TA section 05 February 27, 2009 Imagine an economy where the representative agent preferences are log c 1 + ° log (1 ° l 1 ) + ± [log c 2 + ° log (1 ° l 2 )] and he or she chooses to decide how much to consume and work in period 1 and 2. The representative agent has a source of income by supplying labor with w 1 and w 2 for period 1 and 2 respectively. In addition, the representative agent chooses to save, a 2 , which has net return of r . Assume there is no initial asset, i.e. a 1 = 0 , and labor supply is normalized so that it cannot exceed 1 .The °rm produces a °nal good that uses labor and capital as input. Labor demand by the °rm is met by labor supply of representative agents and capital demand is also met by saving decision of representative agents, that is l d

Unformatted text preview: d t = l s t for t = 1 ; 2 and k 2 = a 2 ( we assume k 1 = 0) . The &rm pays rental rate, r , for capital that is &nanced by representative saving asset in period 2 and also w 1 and w 2 for labor wage. The production function of the representative &rm is y = l 1 for period 1 and y 2 = k & 2 l 1 & & 2 with ² < 1 . Problem 1 Formulate the problem of the household. Problem 2 Solve the problem of the household. Problem 3 Formulate and solve the problem of the &rm. Problem 4 Does the &rm have pro&ts in both periods? Proof and explain. Problem 5 Find an equilibrium for this economy: Problem 6 Formulate the social planners problem: Problem 7 Solve the social planners problem: 1...

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
