I have recently been showing my AP and IB Econ classes the following New Yorker interview with Columbia Professor Tim Wu, the man who coined the phrase “net neutrality”. Wu shares his views on the “cycles” of competition in the communications industry, from radio, telephone and television in the 20th century to the internet and the “mobile web” today.

I find it a useful video for starting discussions about the pros and cons of perfectly competitive markets (represented by the “chaotic” period of any new communications technology) and imperfectly, more monopolistic industries (represented by the period later in the cycle of any communications technology when market power becomes concentrated among a few large firms).

Watch the video and pause it along the way to discuss some of the questions below.

Currents: Tim Wu on Communication, Chaos, and Control : The New Yorker

Discussion Questions:

1. Why are new communications industries often characterized by “chaos” in their early years? How did the internet industry reflect the perfectly competitive characteristics in its early days, or even 10 years ago?
2. How are consumers affected as communications industries go from “chaos” to control under big companies like Apple and Google?
3. How does the behavior of firms like Google and Apple demonstrate the concept of non-price competition?
4. Would the technology industry be more efficient if it were more competitive?
5. Can you envision a world in which all of our online activities are done through one company, i.e. the “Googlenet” or the “Facebooknet” instead of the “Internet”? Would that world be better or worse than what we have now? Why?
6. How is the communications industry today similar to the telephone industry 30 years ago? How is it different?
7. Tim Wu suggest that in the future there will be no internet. Discuss as a class what you envision as a possible successor to the internet.
8. If you had a time machine and could travel back to 1970, how would you try to explain to someone on the stree how we communicate with one another in 2011. How would you have tried to explain the internet and smart phones? Do you think someone from 1970 would believe your descriptions of products like Skype, like Google, like a phone you could watch movies on, like video chat, like “Google goggles”, etc…?
9. If someone from 40 years in the future arrived in 2011 and tried to explain to you how humans are communicating in 2050, do you think you would believe them?
10. Economist Joseph Schumpeter referred to capitalism as a system driven by a system of “creative destruction”. How does the history of the communications industry demonstrate the concept of “creative destruction”?

Imperfect competition in the News: After watching the video and discussion the questions with your class, go to Welker’s Wikinomics Universe and follow the link to the “Econ News” tab.  Browse the headlines from the various news feeds and look for articles that you think may be about non-price competition between firms in a monopolistically competitive or an oligopolistic market.

When you’ve found one good article, open your Diigo toolbar and add highlights to the lines in the article that you think demonstrate non-price competition between the firms described. Add one or two sticky notes using the Diigo toolbar, and when you’ve added your own thoughts, bookmark the article. Be sure to share it to your class’s group before bookmarking it so your classmates can view your highlights and sticky notes online.

If there is time left in class, log into your Diigo account and visit our class group. Read some of the highlights from your classmates’ articles and discuss with the people around you the various types of non-price competition described.

Competitively Priced Electricity Costs More, Studies Show – New York Times

The problem with monopolies, as our AP students have learned, is that a monopolistic firm, left to its own accord, will most likely choose to produce at an output level that is much lower and provide their product at a price that is much higher than would result from a purely competitive industry. A monopolist will produce where its price is greater than its marginal cost, indicating an under-allocation of resources towards the product. By restricting output and raising its price, the monopolist is assured maximum profits, but at the cost to society of less overall consumer surplus or welfare.

Unfortunately, in some industries, because of the wide range of output over which economies of scale are experienced, it sometimes makes the most sense for only one firm to participate. Such markets are called “natural monopolies” and some examples are cable television, utilities, natural gas, and other industries that have large economies of scale. (click graph to see full-sized)

Government regulators face a dilemma in dealing with natural monopolistic industries such as the electricity industry. A electricity company with a monopoly in a particular market will base its price and output decision on the profit maximization rule that all unregulated firms will; they’ll produce at the level where their marginal revenue is equal to their marginal cost. The problem is, for a monopolist its marginal revenue is less than the price it has to charge, which means that at the profit maximizing level of output (where MR=MC), marginal cost will be less than price: evidence of allocative inefficiency (i.e. not enough electricity will be produced and the price will be too high for some consumers to afford).

Here arises the need for government regulation. A government concerned with getting the right amount of electricity to the right number of people (allocative efficiency) may choose to set a price ceiling for electricity at the level where the price equals the firm’s marginal cost. This, however, will likely be below the firm’s average total cost (remember, ATC declines over a WIDE RANGE of output), a scenario which would result in losses for the firm, and may lead it to shut down altogether. So what most governments have done in the past is set a price ceiling where the price is equal to the firm’s average total cost, meaning the firm will “break even”, earning only a “normal profit”; essentially just enough to keep the firm in business; this is known as the “fair-return price”.

Below AP Economics teacher Jacob Clifford illustrates and explains this regulatory dilemma. Watch the video and see how he shows the effect of the two price control options on the firm’s output and the price in the market.

