MARGINAL ANALYSIS The owner of a small pizzeria is deciding whether to increase the radius of delivery area by one mile. What considerations must be taken into account if such a decision is to increase profitability?

TIME AND INFORMATION It is often costly to obtain the information necessary to make good decisions. Yet your own interests can be best served by rationally weighing all options available to you. This requires informed decision making. Does this mean that making uninformed decisions is irrational? How do you determine how much information is the right amount?

Case Study: A Yen for Vending Machines ? Do vending machines conserve on any resources other than labor? Does your answer offer any additional insight into the widespread use of vending machines in Japan? Reference Case Study: A Yen for Vending Machines ? Japan faces a steady drop in the number of working age people. Here are three reasons why: (1) Japan's birthrate has dropped to a record low, (2) Japan allows little immigration, and (3) Japan's population is aging. As a result, unemployment has usually been lower in Japan than in other countries. For example, Japan's unemployment rate in 2010 was only about half that of the United States and Europe. Because labor is relatively scarce in Japan, it is relatively costly. To sell products, Japanese retailers rely more on physical capital, particularly vending machines, which obviously eliminate the need for sales clerks. Japan has more vending machines per capita than any other country on the planet-twice as many as the United States and nearly 10 times as many as Europe. And vending machines in Japan sell a wider range of products than elsewhere, including beer, sake, whiskey, rice, fresh eggs, beef, vegetables, pizza, entire meals, fried foods, fresh flowers, clothes, toilet paper, fishing supplies including bait, video games, software, ebooks, toys, DVDs, mobile phone recharging, and even X-rated comic books. Japan's vending machines are also more sophisticated. Newer models come with video monitors and touch-pad screens. Wireless chips alert vendors when supplies run low. Some cigarette and liquor machines have artificial vision that reportedly are better at estimating age than are nightclub bouncers. Sanyo makes a giant machine that sells up to 200 different items at three different temperatures. Some cold-drink dispensers automatically raise prices in hot weather. Thousands of machines allow cell phone users to pay by pressing a few buttons on their phones. As noted earlier, it is common practice in the United States to shake down vending machines that malfunction. Such abuse increases the probability the machines will fail again, leading to a cycle of abuse. Vending machines in Japan are less abused, in part because they are more sophisticated and more reliable and in part because the Japanese generally have greater respect for private property and, consequently, a lower crime rate (e.g., Japan's theft rate is about half the U.S. rate). Forty percent of all soft-drink sales in Japan are through vending machines, compared to only 12 percent of U.S. sales. Japanese sales per machine are double the U.S. rate. Research shows that most Japanese consumers prefer an anonymous machine to a salesperson. Despite the abundance of vending machines in Japan, more growth is forecast, spurred on by a shrinking labor pool, technological innovations, and wide acceptance of machines there.

Pitfalls of Economic Analysis Review the discussion of pitfalls in economic thinking in this chapter. Then identify the fallacy, or mistake in thinking, in each of the following statements: a. Raising taxes always increases government revenues. b. Whenever there is a recession, imports decrease. Therefore, to stop a recession, we should increase imports. c. Raising the tariff on imported steel helps the U.S. steel industry. Therefore, the entire economy is helped. d. Gold sells for about $1,000 per ounce. Therefore, the U.S. government could sell all the gold in Fort Knox at $1,000 per ounce and reduce the national debt.

ASSOCIATION VERSUS CAUSATION Suppose I observe that communities with lots of doctors tend to have relatively high rates of illness. I conclude that doctors cause illness. What's wrong with this reasoning?

Case Study: College Major and Career Earnings Because some college majors pay nearly twice as much as others, why would students pursuing their rational self-interest choose a lower paying major?
