Geographical factors and transport infrastructure are two of the key determinants that influence international competitiveness. In this sense, the quality of such infrastructure and how widespread it is, the distribution and capacity of logistics facilities in a country, as well as the number of private operators and their degree of specialisation, all play an increasingly important role in the design of business strategies aimed at increasing a country's share of the international market. Until recently, however, availability and access to logistics services have been considered secondary factors when defining business competitiveness. This paper estimates an augmented gravity model of trade that specifically includes logistics and transport infrastructure indicators as explanatory variables. The model is estimated by using bilateral exports from 19 Spanish regions to 64 destinations (45 countries and 19 Spanish regions) with data for the period 2003 to 2007. The findings show that logistics is indeed important for the analysis of trade flows in goods and they highlight the importance of logistics measures at the regional level. In particular, the number, size and quality of logistics facilities positively influence export flows.

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.Transport costs, trade, infrastructure, imports sectors,

This paper aims to investigate the determinants of maritime and overland transport costs and the role they play in deterring trade across countries. We estimate a transport cost function using data on maritime and overland transport of the ceramic sector (tiles) obtained from interviews held with Spanish logistics operators. We also study the relationship between transport costs and trade and estimate an import demand model for ceramic products. Additionally, we present a discussion on the sensitivity of trade flows and transportation costs to the existence of back-hauling, special conditions for transport and number of reloads.1 The study of modal transport (overland versus maritime) and its differential characteristics are of relevant interest for maritime economists and should be taken into account in economic policy-making. Furthermore, the proven impact of infrastructure on transport costs and trade points towards the importance of investing in new port infrastructures as a way of fostering trade and income. Our results from the transport cost estimation show that higher distance and poor partner infrastructure lead to a notable increase in transport costs. Inclusion of infrastructure measures improves the fit of the regression, thus corroborating the importance of infrastructure in determining transport costs. The distance coefficient remains significant and with similar magnitude when we add infrastructure variables. Our results from the trade equation estimation show that importer income, as expected, has a positive influence in bilateral trade flows. Higher transport costs significantly deter trade, and distance does not appear to be a good proxy for transport costs in the ceramics sector.

This article aims to analyse the determinants of transport costs and to investigate their influence in international trade with a sample of disaggregate trade data. First, we estimate a transport-cost function using cross-section data on maritime and overland transport for four sectors: agro-industry, ceramic tiles, motor vehicle parts and accessories, and electrical and mechanical household appliances, obtained from interviews held with Spanish exporters and logistics operators in 2001.Second, we study the relationship between transport costs and trade and estimate the elasticity of trade with respect to transport costs for each sector. Important differences for high value-and low value-added sectors are observed. The trade-equation estimation shows that higher transport costs significantly deter trade, especially in high value-added sectors.