The article above examines the differences in the price of electricity in states which regulate their electricity prices and states that have adopted “market” or unregulated pricing, in which firms are free to produce at the MR=MC level:

“The difference in prices charged to industrial companies in market states compared with those in regulated ones nearly tripled from 1999 to last July, according to the analysis of Energy Department data by Marilyn Showalter, who runs Power in the Public Interest, a group that favors traditional rate regulation.

The price spread grew from 1.09 cents per kilowatt-hour to 3.09 cents, her analysis showed. It also showed that in 2006 alone industrial customers paid $7.2 billion more for electricity in market states than if they had paid the average prices in regulated states.”

The idea of deregulation of electricity markets was that removing price ceilings would lead to greater economic profits for the firms, which would subsequently attract new firms into the market. More competitive markets should then drive prices down towards the socially-optimal price, benefiting consumers and producers by forcing them to be more productively efficient in order to compete (remember “Economic Darwinism”?). It appears, however, that higher prices have not, as hoped, led to lower prices:

“Since 1999, prices for industrial customers in deregulated states have risen from 18 percent above the national average to 37 percent above,” said Mrs. Showalter, an energy lawyer and former Washington State utility regulator.

In regulated states, prices fell from 7 percent below the national average to 12 percent below, she calculated…

In market states, electricity customers of all kinds, from homeowners to electricity-hungry aluminum plants, pay $48 billion more each year for power than they would have paid in states with the traditional system of government boards setting electric rates…”

That $48 billion represents higher costs of production for other firms that require large inputs of energy in their own production, higher electricity bills for cash-strapped households, and greater profits and shareholder dividends for the powerful firms that provide the power. On the bright side, higher prices for electricity should lead to more careful and conservative use of power, reducing Americans’ impact on global warming (since the vast majority of the country’s power is generated using fossil fuels).

Here arises another question? Should we be opposed to higher profits for powerful electricity firms if their profits result in much needed energy conservation and a reduction in greenhouse gas emissions? An environmental economist might argue that if customers are to pay higher prices for their energy, it might as well be in the form of a carbon tax, which rather than increasing profits for a monopolistic firm would generate revenue for the government. In theory tax revenue could be used to subsidize or otherwise promote the development and use of “green energies”.

Whether customers paying higher prices for traditionally under-priced electricity is a good or bad thing depends on your views of conservation. But whether higher profits for a powerful electricity company are more desirable than increased tax revenue for the government are beneficial for society or not seems clear. If we’re paying higher prices, the resulting revenue is more likely to be put towards socially desirable uses if it’s in the government’s hands rather than in the pockets of shareholders of fossil fuel burning electricity monopolies.

Discussion Questions:

1. Why do governments regulate the prices in industries such as natural gas and electricity?
2. Why would a state government think that de-regulation of the electricity industry might eventually result in lower prices in the long-run?

This post was originally published on September 15, 2009. It is being reposted today for my year 2 IB Econ students, who are studying free trade and protectionism as part of Unit 4 of the IB Econ course.

US president Barack Obama made a speech directly to Wall Street today. In his speech, Obama reflected on the many lessons America has learned in the last year since the financial crisis began. He urged his audience of investors, bankers and brokers that

“Normalcy cannot lead to complacency,” Obama said. “Unfortunately, there are some in the financial industry who are misreading this moment. Instead of learning the lessons of Lehman and the crisis from which we are still recovering, they are choosing to ignore them.”

“They do so not just at their own peril, but at our nation’s,” the president added.

In addition to his warnings about the threat posed by overly risky financial markets to the US economy, President Obama expressed his commitment to free trade and “the fight against protectionism”.

Obama says:

…enforcing trade agreements is part and parcel of maintaining an open and free trading system.

The enforcement of existing trade agreements Obama refers to is his way of justifying a decision his administration made over the weekend that actually limits free trade between America and one of its largest trading partners, China.

Trade relations between two of the world’s biggest economies deteriorated after Barack Obama, US president, signed an order late on Friday to impose a new duty of 35 per cent on Chinese tyre imports on top of an existing 4 per cent tariff.

In his first big test on world trade since taking office in January, Mr Obama sided with America’s trade unions, which have complained that a “surge” in imports of Chinese-made tyres had caused 7,000 job losses among US factory workers.

So, in his speech today, Obama decries protectionism and calls for expanded trade and free trade agreements which are “absolutely essential to our economic future”. But only three days ago, he supported a blatantly protectionist measure aimed at keeping foreign produced goods out of America in order to save a few thousand American jobs.

Obama’s decision is a bad one for several reasons. As an economics teacher, I will turn firstly to a diagram for an illustration of the net loss to the American people of higher tariffs on imported tires:

The key point to notice in the above graph is that a tariff on imported tires results in a net loss of welfare in America. The blue area represents the increase in the welfare of tire manufactures (this could be interpreted as the jobs saved in the tire industry and the profits earned due to higher prices); the black areas, on the other hand, are welfare loss. Since all tire consumers in America pay more for their tires due to the 35% tariff, real income is affected negatively for the nation as a whole.

