Hi all, currently, I have two data of y for each country - y in 1988 and y in 2014. My goal is to calculate the ratio of y2014 to y1988 for each country. So I've separated the y values into y1988 and y2014. However, I'm not sure how to shift y2014 up a column so that i can delete the repeated country in order to calculate the ratio for each country.

Can someone please help me with this? Thanks in advance!
