O mito da educacao e o crescimento economico


[...]
Education’s importance is incontrovertible – teaching is my day job, so I certainly hope it is of some value. But whether it constitutes a strategy for economic growth is another matter. What most people mean by better education is more schooling; and, by higher-quality education, they mean the effective acquisition of skills (as revealed, say, by the test scores in the OECD’s standardized PISA exam). But does that really drive economic growth? 

In fact, the push for better education is an experiment that has already been carried out globally. And, as my Harvard colleague Lant Pritchett has pointed out, the long-term payoff has been surprisingly disappointing.
In the 50 years from 1960 to 2010, the global labor force’s average time in school essentially tripled, from 2.8 years to 8.3 years. This means that the average worker in a median country went from less than half a primary education to more than half a high school education. 

How much richer should these countries have expected to become? In 1965, France had a labor force that averaged less than five years of schooling and a per capita income of $14,000 (at 2005 prices). In 2010, countries with a similar level of education had a per capita income of less than $1,000. 

In 1960, countries with an education level of 8.3 years of schooling were 5.5 times richer than those with 2.8 year of schooling. By contrast, countries that had increased their education from 2.8 years of schooling in 1960 to 8.3 years of schooling in 2010 were only 167% richer. Moreover, much of this increase cannot possibly be attributed to education, as workers in 2010 had the advantage of technologies that were 50 years more advanced than those in 1960. Clearly, something other than education is needed to generate prosperity.

[...]

And there is more bad news for the “education, education, education” crowd: Most of the skills that a labor force possesses were acquired on the job. What a society knows how to do is known mainly in its firms, not in its schools. At most modern firms, fewer than 15% of the positions are open for entry-level workers, meaning that employers demand something that the education system cannot – and is not expected – to provide. 

When presented with these facts, education enthusiasts often argue that education is a necessary but not a sufficient condition for growth. But in that case, investment in education is unlikely to deliver much if the other conditions are missing. After all, though the typical country with ten years of schooling had a per capita income of $30,000 in 2010, per capita income in Albania, Armenia, and Sri Lanka, which have achieved that level of schooling, was less than $5,000. Whatever is preventing these countries from becoming richer, it is not lack of education.
A country’s income is the sum of the output produced by each worker. To increase income, we need to increase worker productivity. Evidently, “something in the water,” other than education, makes people much more productive in some places than in others. A successful growth strategy needs to figure out what this is.
Make no mistake: education presumably does raise productivity. But to say that education is your growth strategy means that you are giving up on everyone who has already gone through the school system – most people over 18, and almost all over 25. It is a strategy that ignores the potential that is in 100% of today’s labor force, 98% of next year’s, and a huge number of people who will be around for the next half-century. An education-only strategy is bound to make all of them regret having been born too soon.