One effect of the protectionist policy the graph does not illustrate, and perhaps the most serious negative impact of the tariff on America, is the response the Chinese are likely to take to what they interpret as a violation of existing free trade agreements between the US and China.

“This is a grave act of trade protectionism,” Mr Chen said in a statement. “Not only does it violate WTO rules, it contravenes commitments the US government made at the [April] G20 financial summit.”

Beijing said it had requested WTO-sanctioned consultations with the US over Washington’s new duties on tyres. Yao Jian, a commerce ministry spokesman, said the duties were in ”violation of WTO rules”.

China said it would now investigate imports of US poultry and vehicles, responding to complaints from domestic companies.

The problems with protectionism are myriad. Clearly American consumers suffer through higher tire prices. In addition, Chinese manufacturers will see sales fall as their product becomes less competitive in the US market. According to the CCTV report below, as many as 9,000 workers in the Chinese tire industry will lose their livelihoods due to declining demand from the US. But the unforseen effects of the US tariff on Chinese tires is the retaliatory measures China will almost certainly take. If China imposes new tariffs on American automobiles and poultry, the scenario in the graph above will be reversed, and Chinese consumers will face higher prices, Chinese car and poultry producers will experience rising sales, while the American auto worker and chicken farmer will suffer.

Free trade tends to result in net benefits for economies that choose to participate in it. American tire manufacturers are certainly harmed by cheap Chinese imports; however, America as a whole benefits through cheaper goods, more consumer surplus, higher incomes in China and therefore greater demand for imports of products made in America. The road to protectionism is a dangerous path to take for the Obama administration. Justifying these new tariffs by claiming that they “enforce existing free trade agreements” is a political maneuver aimed at covering up the truth, which is that the Obama administration has sided with a special interest group to save a few thousand jobs and garner political favor at a time when 700,000 American jobs are being lost each month. By doing so, he is calling into question his own commitment to free trade, and harming America’s image as a global proponent of global economic integration.

Discussion Questions:

1. Why is the Chinese government so upset about a new tax on such an insignificant product as automobile tires?
2. “Self-sufficiency is the road to poverty”: Do you agree?
3. Some would say that it is a small price to pay for Americans to face higher prices for one product like tires in order to “save” 7,000 Americans’ jobs. Would you agree? Why or why not?
4. If 7,000 Americans were to lose their jobs due to free trade with China, what would we call the type of unemployment experienced by these workers? Is this the same type of unemployment experienced by the 700,000 workers who have lost their jobs each month during the last year of recession in the United States?

Consumers are interesting creatures to study. Economics offers us a unique set of tools for understanding the behavior of consumers in various markets. Elasticity is one of those tools, one which helps us understand how consumers will respond to the change in price of some goods more or less than others. Some of the questions about consumer behavior elasticity helps answer are:

• Why do governments place such huge taxes on cigarettes?
• Why did Apple cut the price of the new iPhone in half from the original one, despite the fact that it had so many new features?
• Why do movie theaters seem to raise their prices so steadily over the years, rather than doubling the price of tickets each year?

These and other questions can be answered by knowing something about the relative price elasticities of demand for the goods in question. Price elasticity of demand refers to the sensitivity of consumers to a change in price. For some goods, even the slightest increase in price will scare consumers away, while for others, price can go up and up and up and the quantity demanded won’t budge!

Here’s just one illustration of a good for which consumers are extremely sensitive to changes in price: Every autumn, around the city of Shanghai thousands of small farms harvest the Chinese watermelon, a small, green, juicy melon that looks and tastes the same regardless of which farm it came from. The farmers sell their melons to one of the hundreds of melon vendors who drive their big blue trucks into the city of Shanghai during about two weeks in October to sell the watermelons to the city folk who love their refreshing taste.

During the two weeks of the melon harvest, there are hundreds of blue trucks parked two or three per block all over the city. The hundreds of melon vendors sell an identical product, acquired at identical costs from thousands of farms using identical techniques for farming. In other words, the melon market in Shanghai during these two weeks is close to being perfectly competitive.

The price of melons is established through competition at something very close to the exact cost to the vendor of getting the melons into the city. Consumers know this, and therefore if one vendor tries to sell his melons for more than the equilibrium price, consumers will respond by buying NONE of that vendors melons. Conversely, if a vendor were to lower his price at all, rationally EVERY consumer would want to buy from that vendor, but since the price is already at the cost to the vendor, no vendor is able to lower the price without losing money. The outcome in the market for melons in Shanghai is that demand for melons is close to being perfectly elastic, meaning that consumers are completely sensitive to changes in price of watermelons.

Not all goods are like watermelons. In fact, for some goods demand is close to perfectly inelastic. Study the graph below, showing the relative elasticities of five different products, then answer the questions below in your comment!

Discussion Questions:

1. For which product is demand pefectly inelastic? Perfectly elastic? Unit elastic?
2. What relationship exists between relative slopes of demand curves and elasticity?
3. What are two characteristics of cigarettes that make demand for them inelastic?
4. What are two characteristics of heart transplants that make demand perfectly inelastic?
5. What are the characteristics of a good for which demand is perfectly elastic?

