One objective of government investment is to develop public infrastructure which may reduce private sector costs. In a developing economy, the scope for payoffs to investments of this sort may be particularly large. A major concern related to the recent fiscal adjustment in Mexico is that it has been carried out, in part, by depleting public infrastructure stocks.We estimate the effects of public infrastructure on private sector costs in Mexico and calculate the implied optimal infrastructure stocks. Our estimates indicate that previous results suggesting a large productive role of public infrastructure capital are not robust. There is little evidence that public infrastructure plays a large role in reducing private sector costs.
"Policy-makers often call for expanding public spending on infrastructure, which includes a broad range of investments from roads and bridges to digital networks that will expand access to high-speed broadband. Some point to near-term macro-economic benefits and job creation, others focus on long-term effects on productivity and economic growth. This volume explores the links between infrastructure spending and economic outcomes, as well as key economic issues in the funding and management of infrastructure projects. It draws together research studies that describe the short-run stimulus effects of infrastructure spending, develop new estimates of the stock of U.S. infrastructure capital, and explore the incentive aspects of public-private partnerships (PPPs). A salient issue is the treatment of risk in evaluating publicly-funded infrastructure projects and in connection with PPPs. The goal of the volume is to provide a reference for researchers seeking to expand research on infrastructure issues, and for policy-makers tasked with determining the appropriate level of infrastructure spending"--

Microeconometric analysis of Mexican industry shows additional investment in public infrastructure produces only a small increase in output. This suggests that the policy emphasis in Mexico should be on the better upkeep of existing infrastructure to ensure the continuity of public services rather than on new capital investment.
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.
Essential to anyone involved in the planning, design, construction, operation, or finance of infrastructure assets, this innovative work puts project delivery, finance, and operation together in a practical new formulation of how public and private owners can better manage their entire collection of infrastructure facilities.
Governments have long recognized the vital role that modern infrastructure services play in economic growth and poverty alleviation. For much of the post-Second World War period, most governments entrusted delivery of these services to state-owned monopolies. But in many developing countries, the results were disappointing. Public sector monopolies were plagued by inefficiency. Many were strapped for resources because governments succumbed to populist pressures to hold prices below costs. Fiscal pressures, and the success of the pioneers of the privatization of infrastructure services, provided governments with a new paradigm. Many governments sought to involve the private sector in the provision and financing of infrastructure services. The shift to the private provision that occurred during the 1990s was much more rapid and widespread than had been anticipated at the start of the decade. By 2001, developing countries had seen over $755 billion of investment flows in nearly 2500 infrastructure projects. However, these flows peaked in 1997, and have fallen more or less steadily ever since. These declines have been accompanied by high profile cancellations or renegotiations of some projects, a reduction in investor appetite for these activities and, in some parts of the world, a shift in public opinion against the private provision of infrastructure services. The current sense of disillusionment stands in stark contrast to what should in retrospect be surprise at the spectacular growth of private infrastructure during the 1990s.
