    Rethinking Infrastructure in Latin America and the Caribbean: Spending Better to Achieve More
    (World Bank, Washington, DC, 2017-07-18) Fay, Marianne ; Andres, Luis Alberto ; Fox, Charles ; Narloch, Ulf ; Straub, Stephane ; Slawson, Michael
    Latin America and the Caribbean (LAC) does not have the infrastructure it needs, or deserves, given its income. Many argue that the solution is to spend more; by contrast, this report has one main message: Latin America can dramatically narrow its infrastructure service gap by spending efficiently on the right things. This report asks three questions: what should LAC countries’ goals be? How can these goals be achieved as cost-effectively as possible? And who should pay to reach these goals? In doing so, we drop the ‘infrastructure gap’ notion, favoring an approach built on identifying the ‘service gap’. Benchmarking Latin America in this way reveals clear strengths and weaknesses. Access to water and electricity is good, with the potential for the region’s electricity sector to drive competitive advantage; by contrast, transport and sanitation should be key focus areas for further development. The report also identifies and analyses some of the emerging challenges for the region—climate change, increased demand and urbanization—that will put increasing pressure on infrastructure and policy makers alike. Improving the region’s infrastructure performance in the context of tight fiscal space will require spending better on well identified priorities. Unlike most infrastructure diagnostics, this report argues that much of what is needed lies outside the infrastructure sector – in the form of broader government issues—from competition policy, to budgeting rules that no longer solely focus on controlling cash expenditures. We also find that traditional recommendations continue to apply regarding independent, well-performing regulators and better corporate governance, and highlight the critical importance of cost recovery where feasible and desirable, as the basis for future commercial finance of infrastructure services. Latin America has the means and potential to do better; and it can do so by spending more efficiently on the right things.

    Rising Incomes and Inequality of Access to Infrastructure among Latin American Households
    (World Bank, Washington, DC, 2017-02) Fay, Marianne ; Straub, Stephane
    This paper documents access to services and ownership of infrastructure-related durables in the water, energy, telecom, and transport areas, based on harmonized household survey data covering 1.6 million households in 14 Latin American countries during 1992 to 2012. The paper provides a systematic disaggregation of access and ownership rates at different levels of income and over time, and econometrically derives the country infrastructure premium, a measure of how much a household benefits from simply being located in a given country. The results show extensive inequality of access, within countries across the income distribution, but also across countries for households at similar levels of income. For water and electricity, for example, up to two-thirds of the variability in individual percentile access to infrastructure services and consumption of related assets can be explained by country residence only. In addition, few country fundamentals appear to be significant in explaining this variability, pointing to policy differences as an important determinant. The paper derives the income elasticity of infrastructure access for the full set of indicators, and uses these to estimate the time that would be needed to close the remaining gap for households at different levels of the income distribution under a "business as usual" hypothesis. Under that scenario, universal access appears to be decades away for many countries in the region. The last part discusses the policy challenges, arguing that in a context in which public budgets face strong constraints and significant increases in private investment are unlikely to be forthcoming, a large part of the solution lies in refocused investment strategies, better demand management, and improved public spending efficiency.
