Brazil has the following per-worker production function:

y=4k^0.05

Population growth rate is 0.04, depreciation rate is 0.03. S= national saving and Y is national output where S=0.4Y.

1. what are the steady state value of output per worker, capital-labour ratio and consumption per worker?
2. If national saving increases to 0.5,what are the values of output per worker, capital-labour ratio and consumption per worker?
3. If the depreciation rate increases to 0.04,what are the values of output per worker, capital-labour ratio and consumption per worker?
