*** the shopkeeper suffers the "unseen" costs of not being to do something else with that money | |||
*** additionally, the opporutnities to fix broken windows may create an "unintended consequence" of a "perverse incentive" for glaziers to go about breaking windows in order to make money fixing them | |||

* ''Parable of the broken window'': | |||
** a shopkeeper has a careless son breaks a window | |||
*** his neighbors argue that broken windows keep "glaziers" (window-makers) in business | |||
**** if it costs 6 francs to fix, they argue, the money spent on the window is productive, as it goes to the glaziers | |||
*** Bastiat replies that, yes, money has thus circulated, but "it takes no account of what is not seen" (''ce qu'on ne voit pas)'' | |||
**** the shopkeeper can't spend those 6 francs on something else of his choosing | |||
**** or, perhaps, he has another need for 6 francs that he can not now fix | |||
**** therefore the accident of the broken window prevents the shopkeeper from using his money more efficiently | |||
*** Bastiat writes, "Society loses the value of things which are uselessly destroyed" | |||
*** the parable also develops "the law of unintended consequences" | |||
**** ex.: if the glaziers figure out they can pay a boy 1 franc to break windows, and they can still make a profit at 5 francs per window, | |||
***** there will thereby exist a "perverse" incentive to break windows | |||
****** "perverse incentive" = an incentive that produces a negative outcome | |||
** economists have argued over the "opportunity costs" of | |||
*** disasters (hurricanes, earthquakes which require repair and thus create jobs & economic activity) | |||
*** wars (spur economic activity and mobilization) | |||
** however, whatever the benefit it does not account for Bastiat's "unseen" costs and cannot in any way outweigh the suffering, death and loss of choice created by the disaster or war | |||

* Examples: | |||
** If you own land on an urban road, and you decide to build condos on it, what else might you have done, and what would that have cost -- or earned -- for you? | |||
* Questions: | |||
** If the U.S. imports oil from Saudi Arabia, is the U.S. giving up the potential of its own oil industry? | |||
** If Saudi Arabia relies on oil, what is the cost of that reliance? | |||