World Economic Forum – Latest Press Releases

The World Economic Forum, a group of researchers, leaders, educators, entrepreneurs and others with a vested interest in global economic performance, assembles an annual list of the world’s nations ranked according to “competitiveness”. This year, for the first time ever, the United States does not top this list, instead, Switzerland has been promoted to the status of global competitiveness leader.

What does this ranking really mean?

Competitive economies are those that have in place factors driving the productivity enhancements on which their present and future prosperity is built. A competitiveness-supporting economic environment can help national economies to weather business cycle downturns and ensure that the mechanisms enabling solid economic performance going into the future are in place.”

Competitivness means a nation posesses an evnvironment that leads to improvements in the productivity of its resources, most importantly labor. America, with record budget deficits, in the trillions of dollars, faces a future of tight budgets financed by government borrowing, which eventually means higher taxes and less ability for government to spend on public goods like education and health.

America’s demotion in the rankings is attributable to falling expectations about the country’s future growth potential rather than concerns about its current economic slowdown. Switzerland has also been in a recession for the last year, although due to targeted fiscal policies unemployment has remained low, near its level before the recession begain (around 4%).

The index used to rank countries is based on several factors:

The GCI is based on 12 pillars of competitiveness, providing a comprehensive picture of the competitiveness landscape in countries around the world at all stages of development. The pillars include Institutions, Infrastructure, Macroeconomic Stability, Health and Primary Education, Higher Education and Training, Goods Market Efficiency, Labour Market Efficiency, Financial Market Sophistication, Technological Readiness, Market Size, Business Sophistication, and Innovation.

Discussion Questions:

1. How can a nation’s labor productivity be improved by making policies aimed at improving three of the factors measured by the GCI identified above?
2. How does America’s gigantic budget deficit ($1.8 trillion) threaten its future ability to provide its citizens with the “pillars” identified above?
3. Does economic integration with the global economy improve or limit a country’s ability to achieve economic competitiveness? Explain your answer.

Now is that time of year when thousands of high school and college students across the world will be taking their very first economics course. Perhaps it will be a basic, high school introductory economics’ course, or perhaps an even more challenging AP or IB economics’ course. Or perhaps you are a freshman or sophomore in college taking an introductory macroeconomics or microeconomics course.

Whatever your situation, you will soon read that all introductory economic text book authors make the point, usually in their respective text’s first chapter, that a primary benefit of studying economics is that it aims to transform one into a more effective and influential citizen by enabling one to better understand and conclude on the economic positions and promises of those running for public office. The underlying logic is that a citizen or voter that is well-versed in basic economic principles will be a smarter citizen and more likely to vote for the political candidate or referendum that will deliver the greatest economic gain for the citizens of the locality, state, and/or nation. In fact, this “economics for citizenship” reason is why a growing number of states now require completion of a basic economics course as a requirement for high school graduation.

In my classroom, I informally call the study of economics “the 180 degree science” because as the student studies this social science for the very first time they often develop conclusions that are precisely the opposite (hence, the “180 degrees”) of what they had originally believed before taking their first economics course.

For example, here are two “180 degree moments”, which are applicable to the United States’ economy, that you may well learn in your first year economics’ course:

1. Pre-Econ Course or Uninformed View: “We don’t make anything anymore in America. America’s manufacturing prowess is in a state of constant decline. It seems like almost everything bought and used in the U.S. is made in China”

Post-Econ Course and 180 Degree View: Right before the recession hit in 2007, the U.S. was manufacturing approximately 2.5 times more in dollar value than China and is still today the largest manufacturer in the world. The dollar value of manufactured goods in the United States, restated for price level changes so the comparison is accurate, is up over 50% for the last 13 years ending in June of 2007, just prior to the recession! Yes, it is true that the U.S. has lost several million jobs in manufacturing over that same time period, but that is primarily due to rising manufacturing productivity (think machines & technology replacing humans), where the U.S. can now produce more valuable manufactured products than ever before freeing up those displaced manufacturing workers who now have found or must find employment in other more labor-intensive service-related businesses.

Moreover, the US has maintained its percentage share of rising global manufacturing product over that same aforementioned time period, whereas other countries, such as Japan and Germany, have actually decreased their percentage share of global manufactured product. More specifically, in 2006 U.S. manufacturing revenue, profits, exports, and productivity per employee reached their all time peak! Of course, with the current recession and the regression of the U.S. automobile industry, manufacturing levels are now below the levels of 2006. According to government statistics, manufacturing still accounts for slightly over a third of our economic activity and the U.S. will continue to grow in production value, although manufacturing will continue to decline as a percentage of overall economic activity as the United States is growing faster in services than in manufacturing.

