Based on article "Technology and economic growth: From Robert Solow to Paul Romer" by Rui Zhao, Solow mentioned, technology (At) and capital per unit of effective labor (Kt) have a significant influence on a country's ability to “catch-up” or “converge” to a steady-state level (K*). In brief define what it means by a steady-state level.
Based on article "Technology and economic growth: From Robert Solow to Paul Romer" by Rui Zhao, Solow mentioned technology (At) and capital per unit of effective labor (Kt) have a significant influence on a country's ability to “catch-up” or “converge” to a steady-state level (K*). Using the central equation of the Solow model, discuss the influence of At and Kt on country's ability to grow and move to a steady-state level (K*).

- Production function is given by Y = 3K"(AN)!-a, where a=2/3. The rate of depreciation of capital is equal to 12 percent, the rate of technological progress is equal to 5 percent, and the rate of population growth is equal to 3 percent. The economy was in the steady state at time t and the level of technology was equal to A:=30. Use the Solow growth model to answer the following questions. (Please fill in numbers; use a comma as a decimal separator: 10,5) 1. If the saving rate s=40 percent, the steady state level of output per unit of effective labor at time t is equal to 2. If the saving rate s=40 percent, the steady state level of consumption per unit of effective labor at time t is equal to 3.

Consider two countries: Fritolaysia and Khandibar. Currently, real GDP per person (average income) is $60,000 in Fritolaysia and $20,000 in Khandibar. Suppose you want to project what the real GDP per person will be in each country 100 years from now. The following formula shows how to compute the average income in n years, where g represents the growth rate of real GDP per person (in decimal form-that is, 1.5% is entered as 0.015): Average Income in n Years Current Average Income x (1 + g)" Use the growth formula to find the correct amounts to select to fill in the following table.
