Hello everybody,

I'm quite new to Stata and I would like to generate first differences of all my variables, i.e. x(i,t)-x(i,t-1). Additionally, I would like to lag my variables by one period, i.e. x(i,2010) should then be x(i,2011). I hope that makes sense.
Could someone help me out here please?

Thanks a lot !

Have a nice day,

George
