Microsoft and Monopoly
Microsoft is the most famous company in the world, everyday everyone can see it products everywhere, and where is very less other's company's product can effect Mocrosoft's market share. so the situation caused anti-monolopy to microsoft. but I think it is unfair situation, because microsoft's products are perfect and useful, and other company's products cannot compete with microsoft. And it is not a black market, I think at the same to said anti-monopoly to microsoft we should foucs on other company and give them some support to help them make a good product to compete with microsoft, thur the market will became a competive market.

The Black Market and the Oil Price in China
The Chinese government set a price ceiling of gasoline, but the price which was set by Chinese government is lower than cost price. Because of this situation, the petroleum companies decrease the supply, but the price still at that price, therefore, many car and track cannot get gasoline. Now, there is a black market appeared, some people see that situation, and thought it was a chance to make money. First, they went to a gasoline station to buy much gasoline, than when the station run out of oil, they bring the gasoline that they brought before and sell the gasoline the station or drivers at a much higher price.
The government had to free the price of gasoline; it is the most effective way to solve the problem. Because if the oil companies can sell the oil at a higher price and get more benefit, they will produce more oil, so the people who buy and sell gasoline illegal does not have any benefit, and the situation will be stopped.
Pollution and Airline Code share
As we know, the airplanes make a big air pollutions, there are so many flights in the air and pollute the air. But there is a strange situation, the seats in plane is hard to be taken fully in every flights, and some airlines have the same lines, so there are many planes in the air, and there are not fully being taken by passengers. So the code share can reduce the air pollution, and decrease the cost of each airline, and they can get more benefit and do not need more pollution permits.
For example, I took the flight CA982 from New York to Beijing, at the same time the flight is UA4451, even this the plane was not full, imagine if there are planes to fly this line, there will be more most of Air China and United, and there will be more air pollution.
Market Share in Our Life
In our daily life, there are many famous brands around us, and in a same field, there are also few famous brands, they have the market share almost equally, because of this situation, I believe the market share offer a variable choice to our life, if there are more pieces of market share. And the variable choice offer many chance to save many, at the same time we can get more goods.
For example, in Marietta there are several pharmacies, if I want to buy a bulb, I will to go to each pharmacy, and try to find the cheapest one. Another reason is that there is a competition between each pharmacy, so the price of goods will be fine and cheap. There are more pharmacies means there are more goods to sell. Because each pharmacy is different, each one has its feature, so they can offer different goods and we can buy more goods than there is less pharmacy.
Grain from Trade and International Trade Competition
The gain from trade means people can get more benefit than do a job or a produce alone. But, there is a issue between countries, all the countries want to get the most benefit through trade with other countries, in the other side, all the countries afraid more countries are stronger than themselves, and all the countries also want to restrict the trade of other countries. So the big countries always make trade with same countries which are have many sources and need the protection of big countries. For example, China like to trade with African country, China sells many kinds of goods and weapons, and get many sources from those countries. In the United Nations, the trade between China and African Country can let they help each others, like China can get ballot from African countries, and China also can protect the benefit of African countries.
Chinese Style Price Discrimination
There is unique price discrimination in China. In many Chinese shopping malls, before you go shopping there, you have to learn how to make discount positively by yourself, because in there shopping malls, the sellers would not tell you the true price of the good and the original price which they said is much higher.
the price you buy the goods is depend on your skill to make discount, if you have a better skill and experience than other’s, you can get the same good at a lower price, so it is a different kind price discrimination.
How to avoid this discrimination? There is most useful way, it’s that you must have your willingness to pay, and you insist the price that you can accept of a good.
For example, in Silk Street which is a famous shopping mall in Beijing, and in the mall you have to make discount to every goods, if not the discrimination are happen on you.

