Bad_(economics)

In economics, a bad is the opposite of a good. "Bads" can helpfully be thought of as any goods with a negative value to the consumer, or a negative price in the marketplace. Garbage is an example of a bad.

A bad is a physical object that lowers a consumer\'s level of happiness, or stated alternately, a bad is an object whose consumption or presence lowers the utility of the consumer.

With normal goods, a two-party transaction results in the exchange of money for some object, e.g. money is exchanged for a car. With a bad (such as garbage), however, both money and the object in question go the same direction, e.g. a household loses money and the garbage. The waste collector is being compensated to take the object from the consumer. In this way, garbage has a negative price; the waste collector is receiving both garbage and money, and thus is paying a negative amount for the garbage.

Goodness and badness are an inherently subjective declaration, however. As an example: two diners at a restaurant discover that the "secret ingredient" in the house specialty is peanuts. One of the diners is a peanut-lover, and the other is allergic to peanuts. In this case, peanuts are, in the same time and in the same place, both a good and a bad in economic terms.

Additionally, one and the same good consumed by the same individual can turn into a bad over time, and vice versa; cigarettes, when first consumed, may give a smoker a feeling of relieved anxiety and reduced stress. Continuing, long-term consumption, however, may have serious adverse effects on a smoker\'s health, thus turning the utility of cigarettes into the negative. On the other hand, some forms of medical treatment or side effects of medication may seem rather unpleasant to a patient at the time of treatment, but will greatly improve their health and well-being in the long run.
