AP Economics: 15 January 2010

Prayer (alphabetical):

Today we have the scheduled Ch. 15 Multiple Choice Test. Put your name on the Scantron and the Test. You may write on the Test. If you finish early, you may take out non-Economics material while you wait.



We will pick up where we left off: Economic Growth Chapter 17

Chapter Overview

After discussing the classical model, the chapter presents material on the sources
of long-run economic growth (with particular emphasis on productivity growth)
and the importance of infrastructure. The chapter concludes with a section on innovation waves.

Chapter Outline
Aggregate Production Function, p. 455, 6:55

The Cobb-Douglas aggregate production function is explained along with constant returns to scale and diminishing productivity returns. The author discusses the role of technology on economic growth.



Product Markets, p. 456; Labor Markets, p. 456, 2:27

Mr. Clifford's (except for the spelling errors) 60 second explanation of the differences between a perfectly competitive product market and a perfectly competitive resource market. Notice that the firms both have a horizontal curve but in the product market it is demand and in the resource market it is supply.



Capital Markets: Saving and Investment, p. 458

Personal Savings and Investment are Important for the Economy, 6:44.

Dr. Demos Vardiabasis on the post WWII global economy http://bit.ly/m549.



Implications for Economic Growth, p. 460

The unemployment rate held steady at 10 percent in December 2009. Paul Solman travels to Atlanta to gauge the hiring outlook in a down job market, 7:17.



Checkpoint: The Classical Model, p. 460
Sources of Long-Run Economic Growth, p. 460
Growth in the Labor Force, p. 461, 4:26

Changing Gender Roles at Home

The rapidly increasing number of women in the labor force has been both a cause and effect of the shift in gender roles in recent years. Women have had less time and energy to devote to their traditional role as homemaker. This has triggered a seismic shift in the division of labor in many households.

Checkpoint: Infrastructure and Economic Growth
The Changing Face of Innovation Waves

Ideas for Your Classroom Audience
The best illustration of the importance of the rate of economic growth is the rule
of 72 (or 70 in some texts). Use different growth rates and illustrate how long it
takes for a countrys GDP to double. Follow this up with Question 7 from the endof-
chapter Questions and Problems (the question asks whether a 1.4% growth
rate is so different from a 3.4% growth rate).

The text mentions Somalia as a particular country that has suffered due to its
severe political problems. Take a virtual �gfield trip�h to Somalia on this website
from BBC News. See the Web site at http://news.bbc.co.uk/1/hi/world/africa/
country_profiles/1072592.stm.

Chapter Checkpoints
The Classical Model
Question: The classical model relies on competitive markets for labor, products,
and capital to keep the economy near full employment and output. The United
States has enjoyed nearly 3 decades of high employment, high growth, and low
inflation, interrupted by two short and mild recessions. Has the recent growth in
globalization and trade liberalization introduced more competition into labor, capital,
and product markets, making our economy look and act like classical economists
envisioned?

The point is to check that students can: relate their understanding of the classical
model to changes in the global economy.

Sources of Long-Run Economic Growth
Question: In 2006, Warren Buffett, the world�fs second richest individual, announced
that over the next few years he would be giving 85% of his wealth, over $30 billion,
to the Bill and Melinda Gates Foundation. The foundation focuses on grants to
developing nations, helping the poorest of the poor. What suggestions would you
give the Foundation to help these developing nations grow?

The point is to check that students can: relate the factors that affect long-run economic
growth to the activities of a foundation like the Gates Foundation.

Infrastructure and Economic Growth
Question: Imagine a country with a “failed government” that can no longer enforce
the law. Contracts are not upheld and lawlessness is the order of the day. How could
an economy operate and grow in this environment?

The point is to check that students can: understand how important the legal framework
is to economic growth.

