 I. Overview      A. A purely competitive market exists when the number of          independently acting buyers and sellers is so large          that individual participants have no affect on market          price and quantity.     B. Products sold are virtually identical. Agricultural products          such as potatoes and wheat are examples of           competitively sold products.     C. Pure competition industries as defined is difficult to find          because some monopoly power usually exists.     D. Price is determined by intersection of industry supply          and demand.     E. Individual firms are Price Takers as they inherit         a horizontal demand-marginal revenue curve from         their industry.         1. A firm can not sell above market as products  are             identical and no one will buy higher than market.         2. There is no reason to sell below market as it would             mean less revenue and less profit.        Unit I. Review PC requires many independent       competitors selling virtually identical products. From chapter 22 on Understanding Profit
 A. Price is higher than average total cost so total is greater than total cost.       B. Cost includes a reasonable return on investment called "normal profit"           so under this definition of cost, any profit is an excess.      C.

Unit III. Review
Easy entry and exit of firms keeps profit near zero.

A. Suppose industry demand and supply yield an equilibrium price P at
which a firm's economic profit is zero.
1. Step 1 An increase in demand to D' causing economic profit.
2. Step 2 Market entry is relatively easy increasing industry
economic profit draws in new firms increasing supply
to S', lowering and economic profit disappears.
3. This automatic purely competitive adjustment causes long-term
economic profit for pure competition close toward zero.
4. Many feel a zero long run economic profit represents an ideal
economic model as all the company earns is a normal return
on investment.
 B. Application        Question Is Purely Competitive Adjustment Causing a        New Normal Or Is The New Normal Not New or Normal?     Beginning with economic expansion caused by WWII, demand for U.S. manufactured goods increased dramatically.  As a result, demand increase from D to D.' Profits maximization resulted. Thanks in part to Unions, these manufactures shared  their excess profits with unionized workers and wages increases spilled over to many nonunion workers. It took Germany, England and Japan many years to repair war damaged manufacturers and bring an end to U.S. manufacturer's monopoly power. Serious competition from foreign manufacturers beginning with  automobiles and steel increased supply causing Rust Belt Industries to lose their pricing power. This eliminated excess profits. Some industries incurred a loss as supply increased too much. Wage give backs began and many workers found themselves with stagnating wages. Companies used technology and outsourcing to be more competitive and maintain profit but this put pressure on wages. C. Examples     1. Post WW2 International Economic Competitive Adjustment     2.  Mark Blyth: Competitive Adjustment in European Market Area at 1 min          Competitive Adjustment Applied to Trumpism at 4 min 15 sec This also happened in the finance industry with competition coming from foreign banking and cheap Internet trading. Their attempt to increase D for their services with exotic products like derivatives has not worked out well as of 07/01/10. The bottom line is the standard of living enjoyed by U.S. citizens, their micro-lives, will grow more slowly as it is forced to share the wealth with people from around the world.  We may even have to give some back because of our energy dependence and recent decadence though increased production of energy with shale has lessened lessen this dependency. But we will still enjoy the highest  standard of living in the industrialized world.

Technology will continue to make our macro-lives better,
especially now that the Asians are contributing with their
R&D investments and collaborative competition in science
helped by the Internet has accelerate scientific advancement.
Plus gains from science are often cumulative and while not a
straight line upward they eventually make our macro lives better.
Think childhood diseases being cured and smart phones.

to be free and having enough money is a function of demand,
not supply. 08/12/11 updated 8/24/15

