Investing in Yourself:
An Economic Approach to Education Decisions
Scott A. Wolla, Senior Economic Education Specialist
“When I travel around the country, meeting with students, business people, and others interested in the economy, I am occasionally
asked for investment advice…I know the answer to the question and I will share it with you today: Education is the best investment.”
—Federal Reserve Chairman Ben S. Bernanke, September 24, 20071

One of the most important investment decisions you will ever make is the decision to invest in
yourself. You might think that investment is only about buying stocks and bonds, but let’s take a
step back and consider investment a little differently. Economists use the word investment to refer
to spending on capital, which can be either physical capital (tools and equipment) or human capital
(education and training). Let’s briefly look at each type.

Investing in Physical Capital
A firm invests in itself by buying capital that it uses to improve what it does. In other words, it
invests in physical capital to earn higher profits in the future. For example, a firm might invest in
new technology to increase the productivity of its employees. The increased productivity raises
future revenue (income earned by the firm) and profits (revenue minus costs of production). Seems
like an easy decision, right? Well, before a firm invests in physical capital, it must consider three
very important points.
First, a firm invests in technology now with the expectation that it will lead to higher revenue
and expected profits in the future. But this expectation might not be realized. For example, the
technology might not increase productivity as much as the firm expected. Or the demand for the
good the firm produces might decrease, resulting in less revenue than expected.
Second, a firm considers other investment alternatives. A firm can invest in many ways to raise
future profits. For example, maybe investment in technology A results in profits, but investment in
technology B, which is more expensive, leads to much larger profits.
Third, a firm also considers the potential return on investment (ROI). The ROI is a performance
measure of the effectiveness of an investment. It is calculated as the net gain (gain from investment
minus cost of investment) divided by the cost of investment. A firm compares the expected gain
with the investment cost to make a sound decision. Of course, the result of any investment lies in
the future and must be projected. Predicting the future is always tricky; therefore, any uncertainty
about the result must also be considered.

Investing in Human Capital
Investment in human capital is the effort that people expend to acquire education, training,
and experience. People invest in their human capital for the same reason a firm invests in physical
capital: to increase productivity and earn higher income. An added benefit is the increase in job

opportunities for those with more education: The unemployment rate for those with a bachelor’s
degree is 4.1 percentage points lower than for those with only a high school diploma (see the first
graph). Of course, higher education is expensive. To increase the likelihood that the investment
will pay off, let’s consider three points.

NOTE: In December 2011, the unemployment rate for those 25 years of age and older with at least a bachelor’s degree
(blue line) was less than half that for high school graduates of the same age with no college (red line).

First, an investment in human capital might not pay off. Just as a firm’s investment in physical
capital involves risk, there is also a risk that the expected outcome from investing in human capital
will not be realized. Research consistently shows a correlation between more education and higher
income (see the second graph), but there is no guarantee. One way to think about the ROI in human
capital is the college wage premium, which is the percent increase in earnings of those with a bachelor’s degree compared with those with only a high school diploma. Recent research suggests that
the college wage premium has been growing—from 40 percent in the late 1970s to 84 percent in
2012.2
Second, people should consider what kind of an investment to make. Getting an education will
most likely lead to higher income, but there are vast differences in the projected income and job
opportunities of the various courses of study available. For example, according to the Bureau of
Labor Statistics (BLS), an elementary schoolteacher with a four-year degree earned $51,380 (median)
in 2010,3 while a computer programmer with a four-year degree earned $71,380 (median) in 2010.4
Both earned a higher income than they would have if they had not acquired a college degree, but
the difference between the median earnings is significant.
The job opportunities available in different professions also vary. The BLS forecasts job outlooks
for various occupations. For mechanical engineers (2010-20), the BLS forecasts job growth of 9
percent,5 while for registered nurses job growth of 26 percent is expected.6 Again, there is a signifi-

cant difference. Given these facts, does that mean that you should not become an elementary
schoolteacher? Does it mean that you should consider only computer programming or nursing?
No, but the median income and the expected job growth rate are two factors to consider when
making decisions about future education and training. In fact, there are many opportunities to gain
training and valuable job skills besides the usual college route. Vocational, technical, and trade
schools teach specific, practical jobs skills that can lead to a good job within 2 to 4 years. For example, many such schools offer programs in computer-aided design and drafting (CADD); law
enforcement; heating, ventilation, and air conditioning (HVAC); and information technology (IT).
Third, people should consider the cost of various kinds of educational institutions when they
think about investment in education. For example, the average cost of attending a four-year public
university (tuition, room, and board) from 2007 to 2011 was $58,623, while the average cost at a
four-year private university for that same period was $125,604.7 Does that mean you should consider
only public universities? No, but cost should be considered in making your decision. The ROI for a
would-be elementary schoolteacher would be higher if he or she chose to attend a four-year public
university.

Conclusion
A firm invests in physical capital in an attempt to increase its revenue (income) and potential
profit, but only after considering the return on investment. People might consider using a similar
strategy when deciding whether and how to invest in their own human capital. ■
