Millions of Chinese have just celebrated the beginning of the year of the Dragon - a year which according to Chinese tradition is auspicious for ambitious undertakings. These may be required as the global economy faces severe headwinds. According to the January edition of Global Economic Prospects  (GEP)  report the world economy is expected to grow at 2.5 percent and 3.1 percent in 2012 and 2013, significantly below the 3.6 percent projected for both years in last July’s GEP. But even achieving these much weaker outturns is highly uncertain. The downturn in Europe and weaker growth in several large developing countries, such as Brazil and India, could potentially reinforce one another, resulting in an even weaker outcome. But without growth it will be more difficult to reduce the high debt of some advanced economies to sustainable levels and create much needed jobs world-wide.
In these uncertain times, a global infrastructure initiative could help the global economy regain momentum as I argue in my recent Working Paper . Such an initiative would benefit both developed and developing countries. Governments of advanced economies could support growth in their own countries through infrastructure investments by taking additional steps to attract private sector investments in bottle-neck releasing infrastructure investments that are ultimately self-financing. These investments – if well chosen - while improving future competiveness would create much needed jobs directly in the construction and manufacturing sector that have suffered from particularly high unemployment rates in several countries, and indirectly in service sector as well.
But opportunities for bottleneck-releasing infrastructure investments in advanced economies tend to be limited, since their infrastructure is on average well developed. In developing countries, to the contrary, lack of infrastructure impinges on the daily lives of millions of people, who have no access to electricity, safe drinking water, basic sanitation or all-weather roads. It also renders firms less competitive, affecting productivity, transaction costs, and output quality adversely. Many businesses are never started, since the required infrastructure services are not available. Going forward the demand for infrastructure is likely to increase even further, as population grows, urbanization rates become higher and countries grow richer.
But infrastructure is not only a by-product of growth. It can also be an important driver of economic development. As I argue in my on New Structural Economics,  economic development in any country is a process of continuous technological innovation, industrial upgrading and diversification, and structural transformation. Countries start with more than 85 percent of the population making a living through agriculture when income levels are low. At this agrarian stage, farmers produce mostly for their own consumption and the need for infrastructure services is limited. When the production moves to manufacturing, economies of scale become larger, and producers will mostly produce for other people and no longer for themselves. As market range expands, good infrastructure will enable entrepreneurs to get their goods and services to market in a secure and timely manner and facilitate the movement of workers to the most suitable jobs. Empirical cross-country studies  tend to confirm that infrastructure investment has a large effect on growth in developing countries.
Infrastructure investments in developing countries would not only raise their growth, they would also increase demand for capital goods from capital good-exporting countries, most of which are advanced economies, thereby, raising their exports and creating jobs. A US$1 increase in investment in developing countries is associated with a US$0.50 increase in imports. In 2009, about 70 percent of traded capital goods from low-income countries were sourced from high-income countries. A US$1 increase in investment in developing countries is therefore likely to be associated with a US$0.35 increase in exports from high-income countries. These are not small amounts. A global infrastructure initiative could thus generate a virtuous, self-reinforcing cycle of global growth by boosting growth in developing countries and developed countries alike.
History shows that a bold infrastructure initiative can be truly transformative. In 1919, when the young lieutenant colonel, Dwight D. Eisenhower, drove from Washington, D.C., to Oakland, California, with the Motor Transport Corps Convoy, it took him 56 days to cover the 3,250 miles, covering an average of 58 miles during daily 10-hour rides. Upon his return, he reported  that bridges were destroyed by the convoy, trucks became stuck during rain, and some roads simply could not accommodate quick and easy travel.  When Eisenhower promoted the Federal-Aid Highway Act of 1956 he envisioned that “its impact on the American economy—the jobs that it would produce in manufacturing and construction, the rural areas it would open up—was beyond calculation”. Opportunities to transform economies through infrastructure investments still abound in developing countries today—to the benefit of advanced economies.
A bold global infrastructure initiative would be especially helpful for solving the dilemma besetting the Eurozone countries. Without structural reforms to enhance the competitiveness of the debt crisis-hit countries, any stabilization measure is just buying time and problems will recur sooner or later. Moreover, fiscal adjustments are often contractionary and may further reduce demand, jobs, growth, and government revenues at least temporarily, with dire social and policy consequences. Many structural reforms on the other hand, while key to boosting growth in the medium term, might only gain traction once demand increases. A concerted push for a global infrastructure initiative could increase demand, build confidence and contribute to a sustained global recovery from the current crises. It is a global win-win.