 D. Citizen Well-Being is More Important and Continually Grows.      1) Our society's stability has consistently increased US productivity           which is key to individual well-being. Think how the public safety net           has increased since the 1930's and the success of the federal           children's bureau. Think  economic distress in Russia, Europe,           and even Japan.      2) Scientific achievements have continuously added to citizen           well-being. Think public health, smart phones with loads of           free stuff not part of GDP or wages, streaming audio-           video, Gillette Stadium ... See Health Problems Solved      3) Personal Income which is a function of nature and Think nurture has           increased continuously if not always rapidly.  Russia, China,           and Europe's really slow recovery from the Great Recession.            Source Economic WellbeingSome Successful Companies Pay Everyone Well from economist.com 01/12/1 and 10/1/16   IV. Economic Analysis of Pure Competition       A. Competition is efficient.            1. Price settles where long-run ATC is at its lowest point indicating               goods are produced efficiently.            2. P = MR = MC indicating that resources are allocated efficiently as                \$'s spent by consumers (P) = the                \$'s received by producers (MR) = the                \$ cost of producers (MC) and                economic profit is zero.       B. Shortcomings           1. Spillover costs (pollution) and benefits (education) aren't properly               measured resulting in goods being over and under produced.               a. Government intervention was needed to lower automobile pollution.               b. Governments supports education with grants and inexpensive loan                   problems to students and colleges.           2. Monopoly power develops to negate Adam Smith's "invisible hand" of               competition which is required to assure that the purely competitive               adjustment occurs.           3. Eliminating economic profit makes it difficult for competitive firms to               afford expensive R & D and technology.           4. Economic Growth Volatility Unit IV. Review Price equal ATC where MR = MC with no profit V. Competitive Supply        1. A firm's MC curve is its short-run supply curve.        2. Industry supply is the horizontal summation of the firm's supply curves.        3.            analyzes the affect of long term supply on the efficiency of all industries. Unit V Review requires many independent resource suppliers competing with virtually identical factors VI. Other theories of the Competitive Model (from Wiki requires calculus)        A. Bertrand competition        B. Cournot competition requires calculus. Econintersect:  The U.S. slipped to seventh place in the ranking of economic competitiveness in the 2012. source the WEF (World Economic Forum).  Last year the U.S. ranked fifth.  The current result marked the fourth year of decline for the country that used to rule the competitiveness roost. More from econintersect.com. IMD Disagrees with its 2012 World Competitiveness Rankings Editor's comment on free trade  Free trade increase supply which forces price down resulting in some combination of lower profit or lower cost. Owners and managers  are good at maintaining profit and will try to lower the cost of materials, labor or overhead. Workers often bear the brunt of this process. Please
 VII. Readings       A. For a conservative view of competition Read Pure and Perfect"           Competition? from Capitalism Magazine By What Standard?            Part 5 in a Series of articles on Capitalism, Free-competition,           Antitrust, and Microsoft, By Richard M. Salsman       B. Present Day Application of the Purely Competitive Adjustment       C. Collaboration Competition is the New Competition      D. SWITZERLAND tops the latest competitiveness ranking from the World Economic Forum Best known for its annual shindig in Davos (a Swiss ski resort). It is closely followed by Singapore. Finland has topped Sweden to third place. Of the big emerging economies, China remains on top, with Brazil moving up. The most striking fall is the United States, which has dropped in the rankings for four years in a row. It is now seventh. The rankings are based on criteria such as institutions, infrastructure, financial systems, flexible labor markets, economic stability, innovations and public services. Plotting the scores against GDP per person reveals an unsurprising correlation: competitiveness brings wealth, but rich countries can most easily afford to provide the conditions for it. They can squander competitiveness too. Editors Note: Comparing the U.S. to anyone other than Germany and Japan is difficult as others are either small or developing. Plus we get a benefit from our being the world's currency which accrues from our being easily the world's strongest military and industrial nation. China assembles parts from all over Asia and has a way to go to be considered in this group. vvgg A Growing Nation from Turning Point in American History   depicts 19th American Capitalism at Work   Editor's Note: S&P 500 volatility depicts the problem of growth volatility systemic to capitalism. This puts pressure on monetary and fiscal policy especially as the first is better at controlling inflation and the later better increasing a lagging Aggregate Demand .
