Contact rate for word of mouth

Jean-Jacques Laublé makes a good point about the traditional word-of-mouth product diffusion model not working in quite the same way for services such as telephone service contracts, internet service subscriptions, or rental cars. There are (at least) two reasons why the *service* word-of-mouth mode...

Contact rate for word of mouth

Hello Vittorio, To calibrate a word-of-mouth model, I typically break the word-of-mouth sales into real world pieces and then calibrate the pieces. In word of mouth models Ive built, Ive separated sales into two categories: word-of-mouth sales, and repurchases (by customers who are in the installed ...

Production and Sales Quotas

Today I read an article about Toyota surpassing Ford in vehicle sales to become the number two in total annual sales, behind GM. (However, Ford still leads Toyota in car sales, if Toyotas heavy truck division is excluded from the numbers.) Fujio Cho, president of Toyota, is generally considered to b...

Niall, Usually, I believe that its a bad idea to run the beer game as a computer simulation. There have been dozens of attempts at converting the beer game into a computer simulation. In fact, Ive tried this a couple times myself. Few of these computer versions are very much fun. Thats because the b...

One nice feature of the multiplicative attractiveness function is that if any attribute goes to zero, the whole function returns a zero. So, if you are selling a product a product, the attractiveness of the product could be: Product Attractiveness = Availability Effect x Wait Time Effect x Price Eff...
