Highlights:


  • Long-run prospects for economic growth and prosperity crucially depend on human capital.
  • Human capital investment has the highest potential reward when made earlier rather than later in life.
  • Early childhood and later investments are complementary, so the long-term payoff of early childhood effort depends in part on the quality of later interventions, such as K-12 education.
  • Formal investments in human capital have failed to keep pace with the nation’s growing demand for skilled workers, suggesting constraints in our education system.
  • Maximizing the ultimate benefits of early childhood education may well require improving the quality of educational efforts later in life.

This speech was delivered by John Weinberg, special advisor to President Lacker. 

Good afternoon, and thank you for the opportunity to speak to you today on what is arguably one of the most critical economic policy topics of all: the skills of our workforce. To set the stage, let me begin by explaining why a Reserve Bank president might be interested in this topic. Part of our job at a regional Federal Reserve Bank is to understand how economic growth is unfolding in our region and in our national economy more broadly. We hear regularly from our constituents and partners throughout our District, which runs from Maryland down through South Carolina and includes almost all of West Virginia, that the long-run vitality of a community depends crucially on the skills of its people. Economists, and increasingly others, refer to such skills as human capital. It has become apparent that human capital investment is a critical determinant of an economy’s longer-run potential. As policymakers, we need to know whether investments in skills through education and work experience are making the most of the raw abilities that each new cohort of Americans brings with them. We at the Richmond Fed have found it useful to look at questions regarding early childhood education through the broader lens of human capital investment. Before I discuss these ideas in more detail, I must note that the views I express are my own and should not be attributed to anyone else in the Federal Reserve System.1

Human Capital Investments

The human capital approach treats skills as one of many kinds of investments available to individuals: It views skill acquisition as influenced by the associated payoffs or “returns.” It allows for these payoffs to be monetary or nonmonetary (such as the pleasure we experience from learning or having an intellectually challenging job, for example). Furthermore, it suggests that human capital investments ought to be “front loaded,” that is, occur primarily earlier rather than later in life. Investing early in human capital makes sense for three reasons. First, it provides a longer time horizon over which to reap the rewards and recoup the cost of the investment. Second, investing late is costlier in terms of the forgone opportunities from spending time learning rather than earning, because earnings inevitably rise with age and experience. Third, there is compelling evidence that “skills beget skills”: Early investments in human capital make later investments more productive.2

This complementarity between early and later investments in human capital suggests that we ought to think about early childhood education within the broader context of human capital investments that take place later in life. Formal education is key among these, and substantial public funding is aimed at providing the means and environs for people to acquire it. These include the universal availability of a free public K-12 education and a highly subsidized public college system thereafter. 

Let me give you a sense of substantial scale of public support for education in the United States. Taken together, the expenditures of public elementary schools, secondary schools and degree-granting postsecondary institutions amount to 5.8 percent of GDP.3 The level of spending is similar in most developed nations, though the precise mix varies. Public elementary and secondary schools account for two-thirds of these expenditures.4 This makes public school essentially free for all. Moreover, the attendees of public K-12 schools, far from being disproportionately underprivileged, constitute a very broad cross-section of American households. I will return to this point.

Human Capital Outcomes

To what extent has the widespread public provision of education given rise to cohorts ready for higher education and the workplace? A brief glance at some summary measures suggests that we could do better. Nationwide, about 20 percent of high school students fail to graduate within four years, with the number being as high as 40 percent in some large urban school districts. At public, four-year, degree-granting institutions, over 40 percent of enrollees fail to graduate within six years.5 

At the same time, our country appears to be experiencing what economists refer to as “skill-biased technical change” — the growing use of advanced technologies that increase the demand for skilled workers. Yet our investments in human capital have not kept pace with this demand. After rising rapidly for much of the 20th century, the average number of years Americans spend in school has leveled off and, since the 1970s, has remained stubbornly stable at roughly 14 years.6 The share of high school graduates who immediately enroll in four-year college has remained constant around 42 percent since 2000.7 But over the same period, college appears to have become an increasingly attractive proposition. The wages of college graduates (though not the wages of those with some years of college but no degree) have increased steadily relative to the wages of those with just a high school education.

The fact that so many do not enroll despite a widening college wage premium has profound implications. For one, it raises the possibility that those who do not currently enroll assess their odds of collegiate success as low enough to outweigh the high returns associated with completing a degree. In other words, our K-12 education system is failing to respond to the increasing demand for college-ready graduates.

Indeed, K-12 systems seem to have acknowledged this, and college readiness is becoming an area of focus at high schools nationwide.8 Interestingly, the emphasis placed by high schools on college readiness may have the unintended consequence of discouraging students who view themselves as unlikely to attend college. If students believe the only reason to succeed in high school is to attend college, they, or their families, might not see much value in doing what is required to graduate from high school. This can contribute to poor performance and high dropout rates in high school9 and to the increasingly frequent reports we hear from employers that have trouble finding adequately prepared workers for jobs that do not require a college degree.

What does all this mean for early childhood efforts? If students and their parents are aware of the limited ability of their K-12 system to prepare them for college, or to provide them with useful skills when college is not their best option, they may be less likely to make the effort needed to leverage the benefits of early childhood education. One possible result is that the value of early childhood education may be diluted or lost.

