Technology: connecting the macro with the micro.
Macy, Anne
ABSTRACT
This paper presents unique lecture material for a workshop on the
role of technology in the economy. Technology is the vehicle to show the
connection between macroeconomic and microeconomic concepts, a
relationship neglected in many classrooms. The topic area is space and
research and development (R&D). Technology's role in growth and
development develops into the issue of public funding for R&D and
NASA's technology transfer program. Tempur foam is examined as a
successful innovation that evolved into a public company, the
microeconomic application of a macroeconomic idea. History, government
and mathematics are included to increase the applications of the
lecture.
INTRODUCTION
In the current environment of testing combined with a lack of time
in the classroom, economics becomes a more difficult subject to teach.
Modern education requires that students understand the relationships
between ideas and how those concepts interact. Unfortunately,
integrating material is easier said than done. As one begins to draw the
comparisons, the story becomes longer and the possibility that the
students become lost increases. The length of the example and the
knowledge gained by the students are sometimes inversely related. Thus,
clear examples of economic ideas combined with other disciplines are
needed to increase the opportunity to teach economics and the
probability of student understanding. This paper presents a unique way
to consider the roles and interaction between basic macroeconomics and
microeconomic concepts.
Through work for the West Texas Center for Economic Education, it
became clear that one area the teachers found difficulty with is the
production possibilities frontier (PPF). While they were able to define
and apply it to simple issues, the teachers did not know how to connect
it to microeconomics. To them, it is purely macro. While the production
possibilities frontier is a macroeconomic idea, its movements affect the
microeconomic world and visa versa. The PPF is dynamic not static. Thus,
the issue becomes how the PPF affects the firm and how the firm affects
the PPF.
By not showing the students how the entire economy interacts, the
students are left without the ability to see how the macroeconomic ideas
and policies of the country affect themselves as individuals and their
firms. One reason young individuals vote at reduced levels to other age
groups may be because they don't see how the various government
actions affect them. Showing how macroeconomic ideas and microeconomic
ideas are interrelated may encourage students to see themselves in the
economy.
The Executive Summary of the National Summit on Economic and
Financial Literacy focuses on the areas lacking in economic education
(NCEE, 2002). In particular, economic education is important for
informed citizens. It also identifies the need to integrated examples
with other disciplines. The findings of the Survey of the States Report
Card (NCEE, 2003) coincide with Executive Summary. Most states short
change economic education even it they acknowledge its importance. Both
reports note that the comprehensive understanding of an idea involves
knowing how it affects and is affected by other concepts. This lecture
addresses this concern.
As a focal point for the workshop, space was chosen. With the
renewed interest in space, space technology is timely and interesting to
students. In addition, space technology allows the teacher to integrate
economics with science, history, government, and mathematics.
Economics is one discipline that connects the other disciplines to
each other. Showing how the technology from space affects our everyday
lives increases the importance and relevance of science. Science
benefits because economics tells us why it is important and how society
uses it. A historical comparison is included to show how society has
always explored and innovated. Government expenditures and the role of
government funding for research adds a political element to the
discussion. Mathematical extensions on the stock price of the private
company are included to show how math is used in microeconomics. Thus,
the lecture can be included in a variety of courses not just economics.
This paper presents the classroom material, which is divided into
seven subtopics. The topics start with a broad macroeconomic idea and
evolve into a discussion of a firm. Economic growth and development is
the first topic, which leads into the role of technology. Reasons for
public funding of space research and development (R&D) extend from
technology and include a discussion of efficiency. A comparison with
historical exploration provides the connection from public funding to
the technology transfer of R&D. Finally, Tempur-Pedic International,
Inc. is discussed as the microeconomic application of technology and
economic growth and development.
CONNECTING ECONOMICS TO TECHNOLOGY: PEDAGOGY
Space is an engrossing topic for students. It provides the needed
hook to engage not just the students but also the teachers. When the
general public thinks of the National Aeronautics and Space
Administration (NASA), the space shuttle and the international space
station are immediately brought up. However, the public and the students
forget about the amount of technological innovation it is taking to
produce the international space station. The next step is to show how
the technology innovation affects the students' homes.
While there are a multitude of space technologies invented, tempur
foam is readily understood by every student. Some of the technologies
from NASA are so complicated, that students are unable to fully grasp
the idea. Again, losing students before the lesson really begins. Tempur
foam's best-known use is mattresses, a good which students easily
understand.
ECONOMIC GROWTH & DEVELOPMENT: EMPHASIS ON TECHNOLOGY
The basic outline of the lesson is to start with economic growth
and development and how the economy grows. In its basic form, the Solow
growth model shows that there are three ways for an economy to grow. The
economy can increase the quantity of labor or increase the quantity of
capital. The economy can also grow via technological advances. The
technological advances allow the existing labor and capital to be more
productive. It increases the quality of our work. We are able to do more
with fewer inputs. This is called capital and labor augmenting technical
change.
