This figure is a scatterplot of the change in the unemployment rate on the horizontal axis and the percentage change in real GDP on the vertical axis. Each point present one year. The figure shows the increase in unemployment trend to assoiated with lower-than-normal growth in real GDP. The correlation between these two variable is -0.085. I also found that when unemployment increases, real GDP decreases. This obeys Okun’s law. Comepare 1970-2013 period to 1949-2013, 1970-2013 has greater R^2 and the reason is in the short, unemployment has greater impact on RGDP. I found that when unemployment increase, real GDP decreases. This obeys Okun’s law.