The last point drives home a theme I want to highlight: The ability of our K-12 educational system to help people realize their potential will affect what results we can expect from earlier investments. This view represents the flip side of the familiar idea that early human capital investment improves the efficacy of later educational investments. It also suggests that early childhood investments made in conjunction with well-functioning systems in K-12 and beyond may be capable of yielding even greater payoffs than what research has uncovered so far.10

Challenges Facing Early Childhood Education

Another important theme that emerges from the human capital literature is that human capital is multidimensional: Any attribute or skill that rewards the individual contributes. Cognitive skills – that is, the mental abilities that relate to learning, problem-solving and so on -- are an important part of an individual’s human capital. Cognitive skills have been shown to be associated with positive outcomes in adulthood. But noncognitive skills, such as initiative and motivation, are also critical. Indeed, Nobel Laureate James Heckman and other scholars have argued that it is through the channel of noncognitive skills that early childhood interventions lead to better outcomes in adulthood.11 Such skills make it possible for us to acquire more complex cognitive skills, and they also are critical for success in the labor market. Noncognitive skills, by their very nature, are harder to measure but, make no mistake, they are clearly relevant. For example, we routinely hear from employers and workforce development professionals around our District that a lack of “soft skills” is a major obstacle to hiring and employment.

It is also true, however, that the positive effects of early childhood interventions, especially on cognitive outcomes, may fade out over time. This appears to be true for both “model” programs, which are typically small, intensive, high-quality interventions, as well as for large-scale public programs such as Head Start.12 An early study compared outcomes for children who participated in Head Start with those of their siblings who did not.13 The use of siblings allowed the researchers to study differences in outcomes that were not attributable to family circumstances. The study found that while both white and African-American students experienced gains in test scores initially, the gains for the latter group, but not the former, diminished after they left the program. Subsequent research has confirmed these “fade-out” effects.14 This suggests that human capital, like its physical counterpart, may “depreciate” in the absence of ongoing high-quality investment.

The challenge of fade-out may be related to the link between parental circumstances and K-12 school quality in the United States. The K-12 system here is heavily dependent on local economic conditions for funding: Property taxes, on average, raise about 36 percent of all revenue needed to run public K-12 schooling.15 Not surprisingly, school districts with higher median incomes raise more revenue locally and, despite attempts by state and federal funding to offset this, tend to spend more on instruction per student. By contrast, in most other developed nations, this link is less strong and local property taxes less important. The Norwegian model of financing, for example, almost completely decouples parental circumstances from the revenue collected within a school district.16 This is an important point to bear in mind: Early childhood efforts in the United States must fight the headwind created by the prevailing model of school funding, something that they may not face elsewhere. Indeed, the correlation between school funding and parental income might help explain why the gains from early childhood education appear less persistent for some student populations.

Another challenge is being able to provide quality early childhood education on a large scale. The most successful programs tend to be those that are intensive and use highly trained personnel to target relatively small groups of students. On the other hand, research on the effectiveness of large-scale programs suggests that the gains from these programs tend to be smaller and less persistent. A recent study of Tennessee’s Voluntary Prekindergarten program has been widely cited for its negative findings: By second grade, students who participated in the program actually performed worse than those who did not.17 The lessons of this study are still being investigated but we do know that, within other large scale programs such as Head Start, more intensive interventions such as full-day service and frequent home visits are associated with better outcomes.18 This level of intensity would be costly to sustain in large-scale programs, and so it follows that there must be a trade-off between the quality of the intervention and the number of children that it reaches.

Encouraging a Lifetime of Human Capital Investment

If funding for early childhood education is going to be constrained, as seems likely to be the case over the medium term, then I believe a case can be made for targeting resources to those for whom outcomes would change the most. There is widespread agreement in the academic literature that disadvantaged students (for example, those coming from families with low incomes or parental education) experience the greatest improvement in outcomes from early childhood interventions. Research has also found that such targeted spending is likely to have a larger effect on reducing the persistence of inequality across generations than broad-based spending.19 It’s a good thing that some easily observable characteristics can tell us whose outcomes are likely to be benefited most by early childhood efforts, because it opens a path to setting eligibility requirements and judiciously targeting resources. Such targeting has in fact been a feature of some early childhood investments. For example, the Minnesota Early Learning Scholarships Program gives pre-school-aged children from low-income families access to early childhood education by paying scholarships directly to the program of their choice. From 2016 onward, the programs will be required to maintain a minimum rating to be eligible for funds.20

I also want to stress a more general principle that we need to keep in mind when thinking about the allocation of public funding, which is the importance of equalizing marginal societal benefits: The next dollar spent ought to yield society the same bang for its buck no matter how it is ultimately allocated. In essence, this principle provides a guide to balancing competing resource demands. I and many others have long argued that a more balanced portfolio of educational spending would devote more resources to early childhood education. The reason is that under current arrangements, the marginal return to investments in early childhood appear to be large relative to other educational expenditures.

Finally, at the beginning of my remarks I discussed the idea that human capital investments at various stages of life are complementary. This idea also has important implications for what an appropriately balanced portfolio of education spending looks like. The evidence suggests that investments in early childhood can increase the effectiveness of human capital investments made later in life. Conversely, investments in K-12 education will also increase the long-term payoff to early childhood investments.

In conclusion, I should note that while what we have learned so far clearly underscores the power of early childhood education, even more remains to be learned about the interplay of forces that determine its ultimate efficacy. I’ll leave you with the idea that we can only unlock the full transformative potential of early childhood education in the context of effective human capital investment in K-12 and beyond. Thank you for your attention.