The production possibilities frontier and its outward shift are
introduced as a visual to show an economy growing. Technology advances
allow society to be more productive. Greater productivity allows for
greater consumption and a higher standard of living. The economy expands
permanently. It is interesting to point out to the teachers and students
that the expansion is permanent. Once we learn to do something, we
don't forget. In addition, it is important to point out that the
technology can be things like advances in health care not just a faster
computer chip.
The expanding PPF leads to an increase in the standard of living
for a country. For a country or company to remain as the leader, it must
continue to innovate or else it will be surpassed by another
country/company. Once knowledge or skills are made public, the
information can be duplicated and improved. Countries and companies do
not always respect patents and copyrights. Thus, a country/company must
continue to improve or else fall behind. The continual growth results in
a steadily increasing standard of living. The teacher can discuss with
the students that countries with high investment in R&D have higher
gross domestic product per capita than other countries. Notice that the
responsibility for innovation rests with the country or company. Here is
the first addition of microeconomics into the discussion. Not only does
a country need to innovate to move ahead so does a company.
The final idea of this section is that technological innovation
begets more technological innovation. This allows the PPF to shift out
faster, steadily increasing the standard of living. Some students need a
visual and an inverted triangle does the trick. Basic research is the
research done in the bottom part that is very narrow. As innovations
occur, they lead to more innovations and the economy moves up the
triangle as the entire amount of R&D increases.
A common statement by a student is that a certain technology
(usually for the military) hasn't benefited him/her personally.
This allows the instructor to address the idea of public goods and
public benefits versus private goods and private benefits. An innovation
may improve society and as a member of society, it positively affects
the student even if the individual can't document the improvement
on personal standard of living.
REASONS FOR PUBLIC FUNDING OF R&D
After the instructor has established the role of technology in the
PPF, the next step is to address whether the R&D into technology
should be public or private. Basically, why don't we let firms do
the R&D instead of the government?
The risk-return or cost-benefit relationship from the R&D is
not favorable in the time frame firms require. As risk/costs increases
so does the required return/benefit. But the return to some R&D
initiatives cannot be projected with a great amount of certainty because
space exploration has too many unknowns.
Market failure exists when there is a divergence between social and
private costs and benefits of a particular activity. Research that
generates growth has social benefits that exceed private benefits.
Government can encourage research where the market would fail.
Notice how an instructor with an intuitive class can discuss the
social benefits and the social costs of an innovation. A new technology
may decrease the need for certain types of jobs. This frees up the labor
for new uses. However, the news covers the loss in jobs and not the new
jobs created by the increase in technology.
The next logical step is to discuss the characteristics for public
funding of R&D. The lesson focuses on six main issues: cost, size,
success, time frame, uses, and danger.
The first two issues are cost and size. Basic research is
expensive. Firms conduct R&D on projects with a high probability of
profit. Space exploration and R&D are too expensive for any one firm
to undertake. In addition, the magnitude of this research is best
handled by an entity of comparable size.
A related example is that of pharmaceutical firms that work on
medications for diabetes, heart disease, arthritis, etc. Very little
work is done on rare diseases, which usually are more deadly or
debilitating but have very little profitability. New drugs for common
ailments typically cost more than $300 million to innovate. A firm
won't spend that amount of money unless it believes it can recoup the amount in profits.
R&D is an uncertain process. There are many more failures than
there are successes. A private firm has profitability measures to meet.
Failures could limit or eliminate the firm's ability to secure
funding and maintain cash flows.
R&D takes a long time. NASA has 10-year and 25-year objectives.
Financial markets want quarterly results. How would the average investor
react if a firm announced it wouldn't be profitable for at least 10
years and then maybe not profitable at all even if its R&D were
successful? The time frame of basic research does not match the time
frame of Wall Street.
Profitable uses of basic research are not known at the time of
innovation. Basic research can be applied to many different
fields/industries. It may take years before the secondary products are
developed. One example of this is electricity. Ask the students to think
about how many current products use electricity. The products were
developed after electricity. Electricity came first.
Space exploration is risky. It is one thing to design it on a
computer and quite another to build a space station. The liability is
cost-ineffective. How many lawyers would be ready to sue following a
space death?
EFFICIENCY
Economies look for efficient solutions to problems. Public support
of R&D allows the economy to deal with the free rider problem. Major
technology advances benefit everyone. But if one person or firm had to
pay the initial costs, it might not be undertaken. Even if a firm or an
individual did do the research, others might use the benefits without
ever having paid for the research. A free rider is an individual who
receives a benefit without paying for it.