Extended Examples in the Chapter
The Changing Face of Innovation Waves
Looking back to Schumpeter’s creative destruction, this section argues that the time
between waves of innovation is becoming shorter. It cites the work of William
Baumol, who contends that capitalism’s ability to produce a steady stream of new
ideas and processes has made capitalism the most efficient growth machine and the
best economic system for generating growth.
The sources cited for this section are “Catch the Wave: The Long Cycles of
Industrial Innovation are Becoming Shorter,” from The Economist, February 19,
1999, and The Free-Market Innovation Machine: Analyzing the Growth Miracle of
Capitalism, by William J. Baumol (Princeton: Princeton University Press, 2002).

Examples Used in the End-of-Chapter Questions
Questions 4 and 7 reference growth rates in different countries. Question 11 references
per capita income (or output). To learn more about growth rates and per
capita income in different countries, visit the CIA Factbook Web site at
https://www.cia.gov/library/publications/the-world-factbook/.
For Further Analysis
Immigration: Good or Bad for Productivity?
The example provided in the student handout can be used as a small group exercise
or as an individual exercise. It is also suitable to use as the basis for a classroom
debate. The exercise expands on the chapter’s coverage of the sources of long-run
economic growth by exploring the issue of immigration. Students are directed to
read two articles about different “types” of workers and use them as a basis for analyzing
the impact of immigration.

See the paper on guest-worker programs by Mark Krikorian, executive
director of the Center for Immigration Studies for a presentation of this viewpoint.

Web-Based Exercise
This example requires students to compare two different measures of economic
freedom and to assess what aspects of economic freedom they feel are most important.
This assignment builds on the discussion on the text and also provides an
opportunity to discuss the effects of corruption on economic growth.
The Dimensions of Economic Freedom
Visit the Web site of the Fraser Institute to read its Economic Freedom of the World
report. Compare it with the Index of Economic Freedom (from the Heritage
Foundation and The Wall Street Journal) by answering the following:
1) Which are the top ten countries according to each source? (Web sites are
http://www.freetheworld.com/2006/EFWinternational-rls.pdf and http://www.
heritage.org/index/topten.cfm.)
2) What categories are included in each definition of freedom? (You may consult
the list of categories in the text for the Fraser Institute; for the Heritage
Foundation, see the Web site at http://www.heritage.org/research/features/
index/chapters/htm/index2007_chap3.cfm).

Tips
The challenge with regard to this material is how much students may take for
granted about their freedoms and the economy in which they live. Trying to give
them another perspective will help them understand the strengths of the U.S. economy
and the challenges of other countries.

HANDOUT 17-1

Immigration: Good or Bad for Productivity?
Growth in the labor force is listed as a major source of long-run economic growth. But what
causes the labor force to grow? As noted in the text, immigration is causing the U.S. population to
rise faster than anyone thought. Is this good for productivity?
Read the article titled “Keeping Out the Wrong People: Tightened Visa Rules Are Slowing the Vital
Flow of Professionals into the U.S.” by Spencer E. Ante in Business Week (October, 2004, pp. 90–
94, available on the Web at: http://www.competeamerica.org/news/media_coverage/2004_10/
20041004_bw.html.
Then read “The Worker Next Door,” by Barry R. Chiswick in The New York Times, June 3, 2006,
p. A23. This article is available on the Web at: http://www.nytimes.com/2006/06/03/opinion/
03chiswick.html?ex=1306987200&en=676f30a3dbaf85e9&ei=5088&partner=rssnyt&emc=rss.
Based on the two articles, assess whether immigration is good or bad for U.S. productivity.

Resources
"Mankiw's 10 principles of economics, translated for the uninitiated", by Yoram Bauman, http://www.standupeconomist.com . Presented at the AAAS humor session, February 16, 2007. For the record, the talk contains two unattributed quotes ("9 out of 5" is adapted from a line attributed to Paul Samuelson---although apparently he said it about Wall Street indices, not macroeconomists---and "wrong about things" is paraphrased from P.J. O'Rourke's Eat the Rich) and, of course, the Einstein "simple" quote is an intentional misquote. The talk is based on a published article in Annals of Improbable Research (see http://www.improb.com/airchives/paper... ), which sponsored my talk and to which you should subscribe (http://improb.com/subscribe/ ). In the paper you can see the "constructive example" of how trade can make everyone worse off (or you can just wait 50 years to see what happens with climate change).