Powerful Externalities of a Giant Natural Monopoly in a Free Market
Today on the abc World News Tonight with Charles Gibson announced that Exxon Oil has announced the largest quarterly profits of any corporation ever - 11.7 billion dollars. Shell Oil followed with 11.5 billion for the quarter. Hearing that news none of us would wonder where that profit came from - we paid for every penny at the pumps. However, as the commentator explained, Exxon made its profit long before the oil was even refined into gasoline. They made it by raising the cost of the crude oil.
Exxon and other oil drilling companies are part of a small competitive monopoly that sets the prices and to a large degree controls the markets of many other goods and manufacturing. The commentary explained that oil production in the Middle East had slowed after the US invasion of Iraq (It is just getting back and increasing now.) The decrease in production by one supplier began the manipulation of the market by the other monopoly participants. By slowing oil production or as the commentary described by conducting repairs on oil drilling or broadcasting concerns that oil production may be curtailed because of the continued aftermath of major storms in the Gulf of Mexico, the consuming countries were willing to pay a premium price on oil to assure their supply.
The oil drilling market is not easily entered. Many oil rich lands are off limits to new and old companies because of governmental and political restrictions (e.g., in Russia and Venezuela), because of conservation concerns (in the coastal waters and in Alaska) and because of natural barriers (e.g., drilling by the North Pole although there is already interest by oil companies in the sea beneath the melting northern icecap). Therefore the monopolist oil companies have been able to set the price and get what they ask.
But there is another side to the story. The news commentary described what happened during the oil crisis in the 1970's when President Carter urged all Americans to conserve energy. For a while Americans bought smaller cars and turned down the heat. But the oil crisis did not last long and soon we all went back to consuming the cheap supply of energy. This time is different. There is no expectation that the oil crisis will end soon. The longer the prices stay high the more lasting the effects. Americans are already driving less, taking more public transportation, working at home for some days per week, buying “green” and seeking products and designs that conserve energy. These changes are not temporary because they are effecting a shift in production and industry. One example is the Toyota factory that had opened in Louisiana and was prepared to make trucks has now retooled to make hybrids. American auto manufacturers have done the same. So that were the energy crisis to end in the next few months, the shift that has taken place would not simply return to the old ways. Economists call this demand destruction, in which changes in the economy creates a shift in consumer behavior that destroys interest in old products. The process is a natural phenomenon in the technology industry in which new devices quickly make old ideas obsolete. With the oil crisis, the destruction of demand has made “going green” the new chic.
Coase Theorem at Work in a College Town
The Coase Theorem states that a free economy will find private solutions to difficult economic conflicts. This article appeared a few years ago but what it describes is happening right now in New Haven, Connecticut where I live. The activity is an example of a creative solution to a complicated problem - without government interventions. The article describes a variation on car-rentals; charges by the hour especially in big cities or near airports and business centers.
What is happening in New Haven, the city where Yale University is, involves the growing problem of traffic congestion and scarce parking places. The university had banned student cars from university lots, especially after new construction took up several parking lots. Students and their parents of course complain. And city businesses miss out because the carless students do not buy big items because they cannot carry them to their dorms. However, the city was not interested in subsidizing student parking even though the university is a big part of the economy. The city also has a shortage of parking spaces and students would be leaving cars unused for long periods of time in parking spaces needed for consumers of city businesses.
A few enterprising students formed a business “Pick-Ride-Drop” nicknamed PaRDEE. The idea is that the business makes a few cars available to students to rent for an hour or more to shop or get to the train station. They are charged by the hour and an extra fee if they do not bring the car back to the same lot where they picked it up. There are drop off places at ten spots around the city, including the train station, the grocery stores and shopping district, the medical center, and several business centers. The students call ahead to reserve a car at a pickup place and then drop it off with the keys in a special pouch for the next driver. The business began with 10 cars and now there is a group of 39. The market has opened to employees of the university and several allied businesses.
The Coases theory is evident in the following. The business would not have worked if the owners had to pay the exorbitant parking and the students would not have purchased the cars if the parking costs had been passed down so Yale designated a number of spots just for the cars in exchange for happier students and parents. The city also agreed to waive the street parking meters for those cars in exchange for more reasonable numbers of student cars. The students have to plan ahead but for very reasonable rates get to have car transportation when needed. The fees go to car repair and gas. As gas prices increased the rates have also climbed but are still acceptable.
The most recent development is the addition of a bicycle fleet operating on the same principle for those who are thinking green. In a recent local paper article one of the owners commented that the shared rides and cars is a practice that is more common in Europe but workable in the American city. The organization is planned as an excludable and rivable product, making a private business.