An example is national defense. We let the federal government
organize and run the national defense because it is too costly and too
difficult to do it individually. If an individual did form his own
defense system, it is likely his neighbors would take free advantage of
the system.
Public payment of R&D also involves externalities. Innovation
has positive externalities. The marginal private benefit is less than
the marginal private cost. It is not cost effective for a firm or
individual to undertake the activity. However, the marginal social
benefit is greater than the marginal private cost. Thus, by spreading
the cost out over everyone, the individual cost is reduced and no one
entity is burdened. In return, all of society earns the positive
externalities.
The government supports certain activities that benefit all of
society but are too expensive for many individuals to pay for on his/her
own. First-time home ownership programs, education, roads, medical
research and Social Security are examples.
Allocative efficiency results when the marginal social benefit
equals the marginal social cost. If firms did do this research, the
results would belong to the firm. The firm has an incentive to keep the
technology a secret, thereby limiting its use. National funding of
R&D allows for knowledge spillover to the entire economy. Various
industries and firms can take the same technology and apply it to a
specific product or technique. This increases national output and wealth
at a greater pace than without knowledge spillover.
In essence, let the nation fund the basic research to build the
mousetrap. Then let the firms improve and specialize the mousetrap for
you and me.
So just how much does the United States spend on NASA? Table 1
shows the percentage of total federal government expenditures on NASA.
Other major expenditures are included for comparison. From the chart,
expenditures on NASA tend to range around 1%, substantially less than
the amount on other areas.
COMPARISON WITH HISTORICAL EXPLORATION
Most economics classes are viewed as part of the social studies
curriculum and taught by instructors with history backgrounds. It is
beneficial to include a comparison with historical exploration.
Historical exploration revolved around finding resources and
information.
Exploration was a means to find resources. Referring back to the
PPF, an increase in natural resources shifts out the frontier. The
Spanish and Portuguese explorers wanted to find riches. There was a
profit motive.
Historical exploration was also about finding information. What is
out there? Lewis & Clark mapped the land of the Louisiana Purchase.
Exploration has always used technology. The Wright Brothers wanted
a business but they also just wanted to fly and to be first.
Current exploration does not have the explicit profit function that
earlier explorations had. There is a profit function but it has a much
longer time frame than we are used to today. Lewis & Clark explored
during 1804-06. The settlers came in the 1860s - 1880s, 60 to 70 years
after the exploration. Very few firms have this type of time frame.
Current exploration is much more about finding information and
using and developing technology. The technologies and information are
meant for the public. But the time frame involved means the gains are
for the future public. The time frame implies an altruistic nature to
basic research and exploration. The gains are for other generations.
TECHNOLOGY TRANSFER
After establishing the role of technology for economic growth and
development, the reasoning for public funding of innovations is
presented. The next step is the tie-in with microeconomics. Capitalism
relies on firms to meet consumer demands. Public funding for R&D
allows for allocative efficiency for the initial innovations. Once the
basis has been developed, firms take over. This is called technology
transfer.
In 1962 NASA started its technology transfer program by which
technologies could be transferred to companies enabling the firms to
develop commercial products.
Some of the everyday products or services that use NASA technology
and have been a part of the technology transfer program are listed in
Table 2. It is not an exhaustive list but meant to give the students a
flavor of some areas NASA as influenced.
A logical question is to ask what types of technology NASA deems
successful. The Space Technology Hall of Fame has five criteria in its
selection process.
The first criterion is economic benefit. Higher ratings are given
to technology that has been the basis of or a significant part of a
successful product or company. Additional points are awarded for those
technologies that were developed from a partnership with the private
sector. In other words, NASA does not want its R&D to be done in
isolation. It wants private firms to be actively involved from the
beginning.
A third criterion is the amount of public awareness a technology
has generated and if it highlights the benefits of space R&D.
Technology is also judged on its impact on society and how long of an
impact or commercial application the technology has.
TEMPUR-PEDIC
While the microeconomic aspect of the workshop has been hinted at,
it now moves to the forefront of the discussion. Tempur-Pedic is a 1998
inductee into the Hall of Fame for Space Technology. Tempur is a foam
that is temperature sensitive and adjusts to weight and temperature
changes. In the 1970s, scientists at the Ames Research Center originally
developed tempur foam to relieve the intense pressure of G-forces
experienced by astronauts during rocket launches. Innovating firms were
Ames Research Center (NASA), Becton Dickinson Dynamic Systems, and
Southwest Research Institute. Notice how the initial research includes
Becton Dickinson, a private company.
