In Latin America, Hard Hats and Tools are no longer only for Men

Women that have joined road maintenance has increased significantly.

While driving around rural areas of Puno in Peru, Caaguazú in Paraguay or Granada in Nicaragua, do not be surprised to see women lifting rocks from the roads and using shovels and picks alongside men.  In fact, in the past 15 years, the number of women that have joined organizations in charge of routine road maintenance in Latin America has increased significantly and with this their life conditions have improved dramatically.

Does Your Country Export What It Should?

Customs reforms have made trade easier in Georgia. Photo - Irakli Tabagari / World Bank.One of the core principles of trade economics is that of “comparative advantage.” First described by David Ricardo, the theory says that countries are best off if they specialize in products that they can make relatively more efficiently – with lower opportunity cost – than other countries. If this happens, the theory goes, global welfare will increase. This concept is more difficult than it sounds, however – as Paul Krugman has pointed out quite eloquently – and benefits from illustration.

Basketball genius Michael Jordan stars in one example sometimes used in textbooks and classrooms: If Jordan mows his lawn faster than anyone else in the neighborhood, he has anabsolute advantage in lawn mowing. But that doesn’t mean that he should mow his neighbor John Smith’s lawn, because that would come at an opportunity cost: in the same two hours it would take Jordan to cut the grass, he could earn much more by playing basketball or making a commercial.

While it is difficult to measure comparative advantage in world trade, one indicator is something called “Revealed Comparative Advantage” (RCA). This is a measure of how a country’s exports compare to those of a bigger group, such as a region or the rest of the world. For example, if a country’s RCA in wheat is high (typically greater than one), that means wheat makes up a higher share of that country’s total exports than it does of the world’s exports. This suggests that that country is a more efficient wheat-producer than the average country.

But countries don’t always produce the products in which they have a revealed comparative advantage. Sometimes Michael Jordan mows the lawn. Let’s take a look at a couple of examples from this new data visualization tool.

The need to improve transport impact evaluations to better target the Bottom 40%

Julie Babinard's picture
In line with the World Bank’s overarching new goals to decrease extreme poverty to 3 % of the world's population by 2030 and to raise the income of the bottom 40% in every country, what can the transport sector do to provide development opportunities such as access to employment and services to the poorest?

Estimating the direct and indirect benefits of transport projects remains difficult. Only a handful of rigorous impact evaluations have been done as the methodologies are technically and financially demanding. There are also differences between the impact of rural and urban projects that need to be carefully anticipated and evaluated.

Can we simplify the methodologies?

Despite the Bank’s rich experience with transport development projects, it remains quite difficult to fully capture the direct and indirect effects of improved transport connectivity and mobility on poverty outcomes. There are many statistical problems that come with impact evaluation. Chief among them, surveys must be carefully designed to avoid some of the pitfalls that usually hinder the evaluation of transport projects (sample bias, timeline, direct vs. indirect effects, issues with control group selection, etc.).

Impact evaluation typically requires comparing groups that have similar characteristics but one is located in the area of a project (treatment group), therefore it is likely to be affected by the project implementation, while the other group is not (control group). Ideally, both groups must be randomly selected and sufficiently large to minimize sample bias. In the majority of road transport projects, the reality is that it is difficult to identify control groups to properly evaluate the direct and indirect impact of road transport improvements. Also, road projects take a long time to be implemented and it is difficult to monitor the effects for the duration of a project on both control and treatment groups. Statistical and econometric tools can be used to compensate for methodological shortcomings but they still require the use of significant resources and knowhow to be done in a systematic and successful manner.

Why we were happy when our bosses raised employee parking rates... Or how parking requirements drive modal choice

Recently, as part of a broader cost cutting initiative, World Bank management decided to do away with a long standing policy of subsidizing parking for its employees. Those of us who work on the Bank’s transport projects and help cities develop more sustainable mobility systems saw this is as a welcome development… losing some friends in the process. 
 
This personal example, along with a recently completed pilot we conducted on corporate mobility programs, inspired us to share some insights on the dramatic role parking-related regulations and incentives can play in influencing the decisions made by all stakeholders with regard to modal choice –whether it be private developers, property managers, employers or employees:

For rural communities, good roads mean the world

Coffee beans in the hands of a Peruvian farmer.

On a Friday evening last November, twelve mayors from nearby districts gathered at the municipal office building in Tarapoto, Peru. Even though the rainy season was just ramping-up in this lush tropical area of the country, local roads were already being washed away. These mayors were eagerly planning for the local Provincial Road Institute to use their tractors to protect their roads to counter the negative effects of the rain.
One of them cried out, “How will my people bring grapes and coffee to local markets without good roads? Our products are going to rot and my people are going to suffer.”

How avocados are changing the way of life of Peruvian farmers

A five hours’ drive south of Lima lays the coastal provinces of Chincha. If one heads inland into the deserted mountains that are typical of costal Peru, one would be surprised to find agriculture blanketing the valley floor. For centuries local communities in these rugged terrains have been using water from small meandering streams to grow maize, and eke out a living by selling surpluses at nearby markets. However, in recent years the growth of industrial agriculture has squeezed these communities, making it hard for them to survive in these ancestral lands, forcing many of them to move to nearby cities such as Chincha Alta.

Pensioners Paying for Projects: A new meaning for PPP in Latin America?

Public-Private Partnership (PPP) projects in infrastructure have traditionally been financed by banks. However, interest in new funding sources is increasing as long-term money from banks has become more difficult and expensive to get, while the assets held by pension funds and other institutional investors have continued to soar. In a context of low bond yields, pension funds are looking for attractive long-term investment opportunities to diversify their holdings and meet their long-term payment obligations. Realizing an opportunity to match supply and demand, governments and investors in the developed and developing world have turned their attention to Project Bonds, debt instruments issued by PPP project companies in the capital markets as a way to fund infrastructure investments.

These “Project Bonds” mostly target institutional investors - including pension funds, and have generated a great deal of interest among investment bankers, lawyers and investors. All this hype raises a number of questions: Are these “Project Bonds” really living up to expectations? Can governments really rely on Pensioners Paying for Projects (a newfound meaning for PPPs!)? What do we need to do to turn these instruments into a significant source of financing and close the infrastructure investment gap?