Flying Without Luggage
FedEx and UPS are the two most promising ways to go in shipping luggage, but the trouble is, how soon do you send it. In choosing this option, it would be necessary to pack well in advance and have your luggage well on its way at least five days before your expected arrival. And all for comparable cost to what you are paying to check the luggage in the first place. The biggest advantage lies in the idea that shipping the luggage gives you the option to use delivery confirmation and insurance on lost luggage. Airlines however, don't guarantee anything lost in route.
So after contacting your hotel to assure they accept early arrival luggage, making sure you haven't packed any "dangerous goods", like aerosol spray, perfume, cologne and nail polish remover, and preparing well in advance, the question that lies is, "Is it worth it?" Would the benefits from shipping your luggage outweigh the extra $25 per extra bag? I say, pack lighter, shoot for one suitcase and a carry-on and you're set.
Prices of Food and Gas Take a Toll in Asia
While oil prices were rising, most others products prices were rising. Oil is most important public products in the world because most factory and transportations using oil. Therefore, the rising of oil prices strongly impact to rising of other products prices. Some countries reduce tax of oil to block inflation. However, that was not a solution. They couldn't block inflation. Now, the oil prices are dropping. Then we can suppose that other products prices will be dropped.

Trouble before the Olympics
Chrysler Needs Back Up
Squid and Oil Face a Common Enemy
The same control is not true for the fishing industry. As the cost of fish and squid increase, consumers can find ready substitutes - steak or vegetarian meals. Fish is rarely an indispensable commodity for most consumers of the world. Oil on the other hand is not replaceable - at least not yet and not until there is a viable and reliable cheaper energy source and the technology to use it.
Solar power and wind power are two potentially viable sources that future technology may bring into reality. Both are public goods - that is nonexcludable and nonrival in their specific form although a levied cost may make them artificially scarce goods, limiting access to those willing to pay.
For now oil is the primary source of energy for transportation and much of industry. As the demand continues, the "overfishing " of the fossil fuels as well as the associated pollution will continue to threaten the environment and political stability of the world.
One of the hot issues in the upcoming election is the management of the high cost of oil (driven up by both the manipulation of supply by the oil producers and by the surge in demand by developing nations like China and India which have greatly increased their oil consumption). Two different solutions have been proposed. One by McCain is to relax the government regulation that prohibits drilling in protected lands and coastal areas of the United States. The Democratic proposal is to reduce the demand for oil through government regulation that forces auto manufactures to increase the engine efficiency of cars and and increase the development of hybrid and electric cars. Notably in the free market economy, consumers themselves have an impact on the crisis by buying smaller cars, using public transportation, conserving energy in the heating and cooling of their homes, and driving less. Although government regulation is necessary, the consumer behavior is also an important element in decreasing over use and unacceptable levels of environmental impact.

Externalities in Rubber Ducks
The chemical contamination in manufacturing represents an externality. The question of whether it can be observed directly or not is still debated. Although the amount of lead and phthalates can be measured, the amount of harm they impose on the consumer is what is debated. Those in favor of regulation site studies that show exposure to these chemicals produces negative health effects in animal. The manufacturers and their lobby argue that the scientific evidence is inconclusive. (A National Public Radio program compared the current debate over these chemicals with the earlier one that focused on saccharine as a carcinogen.). Therefore regulation of this chemical will need to focus on the original action (page 456 in Chapter 19) rather than on the outcome. That is, what is being regulated is the presence of the chemical itself and not the health problems which remain uncertain and hard to measure.
There would be little incentive for manufacturers to change their use of this chemical and it would not be possible to depend on the market to regulate it since consumers have no way of telling from looking at the product whether it is contaminated or not. Therefore governmentregulation is required to control the negative externality of the rubber duck and all toys.
The Optimal Polution in a Command Economy
Part of the Chinese difficulty comes from a command market economy in which the public serves the wishes of the government and has no power to force regulation of negative externalities on their own behalf. Private enterprise is similarly limited and so the regulation that comes from a market economy is also missing.
As the article points out, the same factors that got China into the pollution bind are those being used to try an emergency fix. The government ordered that factories be dissembled and moved in their entirety to the farmland far from the city. The cost was considerable both in lost production, manpower, and resources. However, the benefit to the country in terms of world perception and success in hosting the Olympics was viewed by the central government to outweigh the cost. As the article points out, the efforts may be too little too late to effectively control air quality.
The effect of the pollution in China, the level of which bypassed that considered optimal in the West, now will have global effects through the reactions of individual athletes. The negative externalities have increased dramatically because of the unique circumstances of the Olympic games. But they are not easily eliminated or controlled. The Chinese government has viewed pollution as an unavoidable consequence of economic growth and ignored pollution as a side effect. Now the interest has changed and decreasing pollution is an ultimate goal. In a command economy the optimal pollution is whatever the government decides at whatever cost it takes.

