A huge spending tab looms. The financial pressures will prompt nations to think creatively about their needs.
As the global economy undergoes a series of transitions and strains in the years ahead, innovation will emerge in some unexpected places. Consider the case of infrastructure. Our analysis of historical
and projected spending allows us to look directly at looming stresses in the form of dual financial pressures: the total spending needed to support the massive scale of maintenance, renewal, and new investment, as well as the degree of change this spending represents relative to GDP (exhibit).
The United States, which has long neglected its infrastructure and faces a massive absolute and relative tab, is one place where pressures for innovation are building. Latin America and India, which have underinvested in the type of cutting-edge infrastructure required to support projected growth, will also need to think creatively. Both have to step up financing by more than two percentage points relative to GDP and to increase their total spending sharply (by factors of four and six, respectively). These challenged countries will need to dream up new ways to curb spending, boost financing, and counteract bottlenecks in planning and execution.
By contrast, while China’s total needs are huge, its aggressive spending in recent years has exceeded the level required to support growth going forward and is probably unsustainable. That’s also true in Japan. Overall, we estimate that countries could reduce required spending by as much as 40 percent by seeking out innovative approaches that build on global best practices such as selecting projects more thoughtfully, streamlining their delivery, and using existing infrastructure more productively.
