Question
Consider the Robinson Crusoe economy, where there is only one
good in the economy that is produced by one firm, which is owned by Robinson
Crusoe. Robinson Crusoe's utility function is given by u(x, y) = x¹/³y²/³ where x
denotes the amount of consumption of the good and y denotes the amount of leisure.
Suppose that there are 24 hours of time that Cruose can allocate between leisure
and work. For the firm side, suppose that the production function is f(1) = √l,
where I denotes the amount of labor. Let p be the price of the good, and w be the
wage rate.
(a) Let II be the profit of the firm. Using II, along with the notation above, write
down the budget constraint of Robinson Crusoe as a consumer.
(b) Solve the consumer problem and find the demand of the good and leisure.
(c) Solve the firm's profit maximization problem.
(d) Let w 1. Find the equilibrium price of the good, the demand (and supply)
of the good, and the amount of labor.
