Recently I began thinking about why the use of tokens for money is so popular. In casinos, I think that it is well justified, but there are some cases when those arguments are not useful. For example, why would an amusement park make you buy tickets that say exactly how much is it worth (for example, buying a ticket for 5 dollars at the cost of....5 dollars). You know how much money you are spending, so the link between value and tokens is not broken. What positive effects does that measure have in the amusement park economy? Why?

  1. Disneyland takes in about \$8 billion a year --- not all of it through tokens, but let's say they sell, oh, \$4 billion a year worth of tokens. People often buy tokens several hours before they use them, so Disneyland gets to hold \$4 billion a year for, oh, say, four hours longer than they would without tokens. At 6\% annual interest, that's worth about \$100,000 a day to them.

  2. Some people don't use all their tokens and don't bother to cash them in, which means you're effectively charging those people more than others. So tokens can be an effective way to price discriminate. To make sense of this, you'd have to explain why the people who don't cash in the tokens are (on average) the people you want to discriminate against, but I don't think it would be hard to come up with a plausible story along these lines.

    I am a bit skeptical about your first point. I can't imagine Disneyland is accruing interest on these deposits. Much will be held in cash, which yields no return and I doubt the rest is being invested or deposited considering the need to be very liquid in this arrangement.

    I think your second point valid.

    In addition, I think the ability to control the market is useful.

  • could be expanded by challenging the author's assumption of universal 1:1 exchange rate. If the park has market power, then it likely wants to price discriminate (via targeted coupons, say). Some people get a 1:1 exchange rate, and some people get a 1.1:1 exchange rate. Etc.

  • Do amusement parks do the ticket thing any more? I thought that went out during the 1980s. Disney World is "ride all day." Other amusement parks I know of are also "ride all day." – Bill Jan 02 '17 at 18:53