2. Pre-Econ Course or Uninformed View: “It is patriotic for U.S. citizens to “buy American” so that we can help our own economy. When we buy foreign products (i.e., exports), in lieu of American products, we hurt our U.S. economy as we lose American jobs and incomes. I hope the recently passed stimulus bill monies will be spent entirely on U.S. products and services.”

Post-Econ Course and 180 Degree View: The U.S. will benefit the most economically if Americans buy what they consider to be the very best product, in terms of price and quality, regardless of whether it is a foreign-produced product or an American-produced product. One of the greatest “ah-ha” moments in all of economics is when an economics’ student or citizen learns for the first time that every time a U.S. buyer purchases a foreign product (i.e., an “import”) that those same U.S. dollars spent on the foreign product circle back to a U.S.- based company, not a foreign company. Yes, I am telling you that when you (or Wal-Mart, for example) buy Chinese shirts, your same U.S. dollars spent quickly end up in the hands of, say, an Apple, Microsoft, IBM, or General Electric to maintain or increase U.S. employment, profits, and stock prices!

Let me try to explain this concept in more detail so that I may actually be able to convince you of this amazing “180 degree” revelation. I always say the more accurate slogan should be “Buying American is Un-American”, since it creates a weaker America!

Let’s say that the United States (we’ll say Wal-Mart) decides to buy some shirts costing $400 from a Chinese shirt manufacturer, in lieu of buying similar shirts from, say, a shirt manufacturer in Elon, North Carolina (USA). The first key point is that when Wal-Mart buys the shirts from China for $400 it can only pay China with US dollars. Why? Because Wal-Mart has only US dollars! It has no Chinese currency (Yuan). It literally drains its bank account of US dollars that are transferred/paid to China! The second key point is that when China receives that same $400 US dollars for the shirts, China cannot, unfortunately, spend any of the $400 in its own economy since only the Yuan is accepted as a medium of exchange in China! China is now forced to either throw the U.S. currency away (not advised!), or immediately spend the money back to the USA (advised!).

In summary, China has initially traded a product (shirts!) for paper (US dollars!), and those US dollars cannot be spent in China. For China to receive any value at all for the shirts it sent to America, China must now spend the $400 back into the US economy for, say, a few i-Pods from Apple (USA). Cutting through to simplicity, in essence, it’s almost as if Wal-Mart (USA) just paid Apple (USA) $400 directly! Yes, the economic “punch line” is that all spending by the domestic nation on foreign products (imports), in turn, are spent immediately back to the domestic nation increasing or maintaining that domestic nation’s employment, income, and standard of living.

And, yes, let’s not forget about that Elon, North Carolina shirt maker that did not get the original $400 from Wal-Mart in our above example! Any good economy promotes competition and I will be excited to see if that North Carolina shirt manufacturer can “raise their game” (increase productivity and/or quality), and hopefully get the next shirt contract from Wal-Mart! If not, well, that North Carolina firm may just have to close down. But remember the key point is that the $400 spent for the Chinese shirts went to Apple, in lieu of the Elon, North Carolina shirt manufacturer. If Wal-Mart would have “bought American” by buying from the Elon shirt manufacturer, even though the Chinese shirts were preferable, Wal-Mart would have prevented the more effective U.S. business (Apple, in this example) from getting your U.S. dollars by giving them to the less efficient Elon manufacturer. In short, you would have contributed to American inefficiency and mediocrity, hurting our country! And that is un-American!

Now, you may be thinking the following if you have a little economics’ background: “But the US has a growing trade deficit with China, so China may not immediately buy those i-Pods from Apple for $400. And, you are correct, but that is also not a problem for either the United States or China. What China is really doing right now is deciding to temporarily save or invest a minority percentage of their US dollars received from U.S. import purchases. Said another way, China is not buying as many US i-Pods as the US is buying Chinese shirts and, of course, we call that situation the US trade deficit which immediately seems to speak “problem”. But it is really not as big a problem as most people think! China is still spending their “saved” US dollars back into the US economy, but in different ways. China is saving and investing some of those US dollars directly into the United States economy by building plants in America, buying US stock to fund American companies’ expansions, and temporarily saving some of their dollars, for future US purchases, by buying US bonds to help the US government pay for other US government initiatives necessitating borrowing. Eventually, China will sell these US bonds and be forced to use those U.S. dollars to buy those i-Pods or build more plants in America to employ more Americans!

I decided to highlight this particular “180 degree moment” because of the fact that the recently passed $800 Billion U.S. stimulus bill has some “buy American” provisions within it. Based on my intuition, I believe that over 95% of adult Americans believe that these “buy American” clauses somehow help our economy more so than if the stimulus bill was silent on “buy American”, thus allowing stimulus money to be spent on foreign-produced products as well. Yes, it is an economic principle that if U.S. citizens “buy American” driven solely by patriotism (and not because they think the product is superior) the American economy actually becomes weaker as the U.S. dollars spent out of patriotism on that American company are, therefore, unintentionally withheld from another more efficient and deserving American company.

