the development of regional infrastructure and the flow of goods and services, as well as factors of production, can increase the benefits from connectivity. Meanwhile, regional cooperation has a key role to play in mitigating negative impacts that may arise from the vulnerabilities that accompany greater connectivity.     

Would a North-South Free Trade Agreement Hurt Unskilled Labor in the North?

I present a simple model to examine the impact of international outsourcing on the welfare of skilled and unskilled labor. In this model, specialized business services are to facilitate manufacturing production, creating additional welfare gains in the presence of positive production externalities. Policies that favor the business service sector contribute to the development of a larger bundle of specialized business services, generating more welfare gains to not only skilled but also unskilled labor. Thus, a country’s unskilled labor is not necessarily worse off with open trade if the country is prosperous in business service provisions.     

How remote is the offshoring threat?

Advances in communication technology make it possible for workers in India to supply business services to head offices located anywhere. This has the potential to put high-wage workers in direct competition with much lower paid Indian workers. Service trade, however, like goods trade, is subject to strong distance effects, implying that the remote supply of services remains limited. We investigate this proposition by deriving a gravity-like equation for service trade and estimating it for a large sample of countries and different categories of service trade. We find that distance costs are high but are declining over time. Our estimates suggest that delivery costs create a significant advantage for local workers relative to competing workers in distant countries.

Networks of knowledge among unionized firms

Abstract.  We develop a model of strategic networks in order to analyze how trade unions will affect the stability of R&D networks through which knowledge is transmitted in an oligopolistic industry. Whenever firms settle wages, the partially connected network is likely to emerge in the long run if and only if knowledge spillovers are large enough. However, when unions settle wages, the complete network is the unique stable network. In other words, the stronger the union bargaining power is, the more symmetric stable R&D networks will be. In terms of network efficiency, the partially connected network (when firms settle wages) does not Pareto dominate the complete network (when unions settle wages) and vice versa.     

The Impact of Liberalizing Trade in Services on Trade in Goods: An Empirical Investigation

In this paper we use a large dataset to explore whether the liberalization of trade in services is beneficial for the international trade in goods. We find empirical evidence supporting this notion. We investigate which types of trade in services are more important for the international trade in goods and find that trade in transportation and communication services generate the largest impacts on trade in goods. We also investigate which types of trade in goods are likely to benefit from the liberalization of trade in services and find that, under the 2‐digit ISTC classification, all the categories are likely to exhibit a positive impact.     

Bargaining and network structure: An experiment

We consider bargaining in a bipartite network of buyers and sellers, who can only trade with the limited number of people with whom they are connected. We perform an experimental test of a graph-theoretic model that yields unique predictions about equilibrium prices for the networks in our sessions. The results diverge sharply depending on how a connection is made between two separate simple networks, typically conforming to the theoretical directional predictions. Payoffs can be systematically affected even for agents who are not connected by the new link, and we find evidence of a form of social learning.
