Empirical Analysis on determinants of unemployment QUESTION

[econstudent1]

Hi Everyone,

I am writing a paper for my college econometrics course on the determinants of unemployment in Germany and Italy from the time period 2000-2013. So for the majority of my variables I have quarterly data (wage rate, unemployment rate, interest rate, exchange rate...etc..) but a few variables (inflation, education level, youth population in population) do not have quarterly data! Is there anyone I can use annual data with my quarterly data in the regression process (using stata btw).

Thanks for the help.
