3. Consider the model of team production in the slides (or text, if you have it). Let = 4, and the number of partners = 2. Each partner has 24 hours a day to divide between work and leisure. There are 24 hours available each day, and each partner has a utility function defined over leisure and income given by ui = [sqrt(24 - ei)] + yi. Leisure is total endowment of time minus the time worked, and income is denoted byy.

a) What type of utility function is this?

b) Why is this useful in this context?