Apple’s 3rd Quarter profit jumps 31%
Apple Inc’s conservative outlook tends to usually make them shoot low in their predictions for 4th quarter earnings. Apple only predicts a profit of $1 per share on $7.8 billion in sales, well short of Wall Street expectations. Through the plagues of expectations in the stock market Apple has been one of the strongest competitors, while still making profit when the economy is down. In the future, investors predict that Apple’s gross margin will drop. In response to this accusation, Apple Inc. noted that margin was actually better than expected, helped by better commodity prices and stronger sales of higher margin products. Oppeheimer forecasts even lower margins in the 4th quarter, tied in part to the launch of the undisclosed new products.

Amazon remains resilient as Economy weakens and gas prises rise
At the end of the quarter, June 30th, Amazon earned $150 million, and in the same quarter last year earned $78 million. The company’s revenue took a leap and climbed 41% to $4.08 billion, including a 35% leap in North America. The company’s net cost climbed to $128 million from $75 million last year.
The reasonably confident internet retailer has increased its sale forecast for the rest of the year to a range of $19.35 billion to $20.10 billion.
Facebook.com Inc. cracks down on abusive applications
As the number of applications has over flown Facebook, its users have increased form 24 million in May 2007 to around 90 million today. This rapid growth has narrowed Myspace.com’s lead in the internet’s social network niche and helped privately held Facebook secure since a $240 million investment form Microsoft Corp.
Having so many outside applications on the side has caused some stress for Facebook, too. Some applications have included security holes that gave web surfers unauthorized peeks at the personal profiles of Facebook users. “Facebook has already removed about 1,000 abusive applications since it opened its Web site and plans to move even more aggressive as it establishes clearer ground rules for operating on its site” said Benjamin Ling, Facebook’s director of platform program management.

Fun at the Pump?!
Not only are the televisions relieving some stress, but they are bringing in some added revenue for gas station retailers, which have seen a shrink in retail due to an increase in fuel load costs and credit card fees.
It has been reported by Gas Station TV, which tracked its retailers’ sales, saying that stores with the TVs sell 75% more car washes and 69% more snacks if they are advertised. The companies that advertise on the televisions at each gas station, pay “rent” in exchange for placing the flat screens above the pump.
Once a customer starts the pump, the TV comes on. You can’t change the channel or volume, so the customer usually tunes in. It also appears that customers are more willing to buy the products that are advertised and also remember what was advertised. According to a Gas station TV and Nielson Media Research Study, 70% of the people who watched the ads remembered the product advertised, and 89% of customers were willing to buy the product after seeing the ad atop the gas pump.
“One of the pit falls for convenience store owners is that people pay at the pump,” says Richard Divine, head of the marketing department of Central Michigan University. “People don’t want to go inside anymore. But at the gas pump you have a captive audience.”
The main purpose of these TVs atop gas pumps doesn’t seem to be advertisements, but to distract the customer from the $4.22 per gallon of gasoline we are paying for.

