More seriously, many of our important decisions involve balancing the value of consumption now “Introduction: The Plight of the Economist” pg. 1 against consumption in the future.

Life is about trade-offs, and so is economics. In short, getting out of bed in the morning “The Power of Markets” Pgs and making breakfast involves more complex 8-11 decisions than the average game of chess.

The real cost of at making basic consumer goods like food and something is what you must give up in order to get it, clothing. Rather, the primary cost of raising a child which is almost always more than just cash.

The point is that it is it becomes more attractive to us. You can learn that now more expensive to have eleven of them than it by deriving a demand curve, or you can learn it by used to be. The data speak to the point: The shopping the day after Christmas, when people snap average American women had 3.77 children in 1905; up things that they weren’t wiling to buy at full price she now has 2.07—a 45 percent drop. several days earlier. Conversely, when the cost of something goes up, we use less of it. This is true of Economics—by Example everything in life, even cigarettes and crack cocaine. Economists have calculated that a 10 percent By David A. Anderson decrease in the street price of cocaine eventually causes the number of adult cocaine users to grown “What’s to Love about by about 10 percent. Similarly, researchers Economics?—Virtues of the estimated that the first proposed settlement Economic Way of Thinking” between the tobacco industry and the states (rejected by the US Senate in 1998) would have Page 2 raised the price of a pack of cigarettes by 34 percent.

Of course, society has already raised the class allows you to launch a new career, like Adair, or cost of smoking in ways that have nothing to do with to get treatment for a deadly illness, the substantial the price of a pack of cigarettes. Standing outside an benefit exceeds the limited cost of the first class Economics—Chapter 1 Readings missed, which might be a few hours of extra reading and not taking and note copying. The second most important reason to skip class might be that your sports team has a competition. The third best reason might be that you’re simply not in the mood. As the reasons to skip become more trivial, the costs of additional misses mount. In running, they say that if you miss 1 day of training, only you know it; if you miss 2 days, the competition knows it; and if you miss 3 days, the crowd knows it. In education, an analogous story might be that missing 1 day of class affects your conscience; missing 2 days affects your grade; and missing many days affects your future. In order to determine the number of skips that will make you as well off as possible, you should skip until the additional benefit no longer exceeds the additional cost. (Don’t get the wrong impression; if you’re not interviewing, ill, or bereaved, the optimal number of skips may well be 0.) With the additional benefit falling and the additional cost rising, any subsequent skips do more harm than good. Economists call the additional benefit from 1 more of something the marginal benefit and the additional cost of 1 more of something the marginal cost. Thus, you should skip until the marginal cost equals the marginal benefit. You weigh marginal costs against marginal benefits every day. You know that eating too much pie can make you gain weight, but the first few bites create a lot of pleasure and not a lot of weight. As your hunger is satisfied, the benefit of each additional bite decreases and its cost (in terms of excessive caloric intake) increases. Eventually, the marginal cost of another bite of pie will exceed its marginal benefit, and it’s time to stop eating. If it’s the best pie you’ve ever tasted, the marginal benefit is higher, and you’ll eat more of it. Sometimes even indigestion is well justified. In 2005, high marginal benefits led Ted Janus to eat 6 pounds of shoofly pie in one sitting—he won $2000 and fame at the Alka- Seltzer U.S. Open of Competitive Eating. The study of where marginal benefit meets marginal cost leads to the efficient outcomes that economists cherish. How many hours should you spend in the library? How many laps should you swim in the pool? How much time should you spend in the shower? The answer is always the same: Just do it until the marginal benefit equals the marginal cost and you couldn’t do any better.
