Alpha cares about his daily consumption c and leisure time t. His leisure time t = 24 − ℓ, where ℓ is the number of hours worked in a day. If he works ℓ hours in a day, he receives $wℓ income, which he consumes by the end of the day. Alpha’s daily utility function is u(c, t) = ct. 1. Write down Alpha’s budget equation which gives a relation between his daily consumption and leisure time. 2. Find the...