In summary, when citizens of any country in the world buy the product that is best for them based on a combination of quality and price, they will be taking the most patriotic action possible to help their own country they love so much! If a domestic citizen sees the foreign product as a better alternative to the domestic product, buy it! Your money spent will immediately find its way back through the “trade loop” to another business within your country!

Of course, this is why all economists from around the world know that international trade, and not protectionism, helps a country’s standard of living and promotes efficiency and rising standard of livings!

Well enough for now. I could go on and on with more 180 degree moments relating to areas such as standard of living, unemployment, the minimum wage, gasoline taxes, and many others. But we’ll discuss some of those in class and I will cover others through this blog site. For now, I just really hope you look forward to and work hard in your economic course so that, you too, will become a more informed and influential citizen as you begin to see your nation’s economy, and our global economy, in a whole new light!

Discussion Questions:

1. Do you believe that politicians will promise and enact policy that seems on the surface to be beneficial to a nation, but are actually harmful to that nation?

2. After reading this blog do you begin to see how the huge declines in manufacturing employment are more driven by leaps in productivity (machines and know-how)? How else could we be producing more manufacturing value each year if employment is decreasing?

3. What would happen to a nation’s “standard of living” if the government passed a law requiring its citizens to only buy their own domestic products? Why?

4. Do you personally believe you will make your own country’s standard of living grow the fastest if you buy the best product available, whether an import (foreign) or a domestic product?

One of the greatest “ah-ha” moments in all of economics is when an economics’ student or citizen learns for the first time that every time a domestic buyer purchases a foreign product or import that those same U.S. dollars spent on the foreign product go to a U.S.-based company, not a foreign company. Yes, I am telling you that when you (or Wal-Mart) buy Chinese shirts, your same U.S. dollars spent quickly end up in the hands of, say, Apple, Microsoft, Garmin, or General Electric to increase U.S. employment, profits, and U.S. stock prices!

I decided to write this particular blog because of the fact that the recently passed $800 Billion U.S. stimulus bill has some “buy American” provisions within it. Based on an intuitive hunch, I believe that over 99% of adult Americans believe that these “protectionist” clauses somehow help our economy. Yes, the vast majority of U.S. adults believe that it is clearly more advantageous to “buy American” in order to keep the money or wealth within America in order to increase U.S. employment, profits, and U.S. stock prices. In true economic fact, however, if U.S. citizens “buy American” solely out of patriotism (and not because they think it is a superior product) they actually HURT America because the U.S. dollars spent out of patriotism on that American company are, therefore, unintentionally withheld from another more efficient and deserving American country via the “trade loop”.

Let me try to explain this “trade loop” in more detail so that I may actually be able to convince you of this amazing “180 degree” revelation: “Buy American” is Un-American

Let’s say that the United States (we’ll say Wal-Mart) decides to buy many shirts costing $400 from a Chinese shirt manufacturer, in lieu of buying those same shirts from, say, a shirt manufacturer in Elon, North Carolina (USA). The first key point is that when Wal-Mart buys the shirts from China for $400 it can only pay China with US dollars. Why? Because Wal-Mart has only US dollars! It has no Chinese currency (Yuan).

China is now forced to either throw the U.S. currency away (not advised!), or immediately spend the money back to the USA (advised!).

In summary, China has initially traded a product (shirts!) for paper (US dollars!), and those US dollars cannot be spent in China. For China to receive any value at all for the shirts it sent to America, China must now spend the $400 back into the US economy for, say, a global positioning system (GPS) from FleetMatics out of Waverly, Massachusetts (USA). Cutting through to simplicity, in essence, it’s almost as if Wal-Mart (USA) just paid FleetMatics (USA) $400 directly!

Yes, the economic “punch line” is that all spending by the domestic nation on foreign products (imports), in turn, are spent immediately back to the domestic nation increasing the domestic nation’s employment, income, and standard of living.

And, yes, let’s not forget about that Elon, North Carolina shirt maker that did not get the original $400 from Wal-Mart in our above example! Any good economy promotes competition and I am excited to see if that North Carolina shirt manufacturer can “raise their game” (increase productivity and/or quality), and hopefully get the next shirt contract from Wal-Mart! If not, well, that North Carolina firm may just have to close down. But remember, the key point, the $400 spent for the shirts went to Fleetmatics in Waverly, Massachusetts, in lieu of the Elon, North Carolina shirt manufacturer. If you would have “bought American” even though the Chinese shirts were preferable, you would have prevented the more effective U.S. business in Waverly from getting your U.S. dollars by giving them to the less efficient Elon manufacturer. In short, you would have contributed to American inefficiency and slowing productivity, hurting our country! And that is un-American!

