ECO3152B: Macroeconomic Theory III PART B Instructions. Answer all questions in part B. 1. (20 points) Competitive Equilibrium and Pareto OptimalityConsider a one-period closed economy. The representative consumer has preferencesover consumptionand leisure. The utility function is( )=205+lnwhereis a positive constant. The consumer allocates theavailable units of timebetween leisure and work, so that+=represents the consumers time constraint.The consumer earns the wagefor every hour worked, receives dividendsandpays lump-sum taxes.In addition,the consumer pays aconsumption taxperevery unit of consumption good.The representativerm produces output with the Cobb-Douglas technology=¡¢1¡0  1The government takes the level of public good provisionas exogenous. The govern-mentnances its purchases by lump-sum taxes and consumption taxes. Assume thatthe government must run a balanced budget.(a)(10 points)Dene a competitive equilibrium for this economy.Be preciseabout the endogenous variables that characterize the equilibrium and about theexogenous variables of the model. State explicitly all conditions that dene thecompetitive equilibrium and provide their economic interpretation.(b)(10 points)Is the competitive equilibrium Pareto optimal? Explain your answer.2.(20 points) Consumption-saving problemConsider a consumption-saving problem of a consumer with the following preferences( 0)=ln+ln00 ·1whereis the consumption in the current period, and0is the consumption in thefuture period. The consumer receives exogenous endowmentsand0The consumercan borrow and lend freely at the rate¸0There are no taxes.(a)(10 points)
