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).

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.
The paper investigates empirically the determinants of economic growth for a large sample of sub-Saharan African countries during 1981-92. The results indicate that (i) an increase in private investment has a relatively large positive impact on per capita growth; (ii) growth is stimulated by public policies that lower the budget deficit in relation to GDP (without reducing government investment), reduce the rate of inflation, maintain external competitiveness, promote structural reforms, encourage human capital development, and slow population growth; and (iii) convergence of per capita income occurs after controlling for human capital development and public policies.
Public spending on infrastructure plays an important role in promoting economic growth and poverty alleviation. Empirical studies unequivocally show that under-investment in infrastructure limit economic growth. At the same time, numerous other studies have shown that investment in infrastructure can be a highly effective tool in fighting poverty reduction1. In that context, the financing of infrastructure has been a critical element of most economic growth and poverty reduction strategies in developing countries, since the start of this millennium. This book provides a comparative analysis of the aggregate and sectoral implications of higher spending on infrastructure in three very different Asian countries: China, Pakistan, and the Philippines. Particular attention is paid to the role of alternative financing mechanisms for increasing public infrastructure investment, namely distortionary and non-distortionary means of financing. The book will be of interest to scholars and policy-makers concerned with economic growth in developing countries.
Abstract: This paper provides an overview of the various channels through which public infrastructure may affect growth. In addition to the conventional productivity, complementarity, and crowding-out effects typically emphasized in the literature, the impact of infrastructure on investment adjustment costs, the durability of private capital, and the production of health and education services are also highlighted. Effects on health and education are well documented in a number of microeconomic studies, but macroeconomists have only recently begun to study their implications for growth. Links between health, infrastructure, and growth are illustrated in an endogenous growth model with transitional dynamics, and the optimal allocation of public expenditure is discussed. The concluding section draws implications of the analysis for the design of strategies aimed at promoting growth and reducing poverty.
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.
The history of China dates back thousands of years, with periods of decline followed by periods of growth and innovation. This book puts the last 50 years – China's most recent period of growth – into perspective. It explores the changing national and international connections within China and between China and other parts of the world, and their importance for understanding the past, current, and future developments of the Chinese economy. The book brings together leading international contributors from China, Japan and Europe to consider the historical developments of these connections, the importance of natural and man-made connections for the Chinese economy, the role of institutions and policies for understanding the connections and their sustainability. This book will be of interest to scholars and researchers focusing on China, economics, geography or international trade.
Over the 1980s and 1990s, most Latin American countries witnessed a retrenchment of the public sector away from infrastructure provision and an opening up of infrastructure activities to the private sector. This book analyzes the consequences of these policy changes from two perspectives. First, it reviews in a comparative framework the major trends in infrastructure provision in Latin America over the last two decades. Second, it evaluates the implication of these trends for economic growth and public deficits in the region. The book shows that in most countries private participation did not fully offset the public sector retreat. The result was a slowdown in infrastructure accumulation, which entailed a significant growth cost and weakened the intended impact of the infrastructure spending cuts on public sector insolvency.
