By manipulating the equations of the Solow model mathematically, it is possible to make more precise quantitative statements about the behavior of growth rates over time. For example, one way of qualifying the principle of transition dynamics is with the following equation.
g = 3 X (ln y* - ln y0) + 2
where g denotes the growth rate of a country over the next 10 years (in percentage points), 1n denotes the natural logarithm, y0 is the per capita GDP of a country in a steady-state (relative to the United States).
Of course, we don't usually know a country's steady-state position vis-Ã -vis of the United States. However, we do observe its growth rate. This question asks you to consider the facts from recent growth experiences in the table below.
Country | Current rate | Steady-state | g |
United States | 100 | 2 | |
Ireland | 86 | 4 | |
Russia | 21 | 5 | |
Brazil | 17 | 2 | |
China | 7 | 9 | |
India | 5 | 6 | |
Ethiopia | 1 | 5 |

(a) Using those facts and the equation above, fill in the last column of the table. That is, offer a projection of where countries are headed in the long run.
(b) Provide a one-paragraph discussion of your results.
