The law of motion

Starting from the law of motion for the aggregate capital stock set up the Solow model. In each step,

provide a brief description of the equation you generated. In your set up let n is the population growth

rate, d is the depreciation rate, s is the saving I I rate, z is the TFP. Use the following Cobb-Douglas

production function: Y = zK2N2. Write down the equation that describes the equilibrium output per person.

Using GDP (constant $US 2010), population growth rate, population, gross savings (% of GDP) data for

2018 (if that is not available use the most recent one) do the following calculations:
• The model generated output per person for Australia and Tunisia (Since the Solow model assumes z is

the same across countries, set z=1 for both countries. Also set d=0.1 for both countries).

Data generated output per person for Australia and Tunisia
Compare the model generated outcomes and the data generated outcomes and provide a critique for the

Solow model.
