  • What about the linear case?

  • What about S-curves?

  • Think about the decision to buy or not to buy a certain product.

  • If the utility x obtained by buying a product is known, you don’t have to worry about it, but in reality, it is unknown.

  • Let’s express uncertainty and say N(x, e)

  • In this case, too, if the relationship between the amount of profit loss and utility is linear, then buying at x is correct.

  • But as prospect theory points out, there is a large coefficient on the loss side E(x) = x if x > 0 else k * x

  • In a situation where the price of the same product is decreasing or the utility x of the product is increasing with the same price, the larger the k, the more delayed the timing of the purchaseExperiment needed - innovator theory is reproduced.

  • ‘others are buying’ raises the estimate of x principle of social proof.

    • Is this a factor that causes bubbles to occurExperiment required
  • Utility of “buying what others have not yet bought

  • The negative utility of losing x amount of money depends on the amount of money you have.

    • I hesitated to buy a $3,000 technical book when I was in high school, but I am less hesitant now that I am working and have a comfortable income.