Microsoft cuts price of 20GB Xbox 360 by $50 to make way for 60GB model
Although Microsoft adjusted its price of the 20GB 360, it did not change the price of the more basic Xbox 360: Arcade version (256MB, $280) or the Xbox 360 Elite ($450, 120GB). Microsoft released the Xbox 360 1 year ahead of competitors Nintendo corp. and Sony corp. As of the end of May 2008, Microsoft had sold 10.3 million Xboxs in the US. By comparison, Nintendo had sold 10.2 million Wii consoles, and Sony had only sold 4.5 million Playstation 3 machines. While Nintendo has consistently kept the price of the Wii at $250, Microsoft and Sony have been scrambling to cut their prices while still being able to obtain profit.
Cell phone trafficking causing increased loss of millions to cell phone companies
Cell phone companies have made it so easy for people to purchase cell phones that it only costs $15 to get one loaded with minutes. But a new problem has arisen for the cell phone companies, hackers and cell phone trafficking. In states like south Florida, New York, California, Georgia, Texas and elsewhere, traffickers have figured out that they can make huge profits by purchasing thousands of low cost “pay as you go” phones and hack into the software so that calls can be made on any cell phone network. After phones have been hacked into, they are sold all over the world and this costs the cell phone companies 10s of thousands of dollars. It is not illegal to unlock the software in your “personal” phone, but cell phone companies base their profits off of people buying their minutes. When numerous people hack into their phones for free minutes the phone companies lose even more money.
TracFone wireless is one of the leading producers of the cheap “pay as you go” phones. The company is suing traffickers across the nations and hoping to put a stop to this “siphoning of profits”. The unlocked phones are sold for between $40 and $60 above the TracFone discount price, and are frequently marketed in lots of 10,000 or more.
In recent months, TracFone has filled 39 lawsuits. Lawsuits similar to TracFone’s have been filled by AT&T, Nokia corp., Virgin Mobile USA Inc., and Motorola Inc.
TracFone and other companies have argued that, under federal law, the phones must be used with the minutes that were bought from the company that sold the phone. Companies like TracFone, lose profit when people buy minutes from other companies.Some cell phone companies disagree that cell phone hacking is wrong. A company called Incomtel, which is the self-proclaimed “Cellular supplier of the world” was among those companies that were recently sued by TracFone. In court, Incomtel lawyers argued, “that it is perfectly legal to buy phones from stored such as Wal-Mart, CVS and Target and modify them to work with any cell phone system.” Incomtel also said, “because the phones made by Motorola and Nokia are purchased on the open market and are repackaged for resale, Incomtel is under no obligation to incomtel.” So far, TracFone and similar companies have been winning more cases than losing

American King of Beers no longer
Going Completely Gas Free for $100,000
In the article, he discusses that although there aren't many being made currently (at just 1,800 a year) the trend seems to be following that by late 2010 there will be 20,000 cars on the market. As production continues to develop, Elon discusses, the price will continue to drop as well. Similarly as to our class lessons, he explains that "when you change the production quantity by a factor of 10, you can reduce the price by a factor of two." This follows the main idea of supply and demand.
Elon, goes on to further explain his products advantages which lead to consumers choosing his car over one that GM and Toyota may produce. The Telsa provides a completely gas free option for consumers. In the GM and Toyota cars, the gas is used complementary to the electricity. These cars do plug in, but unlike the Telsa, they use both forms of fuel. The idea that no gas is needed whatsoever is the most flattering advantage to Elon's product.
Deeper into the article, the idea of a carbon-cap or tax is discussed. Elon explains that he would rather see a tax due to the simplicity. Similar to our class lessons, this idea of a tax or cap provides a question. With the new electric cars-that do not burn fuel themselves, but use electric often produced by coal burning plants, and the development of hybrid's produced by GM and Toyota, there will be a rise in the production of carbon. Which idea is the best to limit this form of form of pollution?
New York Magazine Buys MenuPages Site
http://www.time.com/time/business/article/0,8599,1822290,00.html
Yahoo rejected Microsoft proposal. Economists who work in MenuPages and Yahoo have considered their profits.
Yahoo said it unsuccessfully reiterated its willingness to sell the entire company to Microsoft for $47.5 billion, or $33 per share — a bid that the software maker dangled in early May before withdrawing it in a pique over Yahoo Chief Executive Jerry Yang's demand for $37 per share.
The other side, New York Magazine buys Menupages site. Menupage's economist might think this way is much profitable than keep their company. Also, New York Magazine economist might think that this way is much profitable than they make their new own site.

Salvage yard haven for do-it-yourself customers
Today, if you recycle scraps you can receive up to $300/ton. Automotive Recyclers Association president, Sandy Blalock, said “At one time, a crushed car would go for $20 to $30 a ton. The market for scrap metal has skyrocketed so high that a family said they were able to put 3 kids through college by selling scrap metal on e-bay. Pull-A-Part, a self-service yard, only charges $1 for admission, $1 for wheelbarrows, also there is a flat fee price for each part. At times, customers are charged a $3 core deposit as an incentive to bring the old parts back so Part Galore can recycle it.
Wal-mart branches out to use locally grown produce
An obvious notice in the change in Wal-mart’s consumption of local produce is that it only used to buy a few peaches from a few producers, now Wal-mart buys 12 million peaches annually from 18 different producers. This move by Wal-mart could easily change the market for farmers. Restaurants have been willing to spend more money for fruits and vegetables they know have come from local farmers, something that Rich Priog says could change when Wal-mart moves into the territory and negotiates. Also, identifying locally grown food in stores aisles could relieve customer concerns, especially after recent salmonella outbreak linked to tomatoes that sickened at least 869 people across the country.

