4 Use the data from Table 6.1 to calculate annual growth rates of GDP per capita for each country listed over the period 1950-2005. [Note: The annual growth rate z will satisfy the equation (1 + Z)55 � GDP200S /GDP,9 5 0' To solve this equation for z using a calculator, take logs of both sides of the equation.] You will find that Germany and Japan, two countries that suffered extensive damage in World War II, had the two highest growth rates after 1 950. Give a reason, based on the analysis of the Solow model, for these countries' particularly fast growth during this period.
