Book Description
"Of the major kinds of physical infrastructure, electricity generating capacity has roughly the same marginal productivity as physical capital as a whole. So have roads-plus-rail, globally and in lower-income countries. Telephones, however, and transport routes in higher-income countries, have higher marginal productivity than other kinds of capital"--Cover.

Book Description
Of the major kinds of physical infrastructure, electricity generating capacity has roughly the same marginal productivity as physical capital as a whole. So have roads-plus-rail, globally and in lower-income countries. Telephones, however, and transport routes in higher-income countries, have higher marginal productivity than other kinds of capital.Using panel data for a cross-section of countries, Canning estimates an aggregate production function that includes infrastructure capital. He finds that:middot; The productivity of physical and human capital is close to the levels suggested by microeconomic evidence on their private returns.middot; Electricity generating capacity and transportation networks have roughly the same marginal productivity as capital as a whole.middot; Telephone networks appear to show higher marginal productivity than other types of capital.Panel data cointegration methods used in estimation take account of the nonstationary nature of the data, are robust to reverse causation, and allow for different levels of productivity and different short-run business-cycle and multiplier relationships across countries.This paper - a product of Public Economics, Development Research Group - is part of a larger effort in the group to study the impact of public expenditures. The study was funded by the Bank's Research Support Budget under the research project Infrastructure and Growth: A Multicountry Panel Study (RPO 680-89). The author may be contacted at

Book Description
This paper reviews the linkages between infrastructure and economic development based on both formal empirical research and informal case studies. The main thesis is that economic benefits result from investments in infrastructure only to the extent that they generate a sustainable flow of services valued by consumers. Thus, an analysis of infrastructures' contributions to growth must look at the impacts of services as actually perceived, not at indirect indicators that measure only aggregate provision of infrastructure capital. The paper notes that macro and industry level research , although having its limitations, suggest a positive and statistically significant relationship between infrastructure and economic output. However the conclusions derived from this research (most of which derives from developed countries) provide little specific guidance for policy. To gain more practical insights about how infrastructure contributes to economic growth and to improved quality of life, and to understand the welfare costs of inadequate or unreliable infrastructure, it is necessary to look at microeconomic evidence. Particularly interesting illustrations of these relationships are to be found in developing countries where there is wide variance in the availability and quality of infrastructure.

Book Description
This Round Table addresses the macroeconomic effects of transport infrastructure policies, and aimed at identifying tools that could determine the overall volume of public expenditure for transport infrastructure investment. It also identifies methods for assessing macroeconomic impact.

Book Description
The book examines the complex relationships between infrastructure and the rest of the economy. In particular, it focuses on the contentious issue of whether infrastructure investments stimulate productivity growth, issues of pricing and ownership, and also development problems such as environmental damage. Methods range from traditional production function models and compensating variation approaches to nonlinear methods of dynamic analysis. There is a unique emphasis on the ability of these different methods to allow for the complex interdependencies involved. Six of the fifteen papers deal with these methodological aspects, whereas the remainder addresses specific cases or examples in a variety of countries (Europe, USA and developing countries).

Book Description
Using panel data models, the author examines the threshold effects of the productivity of infrastructure investment in developing countries. He considers various specifications of an augmented production function that allow for endogenous thresholds. More precisely, these specifications are tested in a panel threshold regression model. The author's main robust result is the presence of strong threshold effects in the relationship between output and private and public inputs. Whatever the transition mechanism used, the testing procedures lead to strong rejection of the linearity of this relationship. In particular, the productivity of infrastructure investment generally exhibits some network effects. When the available stock of infrastructure is very low, investment in this sector has the same productivity as noninfrastructure investment. On the contrary, when a minimum network is available, the marginal productivity of infrastructure investment is generally largely greater than the productivity of other investment. Finally, when the main network is achieved, its marginal productivity becomes similar to the productivity of other investment.

Book Description
Abstract: This paper presents a survey of recent research on the economics of infrastructure in developing countries. Energy, transport, telecommunications, water and sanitation are considered. The survey covers two main set of issues: the linkages between infrastructure and economic growth (at the economy-wide, regional and sectoral level) and the composition, sequencing and efficiency of alternative infrastructure investments, including the arbitrage between new investments and maintenance expenditures; OPEX and CAPEX, and public versus private investment. Following the introduction, section 2 discusses the theoretical foundations (growth theory and new economic geography). Section 3 assesses the analysis of 140 specifications from 64 recent empirical papers-examining type of data used, level of aggregation, econometric techniques and nature of the sample-and discusses both the macro-econometric and micro-econometric contributions of these papers. Finally section 4 discusses directions for future research and suggests priorities in data development.