Now, you may be thinking the following if you have a little economics’ background: “But the US has a growing trade deficit with China, so China may not immediately buy that GPS system from FleetMatics for $400. And, you are correct, but that is also not a problem for either the United States or China. What China is really doing right now is deciding to temporarily save or invest a minority percentage of their US dollars received form U.S. import purchases. Said another way, China is not buying as many GPS’ as the US is buying shirts and, of course, we call that phenomenon the US trade deficit which immediately seems to speak “problem”. But it is really not as big a problem as most people think! China is still spending their “saved” US dollars back into the US economy, but in different ways. China is saving and investing some of those US dollars directly into the United States economy by building plants in America, buying US stock to fund American companies’ expansions, and temporarily saving some of their dollars, for future US purchases, by buying US bonds to help the US government pay for other US government initiatives necessitating borrowing. Eventually, China will sell these US bonds and be forced to use those U.S. dollars to buy that GPS system or build more plants to employ more Americans!

In summary, when citizens of any country in the world buy the product that is best for them based on a combination of quality and price, they will be taking the most patriotic action possible to help their own country they love so much! If a domestic citizen sees the foreign product as a better alternative to the domestic product, buy it! Your money spent will immediately find its way back through the “trade loop” to another business within your country!

Of course, this is why all economists from around the world know that international trade, and not protectionism, helps a country’s standard of living and promotes efficiency and rising standard of livings!

This week in AP Microeconomics students get to play online games, watch movies, and compete with their classmates in strategic competitions in which there are proud winners and sad losers. That’s right, we’re studying oligopoly!

What makes oligopolistic markets, which characterized by a few large firms, so different from the other market structures we study in Microeconomics? The answer is that unlike in more competitive markets in which firms are of much smaller size and one firm’s behavior has little or no effect on its competitors, an oligopolist that decides to lower its prices, change its output, expand into a new market, offer new services, or adverstise, will have powerful and consequential effects on the profitability of its competitors. For this reason, firms in oligopolistic markets are always considering the behavior of their competitors when making their own economic decisions.

To understand the behavior of non-collusive oligopolists, economists have employed a mathematical tool called Game Theory. The assumption is that large firms in competition will behave similarly to individual players in a game such as poker. Firms, which are the “players” will make “moves” (referring to economic decisions such as whether or not to advertise, whether to offer discounts or certain services, make particular changes to their products, charge a high or low price, or any other of a number of economic actions) based on the predicted behavior of their competitors.

If a large firm competing with other large firms understands the various “payoffs” (referring to the profits or losses that will result from a particular economic decision made by itself and its competitors) then it will be better able to make a rational, profit-maximizing (or loss minimizing) decision based on the likely actions of its competitors. The outcome of such a situation, or game, can be predicted using payoff matrixes. Below is an illustration of a game between two coffee shops competing in a small town.

As illustrated above, the tools of Game Theory, including the “payoff matrix”, can prove helpful in helping firms decide how to respond to particular actions by their competitors in oligopolistic markets. Of course, in the real world there are often more than two firms in competition in a particular market, and the decisions that they must make include more than simply to advertise or not. Much more complicated, multi-player games with several possible “moves” have also been developed and used to help make tough economic decisions a little easier in the world of competition.

While Game Theory can be useful in predicting firm behavior in oligopolistic markets, believe it or not that is not its most useful application developed. In fact, would you believe me if I told you that Game Theory may be precisely what saved the world from nuclear holocaust during the 20th Century? It’s true. The US government employed Game Theory to avert annihilation by nuclear attack from the Soviet Union during much of the 20th Century. This video tells the story!

Chicago, Seattle first markets to get instant Starbucks — chicagotribune.com

I consider myself a Seattleite. I discovered the joy of drinking coffee in the home of Starbucks, Tully’s, Seattle’s Best, and countless local coffee shops that inhabit every corner of the rainy city. To me, the experience of drinking a latte, machiato, cappuccino, or simply a “coffee of the week” encapsulates the smells, soft decor and friendly greetings from the barista at my favorite coffee shop. Living overseas, I have turned to Starbucks over and over for a taste of Seattle and a feeling of home.

There is no denying that the Starbucks experience is one that does not come cheap. Here in Switzerland, a grande latte, my drink of choice, sets the consumer back nearly $7. In an economic downturn such as that the US and the rest of the world are experiencing right now, such expenses are often the first to be reduced by cash strapped consumers. In fact, I recently began bringing a thermos of homemade coffee to work every day, rather than stopping at the Starbucks at the train station as I had done for several months not long ago.

Starbucks, which recently announced the closure of hundreds of its locations around the world, is actually expanding its product line while simultaneously closing down shops. It may not be in the way you expect, though. Soon, I’ll be able to get my $7 cup of coffee for as little as $1, it will just come in a different form:

Starbucks Corp. will launch its new instant coffee product next month in Chicago and its home turf of Seattle, with a full-scale, national offensive set for the fall.

Starbucks on Tuesday formally unveiled the new product, called Via Ready Brew. It will be available in Starbucks retail outlets in the Chicago and Seattle areas on March 3, Howard Schultz, the company’s chief executive, said in an interview with the Tribune.

Instant coffee from the king of gourmet blends? Sounds suspicious. Well, it’s all about economics, you see. Starbucks coffee is a normal good, one for which demand falls as incomes fall, as evidenced by falling sales at its coffee shops around the world. In order to maintain its customer base even as incomes fall, a company like Starbucks must expand its product line to include inferior products, or those for which demand increases even as incomes fall. Clearly, instant coffee is viewed as an inferior product, due to its significantly lower price and reputation of poor quality.

