  Market Madness? - Profit-making companies are invading areas once thought the exclusive preserve of government. (WSJ, 5/14/98).

  Roughly one in 20 federal inmates is now in a for-profit prison, and more than one in eight community-hospital beds is in an investor-owned hospital. Deregulation is shaking up once-drowsy industries like electric utilities, prompting a frantic scramble for dominance. Skilled people in endeavors from singing to software find that, like baseball's free agents, they can command once-unimaginable salaries if they exploit the market.

  Water, Water, Everywhere - America's New Drink? Water---Just Water (NYTimes, 1/20/98).

  This is water, just water---no sparkle, no fizz, no flavoring, and no guarantee that it's greatly different from what comes out of your tap.

  How much for that Beanie in the window? - More Proof That Grownups Are Nuttier Than Their Kids (WSJ, 12/27/96).

  When Smoke Gets in Your Eyes - FTC Sharply Criticizes Proposed Tobacco Deal--- Agency Says Profits Would Exceed Penalties Included in Settlement (WSJ, 9/23/97).

  A tobacco-industry spokesman, Scott Williams, rejected the FTC's report, saying it is "highly speculative and misses the point, which is that the price increases in the settlement are designed to maximize the reduction in underage tobacco use." He said the report "is based on assumptions that are at best inaccurate," such as the FTC's calculation that cigarette makers routinely pass on more than 100% of the cost of tax increases.

  Milk drinkers got some good news earlier this month, when a federal judge threw out one of the strangest federal regulations on the books.

• Experiment 6: Externalities

  Only in LA? - Actress Julie Newmar and Others Struggle With Noisy Leaf Blowers (Wall Street Journal, 12/3/97).

  Gas-powered blowers long ago replaced rakes and brooms in the well-groomed communities of Los Angeles. Over the past year, however, leaf blowers have become more than just instruments to tend lawns and tidy flower beds: They have become a call to arms, the latest symbol of the city's divisions.

  Don't Blow It - What's that quiet? L.A.'s leaf blowers fall suddenly silent (Seattle Times, 7/2/97).

  Permitting Pollution - Certificate Trading Program Reduces Acid Rain Emissions (WSJ, 10/3/97).

  Proposed by the Bush administration in 1990 as a novel, market-oriented solution to the problem of acid rain, the trading of what amounts to sulfur-dioxide-pollution permits has led to results that have exceeded expectations.

  Like a Rock - Deadly Crashes Increase Between Cars, Light Trucks (NY Times, 9/24/97).

  Peak Load Pricing to Alleviate Highway Congestion - Message in a bottleneck: It's time to start charging rush-hour commuters (US News and World Report, 12/30/96).

  [S]ince 1986, car travel has increased almost 40 percent, while highway capacity has barely grown. The author suggests that a possible remedy is "peak-period pricing," which means charging drivers for access to highways during peak times.

• Experiment 7: Monopolies and Cartels

  Enjoy the Discriminating Taste of Coke - Coke Tests Vending Unit That Can Hike Prices in Hot Weather (NYTimes, 28 October, 1999.

  While the concept might seem unfair to a thirsty person, it essentially extends to another industry what has become the practice for airlines and other companies that sell products and services to consumers. The falling price of computer chips and the increasing ease of connecting to the Internet has made it practical for companies to pair daily and hourly fluctuations in demand with fluctuations in price -- even if the product is a can of soda that sells for just 75 cents.

  Fortified Profits - U.S. Outlines How Makers of Vitamins Fixed Global Prices (NYTimes, 21 May, 1999.

  Packing the Planes - Airlines Rely on Technology To Manipulate Fare Structure (WSJ, 11/3/97.

  Playing Monopoly with Real Money - Toys 'R' Us Loses FTC Ruling With Marketing Implications (WSJ, 10/1/97.

• Experiment 8: Entry and Exit

  There's No Business Like Show Business - Why These 'Angels' Invest Thousands on Broadway (WSJ, 10/17/97).

  Two commandments of smart investing are to never let emotion interfere with your decisions, and never bet on a business you know nothing about. But if those rules were always followed, there would probably be no such thing as "angels," the old-fashioned slang term for well-heeled backers of New York musicals and plays.

  Amid Brewpub Binge, Sobering Tales - Eager entrepreneurs are pouring into the booming brewpub business--and some have wound up with hangovers (WSJ, 2/6/96 summary).

Driver's Mart plans to sell the reconditioned cars complete with warranties and 30-day return policies.

  Edmund's Selection of Used Vehicles - How much is that used car worth?

  Dive into some real world data and see if you can spot adverse selection in action. A prediction of the theory is that cars that are sold recently after being purchased have a higher chance of being lemons, and thus should command relatively lower prices. If you are interested in buying a used car, see the bargaining section below for some helpful links.

  For the past few weeks, the giants of the telecommunications industry have engaged in a high-stakes game of corporate musical beds that left some of the most eligible partners sleeping alone and created some awfully strange bedfellows.

• Experiment 13: Bargaining

  Escalation in a Legal Battle - How a $909 Dispute Generated $100,000 in Legal Fees (WSJ, 3/23/94 summary).

  You may have thought that the escalation auction in class, where your instructor auctioned a $1 bill to the highest bidder, but made the top two bidders pay for it was amusing, but contrived. Could anything like this ever happen in the real world? Listen up! (It's just this kind of incident where the actions of 95% of the lawyers give the other 5% such a bad reputation!)