In the early 1980s, NASA released the technology to the public
through the tech transfer program. One of the original innovators saw
the potential of tempur foam and developed it under the name Tempur
Foam. By 1989, Tempur-Pedic, Inc. was formed. Eventually, it became
Tempur World.
There are have been numerous spin-offs for products such as
mattresses, footwear, wheelchairs, hospital beds, etc. Tempur foam has
been added to helmets to better protect the head. Individuals bound to
wheelchairs or beds use the tempur foam to relieve the stress of sitting
or lying down all day.
Numerous other firms have licensed the technology to develop their
own good. Fagerdala World Foams of Sweden was one of the original firms
to find applications of the technology for mattresses and cushions.
Modellista Footware used tempur foam for shoe cushioning. In addition,
the shoes are resistant to blood, urine and other elements and is used
in the health care field.
Venture capital was used to fund the young company. Venture capital
is equity funding from private investors. It is difficult to obtain and
because of the risk, venture capitalists want a high return. Venture
capitalists don't enter the life cycle of a business until it has a
proven product. Thus, venture capitalists wouldn't fund the initial
R&D to innovate tempur foam but they would fund the development of
tempur foam into its various uses.
After Tempur-Pedic demonstrated sales and profitability, the
entrepreneurs decided to sell the entire firm to the venture
capitalists, which took the company public. In November 2002, two
venture capitalist groups, TA Associates and Friedman, Fleischer &
Lowe, formed Tempur-Pedic International to purchase Tempur World for
$268.00 million plus $88.8 million in refinancing. Going public means to
sell stock in the company to outsiders and to have the stock traded on
an exchange. It is also called an initial public offering (IPO). The
firm is able to gain capital but with a loss of autonomy over the firm
because now it is responsible to the shareholders. The IPO allows the
venture capitalists to get their money back through the sale of stock.
The investment banks that took Tempur-Pedic public were Lehman
Brothers and Goldman, Sachs & Co. Investment banks are financial
institutions that assist firms in issuing stock, setting the initial
price, complying with the rules and regulations of the Securities &
Exchange Commission, and selling the stock. The commissions investment
banks receive are called flotation costs.
It went public on December 18, 2003 on the New York Stock Exchange under the ticker symbol TPX. The initial price for the IPO was $14.00,
of which $0.91 of each share went to the investment banks. The stock
rose to $15.50 on its first day.
For those classes with a little more time and interest, the prices
can be examined in greater detail. From the Yahoo! Finance website, one
is able to download the historical closing prices into an Excel
spreadsheet. Using the time period set by the instructor, a stock price
chart can be generated. Table 3 shows the prices of the first two months
of TPX. The students can also access a stock price chart at various
Internet sites including bigcharts.com and stockcharts.com.
Students can also find the average price, the minimum and maximum
of the stock price as in Table 4. The instructor is able to discuss the
volatility of the stock price and how stock prices fluctuate with demand
and supply for the stock. For example, the stock price rose on the first
day from $14.00 to $15.50, indicating demand was greater than supply.
The closing stock price has ranged from $14.74 to $17.90 over the first
two months.
An alert student will note that the supply of stock in a firm is
perfectly inelastic. There are a limited number of shares outstanding or
available for purchase. Every share of stock is not traded every day.
Instead buyers and sellers meet in the marketplace of the New York Stock
Exchange each day to conduct trades. The number of buyers versus the
number of sellers determines the price at that time. The example is
reinforcing the ideas of demand and supply presented earlier in the
class.
To finish the circle all one has to note is that Tempur Pedic pays
taxes, which can be used by the government to fund further R&D to
innovate new technologies for economic growth and development, which can
be used by other firms to make goods for customers creating a higher
standard of living for all.
CONCLUSIONS
Connecting macroeconomics and microeconomics demonstrates to
students the dynamic nature of the economy. Instead of viewing growth
and development as an isolated idea from the profitability of a firm,
the integration of the ideas allows students a deeper understanding of
the working of the economy. By completing the circle within the extended
example of tempur foam, the progressive nature of innovation is more
easily seen. As a result, students have a better understanding of how
the economic cycle works. This workshop was been conducted several times
with great success. In particular, the teachers appreciated the
integration of macroeconomic and microeconomic ideas, noting that
nothing else like it was in the standard textbooks. In addition, the
inclusion of history, government and mathematics increased the
likelihood of the lecture material being used in the classroom. Because
so many states have knowledge or skills requirements, Table 5 presents
the key vocabulary terms so the teachers can match the lessons with
their evaluation rubrics.
If a goal of economic education is to increase the analytical
skills of students, examples that show the integration of ideas must be
presented to assist the students in their development of critical
thinking skills. Technology can be a very general term to students.
However, its role in economic growth and development of a country and of
a firm is very specific.
