Cobb-Douglas Utility Function

Utility Function of Karim's Friend

Utility Function of Angela's Friend (u(t, c) = c + 75 ln(t))

An economist is modeling the preferences of two consumers, Priya and Quinn, for two goods: digital music tracks (m) and physical books (b). Priya's preferences are represented by the utility function U_P(m, b) = 2m + b. Quinn's preferences are represented by the utility function U_Q(m, b) = m * b. What fundamental difference in their consumption preferences do these two functions reveal?

Modeling Consumer Preferences for Complementary Goods

An economist is modeling a consumer's preferences for two goods: weekly hours of a video streaming service (s) and cups of gourmet coffee (c). The consumer's description of their preferences indicates that each additional cup of coffee provides a consistent, fixed amount of satisfaction. In contrast, the first few hours of streaming provide a great deal of enjoyment, but each subsequent hour provides progressively less additional satisfaction. Which of the following utility functions would be the most appropriate model for this consumer's preferences?