Furthermore, Starbucks’ new product is in response to increased competition from lower-end fast food chains that traditionally did not compete in the coffee market, but recently have begun offering various blends and varieties of coffee to the price-sensitive coffee consumers, further harming business at Starbucks’ higher end coffee outlets.

Via marks Starbucks second announcement this month of a cheaper menu alternative, as the famous coffee chain struggles in a weak economy. Starbucks is also now selling pairings of coffee and breakfast offerings for $3.95.

Starbucks’ troubles have occurred at the same time value-oriented fast-food chains, particularly Oak Brook-based McDonald’s Corp., have thrived. McDonald’s owes part of its success to improving the quality of its basic coffee, and expanding into new drinks like iced coffee, and, more recently, flavored specialty coffees such as lattes and cappuccinos.

Still, Schultz said McDonald’s coffee offensive hasn’t really affected Starbucks: “We have a lot of respect for McDonald’s as a company. But we have not seen any significant issues with McDonald’s share of the coffee business affecting Starbucks.”

McDonald’s offers “a different product, a different value proposition,” he said. In fact, Schultz said McDonald’s should expand the overall coffee market, thus leading some customers to “trade up” to Starbucks.

Despite the CEO’s claims that Starbucks and McDonald’s coffees are “different” products, it is clear by his firm’s decision to expand into the instant coffee market that Starbucks is concerned about the loss of customers to lower-end coffee retailers.

The theory of firm behavior as studied in AP and IB Economics teaches us that firms in oligopolistic or monopolistically competitive markets, such as that for coffee shops in the US, tend to compete using non-price methods such as product differentiation and advertising. Rather than slashing the prices of all of its coffee in the face of a recession and falling consumer incomes, Starbucks has instead diversified its product line to include lower end options for consumers whose sensitivity to price and demand for gourmet coffee have been adversely affected by the weak economy.

Professor Preston McAfee on Price Discrimination

(you must have RealPlayer to view this video. Mac users can download it here)

CalTech Economics professor Preston McAfee is an expert on prices. His research spans three decades and examines the pricing behavior of firms in various market structures. In the lecture linked above the professor shares several examples of firms practicing price discrimination. I was surprised to see that many of the examples he discusses are ones that I have been using in my own lectures on price discrimination for the last few years.

McAfee presents a mathematical formula for monopoly pricing, which no AP or IB text that I’ve seen has included:

Monopoly Price = [PED/(1-PED)] x MC where PED is the price elasticity of demand of the customer and MC is the firm’s marginal cost of production.

The basic idea is that the more inelastic the customer’s demand, the higher price the monopolist should charge over its marginal cost. The implication, therefore, is that a monopolist prefers to charge higher prices to customer’s whose demand is inelastic and lower prices to customers who are “price sensitive” or whose demand is elastic. The charging of different prices to different consumers for the exact same product is what economists call price discrimination.

McAfee begins talking about price discrimination at minute 8:44 in the video. His examples include:

• Movie theaters: Charge different prices based on age. Seniors and youth pay less since they tend to be more price sensitive.
• Gas stations: Gas stations will charge different prices in different neighborhoods based on relative demand and location.
• Grocery stores: Offer coupons to price sensitive consumers (people whose demand is inelastic won’t bother to cut coupons, thus will pay more for the same products as price sensitive consumers who take the time to collect coupons).
• Quantity discounts: Grocery stores give discounts for bulk purchases by customers who are price sensitive (think “buy one gallon of milk, get a second gallon free”… the family of six is price sensitive and is likely to pay less per gallon than the dual income couple with no kids who would never buy two gallons of milk).
• Dell Computers: Dell price discriminates based on customer answers to questions during the online shopping process. Dell charges higher prices to large business and government agencies than to households and small businesses for the exact same product!
• Hotel room rates: Some hotels will charge less for customers who bother to ask about special room rates than to those who don’t even bother to ask.
• Telephone plans: Some customers who ask their provider for special rates will find it incredibly easy to get better calling rates than if they don’t bother to ask.
• Damaged goods discounts: When a company creates  and sells two products that are essentially identical except one has fewer features and costs significantly less to capture more price-sensitive consumers.
• Book publishers: Some paperbacks cost more to manufacture but sell to consumers for significantly less than hard covers. Price sensitive consumers will buy the paperback while those with inelastic demand will pay more for the hard cover.
• Airline ticket prices: Weekend stayover discounts for leisure travelers mean business people, whose demand for flights is highly inelastic, but who will rarely stay over a weekend, pay far more for a roundtrip ticket that departs and returns during the week.

McAfee also goes into a fascinating discussion of price dispersion which is essentially a theory of oligopoly pricing. All Econ teachers should watch this video and find examples of price discrimination and oligopoly pricing that they can incorporate into their own class.
