Hello all,

I want to create a dummy variable that removes the effects of the financial crisis. I have a panel data set with 29 countries and 11 years from 2006-2017. The independent variables that I have are: Immigration, Emigration, Human Capital and Labour Productivity. My dependent variable is GDP.

I wish to create a dummy variable that will omit the data collected for 2009. The reason I want to create a dummy variable is because I do not want to drop the data. I want to see the effects that my independent variables have on GDP when 2009 is omitted as the coefficients for my variables might change when I run my regression and by running a regression that somehow does not include 2009's data points I can capture that change. Can someone please advise me on the coding to use to create such a dummy?

Thank you in advance,
Mikesh Lukka
