Tutorial on Economic Growth 1 Nicola Viegi 1 True - False - Uncertain Justify your answer with a short argument. 1. A higher saving rate alone can sustain higher growth of output forever. 2. The golden-rule level of capital tells us that the highest level of consumption in steady-state is achieved when the saving rate is equal to 0. 2 Solow Model of Growth Suppose that the production function is given by Y = 0 : 5 p K p N . As- sume that the size of the population, the participation rate, and the unemployment rate are all constant. 1. Is this production function characterized by constant returns to scale? Explain. 2. Transform the production function into a relationship between out- put per worker and capital per worker. 3. Derive the steady state level of capital per worker in terms of the

Derive the equations for steady-state output per worker and steady-state consumption per worker in terms of s and & . 5. Let & = 08 and s = 0 : 16 . Calculate the steady-state output per worker, capital per worker, and consumption per worker. 1 6. Let & = 08 and s = 0 : 32 . Calculate the steady-state output per worker, capital per worker, and consumption per worker. 7. What is the e/ect of an increase in the saving rate on output per worker over time? Show the transition from s to s 1 graphically. 8. Explain what happens to the level of output per worker and the growth of output per worker when the saving rate increases from s to s 1 . 2...

### 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.
