Pricing Models

This is an interesting article about variations on the pay-what-you-wish pricing model that has gained some attention in the last few years.

The band Radiohead famously offered their album “In Rainbows” on their website and asked fans to pay whatever they wanted for the download.  The actual sales numbers are well-guarded, but  it appears to have been a success.

The above article details how an amusement park merged the pay-what-you-want approach with a half-goes-to-charity approach (telling the customer that half of the purchase price is donated to charity).  The product in question was a picture of the customer riding a roller coaster.  Let’s abbreviate with PWYW (Pay What You Wish), HGTC (Half Goes to Charity), and PWWTY (pay-what-we-tell-you):

Percent Sales Average Sale Price
PWWTY .5% $12.95
PWWTY & HGTC .57% $12.95
PWYW 8.4% $0.92
PWYW & HGTC 4.5% $5.33

When given the opportunity to pay whatever they wanted, participation increased dramatically, but revenue was still low–only 92 cents per person.  But when combined with the half-goes-to-charity approach, participation was much higher and the price paid was significantly higher.  Even after taking out the half for charity, revenue was still up by a factor of three!

This is a very interesting approach to pricing, and there are some cool psychological and sociological principles at work here.  And it’s another set of factors to consider when that salesperson is working on you.

02/12/2012 — Another Permutation Day!

Today we celebrate our second Permutation Day of the year!  I call days like today permutation days because the digits of the day and month can be rearranged to form the year.

We enjoyed our first permutation day of 2012 just 21 days ago.  Exactly three weeks apart!  That seems unusual.  I also wonder “How close could two permutation days be?”

Celebrate Permutation Day by mixing things up!  Try doing things in a different order today.  Just remember, for some operations, order definitely matters!

GIF Animations of Simple Machines

World of Technology has several great GIF animations demonstrating some fundamental mechanics:

Seen at right is the radial engine.  The constant velocity joint is my favorite, but it’s also great to learn how a sewing machine really works!

Some great visualizations of interesting and intricate 3D geometry and engineering.