Blockbuster withdraws plan to acquire Circuit City
Blockbuster stocks have fallen since April, by 20%. The shareholders stocks have dropped below $3 from its peak near $31 in May 2006. Many investors are skeptical of the marriage between Blockbuster and Circuit City because both companies lost money last year. Circuit City reported that its loss tripled and same store sales plunged 11% in the quarter that ended May 31, 2008. Best Buys profit also declined by 7% last quarter ending May 31, 2008 (losing $85 million last year on revenue of $5.54 billion). After the announcement Circuit City’s shares dropped 34 cents, or 11.8% and Best Buy’s shares rose 27 cents, or 11.6%.

Rising Prices Due to Flooding in Midwest
Due to this natural disaster the price of corn and other crop food will rise and there might even be a shortage of supplies especially since we are now into the popular corn eating season. Most people think that the only economic problems occur to only the people that are located where the disaster took place but that is not the case. This disaster will cause problems all over the united states because the food will be more money and will be harder to find because of lack of supplies. What can the government do to help control this economic loss? Will setting a tax or a price ceiling/price floor? Where will the gain be, with the producers or consumers or neither? Do you think deadweight loss will be higher than normal?

TV's Shrink in the Big Economic Picture
What will be the result of this decrease in demand and an increase in inventories? The equilibrium quanitity and price will decrease. The prices on these luxury TV's will have to lower to clear the inventory, and many firms will have to cut back on production to adjust to the decreased demand. But industry analysts are hoping that the lower prices would stimulate more demand for these items, especially in the wake of increased travel costs. With gas at or exceeding $4.00 dollars a gallon in most places, maybe buying a cheaper big screen TV later this summer and staying home and watching a movie located at the beach will be just as nice as being at the beach.

Have gasoline prices really risen?
First of all, let's be sure that gasoline prices have really been rising--after all, lots of prices rise over time. What we're really interested in is the relative price of gasoline (that is, the price of gas relative to the overall price level). The chart below shows gasoline prices from 1976 to 2008. You'll see two lines in the chart: the blue line represents the "current" dollar price while the red line represents the "constant" (or inflation-adjusted) price of gasoline.

Notice that the constant dollar price of gasoline rose quite dramatically in the late 1970s and then steadily declined until the mid-1980s and was essentially flat until the late 1990s. Since then, the real (constant dollar) price of gas has again risen quite dramatically, reaching an all-time high just within the last month or so.
So, why is the price of gasoline rising? The simplistic answer is that it's all supply and demand. To explain a rising price it could be that the demand curve is shifting out to the right or that the supply curve is shifting to the left. What factors are most people pointing to as shifting these curves? How can we tell which factor is the dominant cause of the rising gasoline prices? (This question is analogous to Question 5 from Chapter 3's Problem Set II.)

Individual Choice and Advertisement
Advertisements always affect individual choice. The individual choice is the first
principle of economic, so it is very important for economy.
I think the most effective way to influence the individual choice is advertisement. Advertisement can let people the functions and features about a good. People must know everything about a good than they will consider buying it or not. So there is question that how people know about a good or product, a person does not know everything about the features of a good, we are not experts in every area. So what should we do when we want to buy or realize some commodities in our daily life? My answer is advertisement, advertisements exist everywhere in our life, when you walk in the street, open TV, and search the internet, you can see them every time in everywhere.
For instants, I want to buy a mobile phone, which phone should I choose become the first question, so most of people would to look for some advertisements about mobile phone, therefore people will open TV, search the internet, and buy a magazine to fine some advertisements about mobile phone, and compare the features and functions that are told by the advertisement, at the end they decide which phone they will buy. From the example, we know in the procedure advertisements play a very important role and have big influence on person’s decision.

Record Drug Bust in Afghanistan
Recently, officials have given warning of crack-down on the opium production to farmers and instead cannabis plants have been grown. In result, the country has a second drug problem to battle.
Drug dealers across the nation have been arrested and the police have taken account for a large portion of the opium production across the lands. However, if such business is being targeted and shut down, how will these farmers survive? Much of their crop is illegal, and police officials are being killed through the raids. Is crashing such a large market worth the risk of lives? These drugs are produced in other areas across the world and although Afghanistan is currently a top supplier, would it not be just as easy to move the locations of production? With this bust behind officials, what is the best route to continue to follow?

