Was the severe shortage for over two years an old marketing ploy called intentional scarcity, in which a company purposely keeps its hot product in short supply to build buzz. Or was it simply bad planning on Nintendo's part? What did this mean for households? What were the implications for Nintendo?

Furthermore, why did Nintendo drop the price of the Wii console in 2009? How would you expect this would affect company revenues?

As for the publicly funded roads - who might people consider to be free riders when it comes to the roads? Do you agree? What are some externalities, positive or negative, that public roads produce? Think of the case of new "luxury lanes" being made out of carpool lanes on the 110 and 10 freeways (which may extend to the 405 as well). Taxpayers paid for those lanes and pay to maintain them, but they are now only usable if you pay an extra fee. Is that fair?
