Growth Rate of GDP = g_GDP = [changeY/Y] = [Y_Year2 - Y_Year1/Y_Year1] Using the data below calculate the growth rate for any four regions across with both sets of dates: period 1 from 1982 to 1950 and period 2 from 1950 to 2009 Also calculate the average growth rate of the period. Use the formula: g_Y = 1/T [ln(Y_r)-ln(Y_0)] Write the equation(s) for a price index. What is the consumer price index (CPI) and how is it constructed? Construct the CPI and provide the inflation rate for the example data
