Assume an economy consists of two agents, a and b. Individual a has available 1 unit of time which he divides between leisure ra​ and labor ℓa​ . Likewise, individual b has available 1 unit of time which he divides between leisure rb​ and labor ℓb​. Commodity x is produced by one competitive firm according to the production function: x=√L​ , where L denotes labor hired. The firm is fully owned by agent a. The utility function of the two individuals are: u(xa​,ra​)=xa​ra and u(xb​,rb​)=xb​rb​ . Taking the price of labor as the numéraire (i.e. w=1), find the competitive equilibrium for this economy.
