The gains extend over a lifetime and are discounted to the present. If some of these gains accrue to others, governments need to stimulate individuals to take them into account in making decisions. Public action may also be needed if poor individuals cannot mobilize the resources to finance the investment now, despite a promise of big gains in the future. This human capital framework has been a driving force for the huge investments in education in developing countries in the past 40 years. In addition to education’s social benefits, the recognition of its long-term economic benefits has spurred finance and budget ministries to action. In global terms, education spending has mushroomed from 3.7 percent in 1970 to 4.5 percent of GDP in 2002 (see Figure 4.1). This has led, by some accounts, to profound increases in the number of young people going to school, particularly at primary levels.
