Los costos de transporte son una de las más importantes fuentes de barreras al comercio. Inspirados por este aspecto, utilizamos un modelo empírico ad-hoc con el fin de examinar los posibles determinantes de los costos de transporte. Utilizando una base de datos de costos de transporte bilaterales para el año 1990, replicamos el trabajo de Limao y Venables (2001) y encontramos que el efecto de su ´índice de infraestructura sobre los costos de transporte no es robusto. Siguiendo a Micco (2004) y Micco y Serebrinzky (2005) calculamos dos ´índices alternativos de infraestructura. Utilizando estos ´índices encontramos que aparte de la distancia, la infraestructura, la estabilidad política, las relaciones bilaterales comunes y los acuerdos de cielos abiertos son otros importantes canales mediante los cuales los costos de transporte pueden reducirse.

In the UK, public expenditure on transport infrastructure is nearly £6 billion for the past few years. Over £500 million per year were spent on bridge assessment and strengthening and reducing the backlog of road requiring maintenance. A further £200 million a year will be spent on keeping the safe operation of the network and efficiently through day to day maintenance, lighting and signing . The Department of Transport is planning to extend private sector experience in road management and operation by introducing Design, Build, Finance and Operate (DBFO) This paper investigates the different ways of financing road transport infrastructure including road pricing, private finance in transport infrastructure, the role of the private sector, Design, Build, Finance and Operate (DBFO) schemes, the benefits and problems of such schemes. The paper considers planning gain as a means of financing transport infrastructure with examples of developers to fund link road building and improvements to the local planning system

Gross domestic product (GDP) is generally considered as the most important index and comprehensive measure of the size of economy. This paper investigates empirically the relationship between transport infrastructure (focus on highways) and GDP growth based on a production function approach. The physical stocks of transport infrastructure were used instead of monetary data to measure public capital together with several other variables (labor and private capital) that were hypothesized to affect economic growth. Then we explore a number of subsequent studies that use panel data covering the period between 1992 and 2004. An investigation was done to compare developed countries and developing countries. Results indicate that physical units are positively and significantly related to economic growth. Furthermore there was an interesting finding that the output elasticity with respect to physical units for developed countries is higher than developing countries.

A vision of the role played by infrastructure, transport and related services in the development of competitiveness and productivity is fundamental for proposing public policies linked to productive development. In particular, the supply costs and the quality of public utility and transport services are extremely relevant to countries’ productivity, GDP growth and competitiveness, and also for the development and economic integration of Latin America.

This edition of the FAL Bulletin presents a summary of the major outcomes of the workshop, “Toward an integrated transport policy: institutions, infrastructure and logistics”, which was organized by the ECLAC Infrastructure Services Unit, in late 2009. The objective of the event was to analyse the various government bodies involved in the transport sector, Chile’s experience in formulating transport policy and the challenge that formulating and executing integrated policies entails.

This edition of the FAL Bulletin summarizes the principal contributions by ECLAC and its Infrastructure Services Unit to creating and strengthening transport service infrastructure institutions in Latin America and the Caribbean. The examination is based on a bibliography of key documents issued by ECLAC since it was founded, on studies conducted by the Infrastructure Services Unit and on FAL Bulletins from the past 15 years.

The development of the agricultural area in central and northern Argentina was analysed in a recent ECLAC study. More than 80% by volume of the country's agricultural exports pass through the ports in this area. Exports by the agroindustrial complex account for 58% of the total value of Argentine sales.It is known that investments in infrastructure generally help to reduce the costs of enterprises and to enhance productivity. The main idea presented in this study is that investments in transport infrastructure are a necessary condition for the productive development of a region, especially in relation to external trade through ports and navigable waterways.In the case of Argentina, a positive relationship has been observed between the development of port and waterway services (with reduced costs and operating times, improved reliability and new services), and expansion of the agricultural border, growth of productivity and agricultural production, and its industrialization.
