Growth and the PPF: Easier Said Than Done

3. Long-Run Growth Economic Growth (the layman)
An increase in the total output of an economy.
Modern Economic Growth (the historian)
The period of rapid and sustained increase in output that began in the Western world with the Industrial Revolution.
Economic Growth (the humanist)
An increase in people’s standard of living
Economic Growth (the economist)
An increase in real GDP per capita!
An increase in the growth rate of output per worker?  An increase in the growth of real wages?

4. The Growth Process & The Industrial Revolution: From Agriculture to Industry
Beginning in England around 1750, technical change and capital accumulation increased productivity significantly in two important industries: agriculture and textiles.
New inventions and new machinery meant that more could be produced with fewer resources.
Growth meant new products, more output, and wider choice.
A rural agrarian society was quickly transformed into an urban industrial society.
This type of economic growth continues today in the developed world, and while the underlying process is still the same, the face is different.
Growth comes from a bigger & better workforce and more productive workers.
Higher productivity comes from tools (physical capital); a better-educated and more highly skilled workforce (human capital); and increasingly from innovation, technical change, and newly developed products and services.

5. Robert J. Gordon on Growth
George Staller Lecture, May 4, 2017
George Staller, professor emeritus of economics, died in 2009 at his home in Ithaca. He was 82. He taught at Cornell University for 49 years and as a visiting professor at Charles University in Prague, Czechoslovakia, for 15 years. He earned M.A. and Ph.D. degrees from Cornell. His research included studies that compared planned and free market economies, and analyses of industrial growth and industrial output within Soviet Eastern Europe.
Robert Gordon, a distinguished professor of economics and social science at Northwestern University and author of The Rise and Fall of American Growth: the U.S. Standard of Living since the Civil War.

6. Headwinds for US: 1) Education system, 2) Inequality increasing, 3)Socioeconomic and welfare state issues like job loss, decline of marriage, single-family homes, life expectancy, mortality, obesity

NOTES:
The “catch up” theory states that the growth rates of less developed countries will exceed the growth rates of developed countries, allowing the less developed countries to catch up.
The idea that gaps in national incomes tend to close over time is called “convergence theory”.
An economic historian coined the term the “advantages of backwardness” over 50 years ago to describe the phenomenon of less developed countries leaping ahead by borrowing technology from more developed countries.

9. Long-Run Growth Basic Sources of Growth Human Capital
More labor and the knowledge and skills acquired by labor through education and experience.
Real Economic “K”apital
More K and Better K
Capital Deepening: Increases in the stock of capital per worker.
Technological Progress
More efficient ways of organizing economic affairs that allow an economy to increase output without increasing inputs.

10. Long-Run Growth Policies
Policies to Improve the Quality of Education
Policies to Increase the Saving Rate
Policies to Decrease Taxes
Policies to Stimulate Investment and Risk Taking
Policies to Increase Research and Development
Policies to Reduce Regulations
“Industrial Policy” - Government involvement in the allocation of capital across manufacturing sectors.

15. Sources of Economic Growth: Increase in the Quality of Labor Supply
The level of educational attainment in the United States has risen significantly since 1940.
As the quality of labor increases through more education, labor productivity increases.
Policy makers in many developed economies are concerned about their ability to continue to generate growth through human capital improvements.
An interesting read...Is college worth it?

18. Sources of Economic Growth: U.S. Labor Productivity
Output per hour of work, labor productivity is a simple measure of how much a typical worker can produce given the amount of capital in the economy and the state of technological progress.
From 1947 to the worldwide oil crisis in 1973, labor productivity grew rapidly. Productivity growth fell in the remainder of the 1970s and slowly increased over the next two decades.
Since 2007, productivity growth has also slowed from recent trends, partly due to the recession.
Economists have used growth accounting to help explain these trends in productivity growth in the United States. Economic research suggests that the oil shocks in the 1970s reduced technological progress but the information revolution in the 1980s and 1990s led to a resurgence of technological progress.

1947–2011

19. Sources of Economic Growth: Technological Change & Progress
Embodied Technical Change
Technical change that results in an improvement in the quality of capital. (e.g., store cash registers then and now)
Disembodied Technical Change
Technical change that results in a change in the production process. (e.g., better organization of factory “floor”; market reforms)
Another Distinction
Invention: An advance in knowledge.
Innovation: The use of new knowledge to produce a new product or to produce an existing product more efficiently.
i>clicker question: Which one of the following would be classified as an invention?
In 1899 the Bayer Company marketed acetylsalicylic acid as a pain reliever in powder form under the name Aspirin.
In 1907 James Spangler combined an old fan motor, a soap box, a broom stick, and a pillow case into a device which was later acquired by William H. Hoover, president of the Hoover Company.
Beginning in the late 1950s, the field of nanoscience (or nanotechnology) emerged as scientists developed new techniques for the manipulation of materials billionths of a meter wide.
In 2001 Eddie Bauer and other retailers introduce stain and wrinkle resistant slacks using fabric developed by Greensboro, North Carolina based Nano-Tex, LLC. Attached to the fabric’s cotton fibers are molecular structures that create an invisible barrier that causes moisture and stains to bead on top of the fabric and prevent absorption.

20. What Causes Technological Progress? Many Say R&D
Research and Development as a Percent of GDP, 1999
The United States spends more total money than any other country on research and development.
However, when the spending is measured as a percentage of each nation’s GDP, Japan spends more.
A big part of U.S. spending on research and development is in defense-related areas.

21. Can We Use Economic Analysis to Understand the Drivers of Growth in Different Countries?
India and China are the two most populous countries and have also grown very rapidly in recent years.
From 1978 to 2004, GDP in China grew at the rate of 9.3 percent per year.
From 1978 to 2004, GDP in India grew at a lower rate of 5.4 percent per year.
WHY?? Economists Barry Bosworth from the Brookings Institution and Susan Collins from the University of Michigan used growth accounting to answer this question.
China’s rapid growth was caused by more rapid accumulation of physical capital and more rapid technological progress.
China invested much more in physical capital and was able to increase its technological progress at a more rapid rate.

22. Growth and the Environment and Issues of Sustainability
Many huge looming questions.
Is there climate change?
What’s causing it?
plants or plants?
Who should do what about pollution?
need to consider both consumption and production.
What kinds of institutions and societal structures can be utilized?
Kyoto types of agreements?
In 1997, the conference in Kyoto, Japan was widely considered a breakthrough, producing an international treaty to limit emissions of greenhouse gases.
What has happened beyond Kyoto?
Paris…?
Are we running out of resources?
Oil?
Fresh Water?
Farmable Land?

23. The End - Amen Study hard. Use the class web pages – stay informed.
Work loads of problems.
Eat well.
Take a walk once in a while.
Get some sleep.
Don’t survive on
And last but not least....
Thanks to YOU ALL for a great semester!!
And thanks to the TAs for all their hard work.
Best of luck on all your finals. I’m looking for good things from you all in our final!!
