The country of Syldavia satisfies the assumptions of the basic Solow model. There is no population growth nor any technological progress. The production function is Y = AK^3 L^3. Using the notation from class, the parameters A, s, δ, and the labor force Lt = L have been constant for many years up to and including 2020. The economy is at the steady state. Suddenly, in 2020, a meteorite crashes on the country, and luckily does not destroy any installed capital nor does it kill anyone. What a piece of luck!
