"The median landlocked country has only 30 percent of the trade volume of the median coastal economy. Halving transport costs increases that trade volume by a factor of five. Improving the standard of infrastructure from that of the bottom quarter of countries to that of the median country increases trade by 50 percent. Improving infrastructure in Sub-Saharan Africa is especially important for increasing African trade"--Cover.

The median landlocked country has only 30 percent of the trade volume of the median coastal economy. Halving transport costs increases that trade volume by a factor of five. Improving the standard of infrastructure from that of the bottom quarter of countries to that of the median country increases trade by 50 percent. Improving infrastructure in Sub-Saharan Africa is especially important for increasing African trade.Limao and Venables use three different data sets to investigate how transport depends on geography and infrastructure. Landlocked countries have high transport costs, which can be substantially reduced by improving the quality of their infrastructure and that of transit countries.Analysis of bilateral trade data confirms the importance of infrastructure. Limatilde;o and Venables estimate the elasticity of trade flows with regard to transport costs to be high, at about -2.5. This means that:middot; The median landlocked country has only 30 percent of the trade volume of the median coastal economy.middot; Halving transport costs increases the volume of trade by a factor of five.middot; Improving infrastructure from the 75th to the 50th percentile increases trade by 50 percent.Using their results and a basic gravity model to study Sub-Saharan African trade, both internally and with the rest of the world, Limao and Venables find that infrastructure problems largely explain the relatively low levels of African trade.This paper - a product of Trade, Development Research Group - is part of a larger effort in the group to investigate the effects of geography on economic performance.

"What effect does distance have on costs for economies at different locations? Exports and imports of final and intermediate goods bear transport costs that increase with distance. Production and trade depend on factor endowments and factor intensities as well as on distance and the transport intensities of different goods"--Cover.

Afghanistan is a landlocked country which relies heavily on the road and air transport sub sector. The country mountain terrains, low quality infrastructure, and artificial and institutional barriers to trade add to geographical disadvantage of Afghanistan, and increased the cost of moving goods internationally. Pakistan and Iran provide Afghanistan the most direct route to the sea and international market through the ports of Karachi and Bandar Abbas respectively. In compare to Iran Pakistan has the most advantageous position in Afghan transit trade, by offering the most nearest route to international market through Karachi seaport. The fundamental object of this present research is to measure the geographical disadvantage of Afghanistan, and to estimate the total trucking cost between Afghanistan and Pakistan, and to indicate how distance, infrastructure, time, bribe, and geography increase the transport costs.

Much of the analysis of infrastructure's impact on trade costs focuses on conditions in developed countries. This book makes an invaluable contribution to our understanding by examining the situation in developing Asia, the world's most populous and fastest growing region. This study analyzes and draws policy implications from infrastructure's central role in lowering Asia's trade costs. Infrastructure is shown to be a cost-effective means of lowering trade costs and thereby promoting regional growth and integration. This book combines thematic and country studies, while breaking new ground in.

When in 1989 the authors started research on infrastructure, they did not foresee that this would lead to a long-term involvement in this area. Our beginning happened to coincide with the publication of David Aschauer's article on public capital and productivity, which induced a large flow of publications in this field. Infrastructure has indeed been a hot topic in policy and research during the past decade. It is surprising, however, that the number of monographs on spatial and economic impacts of infrastructure has remained very limited. The aim of this book is to contribute to the literature in a consolidated way. A distinguishing feature of our book is that we analyze infrastructure impacts using various methods (both modelling and non-modelling) at a variety of spatial levels (from local to international). Other special features are that we make ample use of 'accessibility' as a bridge concept between the areas of infrastructure and the economy. Finally, we not only treat transport infrastructure projects as given, as is the usual approach in infrastructure impact research, but we also analyze the factors influencing infrastructure supply. We have adopted a mainly non-technical approach throughout most of the book. This means that it can also be used by readers without a strong back ground in statistics, modelling or micro-economics.

Mobility is fundamental to economic and social activities such as commuting, manufacturing, or supplying energy. Each movement has an origin, a potential set of intermediate locations, a destination, and a nature which is linked with geographical attributes. Transport systems composed of infrastructures, modes and terminals are so embedded in the socio-economic life of individuals, institutions and corporations that they are often invisible to the consumer. This is paradoxical as the perceived invisibility of transportation is derived from its efficiency. Understanding how mobility is linked with geography is main the purpose of this book. The third edition of The Geography of Transport Systems has been revised and updated to provide an overview of the spatial aspects of transportation. This text provides greater discussion of security, energy, green logistics, as well as new and updated case studies, a revised content structure, and new figures. Each chapter covers a specific conceptual dimension including networks, modes, terminals, freight transportation, urban transportation and environmental impacts. A final chapter contains core methodologies linked with transport geography such as accessibility, spatial interactions, graph theory and Geographic Information Systems for transportation (GIS-T). This book provides a comprehensive and accessible introduction to the field, with a broad overview of its concepts, methods, and areas of application. The accompanying website for this text contains a useful additional material, including digital maps, PowerPoint slides, databases, and links to further reading and websites. The website can be accessed at: http://people.hofstra.edu/geotrans This text is an essential resource for undergraduates studying transport geography, as well as those interest in economic and urban geography, transport planning and engineering.

Good infrastructure is essential for socio-economic growth and sustainable development. Safe and accessible water supplies, reliable energy, good transport networks and communications technology are all vital to a region’s development agenda. This book presents a comprehensive exploration of the state of infrastructure in Africa and provides an integrated analysis of the challenges the sector faces, based on extensive fieldwork across the continent. Contributors with a wide range of expertise challenge current policy, practice and thinking on issues including the politics of infrastructure development, social inclusion, domestic resource mobilisation and infrastructure financing. The book will be an important resource for academic researchers, students and early career development professionals as well as policymakers and NGOs engaged in dialoguing the infrastructure development options for Africa.
