Yeah, I know what externalities are, but I was assuming that positive ones and negative ones cancel out (I’m not sure how this plays out in real life and I’m sure they don’t cancel out, but there are positive externalities in a freely competitive market). In a two agent transaction, a third party, or society overall may be made worse off, with the two agents paying no cost of the externality. For example, Google makes a search engine and enters into contracts with businesses that wish to advertise through Google. This transaction that benefits Google and its employees and shareholders, as well as businesses that wish to advertise, also has a benefit in that it makes the world’s information more easily accessible, and hence saves time and resources for people who would otherwise either spend more time searching for information or not know about things that they do because of things they found on the Internet that they otherwise wouldn’t know about. (Since we don’t pay the full cost of the accessibility of information on the Internet, it’s a positive externality of the transaction between Google and the advertisers…assuming that I’m not in error in stating that this is indeed positive, and not negative).
The definition of an externality is:
(Wikipedia: Externality)
I believe that these positive externalities are nothing other than the “invisible hand” that Adam Smith spoke of, and that beyond a certain threshold of regulation in any given industry or sector of the economy, you lose these positive externalities…but that’s just a speculative opinion.
In the real world, I strongly support regulations that eliminate negative externalities, such as the ones you mentioned. But I think that there needs to be a systematic process by which unnecessary regulations can be revised, set to expire, or devolved to the state level, where the effect of the regulation’s nonexistence or variants of it will manifest their effectiveness and propriety in competition with each other.
Darwin said that natural selection was the driving force of evolutionary change of life forms. For our government’s effectiveness to progress, that is adapt to new economic and productive realities, federalism and states’ rights isn’t enough. These states need to have different methods, regulations, and approaches so that the variation that is needed for the natural selection to act on can exist.
Sorry, I veered off topic.
P.S. How can you calculate what the average person, smokers and nonsmokers alike, value nonsmoking vs. smoking? Would you be willing to allow smokers in the workplace and have the nonsmoking laws repealed if it could be found that the law actually decreased overall utility, even though it diminished yours (assuming you’re a nonsmoker). If utility cannot be accurately measured, will there ever be a way to objectively settle whether this regulation, for instance, is justified on a utilitarian basis? In a situation where you don’t know whether the average utility falls on the side in favor or on the other hand opposed to a regulation, do you think it’s better to err on the side of caution (keeping/adding the regulation), or on the side of “letting the market work?”