Food Is Gold, So Billions Invested in Farming
Wheat, corn and soybeans are important food in the world people. However, the supply of them is enough now. Therefore, the few investors are starting to investe to other metarials because wheat, corn and soybeans opportunity costs are not bigger than the others.Huge investment funds have already poured hundreds of billions of dollars into booming financial markets for commodities like wheat, corn and soybeans. But a few big private investors are starting to make bolder and longer-term bets that the world’s need for food will greatly increase — by buying farmland, fertilizer, grain elevators and shipping equipment.

Fuel Issues for Airlines
Airlines are stuggling to find ways to save money so they can buy fuel. These airline companies have been working overtime and extra hard to find a way to pay for these soaring ful prices. Southwest airlines have decided that power washing the jet engines to get ride of the dirt and grime, using less water in the bathroom facilities, and updating the passangers seats with lighter ones will all benefit their fuel comsumption. They believe that all of these things will save gas which will decrease the amount of spending in fuel.
Forty percent of the ticket price goes straight to fuel expenses, while a couple years ago only fifteen percent went to fuel. Do you think there is a possibility that airlines will reduce flights because they will not be able to afford the price of gas after a certain amount of time? Do you think this is the perfect time to update airplanes with these new "fuel-saving" ideas? Do you think these ideas will actually cut the costs of fuel? Do you think summer travelers will spend more money in plane tickets than spending more money in gas for their own care knowing they are paying for fuel in both circumstances?

Feeling the strain of increasing fuel prices
Continental could have created a model which showed that it would be cheaper to pay the 3,000 employees that are being laid off their remaining salary for the rest of the year then to have them up in the air working. Continental along with numerous other airlines have created models to show the overall expenses for each flight and the number of flights to determine how many flights they can have in the air before it becomes uneconomical or when the marginal cost becomes greater than the marginal benefit.

Is it rational to ignore some costs?
After reading Chapter 7 you will have been exposed to the basic paradigm in economics--namely, the rational man (homo economicus) model. The model posits that much of human behavior can be explained as if individuals made their day-to-day decisions by comparing the marginal benefits and marginal costs of various activities. For example, consider the decision facing a customer at Burger King. Let's imagine that our rational man has already consumed one Whopper. Should he buy (and eat) a second Whopper? Well, if the marginal benefit of another Whopper exceeds the marginal cost, then it is rational to gobble up another Whopper. What about a third Whopper? I suspect that at some point the marginal benefit of an additional Whopper will start to decrease (how much happiness can a third Whopper possibly give you?) such that it's not "worth it" to buy another one. Thus, the marginal benefit/marginal cost rule tells us "how much" to do of something. Namely, continue the activity up until the point where MB = MC.Marginal analysis, by its very nature, is forward-looking. A rational individual is always trying to compare the additional benefits versus the additional costs of her behavior. Not all costs, however, show up in the future. Some costs may have been incurred in the past and, consequently, are unavoidable. These are called sunk costs. According to homo economicus, sunk costs should be ignored.
Read the following episode from the life of Alex Tabbarok Do you think Alex made the right choice?
What are some other examples of sunk costs that people ought to ignore if they wish to emulate homo economicus? Can you point to anything from your own personal experiences?

Freeconomics?
Rarely do I come across a business press article that introduces (and applies) as many basic economic concepts as this one by Chris Anderson. Anderson makes the case that the internet (and the digital economy in general) has fundamentally changed the way businesses do business. In a digital economy, according to Anderson, competition necessarily drives prices to zero. Thus, the price of music, software, and movies, for example, will essentially be "free." The notion of a free good is alien to most introductory chapters in a typical economics text (such as your Krugman text). As Milton Friedman is famous for saying: TANSTAAFL! The basic argument against the concept of "free" is that we possess unlimited wants yet live in a world with scarce resources: to get more of one thing requires us to give up a little (or a lot) of something else.
Read Anderson's article and tell me if you agree or disagree with his main thesis. If you agree with his idea, can you come up with your own example of a product or service that will eventually be priced at zero? Explain why. If you disagree with his idea, can you explain what the "hidden price" is of the various examples he gives in the article?
