Dear Statlisters,

I am currently writing my thesis and doing research on the effect of changes in the marginal tax rate on the growth of GDP. I am using panel data and have observations for 161 countries over a time span of 1990 untill 2017. One of my dependent variables should be the growth rate of the GDP for the time period 1990-2000 to control for certain institutional and cultural factors that influence cross-country differences in long-term growth. How do I code this in Stata?

Thanks in advance.

Best regards,
Jarne Beneens
