Suppose we have a data set covering 70 countries that includes data from 1980 and 1990 on gross domestic product (GDP) per capita and average years of education of the population. We estimate the following regression: 9080iiiysaße?=++ Where 90iy? is the percent change in GDP per capita from 1980 to 1990 and 80is is the average years of education in each country in 1980. a) What is the interpretation of ß ?
