In the Solow model, faster productivity growth (e.g., higher z) tends to raise the steady-state rental rate of capital. 

Nation W has the same steady-state capital-output ratio as the modern United States. In Nation W, the savings rate is 15%, the annual depreciation rate is 1%, and productivity never grows (z=0%). What ‘s the annual population growth rate in Nation W?

In a Solow model with competitive markets, what is alpha (α)?

If capital can move easily across countries in search of the highest rate of return, then a higher tax rate on capital tends to reduce equilibrium worker wages. 

Consider a Baby Solow economy where TFP = 1, capital starts off at K0=1, the savings rate is 50%, and the annual depreciation rate of capital is 10%. What is the steady-state capital stock? 

Dietz reports in Fully Grown that corporations appear to move their innovative activity from state to state partly in response to tax rates.

In an economy with a simple Cobb-Douglas production function and competitive markets, the worker’s equilibrium share of output is (1-s), 1 minus the nation’s savings rate. 

Across countries today, nations with higher population tend to have higher levels of GDP per person. 

Rates of firm entry and firm exit have increased over the last few decades.
